High wall split air conditioners

[sridhar1312]

Recently at a residence a high wall room air conditioner burnt out resulting in immediate death of an infant and death of mother after few days. Boy recovered and alive.
what are the causes for such accidents ? is it due to incoming power given to indoor units or due to bursting of capacitor.

Would like to know the cause for such accidents and how it can be prevented?

There are several methods for death via air conditioning though all of them are extremely rare.

The refrigerant does not support life. If you have a small room and the entire charge of a large enough unit all leaked out into the room and there was zero turnover of the room air you could a suffocation issue.

When a refrigeration unit using a Freon as the refrigerant "burns out" the high temperatures that are present converts a lot of the refrigerant to phosgene gas. Phosgene is a deadly poison. So deadly it was used in WWI to gas enemy troops.

I doubt a capacitor fire would be sufficient to promote fatalities but I suppose anything is possible.

Before you come to ANY conclusions you should follow any investigation about this particular event to its conclusion. Oh and come back and tell what the investigation determines!
