7-3. LEV
(1) Function
- It lowers the pressure of refrigerant, decreasing the temperature of the evaporator.
- It improves the efficiency of the compressor cycle.
- It adjusts the amount of refrigerant that flows into the evaporator.

ture and low pressure state by the LEV. As the low temperature
and low pressure refrigerant passes through the evaporator, it
side
absorbs the heat of the air coming from outside and turns into
gas. Meanwhile, the temperature of outside air decreases as
the evaporator performs heat exchange. For the reference, the
temperature of the evaporator can be controlled by the LEV.
