In my opinion, it will increase as described some posts higher of me.
This is where the explanation gets confusing.

If subcooling is available and used to overcome the pressure losses (horizontal or vertical piping) then the subcooling does not increase the compressor capacity. The subcooling is being used to keep the refrigerant in the liquid line at 100% liquid. If you get flash gas in the liquid line then the compressor capacity (cooling capability) will decrease.

If the subcooling available is greater than the above, then the additional subcooling helps to increase the compressor cooling capability. This is due to the greater enthalpy difference available with the remaining subcooling.
