 | Honeywell is working with Chinese controls and components manufacturer Sanhua to commercialise the use of its Solstice N41 (R466A) non-flammable lower GWP refrigerant in new and exisiting air conditioning equipment. Due to be launched later this year, R466A is designed to replace R410A in stationary systems and has been heralded by Honeywell as a 'remarkable breakthrough'. |
Chris LaPietra, vice president and general manager at Honeywell Stationary Refrigerants, said: “We specifically designed Solstice N41 to solve industry challenges and comply with regulations; this will be a revolutionary solution once it is ready for adoption later this year. This partnership with Sanhua reaffirms our commitment to delivering a safe, energy efficient and environmentally sustainable alternative to R410A.”
Once commercially available, Solstice N41 will be the first A1 non-flammable, lower GWP R410A replacement offered for stationary air conditioning systems. Solstice N41 also offers a GWP that is 65% lower than R-410A.
Huang Ningjie, vice president and chief scientist of Sanhua Holding Group, said: “The non-flammability attributes of Solstice N41 make it a game-changer for the HVAC industry. We have achieved significant progress on qualifications of HVAC critical components for use in air conditioner refrigerants using Solstice N41, and the assessment is expected to be completed within this year. We’re well positioned to serve the industry as it prepares to transition to Solstice N41 later this year.”
N41 significantly reduces the need for additional design and eliminates the need to incorporate any sensors typically required for minimising flammability risk. Honeywell says that early results also indicate that it will eliminate the need for specialised contractor training for flammability.
Earlier this year, Toshiba Carrier recognised Solstice N41’s potential as a R410A replacement to meet requirements under the Kigali Amendment in Japan. In June it was announced that air conditioning equipment manufacturer Midea Group was looking to use Solstice N41 in all its VRF and chiller systems.
