More Information
Summary:A refrigeration circuit (1a) comprises in the direction of flow of a circulating refrigerant a compressor unit (2) for compressing the refrigerant, a condenser (4), and at least one evaporator (10) having an expansion device (6) connected upstream thereof. The refrigeration circuit (1a) further comprises a subcooling temperature sensor (6) located at an outlet of the condenser (4) for measuring the temperature of refrigerant leaving the condenser (4), a control unit (12) functionally connected to the subcooling temperature sensor (6) and configured for detecting a leak in the refrigeration circuit (1a) based on the refrigerant temperature measured by the subcooling temperature sensor (6). The condenser (4) comprises a liquefying portion (4a) configured for at least partially liquefying the refrigerant and a subsequent subcooling portion (4b) configured for subcooling and storing liquefied refrigerant, and the outlet of the condenser (4), particularly the outlet of the subcooling portion (4b), is connected to
