Calculation of cooling capacity for cooling towers
Thread Content
I have been researching cooling towers recently. The formula for the cooling capacity in GB/T50392-2016 is this one, but in other sources I’ve consulted, the formula for cooling capacity is different; specifically, it involves the numerator inside the parentheses. In the standard, it is expressed as h1 – h2, while in another approach it is Δi = h1 – h1. Are these two expressions the same? Or is one of them incorrect?
h2 is the enthalpy of the air leaving the tower, while h1 is the enthalpy of the air entering the tower. The Simpson’s rule for numerical integration utilizes the differences between the saturated enthalpy of the air leaving the tower at various temperature points and its actual enthalpy.
MARK it; check it again if it’s useful
