Will water drip under the chassis when the car's air conditioning is on?

[VanMason]

Water will appear under the chassis when the car's air conditioning is on. The details are as follows: 1. Function of the air conditioning drain outlet: During air conditioning operation, the evaporator continuously absorbs heat and condenses moisture from the surrounding air into water during the heat exchange process. This water is discharged through the air conditioning drain outlet, which is why a puddle of water appears under the car after the air conditioning has been running for a while. You only need to check whether the car's air conditioning is on. 2. Water accumulation: The car's air conditioning produces condensate during the cooling process, and the condensate drain pipe is located under the chassis. During the rainy season, passing through mud or standing water can also block the drain hole, leading to the same consequences as a blocked engine compartment drain hole—water may flow back into the car, causing water accumulation on the floor.
