Air distributor for ventilation system (Renault Symbol 2)

The heating system uses the heat generated by the engine. The heater radiator included in the engine cooling system accumulates heat, and the air flow washing the radiator fins delivers heat to the car passengers. The control handles set different directions for the air flow, regulate the intensity of its heating and the volume of air supplied.

If necessary, the flow of hot liquid entering the heater radiator is blocked and the system distributes cold air. The air conditioner allows you to constantly maintain the set temperature in the cabin.
