How about having the sparker going as you introduce the R32. You may have gone past the stoichiometric point for ignition. That would be a proper test.

As a newb, un-brazed a line full of mineral oil with R-22. That was a nice big fireball. I can’t imagine doing the same with R-32 or R-454B. Always use a tubing cutter when doing a coil changeout.

Yes! Definitely be more careful with A2L refrigerants

Great video, thanks! Will share this with our guys. We are in the process of getting everyone certified but this makes the point clear. Looking forward to the next video.

But here in Europe R290 and R600 are being used in refrigeration, fridges and freezers, in many supermarkets as well. The industry does not care about technicians' safety.

How about when we braze the condenser and that copper pipe get heated is it dangerous, what do you guys recommend

Have you done a comparison between R-134a and R-1234yf yet? Id love to see those
@techoren51214 күн бұрын
R32 is fine. In Indonesia here, almost 10 Years since we start using R32 for Air Conditioner in 2015 and thers's no problem. Portable air conditioner here start using R290 since last years and as you know, Europe will start to massive using R290 for heatpump in 2025

Loved this video ! I thought of making one like it and now I don’t have to lol my take away is that they are both flammable. Idc about “mildly “ because that’s like saying someone is mildly pregnant. I saw fire on both.

I miss old R22 systems, built to last. R410A will be the last of the good refrigerant

R32 is fine

Main danger is not sparks but arc. It ignites much better than candle flame.

Please check about the 2.5 ton hot and cold model of fujitsu general and there compressor rating.. Is it upto the mark
@AAAA-oe4ii4 ай бұрын
Try some r-32 , compressor oil and air mixture in your test chamber.
@GWAC5554 ай бұрын
Yes! Mixture of oil, pressure, refrigerant and air in the system can complete the combustion triangle. If air is not present it will never result in combustion. Technicians should never skip pulling vacuum.
@robertmitchell8324 ай бұрын
With the open flame, you need to allow the gas to fill the chamber to reach the flame.

It's still flammable. You still need to mitigate the concentration of propane which is highly flammable.

Please do R452a that cointains r1234yf
@GWAC5554 ай бұрын
R452A is a mixture of 11% R32, 30% R1234yf, 59% R125. This is a non flammable A1L refrigerant, R125 is a flame suppressant, when mixed with mildly flammable refrigerants it will make the mixture non flammable. Just like R410A is 50% R32 and 50% R125.
@neilafram663Ай бұрын
You need to be aware that both R32 or R290 are and can be INTERNALY be EXPLOSIVE (ignition temperature of lubricating oil at the compression cycle) in the presence of air or water. This will not happen if A1 class (like R410A or R513A, R134a etc) . By the way did you know the only reason A1 class (CFC 22, 12, HFC22, HFC410A etc) was SAFETY and since 1928.
@neilafram663Ай бұрын
Why use either if flammable/explosive when there are over 90 A1 class NON-FLAMMABLE, NON-EXPLOSIVE? and they are more efficient no extra safety...... Also there are no laws or regulations will ban A1 class. You test is a testament to its dangers!!!
@jeffstewart95684 ай бұрын
People are forgetting that you need to have all three sides of the fire triangle to ignite a flame things don't just spontaneously combust. These systems can be completely safe.
@stefanstix51764 ай бұрын
The concentration of the r32 was too high to be in the range of explosive mix. Between 13,5 and 27%Vol in air it is explosive. Below and above it's not. Try that again with 20% Vol.mix in Air 🤪

R290 dangers. Compare that danger with a leaking BBQ grill or a gas stove with a leak.
@GWAC5554 ай бұрын
The propane and Natural gas used in BBQ grills and stoves have an odor added to them so we can detect a leak. R290 has no odor whatsoever.

Hmmm, one people commonly associate with a risk of explosions, the other people don't think much of all. I'll let you guess which one AIR CONDITIONING is.

Mo99 for R-22 replacement, but isn't efficient as R-22 & will have a higher energy cost compared to R-22. R-32 is probably going to get banned in the US soon as its already banned in the EU. The US is banning R-410A & companies are still selling R-410A units!

Thank god mexico with all it's lack of regulation exists. Everybody wants a closed border until it's time to do closed border shit. I prefer my ac with the smallest side of fireballs possible, in home and auto.
@wrestlingterrier8366Ай бұрын
I live in Europe and R32 is not banned, if anything it's becoming more and more common just like R290 and R600. Many Minisplit ACs are using R32 in Europe right now. I personally do not consider them as safe refrigerants. They are not.
