[PSUBS-MAILIST] K350 motors and housings - available

Tue Apr 2 12:44:59 EDT 2019

The DC compressor & water cooled condenser are the most expensive items.
If your a DIY'er, go to your nearest "Pick & Pull" get a car AC compressor add a DC drive motor, condenser & evap coil and roll your own.  It will take 2 HP to full drive the compressor, however you can vary the speed and control the cooling, while minimizing current drain. You'll need a refrigerant detector as a leak will kill you in the confines of a PSUB. Or go thermo electric.

        Thanks for the links,  The MES24S - 24V unit looks like it would work great but at  $3,895 , I am not going to be ordering in the near future. In the spirit of Psub and DIY, I wonder how hard it would be to design and build on of these units.  Seems to be made up of readily available parts like a compressor, blower, coil ....

        To me AC on personal subs is an interesting topic.  As the Psub community frequently dives off Islamorada Florida, it is a relative thread.Below is a graph taken from flight recorder on the R300 during a Psub dive off the coast of Islamorada in August of 2017.

 It got very hot and humid during the 4.5 hour dive.  Note that the cabin temperature reached 96 F, the relative humidly reached 85% and the heat index reached 146 F.  To say that I could have used small AC unit in the boat is an understatement!  One of the implications of this cabin environment was that I could not keep the viewport clear.  I soaked the towels I had on board very quickly trying to clear the viewport.  As a consequence, is was hard to see.  
There are challenges in designing a AC system for small subs.  Ideally, it would be self contained and easily removed for service.  The unit is going to have a reservoir for capturing quite a bit of condensed water extracted over say a 6 hour design mission time.  For my boat the unit would need to be small and compact.  Would be nice if we could find a OTS small compact AC unit that was DC powered. 
If any one knows of a small compact AC unit, send me the link.  I would like to test in my boat.

And it occurred to me, while we discussed air conditioning systems on our personal subs, we were likely the only three people on the planet having that conversation. 'Tis a small collection of fellow adventurers.
