HFO1123 – a new alternative to R410A?

JAPAN: Asahi Glass, a Japanese refrigerant manufacturer supplying Honeywell with R1234yf, has announced that it has developed a new refrigerant for use in air conditioning systems.

Carrying the brand name Amolea, it is described as a blend with a new hydrofluoro-olefin, HFO1123, as its main component. The manufacturer gives no details of the characteristics of HFO 1123, nor does it reveal what the other components are. Neither does Asahi Glass give any indication of the refrigerant’s flammability, although one might assume it to have an A2L classification in line with other HFOs.

Amolea is being promoted as a replacement for R410A and a competitor to R32, the low GWP single component refrigerant being pursued by most Japanese air conditioning manufacturers. Amolea is said to have a GWP of around half that of R32, suggesting a GWP of around 350.

It is said to provide equivalent performance to R410A which would suggest it is not as efficient as R32.

Commercial production will start in 2016.
