本文对北方部分地区冬季平均温度相对较低的情况，设计了变频双级增焓压缩机空气-水热泵，对不同采暖供水温度下的性能进行验证分析，并与普通变频压缩机热泵机组的性能进行对比分析；结果表明，采用低温双级增焓压缩机的热泵机组在相同的性能下能效大幅提升，同时机组适用范围（包括出水温度以及环境范围）也大幅提升。

Considered the low average temperature in some areas in winter in North-China, this paper studies air source heat pump with variable-frequency 2-stage enthalpy-adding compressor. Research and analysis is made re-garding its performance in various heating ways and performance comparison with common inverter compressors. Re-sults suggest that energy efficiency of heat pump units using low-temp 2-stage enthalpy-adding compressor is greatly improved under the same performance and units are applicable to a much wider range (including leaving water temp and operating ambient).
