HVAC CHILLED WATER DISTRIBUTION SCHEMES A chilled water system is a cooling system in which chilled water is circulated throughout the building or through cooling coils in an HVAC system in order to provide space cooling. The principal objectives of
Also, supplying chilled water at 43 F (6 C) to a system designed for 40 F (4.4 C) will cause required system flow to increase and ΔT to correspondingly decrease. 2 In short, flow in the reverse primary direction in a decoupler bridge is usually not good, and a
There are several flow and energy measurement opportunities within a chilled water system, and ONICON offers an array of technologies specifically suited for this challenging application. Some of the considerations that drive the technology selection include
