Large buildings with varying heating and cooling requirements need large plant equipment. This is typically located within chiller, HVAC or plant rooms. Failure or faults of this equipment can cause significant loss of refrigerant charge, which may go unnoticed. Small leaks can make the whole system inefficient and more expensive to operate but also pose a health risk to occupants as refrigerant gas depletes oxygen and can in some cases cause suffocation.
Plant / HVAC / Generator Rooms
Installing a fixed point refrigerant gas leak detection system will monitor for potential leaks continuously and can give audible/visual alarm as well as the ability to connect to a BMS if available.
Sensors are positioned close to primary sources of potential leaks e.g. near fan coil units, pipework joints, compressor compartments of chillers or the base of pipework risers.
Sensors can be stand-alone or multiple sensors can be linked to master panels for central monitoring.
