摘　　要：利用KULI软件建立汽车空调系统仿真模型,分析了R1234yf汽车空调系统和R134a系统的压缩机排气温度、制冷量和COP等性能差异,在此基础上,对系统进行优化,将中间换热器引入R1234yf系统中,分析中间换热器带来的性能影响。结果表明:直接替代的R1234yf系统制冷量和COP分别最大降低6%和7%,增加中间换热器后的R1234yf系统性能提升约4%。KULI simulation models are built to analyze and compare the performance of R134a MAC system and the system with“drop-in”R1234yf replacement.The influence of an internal heat exchanger(IHX)on the R1234yf MAC system was also studied.The results show:the cooling capacity and COP of the“drop-in”R1234yf MAC system are lower than the R134a system by6%and7%,respectively;And with adding IHX,the performance of the R1234yf system with IHX increases by4%approximately.
