WebAug 21, 2012 · Each chiller is designed to deliver chilled water at a certain flow rate with a certain temperature difference. Tonnage is calculated as follows: GPM x ∆ T︒ ÷ 24. For example, if the chiller has a flow rate of 550 GPM and the Delta T is 4.8〫F, then the tonnage would be 110 Tons. WebNov 10, 2008 · Cooling production is proportional to two quantities: water flow through the chiller and the temperature differential of the water entering and leaving the chiller (also known as DELTA T.) Mathematically, this may be stated as: Tons = (Q x DELTA T) / 24, where. Q = the flow of water through the chiller in gallons per minute (GPM.)

3 GPM/ton condenser water flow rate: Does it waste energy?
