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 working fluid that also contains an additive fluid. The system also includes a detection device that can detect the additional fluid external to the refrigerant circuit. A method of detecting leaking refrigerant is includes adding a detectable fluid to a refrigerant circuit.
