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? If you think different, show me the science.

I don't think the insulated cooler is as necessary as something that
will hold the water after the ice melts. This is besides the fact I'm
just wondering if this thing works well and if it really requires that
much ice. 20 lbs an hour is not really an option when you are on a
boat, but if 20lbs would cool the cabin for a night that would be cool.

Waterproof cardboard. I'm sure it uses that much ice. Just think you
have to exchange thermal energy. So, you have to put a lot of heat into
the thing to get cool air out. That is exactly why an insulated cooler
is useless. You are blowing hot air directly into the thing, and it is
immediately expelled out as cool air. The replier that said I was
stupid must fail to understand this.
