摘要(Abstract)：

在现有汽车空调系统零部件的基础上,搭建了湿压缩-吸收式二氧化碳(CO2)循环汽车空调样机;并与采用同样零部件的R134a系统进行了对比性试验。实验结果显示:在相同的工况下,湿压缩-吸收式CO2系统的压力不超过3.5MPa,制冷量达到R134a系统的80%,COP达到了60%。显示了湿压缩-吸收式CO2汽车空调系统具有的潜在竞争力,为CO2汽车空调研发提供了新的思路。
An automotive air conditioner prototype is established for wet compression-absorption carbon dioxide cycle based on commercially available R134a components.The performances are tested and compared with the R134a System.Results shown that the pressure of reduce pressure CO_2 system is no more than 35bar,and the capacity is about 80% of R134a,and the COP is about 60% of R134a.The experiments demonstrate a competitive potential of reduced pressure CO_2 system and an opportunity of CO_2 refrigeration application.
