内に制御される。The temperature Tk in the thawing chamber (5) is set to the set value Tm (for example, 10°
If the control width is lower than the lower limit (8°C) of C), the electromagnetic damper (16) closes to stop cooling, and the electromagnetic valve (20) opens, discharging heat from the high temperature part (17a) of the compressor (17). The amount of heat is transferred to the heat sink (19) via the pipe (18), and the heat sink is heated and the temperature Tk rises. Then, Tk
When the upper limit of the control width of IJ<T m is reached (for example, 12° C.), the electromagnetic damper (16) is opened and the electromagnetic valve (20) is closed, and cooling is performed by the inflow of cold air. In addition, when Tk reaches the lower limit of the control width of Tm (e.g. 8°C), an electromagnetic damper (
16) is closed, and the solenoid valve (20) is opened, and the amount of heat is transferred from the high temperature part (17a) of the compressor (17) to the heat sink (19) via the heat pipe (18), and is heated. Therefore, the temperature Tk in the thawing chamber (5) is controlled within a control range around the set value Tm by opening and closing the electromagnetic damper (16) and the electromagnetic valve (20).

Is the thing to be unzipped rsoog? ” becomes rYEsJ, the set values of the timer (42) become t and s corresponding to 500g, and the timer (42) operates. When this timer (42) is activated, the outside air temperature T is set at the outside air temperature set value Ts (for example, 1
5℃) or lower, the compressor (
17) changes from normal freezer control to operation rate control. That is, when T≦Ts, the operating rate of the compressor (17) is controlled linearly based on the comparison output between the detection signal of the refrigeration room temperature sensor (28) and the corresponding set value, as indicated by the dotted line UQ in FIG. The freezer control is canceled and the compressor (
17) is operation rate control controlled at a preset operation rate U o (for example, on time = 36 minutes, off time = 12 minutes), as shown by the solid line Us in FIG.
