System of heating and ventilation
|
1 – air distribution box,
2 – heater radiator,
3 – air supply case,
4 – fan |
Heater radiator
|
1 – case of system of ventilation,
2 – heater radiator,
3 – fastening screws,
4 – branch pipes |
Two types of system of heating are applied. On the main models the system of heating copes manually. On more expensive models the system of heating copes with the help of electronics. Both systems are identical, except for the control unit.
The control unit is located in the panel and for management uses valves of a folding shutter to distribute and mix the air given to salon through various parts of system.
Cold air arrives through a lattice in a back part of a motor compartment. Air from salon is removed via channels in a back part of the car. Heating of the arriving air is made by heated cooling liquid.
The switch of recirculation closes intake of fresh air while air in the car constantly circulates.
Prevention
For repair of system of heating and ventilation it is necessary to remove a steering wheel, an instrument guard together with a casing, forward walls of the intermediate console, facing of a subwindow partition, a combination of devices and a casing of a steering column.
