Re: [PSUBS-MAILIST] idea
Hi David,
my radiator idea might work for an ambient but in a
1 atm sub
the radiator would blow apart with the water
pressure if too deep.
You could run the water in to a reservoir
& suck it up through the radiator
with a pump between the radiator & the outlet but it
would drain the electricity
pumping against the outside water pressure & be a
bit dodgy.
I was rethinking the heat issue also after seeing
Doug's sweat box.

Vance,
Take the time to give Alan's
idea a look...makes better sense to use the cold water and simply reuse it
with a pump. A great how-to set of instructions
too.

Dave,
That is almost exactly the semi-stone age air conditioning unit that
Wil and Charlie Kohnen install on all the Seamagine subs. It works like a
champ, and I suspect you will see one aboard Gamma pretty soon, as
well.

To all: Not sonar related but...
It is said that
necessity is the mother of invention...
The only dive I
have ever been on aboard a small submarine was hotter than hell. Nothing
against this sub captain or his submarine as I feel all small submarine
experience this problem when working in warm water and in the Summer
months.
Solution?...
A small
container installed aboard this submarine thru the already available access
hatch and set upright and out of the way. It appears as a small cooler with
an easy to open upper lid.
Prior to diving, this lid is opened
and a small bag of ice or perhaps several is simply poured into this
opening. It lands on a screen about 3/4 of the way down into this opening.
This lid is then closed and a small toggle switch is then turned
on.
A 12 volt dc fan draws air from an intake port above this ice
and is supplied by a funnel such as is used on household clothes
dryers from perhaps somewhere aft in the submarine. This air passes thru
this ice and into the this fan which exhaust it again into a tube sent
forward perhaps to several exhaust ports.
As this ice melts, the
condensate drips down and is collected into a pan at the units base. This
pan is designed to slide out once full for disposal of this collected water
of perhaps 2 gallons. A high water level alarm could be installed as an
extra.
At the dives end, this collected water is simply slid out
and thrown over the side as fresh ice is again installed into the units
upper lid assembly in preparation for the next dive.
Of but the
power used to circulate air, no addition power is used to operate this
device so it is not much of an additional drain on the boats electrical
systems as would an actual ac unit.
Although not perfect, this
device should lower the temperature enough to make diving a bit more
comfortable for both the submarine operator and that of his
passengers.
Does this device seem worth while to
develop?
