Pic. 1.6. Instrument panel and controls
Outside air can enter the passenger compartment through the door windows with the windows down and the air intake located in front of the windshield on the right and equipped with a dust filter that cleans the air entering the passenger compartment from dust, soot, plant pollen, etc. The air entering the passenger compartment through the air intake passes through the heater. Depending on the position of the control knobs of block 13 (see fig. 1.6) heating and ventilation control, either heated or cold air enters the car interior.
Pic. 1.8. Air distribution elements
The arrangement of bodies of distribution of streams of air is shown in fig. 1.8, the location of the heating and ventilation controls - in fig. 1.9.
The following air distribution organs are located in the vehicle interior.
1 - air ducts for supplying air to the legs of passengers in the rear seat.
2 - side nozzles for supplying air to the driver and passenger in the front seat or on the windows of the front doors. Direction of air flow is adjusted by turning the grille (in the vertical direction) and sashes (in the horizontal direction) by the handle 2, located in the middle of the grid. The flow intensity is regulated by moving the wheel 1 in the vertical direction. At the upper extreme position of the adjusting wheel, the air flow from the left nozzle is maximum, at the lower position, the air flow is blocked. The flow intensity control algorithm from the right nozzle is similar to the left one.
3 - nozzles for blowing windows of the front doors.
4 - nozzles for blowing the windshield.
5 - central nozzles for supplying air to the passenger compartment. The direction of air flow from the central nozzles is regulated in the same way as from the side nozzles (see point 2).
