8103100XS56XB 12V Air Conditioner Compressor JSR09T 4PK For The Great Wall Hover M4 WXCC027

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.

The Five Major Parts Of Your Car’s A/C System

COMPRESSOR
The compressor is the most vital component in any air conditioning system, ensuring that you get cool air. It performs four key functions in your vehicle:

• Pressurizing the refrigerant to cool the air
• Detecting temperature changes inside and outside the car
• Regulating and managing temperature output
• Pushing air to the condenser

CONDENSER
The A/C condenser is typically located in front of the radiator, often referred to as a mini-radiator. While the compressor pressurizes the refrigerant, the condenser cools and lowers the pressure of the hot gases from the refrigerant. It also moves the cooled liquid refrigerant to the receiver/dryer or accumulator.
RECEIVER/DRYER OR ACCUMULATOR
Your vehicle will either have a receiver/dryer or an accumulator, depending on the model. Cars with a thermal expansion valve have a receiver/dryer, while those with an orifice tube feature an accumulator.

• The receiver/dryer separates gas from liquid to protect the compressor, which is only built to handle gases. It also removes moisture with a desiccant, similar to the bead-filled packets found in electronics packaging, and includes filters to protect the A/C system from contaminants.
• The accumulator controls how much refrigerant goes into the evaporator, stores excess refrigerant, filters debris, and eliminates moisture.

THERMAL EXPANSION VALVE OR ORIFICE TUBE
As mentioned, vehicles with a thermal expansion valve use a receiver/dryer, while those with an orifice tube have an accumulator. These components, found between the condenser and evaporator, regulate pressure and temperature and determine the appropriate amount of refrigerant to enter the evaporator.
EVAPORATOR
The evaporator is essential for producing the cold air that cools your cabin. Located behind the dashboard, it cools the air with refrigerant before it’s circulated into the interior of your vehicle.

If Compressor Noises from Under the Hood

When unusual noises arise from your vehicle, particularly concerning the air conditioning system, it is usually an indication of a problem. This includes the AC compressor, which has the crucial task of compressing and circulating the refrigerant for the air conditioning. During your daily driving, the compressor regularly goes through cycles of turning on and off, causing wear and tear on its components over time.

One common issue is with the sealed bearing within the AC compressor, which can deteriorate or seize up when the lubricant leaks out. This can lead to a high-pitched squeal or a grinding noise resembling metal-on-metal. If the bearing seizes, the drive belt may emit a squealing sound as it fails to rotate the compressor.

Repairing AC compressors is sometimes possible, but in most cases, replacing the faulty compressor with a new one is a more effective and durable solution. Not only does this save time, but it also ensures a higher-quality repair.
