Balancing a variable flow water system improves the control system.

Author(s) : PETITJEAN R.

Type of article: Article

Summary

The author discusses control possibilities in a chilled water circuit in which a number of air-cooling coils are fed in parallel through two-way control valves. Estimation of system pressure drop, coil cleanliness and availability of correct size of valve can affect operation causing problems such as overflow to the coil. The only reasonable way of correcting this is to fit a balancing valve. The author takes several examples to show design errors occurring if no balancing valve is fitted. Balancing valves are also diagnostic aids, giving the ability for easy measurement of water flows. D.W.H.
