SWJ7B08 Vehicle Air Conditioner Compressor For Perodua Kancil ND For Kelisa WXDH028

 The automobile air conditioning compressor is the core component of the automobile air conditioning system and plays a key role in driving the refrigeration cycle. It achieves rapid cooling of the air in the car by compressing low-pressure cold gas into high-pressure and high-temperature gas. A high-quality compressor provides efficient refrigeration capacity, which can reduce the temperature inside the car in a short time and provide a comfortable driving experience. At the same time, it must have the characteristics of low energy consumption, low noise and reliability to ensure the long-term stable operation of the air conditioning system. The performance of the automobile air conditioning compressor directly affects the working effect of the entire air conditioning system. Choosing a high-performance and reliable compressor will bring a more comfortable driving experience to the driver.

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.
 
 
 
 
Indications of a Defective Car Air Conditioning System
 
1.Insufficient Airflow: Insufficient or weak airflow from the vents is often a sign of AC trouble. It can suggest issues with the blower motor, obstructed air filters, or blocked ducts. Reduced airflow can lead to insufficient cooling and discomfort inside the vehicle.
 
2.Unusual Sounds: Uncommon noises coming from the AC system, like rattling, squealing, or grinding sounds, should not be ignored. These noises can be indicative of problems with the AC compressor, fan, or other components. Neglecting these sounds can result in further damage and potential system failure.
 
3.Unpleasant Smells: Foul or musty odors coming from the AC vents can indicate mold or bacterial growth within the system. Moisture buildup or clogged drains can contribute to this issue. The presence of unpleasant smells not only diminishes the driving experience but can also affect air quality and potentially cause health issues.
 
4.Inconsistent Cooling: If the AC system fails to maintain a consistent and comfortable temperature, it may indicate low refrigerant levels, a leak, or a malfunctioning compressor. Inconsistent cooling can make the driving environment uncomfortable, especially during hot weather conditions.
