Is It Normal for a Car's Air Conditioning to Produce Excessive Condensation Water?

[StLucy]

Excessive water drainage from a car's air conditioning system is a normal phenomenon as long as the water is condensation. In fact, more water drainage indicates better cooling performance of the car's air conditioning. Below is relevant information about car air conditioning condensation water: Under normal circumstances, there is a dedicated drainage pipe located beneath the front passenger seat, through which the condensation water is discharged. When the air conditioning is in cooling mode, the temperature of the evaporator and the air ducts leading to the passenger compartment becomes very low, typically around 0~5 degrees Celsius. At this point, water vapor from the outside air condenses on the pipe walls and housing of the air conditioning system due to the low temperature. This condensation water must be drained promptly; otherwise, it may lead to corrosion of surrounding components.
