I had a nightmare once that involves chemistry, and I'm wondering if
it's plausible. If you're in a smell confined cell and someone
is pumping in lots of nitrogen, could it displace the oxygen and
suffocate you? Note there is a small air opening under the door,
so pressure probably wouldn't build up.
Nitrogen is slightly lighter than air or O2, so it will tend to rise
to the top. When O2 drops low enough you may pass out.
Helium would work better, as it would fill the room from the ceiling
and flush the air out the bottom of the door.

Re: a/c vs. the sun ...

It helps a bit to shut off the vent to the bedroom (and shut the door) until the evening to try to force a little more towards the "sunny side" but even at that, if it's a 93-100 degree day, and the sun is shining all day, the a/c runs continuously from about 10-11am until 7-8pm, then cycles very well even on recent very hot nights. ...
