Abstract (en)
[origin: WO2014191035A1] 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 con¬ figured for detecting a leak in the refrigeration circuit (1a) based on the refrigerant temperature measured by the subcooling temperature sensor (6). The con¬ denser (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 the expansion device (8) of the at least one evaporator (10) through a receiver-free connection line (7).
