Does anyone have any experience using one of these 12V portable AC
units on a boat. They look like a good option, but I was curious if
anyone had any feedback on how they cool and how much ice they use.
The website says 20lbs an hour which is a lot, wondering if anyone has
used this before. http://www.swampy.net/ac12.html

I'm wondering why the ice chest? Just to pump hot air in and suck cold
out, might as well use a cardboard box.


You're not really that dumb, are you?

What difference would it make? The function of an ice chest is to
insulate. If you are pumping hot air into it, why would you need to
insulate it?

This unit works by pumping cold *water* through a heat exchanger, not air
across ice.

If you think different, show me the science.

The science is basic- heat always moves to cold.
The cooler is insulating the ice from absorbing heat from whatever it is
resting on, thus saving the ice for where it can be used more efficiently-
in the heat exchanger.

Horse****!!! The science is cold is simply lack of heat. You are
blowing the same exact air across the ice that the ice would be exposed
to. If you are pumping 90 degree air into that cooler, what difference
would it make whether or not the container was insulated??? Try it.
Take a given amount of ice and put in a ice chest. Place another in a
cardboard box. Blow the same exact amount of air into each, with the
same exact equipment, and the same exact exhaust. Measure the
temperature of the exhaust. Guess what? They'll be the same.
