Transfer models were developed with overall wetting condition and part overall wetting and some water droplets larding in air condition. The relative errors of efficiency prediction are small than 2 percent because Lewis factor is equal to 1.The method to determine the mean saturated line slope of moist air was presented, which can apply to hot water and air. The wall wetting rate has remarkable effect on cooling efficiency. But water droplets in air effects are small and can be ignored in engineering calculations.
