摘　　要：针对常规水冷式冷水机组测试系统无法进行使用侧为0℃以下低温制冷工况测试的问题,进行低温制冷工况测试的扩展设计,增加低温载冷剂循环系统和中间换热系统,并对扩展设计的低温制冷工况测试系统的试验数据进行分析。结果表明:该系统不仅可以实现低温制冷工况测试,而且工况稳定可靠,温度测试最大偏差在±0.3℃内,水流量测试最大偏差在±0.5%内。As the conventional water-cooled chiller test system can not carry out the test of low-temperature refrigeration conditions below 0℃ of use side,the extended design of low-temperature refrigeration condition test is conducted.The low-temperature secondary refrigerant circulation system and intermediate heat transfer system are added.The test data of low-temperature refrigeration condition test system after extended design are analyzed.The results show that this system can not only realize the low-temperature refrigeration condition test,but also achieve stable and reliable operating conditions with the maximum temperature variation of±0.3℃,and the maximum water flow variation of±0.5%.
