What Causes Refrigerant Leakage in Car Air Conditioning?
2 Answers
The most common causes of refrigerant leakage in car air conditioning are damaged seals or excessively cold air. Here are the details: 1. Refrigerant leakage issue: Typically caused by leaks due to damaged pipe joint seals, which can be resolved by replacing the seal rings. However, in actual repair work, it can be difficult to immediately locate the fault point for minor leaks. Sometimes, parts need to be replaced to identify the issue, but the fault point generally does not appear in multiple components, so they can be replaced one by one to locate the problem. 2. Excessively cold air: Moisture in the air can condense at the outlets. Continuously using the outside air circulation function allows high-humidity outside air to constantly enter the car, and the humidity inside cannot be discharged outside, leading to this issue.
I think refrigerant leakage in car air conditioning is quite a common issue, and I've encountered it several times. The most common causes are aging/loose connections or worn-out seals. Over time, the rubber seals at pipe joints tend to harden and crack, causing the refrigerant to leak gradually. Also, if the compressor or condenser pipes weren't installed properly during repairs, gaps can form leading to leaks. Additionally, bumpy summer roads create vibrations that loosen pipe joints more easily. When the AC cooling performance drops noticeably, you should suspect a leak. I recommend getting it checked at a professional shop soon using fluorescent dye to locate leaks. Otherwise, prolonged leakage not only reduces cooling but also releases harmful gases from the refrigerant, which is bad for the environment. Regular maintenance can significantly prevent such troubles.
