Answer / ajit singh

the temp. below the saturation temp. of liquid is subcooled
temp.and the temp.above the saturation temp. of vapour is
called superheted.

Answer / mohammed sohail.s

subcooling - reducing the temperature below freezing point
of that substance.

superheating - raising temperature above boiling point of
that substance

Answer / al domingo

Subcooling - in the system condenser,conversion of vapor to
liquid involves removing heat from the refrigerant at its
saturation condensing temperature...any additional
temprature decrease is called
subcooling.
superheat - in the system evaporator,conversion of liquid
to vapor involves adding heat to the liquid at is boiling
temperature,commonly to as saturation temperature..

Answer / a. chinna hanumanthu

subcooling means reducing the temperature below the saturation liquid temperature.
super heating means inceasing the temperature above the staturated vapour temperature

Answer / techyy

Sensible cooling below saturation liquid condition at that
pressure and temperature is sub-cooling & sensible heating
beyond saturation vapour condition at that pressure and
temperature is super-heating.

Answer / fowzel

sub cooling means cooling at pre state and super heating means
heating beyond critical temperature

Answer / 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
