Evaporator Core: Description and Operation

Air Flow:

The evaporator core, which is aluminum and of a horizontal "U" flow design, is the actual cooling unit of the system. The blower forces air through the evaporator core where it is cooled and dehumidified. The liquid refrigerant in the evaporator core absorbs heat from the air stream, as it changes to a vapor. Condensate which forms on the cold evaporator core is drained from the module through a small hole in the bottom of the evaporator case.
