Evaporator Core: Description and Operation
Evaporator Core
NOTE: Installation of a new suction accumulator is not necessary when repairing the air conditioning system except when there is physical evidence of
system contamination from a failed A/C component or damage to the suction accumulator.
The evaporator housing contains the evaporator core. The evaporator core is the plate/fin type with a unique refrigerant flow path.
-
A mixture of refrigerant and oil enters the bottom of the evaporator core through the evaporator core in let tube and is routed so it flows through
the partitioned first four plate/fin sections.
-
The next four plate/fin sections are partitioned to force the refrigerant to flow toward the other end of the evaporator core.
-
The next five plate/fin sections are partitioned to force the refrigerant to flow toward the bottom of the evaporator core.
-
Refrigerant then continues through to the remaining five plate/fin sections and then moves out of the evaporator core through the evaporator core
outlet tube.
-
This W-pass flow pattern transfers the flow of refrigerant and oil through the evaporator core.
