Q = 500 BTU per gallon per hour X 40 GPM x 12 ΔT = 240,000 BTU per hour 3) Convert result into tons of chiller capacity. Divide Q (BTUs per hour) by 12,000 (the number of BTUs in one ton of cooling capacity). This yields the chiller capacity required to handle the process heat load in tons per hour: Example: 240,000/12,000= 20 tons/hr.

· The GPM/ton rates you are talking about are "rule of thumb" numbers. Typically for chillers systems, 2 GPM/ton is usually the evaporator flow and 3 GPM/ton is usually the condenser flow. These rates came about because they correspond to the temperature change of the water in the system. The 2 GPM/ton evaporator flow rate is a system with a 12 degree delta T ( 44 degree supply water
