Evaporator Core: Description and Operation
EVAPORATOR CORE
NOTE:
-
Installation of a new receiver/drier is not required when repairing the air conditioning system, except when there is physical evidence of
contamination from a failed A/C compressor or damage to the receiver/drier.
-
A second (auxiliary) evaporator core is used for HVTB cooling on hybrid vehicles. For information concerning the auxiliary evaporator core, refer
to Heating and Air Conditioning.
The evaporator core is an aluminum plate/fin-type and is located in the heater core and evaporator core housing. A mixture of liquid refrigerant and oil
enters the bottom of the evaporator core through the evaporator core inlet tube and continues out of the evaporator core through the evaporator core
outlet tube as a vapor. During A/C compressor operation, airflow from the blower motor is cooled and dehumidified as it flows through the evaporator
core fins.
