R22 vs R410A Freon

We're moments away from signing the central air contract and I'm looking for your opinions on the freon....

our a/c contractor said that right now, r22 is more reliable. He said he's seen problems in commercial refrigeration units with r410A. he also said that r22 is ozone friendly and does not contain chlorine.

We know that after 2020 r22 will no longer be available but the life expectancy of the unit itself isn't more than 20 years.

Do you guys think we'll be ok with the r22 unit?

THANKS

I say go for the R22 for now it will be around till 2030.
Now R410a is good and all that. We do have to go to it. But for now the cost is to far out. First it is a mix of two freon's. Now say you have a leak in the unit and its over 50% of the freon in it. All the rest of the freon has to be taken out and all new R410a put in as a liquid. Thats so the mix is right so you see a leak in R410a can cost you a lot.

I agree with Ed. Nothing is wrong with R-410a but at the present time, it is expensive compared to R-22. R-22 will be around a long time but it will get more expensive and R-410a will likely come down in price as this refrigerant becomes the standard and becomes plentiful. What is driving this situation is government dictates because R-410a is supposed to be more environmentally friendly. Some of the manufacturers charge more for R-410a equipment. It is my understanding that the pressure in the condensing units has to be rated higher to handle this refrigerant. To answer your question, R-22 is OK at this point in time.

R-22 or R410A

Let me help y'all. R410A is the way to go as starting in 2010 the manufacturing of new units with R22 has to stop completely at the same time th elaw stats that R22 production has to be reduced by 60%. So what you are looking at is the cost of R22 going up 1000% just liek the old R-12.
So since your unit will be 6 yrs old in 2010 and if it has a leak we will find most a/c companies will convince people to replace them as the r-22 will be to costly.

Plus as of Jan 2006 the minumum seer will be 13 and most of those will all be R410A.

R-22 vs R-410a

I'm going to side with the R-22 guys. I feel strongly that even after the 60% reduction, there will still be plenty of R-22 around & yes it will be more expensive but I don't think it will skyrocket like R-12.
Just one correction on the original post: R-410a does not contain clorine, not R-22.

I thought neither one had it?!

My opinion is that this issue of R-22 vs R-410a is getting overthought and beat to death at this point in time. Both products are tried and proven and will do the job. It is difficult to forecast what the price of these refrigerants will be in 3,5,10,15 years. Both refrigerants will be available and frankly in year 2005, I think it is ridiculous to make a decision on equipment based on this single issue. One product has been proven to cause ozone depletion and the other is supposed to be ozone friendly. Having said this, I commend to your attention the following website for additional information.

http://www.410a.com/


What is ozone?
Ozone is a type of molecule that is made of 3 connected oxygen atoms, which is written in scientific terms as O3. It is mostly found in the stratosphere, and absorbs harmful ultraviolet radiation that would otherwise find itís way down to us and cause a variety of problems for humans, animals, and plants. Stratospheric ozone is different from ground-level ozone, which contributes to smog in our cities.

How could CFCs and HCFCs affect the ozone layer?
Ozone is constantly being made in our atmosphere, mostly by collisions of oxygen molecules (O2) and oxygen atoms (O). Ozone is also constantly being destroyed by similar collisions between O3 molecules and O atoms, resulting in pairs of O2 molecules. In theory then, there is a balance between creation and destruction that results in a constant layer of ozone.

The full names for CFCs and HCFCs are Chlorofluorocarbons and Hydrochlorofluorocarbons. CFC molecules are made of chlorine, fluorine, and carbon, and HCFC molecules also have hydrogen atoms attached. The widely accepted theory of ozone depletion is that these molecules, once emitted to the atmosphere, eventually are broken down over long periods of time into their individual atoms. The chlorine atoms then react with the ozone and cause ozone destruction to happen faster than ozone creation.

Why is ozone depletion considered bad?
Because stratospheric ozone protects us from harmful ultraviolet rays, ozone depletion means people, animals and plants are all affected by these rays when the ozone layer fails to stop them. This may include:

Increases in skin cancers.
Increases in cataracts of the eyes which can result in loss of sight.
Reduction in the yields of important food crops, according to some scientists.
Why canít R-410A affect the ozone layer?
R-410A is not a CFC or an HCFC. It is called an HFC, or hydrofluorocarbon, and is made of hydrogen, fluorine, and carbon atoms. Because it has no chlorine, it wonít interact with the ozone layer once it breaks down.

Now thats for the R 410a .Now lets look around here it looks like we are just after the chlorine thats in R 22 is all.So just how much of it comes from the AC units we have out there now that have like 3 lb of R22 in them and it gets out in the air. I think we should look at all the other uses that we use chlorine in . Just to start, the drinking water we have .All the swimming pools. Then when you wash clothes you put more chlorine in the water that will end up in the ozone later on. I cant think of all the other things that have chlorine added to them and washed with it. This all goes up to the ozone..
Now cost wise on freon R 410a. Oh boy its high now for sure. On top of that if you have a leak with the R410a and over half of the freon is out of it . Then the freon that is still in the unit has to be pumped out in a recovery set up. Then all new 410a has to be put in so its the right mix as 410a is two freons and you have to charge the units by liquid only.
Now we have tanks of used 410a no good. The freon companys wont take them back as they say they cant clean them and its not the right mix to be call 410a.
In all are we saving anything here at all. Might want to read this for sure.

Yeah Yeah Yeah and other countries will be producing R-12 R-22 R-410A and using it and venting it. so what now ?

Some thoughts think that global warming is HOG WASH!!!!!!!



Just my two cents worth.
