Chiller Tonnage Equations and Guidelines   

Following is the basic chiller tonnage calculations used in the U.S. industry.  In most cases the process chiller efficiency is based on the evaporator tons rather than condenser tons.   For more chiller information contact: WWW.chillers.com

(GPM multiplied by "Delta T") divided by 24 = Chiller Ton ..........divide same by 30 = Tower Ton

(Pounds of water/minute multiplied by "Delta T") divided by 200 = Chiller Ton.....divide same by 250 = Tower Ton

1 HP = 2544 BTU's/Hour

1 gallon of water = 8.33 pounds

Kilowatt (KW) = (Amps multiplied by Volts multiplied by.85 multiplied by 1.73) divided by 1000

This electrical equation deals with 3 phase calculations.
