　　The circulating water in a counter current closed cooling tower only circulates inside the tower, exchanges heat with air for cooling, and then comes into contact with the coils to take away the heat of the working fluid inside the coils. The water replenishment pipe is appropriately replenished. Compared with an open cooling tower, the most obvious feature of a closed tower is the addition of coils. The liquid working fluid that needs to be cooled flows inside the steel coils without direct contact with water, and exchanges heat through the tube walls.UFlCooling tower noise reduction treatment manufacturer

　　Open cooling tower is a device that utilizes the contact between water and air to dissipate waste heat generated in industry or refrigeration and air conditioning through evaporation. The basic principle is that dry (low enthalpy) air is drawn by a fan and enters the cooling tower through the air inlet network; High temperature water molecules with high partial pressure of saturated steam flow towards low-pressure air, while hot and humid (high enthalpy) water is sprayed into the tower by the self seeding water system. When water droplets come into contact with air, on the one hand, due to the direct heat transfer between air and water, and on the other hand, due to the pressure difference between the surface of water vapor and air, evaporation occurs under the action of pressure. That is, the sensible heat of water is carried away by heat transfer with unsaturated dry air, and some of the latent heat in water is taken away by water evaporation, thus achieving the goal of cooling the cooling water.UFlCooling tower noise reduction treatment manufacturer

　　A closed cooling tower utilizes the contact between water and coils to transfer heat through the tube wall and heat to the cooling medium inside the coils, achieving the cooling goal. The circulating water in a closed cooling tower only circulates inside the tower, exchanges heat with air for cooling, and then comes into contact with the coils to take away the heat of the working fluid inside the coils. The water replenishment pipe is appropriately replenished. Compared with an open cooling tower, the most obvious feature of a closed cooling tower is the addition of coils.

　　1. The cooling principle of the open cooling tower is to spray hot water on the glass fiber filler in the form of spray to achieve heat exchange through the contact between water and air, and then a fan drives the flow of air in the tower to bring out the hot air after heat exchange with water, so as to achieve cooling. This cooling method requires less initial investment, but has higher operating costs (water and electricity consumption).UFlCooling tower noise reduction treatment manufacturer

　　2. The cooling principle of a counter current closed cooling tower is, in simple terms, two stages: an internal circulation and an external circulation. There is no packing, the main part is the copper tube surface cooler. ① Internal circulation: Connect with the target device to form a closed circulation system (with soft water as the circulating medium). Cooling the target device by transferring the heat from the target device to the cooling unit. ② External circulation: In the cooling tower, it cools down the cooling tower itself. Not in contact with the internal circulating water phase, only through the copper tube surface cooler in the cooling tower for heat exchange and dissipation. Under this cooling method, the operation of the motor is set according to the water temperature through automatic control.UFlCooling tower noise reduction treatment manufacturer
