For the shortcoming of single air source heat pump, single solar energy heat pump and switch solar-air dual heat source heat pumps, a new solar air two source heat pump was proposed. Then, the performance of the solar air two sources heat pump was studied by experiment. According to the characteristics of heating performance of the solar air two sources heat pump, two important concepts were proposed. The two concepts were the two heat sources effectively compound heat transfer temperature difference and the max two heat sources effectively compound heat transfer temperature difference. And in this paper, the influence on the heating performance of the two heat sources effectively compound heat transfer temperature difference in different solar hot water flows, and the effect of the two heat sources effectively compound heat transfer temperature difference were researched by experiment and analyzed. The experimental results show, the max two heat sources effectively compound heat transfer temperature difference increased with solar hot water flow decreasing and it decreased with the outdoor air temperature increasing. The solar hot water flow has more influence than the outdoor air flow. (C) 2011 Published by Elsevier Ltd.
