Evaporator Core: Description and Operation
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 and the suction accumulator/drier (inlet) connects to the top of the A/C evaporator core. The outlet of the accumulator/drier then connects to the
evaporator to compressor suction line. The evaporator tube is fitted with an A/C evaporator core orifice to control refrigerant flow. This A/C evaporator
core orifice can be removed from the evaporator core inlet tube for replacement if it becomes necessary. However. a special tool is necessary to prevent
breakage of the A/C evaporator core orifice.
