Heating system
The main components of the interior heating system are an electric fan and a heat exchanger located in the box-shaped heater casing. The heat exchanger is connected to the engine cooling system via rubber hoses. The heater/air conditioner control unit is mounted in the vehicle's instrument panel. The coolant heated in the engine circulates through the heater heat exchanger, giving off its heat to the air filling the casing. When the interior heating is turned on, the plate damper opens, as a result of which the internal volume of the heater casing is connected to the volume of the interior. When the fan is turned on, the impeller of the latter begins to drive the air supplied to the interior through the heat exchanger, ensuring its intensive heating.
Air conditioning system
The system consists of a condenser installed in front of the radiator, an evaporator located next to the heater heat exchanger, a compressor mounted on the engine block, and a receiver-dryer equipped with a high-pressure reducing valve. All components are interconnected by refrigeration lines.
The fan drives the air entering the cabin through the evaporator heat exchanger, which operates in the opposite mode to the radiator. The refrigerant pumped through the heat exchanger evaporates, taking excess heat from the air. The temperature inside the cabin is reduced to the required comfortable value (at the operator's choice).
