摘　　要：测试了某机房冷热水机组在未运行机组冷水进出口阀门关闭与开启2种不同运行状态下的COP和制冷量,结果表明,阀门关闭时的COP要高于阀门开启时。分析了冷水泵、冷却水泵和冷却塔运行中存在的问题,提出了改进措施。Tests the COP and cooling capacity of a chilled and hot water unit in a machine room under two different operating conditions of the closed and open inlet and outlet valves of chilled water. The results show that the COP at the condition of closed valve is higher than that at the open valve. Analyses the operating problems of chilled water pump, cooling water pump and cooling tower, and puts forward the improvement measures.
