new size of refrigerator what is the sizes of coils

[nike123]

hi Mr. josip
I HAVE SOME QUESTIONS
RECENTLY OIM STUDTY THE COP IM CONFUESED ABOUT COP

COP

Carnot = Te / (Tc - Te)

how could i find these values

according to Te is evaportor temp
Tc = condensor temp
next question is

COP =Cooling effect (kW)/
Power input to compressor (kW)

cooling effect in KW ???????
HOW TO CONVERD temp TO IN KW
PLEASE ANS ME

THANKS

Cooling effect of compressor in your text is actualy cooling capacity of compressor achieved by moving certain amount of refrigerant with certain evaporation and condensation temperature and could be found in catalog data of compressor.
In order to make work required for moving that refrigerant at that same evaporation and condensation temperatures, compressor motor need power which also could be found in catalog data of compressor.

Relation of refrigeration capacity expressed as cooling effect or cooling capacity in kW (or BTU or Tons of refrigeration), and
power consumed from motor to make work of compressor and expressed as power input of compressor in kW (or HP), is COP (coefficient of performance), and it tell us how efficient compressor (or system) it is.

If one compressor need 1 kWh of electric energy to produce cooling effect of 3 kWh than his COP is 3.

If other compressor ned 1 kWh of electric energy to produce cooling effect of 4 kWh than his COP is 4, and he is more efficient than other with COP of 3.

So one compressor have two power figures in same time,
one is consumed electrical power for compressor work and other is cooling power.
