[PSUBS-MAILIST] Air conditioner

Hank,
I wouldn't have expected that batteries could handle running  an A/C unit 
for very long, but it would be really nice to not have the noise or  exhaust 
fumes from a generator.  Sounds good.  Now about running the  microwave, 
too...

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 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
