Jiangsu Yunuo Cooling Technology introduced to us what the cooling power of the closed cooling tower is related to.
The service life of each type of equipment is limited, and the closed cooling tower is no exception, but it should be completed on the basis of proper maintenance, otherwise its cooling performance may also be affected. Now that the cooling power has been mentioned, it is necessary to understand its determining factors. In addition to maintenance, what else will affect the cooling power of the closed cooling tower.
The first thing that comes to mind is the amount of spray water, but when the amount of water is reduced, the heat dissipation of the equipment will also be reduced. After a similar phenomenon occurs, it is necessary to check whether the supply pressure of the pump is stable; whether there is an air phenomenon; whether there is a blockage, etc. At the same time, the fan and air volume are also one of the factors that determine the cooling power, so they are also the key to inspection.
Closed cooling towers Under normal conditions, closed cooling towers need to be installed in a ventilated place, which shows the importance of the environment to it. Therefore, try to prevent some constructive operations around the cooling tower after installation, which will affect the ventilation environment of the cooling tower. . In addition, the scale and the spray system must also have an impact, so it is necessary to prevent the generation of scale and ensure the normal operation of the spray system. The water distribution system is not easy to block, the water filling is kept clean and not easy to age, the moisture backflow is small, and the method of preventing freezing and deicing is simpler. Multiple units can be designed in combination. In winter, the required water temperature and water volume can be combined with a single unit to operate or all fans can be turned off.
The maintenance of the construction device is simple and the cost is low, and it is commonly used in air conditioners and industrial large and medium-sized cooling circulating water. Cross-flow tower, the water is filled in the tower, the water flows from top to bottom, and the air flows horizontally from the outside of the tower to the inside of the tower. The two flow directions are vertical and orthogonal to a cooling tower. Commonly used in residential areas with strict noise requirements, it is a cooling cycle tower that is widely used in the air-conditioning industry. Advantages: energy saving, low water pressure, small wind resistance, also equipped with low-speed motor, no dripping noise and wind noise, easy maintenance of filling and water distribution system. Multiple cooling towers can be constructed and placed at will according to the building shape, and single or multiple cooling towers can be activated according to the required water temperature. It should be noted that the frame needs 40% more heat exchange to have more filler volume, the filler is easy to age, the water distribution hole is easy to block, the anti-icing is not good, and the moisture backflow is large. The advantage of a cross-flow tower is the disadvantage of a counter-flow tower.
For the spray-ventilated cooling tower without packing, the common spray nozzle is installed at the air inlet at the bottom of the closed cooling tower. When the hot water passes through the inner swirling vane of the nozzle, the inner swirling flow is formed to form a fine atomization and sprayed out, so that the mist exists, and it is sprayed upwards and flows downwards. The atomization is uniform without hollowing phenomenon, the cooling effect is stable, the power consumption is low, the water drift rate is 0.01%, no filler, the cost is low, and the service life is long, which conforms to the GB7190.1-1997 standard. Application range of metallurgy, food, chemical industry, high turbidity, high temperature, anti-corrosion cooling tower.
