Basic Climate Control
•
The condensed water that forms on the surface of the evaporator comes from the
moisture in the air passing through the fins of the evaporator. The moisture being
removed from the air also has the added benefit of reducing the relative humidity of the
air entering the vehicle. The moisture collected on the fins of the evaporator will drain off,
and leave the vehicle through the drain tube. It is normal that during operation of the A/C
a pool of water may appear underneath the vehicle.
•
If the condensed water on the surface of the evaporator does begin to freeze, then it
could lead to reduced cooling by restricting the airflow. The evaporator temperature
sensor makes sure that the condensed water does not freeze. The function of the sensor
is covered in the Advanced Climate Control course.
