摘　　要：本文进行了以HFC125为工质的高温热泵热力性能的实验研究,分析了有、无回热循环工况下,冷凝器不同流程布置形式对系统COP的影响。实验结果表明:无回热循环情况下,冷凝器串并联混合布置形式具有较好的效果,系统COP实测均值达3.0,且和理论值接近度达80%以上。本文研究结果为高温热泵系统的性能优化提供了依据。In this paper,experimental study on the performance of high temperature heat pump （HTHP） system using HFC125 as refrigerant was performed, and the influences of different refrigerant circuitries with and without regeneration cycle on COP were analyzed. The results indicated that the series-parallel arrangement of condenser without regeneration cycle was better than other conditions,the measured COP was up to 3.0,and over 80% proximity to the theoretical value. The findings of this paper would provide reference for performance optimization of HTHP system.
