Selection and calculation issues for cooling towers
Thread Content
I would like to ask: given that the circulating water flow rate is 5000 m3/h, and considering site constraints, two cooling towers with a capacity of 2500 m3/h each should be used. What diameter fan needs to be chosen? The filler is a regular sine wave.
To determine the appropriate diameter for the fan, check the manufacturer’s sample models
This depends on your calculation parameters, such as the wet-bulb temperature of the air where you are located, the temperature difference gradient required, the range of variations in the volume of circulating water, the intensity of changes in the circulating water, and the configuration of the cooling fans (single fan, dual fans, or multiple fans)
Based on the designed water flow rate of the cooling tower, the design inlet and outlet water temperatures are determined. Meanwhile, the thermal and resistance formulas for the packing are obtained from the packing manufacturer. Appropriate design dry and wet bulb temperatures are selected considering local meteorological conditions to calculate the heat load; this allows for the determination of the theoretical air volume and pressure required for cooling. On this basis, a fan is chosen (with fan specifications provided by the fan manufacturer)
