Indications
EER Energy Efficiency Ratio = W rendered/ W absorbed (could also be: frig/h / W absorbed)
COP Coefficient of performance: effectiveness - pure dimensionless number
The COP assumes different connotation depending on whether the refrigerating cycle is responsible for the production of cold or heat production (heat pump). The COP and do not constitute the EER performance and are therefore always greater than 1. They define only the degree of heat transfer for each unit of energy supplied from the outside.
 
COP  for the production of cold:
It can be determined on the pressure-enthalpy diagram taking the ratio between the refrigerating effect and the thermal equivalent of the compression work:
 
  COP = cooling effect/heat compression
COP  for the cycle of the heat pump:
In this case, the required effect is heating. Then you must consider the sum of the effect refrigerator and the thermal equivalent of the compression work, which constitutes the available heat. It must be divided by the thermal equivalent of the compression work:
 
  COP = cooling effect/heat compression              
Note that certain texts report the COP as the ratio of: Power output/power consumption in the same way EER
