湿压缩-吸收式CO_2与R134a汽车空调系统性能实验比较

Performance Comparison of Wet-compression Absorption Carbon Dioxide Cycle with R134a in Automotive Air-conditioning System

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 CO2 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 CO2 system and an opportunity of CO2 refrigeration application.
