Evaporator Core: Description and Operation
Evaporator - LHD Shown, RHD Typical
The evaporator is located in the HVAC housing, behind the instrument panel. The evaporator is positioned in the housing so that all air that enters the
housing must pass over the fins of the evaporator coils before it is distributed through the system ducts and outlets. However, air passing over the
evaporator fins will only be conditioned when the compressor is engaged and circulating refrigerant through the evaporator tubes.
Refrigerant enters the evaporator from the variable orifice valve as a low-temperature, low-pressure liquid. As air flows over the fins of the evaporator,
the humidity in the air condenses on the fins, and the heat from the air is absorbed by the refrigerant. Heat absorption causes the refrigerant to boil and
vaporize. The refrigerant becomes a low-pressure gas when it leaves the evaporator.
The evaporator cannot be repaired and, if faulty or damaged, it must be replaced.
