Thermal comfort

With the EU F-Gas Regulation and the global Kigali Amendment to the Montreal Protocol, both introducing a phase-down of HFC refrigerants, reducing the climate impact of refrigerants has become an essential part of sustainable cooling. Development and use of refrigerants with a lower global warming potential (GWP) are a typical example of how this goal can be achieved, but should be complemented by a life cycle approach, investing into refrigerant recovery, recycling, reclaim and reuse of refrigerants. Such an approach will not only contribute to achieving the phase-down on a European and global level, but also to resource efficiency and to the Sustainable Development Goal (SDG) 12 on sustainable consumption and production.

• “Certified Reclaimed Refrigerant Allocation” with refrigerant recovery, reclaim (high quality recycling).
• Currently applied to Daikin VRV IV+ heat recovery, VRV IV S-series and Daikin Applied Chillers.
• An independent laboratory first assesses whether the reclaimed refrigerant is of the same quality as virgin refrigerant. A mix of new and reclaimed refrigerant is then used at the factory to charge the units.
• For the moment, the process is used for HFC refrigerants R-410A and R-134a, but the program has large potential to be expanded to other refrigerants in the future.

• By manufacturing with reclaimed refrigerants, recovered refrigerant is reused instead of being destroyed and production of new refrigerant is avoided
• In 2019, the first year of the launch of the “Certified Reclaimed Refrigerant Allocation” programme, the production of over 150,000 kg of new refrigerant was avoided.
