摘　　要：压缩冷凝机组性能测试系统是针对压缩冷凝机组测试台运行过程中所需要的参数进行采集、监测以及处理的专门软件。根据GB/T 21363-2008和JB T9056《容积式制冷压缩冷凝机组》所规定的制冷压缩冷凝机组测试要求进行,采用Visual Basic面向对象编程语言为开发平台,利用VB加载的DLL文件来实现I/O端口的输入输出功能,通过MSComm控件实现串口通信功能,开发出了系统测量精度高、数据可靠、操作方便、功能齐全的测试软件。经过选取不同型号的压缩冷凝机组,将其接入该系统中进行测试,全面监测硬件软件的运行,分析测试数据并输出测试报告,验证了测试系统的准确性、可靠性。The performance test software for the condensing unit was developed according to the condensing unit performance test requirements of GB/T 21363 -2008 and JB T9056 （（ Positive displacement refrigerant compressor condensing unit））. It was special software for collecting, monitoring and handling the parameters in the process of testing the rated performance of the con- densing unit. The test software was developed based on the most commonly used programming language Visual Basic, used the DLL files to realize the I/O port input and output function and serial - port communication by MSComm control. We developed a high precision measurement system with reliable data, and simple operation, fully functional testing software. The different types of condensing units were selected to be constructed into the system for testing, monitoring the operation of the hardware and soft- ware, analysing the data and outputting the test report.
