Multi-pack centralized refrigeration systems for commercial use with a nominal capacity of 40 kW or more that contain or require for their operation fluorinated greenhouse gases with a GWP of 150 or more, except in the primary refrigerant circuit in cascade systems where fluorinated greenhouse gases with a GWP of less than 1 500 may be used.

In addition, an explanation of what exactly is meant by centralized refrigeration systems for commercial use.
