Bad marks for air conditioning systems

Stuttgart – Worldwide, 600 million cars have air conditioning. And there are constantly more. By the year 2015, about a billion air-conditioned vehicles are the way to estimate the IPCC. Environmentalists accuse the industry to rely on outdated air-conditioning and refrigeration products and dangerous so to enhance the greenhouse effect. “Pro Air – Efficient Car air conditioning systems with natural refrigerants” – is the name of a new Europe-wide information campaign that started the German Environmental Aid Association and the Transport Club Germany.

Debate on the energy concept, the right way “to municipal utilities
show all items “The operation is funded by the EU Commission. The main objective is to educate consumers, particularly motorists on the environmental impact of facilities and enforce better air conditioning technology. Environmentalists have been fighting for years for more efficient equipment. DUH VCD and complain that the car industry to undermine the EU’s climate change law and endangering motorists with new toxic refrigerants. Using sleight of “trying the industry, the EU ban of harmful refrigerant R134a (tetrafluoroethane) to circumvent, this is true in 2011, the DUH-CEO Juergen Resch criticized yesterday in Berlin.

Environmentalists have asked the auto industry. Thus, according to Resch’s current intention is not a single manufacturer, and from next year to give new models to R134a. Instead, models were already logged for the next few years with the technology now allowed. The refrigerant 134a once replaced the dangerous and jointly responsible for the ozone layer is chlorofluorocarbons (CFCs), heat the atmosphere but after DUH details 1430-times stronger than carbon dioxide (CO2). Of the leakage, accidents and improper scrapped in 2006 alone, according to EPA about 2,300 tons of R134a came into the open. This is consistent with the extremely high output of three million tonnes of CO2 and thus the climate impact of 1.7 million small cars to drive the 15 000 kilometers, expected before the environmentalists.

The industry makes a bicycle kick

Resch is especially the President of the Association of the Automotive Industry (VDA), Matthias Wissmann, disappointed. Wissmann had promised after taking office, the replacement of the existing air conditioning technology, criticized Resch. Accordingly, should air conditioning systems in new vehicles will be working with the natural, unproblematic refrigerant CO2 produced in large quantities as waste material as in energy production in power plants. This promise was “broken, like many other climate change and fuel excise promise” the auto industry but.

The stated reason for rejection of the interim CO2 Technology suspect environmentalists higher conversion costs for the automakers and the influence of the chemical industry. Manufacturers like BMW, which had forged ahead in CO2 air conditioning systems, made according to Resch backed down, because each vehicle would be created initially costs of about € 50. For the CO2-pressure compressors and other equipment more lines are needed. In addition, the chemical industry to penetrate an artificial substitute for R134a, which have brought the industry billions in sales. The substitute 1234yf, patented the left and the two chemical giants would use the automotive industry continue to cool it, there is less harmful to the climate, but expensive and in case of fire are highly toxic to criticize VCD and DUH. “We go from bad to worse,” complains Resch.

Environmentalists complain also that a great many cars are traveling with outdated, non-controlled air conditioning. Their fuel consumption was up to 2.5 times as high as in modern systems. But the replacement of the old plant could relieve the world’s climate 40 million tonnes of CO2 per year. The auto industry has rejected the criticisms of environmentalists. The new refrigerant 1234yf was safe, the use of safe, a spokesman said on request. Therefore we have chosen. You also need a “global standard and not an island solution”, said the association
