6.1. Introduction


Fresh air for heating gets into car salon via the inlet device under a windscreen. Thus air flows round a heating radiator and through various zaslonka is distributed on separate nozzles. If heating is established on "heat" (warm), heating valves in a motor compartment for access to the heat exchanger open. The heat exchanger is in a heating radiator and heats up hot cooling liquid. Passing by hot panels of the heat exchanger, fresh air heats up and then arrives in car salon.

The temperature in salon of the car can be established depending on the provision of a rotary regulator in the left or right half of salon. The electronic monitor in the device of heating regulates time of opening of valves of heating depending on temperature in salon. Behind the heat exchanger and in the device of service there are internal sensors of temperature. Thus, the temperature in the car is supported approximately by a constant, irrespective of speed of movement of the car and external temperature.

For strengthening of capacity of heating the four-stage fan of heating serves. That having blown at separate steps occurred to various speed, switching on additional resistance is provided. Thanks to them the current, the fan arriving to the engine decreases, and having blown occurs more slowly. At the highest step of speed обдува additional resistance are disconnected.

If in system of heating there is an additional dust filter, catching of a dust, pollen, air pollutions and other microparticles is provided. Switching it is possible to close completely air access outside. Regulation of air occurs then via the special air filter in car salon.
