Timeline for Phase out of R22 Refrigerant
Bright Hub Engineering ^ | • updated: 1/20/2010 | Haresh Khemani

Posted on 06/11/2017 5:15:18 AM PDT by central_va

January 1, 2010: By this date there would be complete ban on the production and import of R22 and R142b. However, there is exception for the on-going servicing needs of the existing plants and equipment.

January 1, 2015: By this date there would be ban on the sale and use of R22. There is exception for certain cases, including the serving needs of the existing refrigeration and air conditioning equipment.

January 1, 2020: By this date there would complete ban on the production and import of R22 refrigerant. The gas would not be available even for servicing of the existing plants.

After January 2020, the refrigeration and the air conditioning systems using R22 would have to depend on the stockpile of the refrigerant available with them. One just can’t really predict till when R22 would be available after the January 2020 deadline. It may also be available till the expiry of the equipment, but it would be surely lot more expensive. The owners of these equipment would have to either switch to the new alternative refrigerant or bear the costs of the highly expensive refrigerant R22 at that time or they may have to totally shutdown the equipment.

Yikes, that’s incredibly short-sighted.

saw a guy cut the refrigerant line and dump about 200 pounds of R22 to remove an air conditioning system.

We just discussed a recent report of a tech 'venting' R-22. He got caught. The business where he was working was fined an astronomical amount, he was fined and sentenced to several yrs in prison.

Wow. I knew it was a big deal, but YEARS in prison? Holy cow.

Re larger condenser, I fully expect regs will prohibit installing a larger unit than the energy laws will allow. I’ll probably need an engineer to sign off on the sizing and certify it I should Tiltle Blah-Blah compliant. Damn the government meddlers.

I think the problem is the old 80 to 60 drop is now 80 to 65 with the crappier refrigerants, thus requiring more airflow to transport the same amount of heat.

It’s weird they only want to change the return ducts (negative pressure) and not the supply ducts (positive pressure). Maybe they are worried about the return duct collapsing because of lower pressure near the furnace (higher airflow and velocity in same duct = higher pressure loss = reduced static pressure near furnace).

They didn’t explain anything. Off to other companies for competing bids.

They'd have to really spin the blower up for that to be an issue, don't you think?

Anyhow, good luck.

Nope same digital thermostat. I can’t figure it out either except the new unit just doesn’t work as well as the old original unit.
Thanks!

I did it when I needed to replace compressor and forget the total cast, but it was simply using MO-99 which is cheaper than R-22 to refill the system. But I think you can use it mixed with R-22 but not sure.

Bottom line it is cheaper and will work in an existing R22 system.

Yeah...I doubt if the squirrel cage blower could do that. It would collapse the furnace plenum, first, since it’s square.

I can’t imagine why they are concerned about a (maybe) 20% increase in air velocity in the duct and maybe an inch of water static loss due to the higher velocity. Methinks they are just gouging customers.

I found out how expensive after the recent heat snap. AC was throwing kinda cool air. Called a guy to look at it and was quoted ~$500 just to charge the system. R-22 is now over $100/pound. I know the system leaks and he said it could cost $700+ just to find the leak. We're going with new.

Well, temperature is temperature.

The only differences would the air flow blowing on you when it’s running, i.e. the wind chill.

And of course the amount of humidity in the air.

Even in a low humidity area, the difference between 20% and 40% is noticeable.

"I believe the idea of chlorine based refrigerants eating away at the ozone hole is the original environmental myth."

Actually, that problem may be the only one for which actual "smoking gun" chemical measurements exist to verify. But what was unexpectedly found once the original ban was in place was that the kinetics by which the active agent was removed from the atmosphere was much faster than their models predicted, and the last time I read about this in depth, the problem was largely gone.

"They’re a great way to cut back on wear and tear on your AC unit(s)."

Not if you have allergies (I grew up with attic fans). My wife and I live in western Washington, and we installed AC largely for the central electrostatic precipitator (both have really bad allergies...me to mold...she to pollen AND mold).

"We have to keep the thermostat set at 76 now to keep the same cool. 78 is just too darn hot."

Same thermostat, or new? If new, it may just be a sensor calibration difference. The sensors used are not the most accurate.

Same one. Digital. We replaced it a couple of years ago. Nothing has changed except the ac unit.

"These refrigerants are heavier than air and break down at around 1200 degrees F. How do they get into the upper atmosphere? How will they break down in the environment?"

Sorry, but this isn't true (or more accurately, isn't the whole story).

Yes, the Freons are somewhat heavier, but the driving force from concentration differences will still drive "some" molecules into the stratosphere. And there are other driving forces at work. Thunderstorms are also particularly effective in forcing vertical circulation, even of heavy molecules (Freons are not very soluble in water drops).

And yes, the Freons ARE very thermally stable. But the breakdown mechanism in the stratosphere is photochemical, not thermal. UV radiation is present in the stratosphere which doesn't reach ground level, as it is blocked by the oxygen in the atmosphere.

The primary culprit in the breakdown of Freon is the Flourine. Flourine reacts with almost anything. Here is an interesting fact, volcanoes put tons of Flourine compounds into the atmosphere when they erupt. When mount Pinutabo erupted in the Philippines, it put more Fluorine compounds into the atmosphere in its first few seconds than man had ever produced. The Pinutabo eruption lasted 38 minutes if I remember correctly.
The bottom line is that our mere presence on Earth is insignificant compared to what nature produces. Consequently, what we do as humans is pretty minor.

As a chemist, I am well aware of all this.

My first job task in my first new job after grad school involved hydrofluoric acid and silicon tetrafluoride (specifically developing instrumentation to measure both, which I succeeded in doing). An interesting assignment and real learning experience.

I am simply pointing out errors of fact in understanding about the ozone hole chemistry of certain fluorocarbons, which is, in fact, correct.

The overall impact of human vs other natural mechanisms is still subject to all the flaws of "model-based" alarmism.

Feedback control theory says the thermostat "should" drive the temperature back to the same sensor value, no matter whether the refrigerant is less efficient or not....it "should" do that by simply running the compressor a bit longer. So, unless the thermostat's internal sensor has jumped calibration (which is certainly possible), I don't understand what is going on.

Thank you.
I couldn’t figure it out. Our new ac unit is what I call a 2 stage which means the compressor runs shorter but then it blows all the cold out of the ducts before it shuts down to cycle again. I just figured that was it and it very well may be.
Our old unit shut down when the compressor shut down. Maybe that’s the difference. The compressor was running longer in the old one.
