How The Open Cooling Tower Works
Jan 03, 2019

An open cooling tower is a device that utilizes the contact of water and air to dissipate waste heat generated in an industrial or refrigeration air conditioner by evaporation.

The basic principle is that the dry (low enthalpy) air enters the cooling tower from the air inlet net after being twitched by the fan; the high temperature water molecules with large pressure of saturated steam flow to the air with low pressure, and the heat is high (high enthalpy) The water is sprinkled into the tower. When the water droplets come into contact with the air, on the one hand, due to the direct heat transfer between the air and the water, on the other hand, due to the pressure difference between the surface of the water vapor and the air, evaporation occurs under the action of pressure, that is, through the unsaturated air with unsaturated air. The heat transfer takes the sensible heat of the water, and part of the water evaporates to remove the submerged zone in the water, thereby achieving the purpose of cooling the cooling water.
