At the boat show in Louisville about 5 years ago a dealer was selling small DC powered air conditioners. Can anybody remember to brand name?

Thanks for replying. I didn't know they were that pricey. I'll just run the old genny.

Even a DC air conditioner uses a lot of power and will kill your batteries in short order. IMO it's a gimmick. You can do the same job for less money with a 120v unit and an inverter (kill your batteries).

The one that I saw at the boat show was for a very small cuddy cabin. They said it would run 8 hrs from one 12 volt deep cycle. It was portable and it needed a 3"heat exhaust tube.

It would have to be a pretty small cuddy. Doing the math I'd guess it might be good for about 1000 btu, probably less. It might get you through the night, and then you have to charge the battery. Interesting, though. Any info on the critter?

No dear, But I can suggest you some DC powered air conditioner's dealers if you want.

Thanks anyway. Wouldn't be of any use to me, and the last thing I need is another sales pitch.

For the folks in the deep lakes, I've thought one could drop a pipe down to cold water and pump it up to a fan coil to cool the air. Wouldn't work for me though, the water temperature is 85F...

I wonder if this is the one? http://www.cruisencomfortusa.com/?gclid=CKbAtvy1xM0CFdgKgQodMNMOww

at 40-50 amps it would take some serious batteries to run all night.

I'll say. If you went in the middle at 45 Amps and ran it for a couple of hours to cool things down before going to sleep for eight hours, you would use 45 X 10 = 450 Amp hours (Ah) each night. The most you dare draw lead-acid batteries down is 50%, which means that you'd need a 900 Ah battery bank assuming full efficiency and a 100% charge each night. Even assuming that, you would need at least ten GC2 golf cart batteries to give a 900 Ah bank at 12 volts. A bank of 12 GC2 batteries would be more like it. That's a big battery bank. I can only imagine trying to get it charged each day.

I built a 12 volt portable air conditioner from a 36 qt. cooler, a 6" 12 volt fan and 6- 2 liter bottles of ice. The plans were on utube. In the small cutty it lasted for 8 hrs and was really comfortable. The next day you will have 6-2liter bottles of drinking water. Check it out on utube under homemade a/c
