Daimler and Others “Press Ahead” with CO2 Mobile Air Conditioning

Reported by Reuters news agency (Mar 6)

German luxury carmaker Daimler AG and several of its German peers took an initial step towards resolving a safety scare over a new air conditioning refrigerant developed to meet an EU mandate.

Daimler said on Wednesday it had tasked its engineers with developing a completely new A/C system that employs non-flammable carbon dioxide as an alternative to the new, flammable HFO-1234yf refrigerant favoured my most of the car industry.

“We could agree in Geneva to press ahead with this sustainable and safe solution together with Audi, BMW, Porsche and Volkswagen,” Daimler research and development chief Thomas Weber said in a statement.

According to Daimler, the new HFO-1234yf poses a much greater fire hazard than many of its fellow carmakers currently believe.

The company’s critics, including the refrigerant’s producer Honeywell International Inc, argue there are many other flammable materials under the hood of a car and attack Daimler’s refusal to use the more expensive, climate-friendly HFO-1234yf as a thinly veiled attempt to save money.

Weber told Reuters during the Geneva auto show on Tuesday that Daimler would be prepared to pay the EU compensation for violating the directive, although he stopped short of calling it a “fine.”

The EU mandated that the existing R134a refrigerant be phased out beginning in January and it will be banned outright in 2017.

In order to meet strict new climate change targets set by Brussels, the auto industry agreed to use HFO-1234yf after tests in concluded in 2009 showed it was safe.

However, prompted by safety concerns from Germany’s Federal Environment Agency, Daimler carried out its own tests, which concluded there was no way its engineers could rule out the risk of a potential fire caused by the refrigerant, which also emits a highly toxic gas during combustion.

    so in other words,here in the 21st century,we can’t design a gas that imitates r-12 and is not explosive,and what about retro-fitting all those cars that have been retrofitted from 12 to 134a ,this has to be done again,seems one company is trading cash flow for another,and making millions on retrofit products,IMO
