Refrigerants – Uncertainty regarding auto air conditioning
Two years ago, a new refrigerant, as the currently used is environmentally harmful. There are two new solutions already exist, but nobody knows which funds will be used now.
Some time ago, experts have recognized that the agent in car air-conditioning is environmentally harmful. So it was decided that another was needed – by the year 2011. What is in it as well – which refrigerant will continue to be found in air conditioning is not fixed yet.
Dessau / Berlin. Some time ago, experts have recognized that the agent in car air-conditioning is environmentally harmful. So it was decided that another was needed – by the year 2011.
An alternative was found quickly, even as manufacturers’ association VDA, the new solution was in order – it was said at any rate at the time in 2007. Now, however, is 2011 not far to drive but instead found the solution, everything changed. For now another alternative on the table. Although a new tool in a good year to be used, no one really knows now what will it be.
In the air-conditioning systems of cars, a refrigerant called R134a is used. This means, however, has a global warming potential that is 1,300 times as high as that of carbon dioxide (CO2). Each car comes with R134a, therefore, according to the Federal Environmental Agency (UBA) in Dessau from unavoidable leaks in the system per kilometer ride seven grams of CO2 addition. In Germany alone, 2006, about 2,300 tons came from R134a air conditioning systems of cars in the atmosphere.
European directive sets the tone
Experts was therefore long been clear that had to be made for replacement. And so it came to a European directive known as 2006/40/EC. It states that from 1 January 2011, only new passenger car models may be authorized to release their air conditioners a lot less unpleasant substances into the environment. In plain text may continue a certain amount of refrigerant in the plant more than 150 times its climate-damaging than the same amount of CO2.
The solution that was found was, at first somewhat surprising: CO2. For, while CO2 emissions in terms of the exhaust gases of a car as something is, the rate must be lowered, it has clear advantages in terms of air conditioning. What comes out of an air conditioning system in terms of environmental impact is called the global warming potential. The three letters are an abbreviation of “Global Warming Potential” and describe the risk of the product in terms of global warming: While R134a has a GWP of 1300, lies in the cold technically called CO2 R744 just at 1 Because of this, it seemed like the decision – and several producers commented on the development of appropriate car air conditioners.
Further refrigerant in an interview
Unexpectedly brought companies such as Honeywell then another refrigerant into the conversation. It is called HFO 1234yf from the perspective of manufacturers and has the advantage that it can also be used in the already existing air conditioning systems – however, needs new CO2 air conditioning systems.
There are at HFO 1234yf but also one major drawback: it is considered to be combustible, may, according to EPA to “make a fire highly corrosive hydrofluoric acid.” Although time is running until January 2011, is the bottom line but everything is open again. “The changes will come in 2011, but is still unclear which refrigerant will be used,” says Wolfgang Plehn of UBA.
The refusal decision could have consequences if it is actually far. The problem: “The industry should now already in its manufacturing facilities for the future air conditioning units,” said Gerd Lottsiepen, transport policy spokesman of the Transport Club Germany (VCD) in Berlin.
While the final decision still a ways off, for example, drops Honeywell stone unturned to make HFO-added 1234yf harmless. It is repeatedly referred to flammability of the composition, it is “10 000 times more likely that a person is struck by lightning than to be injured by a HFO 1234yf inflammation due to a crash.”
To Wolfgang Plehn it is unclear what such calculations are based on. The EPA is rather with the statement that the agent is flammable and that just may make the dangerous hydrofluoric acid. This in turn can lead to severe burns to skin and respiratory tract. “For the EPA, CO2 is an environmentally friendly alternative,” said Plehn. Which choice is the manufacturer make, must be seen.

The training concept with potential future CO2 bock practical workshops

Bock Training Centre in Frickenhausen
(Business Wire) Frickenhausen, 05.11.2010, with a novel training approach and the cooperation partners Danfoss and Knudsen Koling Bock offers hands-on workshops around the carbondioxid CO2 system engineering.

An environmental awareness has now spread across industries and in
numerous markets in importance. In many application fields of refrigeration and air conditioning to natural refrigerants and have prevailed among them in particular CO2.

For this reason, Bock has been providing mid-May 2010, with the cooperation partners Danfoss and Knudsen Koling Seminars, which can gather interested professionals theoretical knowledge and practical experience with CO2. The offer is aimed at plant engineers and planners.

Practical training on topics related to the compressor are since 2007 in its own stand-
Training center at the headquarters of the company offered. Around 1,000 people visit each year since to Frickenhausen there to enhance their mechanical and electrical engineering skills and compressor technology to practical experience.

The growing interest in the subject area of CO2 and the resulting demand for skilled technical personnel it was decided to buck, also offer special workshops covering all aspects of systems engineering include CO2. Because sometimes it is missing in most companies often of practical experience. The workshop was therefore a fully functional CO2 supermarket is built booster system equipped with the latest controls technology, refrigerated equipment for refrigeration and freezing and sub-and transcritical compressors.
Through the cooperation with Danfoss and Knudsen Koling flowed the experience of all three companies, not just in the new facility one, but is also reflected in the wide-ranging training content.

That CO2, especially in Europe’s most promising natural refrigerant and already often heard in use has its reasons. CO2 is not only environmentally sustainable as a refrigerant for supermarket systems. Also on security for the handling of the much higher system pressures, it is superior to many other solutions. Moreover, in Europe there are a relatively high number of skilled technical personnel and the moderate climate provides ideal conditions for CO2.
However, natural refrigerants are not only in Germany on the rise, they have attracted great interest among experts from all over the world. Likewise, natural refrigerants not only stood at the Mostra Convegno and this year Chillventa center stage, but were also the main topic at the Gustav Lorentzen Conference and the simultaneously held ARBS in Sydney, Australia.

Back in 2006, Bock presented the various compression solutions for stationary use of CO2 on the IKK and since then has steadily gain new experiences with CO2 systems and improve it. The partners Knudsen Koling and Danfoss look back on years of experience, the taxing to the success of CO2 training courses.

The focus of this training is the compressor, but just because the need for know-how in other areas is relatively high, all the important topics around the CO2 system technology.

The first courses have shown that the issue of CO2 is based on broad resonance and at the same time there is a great need for information. Especially in the handling of CO2 is still a large uncertainty felt by the practical “hands-on experience so important to make. Fact, the company during the first event, most of the questions the student on the handling of refrigerant CO2, differences to conventional refrigerants, installation and the components with higher pressure levels.

The conclusion of the bracket product manager for CO2 Manuel Fröschle is after the first successfully completing the training, therefore: can “To the participants of the training we see that just in terms of CO2, a high information need and we have followed the decision for the workshops in the right direction “.

Does anyone supply refrigerants for air conditioning? We would lkke to place articles on this here. Typical refrigerants of interest are: R-12, R-22, R-134a and R-410A
