Mystique V6-153 2.5L DOHC VIN L SFI (1999)
Evaporator Core: Description and Operation
POSITION IN THE REFRIGERANT CIRCUIT
On the low pressure side between the fixed orifice tube and the suction accumulator.
FUNCTION
Cooling, drying and cleaning the air.
CONSTRUCTION AND OPERATION
The evaporator is mounted in the evaporator housing behind the heater/air conditioning blower and operates like a heat exchanger. It consists of
numerous cooling coils which are connected by fins.
The refrigerant metered by the fixed orifice tube is sprayed as a low pressure liquid into the evaporator. As soon as the refrigerant comes into
contact with the inner surface of the cooling coils it vaporizes and extracts heat from the coils. The cooling coils and the entire evaporator undergo
considerable cooling. The vaporous refrigerant is then drawn in by the compressor.
The air flowing through the evaporator is cooled and dried and fed into the passenger compartment by the heater/air conditioning blower.
At the same time any moisture released is precipitated on the evaporator fins and condenses. The condensed water is drawn off through a drainage
line. Any dust or pollen particles stuck to the evaporator are washed away during this process. As a result, the air is cleaned and dried.
