In order to provide theory basis to the consumers about installing refrigeration system for PV power

the cost recovery of refrigeration system for PV power was studied. This paper makes the air-conditioning system of an office building was transformed

the solar photovoltaic air-cooling refrigeration system based on the conditions of eastern Yanjiao area of Beijing

the solar photovoltaic air-cooling refrigeration system is solar cells convert solar energy into electrical energy

and then use electrical energy to drive a traditional chiller for cooling. Through calculation

the cooling capacity of the chiller

the number of series and parallel of photovoltaic modules and the model of the inverter are obtained. Combining the national subsidy policy for photovoltaic applications and the subsidy policy in Beijing

discuss the payback period of the system. The results show that if the photovoltaic air-conditioning refrigeration system is subsidized by the state

the annual subsidy for the first five years is 20 571.84 yuan

and the annual subsidy for the next five years is 12 200.24 yuan. The investment payback period is 12 years

which is economical and environmentally friendly.
