Abstract
In order to satisfy the refrigeration requirements in modern society from the energy-saving perspective, this paper studies the ice storage air conditioning system driven by solar photovoltaic system. To this end, the methods such as analysis, comparison, and experimentation were adopted. The results show: the maximum of photovoltaic array photoelectric conversion efficiency was 17.58%, the maximum COP of refrigerating unit was 0.51, and the ice making capacity for 8 hours in the daytime 16.98kg, to ensure the cold supply inside the 10m2 room for 4 hours at night. Then the research results were further analysed. Finally, it is concluded that the ice-making process in the ice-flake sliding form causes a larger energy waste, therefore, the immersion-type static ice system by changing the disc evaporator into coiled tubular evaporator could increase the COP power by 40%.
