Hi Alec.
Since tourist subs often have many passengers
aboard they have air conditioning to compensate for all the body heat. Also they
need an airflow of cool air to flow over each of the portholes the passengers
look out of so those portholes will not fog up
from the passengers being close to them and
breathing on the glass.
This wouldn't just be for the surface. How do they
do it? Just like the a/c unit in your car. With a compressor and condensor and
fan. I went down in a sub in the caymans recently and they had the a/c on and
directed at the portholes.
My dad's old gato class fleet sub from WW2 had air
conditioning too. You could probably rig up an a/c unit to work in a small
dry psub if you wanted to and had enough battery power. Hope this
helped.
Kindest Regards,
Bill Akins.

Actually this reminded me of something I've been curious about
for a
long time. With tourist subs, I often see they have "air
conditioning".
I presume this is when they are surfaced? Even so, I wonder
how they do
that?

Thanks Carsten &
Dan.
I didn't know if the metal hull of a psub was enough (or too much)
of a
heatsink to warrant additional hardware. I've seen many posts
regarding
the
condensation issue, and made the assumption that it must
get kinda warm
inside a small psub.
