The air supplied by the ventilation system to the car interior can be heated or cooled depending on the comfort conditions selected by the driver and passengers. The heating and air conditioning systems are separate, but the units and components of these systems are located in the passenger compartment in a common housing under the instrument panel. The entire flow of air supplied to the interior is directed for heating or cooling through the same casing. The temperature and speed of the air flow are regulated using the same controls.
The heat generated by the engine is transferred by the coolant to the heater radiator located in the passenger compartment. The air flow supplied by the ventilation system passes through the radiator and is heated by the heat of the engine coolant flowing inside the radiator.
