摘　　要：开发适用于CO_2跨临界及亚临界循环的蒸发器性能测试装置,该装置基于蒸气压缩循环,采用CO_2气体或液体流量计法作为主要测试方法。详细阐述系统原理和试验流程,并在此基础上进行2类蒸发器的性能测试。测试结果表明,该系统运行稳定且工况参数控制稳定性好,可广泛应用于CO_2直接膨胀式蒸发器的性能测试开发及CO_2管内沸腾传热特性的研究。On the basis of vapor compression cycle, one performance test device for CO2 evaporator is developed,which is designed to use for transcritical and subcritical cycle. The gas or liquid flow meter method for CO2 is applied in calculation of cooling capacity. The system principle and testing process are introduced in detail, and two types of evaporator are tested on this test stand. The results indicate that the test stand has the features of operating conditions stably and nice repeatability deviations. It could be widely used for the investigation of the performance test for CO2 direct expansion evaporator and the characteristics study on boiling heat transfer for CO2.
