Abstract
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.
