Abstract

The paper studied the running characteristics of air-source heat pump assisted solar water heating system. The results showed that the temperature of hot water could reach 32 , 42 and 57 respectively, when the daily total radiation was 9.79 MJ/m2 15.58 MJ/m2 and 21.42 MJ/m2. Under the radiation of 15.58 MJ/m2, heating 200 L water up to 55 , the power consumption of the system was 0.76 kW-h less than 0 MJ/m2, the coefficient of performance (COP) increased by 40%. Compared to other auxiliary heat, the system consumed minimum power, the payback period of investment was about 4 years.
