Honeywell Partners With DunAn Environment To Advance Solstice® N41 Refrigerant

MORRIS PLAINS, N.J., November 23, 2021 -- Honeywell today announced Zhejiang DunAn Artificial Environment Co., Ltd (DunAn Environment), a leading global manufacturer of refrigeration equipment and components, will assist in driving the HVAC industry transition to Solstice® N41 (R-466A) by developing their product line of HVAC components as compatible.

Solstice N41 is the industry’s first A1, non-flammable lower-global-warming-potential (GWP) refrigerant replacement for R-410A in stationary air conditioning systems, and reduces global warming impact by 65 percent.

Multiple worldwide regulations require the phasedown of hydrofluorocarbon (HFC) solutions under the Kigali Amendment to the Montreal Protocol. With regulations under Kigali officially taking effect in China in September and China’s aim to achieve carbon neutrality by 2060, HVAC component manufacturers are increasingly seeking alternative low-GWP solutions.

“The non-flammability and reduced-GWP properties of Solstice N41 provide real breakthroughs for the HVAC industry," said Shan Yukuan, deputy director of Technology Center, DunAn Environment. "DunAn is glad to partner with Honeywell to carry out evaluation and certification of key HVAC components for Solstice N41 use and promote the widespread application of this innovative technology. We believe this partnership with Honeywell will provide safer, more energy efficient, and more sustainable products for the HVAC industry.”

Solstice N41 provides the same level of safety to contractors and customers as R-410A. Other alternatives proposed as R-410A replacements may be higher risk due to their 2L (low flammability) rating, which may require changes to safety standards and building codes and OEM equipment production lines.

To date, Solstice N41 has undergone extensive analysis by over 15 original equipment manufacturers (OEMs) and leading compressor manufacturers. The product has accumulated more than 100,000 reliable hours in different applications like commercial air conditioning (variable refrigerant flow, rooftops) and residential air conditioning (unitary ducted equipment in the U.S.).

"Solstice N41 is a revolutionary, sustainable solution for the HVAC industry. It was specifically designed to address industry challenges and meet regulatory requirements thanks to its safety, energy efficiency, and  reduced global warming potential," said Ken West, vice president and general manager, Honeywell Fluorine Products. “By working with leading air conditioning and refrigeration manufacturers and component suppliers such as DunAn, we can move towards industry adoption and help customers meet overall sustainability goals.”

DunAn Environment is a leading enterprise in the global refrigeration components industry, and a strategic partner for global air conditioning manufacturers. DunAn components manufacturing includes refrigeration valves, heat exchangers, and pressure vessels for household and commercial air conditioners, heat pumps and refrigeration and freezing. In addition, DunAn provides components for thermal management of new energy vehicles and equipment manufacturing, including commercial air conditioners, special air conditioners and cold chain equipment for nuclear power, purification and rail transit.

Honeywell is a world leader in the development, manufacture and supply of refrigerants that are sold worldwide under the Solstice^® and Genetron^® brand names for a range of applications, including refrigeration and building and automobile air conditioning. Honeywell and its suppliers have completed a  billion dollar investment program in research and development and new capacity based on Honeywell’s hydrofluorolefin technology. Worldwide adoption of Solstice products has avoided potential release of more than 250 million metric tons of carbon dioxide into the atmosphere, equal to eliminating the potential emissions from more than 52 million cars per year.

Honeywell recently committed to achieve carbon neutrality in its operations and facilities by 2035. This commitment builds on the company’s track record of sharply reducing the greenhouse gas intensity of its operations and facilities as well as its decades-long history of innovation to help its customers meet their environmental and social goals. About half of Honeywell’s new product introduction research and development investment is directed toward products that improve environmental and social outcomes for customers.
