闭式水系统中补水泵的设置
Setup of makeup water pumps for closed water systems
摘要：
结合相关规范的规定，提出了暖通空调闭式水系统正常补水泵和事故补水泵应分开设置。正常补水泵用于水系统正常运行时的补水，流量宜为系统水容量的1％或者供热系统循环流量的2％，并进行变频调速控制；事故补水泵台数不宜过多也不宜少于2台；事故补水泵和正常补水泵均可不设备用泵。
Abstract：
With the provisions in relating codes, states that normal makeup water pumps and accident makeup water pumps should be set separately for a closed HVAC water system. Normal makeup water pumps provide makeup water in normal operation with the water flow rate of one percent of system water volume or of two percent of circulating water quantity of a heating system, applying variable frequency control at the same time. There should not be too many accident makeup water pumps in a system, but the number of the pump should not be less than two. It is unnecessary to install spare pumps for normal and accident makeup water pumps.
