WebNov 25, 2009 · The return connection to the primary main is within 2 feet of the discharge connection. The close connection is in case the AHU flow is higher than the chiller flow (possible). The excess flow causes the water in the chiller main to flow "backwards" within the 2 feet between the branch main connections without disrupting overall flow- say 120 ... Lack of chilled-water flow in closed-loop chiller systems remains a common complaint among users. The problem usually traces back to improper system piping. Fig 1: If piped correctly, closed-loop chiller systems provide adequate chiller water flow at the optimum curve of the circulating pump without problems.

WebApr 1, 2024 · The calculations of the pipe diameter need to be correct so that the velocity of the system is optimized and efficient. If velocity is minimized throughout the system, then the water will be able to freely run and cool proper areas. Additionally, there will be less corrosion if the velocity is kept to a minimum.
