5 VRF Refrigerant Trends

As candidate refrigerants for variable refrigerant flow (VRF) systems, attention has been focused on refrigerants with low-global warming potential (GWP) values such as R32, R454B, and R466A until now. During the period spanning the latter half of 2023 to the beginning of 2024, trends in next-generation refrigerants for VRFs were rapidly becoming clear.
