摘 要 ：介绍了国家标准已有的测试方法，分析其优缺点。阐述了二次节流的原理，设计了一种基于二级节流的节能型压缩冷凝机组测试方法。介绍了测试装置的组成、调节过程和内部热量平衡机理。测试方法采用水作为载冷剂，较好的利用了系统内部的冷热源，减少了设备投资、测试时间和运行费用。 关键词： 节能； 压缩冷凝机组； 二次节流； 测试装置 An Energy-Saving Testing Device Of Compressor Condensing Units Jiang Yunfeng Du Kai Abstract: Exiting testing methods are introduced. Their advantages and disadvantages are analyzed. The theory of secondary treatment is introduced .Based on this theory, one kind of energy-saving testing device of compressor condensing units is designed. Components of the device and regulation process are described. Internal heat balancing mechanism is discussed. Water can be used as secondary refrigerant. Cold and heat source in the system will be used fairly well. Initial investment and operation cost will be reduced. The testing time will be also decreased. Keywords: energy-saving; compressor condensing units; secondary treatment; testing device 参考文献 [1] GB/T 21363-2008 《容积式制冷压缩冷凝机组》[S]. [2] 沈希 《制冷压缩机制冷量测试系统的若干理论问题与实践》[D] .浙江：浙江大学博士学位论文， 2006.
