The cooling tower is relatively high, and it is easy to form the smoke window effect (smoke window effect: indoor air rises or falls along the space with a vertical slope, causing the phenomenon of air convection to be strengthened. When the chimney Narrows, the airflow will accelerate). Because of the air pressure difference between the upper and lower, there will be wind from the bottom of the tower into the top of the tower. The hot water from the condenser is transported to the water distribution tank in the middle of the cooling tower, where the hot water is sprayed into a droplet shape. As the droplets fall, cold winds rise, cooling the hot water in the process. The rising water vapor from the upper mouth is the white mist we see. Cooling water drops to the sump and is re-transported to the condenser for recycling.
