A theoretical analysis of crossflow cooling tower was studied under conditions such that the change in the water flow rate due to vaporization is not negligible throughout the apparatus and a method of numerical calculation to estimate both the enthalpy of air and temperature of water in a tower was derived, and by applying this method, a calculation method of overall volumetric enthalpy transfer coefficients and the effect of operating conditions on the enthalpy arrival factor, which expresses the cooling effect, were investigated. In addition, the deviation in the tower volume between the case of taking into account and not taking into account the change in the water flow rate in crossflow cooling towers was discussed under the same operating conditions.
