Pingxiang Pingxiang Industrial counterflow cooling tower cooling tower cooling tower manufacturers Pingxiang Xin products have passed the national authoritative professional testing organization, the indicators better than national standards, cooling tower cooling tower Association has made the United States the international credibility of the (CTI ) certification, which represents the product quality and thermal performance of the cooling tower with Xin achieve world-class level, and has been the market's recognition and praise. Countercurrent tower: 1, the water in the tower packing, the water top-down, bottom-up air, the two opposite flows of cooling towers. 2, good thermal performance counterflow cooling towers, three cooling sections: ① water distributor to the top of the space filler, this segment of the higher temperature, so the heat to the air still. ② packing water and air heat exchange section. ③ filler to a sump space segment watering, water is cooled in this section referred to as "tail effect." In northern China water temperature can drop 1-2 ℃. In summary, the countercurrent tower than crossflow towers in the same situation, small size, about 20% filler, high tower countercurrent heat exchange process is more reasonable cooling efficiency. 3, clogging water distribution system, water spray to keep clean and not aging filler, little moisture reflux, frost and ice measures easier. Multiple designs can be combined winter temperature in the desired amount of water can be combined with a single operation or closed for all fans. 4, construction installation and maintenance easy, low-cost, commonly used in air conditioning and industrial large and medium-sized cooling circulating water. Work process Pingxiang round cooling tower as an example: through the pump room independent hot water at a certain pressure through pipes, cross throat, larynx song, the center will loop hydraulic hose into the cooling tower water system broadcast by sowing pipes holes on spraying water evenly on top of the filler; Han air dry low value in the role of fan air into the tower from the bottom of the net, forming a film of water and air when the water flows through the heat exchange surface of the filler hot air and high humidity Han extract value from the top of the cooling water droplets into the bottom of the basin, the outlet flow into the host. Under normal circumstances, into the tower air dry bulb temperature of the air humidity, there is a clear difference in the concentration of water molecules and the kinetic energy of the pressure difference, when the fan is running, in the role of the tower between the static pressure of water and air, water molecules evaporate into the air constantly, becomes water vapor molecules, the remainder of the average kinetic energy of water molecules will be reduced, so that the circulating water temperature drop. As can be seen from the above analysis, evaporative cooling and air temperature (dry-bulb temperature is generally said) irrespective of the water temperature below or above, as long as water molecules can evaporate into the air continuously, the water temperature is reduced. However, water does not go on endlessly evaporation into the air. When the air in contact with the water-unsaturated, water molecules continue to evaporate into the air, but when the air reaches water vapor saturation of the contact surface, the water molecules evaporate does not go out, but in a dynamic equilibrium state. The evaporated quantity of water molecules from the air return is equal to the number of water molecules of the water, the water temperature remains constant. It can be seen, the air in contact with water and dried, and evaporated more easily, it is easy to reduce the water temperature.
