Has anyone been successful obtaining and using manufacturer compressor curves for transcritical CO2 refrigeration systems? I have attempted to download the transcritical/subcritical compressor curves from manufacturer and apply in model; however, the energy use is all over the place (extremely negative OR extremely positive).

EnergyPlus doesn't follow the ARI Standard 540 exactly and requires the user to tweak the order of the coefficients for compressor performance curves. Also make sure your coefficients are in the right units where applicable.
