Can air conditioner explode?

For answering this I am dividing AC into two parts. The one that fits on the window (window type), and the one that fits on the wall (mini-split). The first is one piece, the second is two pieces (split)–one part is outside the wall, and the compressor (detailed below) is outside. The faucet hinges on the window AC are all in the same box, but the compressor is on the outside, not the room. But both types of AC basically work in the same way.
How does AC work?
Seen to pick up water with clothes from the floor? Or seen mopping the floor?
There is water on the floor, a cloth absorbs the water, then the cloth is crushed/wrung out to remove the water.
For AC, the water is the heating of the house, the cloth is a kind of chemical, which is called refrigerant.
The refrigerant absorbs the heat, then the refrigerant is crushed/twisted to expel the heat from the refrigerant outside the room. A machine called a ‘compressor’ works to compress/compress the refrigerant. As the name suggests, it compresses. By the way, the fridge works the same way.
Refrigerant is in liquid and gas state in different parts of AC. By absorbing heat, it becomes a gas, compressed in a compressor and becomes a liquid again.
– We all understand that when gas pressure increases, pipes can burst.
— If the pipe is blocked/narrowed for any reason, the pressure may increase
— Pipes can burst even if the dirt accumulates around the overheating.
The compressor can also burst due to the same reason. If the compressor of the mini split bursts and can injure people on the street below, it will not break through the walls and enter the house. A window-type compressor rupture can injure people below and people in the house, but injuries inside the house are less likely.
The mini split has a gas pipe (coil) inside, so it can crack but not explode.
Rupture from such causes is rare. The rate at which news reaches Bangladesh is ridiculously rare.
How much damage can a metal pipe or compressor crack? The damage is much less than if you hit a brick wall with all the force of another brick, because the broken pieces weigh so much less. However, a direct hit to the human body by metal fragments can cut, and can be fatal. It is not impossible to enter by breaking the glass of the window.
But again, it cannot break the wall.
Q: Can AC gas cause a fire?
Answer: Not possible. Common refrigerant gas can suffocate people, but it does not catch fire like stove gas. But there is a “but”.
There is a refrigerant called R-22a, which is a mixture of LPG and butane (cigarette lighter gas). It catches fire very well.
Couldn’t find if R-22a is sold in Bangladesh.
If the R-22a continues to leak, it may catch fire due to an electrical short circuit or other cause.
