摘　　要：提出了一种复合热源太阳能热泵供热系统,通过阀门切换,可根据不同的天气状况改变运行模式,以空气和太阳辐射作为热源制取供暖用水。针对所设计的10kW供热系统,建立了系统的数学模型,对热泵串联集热器(SC+HP)及集热器串联热泵(H+SC)两种运行模式下的循环性能进行了计算机模拟分析,并计算了系统的全年运行状况。从模拟结果可以看出,在模拟进水温度区间内,HP+SC模式下热泵COP较高,最高比SC+HP模式高2.58%;而SC+HP模式集热器热性能较好,总热效率更高,最高比HP+SC模式高2.62%。A compound solar heat pump heat supply system was presented. The system can make heating water from air source and solar radiation by valve switching, based on different weather conditions. A numerical model for a 10kW heating utilizing was established. The circulation performances of solar collector with heat pump（SC ＋ HP） and heat pump with solar collector（HP＋ SC） operation modes were simulated. The all year round operation status was also caculated. The results have shown that the COP of HP ＋ SC mode is at most 2.58 % higher than SC ＋ HP mode in simulation water temperature range. But the latter has a better collector thermal performance and overall thermal efficiency is at most 2.62 % higher than the former.
