Daimler and Volkswagen reached an agreement over an air-conditioning refrigerant that Daimler claimed was flammable and extremely hazardous to one’s health.
Reuters reports that Daimler, together with Audi, BMW, Porsche and Volkswagen, will develop a “completely new A/C system that employs non-flammable carbon dioxide as an alternative to the new, flammable HFO-1234yf refrigerant.”
The current R134a used in virtually every A/C system will be banned in 2017, and HFO-1234yf had been tabled as the replacement substance. HFO-1234yf is said to be more climate friendly despite the numerous health risks claimed by Daimler, including risks of fire and toxic gases that occur during combustion. But its maker, Honeywell, claims that Daimler is just looking to save money by not using the more expensive HFO-1234yf.
The EU mandate to use HFO-1234yf is still on the books. Daimler R&D chief Thomas Weber told Reuters during the Geneva auto show that Daimler would be prepared to pay the EU compensation for violating the directive, although he stopped short of calling it a “fine.”
Today, Volkswagen announced
“its entry into CO2 technology, which will be rolled out progressively over its entire vehicle fleet.
Entry into CO2 technology will further contribute towards climate protection. CO2 (carbon dioxide) as a refrigerant – also known as R744 – is a naturally occurring gas with significantly lower greenhouse gas effects than conventional refrigerants, and it is ideal for use in specially designed automotive air conditioning systems. With a GWP (Global Warming Potential) value of 1, it is 99.3 per cent below the EU specified GWP limit of 150. “
