HFO1234 to challenge CO2

Honeywell touts refrigerant used in cars as ideal for commercial retail

The new synthetic refrigerant HFO1234, is expected to challenge carbon dioxide in areas ranging from beverage cooling to commercial refrigeration, according to refrigerant producer Honeywell.

Product specialist Nacer Achaichia told the RAC Alternative Cooling Conference that two molecules of the gas, yf and ze have shown good performance characteristics, particularly a very short atmospheric lifetime.

He said: “We believe these molecules will have an important role as a beverage cooler, but there is high potential in areas such as small commercial refrigeration and centrifugal compressor applications, as pure molecules and as blends. They are easily manageable and, unlike CO2, do not require significant hardware modifications.”

He said that HFO1234yf and ze  had GWPs of 4 and 6 respectively, but their lifetime of 11 days and 18 days was significantly better than other gases.

“For 134a it is 14 years, while for CO2 it is probably generations,” he added.
