The air conditioning system includes a condenser installed in front of the radiator, an evaporator located adjacent to the heater heat exchanger, a compressor mounted on the engine block, a dehydrator accumulator that includes a high pressure safety valve, as well as fittings connecting all of the above Components.
The heater blower blows warm air from inside the car through the evaporator heat exchanger (operating on the principle opposite to the operation of the radiator), where the transfer of heat from the air to the system refrigerant takes place. At the same time, the liquid refrigerant boils, turning into low-pressure vapor, and takes heat with it, leaving the evaporator.
Read the precautions at the beginning of the Section Removal and installation of the block of management of operating modes of a heater and air conditioner, concerning the potential hazard associated with the operation of the air conditioning system.
