Air conditioning installation

Abstract

The invention relates to a conditioning installation (heating or cooling) for the air of an enclosure such as the passenger space of a motor vehicle. The installation comprises a first control means for providing the heating and/or cooling capacity of a heating and/or cooling apparatus at a preset value which is adjustable between first and second limits, and an extra control means for imparting to the capacity of the apparatus the first or second limit value without modifying the preset value when active and for imparting to the capacity the preset value when disconnected. The first control means comprises a sealing shutter capable of pivoting continuously about an axis spaced apart from the radiator between two limit positions. The extra control means comprise a sealing member capable of being placed in a first position sealing off the space separating the free face of the radiator and the shutter axis of the first control means, and in a second position in which it seals off the portion of the duct which is not sealed off by the radiator.
