Abstract:
An installation for heating and/or ventilating a passenger compartment of a vehicle, the passenger compartment defining an internal space and an external space, the installation comprisingmeans for producing flows of chilled air and warm air, at least one air distribution channel connected to said means for producing flows, at least one air diffusion inlet connected to said at least one air distribution channel and providing air flow to the internal space, wherein said means for producing flows is operative to increase pressure in the internal space, a vehicle seat, a vehicle windscreen having a top and a bottom, a plurality of air extraction channels in flow communication with the external space, a plurality of extraction vents in communication with the internal space, each extraction vent connected to at least one of said plurality of air extraction channels whereby the internal space is placed in flow communication with the external space, said extraction vents operative to remove air from the passenger compartment as a result of a pressure difference between the internal space and the external space, each of said plurality of extraction vents located in the passenger compartment and defining a passenger comfort zone, wherein at least one of said plurality of extraction vents is integrated into the vehicle seat and at least one of said plurality of extraction vents is proximate the top of the windscreen, and apportioning means for selectively controlling distribution of extracted airflow between different extraction vents and for increasing distribution and circulation of air in at least one of the passenger comfort zones.
