Cooling Tower Performance

that lines of constant wet-bulb are parallel to lines of constant enthalpy, whereas lines of constant dry-bulb have no fixed relationship to enthalpy. Therefore wet-bulb temperature is the air parameter needed to properly size a cooling tower and its relationship to other parameters as shown in . Figure 3. Effects Cooling Tower Performance vs. Relative HumidityEffects of Relative Humidity Thermal Performance Cooling towers are rated most often using the inlet wet bulb temperature because these values are closely consistent with the enthalpy of the air. As the relative humidity changes along constant wet bulb lines, the enthalpy stays close to constant. This relationship is shown in Figure 1.Some results are removed in response to a notice of local law requirement.
