Why Are There Water Droplets at the Car Air Conditioning Vents?

[VonEvelyn]

The reasons for water droplets at the car air conditioning vents are as follows: 1. The air conditioning is set too low: When the air conditioning is set too low, moisture in the air condenses on the outside of the vents, creating a phenomenon resembling white smoke. Moisture in the air can also condense on the plastic casing of the evaporator or the outer surface of the plastic ducts delivering cold air, leading to dripping. 2. Evaporator: Models with poor insulation on the plastic casing of the evaporator or the plastic ducts delivering cold air are more prone to this issue. 3. Poor vehicle airtightness: High-humidity outside air continuously seeps into the car interior. Another typical symptom of excessively high humidity inside the car is the condensation of water droplets around the vents.
