Can a Car Compressor Still Be Used After Water Intrusion?
2 Answers
Water entering the interior of the compressor pump can cause oxidation of internal components, leading to rust or copper plating. If a large amount of water enters, the compressor will be unable to cool. Below is relevant information: 1. Treatment Method: If the water intrusion time is short and the amount is small, the compressor can be disassembled for cleaning. Generally, components are oil-immersed during manufacturing, so the likelihood of oxidation is low. After cleaning and reassembly, the compressor can continue to be used after refilling with oil. 2. Compressor: A compressor is a type of driven fluid machinery that elevates low-pressure gas to high-pressure gas, serving as the heart of the refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it via piston movement driven by the motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle.
I've seen many cases of water entering the compressor, which usually renders it unusable. The air conditioning compressor contains precision components and specialized lubricating oil. Once water enters, it mixes with the oil, causing loss of lubrication, accelerated wear, and corrosion. More seriously, water is incompressible, and forcing the compressor to run can lead to seizure or motor burnout, damaging the entire AC system or even the engine belt. I remember a customer whose car was flooded during a heavy rainstorm. He continued to use the AC for cooling, resulting in a seized compressor. It took us half a day to dismantle and clean the system, but we ended up replacing the compressor. Recommendation: If water ingress is suspected, immediately stop using the AC and have the car towed to a professional workshop for inspection. For prevention, try to avoid deep water areas and park on higher ground.
