Exploding aircons and fridges, really ?
Youtuber NOBOX7 posted a video about aircons which have cyclopentane as a refrigerant, which is flammable gas.
https://youtu.be/F8IIpF0W128
The world's largest online chemistry textbook mentions Cyclopentane requires safety precautions to prevent leakage and ignition when used as a refrigerant as it is highly flammable. for this
substance. According to Nobox7, it decomposes above 600 F (330 C) to hydrogen and acetylene, which can be a hazard. If this were true, safety
requirements would prohibit the use of cyclopentate as a refrigerant.
Is this really true ?

Propane, butane, methane.
Any substance that can go from a liquid to a gas, with pressure change can be used as a refrigerant.
Keep the O2 out and there is no change of conbustion.

This guy is crazy!
For one thing, he refers to cyclopentadiene instead of cyclopentane when discussing the thermal decomposition of the latter:
Anyway, no, I don't think its true.
Although, as Rainwater says, cyclopentane could be used as a refrigerant, I don't believe it is, not commonly, at least.
I too saw a fridge dumped somewhere recently with a big sticker on the back that said "CYCLOPENTANE", and I got quite excited, thinking I could cut
the pipes and collect some cyclopentane in a bottle.
However, further research revealed that the refrigerant (R600A, the guy in the video says it himself) is isobutane, and the cyclopentane is used as a
blowing agent in the insulating foam that surrounds the fridge.
So I guess the foam is flammable, but the cyclopentane is not used as the refrigerant.

Possibly that he means this: the flammability of the insulation foam (if any C5H10 is still present in the bubbles).
