PROBLEM TO BE SOLVED: To ventilate the inside of a box-shaped unit and to prevent dew condensation without making air stagnate by providing a fan and ventilating holes inside the box-shaped unit. SOLUTION: A fan 12 is provided inside a box-shaped unit 11 and two pieces of ventilating holes 14, 15 are provided in the front wall 13 of the unit 11. In this structure, when a fan 12 is driven, air is inhaled from the ventilating hole 14 as shown by an arrow (m) and exhausted from the other one 15 as shown by an arrow (n) so that the inside of the unit 11 is ventilated and room temperature is maintained. If the inside of the unit 11 is cooled below the temperature of the outside air, the inside temperature never drops below the dew point, resulting in no dew condensation. Even if it is cooled below the dew point, the condensation inside the unit 11 is preventable, because it is ventilated. |
