Its main job is to compress and transfer refrigerant gas through the car's A/C system.
How does a variable displacement compressor work?
A variable displacement compressor, also known as a reciprocating compressor, is designed to compress and transfer refrigerant gas using a piston/cylinder mechanism. The upward/downward motion of the piston creates varying degrees of pressure that work to suction refrigerant gas into the cylinder, compress it and expel the resulting cool air out into the car's interior. These pressure variations also work to open and close the intake valve, as well as open and close the exhaust valve.
How does an auto compressor work?
The high-pressure area has a suction that draws the refrigerant gas from the inside of the car and compresses it. Once compressed into a liquid form, it's sent to a condenser area where it works to convert the heat from the inside of the car into cool air. This cool air is then blown into the inside of the car through the low-pressure, output side of the compressor.
How does a short disk compress the refrigerant gas?
The tall disk remains stationary while the short disk compresses the refrigerant gas by rotating inside the tall disk. As the short disk rotates, it creates sealed off areas inside the tall disk, which contain varying degrees of pressure. As refrigerant is suctioned into the scroll, some of it gets trapped inside the sealed off areas.

What is the valve in an A/C system?
Along the A/C system, the condenser and evaporator are divided by the expansion valve, or the orifice tube in some vehicles. The valve/tube gauges the heat and pressure levels coming out of the condenser and accordingly regulates the refrigerant that enters the evaporator.
What is the name of the fluid that is used in air conditioning?
Traditionally referred to by the antiquated DuPont trademark Freon, refrigerant comes in three forms that have appeared in succession since the dawn of air conditioning: R-12, R-134A and HFO-1234yf. Much like oil and antifreeze, refrigerant is one of the fluids that facilitates a vital function in most vehicles.
What is an accumulator in a car?
On vehicles equipped with orifice tubes instead of thermal expansion valves, an accumulator is used in lieu of a dryer. As with a dryer, the accumulator filters dirt and eliminates moisture from incoming air before it passes through the A/C system.
What is a Quincy compressor?
