Evaporator Core: Description and Operation
Description
DESCRIPTION
NOTE: LHD model shown. RHD model similar.
The A/C evaporator (1) for the heating-A/C system is located within the HVAC housing, behind the instrument panel. The A/C evaporator and insulator
(2) are positioned in the HVAC housing so that all air entering the housing must pass over the evaporator fins before it is distributed through the
heating-A/C system ducts and outlets. However, air passing over the evaporator fins will only be conditioned when the A/C compressor is engaged and
circulating refrigerant through the A/C evaporator.
The A/C evaporator tubes (3) are connected and sealed to the A/C expansion valve by use of rubber O-rings (4) and a tapping block (5).
The A/C evaporator can only be serviced by removing and disassembling the HVAC housing assembly.
