A ton of refrigeration is the amount of heat removed by an air c onditioning system that would melt 1 ton of ice in 24 hours.
1TR = 12,000 Btu/hr
One ton of refrigeration is equal to heat extraction @ of 200 BTUs per minute, 12,000 Btu per hour or 3025.9 Kcal/hr. This is based on the latent heat of fusion for ice which is 144 Btu per pound
