Compressors :

1) Rotary Vane - Panasonic

Rotary vane compressors consist of a rotor with three or four vanes and a carefully shaped rotor housing. As the compressor shaft rotates, the vanes and housing form chambers.

The R134a is drawn through the suction port into these chambers, which become smaller as the rotor turns. The discharge port is located at the point where the gas is fully compressed.The vanes are sealed against the rotor housing by centrifugal force and lubricating oil. The oil sump and oil pump are located on the discharge side, so that the high pressure forces oil through the oil pump and then onto the base of the vanes keeping them sealed against the rotor housing.

During idle an occasional vane noise from the compressor may be heard. This is due to the time taken for lubricating oil to circulate through the A/C system.

2)Scroll type - Sanden

This compressor uses a unique design with two scrolls, one fixed and one is movable, both are inter-leaved.The movable spiral is able to ORBIT or oscillate without actually fully rotating. The movable scroll is connected to the input shaft via a concentric bearing.

As the movable spiral oscillates within the fixed spiral, a number of pockets are formed between the spiral. As these pockets decrease in size the refrigerant is squeezed, the pressure increases and is discharged through a reed valve at the discharge port in the rear section of the compressor.

3)Variable stroke - Harrison V5

The Delphi (Harrison) V5 compressor is a non-cycling variable displacement compressor.

The compressor varies displacement to control capacity to meet A/C system demand at all operating conditions. The compressor features a variable angle wobble plate in five (V5) cylinder axial piston design.

Displacement is controlled by a bellows actuated control valve located in the rear cylinder head. This control valve senses and responds to the system suction pressure or A/C system demand.

Through regulation of compressor crankcase pressure, the wobble plate angle, and therefore compressor displacement is variable.

In general, the compressor discharge pressure is much greater than the compressor crankcase. Which is greater than or equal to the compressor suction pressure.

At maximum displacement, compressor crankcase pressure is equal to the compressor suction pressure.

At reduced or minimum displacement, the compressor crankcase pressure is greater than the suction pressure.

The role of compressor

The compressor is an essential component of the air conditioning system in a vehicle. Its primary function is to circulate and compress the refrigerant gas, which is responsible for cooling and dehumidifying the air in the cabin. The process starts with the compressor drawing in low-pressure refrigerant gas from the evaporator and then compressing it into a high-pressure, high-temperature gas. This compressed gas is then sent to the condenser, where it releases heat and transforms into a high-pressure liquid. After leaving the condenser, the pressurized liquid refrigerant flows through the receiver drier or accumulator, which removes any moisture or debris from the refrigerant. From there, the refrigerant passes through the expansion valve or orifice tube, which regulates the flow of the refrigerant into the evaporator. Inside the evaporator, the high-pressure liquid refrigerant rapidly expands and evaporates, absorbing heat from the air passing over the evaporator's fins. This cools the air and reduces its humidity. The cooled air is then blown into the cabin through the vents, providing a comfortable and refreshing environment for passengers. Overall, the compressor plays a crucial role in the refrigeration cycle of the air conditioning system, ensuring that the refrigerant is properly circulated, pressurized, and transformed to achieve effective cooling inside the vehicle.
