Heating and ventilation system — general information (Peugeot Partner I)

The heating and ventilation system includes a four-speed electric blower (located behind the front panel), ventilation deflectors for air flow to the face in the center and at the edges of the dashboard and air ducts in the front footwells.

The control unit is located on the front panel. The controls operate dampers that direct and mix air through various parts of the heating/ventilation system. The dampers are located in the air distribution housing, which acts as a central distribution device, passing air to the various air ducts and vents.

Cold air enters the system through a grille at the rear of the engine compartment. If required, the air flow can be increased using a blower fan. The air then passes through various channels according to the control settings. the "used" air is removed through ducts in the rear of the vehicle. If warm air is required, cold air is forced through the heater core, which is heated by the engine coolant.

On models with air conditioning, the supply of outside air into the vehicle can be suspended if necessary, allowing air to circulate inside the vehicle. This is useful for preventing unpleasant odors from coming from outside the car, but can only be used for a short time, as the air recirculated inside the car soon becomes stale.
