摘　　要：为了对CO_2气体冷却器进行系统全面的性能分析,根据CO_2制冷剂在亚临界区和超临界区的换热特性,以第二制冷剂量热器法和水冷气体冷却法为理论基础,结合企业实际测试需求研制了能够全面测试CO_2气体冷却器性能的实验台。其可测试的换热量范围是1.6~32.0 k W,测量精度高。实际选用了一个气体冷却器做验证,结果显示2种测量方法的偏差小于4%,满足企业验收标准。此实验台的设计可为相关性能测试实验台的研究提供借鉴。In order to conduct systematic and comprehensive performance analysis of CO2 gas cooler, according to the heat exchange characteristic of carbon dioxide refrigerant in subcritical and supercritical regions, based on the theories of second refrigerant calorimeter method and water-cooled gas cooling method, combined with the actual demands of enterprise, carbon dioxide gas cooler test laboratory which could do performance analysis comprehensively was designed. Itg measuring rang was 1.6 -32.0 kW, and had higher testing accuracy. By testing a gas cooler, the results show that the deviation of two methods is less than 4%, meeting enterprise requirement. The testing laboratory also provides a reference for the development of relevant testing laboratories.
