The Thermo Expansion valve is a precision device designed
to meter the flow of refrigerant into an evaporator in exact
proportion to the rate of evaporation of the refrigerant in the
evaporator.
The Thermo Expansion valve can control the refrigerant gas
leaving the evaporator at a pre-determined superheat.
The superheat is the temperature difference between T1
(Temperature measured at remote bulb location) and P2
(Evaporation temperature of the last liquid drop).
T1 : Temperature at remote bulb location
P2 : Evaporator outlet pressure
S : Superheat
