Abstract
A detection system and method of detection directed towards the detection of refrigerant leaking from a refrigerant circuit in a heating, ventilation, air condition, and refrigeration (HVACR) system. The system including a refrigerant circuit utilizes a mixture of working fluid and an additive. The system also includes a detection device that can detect the additive when external to the refrigerant circuit. A method of detecting leaking refrigerant includes adding a detectable fluid to a refrigerant circuit.
