[PSUBS-MAILIST] Air conditioner

[JimToddPsub at aol.com]

Hank,
 
The closest relevant experience I've had was with the A/C  units on a motor 
home.  I always had to run the generator if I wasn't  plugged into shore 
power, so either way the A/C was running off 120v; batteries  couldn't handle 
it.  On a tender I'm planning on a small  A/C configured as a portable unit 
of the right size to meet the need.   Too large a unit (BTUs) can drop the 
temp without dehumidifying.  
 
A flat disk covers the open hatch, and a duct runs from  the A/C unit 
through a hole in the disk.  Another hole in the disk allows  the warm, wet air 
to escape.  Depending on the circumstances, it may or may  not be best to 
duct the return to the A/C unit so cooled air is recycled through  the unit and 
progressively stepped down in temperature.
 
Dang it was cold when I got back to Missouri!  Made  me want to turn around 
and go back to Florida.
 
Cheers,
Jim

Scott, 
I think it would be simpler to run a house AC unit off an  inverter.  It 
takes at least 5hp to drive an AC pump in a vehicle.   You can also get 12V 
coolers that might have some potential.  I have the  opposite problem, cold, 
at least we can dress for cold.
Hank

I know basically nothing about HVAC. I am assuming taking a compressor  
outside of a car and running it on a 36 volt motor and running the tubing on  
the outside of the sub to disperse heat would consume to much power right?  
Anyone know how many amps at 36 volt, 24 volt, and 12 volt would be required  
to do something like this?
Thanks,
Scott Waters
