Things you can do if you use R32 gas AC in you room? 1. Turn on the fan of the room to circulate air. 2. Use the AC at 27 temperature setting. 3. Remain slightly open the door or window of your room to exhaust the possible leakage of R32 gas especially during night. 4. Check the gas leakage once a month during the summer season by an AC specialist. 5. Do not use the R32 AC heater function in winters. 6. Do not relocate the R32 AC unit to a different room. This will rupture the pipes causing gas leakage. 7. Once the inner unit gas pipes leaked, replace it with a brand new AC kit or throw away the AC and get a new one. 8. Always use a brand new R32 AC.
With the exception of #7 (presumably meaning not trying to repair a leaking evaporator), that is the most ridiculous comment I have seen in quite a while. Even #7 is only partially true. Yes, trying to repair a leaking evaporator generally isn't a great idea regardless of the refrigerant, but there's nothing wrong with simply replacing the coil. No need to replace the entire unit.
I think in Pakistan Gas suppliers are mixing some propane gas to reduce cost of R32. If high quality R32 gas is used such kind of explosion is unlikely to happen. Well again, this is only my guess.
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.
May 2024, Daikin's website shows R32 units are still not being sold in the USA. Any idea when they will switch from R410a to R32? Or in the alternative, any idea when the website will be updated to reflect reality?
I hate these flamabiIty tests, these geniuses forget one big thing, the flamible gas travels tjrough the system with flamabile "OIL" mix r33 and poe you get napalm . Redo yhis test with r32 mixed with poe oil
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.
@@jakbo_ No problem stating the safety of the A2l refrigerants. The customer's propane grill is more than 10 times more dangerous than R-32 or R-454B which cannot be ignited if connected to their own grill even if you tried to get it started with a propane torch.
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?
Daikin ambiguous Miss two vital points: diesel effect which leads to explosion and the fact that it is a fire propagator. They Ignor international standards ISO817 and ASHRAE34 and BSEN 378 and AHRI 2021 done by UL?? A joke!
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.
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.
@@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.
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
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.
