摘　　要：本文建立了利用中高温热泵作为辅助方式的太阳能三联供实验系统,开发了基于触摸屏操作的系统数据采集及运行监控系统(SCADA),并进行了采暖性能实验。结果表明,在12月份每天10:00￣14:00范围内,太阳能可以单独进行采暖,其它时间需要辅助,高温水箱在正常运行时温度一般都维持在45℃左右,12月份实验系统的太阳能保证率为64.6%。在3月份太阳能一天的蓄热量可以达到83.5kWh,热泵工作的性能系数为4.21。A solar experiment system combined cooling, heating and hot water supply assisted by moderate and high temperature heat pump was established, a computer supervisory control and data acquisition（ SCADA ）system was developed, experiments on the solar heating were carried out and operated characteristics were summarized. The results show that solar energy can supply heating lonely every moment between10;00-14：00 in December, otherwise need supplementary energy;the temperature of the high-temperature water tank was contained about 45℃, solar fraction was 64.6%. While the amount of heat storage one day was 83.5kWh in March, the COP of the heat pump was 4.21.
