双级增焓空气-水热泵应用于欧洲采暖的节能性验证分析

Research and Analysis on the Application of 2-stage Enthalpy-Adding Air to Water Heat Pump in European Heating

本文对欧洲不同采暖方式以及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;

In view of different heating ways in Europe and the fact that average temperature in some areas in winter is relatively low,air source heat pump with variable- frequency 2- stage enthalpy- adding compressor is designed. Research and analysis is made regarding its performance in various heating ways and the performance comparison with common inverter compressors. Results 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 ambients
