Auto Air Conditioner Compressor

Auto Air Conditioner Compressor is divided into two types: stand-alone (single engine driven), non-independent (driven by the automobile engine.)

Non-independent air-conditioning is more common. After starting the car with the engine compressor clutch pulley with rotation. Air-conditioning turned on, the electromagnetic power clutch, belt drive with the sucker by the electromagnetic coil magnetic pull, the compressor along with rotation.
Set according to the temperature inside the thermostat control the compressor stop, start.

Compressor works:

Refrigeration system works as follows: When the compressor, the compressor suction out from the evaporator refrigerant temperature low pressure gas, the compressed refrigerant temperature and pressure increase, and was sent to the condenser. In the condenser, the high temperature and high pressure gaseous refrigerant to the condenser heat transfer to the vehicle through the air and liquid into the liquid. Liquid refrigerant flowing through throttle device, the temperature and pressure decreased, and the evaporator. In the evaporator, low temperature and pressure of the liquid refrigerant through the evaporator of the car absorbs the heat and evaporation of air into gas. Compressor suction gas was again the next round of circulation. Thus, by the refrigerant circulating within the system, constantly absorbing heat from air inside the car side by side into the air, so that the air temperature inside the vehicle declined.

From the cooling system works, we can see: the refrigerant circulating in the system continuously, each cycle includes four processes: compression, condensation, throttling process, the evaporation process.
There are several compressor, scroll, and rotary vane, oblique plate, piston and other principles are that matter to low temperature and pressure of the gas is compressed into high temperature and pressure of the gas.


The whole system without considering the pressure loss of only two cases is the high and low pressure.
Air conditioning compressor is in the air conditioning refrigerant circuit refrigerant from the compression driver role. Working circuit carved evaporation zone (low pressure area) and condenser (high pressure area). Indoor unit and outdoor unit is high or low pressure areas, respectively (see the work of the state may be), the compressor installed in the outdoor unit in general. Refrigerant compressor to extract from the area of ??low pressure to high pressure area after compression to the cooling condensation, heat emitted by the heat sink to the air, the refrigerant gas into a liquid from the pressure increased. Refrigerant then flows from the high pressure zone area of ??low pressure spray into the evaporator through the capillary, the sudden drop in pressure, liquid refrigerant into a gaseous state immediately, through the heat sink absorbs a lot of heat in the air.

In this way, the machine constantly work to keep one end of the area of ??low pressure refrigerant in the heat absorbed and then sent into the atmosphere high pressure area, played the role of temperature regulation.
