New one on me

[Mike(NEOhio)]

The wife bought a small refrigerator last week for the basement. A very large sticker on the back about the refrigerant, CYCLOPENTANE with a warning about flamability. Haven't heard of this one before.

Yes our government is at work. Wife’s uncle used to recharge his car lot cars A/C systems with propane because 134a was too much money. My new deep freeze has the same stuff.

Im pretty sure that cyclopentane isn't used as a coolant, its used to install the foam insulation.

Although it could also have an a2l or a3 refrigerant in it

Even if the hazard label was for the newest flammable refrigerants now it’s not like propane we had to do training on some of this about a year ago it’s “flammable” it will technically catch fire pretty much if the car is already a rolling inferno it’s not like it will light super easy like your grill. Ul had some good videos that are probably accessible to everyone

It’s likely that the insulation is very flammable

If its r290 its exactly like propane
Just a very small amount in modern refrigerators

Cyclopentane is used as a propellent for applying foam insulation.

It is also used as a refrigerant and is highly flammable.

The designers can't think beyond their lab testing. It's a sealed system so it doesn't matter if the refrigerant is flammable. They can't understand that things get old and leak.

FWIW, R410a is being phased out and new R410a appliances are not longer made. It replaced R22 a couple of decades ago, but has now been superceded by R32. R32 is flammable.

That must be what's in the AC on our car. I had to have a new alternator put on it. They said the AC compressor had to come off first and they didn't have a pump yet to pump it out. They said they didn't want to start fooling around without it pumped out because it's flammable.

no sir, that is R1234yf, still flammable, and the machines to recover and charge them are stupid picky about contaminants, also the stuff is insanely expensive, runs between 6 and 8 hundred bucks for 10 pounds

It is true. For years propane or butane has been used as a refrigerant gas. The company I retired from packaged turbine engines to York Compressors used for chilling natural gas in gas plants to get the liquids and vapors to separate. Yes it is the same York as York Air condtioners. The amazing thing about this is how the ice would build up on the cold end of the York as it ran. Even in a hot engine room, ice would form and stay on the machine as it chilled the propane down to well below zero. I spoke to a plumber and he told me that the main reason they are going to that type of gas is to decrease chlorine vapors released into the air. I guess swimming pools are ok.

I saw a video of what looked like a fairly new refrigerator blow up in a kitchen. There was security camera mounted and caught the whole thing. I didn't realize the new stuff was so flammable.

Hey, lets hear it for those highly educated engineers. Looked good on paper.

I saw that one, or a similar one at least. It was a new refrigerator that had a problem of some sort. Repairman worked on it but didn't finish. Closed it up and left for the day.... Boom!

I'd bet it had a leak on the interior coil so that tiny amount of propane was contained in the inside. Near perfect air/fuel mix. Defrost timer closed or opened making spark.

He should have unplugged if it wasn't working correctly.

He, the seller and manufacturer were lucky in that the ignition source was a timer and not the user opening door triggering the light to come on.

I'm game for when NH3 gets used. Best there is for making yer A/C an ice box.
Bonus is, you'll know instantly when the evaporator starts to leak.....
