Anyone reading up on the new refrigerant

that is coming?

This is out of an article from autocarepro. Here we go.

Quote:
HFC-134a has a market price of about $12 to $18/kg when sold in small 500-gram cans typically purchased by DIYers. HFC-1234yf has an expected chemical production cost of $40 to $50/kg, which would be $60 to $90 per small 500-gram can at the current markup

Stupid. Automakers should move to R-744 (aka CO2) with a high-pressure sealed electric compressor. Basically non-toxic, CHEAP to replenish.

Sounds more than reasonable to me.

Sounds good to me, anyone seen one of these set-ups on a car?

Any special power/other requirements or limitations?

Good point Click. It might embarass him for me to do so.

I've known Jim via the forum for about 10 or 12 years and even spoke to him on the phone a long time ago.

If he would rather I not call him by his first name, I understand and will honor his request not to do so.

Article in the NYT this week about the increase in air conditioning in Asia and the adverse effect on the environment of the gases. It pointed out that Europeans use propane in their refrigerators (it called the gas a hydrocarbon--not propane) and suggested that it would be good to use hydrocarbons in auto AC.

It would be good to use hydrocarbon refrigerants. They are cheaper and perform better. Unfortunately Dupont has the market cornered and hydrocarbon refrigerants dont have a prayer.

While buying some parts at the local GM dealer a few days ago I was talking to the counter guy who said that GM was going to this soon, he had heard in 2013 cars but maybe it would be phased in like R-134 was over a few months.

He quoted some figures that he said might not be accurate, but were close. R-12 will break down, when released, in something like 500 days. R-134 takes about 160 days. The new stuff breaks down in the atmosphere in 11 days.

I do recall when R-134 came out there was a big cry about using Propane but the DOT refused to allow it since it created a fire hazard in an accident. Of course the automotive press pointed out that gasoline never presents a fire hazard in a accident, but the DOT did not see the humor.

Well the DOT has common sense at least occasionally.
