THINKING OF REPLACING YOUR AIR CONDITION[ER] WITH ICE?
HOW STUFF WORKS - How much ice would I have to store up in the winter
in order to air condition my house all summer?. . . This is a great
question... . . . It certainly would be an easy system to build. All
you need is a big insulated container (probably in the form of a hole
in the ground) with some coiled tubes at the bottom. You would run a
chilled water circuit from the container to a radiator inside the air
conditioner (see How Air Conditioners Work for details). You would
need a small pump to pump the water in the chilled water loop, but
that's it.
[The math follows and then the conclusion]
So we need: 130,000,000 BTU * 3.15 grams/BTU = 409,500,000 grams of
ice That's about 410,000 liters of ice, or 410,000 kilograms (902,000
pounds) of ice that you must store to cool your house all summer.
That's a cube measuring 740 centimeters (24.26 feet) on a side. Very
roughly speaking, you would have to dig a hole as big as your house
and insulate it well, and then in the winter you would have to shovel
it full of nearly a million pounds of ice. But if you do that, you can
cool your house for free.

bc, who hasn't checked it, because he must house, as in house husband.
