Recently multinational HVAC equipmentmanufacturer Daikin announced it will be offering other equipment manufacturers free access to some 93 of its patents in order to promote global use of the environmentally-friendly refrigerant R32.
This, of course, is in answer to coming international phase-outs of the HFC refrigerants. Those phase-outs are in response to the phase-outs of HCFCs deemed unfriendly to the earth’s protective ozone player. And many of those phase-outs were in response to the phase-outs of CFCs, which probably actually were unfriendly to the ozone layer, but not in quantities used by the HVACR industry. Yes, it’s becoming that silly.
