Experimental research on performance of air-source heat pumps
摘要：
通过设计并建立空气源热泵系统实验台和系统测量设备，在不同运行工况下进行了实验研究，分析了冷凝器入口水温与冷凝温度对系统换热量、制热量、压缩机状态及系统COP的影响。结果表明，蒸发器进风温度为9.3 ℃、冷凝器入口水温为26～45 ℃时，系统COP最高可达3.4。

Abstract：
Through establishing test rig and measuring equipment for air-source heat pump systems, conducts the experiments under different conditions. Analyses the influence of the inlet water temperature of condenser and condensation temperature on heat exchange capacity, heating capacity, compressor conditions and system COP. The results show that system COP can reach 3.4 when inlet air temperature of evaporator is fixed at 9.3 ℃ and condenser inlet water temperature is controlled between 26 ℃ and 45 ℃.
