hg = 79,385 Btu / lb

The cooling capacity saturated water table is the amount saturated water table of heat removed by cooling space. Designated in Btu / h, cooling tons or BTU. The cooling capacity of a cooling system-the ratio of heat removed from the space refrigerators often expressed in tons of refrigeration. The ability saturated water table of a cooling system that can freeze 1 ton (2000 lbm) of liquid water at 0 C (32 F) in ice at 0 C for 24 h is 1 ton. An example of how to calculate the cooling capacity:
A mechanical air conditioning system operates saturated water table so that the evaporation temperature is 20 F, and the liquid, near the valve, saturated water table is 100 F. Yes 10 lb / min of coolant recirculated 12, calculate:
hg = 79,385 Btu / lb
hf = 31.10 Btu / lb
ER = hg - hf = 79.385 to 31.10 = 48,285 Btu / lb
Capacity = 10 lb / min x 48,285 saturated water table Btu / lb x 60 min / h = 28971 Btu / h
T = 28971/12000 = 2.41 Ton
When one ton of ice melts, it absorbs 288000 Btu. Therefore, a pound, absorb 144 Btu. If a ton melts in 24 hours, it will absorb 288,000 Btu / day, 12,000 Btu / h or 200 Btu / min.
