"Cooling tower" means a device that cools water. The water exchanges heat and mass with the air flowing through it, causing the water temperature to drop.
An open cooling tower is a device that uses the contact of water and air to dissipate waste heat generated in industry or refrigeration and air conditioning through evaporation. The basic principle is: after the dry (low enthalpy) air is pumped by the fan, it enters the cooling tower from the air inlet network; high temperature water molecules with high saturated steam partial pressure flow to the air with low pressure, moist heat (high enthalpy) The water is sprinkled into the tower from the water seeding system. When the water droplets are in 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 the pressure, that is, through the contact with the unsaturated dry air. The heat transfer takes away the sensible heat of the water, and part of the water evaporates to take away the latent heat in the water, so as to achieve the purpose of cooling the cooling water.
The closed cooling tower uses the contact between water and the coil, and the heat of the cooling medium in the coil is taken away by the heat transfer belt of the tube wall to achieve the purpose of cooling. The circulating water in the closed cooling tower only circulates inside the cooling tower to exchange heat with the air for cooling, and then contact the coil to take away the heat of the working medium in the coil. The obvious feature is the addition of coils. The liquid working medium that needs to be cooled flows in the steel coil without direct contact with water, and exchanges heat through the tube wall.
