 | Honeywell has announced that its Solstice N41 (R466A) refrigerant has received the official designation A1 by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), making it the first A1 non-flammable low GWP alternative to R410A. Available from next year, Honeywell says its scientists devoted years of research and development to solve a key problem facing the industry. |
George Koutsaftes, president, Honeywell Advanced Materials, said: “We developed Solstice N41 to address the many regulatory and safety challenges facing the industry. This product is the first non-flammable refrigerant developed as an R410A alternative, and is also better for the environment, energy efficient, and cost-effective for the end user with minimal conversion required. Safety is paramount and the properties of Solstice N41 make it a groundbreaking technology for the industry.”
Regulations including Europe’s F-Gas regulation require the phase down of high GWP products, prompting the HVAC industry to seek new alternatives. The current industry standard refrigerant, R410A, which was developed and brought to market by Honeywell, must be replaced with an energy-efficient, lower-GWP solution with similar or better performance.
With a GWP of 733, 65% lower than R410A, Honeywell says Solstice N41 is the first replacement refrigerant that delivers all three attributes. All other R410A replacements alternatives proposed to date are flammable and require changes to equipment safety standards and building codes.
Honeywell adds that early testing indicates that Solstice N41 requires minimal changes to equipment and no additional training for installation and repair technicians, allowing original equipment manufacturers to convert from R410A. In addition, there is no additional safety or liability risk to homeowners and the whole supply chain.
Solstice N41 is being tested by over 15 OEMs and leading compressor manufacturers, having accumulated more than 30,000 hours of testing in different applications such as commercial AC (VRF, rooftops) and residential systems.
Honeywell previously confirmed that it was working with manufacturers including Toshiba Carrier, Midea and Sanhua.
