PROBLEM TO BE SOLVED: To prevent a part of diffused air from flowing into an air inlet on one side and avoid a drop in the efficiency of heat exchange by forming an air inlet on one side with a large number of opening faced behind and the eaves which cover the openings. SOLUTION: The air sucked up from an air inlet 3a is heat-exchanged with a heat exchanger 1 provided in a main body 1 and arraigned to blow off the heat-exchanged air from an air outlet 2a with a fan. An air inlet 3a provided on one side surface 3 of an outer shell comprises a large number of openings (b) provided with an outer shell made of a sheet metal and provided to face in the rear part of the side surface 3 and the eaves (a) formed expandingly outward by throttling the front of the openings (b). Since a part of the air blowing off from the air outlet 2a is sucked up from the air inlet 3a of one side surface 3 as a result, this construction makes it possible to prevent heat exchange efficiency in the main body 1 from being degraded. |
