WebAlternatively, you may use a rule of thumb of 3 gpm per refrigerant ton (RT) of cooling capacity. For example, my building needs 2,400 RT of cooling capacity. Using the rule … WebDec 29, 2024 · If water enters the chiller at 64 degrees Fahrenheit and leaves at 51 degrees Fahrenheit: 64 - 51 = 13 degrees. Step 2. Multiply the result by your flow rate, which is measured in gallons per minute. If, for instance, the chiller must move 300 gallons per minute: 13 x 300 = 3,900 gallons per minute.
WebJan 16, 2024 · Optimizing condenser water temperatures . With a constant temperature differential, reducing condenser water flow rate increases the efficiency of the pumping and cooling tower system, while reducing the efficiency of the chiller. While the most efficient flow rate (gallons per minute (GPM)/ton) cannot be generalized without a full evaluation … WebCalculate tons of cooling capacity Tons = BTU/hr. ÷ 12,000 Oversize the chiller by 20% Ideal Size in Tons = Tons x 1.2 If you follow these steps, you should have the ideal …
