    <p>It was shown that the color of materials in a closed space can be measured from the outside of space under diffuse illuminations by using a concave glass as a partition. The measurement accuracy is <i>ΔE*<sub>ab</sub></i> = 0.9 in average for 24 colors of the standard color chart, where <i>ΔE*<sub>ab</sub></i> is the color difference in <i>L*a*b*</i> (D65/ 2-deg.) color space of JIS Z8781-4. It is lower than that of the conventional colorimetry without a glass partition, in which the measurement accuracy is <i>ΔE*<sub>ab</sub></i> = 0.7 in average; it is, however, high enough compared to that of visual colorimetry.</p>

    In the process of heat-treating of materials during food processing by employing hot air or high temperature steam, the gas flow temperature, humidity, and pressure significantly affect the processed materials. In this study, we developed a humidity-measuring device that can continuously measure hot air flow above the boiling point. The measuring method is based on the principle of the psychrometer. Porous ceramics processed by injection molding are used as the wetted material for a wet-bulb thermometer. Accuracy is evaluated by using a humidity generator that can generate arbitrary humidity over 100°C of humid air to superheated steam. The measurements were conducted under gas flow temperatures ranging from 160°C to 300°C, and at a gas flow velocity of 3 m/s.

    This study investigated the effects of cooking and placement conditions, heat capacity of an oven plate, and thickness of meat samples upon change in their internal temperatures after oven cooking.In the condition wherein the oven plate was covered after oven cooking, the internal temperature of the samples was maintained at over 75°C. This temperature was maintained for a longer duration than that for the condition wherein the samples were not covered. The heat capacity of the oven plate (weight-to-area ratio) affected the retention time of the central temperature (over 75°C) of the samples. The thickness of the samples had negligible effect on the retention time. The retention time of the central temperature (over 75°C) of the samples was predicted using the improved calculation model. The values of the calculated time were similar to those obtained through actual measurement, which confirmed the validity of the heat transfer model.

    This study analysed the effects of the heating capacity of oven plates and the heating ability of ovens on the internal temperature of meat after oven cooking at 230°C. The temperature of the samples increased with the increase in the heating ability of ovens. Further, the overall temperature after cooking increased with the increase in the heating capacity of the oven plates, and the time required to attain an internal temperature exceeding 75°C also increased.As the duration of covering the samples after heating was reduced, the percentage of weight reduction decreased, and the samples became softer. These findings revealed that covering the cooked meat until a maximum internal temperature was attained kept it hygienic and enhanced its taste.

    <p>In a previous paper, we reported on the performance of a device developed for rice seed disinfection. To treat the rice seed such that its temperature after heating (<i>T<sub>fin</sub></i>) is 75±1°C,the device elicits a control effect equivalent to or more effective than the conventional hot water treatment against rice seed-borne diseases, and without the negative effect of excess heat on seed germination. In this study, we aimed to develop a process control method for <i>T<sub>fin</sub></i> using Predictive Functional Control. In particular, we aimed to calibrate and validate a prediction model for <i>T<sub>fin</sub></i> using the process conditions of the device. We created a multiple linear regression model to predict <i>T<sub>fin</sub></i>, which uses gas humidity, heating time, and other process conditions as predictor variables. The model can predict <i>T<sub>fin</sub></i> within the standard error of 0.5°C in the range of 66.0 to 82.7°C. This result indicates that it is possible to apply the model for device operation and control.</p>

    The objective of this study was to use a quasi-experimental design with a control group to verify the effectiveness of an education program, and to investigate the effects of improved energy-conservation awareness on students' behavioral intention using the visualization method. The education group improved for all factors following the program, and a significant difference was observed in their "motivation to learn about energy" after the program compared to before (p<0.05). Further, their "usefulness of visualization" improved significantly compared to the control group (p<0.05). In addition, excellent goodness of fit was obtained for the model of the improvement of behavioral intention. Based on these results, it was determined that the implementation of this energy-conservation education program using the "visualization method" was effective, with the results suggesting that this method, along with the increased awareness through visual experience, can contribute to the formation of attitudes and increase behavioral intention. This educational system in an energy-conservation program using the visualization method was effective. Moreover, a model of the mechanism for the improvement of behavioral intention for energy conservation was presented.

    Hot air, both dry and moist, has been widely used for heating and/or a reaction atmosphere in a broad range of industrial fields including food processing, material drying, and other heat treatments. In a process that uses hot air and superheated steam, the gas flow temperature, pressure, and humidity inside the treatment chamber have a major impact on the quality of the finished product. However, there is no simple method of measuring humidity that can be used over an extended duration in applications that use superheated steam at temperatures above 100°C. In this paper, we introduce a device developed for measuring humidity, which consists of a wetted porous ceramic probe with thermocouples, a water retention control system, and computing devices. The measured humidity (steam mole fraction) is calculated from the measured wet- and dry-bulb temperatures using the adiabatic saturation line equation on which we previously reported. The equation was extended to enable its application to temperatures of up to 350°C and a humidity up to that of superheated steam. Accuracy measurements were conducted with a humidity generator and a gas flow temperature of 200°C, a gas flow velocity of 3 m/s, and steam mole fraction ranging from that of hot air to that of superheated steam. The cause of any errors was investigated.

    In order to raise efficiency and to reduce the costs associated with chemical-free, environment-friendly disinfection methods for rice seed, we propose a rice seed disinfection method that uses steam heating. This method aims to sterilize the surface of rice seeds with wet heat using steam condensation, and to simplify the cooling and drying process compared with the conventional hot water treatment.<BR>To investigate the applicability of this method and determine the optimal conditions for rice seed disinfection, we examined the effects of heating air temperature, air humidity, air flow rate, and heating time on the sterilization rate and germination rate of rice seeds. We found that the optimal conditions were as follows : heating with an air temperature of 200°C, and wet bulb temperature of 80°C, a heating time of 2s, an air flow rate of 1.8m/s, and cooling by ventilation with ambient air for more than 60 s. Using these optimal conditions, the newly described disinfection method was as effective against blast and bacterial grain rot as the conventional hot water treatment.

    This paper presents the feasibility of solar thermal energy utilization to plant factory. Performance and operationcharacteristics of the solar driven absorption chiller heater of 352 kilowatt refrigeration capacity were investigated byusing long term demonstration test data of June 2009 to October 2013. Effects of solar insolation to the absorption chillerheater performance were examined by changes of air conditioning load ratio and solar position. As a result, it wasdemonstrated that the COP in case of parallel operation by solar energy and town gas becomes 20 to 50 percent higher thanthat case of another operation modes. Also, Seasonal performance of the system is calculated based on the appearancefrequency (weight) of the outdoor temperature. The air-conditioning load ratio was sorted out for every outdoortemperature based on the data measured during 5 seasons from 2009 to 2013 to obtain the averaged COP value. COP takesthe maximum value at the air-conditioning load ratio of 30% and decreased at both higher and lower ratios than that.

    In order to improve the utility of cooking ovens, we conducted heat transfer mechanism analyses of a convection/steam combined oven by focusing on steam condensation. Spherical wet gauzes were used as the sample material. The heat transfer mechanisms were analyzed by considering the heat balance on the surface of the spherical gauze using the measured mass change of the sample. the temperature change of the sample surface and gas flow. In this manner, we could estimate the heat flux in terms of heat transfer and heat flux changes with time. The estimated data were used to generate diagrams that visually depicted the heat transfer mechanisms in terms of heat flux changes with time. The diagrams provided to visually understand and compare each heat transfer quantity. incremental moisture content and heat quantity generated because of steam condensation on the sample material, as well as drying rates under different heating conditions. In addition, the heat transfer mechanism of a steam convection oven was analyzed using this method. We analyzed the effects of each setting condition (e.g., temperature, humidity. and velocity) on the heat flux, moisture content, and temperature of the sample material during heating. From the analysis results, it was possible to understand and compare the heating characteristics between oven types, and to set the proper conditions for achieving optimal oven heating.

    System performance prediction model for air-cooled air conditioner has been developed, and influences of Grooved tubes on performance of air conditioners with R410A were quantitatively investigated. Calculated results with simulation model correspond approximately to measured results by the authors and other researchers. After that, performances of air conditioners with grooved tubes were predicted. Results show that condensation heat transfer coefficients decrease with the rise of air conditioning load rate, and boiling heat transfer coefficients increase with the rise of air conditioning load rate. On the other hand, pressure drops increase 1.2-1.4 times in evaporator. Then, COPs of air conditioners with the grooved tube are 1.16 times higher than COP of air-conditioners with the smooth tube.

    A theoretical and experimental study is conducted to investigate the detached volume from the pendant drop on sphere surface. From the observation of droplet detachment by use of a high speed video camera, the movement of upper part from the neck of droplet is quite slow compared with that of detaching lower part. The surface profile of upper part was calculated approximately as a static problem by using the axi-symmetric Laplace equation. Using the droplet profile, the system energy was calculated including the work done by the solid-liquid wetting behavior. Based on the condition of energy minimum, the volume of upper part was determined among the solutions satisfying the boundary conditions and the volume of detached part V was calculated. The volume V increases with the sphere diameter and approaches to that for the plate. V is strongly dependent on the wettability between sphere and liquid, and decreases with the receding contact angle. The detached volume of water droplet was measured for spheres of porous brick with various diameters. The results agreed well with theoretical ones obtained in this study.

    The simple and noninvasive measuring methods of bioinstrumentation in humans is required for optimization of air conditioning and management of thermal environments, taking into consideration the individual specificity of the human body as well as the stress conditions affecting each. Changes in human blood circulation were induced with environmental factors such as heat, cold, exercise, mental stress, and so on. In this study, the physiological responses of human body to heat stress and exercise were investigated in the initial phase of the developmental research. We measured the body core and skin temperatures, skin blood flow, and pulse wave as the indices of the adaptation of the cardiovascular system. A laser Doppler skin blood flowmetry using an optical-sensor with a small portable data logger was employed for the measurement. These results reveal the heat-stress and exercise-induced circulatory responses, which are under the control of the sympathetic nerve system. Furthermore, it was suggested that the activity of the sympathetic nervous system could be evaluated from the signals of the pulse wave included in the signals derived from skin blood flow by means of heart rate variability assessments and detecting peak heights of velocity-plethysmogram.

    A novel simple measuring method of actual performance of room air-conditioners by neural net work analysis (NNW) has been developed. The actual performance for a long term which is difficult to be measured by air enthalpy method is able to be measured easily by this method. In other words, actual performance of room air-conditioners can be measured by the proposed NNW method without measurement of air flow at indoor unit and outdoor unit which changes due to clogging of heat exchanger by dust. In order to gather data for training and testing the proposed NNW method, the room air-conditioner for experiment was set up. Inputs to NNW are outdoor temperature, indoor temperature, indoor wet-bulb temperature, inlet temperature of evaporator, outlet temperature of evaporator, condensation temperature and power consumption. The output from NNW is COP. The COP by NNW method has mean errors under 2.8% in quasi-steady operation condition and has mean errors under 4.6% in unsteady operation condition, compared to the COP of air enthalpy method. Results show that the COP of air conditioners can be measured easily for a long term using NNW within a high degree of accuracy.

    Micro-scale distributed power generation system, which means a micro-cogeneration system in almost cases, has been paid a great attention from a standpoint of saving fossil fuels' consumption and preventing global warming. Especially, polymer electrolyte fuel cell (PEFC) is considered the most promising power generation system for small scale commercial use and residential use. In the PEFC cogeneration system, small amount of waste heat at low temperature from a cell stack is almost used to produce hot water. Therefore, in the paper, we proposed a new heat utilization method of the waste heat for air conditioning. In the proposed home cogeneration system, absorption refrigerator is introduced in order to produce chilled water. Thermal performances of the proposed system have been analyzed by a computer simulation which was developed for the prediction both of power generation characteristics of PEFC and absorption refrigerator's behavior.

    A simple method was proposed for estimating drying rate from the material temperature change in a drying process. This method was applied to convective and combined convective-conductive dryings of a thin glass-particle layer, i.e., non-hygroscopic porous slab, and to convective drying of a PVA solution film. The method was proved to be useful except for two cases; the period when the temperature rise of the drying material is not accompanied by moisture evaporation; and the period when the quantity of moisture evaporating is small with the change in material temperature is extremely small. The proposed method can be applied to estimate drying rate of a coated web in a rapid drying using hot air, where the conventional method of estimating drying rate from mass change data is difficult to apply.

    Split type air conditioners are operated actually in the situation unlike the condition that was described in a product catalog. On the other hand, exhaust heat from air conditioner is considered as one of the causes of heat island problem in urban area, and the air conditioner performance and heat load affect exhaust heat amount. In this study, air conditioner performances in both standard summer day and severe hot day were examined by dynamic simulation which considered outdoor weather changes. As a result, actual performances of the air conditioner were demonstrated as a function of outdoor temperature, heat load and indoor temperature. The higher the outdoor temperature and heat load rise, the smaller influences of indoor temperature against COP became. In standard summer day, relative performance exceeded by 15 to 45% than that of JIS operating condition. Also, COP in severe hot day decreased about 6% at the peak time than that of standard day. As a result, the air conditioner exhaust heat during one day which was predicted by the proposed simulation model became about 16% smaller than the conventional prediction model.

    Amaranth seeds have a high nutritional value, and predisposition for popping when heated under proper conditions, accompanied by evaporation of contained water. Popping can be an effective and beneficial method for food processing. In this study, regulation and measurement of moisture content and its relationship to the mechanical properties of the amaranth seed were investigated. The effect of initial moisture content and gas temperature on expansion ratio, seed shape and browning, using hot air and superheated steam as heating media with a special fluidized bed for popping, was also studied. As a result, the maximum volume of the samples after popping was 8.7 times higher than the raw samples' volume, provided that the initial moisture content of the raw samples was 0.15 kg/kg, using hot air at 260°C for 15 seconds. In the case of superheated steam, the optimum moisture content was slightly lower than that of hot air, and the expansion ratio was measurably lower because the seed coat was softened by initial steam condensation. The optimum condition for regulation of seed moisture content for popping was determined from the water sorption isotherm, with the optimum moisture content located just before the moisture content started to increase at a faster rate, with increasing relative humidity. The results of rheometer measurements showed that the degree of elasticity decreased and yield load was nearly constant when the moisture content was higher than the optimum value of 0.15.

    Drying by use of atmospheric superheated steam (SHS) as a drying medium has various characteristics: the materials to be dried are heated rapidly by steam condensation, they are sterilized and their oxidization at high temperature is reduced in comparison with that when air is used. Therefore this drying method is petentially applicable to food processing.<br>In this study, coloring of raw sliced potatoes during SHS drying and hot air drying at 170°C and 240°C under atmospheric pressure was investigated. The results showed that starch granules remained at the surface of the samples dried with hot air, but no starch granules remained after the SHS drying. The potato slices dried with SHS were found to be darker in color and to have a glossier surface. Starch gelatinization proceeded more rapidly in SHS drying, than in hot air drying, and amounts of low molecular weight carbohydrates and free amino acids produced, which are thought to contribute to coloring, were higher in SHS drying than in hot air drying.

    Effects of an addition of surfactant to a lithium bromide aqueous solution have been investigated experimentally. N-octanol was used as a surfactant. The Marangoni convection occurred at/beneath the solution surface in the very beginning of steam absorption was observed both by a real-time type laser holographic visualization and by temperature measurements with extremely fine gauge thermocouples. Generation and growth of the Marangoni convection were both observed and evaluated quantitatively by the flow visualization. Furthermore, solution's surface temperatures with and without addition of the surfactant were measured minutely. Cell's formation pattern and migration speed at the surface were measured varying the initial surfactant's concentration ranging from 0 to 50000 ppm and the shallow liquid layer thickness ranging from 2 to 5 mm. And spacio-temporal scales of the Marangoni convection were determined. Also solution temperature changes at the surface were compared. Temperature increases when the surfactant was added to its solubility limit became almost double than that case of no surfactant. From these temperature differences, effects of the surfactant on absorber's performances were estimated by a calculation quantitatively with diffusion coefficient as an evaluation value.

    This research was conducted in order to better identify the torque loss of a hermetic rotary compressor for one revolution, and to directly obtain the actual shaft power of the compressor. A testing compressor and a gas cycle type simplified calorimeter were developed for direct measurement of the compressor torque. <br> A strain gauge was stuck on the shaft between a compressor and a motor. Thus, the compressor torque could be measured directly by the strain gauge and data were transmitted to out of the compressor's vessel through a slip ring. Rotational speed of the compressor was measured by using a gap sensor also. From these measurement results, actual shaft power was calculated experimentally. <br>On the other hand, effective compressive torque for compressing refrigerant gas was predicted theoretically. From both experimental and theoretical results, torque loss of the compressor was determined as the difference of the compressor torque from the effective compressive torque. Consequently, a loss of over-compression could be revealed from the torque loss experimentally. Furthermore, overall adiabatic efficiencies of compressors obtained by the actual shaft power were 1.1&sim;3.5% higher than former overall adiabatic efficiencies obtained by the motor output.

    Absorption refrigerators available today are designed and commercialized on the basis of empirical technology. So the absorption phenomenon and heat transfer process in a conventional absorber of horizontal smooth tubes type have not been clarified yet. In the present study, a prototype experimental absorber which enables us to observe a falling film of aqueous lithium bromide on the tubes in its optically was manufactured. The absorber consists of 13 horizontal smooth tubes. And absorption experiments were carried out with a use of n-octanol as a surfactant ranging from 0 to 500ppm. Behaviors of a solution flow both on the horizontal tubes and in the space among them were observed by using a high speed video camera. Moreover, temperature distributions of the falling film of aqueous lithium bromide, cooling water and heat transfer tubes' surfaces were measured minutely. The ratios of wettability of tubes' surface were estimated, and heat transfer values on the absorber were evaluated. The refrigerating capacity increases to double with increasing surfactant concentration until its solubility limit .And it was revealed that the enhancement of refrigerating capacity with addition of the surfactant is mainly caused by a spread of wet surface of tubes.

    Surface tension induced (Marangoni-Benard) convection occurs at a surface of lithium bromide (LiBr) aqueous solution with addition of a small amount of surfactant was observed in order to investigate a mechanism of absorption enhancement by surfactant. Real time type laser holographic interferometry was used to visualize the transient phenomena occurred at/beneath the LiBr aqueous solution's surface in the very beginning(0-20msec) of steam absorption under vacuum condition(0.7kPa). Experiments were performed varying the initial surfactant concentration from 0 to 200ppm and the liquid layer thickness of 3-5mm. Pentagonal or hexagonal cell's patterns were observed at the surface clearly. And those cells evolved from small to large size instantly. Thereafter large scale chaotic eddies were induced at the surface.

    Local heat transfer characteristics of high temperature impinging two-dimensional air jets were investigated by using a novel multi-pulsed laser holographic interferometry. Thermal flow fields at nozzle-to-plate space were visualized real-time for various jet velocities and nozzle-to-plate distances, which were recorded by using a high-speed streak camera(5000fps). Instantaneous development and growth of streamwise vortices were clearly visualized by this novel method. The results indicate that the local heat transfer coefficients are greatly affected by the large-scale vortices which appear in the wall jet region. Furthermore, it could be demonstrated that this multi-pulsed laser holographic technique is effectively applicable to the high-speed observation of the impinging jets.

    Recently, the superheated steam is widely used in the various fields, for example, drying, sterilization and cooking. In the use of superheated steam, humidity in the processing device is one of the important parameter affecting product quality. So we need the humidity sensor whitch is economic and used at high temperature. To measure humidity at high temperature, it is necessary to control the water retention level of the wick. In this paper, we showed the principle of the moisture sensor and the structure of the humidity sensor. The result shows that it is possible to detect the water retention level by the partial moisturel sensor, and to control water retention level by the moisture sensor.

    We applied the theory of a psychrometer to develop a humidity monitoring system by using porous ceramics as a sensing element. The effects of porosities and pore size distributions on water transfer were investigated theoretically and experimentally. Several types of cylindrical porous ceramics were used. In addition, we compared the moisture transfer coefficients / permeability coefficients. The results showed that capillary water transfer were higher in the conditions that porosity was laeger and pore size distribution was wider. The water transfer by pressure difference were higher in the conditions that mode diameter was laeger.

    Recently, the superheated steam is widely used in the various fields, for example, drying, sterilization and cooking. In the use of superheated steam, humidity in the processing device is one of the important parameters affecting the product quality. Therefore, a new humidity sensor which can be used at high temperature is required to be developed. There is also a demand to monitor the distribution of humidity inside the processing device. So we develop a system that can monitor humidity measured in remote places at high temperature in real time. In this paper, we show structure of the system. It is confirmed that our system can measure humidity at high temperature and can monitor humidity data in real time.

    Recently, the superheated steam is widely used in the various fields, for example, drying, sterilization and cooking. In the use of superheated steam, humidity in the processing device is one of the important parameter affecting product quality. So we need the humidity sensor whitch is economic and used at high temperature. To measure humidity at high temperature, it is necessary to control the water retention level of the wick. In this paper, we showed the principle of the moisture sensor and the structure of the humidity sensor. The result shows that it is possible to detect the water retention level by the partial moisturel sensor, and to control water retention level by the moisture sensor.

    Recently, the use of superheated steam is expanding in the field of sterilization, drying, heating and cooking. In the use of superheated steam, humidity in the processing device is an important parameter affecting the product quality. And the needs of being able to monitor remotely in real time has increased. In this paper, we propose a remote measurement system using a wireless network, and showed its outline. We did experiment using 920MHz band and 2.4GHz band in actual environment for elucidating the propagation characteristics, if the data is send to outside from the steam convection oven's inside. The result shows that the both frequency bands can communicate without problems because electromagnetic wave leak to the outside through peep window.

    Nowadays, the temperature and humidity control of superheated steam have become important research area in food drier, pasteurization and food processing. The authors have studied on economic humidity sensor that it is available even at high temperature of more than 200 degrees. The humidity sensor works based on relationship between dry-bulb and wet-bulb temperatures. To measure accurate wet-bulb temperature, water retention control is necessary for keeping temperature near the thermocouple for wet-bulb uniform inside wet material. The sensor's structure should be also well-considered so as to be suitable for water supply functionality. In this paper, porous ceramic is newly developed and used as wet material of the humidity sensor because of high durability against high temperature environment. For automatic water retention control, a prototype of the sensor has a water level sensor inside ceramic and a moisture sensor on the surface of the ceramic. The microcontroller operates a pinch valve to control the amount of water from a tank based on the sensor's outputs. We propose its control algorithm and confirm its validity by transfer function analysis. Moreover, the prototype of the sensor is implemented on the food processing machine and an experimental evaluation of the water retention control is made. We also confirm that the moisture sensor on the surface of the ceramic is effective for detecting reliability of the wet-bulb temperature measurements, by additional experiments.

    A new molding method using high humidity hot air as heating media was developed. We constructed a laboratory-scale apparatus for concluding basic experimental studies. Packed beds of silica sand coated with/without phenol resins or sugars as an adhesive agent were used as the material. During the initial stage of heating with high humidity air, the temperature of the packed bed uniformly rises rapidly by steam condensation. Results of molding tests indicated that the relationship between the wall temperature of the heating section and the dew-point temperature of the heating media, for regulating the condensation in the packed bed, should be optimized to improve the quality of products and to reduce the heating time.

    The authors have been investigating about thermal utilization of the biomass resources in the city from the viewpoint of prevention of global warming. In this report, we examined high efficiency of the waste generation theoretically among a waste incineration plant and the sewage treatment plant where a waste biomass was concentrated. Specifically, we examined about two improvement methods. One way was a heating of the steam by means of a digestion gas which is generated through the sewerage treatment process. The other way is an introduction of binary cycle power generation by means of a working medium that has a low boiling temperature. As a result, it was revealed that the efficiency of incineration power generation is improved 8 percent at the maximum.

    Digestion gas that is generated by anaerobic digestion of wet biomass such as raw sludge and garbage consist of 40% CH_4 and 60% CO_2. At first, molten carbonate fuel cell running on the digestion gas was proposed and a simple prediction model about performance of MCFC cogeneration system was developed in order to examine the characteristics of the system. As results, it turned out generating efficiency of MCFC-CGS is about 42% when the stack operating temperature was 700 degree Celsius and its thermoelectric ratio could be set up according to the stack operating temperature. Next, 5 basic urban buildings model were developed in order to examine capability of innovating MCFC-CGS to those buildings. As results, it turned out that MCFC-CGS could purvey 100% thermal demands of hotel and public facility and generate over 0.5% of the digestion gas used as a fuel of MCFC-CGS at apartment house, office building and commerce facility.

    Solar energy use air-conditioning system has been attracting great attention from the view point of global wanning problem. In this paper, the performance of a solar-assisted absorption chiller heater of 352 kilowatt refrigeration capacity has been examined experimentally through a long series of proof examination of 17 months. Also, the analytical model of solar collector subsystem has been developed and the temperature changes at the collector outlet were calculated in order to investigate the performance theoretically. Solar radiation irradiance, temperatures at inlet and outlet of circulation water in three types of solar collector, collecting heat amount by the solar energy and town gas consumption rate were measured continuously every ten minute. From these measured data, both of the solar collector performances and the absorption chiller heater performance were calculated and the performance properties of the system against the solar radiation were revealed. Consequently, the amount of town gas consumption of the absorption chiller heater has been decreased about 13 percent through air-conditioning period. Also different characteristics of three types of solar collectors to the solar radiation were revealed quantitatively.

    A simple method is required for measuring humidity in a wide range of conditions from room air to superheated steam for several hours. In this study, we applied the theory of a psychrometer to develop a humidity monitoring system by using cylindrical porous ceramic media as a sensing element. This system contains a section for supplying/discharging water. We tested the performance of this system in terms of its measurement accuracy and response time. At a gas flow rate of 1 m/s and a gas temperature less than 310℃, the error of the steam mole fraction was observed to be less than 10%. In addition, a response time was reduced as a sensing element diameter was smaller. The system had a 90% response time of less than 60 s at a gas temperature of 200℃, a gas flow rate of 1 m/s, a flow rate of supplied water of 0.01 g/s and a water temperature of 25℃ when a sensing element diameter was 9mm.

    Micro scale gasifier of the biomass of waste origin, which are woody pellets, using the superheated steam as a heating medium has been developed and the feasibility of the generation pyrolysis gas as a fuel for micro cogeneration was verified. Thermal cracking experiments were conducted about woody pellets in the temperature range from 500 to 700 degree Celsius. Then, the gas generation rate, the calorific value and cold gas efficiency of the gas were measured. Next, Bio-MCFC-CGS which system is constructed from biomass pyrolysis gasification system and MCFC cogeneration system running on its biogas was proposed and a simple prediction model about performance of MCFC cogeneration system was developed in order to examine feasibilities of those pyrolysis gases as a fuel. As results, it was revealed that the calorific values of the pyrolysis gases are about 14 to 19 MJ/Nm^3, and become 1/3 to 1/2 than that of town gas(13A). Furthermore, it turned out that the power generation efficiencies become lower when those pyrolysis gases were used as a fuel. But, it turned out that the total efficiencies are almost same to the case of town gas also.

    We have developed a humidity sensor by applying the principle of the Assman psychrometer. Cylindrical porous ceramic material was used in this sensor for sensing humidity. Some water flowing in the center of the sensing element is supplied to the surface by means of capillary flow, and the temperature of the wetted surface is used as a wet-bulb temperature. In this study, the relationship between the water evaporation rate and the surface temperature of the humidity sensing element were experimentally and theoretically investigated under various gas temperature (100-300℃) and flow velocity (1-10 m/s) conditions. Three types of porous materials with different pore size distributions were used as the sensing element. The difference between the surface temperature and the calculated value of wet-bulb temperature was observed to be large when the evaporation rate was high and the porosity and the median diameter of the sensing element was low.

    Micro scale gasifier of biomass, which are refuse derived fuel and wood pellets, using the superheated steam has been developed and the feasibility of the generation pyrolysis gas as a fuel for micro co-generation was verified. The thermal cracking experiments were conducted at the superheated steam temperature from 500 to 700 degree C. The quantitative analysis of pyrolysis gases were carried out and residue amounts of char and tar were determined. Moisture and tar in the pyrolysis gas were removed by a cooling device which was kept at 0 degree C. The calorific values of the pyrolysis gases were about 14 to 19 MJ/Nm^3, and were 1/3 to 1/2 than that of town gas(13A). Then, the refined gas was supplied to a micro gas engine of 1 kW output as a fuel. The experiments were conducted repeatedly by changing the mixture ratio of pyrolysis gas and town gas. As a result, it turned out that the mixture of 13% of pyrolysis gas to the town gas is possible under keeping constant power output.

    A method for measuring a steam mole fraction at the temperature of around 80 - 300℃ and the steam mole fraction of hot air to superheated steam as the objects of heating devices for cooking, and so on, was considered in this study. The temperatures of spherical wet materials (brick and gauze) were measured in a flow system wherein the temperatures and humidity were regulated by heaters and by balancing the flow rate of steam and air, respectively. The steam mole fraction was calculated from the wet material temperatures by two methods, based on adiabatic saturated temperature and on heat and mass transfer model in boundary layer. These calculation results were in good agreement with the set values of the experimental flow conditions. The psychrometric chart for a wide temperature and humidity range including superheated steam was proposed as well. In addition, error factors of between the measured temperatures of wet material and the adiabatic saturated temperature were investigated.

    A steam convection oven can heat a large amount of food using steam generated from a small boiler. To measure the changes in the humidity of the gas in heating chamber, we set a wet spherical gauze in the chamber during heating with and without steam.In the case of heating with steam, the steam mole fraction of chamber reached 100% after approximately 3min, the material temperature increased faster, and lesser water evaporated than in the case of heating without steam. Furthermore, it is shown that the amount of food in the chamber is effected on the humidity increasing rate during heating without steam. We show that the humidity of the gas in oven chamber affects the material temperature, the mass of evaporated water, and the time required for heating, all of these facters are important for good cooking.

    The effect of dry- and wet-bulb temperatures on the drying time of a wet spherical porous material in high-temperature gas flow was investigated. The changes in the mass and surface and core temperatures of the material during drying were measured using a test apparatus, in which the dry- and wet-bulb temperatures could be controlled in the range of 120-280 and 40-100 ℃, respectively. A wet spherical brick was used as the sample porous material. The experimental results showed that the mean moisture content at the end of surface evaporation period (the critical moisture content) was low under high wet-bulb temperatures. Further, the standardized drying characteristics curves for falling drying rate periods were in good agreement with each other under all experimental conditions. In addition, the time required to reduce the moisture content below the critical moisture content was almost the same under all wet-bulb conditions at the same constant drying rate, regardless of steam condensation.

    Micro scale pelletized RDF (Refuse derived fuel) gasifier using the superheated steam as gasifying agent was developed and the feasibility of the syngas as fuel for micro co-generation was verified. The thermal cracking experiment of wood was conducted at 500 to 700 degrees C. Syngas was analyzed and char and tars content were determined and analyzed. Moisture and tar in syngas were removed by a cooling device kept at 0 degree C. The calorific value of syngas was about 14 MJ, and was about 1/3 of town gas. Then, refining gas was supplied as fuel of a micro gas engine of 1 kW of outputs. And the production of electricity using the micro gas engine was measured. It experimented by changing the mixture ratio of syngas and town gas. As a result, it turned out that the mixture ratio of syngas is 13% possible for rated operation. Moreover, it compared with the simulation result. Furthermore, it investigated theoretically also about the feasibility as fuel for molten carbonate fuel cell.

    Sprit type air conditioners are on the increase for large building because of easy installed. Increase in sprit type air conditioners had air cooled heat exchangers, for example multi-type packaged unit system, causes increase in amount of sensible exhaust heat generated when they are at work. The likely explanation that this is one of causes of heat island phenomena is being discussed. In this study, the method of prediction for multi-type packaged unit system performances was devised, and COP and amount of exhaust heat from multi-type packaged unit system during operation were predicted. As a result, the higher outdoor temperature, the lower COP became. COP difference between our prediction and a test operated Daikin Industries, Ltd., falls within 0.5% under the influences of outdoor temperature. On the other hand, exhaust heat from sprit type air conditioners during one day which was predicted in sever hot day was occurred about 11 % larger than in standard summer day.

    Micro scale RDF gasifier in which the superheated steam is used as gasifying agent was developed and the feasibility of the syngas as fuel for micro co-generation was verified. The thermal cracking experiment of RDF was conducted with the temperature range from 500 to 700 degrees C. Then the gasification experiments of the RDF were carried out with a bench scale reactor of the packed-bed type. Furthermore, the heat and mass transfer analysis model of the system was constructed and examined. From both the experimental and theoretical work, first, the pyrolysis characteristics of the RDF within the temperature range from 573 K to 853 K were revealed. Moreover, the production rates of pyrolysis gas under different experiment condition of superheated steam were determined and compared with the calculation results. And the ingredient of the pyrolysis gas was analyzed. After all, the pyrolysis gas which is generated from the RDF by thermal cracking was showed that it can fully use as gas fuel.

    Generally, the conditions of convective heating in equipments used for food processing, such as a dryer or an oven, varies slightly. For instance, in automatic regulation, door opening/closing can cause such fluctuations. In this study, the effect of flow conditions (temperature, humidity, and pressure under constant/nonconstant conditions) on the material temperature and drying rate is investigated by an experiment and a numerical study using an approximate model for heat and mass transfer. The results show that the change in the humidity of the drying media is affected strongly by the material temperature and drying rate. With in a few seconds of a decrease in the humidity, the evaporation rate increases temporarily under the experimental conditions of this study.

    The behavior of condensed water on the surface of a spherical porous material by direct contact condensation in the early stage of superheated steam/high humid hot air drying was investigated experimentally. A spherical brick was used as the sample porous material. The changes in the mass and surface and core temperatures of the material during drying were measured at various dry- and wet-bulb temperatures of the drying media, and various initial moisture contents of the material. From the experimental result, it was observed that the amount of condensate increased with a decrease in the dry-bulb temperature at high wet-bulb temperature or an increase in the wet-bulb temperature. The amount of one drop of condensate decreased at high wet-bulb temperature. Furthermore, when the initial moisture content of material was slightly lower than the maximum moisture content of the material, the total amount of drops was increased.

    Convective drying of glass beads packed beds containing NaCl aqueous solution, under a wide range of gas temperature and humidity (room air to superheated steam), and the relationship between surface salt deposition, material temperature and moisture content changes, was investigated. In the case of high gas temperature and low humidity, salt deposition was evenly distributed across the bed surface, and salt crystallization was observed to begin at high moisture content. Drying proceeded over two stages of distinctly different drying rates. At high humidity, salt crystallization was observed to begin at lower moisture content, and was unevenly distributed across the bed surface.

    In recent years, urban areas have been experiencing a rise in the regional atmospheric temperature because of heat island phenomenon, which increases the summer heat. One of the causes of that is an exhaust heat from air-conditioners. In this paper, we analyze dynamic characteristics of a split type air-conditioner's operation taking into consideration thermal loads to be able to get closer to the real operation. Also, we survey the deterioration in the performance of these air-conditioners and the increase of exhaust heat from them ascribable to the temperature rise caused by the heat island phenomenon. As a result, dynamic characteristics of a split type air-conditioner's operations are grasped by controlling compressor's frequency In addition, COP and amount of exhaust heat in practice operation are simulated to examine influences of indoor setting temperature and air flow rate of outdoor unit.

    The effects of wet-bulb temperature of drying media and material's pore diameter on drying characteristics and time were investigated experimentally. Glass bead (mean diameters of 110 and 400μm) packed beds which contained pure water or NaCl aqueous solution were used as porous sample material. The material mass and temperature changes were measured and the surface condition changes by salt crystallization were observed during drying. From these results, in cases where water was contained, the wet-bulb temperature was lower, the drying time was shorter. In cases where NaCI aqueous solution was contained, the wet-bulb temperature was lower, the drying time was longer and the material surface was covered with crystallized salt evenly distributed with glass beads with a mean diameter of 110μm.

    Drying of porous material containing a low boiling point solvent in high humidity air was investigated. Glass beads (mean diameter 50μm) packed beds which contained ethanol or water were used as model material. Mass and surface temperature of the material was measured during drying. In case of material containing ethanol, determinable mass increase was not measured even when the material temperature was lower than the steam dew point temperature of drying media at the early stage. The reason is that the ethanol evaporation from the material occurred simultaneously with steam condensation from the drying media onto the material surface.

    The greatly changes of the human circulation dynamics induced by heat, cold, exercise and mental stress or postural change, etc. as environmental factors were known well. To determine the human adaptability by cardiovascular system measurement using an optical-sensor, a small and portable data logger, in which high-speed sampling measurement by 2.56kHz throughout 14 hours continuously was possible, was developed in this study. In addition, we measured the both of skin blood flow and pulse wave as the index of the adaptation of circulatory system to the heat stress and exercise. These results suggested that the sympathetic nerve system as the human circulatory response was able to be evaluated from the signals of the pulse wave included in the signal of skin blood flow.

Glass beads (mean diameters of 110, 400 and 800μ m) packed beds which contained pure water; sucrose; NaCl; mixed(sucrose and NaCl) aqueous solution were used as porous sample material. From these results, the smaller pore diameters and the lower wet-bulb temperature caused the sucrose contained near the surface to increase. The sucrose distribution in the material was effected, but almost all of amount of NaCl remained at the surface of the material in every experimental condition excluding the mixed solution. In case of the mixed solution, the amount of sucrose contained near the surface after drying was increased by higher NaCl concentration.

    A novel home cogeneration system that is available to air conditioning use has been proposed, and its feasibility has been investigated theoretically. Waste heat from PEFC that is used as a generator is usually utilized as a hot water in micro cogeneration. But, in Japan, in order to reduce increasing power consumption for air conditioning in residential use, it is indispensable to develop a home cogeneration system that can be used for air conditioning. Therefore, a single effect absorption chiller heater was adopted as waste heat recovery equipment. The absorption chiller heater is driven by the low temperature waste heat from the PEFC and is available for air conditioning. Their performances and efficiencies were predicted quantitatively by computer simulation. Furthermore, air conditioning performances of the absorption chiller heater were calculated with considering real weather conditions and were cleared for cooling water temperature changes.

    Effect of gas humidity and high voltage electrical field (HVEF) on evaporation rate were investigated. A pin type electrode was fixed above the water surface. Mass and temperature changes of water were measured under a continuous current electrical field and with parallel gas flow to the water surface. The experimental results showed that evaporation was enhanced with HVEF, gas humidity increased, evaporation rate was decreased but rate of evaporation acceleration by HVEF was increased. Water temperature reached a level approximate to wet-bulb temperature when HVEF wasn't used. Using HVEF, water temperature reached a lower than that without HVEF reading in the low humidity test, and reached a higher reading in the high humidity test.

    Recently, there has been a need for effective use of low temperature exhaust heat. So, we have suggested the intermittent suction dryer which can use low temperature exhaust heat (steam of latm or water of less than 100℃) as a heat source and use steam condensation in an auxiliary vacuum tank for reducing chamber pressure intermittently. Heat and mass transport mechanism in material to be dried under intermittently reducing pressure, and the utility of intermittent suction effect were investigated experimentally. Used coffee grounds were used as the material to be dried, both the temperature and moisture content distributions were measured. The heat flux from heat source to sample was also measured. From these results, it was shown that water in the area of greater than saturation temperature evaporated rapidly under intermittently reducing pressure and some vapor condensed in the area of less than saturation temperature. Evaporation became rapid at intermittent reducing pressure.

    Drying of potato starch paste in hot air, high humid air and superheated steam was examined. Initial moisture content was 0.92kg/kg-d.b., wet bulb temperature of gas flow ranged from 48℃ to 100℃, and gas temperature was 160℃. Temperature and moisture content changes of samples during drying were measured, and cross sections of samples were observed by SEM. The property of dried starch was strongly affected by wet bulb temperature - gelatinization effectively occurred only at higher temperature with water. In addition, the initial condensation/evaporation process in high humid air treatment, based on temperature and moisture content changes, was modeled as reverse process - an important process for material properties for drying.

    Effect of wet-bulb temperature on a drying rate of porous material containing water or sugar aqua solution in high-temperature (160℃) gas flow was investigated experimentally. Glass beads were used as the sample porous material. Mass and surface temperature changes of the sample during drying were measured with a test apparatus, in which wet-bulb temperature could be controlled from 48℃ to 100℃. From these results, it was shown that when the wet-bulb temperature was higher, the drying rate was smaller and the distribution of local sugar concentration was more even in this experiment. Whereas the water in the sample maintained a constant drying rate, the sucrose solution's drying rate decreased gradually after drying was commenced.

    A novel home cogeneration system that is available to air conditioning use has been proposed, and its feasibility has been investigated theoretically. Waste heat from the PEFC is usually utilized as a hot water in micro cogeneration. But, in Japan, in order to reduce increasing power consumption for air conditioning in residential use, it is indispensable to develop a home cogeneration system that can be used for air conditioning. Therefore, a single effect absorption chiller heater was adopted as waste heat recovery equipment. The absorption chiller heater is driven by the low temperature waste heat of the PEFC and is available for air conditioning. Their performances and efficiencies were predicted quantitatively by computer simulation. Total efficiency of the system reached about 80 % when the waste heat is recovered only as a hot water. But the total efficiency decreased with an increase of waste heat use for the purpose of air conditioning.

    Feasibility of a solar-wind hybrid power generation system in an urban coastal area, in order to construct an environmental symbiotic maritime city, has been investigated by an actual measurement. The research site is situated at Omaehama in Nishinomiya. The solar-wind hybrid power generation system is composed of two solar cells of 128W, two wind turbines of 450W, power controller, DC to AC inverter, and data acquisition unit. The solar cell output and wind turbine output were measured every fifteen minutes. Although the rated power generation of the wind turbine was larger than that of the solar panel, the generated electric power by the PV was larger than that of the wind turbine. The amount of power generation by the solar cell was almost proportional to the quantity of solar insolation. On the other hand, the amount of power generation by the wind turbine did not increase proportionally to the velocity of the wind and has been greatly influenced by the cut-in velocity of the wind turbine.

    A new approximated expression for non-isobaric unidirectional gas transfer caused by molecular diffusion, viscous and Knudsen flow has been formulated. The new approximated expression is a combination of the unidirectional isobaric diffusion equation within free space and the Darcy flow equation. The equations were derived from strict equations for one-dimensional binary component isothermal gas transfer within porous media that was modeled by the parallel pore model. It was shown that the calculation results, calculated by strict equations and by approximated equations, were in agreement. In addition, the temperature and pressure, at the inner evaporative surface of the porous material during drying in hot humid air, were predicted by the new approximated expression, and the effect of air humidity on material temperature was investigated.

    The characteristics of reverse process on parallel flow of high-humid hot air were investigated by numerical study. The mass and temperature of material during the treatment process were calculated by a one-dimensional plate non-steady heat transfer model with water as a treatment material. Murray-Landis I method was used for the moving boundary problem. As a result, it was shown that restoration time"-"the time material's mass return to initial mass"-"increases uniformly as humidity of hot air or thickness of material increases, and it decreases uniformly as heat flux from hot air or initial temperature of material increases. Moreover temperatures at the center of material at restoration time were predicted in several gas temperatures, humidities and material thicknesses. And the method to determine the best conditions of temperature and humidity of hot air for heating the material, without either drying or wetting, was shown.

    Effect of dry-bulb and wet-bulb temperature on the drying time of spherical porous material in high temperature gas flow was investigated experimentally. Mass and center of material temperature changes of material during drying were measured with a test apparatus, in which dry-bulb and wet-bulb temperature could be controlled. Spherical red brick was used as the sample porous material (15mm in diameter, 0.235 kg-water/kg-dry at initial moisture content). From these results, it was shown that the moisture content of each condition achieved the same reading at same elapsed time for the condition of high dry-bulb temperature"-"regardless of steam condensation at early stage of drying. Because, critical moisture content was lower, as wet-bulb temperature was increased, and the differences of drying rate during constant rate period were smaller.

    Dynamic behaviors of Marangoni convection induced at LiBr aqueous solution by addition of a surfactant have been investigated experimentally by using a real-time type laser holographic visualization system. N-octanol was used as a surfactant. The Marangoni convections occurred at/beneath the solution surface in the very beginning of steam absorption were observed in three dimensions. At first, vertical convective motions induced in the LiBr aqueous solution by addition of the surfactant were observed varying the initial surfactant's concentration ranging from 0 to 50000ppm and the liquid layer thickness ranging from 5 to 25mm. And, horizontal convective motions induced at the LiBr aqueous solution by addition of the surfactant were observed varying the initial surfactant's concentration ranging from 0 to 400ppm and the shallow liquid layer thickness ranging from 2 to 5mm. Pentagonal or hexagonal cell patterns were clearly observed at the surface and these cells instantly grew in size from small to large during the 10 milliseconds after the beginning of absorption. Thus, generation and growth processes of the Marangoni convection were revealed from the visualization results. And, spatial-temporal scales of the Marangoni convection were determined experimentally.

    Influences of a surfactant on performance of a novel plate type absorber have been investigated experimentally. Experiments were conducted on the vertical flat plate type absorber for absorption refrigerator/chiller, with changing surfactant's concentration. Surfactant(n-octanol) concentration was varied in the range of 0〜100ppm. Temperatures of LiBr aqueous solution, cooling water and heat transfer surface were measured minutely. Furthermore, flow conditions of LiBr aqueous solution were continuously observed optically by using a high-speed video camera. Refrigerating capacities were calculated from those measurement results. Results showed that absorber performances were significantly enhanced with increase of surfactant concentration. In case of surfactant concentration is 100ppm, absorber performance became about double than that case of no surfactant. Also, many protuberant "ropey" flows of LiBr aqueous solution were observed at upper region in the plate. These ropey flows swung side to side horizontally with a frequency of about 10 hertz. Consequently, it has been confirmed that those improvement were caused by the occurrence of Marangoni convection in the solution flow when the surfactant was added.

    The analysis, which takes into consideration a condensation of superheated steam in the early stage of superheated steam drying, had hardly been done. We made a test apparatus for measuring a mass change of dried material in superheated steam drying and in air drying. In this study, we measured the drying rates and compared the characteristic drying curves of superheated steam drying with that of air drying. Next we calculated constant drying rates for several Reynolds numbers. From calculation results, we found an inversion point temperature became about 350℃.

    Heat transfer characteristics of non-isothermal two-dimensional impinging hot air jet were investigated experimentally with multiple nozzles. Average and local heat transfer coefficients between an impingement plate and two-dimensional impinging hot air jet were measured by using thermocouples mounted in a heat transfer block. The parameters studied were nozzle-to-impingement plate distance (H/B=2,4,6,8,10), jet velocity (U_J=11m/s,22 m/s,28m/s), and jet temperature (t_j=50℃,100℃,150℃). From the results, it was found that influences both of jet velocities and jet temperatures on local Nusselt numbers. Also it was cleared that the high heat transfer coefficients were kept in case of multiple nozzles than that of single nozzle.

    Effects of a surfactant on performance of absorbers have been investigated experimentally. Experiments were conducted on three types of absorber, that are horizontal bear tube type and vertical plate type absorbers for absorption refrigerator/chiller, air-cooled vertical tube type absorber for heat transformer, with changing surfactant's concentration. Surfactant (n-octanol) concentration was varied in the range of 0&acd;250ppm. Temperatures of solution, coolant (water or air) and heat transfer surface were measured minutely. Furthermore, in case of the absorption refrigerator, flow conditions of LiBr aqueous solution were continuously observed optically. Refrigerating capacities and heat transfer rate to air were determined from those measurement results. Results showed that absorber performances were significantly improved with increase of surfactant concentration. In case of the absorption refrigerator/chiller, absorber performances became about double than that case of no surfactant. On the contrary, absorber performance increased only 15% in case of the heat transformer. Also, it has been confirmed that those improvement were caused by the occurrence of Marangoni convection in the solution flow when the surfactant was added.
