Does Condensation Water in Underground Garages Affect Cars?
2 Answers
Condensation water in underground garages does affect cars. More information about condensation water is as follows: 1. Formation: Condensation water forms when the air state during processing exceeds saturation humidity, and the water vapor partial pressure is higher than the saturation pressure, causing small water droplets to separate out. 2. Determination: Whether condensation water will form can be determined by consulting a psychrometric chart. Under air-cooled conditions, the line between the highest temperature point and the air supply state point should not intersect the saturation curve. In duct cooling conditions, the highest temperature point reaches the processed temperature via an isohumid line, which is an adiabatic dehumidification process, and should not cross the saturation curve during this period.
I've personally experienced significant issues with condensation in my underground parking garage. Moisture condenses on the underside and chassis of the car, which can easily lead to metal rust and corrosion, especially on brake lines and exhaust pipes. During my last maintenance check, the technician found rust spots on the chassis—if left untreated, this could accelerate part aging and increase repair costs. Additionally, the damp environment can cause electrical connectors to short-circuit, affecting lights or the ignition system. I recommend keeping the garage door open for ventilation or using a dehumidifier, and wiping down areas prone to water accumulation, like around the wheels, after parking. Regularly checking the chassis seals or applying anti-rust coatings can significantly reduce risks. For safety's sake, don't overlook garage humidity—it can quietly ruin your car.
