英文要約The purpose is to improve the interior environment by developing a desiccant system and constructing operational and control technology for air conditioning systems under non-CFC conditions to actively monitor and regulate the temperature and humidity in the room.[Content and results](1) Development of regeneration method for an adsorbent using the magnetron method: A microwave heating regeneration experiment using testing equipment for the evaluation was conducted to collect basic data on the effect of irradiation power, irradiation period and timing, and processing airflow on adsorption behavior. The results showed that regeneration efficiency of 27.1% was achieved. The simulation results were confirmed as representing the results of experiments, and this was incorporated into the design of the prototype. (2) Development of high-speed regenerative hygrostat:Measurement of the adsorption isotherm of the candidate adsorbent, measurement of thermal and mass transfer coefficients, and evaluation of adsorption/desorption characteristics. Sensitivity of the desiccant section using the adsorption/desorption simulator was analyzed for the design of the prototype machine. (3) Development of high efficiency heat storage type heat exchanger:The grain size of the heat storage medium, material, superficial velocity, temperature efficiency, pressure drop, and sensitivity of the heat storage and release cycle were analyzed using a non-steady state sensible heat storage simulator developed for continuous batch operation, and the specific heat storage medium was selected. The heat storage simulator accurately represented the actual measurement. (4) Development of compact regenerative ventilation air conditioning system:The prototype system was designed on the basis of the several simulation and experimental results. The method of determining the seasonal energy consumption of the developed system was established by referencing the meteorological conditions in the Tokyo area based on the standards for determination of APF of the air conditioner. (5) Development of energy-saving comfort control technology and system operation:Confirmation was made that a higher average air conditioning temperature while maintaining comfort was attained by active control of interior conditions under constant absolute humidity. In addition, power consumption by the air conditioning unit for constant temperature operation and active adjustment operation at the average temperature remained at the same level.
