[PSUBS-MAILIST] Air conditioner

[Alan]

That's a great find Joe,
It's designed for the environment & gives us an idea of size & amp draw.
It would be ok for surface transit but would need a through hull valve where it pumped water in,
that you could close before diving. I doubt the heat exchanging unit & pump would take
the ambient water pressure at depth. As said, the Triton Heat exchanger is outside in the water
& would ( I'm guessing ) just have fresh water at ambient pressure running through it.
   I like what Phil said they do, with the ice pads. There are all sorts of spaces you could pack
them in.

Powering the unit on the surface as I described in an earlier post. I don't propose diving with the unit running, but more so a pre and post mission environmental purge, particularly with the main goal of aggressively dehumidifying the cabin.
