闭式水系统中补水泵的设置

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。

Setup of make-up water pumps for closed water systems

With the provisions in relating codes,states that normal make-up water pumps and accident make-up water pumps should be set separately for a closed HVAC water system.Normal make-up water pumps provide make-up 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 make-up 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 make-up water pumps.
