The cooling COP input field for both [single-speed](https://bigladdersoftware.com/epx/docs/9-3/input-output-reference/group-heating-and-cooling-coils.html#field-gross-rated-cooling-cop and multi-speed coils account for electricity use of both the compressor and condenser fan. EnergyPlus already generates an output variable for Cooling Coil Electric Power that is the electricity use of both the compressor and condenser fan. So, you could modify the COP input to remove the electricity use of the condenser fan so that the output variable only accounts for the electricity use of the compressor. However, to do this accurately, you should also update the three performance curves related to changes in COP over the simulation:

Preface: this is assuming that you're using EnergyPlus or one of it's interfaces.
