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 conditions. The system includes a heater (increases the air temperature in all operating modes of the system), an air conditioner (reduces air temperature and humidity), an air blower (fan) and air ducts with a filter (provide air exchange in the cabin, clean the air from dust), as well as a control unit (controls all elements of the system to obtain the specified comfort parameters)
