R-134 Global warming, massive leaks?
Hi, I am new here.. Nice forum!
http // :
environment.newscientist.com/channel/earth/climate-change/mg19125712.700"...... of Ny-Alesund, part of Norway, is a watchtower of climate change. Instruments on its summit consistently detect the world's highest concentrations of atmospheric carbon dioxide. Now it is recording an alarming surge in a far more powerful greenhouse gas, called HFC134a. Just one molecule has a warming effect more than a thousand times that of a molecule of CO2..."Is there, today, any automobile A/C originaly charged with R600?
"...The Norwegian Institute for Air Research says concentrations of the gas above Mount Zeppelin doubled between 2001 and 2004. "This gas has a warming effect on the planet more than a thousand times that of CO2"
Manufacturers of air ...."

Hi Propane and welcome to the forum.
As far as I know there aren't any production vehicles with R600 in there a/c system, they're still running R134a.
With regard to the R134a increase be aware, as MG said, that it is/was a gas used as a propellent in quite a lot of aerosols so don't lay the blame on car a/c alone.Brian - Newton Abbot, Devon, UK

Petrol, Oil, Airbag gas cannsiters and you want another explosive in a car
I Think R134 is here to stay in the car market, Crazy thing though, the most easily leakable and hard to trace gas in an a/c system in the most awkward places to find a leak and work on
so glad i dont have to work on cars anymore

Re: R-134 Global warming, massive leaks?
as already pointed out, 134a is still widely used as a propellent,most notably in asthma inhalers. maybe a link could be made between rising asthma suferers and the rise in 134a in the atmosphere? xxx

Re: R-134 Global warming, massive leaks?
They have now started to phase out the use of refrigerent as a propellant in asthma inhalers. Someone in the green brigade thought it was a good idea. The fact you probably vent 10 times the amount an inhalers when you purge or remove a line doesnt count.
If you have an asthma attach you now have to take you inhaler into the van and use it with youre R134a
Yes, I do have Asthma before someone says im a heartless git

PS Could CO2 be used in the auto industry, has it even been tried. Seems the safest option but does it have the capacity on a small scale ?Last edited by Latte; 02-02-2007 at 08:50 PM. Reason: Its Friday Night and ive lost the ability to spell !!!

Re: R-134 Global warming, massive leaks?
There is a video clip of a guy in New Zealand who deliberetly vents about 120 grammes of R600 into the foot-well of a car and tries to ignite it.
The first two test runs are fine with no ignition of the flamable vapour.
Then on the third test the whole lot goes up in flames and the guy who ignited the gas is left staggering around smoking.
The instigator was prosicuted on health and safety grounds.

Re: R-134 Global warming, massive leaks?
A couple of months ago came across foam rectangles cut with 12 circles in the public rubbish bins.. useful for padding microphones so searched a bit more...found "medical grade" R134a in welding torch size cannisters: apparently used to cool the laser gun at the beauty clinic next door - mentioned it to a friend from UK (ex-service manager) he went loopy: apparently it is an offense to vent such a gas in the UK, so what about the rest of Europe?
Infuriating that we fridgies get the blame for everything or can we be blamed that we like our ladies with no hairy legs
