摘　　要：为解决家用太阳能热水器供热的间歇性和不稳定性,应用热泵辅助可达到全天候供热,该文通过对这种联合供热系统的供热性能和运行性能进行了测试,并对热水器的升温、保温和热泵的加热进行了试验和分析,结果表明:空气源热泵辅助型真空管家用太阳热水系统仅在累积太阳辐照量小于14 MJ/m2时,需要空气源热泵辅助加热,总制热性能系数可达6.18。To solve the problems of heating intermittent and instability for household solar water heater,application of heat pump for evacuated tube solar water heater system can achieved auxiliary heat supply round-the-clock.Heating performance test and operation of the system were conducted and the temperature rise performance,heat preservation of the solar water heater system and the heating performance of heat pump were tested and analyzed in this paper.The result showed that when the solar radiation was less than 14 MJ/m2,the system needed heating by air source heat pump,on this occasion,the system total coefficient of performance could reach 6.18.
