The open cooling tower uses the circulating water to spray on the packing of the cooling tower in a spraying manner. After the water contacts with air, heat exchange is achieved, and then the air flow in the tower is driven by the fan to circulate, and the hot air flow after heat exchange with water is brought out and then reaches the cooling target. The closed cooling tower uses the contact between water and the coil to take away the heat of the cooling medium in the coil through the heat transfer and exchange of the outer wall of the coil. The circulating water in the closed cooling tower only circulates inside the cooling tower, and the water supply pipe is properly replenished. Compared with the open cooling tower, the most prominent feature of the closed cooling tower is to increase the coil. The liquid working medium that needs to be cooled does not directly touch the water in the coil and exchanges heat through the pipe wall.
Characteristics of open cooling tower
The open cooling tower has the advantages of simple structure, low cost, convenient protection and maintenance, and is the most commonly used equipment in the early cooling equipment. However, because the fan motor and blades of the open cooling tower are exposed to the air, the noise during operation is relatively large. Because it is an open system, the cooling tower will drift water during operation, resulting in water loss. Water should be replenished frequently. Together, it will pollute the cooling water to a certain extent, causing its water quality to decline, and external debris will also enter the cooling water, resulting in water pollution; the cooling water pressure loss of the open cooling tower is higher than that of the closed cooling tower.
Advantages of closed cooling towers
The closed cooling tower is cooled by a fully enclosed circulation. Therefore, there is no phenomenon that debris enters the cooling pipeline system and then the pipeline is blocked. The closed cooling tower is cooled by soft water circulation and no scale is generated at high temperature, causing scaling of the cooling pipeline system. The closed cooling tower covers a small area, does not need to excavate a pool, is easy to locate, saves water and reduces energy consumption. The closed cooling tower adopts air-cooled evaporation and heat absorption dual cooling mode, with high cooling efficiency; can be directly cooling water, oil, alcohol, quenching liquid, brine and chemical liquid and other media, media without loss, composition is stable, due to the use of closed circulation, the medium is not affected by the environment, will not pollute the environment, which cooling water pressure loss is less than the open cooling tower.

Influence of different inlet and outlet water temperature on type selection of cooling tower
Different inlet and outlet water temperatures have a certain influence on the selection of cooling towers. A cooling tower is a device used to cool industrial processes. Its main function is to reduce the temperature of the system through the evaporation of water.
Factory must see: what is the cooling tower filler? And maintenance methods!
For the summer factory, there is a very important thing-cooling tower filler. It is mainly a material used in the cooling tower, when it comes to the cooling tower, it can also be understood as a cooling effect from the literal meaning. Today we will explore what is the cooling tower filler?
The water (hot water) that needs to be cooled is splashed into water droplets or a water film is formed to increase the contact area and time between water and air and promote the heat exchange between water and air. The cooling process of water is mainly carried out in the filling of water.
