Interesting but the problem is a leak where you end up with a nearly stationary gas mixture in the air, when the mixture reaches a certain ignited it can explode. Dont be fooled it can be very dangerous.

I've wondered about what the risk could potentially be in that situation because we must consider a worst case scenario too. I'm imagining something along the lines of an evaporator failing and suddenly leaking all the refrigerant out into a room and then a furnace coming on, someone turning on a gas dryer or lighting a candle, etc with the gas within its flammable range. No one seems to want to show that though, they just want to show that flowing gas is hard to ignite. That's good to know, but not the entire story.

There is a great deal of misinformation in the comments section. A2L refrigerants such as R-32 are not very flammable nor are they subject to explosion.

Ignition source? What do you think will happen when the compressor shorts to ground? These things are going to be responsible for so many deaths...

Every vehicle I know has their fuel pump submerged inside the fuel tank. Sending electrical power in a gas tank. Yet it’s perfectly safe. Because the lack of oxygen. If there is no oxygen, no fire. Same if a compressor shorts to ground. Everything is contained inside the system. Ignition sources inside the system, but no oxygen, there cannot be any combustion. So it will be like any other burnout.

Nothing would normally happen because there's not supposed to be any oxygen inside the system. But if there's enough oxygen, an explosion is possible. There have been cases of AC units exploding especially during pump down, but the incidents aren't specific to systems using R32. R22, R134a, R410a, etc also become flammable/explosive when mixed with air under pressure.

Who has the patent on R32? You guessed it. Daikin.

R32's been off patent for ages. R410a is like 50% r32 and the competing next generation refrigerants mostly contain r32 as well.

How much did you get paid to be bias on R32 😂😂. The real test is to put a restriction on the high side of a system till head pressure goes way up. And if the HP safety fails, Will probably blow up the house

How could the refrigerant explode inside the system with no oxygen?

If the high pressure cut out fails the compressor will stop. The danger is a slow leak that lets air ie oxygen into the system then you have an explosive mixture. A Permanant low side vacuum shut down is needed. I don't know if there is one but it is needed.

If it's nearly impossible explain all the KZitem videos showing R-32 systems exploding.

relax stupid murican. even non r32 ac's can and have exploded. r32's main benefit is that it has a lower global warming potential than r410a and uses 7% less electricity than ac's that use r410a.

Any refrigerant can explode if enough heat and pressure is applied to it.

@@acomman77 Exactly. Look up an MSDS for R134a, R22, R410a, etc and you'll see a warning that it can become flammable/explosive when mixed with air under pressure. The ONLY way ANY refrigerant can combust inside a sealed system is if there's a lot of air inside.

So basically a very small freon leak in the evaporator and a spark means the customer home goes up in flames. Absolute worst Idea
@averyalexander2303

If you are being serious, you totally missed the point of the video. A "very small leak" isn't going to pose any danger at all. Plenty of people's houses have small natural gas or propane leaks for many years without incident and those gases are undeniably MUCH more flammable than R32. No one thinks anything of piping a virtually unlimited supply of natural gas or propane into their house either. If the evaporator suddenly blew out then that might be a different story though, I haven't been able to find enough test data out there yet to say one way or the other.

The only way this could happen is if the entire charge of a typical R32 multisplit (say 4kg) leaks into a room less than 13m3 in size. That's a room 2.7m x 2m. What room in any house is that small but still has an AC unit in it?

The video is unpresentable. It promotes death, lack of seriousness towards technical standards in HVAC and good refrigeration practices. The saddest thing that happens over ASHRAE according to the characteristics of the fluid and its risks. a shame.
