This Architectural Drawing is of INSTALLATION DETAILS OF GENERAL PUMP OF CHILLER SYSTEM. The Pump is used in chiller is, suction centrifugal pumps, Chilled water or chiller pumps are typically inline or end suction centrifugal pumps for moving water around the chiller system, used for primary, secondary, constant, variable or as a shunt pump. The job of primary pumps is to make sure that the chillers are having the required water flow rate while secondary pumps are regulating the amount of chilled water supply to air handling units based on the cooling demand. A chilled water system uses water instead of air to cool your home. The water absorbs heat from the home and disperses it outside. The system cools the water down to a temperature of 40 degrees and then circulates it through the water coil's air handler. For more details and information download the drawing file.
