Evaporator Core: Description and Operation
NOTE: Whenever an A/C evaporator core is replaced, also replace the suction accumulator/drier.
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 is routed so that it
flows through the partitioned first five and one half plate/fin sections.
^
The next five plate/fin sections are partitioned to force the refrigerant to flow toward the other end of the A/C evaporator core.
^
The refrigerant then continues over to the remaining six and one half plate/fin sections and then moves out of the A/C evaporator core through the
A/C evaporator core outlet tube.
^
This S-pass flow pattern accelerates the flow of refrigerant and oil through the A/C evaporator core.
