AC compressor
DI Overview
The vehicle A/C the compressor is the heart of the vehicle A/C refrigeration system, It plays a role of
compression and conveying of refrigerant vapor.
EG
They work loops of the A/C the compressor include evaporation area (low pressure area) and condensation
area (high pressure area). The interior unit and the exterior unit of A/C system belong to high pressure or low
TR
pressure areas (depending on the work status) individually. The A/C the compressor is installed on the engine.
After the A/C is activated, it will be driven by the engine. A/C the compressor draws refrigerant from low
AX pressure area and compresses it, then send it to high pressure area for compensation. It released heat through
its fins into the air. At the same time, the refrigerant changes from gas into the liquid, and pressure increases.
The refrigerant flows from high pressure area to the low pressure area, and is injected into the evaporator
FR
through the capillary. The pressure decreases suddenly there and the refrigerant changes into gas. It absorbs a
great amount of heat through the fins from the air. The A/C the compressor keeps working in this way,
ST
continuously absorbing the heat from the low pressure area into the refrigerant and conveying it to the high
pressure area, and emitting to the air, so that play a role of air conditioning.
