Naval Air Station in MD – Chiller Replacement

GMS was responsible for the mechanical, electrical and controls on this project to install a new air cooled scroll chiller.  The chiller was mounted on a concrete slab and hooked up to the existing glycol tank and chilled water supply & return piping. In addition GMS installed isolation valves, thermometers and insulation on all outdoor chilled water piping. The new chiller was integrated into the existing BACNET DDC control system but all interface control points from the new chiller control to existing BACNET DDC needed new wiring. A new immersion temperature sensor was installed on chilled water supply to the building and hooked up to the DDC control system.
