Parameter:

 
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.
 

 
Testing:
 
1. Vacuum testing: Connect the vacuum pump to the low-pressure side of the refrigerant system using a manifold gauge set. Evacuate the system by running the vacuum pump for the recommended amount of time specified by the manufacturer. Monitor the gauge readings to ensure that the system holds a vacuum.
 
2. Leak testing: Once the vacuum is achieved, close the valves on the manifold gauge set and turn off the vacuum pump. Allow the system to sit for a period of time and monitor the gauge readings. If the gauge readings remain stable, it indicates that the system is leak-free. Any significant drop in gauge readings would suggest a refrigerant leak and require further investigation.
 
3. Operational testing: With the vacuum still intact, proceed to recharge the system with the appropriate amount of refrigerant. Start the engine and turn on the air conditioning. Monitor the compressor operation, including the clutch engagement and refrigerant pressure on the gauge set. Ensure that the compressor operates smoothly and provides the desired cooling effect.
 
4. Performance testing: Measure the air temperature at the vents using a thermometer. It should be significantly lower than the ambient temperature. If the cooling effect is not satisfactory, it may indicate an issue with the compressor or other components that require further diagnosis.
 
In conclusion, the proper installation and regular testing of car air conditioning compressors are crucial for maintaining optimal performance. By following the steps outlined above, you can ensure a successful installation and reliable operation of the compressor.
