Application principle of closed cooling tower;
Closed cooling tower adopts two-stage cooling method, namely, the first-stage cooling adopts air cooling, the cooler coil adopts air cooling; the secondary cooling adopts air-cooled spray. When the ambient temperature is relatively high, secondary cooling is used. At the same time of air cooling, the spray system sprays water onto the surface of the cooler, which can take away the heat of the coil when the water evaporates, so as to achieve the cooling effect.
Advantages of closed cooling tower:
1. The circulating cooling medium is closed in circulation, no impurities enter, ensuring the purity of the medium;
2, the circulating water adopts soft water, which will not scale and block the pipeline;
3, small footprint, can be moved and placed as needed;
4. Low energy consumption and simple operation.
The advantages and main configuration of closed cooling tower design:
1. Anti-freezing and anti-scaling heat exchanger-all closed cooling towers with perfect performance adopt improved high-efficiency heat exchangers. The heat exchange coil is optimized on the traditional basis, which can effectively reduce the air side resistance and is more suitable for larger spray water volume. As the distance between the tubes increases, the number of heat exchange tubes per unit volume increases, the heat exchange area increases, and the heat exchange efficiency increases significantly. The working fluid flowing downward in the tube and the air flowing upward outside the tube have the best heat exchange effect. The entire heat exchanger is composed of one or more coil units, surrounded by a steel frame box, which is sturdy and durable. The coil assembly is made of 0.6mm T2 deacidified red copper tube and welded with silver electrode. All the copper tubes are appropriately inclined along the flow direction of the working fluid in the tube to facilitate the flow of the working fluid. The dedicated low-level water tank is convenient for coil drainage and recycling. Equipped with automatic drainage and air intake system to achieve anti-freezing effect. The special low-power and large-flow spray water pump can completely wet the outer wall of the pipeline to avoid the formation of scale at the junction of dry and wet points. The special air intake system can isolate the combination of particle dust and calcium and magnesium ions in the air to achieve the anti-scaling effect. They are all very well manufactured and must pass the 2.5 MPa withstand voltage test before they can leave the factory.
2. Tower structure-the stable and durable closed cooling tower has been carefully designed by our professional designer team, and its performance, appearance, and configuration have reached the domestic leading level. In terms of performance and price, Yunuo Refrigeration is your preferred cooperative enterprise!
3, transmission device-reliable operation of the fan adopts three-proof aluminum alloy, low noise, large air volume, stable operation. Perform balance calibration before leaving the factory to ensure its stability.
