Design of circulating water
Thread Content
I would like to ask everyone: can I find information on the design of circulating water for cooling towers on this forum? Or please, experts, feel free to offer your advice. Thank you!
Hehe. . . . It’s listed in the design manual for whatever you need; you can check it there.
There’s no need for design work for something like this – it’s simply a waste of time. Tower manufacturers provide a complete set of materials to create a solution tailored to your needs, ensuring your satisfaction
Cooling tower manufacturers will design and manufacture the towers based on your usage requirements, usually in terms of the heat transfer capacity required. They will provide a complete set of materials. My company uses cooling tower manufacturers from Haimen, Nantong
Reply to 3# sisism: We want to expand our capacity, so we need to figure out how much headroom there is left for this
Reply to 5# Huanghe Zhi Shui Tian Lai: Generally, it involves counting the total number of process points that use recycled water, creating a list of them, and then selecting a few representative points to measure the flow rate of the recycled water as well as the temperatures of the water at the inlet and outlet. The energy changes associated with the recycled water at these points are calculated, and all such energy changes for the various points using recycled water are aggregated together. Considering that the temperature difference between the water entering and leaving a cooling tower is usually around 8–10 degrees, the actual required flow rate of recycled water can be determined by applying energy balance principles. It should be noted that the capacity of the cooling tower and the flow rate of the circulation pump need to be matched

Reply to 2# xuh7705: I checked the design manual, but found no information regarding the design calculations for cooling towers. I would like to know what criteria are used to determine the size of a cooling tower, as well as its capacity.
You can obtain the relevant information from manufacturers of cooling towers. Generally, cooling towers result in a small increase in the temperature of the water within the system cycle; they are designed with a temperature difference of 3–5°C, though this varies depending on whether it is a packed tower or an open tower
