CHWR stands for Chilled H2o Return. CHWR is commonly found in the chilled h2o system structure and schematic drawings. It's also typical to contain the CHWR term physically painted around the chilled water pipe to point the chilled drinking water circulation course from the air managing device towards the chiller.
BC means Branch Circuit. BC or BC controller is referring into the controller Utilized in the piping branch device in a very VRF system. It controls the quantity of refrigerant flowing to each circuit based upon the cooling demand.
It comprised of several modest-capability air conditioners that cools the server racks in lieu of your entire area. PACU is effective at exactly Management the temperature in the server racks.
ODT stands for Outdoor Thermostat. ODT is usually a thermostat Positioned outside the building utilised to control a secondary heating system when the outside temperature fall underneath the setpoint.
In the event the negative strain is critical, the exhaust system gained’t work anymore. As a result, MUA is necessary to make sure the space gained’t be become a vacuum Room and the exhaust system can constantly perform.
