[PSUBS-MAILIST] Air conditioner

[hank pronk]

Jim,
Batteries can handle it easy.  I have a 3,000w inverter and two golf cart batteries for power when we need ac on the job.  We can run a skill saw and what ever we need.  I like this better than a generator because we just turn it on and leave it all day.  It would be fun to experiment with a small ac unit.  I just don't have the need, I need heat, but that is easy.  You are probably right about not venting the unit.  I am sure there is a solution.

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.

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?
