摘　　要：“双碳”目标要求2030年达到碳达峰。供热与供冷能耗占据着碳排放的较大比例。热泵技术是实现节能减排的有效技术手段,但是热泵系统受环境温度、系统流程等影响较大。相变储能技术可有效地提升热泵系统能效,并解决低品位能量在时间、空间上的不匹配问题。结合相变储能技术与热泵系统,从热泵制冷、热泵供热及热泵除霜三方面对相关技术与研究进行了归纳总结,并着重对相变材料的性能进行了阐述。针对目前相变储能技术在热泵系统中的应用问题进行了探讨,发现提高材料储能密度、强化换热、结构优化等方面是未来的发展趋势,为进一步推广相变储能技术在热泵系统中的应用提供依据与支持。The"Double Carbon"goal requires reaching carbon peaking by 2030.Heating and cooling energy consumption accounts for a large proportion of carbon emissions.Heat pump technology is an effective technical means to achieve energy saving and emission reduction,but heat pump systems are greatly affected by environmental temperature and system processes.Phase change energy storage technology can effectively improve the energy efficiency of heat pump systems and solve the problem of mismatch between low-grade energy in time and space.Combined with phase change energy storage technology and heat pump system,the relevant technologies and research are summarized from three aspects:heat pump refrigeration,heat pump heating,and heat pump defrosting,and the performance of phase change materials is emphasized.The current application problems of phase change energy storage technology in heat pump systems are discussed,and it is found that improving material energy storage density,strengthening heat exchange,and optimizing structure are the future development trends,providing basis and support for further promoting the application of phase change energy storage technology in heat pump systems.
