Questions regarding air coolers and composite air coolers
Thread Content
For the company’s new projects, after considering various factors, we plan to use air coolers or combined air coolers instead of circulating water cooling. There are several questions I would like to ask you: 1. What are the advantages and disadvantages of combined air coolers compared to ordinary air coolers? 2. What are the advantages and disadvantages of air coolers/composite air coolers compared to circulating water? It’s mainly a composite air cooler; those who are familiar with it could please explain it in detail. Thank you.
The advantages and disadvantages of air cooling and water cooling have been a subject of ongoing debate in academic circles. Air-cooled systems require many consumables, are large in size, have low efficiency, high power consumption, and high operating costs. However, it can make use of free air, save precious water resources, and is easy to repair, replace, and clean. Water-cooled systems require fewer consumables, are compact, highly efficient, and do not require electricity. However, the indirect costs such as the operation of water tower fans, as well as the installation and maintenance of pumps and pipelines, are also significant; in particular, the costs associated with maintaining water quality (through the addition of chemicals) are considerable. The elegance of water also comes at a significant cost. Currently, the drift rate of water is generally calculated at around 3%. In other words, 100 tons of water become 97 tons after being cooled by a cooling tower. The cooling tower has a high volume of air intake, which enables extensive contact between water and air within the packing to lower the water temperature; it also absorbs impurity ions (Ca, Mg, Na, Cl) from the air into the water. The water tower acts like a collector, increasing the concentrations of Ca, Mg, Na, and Cl ions in the water, thereby forming soluble salts that enter the circulation system. As temperature and flow rate change, overflow and sediment adhere to the inner wall of the pipeline. It increases the system’s resistance and corrosion, as well as reduces heat transfer efficiency. Composite air cooling combines the advantages of air cooling and water cooling, saving water and electricity and reducing operating costs.

Compound air coolers are mainly energy-efficient, require little space, their modular structure facilitates maintenance, and they have a low water loss rate
Compound air cooling is not recommended, as its heat exchange efficiency is poor. Over time, the temperature of the desalinated water in the circulation system becomes similar to that of the medium itself, which reduces the heat exchange efficiency; unless the desalinated water circulation system is modified, it will not work well. Air cooling is generally installed at the top of the pipe rack, and it doesn’t take up much space. Air cooling requires less investment and still yields good results.
I would like to ask: as far as I understand, a combined air cooler is a structure that combines a wet air cooler with an evaporative cooler. I’m not sure if this is correct!
Yes, it’s in that format.
The composite air cooler as I understand it is dry air cooling + evaporative air cooling
It mainly depends on the inlet and outlet temperatures of the medium
