This paper focuses on the performance of heat pump systems for electric vehicles.Taking a typical three-heat exchanger direct heat pump system as the object,the paper summarizes the boundary characteristics of the heat pump by studying the effects of key operating parameters such as heat exchanger ventilation,ambient temperature,internal circulation ratio and compressor speed on the heating performance of the heat pump system,and gives corresponding guiding suggestions on the optimization of the heating volume,COP value and heating demand for engineering applications.In addition,a multi-domain 1D passenger compartment model is optimized to evaluate the heating performance of heat pumps in winter,and a way to evaluate the thermal comfort based on the integrated PMV value is proposed.The potential space for energy reduction in the passenger compartment is revealed by investigating the influence of the matching characteristics of the air volume and the air temperature on the performance of heat pumps.
