PROBLEM TO BE SOLVED: To enable a fast discovery of leakage of refrigerant from refrigerant circuits, and effect treatment to the leakage in a refrigerator having a system of at least two refrigerant circuits. SOLUTION: This refrigerator has at least two systems of refrigerant circuits C1, C2. There is provided further a sensor for use in sensing each of cooling temperatures of cooling devices 10A, 10B in each of the refrigerant circuits C1, C2, and there is also provided a control device to which an output from each of the sensors is inputted. This control device judges that a refrigerant leakage occurs in the refrigerant circuit having a high cooling temperature in the case that a difference in cooling temperatures of each of the refrigerant circuits C1, C2 reaches a specified value. |
