What is full form of C.O.P?

Its "coefficient of performance".

Can you explain it why cop is increased?

Elango said: (Oct 8, 2015)  
If sub cooling has to be done therefore heat input will also be more therefore refrigerating effect gets increased.

As we know cop is the ratio of refrigerating effect by work done and refrigerating effect increases therefore cop increases.

Cop will decrease.

Draw VCRS, the RE increases and work remains constant. c.o.p is RE/WD so cop increase.

Subcooling refers to a liquid existing at a temperature below its normal boiling point.

Lakshminarasimha said: (Jul 21, 2018)  
Subcooling increases, the COP reaches a maximum as a result of a trade-off between increasing refrigerating effect and specific compression work. Refrigerants with large latent heat of vaporization tend to benefit less from condenser.

Due to subcooling of refrigerant there is increase in refrigerating effect but work input remains same hence C.O.P. increases.
