Evaporator Core: Description and Operation
A/C EVAPORATOR CORE
NOTE:
-
The evaporator core is not separately serviceable, it is serviced only with the evaporator core housing assembly.
-
Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of
system contamination from a failed A/C compressor or damage to the suction accumulator.
The A/C evaporator core is the plate/fin type with a unique refrigerant flow path.
-
A mixture of refrigerant and oil enters the bottom of the A/C evaporator core through the A/C evaporator core inlet tube and then moves out of the
A/C evaporator core through the A/C evaporator core outlet tube.
-
This flow pattern accelerates the flow of refrigerant and oil through the A/C evaporator core.
