蓄热蒸发型空气源热泵实验研究
Experimental study on heat storage-evaporator air-source heat pump in low temperature environment
摘要：
设计了一种带相变蓄热器的空气源热泵机组样机，并进行了实验研究和性能分析。该机组有3种运行模式：蓄热模式、放热模式、除霜模式。测试结果显示，在室外环境温度低至-30 ℃时，系统COP可达1.94，制冷量能够满足寒冷地区热用户的热量需求，压缩机排气温度为105 ℃。

Abstract：
Develops a prototype of the air source heat pump system with the phase change heat storage, and performs the experimental study and performance analyses of the prototype. The unit can operate in three modes of heat charge, heat discharge and defrosting. The test results show that the heating COP of the system is 1.94 and the heating capacity can meet the heating needs of consumers even in the ultra-low -30 ℃ temperature environment, the exhaust gas temperature from the compressor is 105 ℃.
