Re: Freeze-12, alternative R-12 refrigerant

Interesting side note about the ozone layer!

There was a hole discovered in the ozone layer over the north Pole and South Pole. This was going to… some day... cause the solar cap to melt and flood the world’s beaches and God only knows how much more.

The cause was determined to be the use of Freon 12.(r-12)

Solution was to let the government start controlling the situation… you know, the people in our country that have as a group never done anything and actually know nothing about anything.

The same geniuses had a few short years earlier condemned us all to death by freezing. Yes, the new ICE age was on the way. Something to do with our love affair with driving our cars.

Older folks here will probably remember the ice age returning thing, depending on how old and how much memory is left.

I heard on the news this week that when us people bring up the ice age scare, that we are lieing. Of course we aren’t.

Although the earth has actually cooled a degree during the last 6 years they still tell us we are on the way to destruction from "earth warming". I think they must have read the tee leaves and decided to change the name to "Climate Change" That way with any change in any direction they can claim victory!

Back the ozone layer… The government… affectionately referred to as the “Gestapo” made it so we couldn’t buy R-12. They did it in 2 ways.

1. They made it a crime to buy or sell r-12 to us without getting a special license and spending thousands of dollars worth of extra equipment.
2. Jacked up the price. 30 lbs was $20.00 retail at discount stores… It went to $1,600.00 wholesale if it could be purchased.

Latest information on the Ozone layer is…

Since the F-12 fiasco, the icecap IS melting at the North Pole.
The ice cap is NOT melting at the South Pole.

The Ozone hole has filled in at one of them, but not the other.

Which one????

The North Pole no longer has the hole in the Ozone layer and the ice cap IS melting.

The South Pole still has the hole in the Ozone layer and the ice cap IS NOT melting.

Yes, the inmates are still running the asylum.

I am back here reading the rest of your post. I am sorry, I had to get up and get a coat. I hate to admit this, but I remember about the ice age that was going to freeze us all.

Keith, this probably deserves a topic of its own! Got a great laugh from that, thank you!

Now would definitely seem to be the winter of your discontent, as Shakespeare might have put it!

Weather systems and climatology have got to be the least satisfactory scientific fields of study especially from the point of view of cause and effect. The short term systems exhibit chaotic behaviour on a grand scale so that after two centuries of dedicated study we can now "predict" weather patterns locally, but only for the next 2-3 days with any reliability.

Long term climate cycles do not have recorded or reliable data going back a long enough period, so a lot of the deductions here are guesstimates, with experts differing sharply on causes and on the severity of effects. And that's not even taking DuPont's patent problems into the PR arena!

You could probably take all these predictions with a pinch of salt. Although salt is bad for your heart.

Or is it your blood pressure? Or cholesterol?

I forget.

Joe

Think that would be blood pressure, Joe.

Cholesterol has it's own interesting dilemma! Of course, there is good and bad Cholesterol.

The claim is that high Cholesterol can cause a heart attack.

Fact... The same argument can be made that not having high Cholesterol causes heart attacks.

Why? Because half the people that have a heart attack do not have high Cholesterol. Which is it really?

Half the people that have a their first heart attack will assume room temperature that day. Half of those dead folks did not have high Cholesterol. Is living without high Cholesterol just as dangerous.

Again, the inmates are running the asylum.

Keith

On the salt thingie, I would suggest switching to "sea salt" just to be safe.

Some of us will be closer to the source, soon as we get the promised rise in the level of the oceans!

Re: Freeze-12, alternative R-12 refrigerant

Aye, the inmates are wearing the badges all right.

Thanks for the advice, I was joking a little about the salt, as you know. I'm constantly amused by the fact that every five years or so something we were previously warned against that could kill us is likely to have a turnaround and be found as beneficial.

My wife takes the view that we should eat a varied diet and eat anything we like, but in moderation. I concur with her opinion, although we differ on small things like the correct level of beer or wine or chicken legs.

We have been using sea salt for years, would not use anything else.

Joe

Same here and leaning toward organic everything where ever possible. The chemical fertilizers and chemicals in the home are a killer.

Take a look at one of my web sites and change your life!

How far off topic can I go before I am banned from the form?

Install new receiver/dryer (gets rid of some of the old oil and you can't flush it out) and o-rings, mount compressor and fill with PAG oil (2.5 oz). NOTE: the general source of leaks is the compressor seal. It's the shaft seal between the compressor and the clutch. The compressor runs almost constantly and the seal will wear out. Don't fix this and the work done is pretty useless. Evacuate the air out of the system to remove all the water vapor. Don't do this and the water vapor will freeze at the expansion valve and plug the system. No freon flow = no cooling.

There is a pressure switch in the system so you will need to start pressurizing the system for the compressor to start. Pressurize thru the low pressure side. That's the line from the firewall to the compressor. Charge with 24oz of referigerant (two cans) and enjoy.

If you live down south, you are going to need window tint. The film in the windshield helps but the side and back glass just will bake you without it. The A/C system has to not only cool you but to reduce the temperature of the vehicle interior for you to feel cool as well.
I am considering doing this, one thing I would like to know is, does anyone have a diagram of svx a/c system showing receiver/dryer and expansion vale locations?? Also how cna you flush the system if you dont have an air compressor?? Did you change the shaft seal tooo?? if so, where did you get the seal for our compressor? I changed it on Alfa Sanden compressor.

thanks,
-Pavan.

Re: Freeze-12, alternative R-12 refrigerant

You can't replace anything on the compressor because Subaru doesn't sell individual parts. Maybe an hvac repair shop maybe able to do this.

Yes, no car company provides those individual parts for compressor (AFAIK), because they all are from other companies like the most popular Sanden compressors. And you can source them from Harold Electric Co. for most of the compressor models. I would like to know if he did indeed replace it since he mentioned it in his post.

Yeah it is, and I've heard of people using it in AC systems although it's illegal and I do not recommend it. The big diesel fired reefer units that they use to cool semi trailers and such actually use propane as a refrigerant, since they are usually mounted to the front of the trailer, there is little danger of them getting punctured in an accident.

I've often thought of getting ahold of one and running it on biodiesel, would make a pretty spiffy, albeit noisy, shop cooler!
