Technical Engineering Guide & Field Diagnostic Practices

Superheat measures the sensible temperature increase of vapor refrigerant after it has completely boiled off in the evaporator coil. Adequate superheat guarantees that 100% dry vapor enters the compressor, preventing catastrophic liquid floodback which destroys valves, pistons, and scroll wraps.
