Measuring Superheat

Where possible, always select a thermal expansion valve for the actual operating conditions rather than nominal valve capacities.

To determine the valve is working properly is by measuring its superheat.

The degree to which the refrigerant gas is superheated depends on
1) the amount of refrigerant being fed to the evaporator by the valve
2) the heat load to which the evaporator is exposed.
