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: 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.
New R134a alternatives in mobile air conditioning
Two new refrigerant blends are considered as an R134a alternative and "virtually non-flammable".
The US Environmental Protection Agency (EPA) updates its list of low GWP refrigerants
The US EPA has added new lower GWP refrigerants and expanded the acceptable uses of others in its latest changes to the Significant New Alternatives Policy (SNAP) programme.
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...
