difference between sub cooling super heating
Answer Posted / rajasimha
Sub cooling is Cooling below the required temperature where
as super heating is heating above the required temperature.
Eg.
If a liquid has to be cooled to -10 degree Celsius but it is
cooled to -20 degree Celsius then it is sub cooling.
If a gas has to be heated to 100 degree Celsius but it is
heated to 110 degree Celsius them it is super heating.
Super heating generally increases efficiency ( Steam power
plants) but sub cooling is not generally not desired
