air conditioning Compressors

A vehicles  air conditioning compressor has an intake side and a discharge side.

The suction side draws in the refrigerant gas from the outlet in the evaporator;

sometimes this is done via an accumulator. Once the refrigerant is draw in it is

compressed and sent through the compressor where is can begin to transfer

the heat that has been absorbed from the inside of the vehicle. The discharge

side of the compressor releases the super heated refrigerant and send on its

way to the condenser.



Compressor Designs

Axial Compressor can have 5, 6, 7 or 10 cylinders that are parallel to the crankshaft. This type of compressor uses a double ended piston with opposing cylinders, driven back and forth by the swash plate. This is rotated b the compressor shaft.                                            

Inline Compressor has side by side cylinders. Pistons are connected to crankshaft via connecting rods, similar to an engine. The pistons, rods and crankshaft are lubricated by oil splashing from the crankshaft case which holds litres of refrigerant oil. The suctions and discharge reed valves are secured to a plate between cylinders and compressor head.                                                                                                                                                                                                                                                                                         

The V-Type compressor was designed and is used by the Chrysler Corporation. The compressor unit has two cylinders set at 60 º parts, creating a V look. The pistons are connected to the crankshaft via connecting rods. This type of compressor uses steel rings to steel pistons to cylinder walls and has a slump that holds litres of refrigerant oil.                                                                                                                                                       

A Radial Compressor uses four cylinders, the pistons bores are positioned at 90º angle apart around the compressors crankshaft. An eccentric lobe on crankshaft moves the pistons up and down and back and forth.                                                                

The Rotary Vane Compressor uses a shaft mounted motor rotating inside on an elliptical chamber. The rotating vanes draw in and compress and discharge the refrigerant. The rotor contains four slots 90º apart, each containing moveable vanes and blades.  Impeller rotates inside the chamber, the vanes are forced in and out maintaining contact with the chamber walls.                                                                                                                                                   

The Scroll Compressor incorporates two matching scroll pieces. One scroll piece is stationary and the other oscillated back and forth via an eccentric on the compressors crankshaft. The Scroll Compressor has fewer moving parts therefore it is a cooler (less friction) to run than other piston type compressors.
