A control valve in the line returning water to the building chilled water system will be used to maintain the setpoint. When the tempered chilled water supply temperature rises above 60°F the control valve shall modulate open. When the tempered chilled water

Control sequences for chilled water systems - Consulting

Jan 20, 2012 · As more air is moved across the cooling coil, a discharge controller begins to modulate the two-way chilled water valve open. As the chilled water valve begins to open, the chilled water differential pressure transmitter senses a drop in system pressure. This sends a signal to the chilled water control panel and VFDs.

CHILLER PLANT CONTROL

plant control system must also control the chilled water pumps (primary and secondary), condenser water pumps, cooling tower fans, and any other devices in the system, such as bypass valves and VFDs. Typical control of the primary chilled water pumps (see Figure 1) is as follows: the lead chilled water pump is start-
