In a refrigerator the power rating impressed on the compressor is 1.2 kW. The circulating wire in evaporator is 5 kW and the cooling water took away 10 kW from condenser coil. The operating temperatures range is 18ºC and 0ºC and their corresponding latent heats are 170 kJ/kg and 230 kJ/kg and the difference between the liquid energy is 35 kJ/kg. Find the actual COP of the system (2) relative COP, assuming the vapor is just dry and saturated at the end of the compression.

Question
In a refrigerator the power rating impressed on the compressor is 1.2 kW. The
circulating wire in evaporator is 5 kW and the cooling water took away 10 kW from
condenser coil. The operating temperatures range is 18ºC and 0ºC and their
corresponding latent heats are 170 kJ/kg and 230 kJ/kg and the difference between the
liquid energy is 35 kJ/kg. Find the actual COP of the system (2) relative COP, assuming
the vapor is just dry and saturated at the end of the compression.
