- Expansion Valve
-
- The expansion valve
- lowers the pressure
- of the refrigerant
- and decides how
- much to send to the
- evaporator. The
- expansion valve
- opens when the
- compressor starts
- and forces the high
- pressure liquid
- through a screen to
- strain it. Once
- inside the
- expansion valve,
- the refrigerant is
- brought to the
- correct pressure
- keeping the balance
- correct between the
- heat load and the
- efficiency of the
- evaporator. When
- more refrigerant is
- called for, the
- expansion valve
- opens to allow more
- refrigerant into
- the evaporator's
- coils.
