Chilled water system balancing.

Author(s) : PENNY D. S.

Type of article: Article

Summary

The paper describes a method for simple balancing of a chilled water circuit having a number of grouped parallel branches. Taking one branch, the balancing valve on the branch furthest from the mains becomes the reference valve. This is set at a pressure drop to give the required branch flow rate. A further valve, called a partner valve is fitted downstream from all balancing valves in parallel branches. On the adjustment of the balancing valve at the outlet of each branch, the circuit flow is compensated by adjustment of the partner valve to keep constant pressure drop across the reference valve. If further circuits are connected to the same mains, the return main must also have a partner valve to balance each circuit. The operational sequence is described in easy steps. D.W.H.
