中文摘要：
文章搭建了热管式太阳能PV/T热泵系统的实验装置,并根据实验装置建立了系统的数学模型,通过实验测试对数学模型进行了验证。研究了系统的热效率、电效率和COP等主要性能参数在全天的变化规律,分析了系统COP偏低的原因和改进措施。结果表明,在测试工况下,日平均热效率为35.4%,日平均电效率为11.0%,日平均COP为2.77,实验值与模拟值的误差均在±15%以内。该研究为热管式太阳能PV/T热泵系统的设计优化与性能研究提供了参考。
英文摘要：
The testing rig of heat-pipe PV/T heat pump system was constructed and the mathematical model was established according the testing rig. The mathematical model was verified by experimental test. Then the diurnal variation tendencies of thermal efficiency,electrical efficiency and COP were researched, and the reason for lower COP was analyzed. The results showed as follows：the daily average thermal efficiency was 35.4%,the daily average electrical efficiency was 11.0%,and the daily average COP was 2.77; the relative error between experimental and simulative values was within ±15%. This study provided reference for the design optimization and performance study of heat-pipe PV/T heat pump system.
