How do the cooling towers of industrial air conditioners evaporate heat?
There are three heat dissipation methods for cooling towers, namely contact heat dissipation, evaporation heat dissipation and radiation heat dissipation. Today, it is mainly about the evaporation and heat dissipation principle of cooling towers. First of all, let's first understand how the cooling towers of industrial air conditioners dissipate heat?
In a wet cooling tower, the temperature of hot water is high, and the temperature of the air flowing over the surface of the water is low. The water transfers heat to the air, is carried away by the air, and dissipates into the atmosphere. The cooling tower mainly relies on evaporation and contact to dissipate heat. Two heat dissipation methods, the radiation heat dissipation is very small, can not be ignored.
Evaporative heat dissipation principle of cooling tower
Evaporation and heat dissipation are accomplished through material exchange, that is, through the continuous diffusion of water molecules into the air. Water molecules have different energies. The average energy is determined by the water temperature. Some water molecules with high kinetic energy near the water surface overcome the attraction of neighboring water molecules and escape the water surface and become water vapor. As the water molecules with high energy escape, the water near the water surface The energy becomes smaller. Therefore, the water temperature decreases, which is evaporative heat dissipation.
It is generally believed that the evaporated water molecules first form a thin layer of saturated air on the water surface, the temperature of which is the same as that of the water surface, and then the speed of water vapor diffusion from the saturated layer to the atmosphere depends on the water vapor pressure of the saturated layer and the water in the atmosphere. The difference in vapor pressure is Dolton's law.
The above is the evaporative heat dissipation method of the cooling tower.
