Closed cooling tower (also called evaporative air cooler) will put the tower tube heat exchanger, through the air, spraying water and recycled water heat exchange to ensure that the flow of the cooling effect. Because it is a closed loop, which can ensure the water quality from pollution, well protected and efficient operation of the main equipment to improve the service life. When the outside temperature is low cooling towers, water spray system can be stopped, play water-saving effect. Push increasingly scarce national energy conservation policy implementation and water resources, in recent years, closed cooling tower in steel metallurgy, power electronics, machining, air conditioning systems and other industries has been widely used. Northern winter temperatures often below freezing, run antifreeze issue closed cooling tower cooling towers have become increasingly prominent brand, If the solution is not good, it may be damaged by frost tubes or other parts of the cooling tower. Depending on the process characteristics, closed cooling tower and some winter day run plant cooling tower, and some part of the time period to run, some almost not. But they need to consider the freezing problem. If the closed cooling tower in the winter need to run, stop, and internal circulation shall spray water water emptying. Structural features: 1. the use of cold and heat exchanger coil packing heat collaborative structure cooling Tavi repair, good cooling efficiency, small size. 2. inlet located at the inlet louvers, avoid direct sunlight into the tower, algae breeding, spraying water clean. 3. The use of T2 copper tubes, the design pressure 1.6Mpa, keep fluid from contamination. 4. The heat exchanger coil modular design. 5. The use of aluminum axial fan, outlet velocity quickly, avoid hot air reflow, low operating noise.
