This photo shows a new installation of a chilled water actuator and chilled water piping. The chilled water actuator is modulating and on a three way valve. The chilled water valve will modulate depending on the supply air temperature of the air handling unit which provides air conditioned air to the space. The wire seen is being used as a temporary chilled water pipe hanger so that final adjustments can be made to the piping before finalizing the chilled water piping installation. The chilled piping was installed with several unions so that if the chilled water actuator malfunctioned it could easilt be replaced.
The air handler being served by this chilled water actuator and chilled water piping serves a large commercial kitchen. In the summer it is critical for the air conditioning system to remove the heat produced by the ovens and grills so that workers remain safe and comfortable. The air conditioning increases the workers productivity and morale. The chilled water piping feeds chilled water to a chilled water coil inside the air handler. The blower in the air handler moves the air from the kitchen across the coil where the heat in the air is absorbed into the coil and the water. The conditioned air is then ducted back into the kitchen at a cooler temperature than when it left the kitchen through the return duct.
