【摘要】 分析了一开式冷冻水系统的回水管改造,将生产车间的回水从原来流回水池改为沿回水泵的管道流回冷冻站水池,这样就节省了P4、P9二台回水泵;同时,冷冻站的二台冷冻水泵进行变频改造,将扬程从40M降为20M,为了保持流量不变,用大功率的7#泵变频代替3#泵,用3#、8#泵变频后并联代替8#泵,节能效果十分明显,节省了大量的电费。
【英文摘要】 The articled has analyzed the return pipe reconstruction of the open chilled-water system.The return water of workshop is altered from the pool of workshop to the refrigeration station along the pipe of return pump.So the return pumps No.P4&P9 have been decreased by 2.And meanwhile,two chilled water pumps frequency conversion was modificated from 40M to 20M on head.Pump N0.3 was superseded by the variable frequency and higher power pump No.7 as same as flow rate.Pump No.8 was superseded by the variable freq... 附件下载
