APPARATUS FOR DETECTING LEAKAGE IN A COOLING SYSTEM AND METHOD OF DETECTING LEAKAGE

摘要

The present invention relates to leakage detection apparatus (1) for detecting leakage in a cooling systenn (2) or in a sub-unit of the cooling systenn (2), in particular a refrigerator. The leakage detection apparatus (1) includes an inlet (3) for receiving a pressurized fluid from a supply apparatus (4), an outlet (5) for pressurizing the cooling system (2) or the sub-unit of the cooling system (2) with the fluid received by the inlet (3), a valve (6) fluidly connecting the inlet (3) and the outlet (5) and a pressure sensor (7) for detecting a fluid pressure in the outlet (5). The leakage detection apparatus (1) according to the present invention further comprises a first temperature sensor (9) for detecting a fluid temperature in the outlet (5), a retrievable memory (8) for recording the detected fluid pressure and fluid temperature and a control unit (10) adapted to pressurize the cooling system (2) or the sub-unit of the cooling system (2) to subsequently close the valve (6) and after a settling time, to periodically record a simultaneously detected fluid pressure and fluid temperature into the memory (8).
