Cooling tower splash net packing

The importance of choosing cooling tower packing: Considering that the principles of cooling tower design are based on the contact surface between water and air, therefore, the surfaces that put water in contact with air in terms of heat transfer are important. Choosing the type and type of packing media is not an easy process because this choice is highly sensitive for many reasons and this is because the failure of this part means the loss of the efficiency of the entire system. Choosing the material and type of packing and even the steps of packing and dimensions of packing is one of the duties of cooling tower designers. This choice is based on different parameters, the important reasons of which are briefly as follows: 1- The temperature of the hot water entering the cooling tower (because each type of packing has a different temperature tolerance) 2- thermal efficiency 3- Acidity or alkalinity of water or any other fluid 4- Hardness of circulating water More information on Azin's website https://www.azintahvie.com/ Therefore, according to the characteristics of the used environment and the analysis of the circulating fluid, as well as the temperature range of this fluid, it can be designed by considering the highest thermal efficiency, the highest useful life, and the highest specific level of the type and material of the packing used. Types of packing: A) film or cascade (film) b) Splash (it includes several different models such as: random splash and block splash, etc.) Cascading packings: Cascade packings are divided into two categories according to their type: 1- PVC 2- PP Compared to the PP model, PVC packings have a series of advantages and a series of shortcomings, including the advantages of this type of packing compared to the PP model in its higher specific surface. (The effective surface of heat transfer plates or sheets is called specific surface per unit volume) Now, according to the pitch of PVC packings, from 12 mils to 19 mils, the specific surface of these packings is from 70 to 300 square meters per cubic meter. It is variable. (The packing pitch is the distance between the pages inside the packing) Therefore, the lower the packing step, the higher the specific heat transfer surface and the more heat transfer plates can be collected in a certain volume, but this step should not be lower than a certain limit in terms of blockage between the plates, because after some time, the transfer plates The heat will be blocked and the tower will not have the required efficiency. Meanwhile, in most projects, the limitation of the cooling tower space is a fundamental factor in the design, so the designers are looking for the implementation of packings with a higher special level by considering other parameters.
