Heat rejected = Heat taken from Evaporator + heat rejected from compressor.
Here heat Rejected is given as summation of RE+ W ( Compressor).
Now COP = RE/Work.
= 120 - 30/30 = 3.

= 120 - 30/30 = 3.

C.O.P = heat/workdone,
=> 120/30,
=> 4.
=> 120/30,
=> 4.

cop = ref effect / work done.
= 120 - 30 / 30.
= 3.
= 120 - 30 / 30.
= 3.

Refrigeration effect = 120-30 = 90.
cop = 90/30 = 3.
cop = 90/30 = 3.
