Automotive Refrigerants

An automotive coolant Daimler claims is too dangerous to use in their vehicles, despite the warnings from the European Union to cease usage of an older coolant considered harmful to the environment, was found to be safe according to a report made by EU scientists.

Reuters reports the coolant in question, the Honeywell and DuPont co-developed R1234yf, posed “no evidence of a serious risk in the use of [the] refrigerant in mobile air-conditioning systems under normal and foreseeable conditions of use” as reported by the Joint Research Council in their findings last week.

Daimler, who claimed the coolant emits a toxic gas when burned, defended their position against using R1234yf, claiming the research “too restrictive,” preferring an option to develop a system using carbon dioxide as the cooling method, though said system is years in the making.

Meanwhile, the automaker uses R134a, an older coolant that the European Commission has found to have a global warming potential 1,000 times that of carbon dioxide while developing an air-conditioning system; EU rules state new coolants must have no more than 150 times said potential. As a result, the Commission has begun legal proceedings against Germany over Daimler’s current action on the matter.

R1234yf is currently 500,000 cars according to Honeywell, who expects the coolant will be in more than 2 million units by the end of 2014.

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.”

Update:

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. “
