不同气候特征下空气源热泵高效应用策略探讨

Discussion on efficient application strategies of air-source heat pumps under different climatic characteristics

针对不同气候区的气候特点,分别提出了数种可行的空气源热泵应用方式,并以燃气锅炉+冷水机组作为基准方案,从初投资、运行能耗、运行费用和碳排放4个维度进行了对比分析。结果表明:空气源热泵在各气候区应用都具备一定的节能潜力,热泵效率越高,节能、降碳及节费的效益越好;夏热冬冷地区和寒冷地区制冷是主要矛盾,热泵应用时应重点关注供冷工况的能效;随着电力结构的变革,热泵应用的减排性能将逐步提高。

According to the climatic characteristics of different climate zones,several feasible application methods of air-source heat pumps are proposed respectively.Taking the gas boiler plus chiller scheme as the benchmark scheme,a comparative analysis is carried out from four aspects of initial investment,operation energy consumption,operation costs and carbon emissions.The results show that the application of air-source heat pumps in each climate zone has a certain energy saving potential.The higher the efficiency of heat pump,the better the benefits of energy saving,carbon reduction and cost saving.Cooling in hot summer and cold winter zone and cold zone is the main contradiction,so the heat pump applications should focus on the energy efficiency of cooling conditions.With the change of power structure,the emission reduction capability of heat pump application will be gradually improved.
