摘要(Abstract):

对太阳能热泵系统运行中压缩机的性能以及系统整体的运行性能进行了试验研究。试验结果表明蒸发温度和冷凝温度对于两者有很大的影响,蒸发温度越高,其制热性能越好,蒸发温度每提高4℃,系统制热量可以升高0.6~1kW。系统的制热水的出水温度达到了55℃,满足冬季的制热需求。系统的平均COP值达到4.1。
The compressor performance and overall performance of solar heat pump system were studied.According to the analysis,the evaporating temperature and condensation temperature had a great influence on both.It showed that the higher the evaporation temperature was,the better the performance of its heating was.The system heat capacity can be increased 0.61kW with each increase of evaporating temperature by 4℃.The temperature of hot water could reach 55 ℃,which could meet the demand of winter heating.The average COP of the system can reach 4.1.
