I hope my question is "scientific" enough for this group!
My freezer has a fair amount of extra space in it. Easily, a couple of cubic
feet. I'm thinking that the cost of putting water in that space, or some of
those blue ice packs, isn't going to use a lot of extra electricity.
My office is in a spare bedroom in my house. It is just over 200 sq ft, and
the ceiling is 8' high. The house is kind-of built into the side of a
mountain so the insulation is pretty good.
It isn't necessary to cool off the whole room. I'd be happy to just keep the
area cool where I sit. I'm thinking that it would be nice to lower the
temperature by as much as 10, maybe 20 degrees F.
So, my idea is to freeze some water (or whatever), and then drop the frozen
blocks into some contraption that I build out of a Styrofoam cooler and a
fan. My idea is cool water with ice, and then blow air through the water.
Alternatively, to avoid humidity, I might try to rig some sort of radiator
system so that I'm not just pumping water into the atmosphere and making
Is this a reasonable idea? I imagine that I could use BTU calculations to
determine whether or not this is feasible. Could somebody please clue me in
on the math?
