~Last summer while shopping for central air conditioning, I found that
~although room air conditioners are specified in BTU/hr, central air
~conditioning units are specified in "tons of air conditioning". It took
~a laborious net search and sending AC engineers back to their literature
~to translate this specification. Who in Phys-L has the answer?
~I believe that a ton of air conditioning is the amount of air
conditioning
~equivalent to melting a ton of ice per day. I did not do the conversion
~between BTU/hr and "ton of ice"/per day, but it shouldn't be too
~difficult. The latent heat of fusion is 80 kcal/kg and a BTU is the
heat
~needed to raise the temperature of a pound of water one degree
farenheit.

Dave, I think you are wrong. I do believe that Bob has it right.
One Ton Air Conditioning is approx. 1200 btus. I hope this helps you
answer
your question.
