Air cooled chilled water system
Air cooled chilled water system
(OP)
Experts,
In a variable primary flow chilled water system (air cooled), total frictional loss is 6.5 bar as per calculation. Is this same as chilled water system working pressure, or different?
Thanks in advance

Imagine a pump at the bottom of tall building. You are pumping away from your expansion tank and your fill pressure is 40 psi. Your pump provides 30 psi to overcome friction losses (assuming a closed system) your pressure on the discharge of the pump would be 70 psi relative to ambient. On the suction side, 40 psi differential. As you move a way from the pump the pressure gets lower due to static (level rise) and flow losses...
