Evaporator Core: Description and Operation
A/C Evaporator Core
NOTE: Whenever an A/C evaporator core is replaced, it is necessary to also replace the suction accumulator/drier.
The A/C evaporator core is a multi-pass plate/fin aluminum core. The condenser to evaporator tube inlet connects to the bottom of the A/C evaporator
core. The suction accumulator/drier outlet connects to the top of the A/C evaporator core.
The A/C cycling switch senses pressure within the suction accumulator/drier and controls A/C compressor operation to regulate the pressure and
temperature within the A/C evaporator core.
The auxiliary A/C-heater system uses a rear-mounted A/C evaporator core which operates in the same manner as the manual A/C system.
