In order to reduce the water consumption of natural draft wet cooling tower,this paper presented numer-ical investigations of the air-cooled condenser which would recycle evaporation loss of cooling towers.Based on governing equations of motion and vapor condensation,a numerical model was established,and the effects of cool-ing air velocity,geometric dimensions and materials of the air-cooled condenser on the performance characteristics of the air-cooled condenser were investigated.Numerical results reveal that water-saving amount per unit area in-creases with increase of cooling air velocity and condenser width,and it decreases with increase of the condenser length and height.Material property and thickness of condenser has no significant effect on the water-saving amount per unit area,and PVC material with light weight and low cost is recommended.
