refrigerant for use in stationary air conditioning systems.
Once on the market, Solstice N41 is set to be the l owest GWP, nonfl ammable, R410A replacement refrigerant available worldwide. The refrigerant received a provisional number and a preliminary A1 designation from the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), a key requirement for bringing the p roduct to market.
The innovation comes after years of research and development by Honeywell scientists who set out to address one of the most vexing regulatory a nd safety challenges facing the HVAC industry. A ll other alternatives proposed to date as R410A r eplacements are fl ammable and require changes to safety standards and building codes.

g eneral manager of Fluorine Products, said: “What w e have invented and developed in Solstice N41 i s a remarkable breakthrough. It is an incredibly promising product that is poised to solve a key problem and potentially become the next big global advance for refrigerants.”
W ith numerous regulations – including Europe’s F -Gas regulation and the internationally adopted K igali Amendment to the Montreal Protocol – requiring the phase-down of high global warming products, the HVAC industry has been looking to replace the current industry standard refrigerant, fficient, non- fl ammable,

Mr Rastogi continued: “Solstice N41 off off ffers a unique combination of benefi ts. With a GWP that

ersion to a fl flammable refrigerant.
In addition, early testing indicates that switching t o Solstice N41 would require minimal changes to equipment and no additional training for
installation and repair technicians. Preliminary data indicates that the refrigerant may allow OEMs to easily convert from R410A.
ASHRAE has determined that Solstice N41 has an A 1 designation, the same as R410A.
Solstice N41 joins the family of Solstice products which Honeywell developed to accelerate the transition from away from materials with high GWPs.
It is expected to be available commercially in 2019.
