Heating and ventilating, and/or air conditioning, apparatus for the cabin of a motor vehicle, especially an electric vehicle

Heating and ventilating apparatus for the cabin of a motor vehicle which defines a longitudinal axis of the vehicle, the apparatus having a plurality of elements disposed one behind the other in a substantially horizontal direction along the longitudinal axis, wherein the elements comprise:

• an air blower having an outlet for delivering unheated air through said blower outlet;
• a first duct connected to the blower outlet and defining an unheated air transmission branch and an air heating branch adjacent to the unheated air transmission branch;
• a heat recuperator in the air heating branch;
• a selection flap valve between the blower and said first duct, for controlling the distribution of the unheated air from the blower between the two branches of the first duct;
• a second duct connected to said two branches for receiving air therefrom;
• at least one electrical radiant heater in the second duct;
• a distributor including a distribution valve for selectively distributing air received from the second duct;
• a plurality of ventilation ports for selectively receiving air from the distributor, said ports opening into different regions of the cabin of the vehicle;
• and duct means connecting each said ventilation port to the distributor.
