IIR Member news - Solstice N41 (R466A), a new refrigerant from Honeywell
Focus on a brand new refrigerant Solstice N41 (or R466A) which could represent an interesting alternative to R410A in air conditioning.
Alternatives to replace R404A for refrigerated transport
With about 5 million refrigerated vehicles operating worldwide, there is active research and development focusing on identifying alternatives to R404A, which is traditionally used in truck and trailer...
Air conditioning: which refrigerant will become the leading alternative to R410A?
R32 is being adopted widely for residential and small commercial air conditioning applications, but R466A, R452B and R454B are promising candidates, especially for larger size systems.
Latest news on HFCs alternatives
R470A, R470B, R466: What applications and what features for these new non-flammable refrigerants?
Alternative refrigerants to high-GWP HFCs
Intensification of international regulations on HFCs such as the Kigali Agreement or the European F-Gas Regulation leads refrigerant manufacturers to search for alternatives to high-GWP HFCs. Focus on some alternatives to R410A and R23.
Commercial refrigeration: marketing of R471A, a new alternative to R404A
Honeywell recently announced the marketing of R471A, a non-flammable refrigerant with a GWP under 150. It is expected to replace R404A in medium temperature commercial refrigeration...
IJR highlights: review of low-GWP alternative refrigerants
In a recent review article based on over 60 published studies and published in the International Journal of Refrigeration, Chinese researchers have compared nearly 40 alternative low-GWP refrigerants in terms of...
Air conditioning: towards a relaxation of the rules for the use of flammable refrigerants
While the European Commission is paving the way for the use of flammable refrigerants as an alternative for split systems, the current revision of the international standard IEC 60335-2-40 should allow higher...
Consequences of the EU F-Gas Regulation: uncertainty on the future availability of R404A
