Working principle for AC car compressor

In a closed AC system, the cooling of freon in the evaporator occurs due to a sharp change in pressure: liquid freon under high pressure passes through a narrow opening, atomizing and instantly cooling.
 
The task of the compressor is to pump refrigerant (freon) from the low-pressure circuit (from the condenser radiator) to the high-pressure circuit (to the evaporator radiator) with its simultaneous compression, which means an increase in temperature. In the condenser, the freon is cooled and turns into a liquid state, after which it enters the condenser again.
 
The AC compressor is sometimes referred to as the "heart" of the system, so its smooth operation is so important for the normal operation of the air conditioner. At the same time, the compressor is also heavily loaded.
 

Goods Picture

 
 
When an automotive air conditioning compressor is damaged, it can manifest in various signs and symptoms. Here are some common indications of compressor damage:
 
1. Lack of cooling: One of the primary signs of a faulty compressor is a decrease in the cooling capacity of the air conditioning system. The air blown into the cabin may not be as cold as it used to be. This can be attributed to a lack of compression and reduced refrigerant circulation.
 
2. Loud noises: A damaged compressor may produce unusual and loud noises during operation. These noises can include grinding, squealing, or rattling sounds. Such sounds indicate internal mechanical issues or loose components within the compressor.
 
3. Leaking refrigerant: If you notice refrigerant leaking from the compressor or any other component of the AC system, it can indicate compressor damage. Leaks are often caused by worn-out seals or cracks in the compressor housing, resulting in a loss of refrigerant.
 
4. Excessive vibration: A damaged compressor may cause abnormal vibrations in the vehicle. These vibrations can be felt through the steering wheel, dashboard, or entire cabin. Excessive vibration can indicate internal damage or misalignment of compressor components.
 
5. AC system failure: In severe cases, a damaged compressor can lead to a complete failure of the air conditioning system. The compressor may seize, preventing any refrigerant circulation and resulting in no cooling at all.
 
If any of these signs are observed, it is advisable to have the compressor inspected and repaired by a certified technician. Prompt attention to compressor damage can prevent further damage to the AC system and ensure optimal cooling performance in the vehicle

9 Reasons Your Car AC Compressor Might Fail

Refrigerant Leaks
As time passes, the seals in your AC system may deteriorate, leading to refrigerant leaks. These seals are essential for keeping the AC system tightly sealed, and when they wear down, refrigerant can escape, reducing your AC's cooling performance.
Additionally, accidents or impacts to your vehicle can cause damage to AC components, leading to leaks. Even small collisions or debris hitting the AC parts can result in refrigerant leaks, eventually affecting the compressor.
Contaminants
Moisture can infiltrate the AC system, causing corrosion and potentially damaging the compressor. Moisture is harmful to the AC system as it can chemically react with the refrigerant, forming corrosive acids that harm the compressor. Furthermore, dust, dirt, or debris can accumulate within the system, affecting compressor function. These contaminants can block filters, obstruct expansion valves, and lead to poor compressor performance.
Excessive Pressure
Blockages in the expansion valve or orifice tube can create high-pressure conditions that put stress on the compressor. When these parts become blocked, refrigerant flow is restricted, causing pressure buildup in the system that can harm the compressor. Additionally, adding too much refrigerant can result in excessive pressure, which can also damage the compressor. Overcharging often occurs due to DIY refrigerant additions or unskilled service work.

Lack of Lubrication

Without proper lubrication, compressor components can experience friction and wear. The compressor relies on a specific type and amount of oil for smooth operation. Insufficient oil levels can lead to premature wear and failure. Leaks in the oil supply can also deprive the compressor of essential lubrication. Oil leaks within the AC system can reduce lubrication, causing damage to moving parts within the compressor.

Age and Wear

Like all mechanical parts, AC compressors have a finite lifespan and can wear out due to regular use. Over time, the compressor’s internal components can experience wear and tear, leading to decreased efficiency or outright failure.

Electrical Issues

Issues with the AC clutch, such as a worn-out clutch plate or faulty wiring, can prevent the compressor from engaging. The clutch is responsible for engaging and disengaging the compressor. If it malfunctions, the compressor won’t function properly.

Poor Maintenance

Neglecting to change the cabin air filter or clean AC components can lead to compressor strain. Accumulated dirt and debris within the system can impede airflow, causing the compressor to work harder. Failing to check and replace refrigerant as needed can affect the compressor’s performance. Regular refrigerant checks and maintenance are essential to keep the compressor operating optimally.

Excessive Use

Running the AC system at high settings and for extended periods can lead to premature compressor wear. Prolonged use at high cooling levels can stress the compressor more, potentially reducing its lifespan.

Environmental Factors

Very hot or cold weather conditions can place additional stress on the compressor, impacting its performance and longevity. Extreme temperatures can cause the compressor to work harder, potentially leading to wear and tear.
