摘要

测试了新开发的应用R410A制冷剂的补气增焓热泵型电动汽车空调的制热性能,并与原应用R134a制冷剂的普通热泵机组的制热性能进行了比较。实验结果表明,新系统能可靠运行在-15℃及以上的低温制热区间,压缩机排气温度可以控制在56.3～83.0℃,机组制热量比R134a系统提升了17%,0℃以上的整体能效提升了21%。新系统解决了R134a系统低温工况下排气温度高、制热性能衰减严重的问题。
        Tests the heating performance of a new electric vehicle air conditioner with supplying air and increasing enthalpy for cooling and R410 A as refrigerant, and compares with the heating performance of ordinary heat pump unit using R134 a refrigerant. The experimental results show that the new system can run reliably in the low temperature heating range of-15 ℃ and above, the compressor discharge temperature can be controlled from 56.3 ℃to 83 ℃, the heating capacity of the unit is 17% higher than that of the R134 a system, and the overall energy efficiency above 0 ℃ increases by 21%. The new system solves the problem of high discharge temperature and severe attenuation of heating performance in the original system at low temperatures.
