Abstract
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.

Claim 1
Independent Claim
110 words
An air conditioning installation for an enclosure, such as the passenger space of a motor vehicle, comprising heating and/or cooling apparatus having a heating and/or cooling capacity; first control means, for said heating and/or cooling capacity of said apparatus, for providing said capacity at a preset value which is substantially continuously adjustable between first and second limit values; and extra control means, for said heating and/or cooling capacity of said apparatus, for imparting to said capacity said first or second limit value without modifying said preset value of said first control means when active, and for imparting to said capacity said preset value of said first control means when disconnected.
Claim 2
Dependent Claim
110 words
An air conditioning installation for an enclosure, such as the passenger space of a motor vehicle, comprising heating and/or cooling apparatus having a heating and/or cooling capacity; first control means, for said heating and/or cooling capacity of said apparatus, for providing said capacity at a preset value which is substantially continuously adjustable between first and second limit values; and extra control means, for said heating and/or cooling capacity of said apparatus, for imparting to said capacity said first or second limit value without modifying said preset value of said first control means when active, and for imparting to said capacity said preset value of said first control means when disconnected.
Claim 3
Dependent Claim
15 words
An air conditioning installation according to claim 1, wherein said apparatus comprises a heating radiator.
Claim 4
Dependent Claim
158 words
An air conditioning installation according to claim 1, further comprising a duct having walls, said apparatus has a free face and is coupled to walls of said duct to occupy a portion of the cross section of said duct and to present said free face opposite one wall of said duct; wherein said first control means comprises a sealing shutter pivotably mounted in said duct for substantially continuous movement about a first axis spaced from said apparatus and between two limit positions corresponding to said first and second limit value, respectively; and wherein said extra control means comprises a sealing member mounted in said duct for movement between a first position in which said sealing member seals off the space between said free face of said apparatus and said first axis of said first control means and a second position in which said sealing member seals off the remaining portion of said duct not sealed by said apparatus.
Claim 5
Dependent Claim
