DEF

The amount of energy it takes to convert 2000 lbs. of water at 32° F. to ice at 32° F. during a 24 hour period. Calculation: 2000 lbs.H2O x 144 Btu/lb. = 288,000 Btu's in 24 Hrs. Divide by 24 hrs = 12,000 Btu/hr. Therefore a "ton" of cooling is a measure of heat energy which is roughly equivalent to 12,000 BTU's.

CONT

One ton of refrigeration capacity equals 12000 BTU/HR.
