Insulation inside the sub

[Dick Morrisson <rmorrisson@unidial.com>]

Insulation will help reduce condensation on the inside surfaces of the hull,
but the dome and/or view ports will still have condensation unless the air
inside is dried to the dew point of the water temperature they are exposed
to.  Is there a standard dehumidifier available and in general use for small
subs?  Can the air being circulated past the CO2 absorbers be run past a hull
surface at a slightly higher pressure to allow it to condense and dry it out
before scrubbing it?  Does the effectiveness of the scrubber vary with
relative humidity?  Perhaps even a small refrigeration unit could cool the
air being circulated to dry it then add the heat back in to bring it up to
normal temperature before scrubbing.  These units are very efficient and
reliable, some are even single chip electronic types.  Thoughts from the
group?
