Furthermore, a drying duct (12) communicating with a blower port of a blower (9) through a drying damper (11) formed of a heat insulating material is provided, and the duct is provided in a pit (13) on the lower surface of the floor plate (7). The cooling duct (15) is provided to extend the (12) and communicate with the blower port of the blower (9) through the cooling damper (14), and the cooling duct (15) is provided near the well of the storage chamber (3). ) Is extended, and a differential pressure fan (17) is installed above the partition wall (16) between the storage chamber (3) and the machine room (4) so that the air in the storage chamber (3) is transferred to the machine room. The fan (17) is moved to (4), and ventilation fans (19) and (20) are attached to positions above and below the outer wall (18) of the machine room (4). Let air out of the machine room (4) by The outside air is taken into the machine room (4).

Further, as shown in FIG. 1, the dehumidifier (8) includes a cooling / dehumidifying evaporator (21), a room temperature restoring capacitor (22), a cooling scroll compressor (23), with adjustable output power. And an outside air intake duct (25) for taking in the atmosphere (humid air) from above through the dehumidification adjustment flaps (24). The room temperature dehumidified air from the capacitor (22) and the duct (25 ) Is mixed with the air from room temperature) to form normal temperature and constant humidity air, and the normal temperature and constant humidity air is sucked into the blower (9). The dry damper (11) is opened to remove the normal temperature and constant humidity from the blower (9). The air is sent to the drying duct (12), and the room temperature and humidity air is taken into the pit (13) from the blower port (28) of the duct (12) through the blower damper (27) which is opened and closed by the motor (26). Then, the room temperature and humidity are discharged through the partition plate (29) to the upper side through the opening (30) of the floor plate (7), and the room temperature and humidity are maintained inside the storage bottle (6) through the breathable bottom plate (31).
