The role of compressor

The compressor is an essential component of the air conditioning system in a vehicle. Its primary function is to circulate and compress the refrigerant gas, which is responsible for cooling and dehumidifying the air in the cabin. The process starts with the compressor drawing in low-pressure refrigerant gas from the evaporator and then compressing it into a high-pressure, high-temperature gas.

This compressed gas is then sent to the condenser, where it releases heat and transforms into a high-pressure liquid. After leaving the condenser, the pressurized liquid refrigerant flows through the receiver drier or accumulator, which removes any moisture or debris from the refrigerant.

From there, the refrigerant passes through the expansion valve or orifice tube, which regulates the flow of the refrigerant into the evaporator. Inside the evaporator, the high-pressure liquid refrigerant rapidly expands and evaporates, absorbing heat from the air passing over the evaporator's fins. This cools the air and reduces its humidity.

The cooled air is then blown into the cabin through the vents, providing a comfortable and refreshing environment for passengers. Overall, the compressor plays a crucial role in the refrigeration cycle of the air conditioning system, ensuring that the refrigerant is properly circulated, pressurized, and transformed to achieve effective cooling inside the vehicle.

Compressor failure status

In the case of leaks, refrigerant can escape the system through various points such as the shaft seal, hoses, O-rings, and gaskets. These leaks can be difficult to identify and may require the use of UV dye or electronic leak detectors. When refrigerant leaks, it not only affects the compressor but can also damage other components in the system. The refrigerant carries an oil mist that helps keep everything lubricated, so insufficient refrigerant can disrupt the air conditioning cycle and cause damage.

Odd noises coming from the compressor can be a result of internal parts failing or seizing. This can lead to unpleasant sounds, especially from the compressor clutch or belt pulley.

If the air conditioner is not producing cool air, it's likely due to a lack of refrigerant or a failing component in the system. Insufficient refrigerant prevents the compressor from circulating enough refrigerant to maintain proper cooling.

If the check engine light on the dashboard is illuminated, it indicates a more serious issue. The ECU (Engine Control Unit) monitors voltage signals to various parts, including the compressor. Malfunctioning signals can result in incorrect voltage delivery, triggering the check engine light.
