"THE CALIFORNIA DAILY WORRY GAZETTE"
story by: Spot Tedowl, Reporter
Today the governor of California, Cameron Diaz, has stated the demise of all chemical refrigerants in the state, due to the recent deaths of millions of brown cockroach's in apartment buildings and other community living sites.
The brown cockroach brownius cockroachius), was a common pet among the children of California, and parents were getting tired of telling thier children they were living on "uncle Ralphs farm".
Gov. Diaz said rersearch from UCLA has indicated the potential harm from chemical refrigerants to the roaches and stated "duh, if you can't club a baby seal then you can't, like, kill, like, a kids pet, you know?"
California is proposing that we no longer use chemicals, but, Evian, for all future refrigerant needs.
The governor also said her nine year marriage to Billva was incredibly "fantabulous" and that he is the "bestest" husband a woman could dream for.
nobody knows what will be developed tomorrow in the world of refrigerants. today 410, tomorrow ?
for the next 25 years we'll have our choice of 22 AND 410.
i'm personally going to stick with 22 for my families and my own systems for now. and only if a customer insists on 410 (and there are only a handful that have) will it be installed. at a greater initial price, of course.
Count me in R-22 loyalty.
Doc Shakes his head in amazement...
I found the definition here... http://members.aol.com/nonverbal3/headshak.htm
Gesture. 1. Rotating the head horizontally from side-to-side a. to disagree, or b. to show misunderstanding of a speaker's words. 2. In an emotional conversation, a rhythmic, side-to-side rotation of the head to express disbelief, sympathy, or grief.
Usage: The head-shake is used to demonstrate a. cognitive dissonance, or b. emotional empathy.
I am sooo confused.
I just don't undestand the resistance to 410a.
All you really have to do, is treat it the way we were always suppose to treat 22.
So the pressure is alittle higher. Brazed joints can take alot more pressure then a 410a systems running pressures, so thats no big deal.
Come 2010, and the choice is gone.
Although allowed to produce 22 till 2020, who knows what the price will be. You could be paying twice as much for 22 in the future as 410a. Meaning you aren't doing your customer any favor by not offering them the choice.
Ok, liquid charging only, some will have a hard time getting use to that.
In the place I work we have a Co2 fire protection system that uses R-404A refrigerant. This has to be charged as a liquid. Unless, I am mistaken, the only difference the charging procedure between a R410A system and a R404A system is the higher vapor pressure of R410A.
Your right, 404a is a liquid only charge refrigerant.
So what is R410a exactly? It's a near-azeotropic 50/50 blend of R32 and R125. Some seperation of the 2 components can occur in the vapor phase, but not enough to cause a significant change in the composition of the refrigerant with a refrigerant leak. IF a leak (small) is discovered the system can in fact be "topped" off.
This information was taken from R410a pub. # 34-4066-04
Recently attended yet another class on R410a, and am still amazed at the number of people that seem to be either against it of affraid of it.
"If you can't fix it, don't break it."
Thanks Duct Dr.
I agree 100%. But I think the conspiracy theorists will still not accept it regardless.
BTW, Happy Easter.
410a classes in phoenix, az.
anyone know of 410a classes in the phoenix area?
Very welcome doc, and Happy Easter to you also.
"If you can't fix it, don't break it."
Has anybody taken a look at the price increase for R-22 over the past year? I think we might get forced into a complete changeover to R-410A sooner than some may think. sure they are comeing up with some replacements for R-22 but from what I have seen of them so far they are absolute junk. We may eventually see replacements for R-22 that will work as well as some of the replacements that were developed for R-12, R-502 but remember we lost some capacity with most of these. Personally when I replace the old Lennox A/C, a new system with R-410A will go in it's place. The manufacturers have various criteria they use when choosing what refrigerant they will use, it is up to us to adapt, those that don't will find themselves left behind. So far I have had fewer incidences of leaks with R-410A equipment than I every have had with R-22 equipment. R-22 was very forgiving when we didn't play by the rules but if we do play by the rules with R-410A I have seen even fewer problems than we had with R-22.
people are not afraid of 410. we have a proven reliable product with 22.
if it aint broke, don't fix it.
Hey I just like working with 22. I'll use 410a when the time comes, I have no qualms, fears or conspiracy notions about it. I work with all kinds of refrigerants, 410A no differant to me. Just loyal thats all.
