Global Warming on trial...

Yeah, when they first came out with R-134, the systems were not that good and people hated them. they finally figured out that you needed 1/3 more condensor capacity than an R-12 system and got the pressures into managable zones, then the systems we have today work well. My 2004 Dodge truck will run you out in 118* heat if your buzzing down the freeway, you actually have to turn the temps up or freeze your buns off. I'd like to remind everyone that lives in cold winter climates to run your AC at least a couple of times a month to lubricate the seals, makes them last a while longer.

The majority of scientists who don't work for corporations would be out of research money if global warming didn't exist.

I think if you laid all the scientists in the world, end to end, you wouldn't reach a conclusion.

No kidding. This idea of consensus is complete bullshit. All it takes is one scientist who can document and reproduce evidence to the contrary to call everything into question. That is how science works. I was reading an article yesterday, and the guy hit it dead on. If people tell you to accept a theory based on 'scientific consensus', steer clear, it's not motivated by science.

So you've just agreed that Global warming does exist, Well that's so nice Just-in, Now when you've figured out Man has had a major hand in it, let me know~LOL~.
They didn't just finally figure it out, the reason R-12 was used was its high capacity for heat absorption and release during the phase changes, R-134 has less heat absorption capacity so therefore more R-134 must be moved to carry the same amount of heat. With a system designed for R-12 then using R-134 in it the whole system is undersized and the compresser trys to compensate. But to compensate it needs to lower the evaporater pressure and raise the condensor pressure to equal the movement of heat with R-12, So understand that all parts of a R-12 system is undersized for R-134 and increasing the size of the condencer, evaperator and/or the airflow across one or both will cut the work of the compresser [which is undersized for R-134 within the limits of the R-12 system. A thermastatic expansion valve will self compensate but the compressor, condensor and evaporater are just undersized. Increasing compressor size will increase heat&pressure differentials and do the job, but it not only increases the risk of leaks it also will cost you extra every time you use it. The evaporater is a bit locked in size wise and though fan speed could be in creased, this area is already close to maxed out, So this leaves the condensor its easier to get to and theres room to expand. Simple.
Very true, Just run your AC a couple times a month no matter where you live, there is oil within the system. Also if you move a refrigerator and lay it down you can move the oil where it can get into the compressor and oil doesn't compress and could break your compressor so if you do this make sure it is turned off and then plug it in for a few hours before you turn it on.medicineman393979 said:

Just pointing out that everyone has a motivating factor behind what they're saying, its up to us to research both sides of the argument to form an educated opinion; something you have obviously not done.

Just as I said, they increased the size of the condensor as that was the cheapest fix. I also stand by my claim that in the changeover years, I believe in the early 90s, the first couple of years, they had some problems keeping up with the desert heat. The actual size of compressors (in automobiles) has decreased in size over the years as they have been made more efficient. Not being an engineer, I can't quote you formulas and dimensions, but having something sorely lacking in todays society (common sense), I can see something for what it is.

Yes, but med not understanding the whys and wherefores, may leave you able to make something work but not understanding why it works, and this is your short coming.
Common sense is the least common of all the senses.

Politicians are wiley motherfuckers. They just invent shit to make millions and millions of dollars. The Republicans have the war on terror and the Democrats have global warming.

I agree on blaming the electorate, but the majority of the electorate, It seems, are very mindwashed and only watch TV and Eat junk food, a perfect combo for disaster. How in the hell do we change that. Getting government out of the schoolbook business, (McGraw-Hill) may be a start. I'm pretty sure there are a lot of made up stories in those history books. The Viet-Nam war was 2 paragraphs in my sons history book in the 80s, the gist of it was: "An unpopular war fought in Southeast Asia where 56,000 US troops lost their lives". And that was all. I wonder what the Iraq war will look like?

We're making progress with ya, Med. Now if only we can move you off of the "free" medical dime.
And, you are dead on about the history books. Ronald Reagan gets one paragraph and Che' Rivera and Ceasar Chavez gets a whole chapter.

You see, Vi, It's not free, It's just for everyone, everyone will be covered. We'll have to pay with higher taxes and rich guys like you can keep your expensive Dr.s. The lack of co-pays, Insurance Premiuns etc. will offset the costs. We need to take profit out of medical, pay doctors well and cover every citizen. The amount of money spent on medical per person in America is well above the world average and 50+ million have no coverage at all. The salaries of Insurance and HMO CEOs are outrageous. No one is worth that much money, and how do they earn it, by cutting medical procedures to the bone. Making life and death decisions about other peoples health, Butchers all.We're making progress with ya, Med. Now if only we can move you off of the "free" medical dime.

I see VI has no reply to my above thread, why? Because he knows it to be the truth!!!
The prophecies spoken of in the revelations of saint john do appear to be coming true according to allot of people. But before you go planning on what your gonna wear during the rapture theres something you may want to remember. Saint john wrote revelations about 79 years or so after christ death. the part of the rapture was added by a pope about 700 years later. i was raised southern baptist and growing up the idea that all gods children would be magically swept away before the world went to shit sounded like a great plan, how ever based on what i know now about the catholic church and more so about how they have historically changed their views and what they teach to sute the views of the masses leaves me to wounder. I'm sure the world will end one day, probably sooner then we all think, but i'm not so sure that all of us wont be here to have a frount row view of our own ignorance coming back to bite us in the ass.

I didn't answer it because you and I have pounded this one into the ground. I'm beginning to think that we should just agree to disagree on this issue.

My points to you two sweathearts (Vi and Medicine) is that we have two huge problems in health care. The currancy is is inflated and almost meaningles. A dolllar won't even buy a small bottle of asperin anymore. Doctors must have huge bills to cover their cost like malpractice and student loans. The second problem is the strangely disproportional costs of procedures based on location. OK class, let's all say supply and demand.
The medical costs need to be leveled in several respects.
