2022年9月13日 · To calculate the head required for a chilled water pump, you need to know the following: • The total dynamic head (TDH) of the system – this is the sum of the static head, friction loss, and velocity head in the piping system • The flow rate of chilled water through the system.
In summary, the pump head for chilled water is in the range of 26-35m water column, usually around 32-36m water column. Note: Pump head calculation depends on specific refrigeration system conditions; avoid blindly applying empirical values.
