摘要(Abstract):

在焓差法空调器性能测试平台上,对空气源热泵热水器分别用R134 a、R417 a和R22进行各种典型工况下的试验,对3种制冷工质的吸排气压力、吸排气温度、压缩机输入功率、制热量、性能系数进行对比分析,分析验证了各参数随环境工况变化的关系,得出了在不同工况下的各特性参数的变化规律,为热泵热水器的设计及工质选用提供了参考。
A variety of typical experiments are carried out on the air resource heat pump water heater using R134a,R417a,and R22 under different operating conditions.Suction and discharge pressure,suction and discharge temperature,compressor input power,thermal coefficient of performance has been analyzed.The validation of various parameters and the trend with the the changing of the environmental conditions are obtained.It provides the references for the design and the refrigerant selection of the heat pump water heater.
