摘　　要：R134a的充注量直接影响热泵空调的系统能效系数(COP)等性能,减少其排放值一直是环保的重要目标。本文研制了电动汽车的二级压缩喷射热泵空调,并对其制冷剂充注量做了深入的试验研究。结果表明,随着环境温度的降低,制冷剂充注量也逐渐增加,为电动汽车空调系统的研究提供参考。The refrigerant charge amount of R134a directly affects the performance of coefficient of performance(COP)of heat pump air conditioning.Reducing its emission value has an important issue of environmentalprotection.In this paper,a physical objects of two-stage compression injection heat pump air conditioning systemfor electric vehicles was developed,and the experimental study on the refrigerant filling quantity is done.The testresults show that with the decrease of the ambient temperature,the refrigerant charge gradually increases,whichprovide reference for the study of air conditioning system for electric vehicles.
