The upper end portion and the lower end portion of each tube member 15a of the cold radiation panel 15 are connected to each other, and the fluid flows into each tube member 15a via the cold / hot water pipe 15b. The fluid in the pipe member 15a and the cold / hot water pipe 15b is cooled by the above-described heat pump and circulated by a circulation pump (not shown). At the time of this circulation, the fluid passes through the latent heat unit 50, so that heat exchange between the granular latent heat storage material and the fluid is performed. The cooled fluid flows through the pipe members 15a of the cold radiation panel 15 from the upper end toward the lower end, and is radiated from the cold radiation panel 15 (cold heat is radiated), whereby the inside of the cold and dark place 12 is cooled. Further, a heat loss from the latent heat unit 50 is also used for room cooling.
A temperature sensor (not shown) is installed in the cool and dark place 12, and the heat pump and the circulation pump are controlled by this temperature sensor so that the temperature of the cool and dark place 12 is 20 ° C. or less (about 15 ° C.). Has been.
As a cooling means, an air conditioner is generally used, but it is preferable in the present invention because there is no product that can cool the room to about 15 ° C., and dehumidification proceeds with cooling to promote food drying. Absent. On the other hand, in the case of cooling by a radiation panel, drying is suppressed, which is preferable for food preservation.
