Looking for a shallow depth A/C[Cross Post from ConsumerAdvice]

Living in NYC with a fire escape on both windows in my room. Law states that I can't have an A/C unit that extrudes too much* to block the path of the fire escape in one Window. My room is around 190 square feet. I've tried to find small depth A/C's. I've also looked into models that evenly distribute their depth internally vs externally(Example) That youtube video claims it's an old Carrier 6000BTU unit.

I've tracked down a few shallow units, but none of them are more powerful than 5000BTU, and they're quite old. Is this considered an outdated design? I know the further back it is, the quieter it operates, but are there any other drawbacks? Anyway, here are some A/C's that have an acceptable external depth:

So I've listed three A/C's. Why am I making this post? These models are old. 5000 BTU's might not be enough for a 200 square foot room. Are there any models out there with similar design(or shallow external depth) that are at least 6000BTU. Or maybe even newer?

Thank you for reading.

TL;DR: Looking for a 6000BTU+ unit with shallow external depth

I've also looked into portable A/C's, but I would prefer to find a window A/C solution if possible.

*Not exactly sure on what's the limit. Hard to track down.
