Daikin opens free access to its patents on next-generation refrigerant R-32

Daikin, the worldā€™s leading manufacturer of air conditioners and refrigerants, has opened up free access to 93 of its patents to companies around the world. Daikin aims to promote the widespread use of the more environmentally friendly R-32 refrigerant difluoromethane .

The substance difluoromethane is non-ozone depleting, more energy efficient, affordable, easy to recycle and has a low global warming index GWP that is 1/3 of that of the currently most commonly used refrigerant R-410A. Daikin believes these benefits make R32 a new-generation environmentally friendly refrigerant whose widespread use will reduce the environmental impacts of residential and commercial air conditioning, refrigeration and heat pump systems.

The carbon savings from the worldwide switch to R-32 will be huge: if all current R-410A refrigerant is replaced with R-32, the proportion of these CO2 Could be reduced to 24% by 2030.

Daikin granted free access to patents to individual countries as early as 2011 to accelerate the phase-out of ozone depleting refrigerants such as R-22,ā€ said Shinya Okada, Daikinā€™s Senior Executive Director. ā€œGiven the urgent need to address climate change, Daikin believes that now is the right time to expand this access to manufacturers around the world.ā€.

In a move that will enable manufacturers to apply Daikinā€™s technology to their air conditioning, refrigeration and heat pump equipment, Daikin is urging the world industry to phase out R-22 refrigerant entirely and adopt R-32 to meet growing demand.

    Thatā€™s great news! Opening up access to patents can potentially lead to increased innovation and collaboration within the industry. However, Iā€™m curious about the motivation behind Daikinā€™s decision. Are they trying to promote the widespread adoption of R-32 or are there other factors at play? It would be interesting to understand their long-term goals and how this move might impact the future of refrigerant development.
