RE: [PSUBS-MAILIST] More Dehumidifier



Well now...looks like my fears about conditons here in "muggyland" are confirmed!

Dan,
 
You should try it in Florida in the summer! The amount of condensation was such that I had electronics shorting out after just a little while. I was so wet, when I look at video shot inside the sub I look as if I'd been for a swim with my clothes on.

I agree with Jay,
 
I recently installed a 12 volt equipment fan in Persistence to make it more comfortable.  I believe mine is rated at 100Cu.Ft./Min.    A 70CFM fan would have been enough. 
 
High humidity makes it mighty uncomfortable but all it takes is some air movement and it feels much better.  When in the water, the cool hull condenses much of the humidity out of the air.  What moisture that beads up on the hull from a day of diving never amounts to any actual water sloshing around.  After a day of diving I just leave the hatch open and it's all evaporated away the next day. 
 
I don't think there is much need for a dehumidifier in a P-sub.  If the cost and power consumption were minimal and it took up little space, it might be nice but just moving the air around inside the hull makes a big difference.  
 
Just my opinion,  Dan H.

Patrick,

Very informative article but almost all of it doesn't apply to PSUBS.  While there is a small amount of moisture entrained in the atmosphere upon closing the hull up, the majority of moisture throughout a dive results from respiration and perspiration, (and God forbid if you should have a leak J).  A submersible is cramped for space and constrained by available battery power.
