Sub-cooling
in a vapour compression refrigeration system ________enthalpy of liquid
refrigerant below saturation level.

In Vapour
Compression Refrigeration System (VCRS), during sub-cooling to increase
efficiency of cycle we drop the temperature of the fluid below saturated liquid
line, because of which we observe thedecrease in enthalpy.
i.e. from the
figure
Means there is drop in enthalpy.
Hence, the correct option is (A).
&Key Points:-
For sub-cooling
to be done, generally the condenser coils are extended and given a larger
magnitude of length.
