Features of the heating system (Chevrolet Aveo T300)

The heating, air conditioning and ventilation system is a single complex that provides the most comfortable conditions in the car regardless of weather conditions and driving mode. The system includes a heater (increases the air temperature in any operating mode of the system), air conditioner (reduces air temperature and humidity), air blower (fan) and air ducts with a filter (provide air exchange in the cabin, clean the air from dust), and also the control unit (controls all elements of the system to achieve the specified comfort parameters).

The car is equipped with a liquid-type cabin heater.



The heater radiator is connected to the engine cooling system by two hoses running in the engine compartment. The radiator is placed in a plastic casing of the climate control unit, installed under the central part of the instrument panel.



Main components of the heater (figure 12.1):

• heat exchanger (radiator) 6 of the heater, designed to heat the air entering the passenger compartment with the heat of the engine cooling liquid;
• fan (air blower) 11. Electric motor 12 of the fan with excitation from permanent magnets, providing adjustable supply of outside air to the heater and air conditioner flaps. To obtain different values of the fan speed, a block of additional resistors is installed in the power supply circuit of the electric motor;
• flap 15 of the air temperature regulator coming from the heater into the passenger compartment. The amount of air passing through the heater heat exchanger and outside air passing bypassing the heat exchanger depends on the change in its position;
• 2 flaps distribute air coming from the heater through air ducts into the passenger compartment or for blowing the windshield.
