Abstract

See full text

In one embodiment, a water system includes a compressor, a condenser fluidly coupled to the compressor by refrigerant tubing, a modulating motor-controlled valve configured to alter a flow of water through the condenser, an accelerometer mechanically coupled to the water system, and a water system controller. The water system controller may be configured to perform an automated anti-water hammer procedure. During the automated anti-water hammer procedure, the water system controller may be configured to activate an operating procedure for the water system, transmit a control signal to the modulating motor-controlled valve, receive vibrational measurements received from the accelerometer, compare the vibrational measurements measured by the accelerometer to a predetermined vibration level associated with the operating procedure, and adjust the opening position and opening speed of the modulating motor-controlled valve for the operating procedure if the vibrational measurements exceed the predetermined vibration level associated with the operating procedure.
