24V Universal Air Conditioning Auto AC Compressor For 5S14 8PK WXUN076

Parameter:

Symptoms of a bad AC compressor include:

1.Lack of cooling: If the air conditioning system is not cooling the car's interior, it could be a sign of a faulty compressor. A worn-out or damaged compressor may have difficulty regulating the refrigerant flow necessary for effective cooling.

2.Warm air blowing: When the AC compressor is not working properly, hot air may be blown from the vents instead of cool air. This is a clear indication that the compressor needs to be repaired or replaced.

3.Weak or no airflow: Another symptom of a bad compressor is weak or no airflow from the AC vents. This could be due to a malfunctioning compressor not being able to generate sufficient air pressure.

4.Unusual noises: A loud clattering or rattling noise coming from the air conditioner when it's turned on is indicative of a problem with the compressor. This noise can occur when one or more components of the compressor assembly are broken or damaged.

5. Fluid leakage: Leaking fluid from the AC compressor is a clear sign of a malfunction. The compressor has bearings that prevent fluid leakage, but if these bearings become worn out or damaged, fluid can start to leak. Refrigerant leakage can cause the AC system to stop working and may also pose health risks. If any of these symptoms are experienced, it is recommended to have the AC compressor inspected and repaired by a qualified technician.

Working Principle

The AC compressor is a crucial component of the air conditioning system in your vehicle. It works by compressing the refrigerant vapor, which allows it to circulate and release cold air. The AC compressor is typically attached to the front of the engine using a bracket. It is powered by a belt that drives the compressor's pulley. When you turn on the AC, the AC compressor clutch engages, activating the compressor. This allows the compressor to compress the refrigerant vapor and convert it into a high-pressure gas. When the AC is not in use, the compressor pulley free spins, meaning it does not engage with the compressor. This can result in better gas mileage since the engine does not have to power the compressor. If either the compressor or the clutch fails, you may hear strange noises such as squealing or grinding coming from under the hood when you try to use the AC. This indicates a potential issue that should be addressed to ensure proper functioning of the air conditioning system.
