As the sweltering heat approaches, the steering wheel becomes scorching hot to the touch, making car air conditioning an essential for travel.
If the air conditioning doesn't cool, the interior environment becomes like a furnace, unbearably hot.
The air conditioning compressor, expansion valve, and air conditioning pipes, as important components of the car air conditioning system,
work together to achieve the cooling and heating functions of the car air conditioning.
This article will delve into the common faults of these components and how to maintain them.
(1) Air Conditioning Compressor Failure
Failure of the air conditioning compressor is a common fault that can result in poor cooling or even no cooling at all. It is easy for car owners to notice that the temperature of the air conditioning outlet is not cold enough, or even no cooling at all. This phenomenon may be due to the compressor itself (such as internal parts wear, motor damage), or it may be related to other system issues such as insufficient refrigerant or poor condenser heat dissipation. In addition, compressor failure may also produce abnormal noises, such as "buzzing," whistling, or other unusual sounds, affecting the driving experience.
Maintenance Suggestions
It is recommended to replace with a NIBD air conditioning compressor.
Advantages
Electromagnetic Valve: Specifically designed for high-end OEM applications, it offers precise control and ensures stable cooling performance.
Piston: Coated with polytetrafluoroethylene (PTFE), it achieves low noise, low vibration, and high durability. The larger single-cylinder capacity of the piston significantly improves cooling efficiency.
Electromagnetic Clutch: Equipped with a fusible link and diode, it reduces noise and vibration while providing overload protection to ensure safe belt operation.
(2) Expansion Valve Failure
The expansion valve may also have some minor issues, such as clogged valve ports or unresponsive opening and closing. When the valve port is clogged, the flow of refrigerant will be obstructed, leading to a decrease in cooling capacity.
If the expansion valve has unresponsive opening and closing, it will not be able to accurately regulate the refrigerant flow according to the changes in cooling load, which will also affect the air conditioning cooling effect and cause unstable cabin temperature.
Maintenance Suggestions
Replace with a NIBD expansion valve.
Advantages
OE Matching Characteristics: The specially designed flow control valve meets specific system requirements and offers reliable superheat regulation.
Compact Design: Ensures the smoothness of internal precision components, allowing for quick and stable installation.
(3) Air Conditioning Pipe Leakage
Leakage is one of the most common faults of air conditioning pipes. Car owners may notice a decrease in air conditioning cooling efficiency, and see oil stains or refrigerant leakage marks at the air conditioning pipe connections or on the surface of the pipes. In addition, the inside of the air conditioning pipe may be blocked by impurities, oil stains, or foreign matter in the refrigerant. Moreover, the air conditioning pipe may be deformed or flattened during installation or use due to external forces.
Maintenance Suggestions
Replace with NIBD air conditioning pipes.
Advantages
OE-Quality Hoses: Manufactured by the same factories that supply OEM parts, ensuring high-quality and reliable performance.
Sealing Rings: Made from the same materials used in original vehicles, these rings are corrosion-resistant and wear-resistant, offering a long service life and excellent sealing performance.
Original Appearance and Fit: The hoses match the original vehicle design and are manufactured using the same crimping processes as the OEM, ensuring a perfect fit.
NIBD Reminds You
The car air conditioning system is a crucial component for the normal operation of the vehicle. Regular inspection and maintenance are essential. Ignoring these maintenance measures may lead to reduced cooling efficiency, affecting driving comfort and even posing safety risks.
