Arrangement of dry air coolers and wet air coolers
Thread Content
Can dry air coolers and wet air coolers be installed together, and are there any spacing requirements?
Some of ours are on one platform, but there is about 15 meters between the dry and wet areas.
There is a distance of about 15 meters between the dry air coolers and the wet air coolers. What determines this distance?
It’s best to discuss this with the design institute.
The spacing between air coolers is recommended by the manufacturers of those coolers. Each type of air cooler requires a specific amount of clearance for intake and exhaust (in terms of space around it and in height), as well as consideration of the influence of surrounding buildings and wind direction. This is a very important factor; currently, in design work, people either design it directly or refer to various documents. While this approach can be used, it isn’t precise enough, and it can lead to issues related to forces acting on the system. Air coolers come in upper-intake and lower-intake types; if dry and wet types are placed too close to each other, they will affect one another and cause interference ； But there’s no need to worry; just ask the manufacturer casually
The main problem is as follows: 1. The air cooler is quite tall, while the evaporative cooling fan is shorter; there is a concern that the humid and hot air exiting the evaporative cooler might be drawn into the air cooler； 2. Generally, the wind speed between devices is considered to be below 2.5 m, so there will be no issue with hot air recirculation ；
They can be arranged together, with spacing requirements； The manufacturer’s products specify recommended requirements for the space available for air intake and exhaust; if this distance is too small, the air coolers interfere with each other, resulting in poor performance
