R32, R454B, R466A, and several other refrigerants are listed as candidates to replace R410A that is currently widely used in variable refrigerant flow (VRF) systems. However, it is likely to take some time before it is decided which of the candidate refrigerants will be the favorite in the future. In the current situation, R32 alone is used for certain VRFs and mini-VRFs in Europe.
