Abstract :
The dynamic mathematical model of cool storage air conditioning system is established by method of mechanism modeling, and the refrigeration system model and cool storage tank model are coupled by mass conservation and energy conservation. Effects of flow rate of secondary refrigerant and evaporator inlet temperature on the system operation were studied. The supplying law of air conditioning cold energy was obtained. The results show that the greater flow of water is, the faster regenerator outlet temperature rises, and earlier the PCM in storage tank will reach phase change stage, and the best inlet temperature of evaporator is 12°C.
