Abstract
The root cause of refrigerant leaking from a household refrigerator’s compressor system can be traced to micro- and macro-damage within the sealed system. To determine and prevent further leakage, it is necessary to equip the refrigerator with an alarm device featuring a thermal balloon on the exterior of the freezer evaporator. This innovative device is designed to react solely to any drop in temperature across the surface of the freezer evaporator below its nominal value. For this purpose, the thermal energy indicators of a household refrigerator, considering variable ambient temperatures and the required refueling dose of the compressor system, were determined. This device does not replace an existing one; rather, it serves as a complement by interrupting the electrical circuit to the start-up relay; thereby, disconnecting the compressor from the power supply and alerting users to a potential refrigerant leak in the compressor system. This device can be implemented in compressor systems utilizing any type of refrigerant.
