Incidentally, a "ton" of cooling is the ammount of energy needed to

Please post corrections.

Your errors include the heat of fusion of water and its units, what a
"ton" of cooling is, trying to equate the two, saying that some amount of
cooling would "convert a ton of ice to water", and that cooling equates to
energy.

The heat of fusion of water is specified in units of heat/mass, such as
79.7 cal/gm, or 287 KBTU/ton. A ton of cooling is a rate of heat transfer,
not an amount of heat. You cannot equate the first to the second, such as
your saying it "works out" to some equivalence. Cooling is a rate of heat
transfer, not an "amount of energy" as you said.

Which all suggests you are a poseur when it comes to HVAC.
