Claims

[Claims for Utility Model Registration] (1) A refrigerator in which brine 14 in a cooling brine tank 8 is cooled as a heat medium by a refrigeration circuit, and the brine is circulated to a heat exchanger 10 in the refrigerator by a pump 9. A hot brine tank 24 with a built-in heater 25 provided in parallel with the heat exchanger, and a first electromagnetic tank 24 provided in parallel with the heat exchanger and in series with the hot brine tank and opened during defrost operation. a second electromagnetic valve 23 that is provided in a piping path between the cooling brine tank, the heat exchanger and the hot brine tank, and is opened during cooling operation;
A refrigerator comprising: (b) a defrost end temperature detection device 27 provided on the outlet side of the heat exchanger to detect the end temperature of the defrost operation. (2) The refrigerator according to claim 1, wherein the pump 9 is attached to the outlet side of the heat exchanger. (3) Scope of Utility Model Registration Claims Paragraph 1 or 2, which provides a timer that generates a switching signal after a predetermined time has elapsed, and defrost operation is automatically and periodically performed by the switching signal from the timer. Refrigerator as described in section.
