HFC action group slams new refrigerant
The HFC action group Beyond HFCs has hit out at General Motor’s decision to use the new Honeywell/DuPont manufactured refrigerant HFC1234yf in vehicle AC systems.
In a statement it claims that independent tests have found the HFC to be flammable at low concentrations in air and of risk to humans if vented into a vehicle compartment, such as in a traffic accident.
It also asserts that when 1234yf is vented into the atmosphere it decomposes into trifluroaceticacid, which, when leached out by the rain develops a herbicide effect.
Furthermore, its voiced concerns over DuPont and Honeywell’s holding of the patents in all major markets, which, it states, “gives them the power to dictate price and makes car manufacturers totally dependent on them.”
