Abstract
An apparatus for heating and ventilating, and/or air conditioning, the cabin of a motor vehicle, and in particular an electric vehicle, comprises a series of elements arranged in a generally horizontal succession along the longitudinal axis of the vehicle. These elements comprise: a blower for producing a stream of cold air; a first duct fed by the blower and divided into a cold air transmission branch and an air heating branch which contains a heat recuperator; a selection flap valve for controlling the distribution of the air flow between the two branches; a second duct which receives the outlet air of both of the two branches of the first duct, and which contains at least one electric radiant heater; and a distributor fed by the second duct and including a distribution valve for distributing the cold or heated air between appropriate ventilating ports in the cabin.
