Summary

Aiming at the users of home, office, and other residential air conditioner users, this thesis puts forward a type of residential ice-on-coil storage air conditioning system. Through experiments, the thesis got the laws of the heat charging characteristics influenced by the initial temperature of the tank and the evaporation temperature of refrigerant, and the heat discharging characteristics influenced by the temperature of the return water and the rate of flow of the cycle water. Furthermore, the temperature distribution of the tank and the changing features of heat charging and discharging characteristics were concluded at different running stages. The results show that the chief influence factor of heat charging processes is the evaporation temperature of refrigerant. The best heat charging performance appeared when the evaporation temperature of refrigeration was set at -10°C. During the heat discharging process, the time of the temperature of chilled water supplied that was lower than 5°C is more than 61% of the whole heat discharging time.
