中文摘要	分别针对单级压缩、双级增焓压缩转子式低温空气源热泵机组,进行了制热工况性能对比测试。测试结果表明,电辅热关闭时,双级压缩低温空气源热泵机组的COP比单级压缩机组提高22%~40%左右。可见,双级压缩低温空气源热泵制热性能比单级压缩热泵机组有较大提高,是一种经济性较好的辅助热源,可作为我国北方寒冷地区村镇住宅供暖采用清洁能源加低温空气源热泵补热系统的较优组合方案。; Comparative tests of heating performance were conducted on single stage compression and double stage enthalpy-added compression rotor low-temperature air source heat pump units. The results showed that,coefficient of heating performance( COP) of the double stage compression low-temperature air source heat pump units was about 22% ~ 40% higher than that of single compression units when the electric auxiliary heating was turn off.Therefore,heating performance of double stage compression air source heat pump units are largely improved,comparing with single compression units. Double stage compression units can act as a good subsidiary energy source. They can be taken as a better combined scheme of clean energy plus low-temperature air source heat pump for space heating of rural house in the cold region of northern China.
