Interior ventilation and heating scheme
- 1 - liquid temperature indicator in the engine cooling system;
- 2 - rotary deflectors;
- 3 - hatch for air intake (on the engine hood;
- 4 – cover of the hatch of an air inlet;
- 5 - pipeline for draining the coolant;
- 6 - pipeline for supplying hot liquid to the heater radiator;
- 7 - heater valve;
- 8 - air distribution cover of the heater casing;
- 9 - control lever of the heater valve;
- 10 - control lever for the air intake hatch cover;
- 11 - three-position heater electric fan switch.
- Blue arrows - cold air;
- pink arrows - heated air;
- red arrows - coolant
The figure shows:
- the location of the controls for ventilation and heating of the cabin;
- movement of cold and heated air;
- coolant circulation.
The interior ventilation and heating are controlled according to the outside temperature.
Cabin ventilation
Outside air can enter the vehicle interior:
- with open swing windows of the front doors;
- with the windows of the doors down;
- through the deflectors 2, if you move the upper lever 10 to the right to control the air intake hatch cover;
- with the air distribution cover 8 open, if the upper lever 10 is moved to the right.
Turning the deflectors changes the direction of the air flow. If necessary, you can increase the amount of incoming air by turning on the electric fan with switch 11 to the appropriate mode.
Windshield fogging prevention
To protect the windshield from fogging, it is enough to send cold air to it, for which you need to move the upper lever 10 to the right, close the cover 8 and turn the deflectors so that the air stream is distributed over a large area of the windshield. To heat the incoming air, move lever 9 partially to the right, which controls the flow of coolant into the heater radiator.
Interior heating
For heating the car interior and protecting the windshield from freezing:
- move levers 9 and 10 to the right;
- turn on the heater electric fan;
- open the air outlet cover 8.
Warm air will be directed both to the driver's and passengers' feet and to the windshield. For faster heating of the windshield, close cover 8. If the ambient temperature is very low, move the lever 10 to the right by part of its stroke to limit the cold air inflow.
