[PSUBS-MAILIST] Cooling the cabin: a suggested solution

[Marc de Piolenc <piolenc@archivale.com>]

The obvious solution for restricted spaces with DC electrical power 
available is thermoelectric (Peltier effect) coolers. They are, however, 
tricky to design - the modules sold are always optimistically rated, so 
the user has to do his own analysis to get the best possible COP, which 
will not be high in any case. They're also not cheap, but neither is any 
other solution for this particular application.

Of course there has to be a way to remove heat from the hot side of the 
modules, which implies a hull penetration for a cooling loop, and very 
careful protection of the modules from corrosion while maintaining good 
heat transfer.

It's how I would do the job, though, if it were my sub. No moving parts, 
and once it's designed and built, you're finished. There's no 
maintenance, no refrigerant recharge (and none to leak into the cabin).

Best,
Marc
