PURPOSE: To obtain a dehumidifier at low cost by fitting an inner cylinder to the inside of an outer cylinder whose upper end communicates with a space formed inside a building body and which is fitted to the ceiling surface and installing a fan in the inner cylinder. CONSTITUTION: A building body 1 made of concrete is divided by a heat insulating panel 2 to form a low temperature warehouse 3 taking a prescribed space, and a dehumidifier 4 is fitted to the ceiling part thereof. In the dehumidifier 4, inside a heat transfer cylinder (outer cylinder) 5 whose lower end part is conical, a cylinder 6 is arranged coaxially to the cylinder 5 leaving a clearance between them in the lower part. In the upper part of the inner cylinder 6, a fan 7 is installed. In such a way, when the humidity in a space formed inside the building body 1 is high, air in the space formed inside the building body 1 is circulated between the outer cylinder 5 and the inner cylinder 6 and in the inner cylinder 6 to cool the communicating air by the outer cylinder 5 cooled by low temperature in the low temperature warehouse 3. Then, moisture in air is turned into dew to dehumidify air in the space formed inside the building body 1. |
