Chw flow
WebCHW is pumped from a hot well tank to the chillers by three 20 HP recirc pumps; while nominally installed as one per chiller, the recirc pumps share a common header arrangement so any pump can flow to any chiller. The process CHW is pumped from the cold well tank to the plant by five 75 HP process pumps, and a separate 25 HP pump … WebFeb 28, 2012 · Say the CHW gpm flow was 4.2 and the HW gpm flow was 1.4 at 180/160. I selected the FCU heating with a fixed gpm of 4.2 (same as CHW), then reduced the HW temps, so they matched the load at the CHW flow of 4.2 gpm. This worked great for the FCU's, as I got to something like 95 EWT, which was excellent. But when I reviewed the …

(The pump law is similar to the fan law: When pump speed is reduced, energy consumption is cut by the cube of the reduction in speed.) However, any control scheme change needs to consider minimum chiller and cooling tower flow limits. 3.
