Had a ideer for a A/C system

30 degrees? Talk is cheap, I say

Here's a little on A/C. You might have heard the term so many "ton" or "tons" of A/C. A "ton" of A/C is 12000 BTU/ hour. That is in theory the amount of heat it takes to melt a ton (2000 US pounds) of ice from solid ice at 32F to all liquid. This is the SAME IDEA as discussed above in regards to the heat required to boil water, known as "heat of vaporization" or "enthalpy of vaporization" except, now, instead of "changing state" from liquid to vapor (or reverse) we are now "changing state" from solid to liquid (or reverse)

For ice to water, (or any other substance from solid to liquid) this term is "heat of fusion" or "enthalpy of fusion"

Where vaporizing water is 970 BTU per pound, water's enthalpy of fusion is 144 BTU per pound. So you multiply 144 BTU X 2000 LB (of ice) and this gives you 28,8000BTU. You divide this by 24 to get to "an hour's worth", so 28,8000/ 24 = 12000 and we have our "12000 BTU / hour"

THE POINT IS THIS

A 12000 BTU AC unit is NOT very darn big. Most small, cheap "window bangers" are somewhere around this capacity, and as you surely know, they won't cool much of a space So think about that tiny, cheap "window banger" as being a real live ton of ice out there melting away.

One figure I've seen rates "typical" auto A/C systems at 4hp, or somewhere in the 3-4 ton range, not a toy, but other figures show more like 1 1/2 ton, or about 18,000 BTU/hour

The "REALLY BIG TEST" for any of these ideas people have is simply this:

If this is such a great idea, why isn't everybody doing it?
