<p>A system for automatic control of the temperature of air introduced into the passenger compartment (8) of a vehicle with a heat engine has an auxiliary radiator (1) connected to a cooling water circuit (2,3) of the engine, and a fan (4) for making the air which is conveyed into the passenger compartment (8) pass through this radiator (1). The system includes a cock (11) controlled by an electric motor for regulating the quantity of water which passes through the radiator (1), and an electronic circuit (12) for detecting the air temperature in the compartment (8) with respect to a predetermined set value and consequently controlling the electric motor which opens and closes the cock (11). Sensor (16) is responsive to the temperature of ambient air in the vehicle, which a sensor (13) responds to the temperature of air in the duct (6). The sensor signals are proportionally combined. <IMAGE></p> |
