Expansion Tank (CHW)-FINAL - Engineering Pro Guides

tank has a pressure of 14.7 psia.As the chilled water pressure increases above 14.7 psia,the chilled water will flow into the expansion tank.On the other hand,say the bladder/diaphragm is pressurized to 25 psig,then chilled water will only enter the tank when the chilled water exceeds 25 psig.Delaying the chiller from cycling off would likely work better using supply side control.
