Cooling Alternatives

 Hey guys, I was wondering what those of you that are off-grid use as an air
conditioner alternative?  Swamp coolers? DC Fans? Are there any air
conditioners that run on anything other than AC?

 

I use a solar PV powered DC fans for cooling during the early part of a
summer day, thus saving the amount of time I would need to run an air
conditioner.

As for air conditioners. I don't know of any that run on 12 VDC. The
component of an air conditioner, or an air conditioning system that uses the
most power is the compressor motor. I suppose you can find DC compressor
motors, but you will have to look.

 

  One of the more cost effective devices I have seen is a solar powered
gable fan. It goes in the attic and vents out at the end of the house. =
This
keeps the attic cooler and the solar panel mounts right on the roof =
above
the gable, which cuts down on the wiring.

ceiling fans and very little clothing. Of course 100f is a rarity around
here. if it gets too bad, it's road trip time in an a/c equipped
automobile to the beach (a bend in the local river). Mountain water
doesn't much above 70F even in summer.

 There is an auto airconditioner outfit that makes electric ac
compressors for old cars. Also marine ac units might be usable.
