Variable Volume Chilled Water Pumping System Controls
daytonashrae.orgchilled water coils and bypass loop with 2-way valve • The single primary pump pumps water through the chiller and to the coils. • Water Differential Pressure Transmitter near the end of the piping run varies the speed of the VFD. The flow meter is used to modulate the bypass valve to maintain minimum chiller flow requirement.

www.trane.comHandbook suggests that chilled-water coils are best selected with water velocity between 2 to 4 ft/sec, at design conditions.5 This recommended range is intended to provide a good balance between coil size and minimizing both air and water pressure drops. But water velocity is also important because it is one of the key factors for
