3. to heat to an extreme degree or to a very high temperature.
4. to heat (a liquid) above its boiling point without the formation of bubbles of vapor.
5. to heat (a gas, as steam not in contact with water) to such a degree that its temperature may be lowered or its pressure increased without the conversion of any of the gas into liquid.
A Martian came across the fields about midday, laying the stuff with a jet of superheated steam that hissed against the walls, smashed all the windows it touched, and scalded the curate's hand as he fled out of the front room.
Into this he thrust the blade of his stone knife, and as it became superheated he would withdraw it, touching a spot near the thin edge with a drop of moisture.
In addition, the temperature of the cold storage room is one of the most important controlled parameters, and the control of the evaporator outlet superheat is an important way to improve the stability and efficiency of the refrigeration system.
The relationship between the various actuators (valve, compressor, fans) and the measured outputs (evaporator superheat, cooling/heating load, operating pressures) are fully coupled.
The use of electronically controlled expansion devices is becoming more popular, especially in higher efficiency units as this allows for programmable control of the superheat in many operating modes.
