4.4 Electronic Expansion Valve
• The electronic expansion valve causes rapid
refrigerant expansion by injecting "high-
temperature, high-pressure liquid refrigerant"
from the condenser through a small orifice. The
resultant "low-temperature, low-pressure mist
refrigerant" is then sent to the evaporator. A
solenoid valve adjusts the refrigerant quantity
according to the evaporator pipe inlet
thermistor and pipe outlet thermistor such that
the mist refrigerant can undergo heat
exchange in the evaporator under optimal
conditions.
4.5 Evaporator
• The evaporator is a heat exchanger covered
with plate fins. Heat is removed from the air
being pulled across the evaporator by the
centrifugal fan. The resulting cool air is
expelled through the cool air vent.
