Compressor Types and Technology
Piston Compressor
As the swash plate fixed on the shaft rotates, the piston reciprocates. This design features a complex structure, is light in weight, easy to install in small engines, and has a short stroke distance.
Rotary Compressor
Features short stroke distance and excellent balance, but can generate heat due to moisture. It lacks power at low speeds and consumes high horsepower at high speeds.
Scroll Compressor
Small in size and light in weight, capable of achieving high-speed rotation. The vortex rotates together with the gap in front of the vortex disk to generate pressure.
Mounting and Drive System
Mount & Drive Assembly
Consists of a bracket to mount the compressor to the engine, a belt idler pulley, compressor drive belt, and possibly an extra drive pulley for the crankshaft.
Compressor Mount
Manufactured from plate, cast iron, steel, or aluminum, this bracket should exhibit excellent noise absorption qualities, especially when used with piston type compressors.
Idler Pulley
A small pulley normally used in conjunction with a belt adjusting mechanism, also employed when a belt has a long distance between pulleys to absorb belt vibrations.
Drive Pulley
Some vehicles do not have an extra pulley to accommodate an A/C drive belt. In these cases, an extra pulley is bolted onto the existing crankshaft pulley.
Air Conditioning Compressor Operation
The air conditioning compressor is generally driven by the engine via a V-ribbed belt. It compresses or circulates the refrigerant throughout the system. Different types of air conditioning compressors are available, and it is crucial to match the compressor size with the system requirements.
To ensure proper lubrication, the compressor is filled with a specific oil that circulates through the air conditioning system along with the refrigerant.
Installation Instructions
Before installing the new AC compressor, it is essential to flush the refrigerant circuit to remove contaminants and foreign bodies. Depending on contamination levels, use refrigerants R134a or R1234yf, or a special flushing solution.
Note that air conditioning compressors, filter-driers (accumulators), and expansion or throttle valves cannot be flushed. Since system contamination is always assumed or cannot be ruled out when the compressor is defective, the system must be flushed when replacing these components.
Ensure no residues of the flushing solution remain in the system. If necessary, dry the refrigerant circuit using nitrogen.
