Reason for Pressure drop between the discharge of chiller and Suction
Reason for Pressure drop between the discharge of chiller and Suction
(OP)
We have Chilled water system with Three Chillers catered by Four Primary Pumps and four Secondary pumps primary pump flow is 155 Meter cube per hour, where as secondary pump is 117 M3 per hour.
The suction at Secondary pump is negative Inlet pressure to Chiller from primary pump is 1.8 Kg/cm2 outlet is 1 Kg/cm2 and suction of secondary pumps are minus 0.8 Kg per cm2.
Both the pumps are grundfos why there is pressure drop of 1.8 Kg/cm2 {1-(-0.8)}
