采用替代工质的空气源热泵性能试验研究
Experimental study on performance of air source heat pumps with alternative refrigerants
摘要：
测试了热泵系统在典型空调工况下采用R22的替代工质R134a，R404A，R407C时的制热量、功耗和COP。结果表明R407C的性能与R22比较接近，是R22比较理想的替代工质。

Abstract：
Tests the heat output，power consumption and COP of an air source heat pump system with the alternative refrigerants of R134a，R404A and R407C under typical air conditioning conditions.The results show that the performance of R407C is closer to that of R22 and it is the best alternative refrigerant for R22 in air source heat pumps.
Keywords:alternative refrigerant， air source heat pump， heat output， COP， power consumption
