Technical information Air-Conditioning Air conditioner operation

Operation of the air conditioner

The main components of automotive air conditioners are the same as other air conditioners. They include a compressor, condenser, refrigerant management and the evaporator. The difference in system operation and maintenance. The latest EPA regulations require certification for individuals, repair or maintenance of automotive air condirioners. They should be able to correctly use of approved equipment.

In a typical vehicle air-conditioning systems, belt-driven compressor is mounted on the engine. The condenser is installed ahead of the car radiator. This allows cold air through the condenser. Evaporator installed in the Plenum chamber in the passenger compartment. All these devices are connected between the wires and hoses.

Liquid flows refrigerant from the condenser to the liquid receiver. EC refrigerant dried and filtered. Then it flows through the control device and the tor. In the evaporator, the refrigerant evaporates and absorbs heat. The vaporized refrigerant, finally, flows back through the suction line of the compressor.

Low vapor pressure of the refrigerant enters the compressor on the low side.

Steam enters the cylinder and the piston is compressed. She is discharged through the high side back to the condenser. The heat of compression and the latent heat of vaporization is absorbed by the refrigerant transmitted air passing through the condenser fins. At this point, the process is repeated. Meanwhile, fan (fan forces air through the evaporator. In the result of the cold air is routed to the interior of the car through the air distribution ducts and grille...
