PURPOSE:To improve the cooling of an outer damper by passing cooling air between the interior and the exterior of an outside damper. CONSTITUTION:Cooling air which is inflowed via an inlet filter 18 is shielded by a vent partition plate 14 as designated by an arrow in the drawing, is introduced into a vent duct 16 from an inlet vent hole 15 by the pumping operation of the hole 15 and an outlet vent hole 17, and is exhausted from a vent duct 16 through the hole 17 and an exhaust duct 19. Since the cooling air can pass between interior and the exterior of an outer damper 2 in this manner, the cooling of the damper 2 can be improved, thereby preventing the heating due to wind loss. |
