I will use R 22 untill it is gone around 2040. I was intrested in the AMP draws I checked for my self a 5 Ton 13 seer R 22
system on 85 degree day it was runing 17 AMP's = to 68 60 watt Light Bulbs.
I also checked a 4 Ton 14 seer TRANE 410a system it was runing
24 AMP's. all systems remove humidy at the same rate of time,
24 AMP's = to 96 60 watt Light Bulbs This System uses a higer
suction pressure and a higer head pressure = to more Power use.
This will cost 2 to 3 times more to run in homes it is not good
for the economy home owners will be forced to open there Windows.
not good in the 21 century. It sure nice to know our Goverment
is looking out for us taking more money from the People and
making there pockits fater.

I don't believe in 911 conspiracies or katrina.
I dont stay an anybodys box,I have built 2 houses 3300sf next one will
be R 22 even if I have to custom build one!
I am 47 years old my Dad was in this Business when I was 10 years old.

120 watts =1 amp at 115v 115 = 2 60 watt bulbs 120 watts, 10 amps
*2 220 v = 20 amps at 115v.
This I can prove, I am a Licensed Contractor all you have to do check for your self, I have gone to a 410a class and the instructor
could not answer any of my questions.

Give it up already. Your sources are not official, much like your experiments. Why don't you just learn sbout r410a instead of condemning it, then you can move on like the rest of us already have!

read a few of the dukes and usualy agree but this time i will stand up and clap first off this guy is less then credable does any one beleive he found 2 comp systems operating with sim loads and just decieded to collect the rla . or did he just decide to make that up so he can stay stuck in his ways instead of educating himself
you guys forgot to mention the higher heat transfer rate allowing less raw material to acheive the same eff

I'd double check your measurements and be sure to include the air handler... it's a system efficiency concept. And depending on how well "tunedT the system is, you can have great variations in apparent efficiency. The SEER value are done under lab conditions so they represent the best ever possible situation. Poor installation, poor maintenance and other things can quickly degrade any system be it R-22 or R-410.

Actually airzone, You have made a mistake. It takes less energy to use 410a. The higher pressures are a result of the physical properties of the refrigerant, not the result of work being done by the compressor. Despite the higher pressures the compression ratio is lower on 410a. This means that it takes less comnpression to compress 410a. Less compression=less watts. In addition another reason 410a is more efficient is that it holds more btu's per cubic foot of vapor meaning that the compressor can accomplish the same cooling as with R22 with less vapor having been compressed which = less work(watts). Instead of doing uncontrolled experiments try reading a book or going to a R410a class like the proffesionals do. R410a is more efficient and environmentally sound.
The only disadvantage is in the case of a loss of charge. It is recommended to remove remaining charge and add new 410a(liquid). This is due to fractionating of the differnt refrigerants that make it.
Good luck topping off your R22 unit in 2040.
P.S. The government did not cause Hurricane Katrina, Aids, 9/11 or any of your other whacky conspiracy theories.

407c will replace R22 by Dupont.

Actually it does not have a fractioning issue. Some of the other 400 series of refrigerants due as some contain propane etc. Check this HRAI article for info:

yes it will be very expensive to try and keep using the r22 for much longer.oh yeah duke i found my low voltage short it was in the fan relay.thanks
