[PSUBS-MAILIST] Humidity control

[JimToddPsub@aol.com]

Sean,

 

To pick up on humidity control in general which you mentioned:  This is a topic which affects a number of things in a sub other than scrubber performance and it's worthy of its own thread.  In a small one or two man sub powered completely by batteries it seems to be difficult to manage.  I'd be very interested in what anyone has to offer on the topic.  We've had a prior discussion on a portable cooling unit which would condense some of the cabin moisture.

 

Thanks,

Jim

In a submersible, the problem is more easily avoided, since it takes some time
for the cabin air to get close to 100% RH, and there are ways a designer can condense out or otherwise remove moisture from the cabin air to push it down. 
ABS standard is a relative humidity between 30 and 70% RH, and this is
probably what you should shoot for. (50% RH is often quoted as a desirable
target for human comfort in terrestrial buildings).
