RE: [PSUBS-MAILIST] Cabin heat (take 2)

["Alec Smyth" <Alec.Smyth@compuware.com>]

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.
