Questions about circulating water?
Thread Content
Dear sea friends, the temperature of the circulating water in our factory remains around 30 degrees after being cooled in the water tower. Is there any good way to reduce this temperature to 20-25 degrees? ? Please give your advice
1’ It depends on the amount of water you have. 2’ is mainly used in media at high temperatures; 3, to increase the circulation volume; 4, to enhance the capacity of the circulation tower
Why do you want to lower it to 25 degrees?
The reasons for the high temperature of the circulating water after cooling in the cooling tower are as follows: 1. The temperature of the circulating water entering the cooling tower is high, resulting in a high heat load. 2. The local temperature is too high. 3. The packing in the cooling tower is clogged, which affects the heat exchange efficiency of hot water within the tower. 4. The cooling tower fans are inefficient.
What was said upstairs is correct; to reduce the temperature, one needs to increase ventilation and decrease the density of water spraying.
You’re right:victory: :victory: :victory:
The outlet temperature at the upper water level is low, resulting in a fast cooling rate on the production line
Is there a more specific way? During the financial crisis, energy conservation and reduced consumption are being promoted! Try to solve the problem with as little spending as possible!
Check whether the filler is clogged; if it is, the temperature will definitely be affected. If the filler is not clogged, increase the airflow of the fan. First, check whether there is enough current available. If there is enough current, adjust the angle of the fan blades slightly. If there isn’t enough current, you can try adjusting the angle first. It’s okay for the motor to operate slightly above its rated power; if this helps, then replace the motor.
If the equipment is already operating properly and the packing tower is in good condition, then everything else is pointless; it is necessary to increase the water supply volume, the circulation rate of the circulating water, and improve the effective utilization rate of that water.

The solution is simple: add two more layers of perforated metal heat sinks at the drop height below the cooling tower. The principle behind this is to increase the time water spends in contact with air, thereby allowing its temperature to drop more quickly.
The theoretical cooling capacity of circulating water is related to the temperature and humidity of the surrounding environment; it must be determined based on the actual conditions in your area, as it cannot be achieved solely by relying on the equipment. If low-temperature water is truly necessary, a separate cryogenic system must be installed at the point of use.
Generally, there’s no need to lower the temperature of circulating water to 20-25 degrees; 30 degrees is already a good level. Could the original poster explain why it’s necessary to lower the temperature to 20-25 degrees? Also, with cooling processes like cooling towers, the temperature of the circulating water doesn’t drop below the atmospheric temperature, right? :lol :lol
Does your factory have a cooling station that can provide forced cooling?
It depends on the local temperature; if it’s too high, it’s difficult to lower it. The efficiency of a cooling tower is related to the wet-bulb temperature
The water temperature in the cooling tower depends mainly on the air volume supplied to it; with a constant air volume, efforts should be made to reduce the pressure of the return water
What the poster means is that it’s best to use existing equipment to achieve good results with as little **as possible: 1. If there is enough current available in your water pump, increase the outlet flow rate to boost circulation. 2. Check whether the nozzles in the cooling tower are clogged; this can be determined by seeing if the water flows evenly when poured from above. 3. If the packing in the cooling tower is clogged, clear it out. 4. Finally, there is the issue of poor performance of your fan: speed, blade angle, etc.
The lowest temperature of the cooling tower is the wet-bulb temperature of the local atmosphere, whereas in practice the actual lowest temperature is always 2-3 degrees higher than the wet-bulb temperature. If you are in the south, then in summer you will never reach 25 degrees. If a lower temperature is desired, a chiller is necessary, which will result in higher costs.
Winters in the north are quite cold, with temperatures dropping below -15 degrees Celsius, and at times even below -30 degrees. From a design perspective, in order to save energy, the water temperature can be reduced to 20 degrees Celsius during winter; this is feasible from a design standpoint. Of course, this cannot be maintained throughout the whole year – it needs to change according to different seasons. Adjustments may be necessary in terms of operation, which adds some complexity.

If that doesn’t work, then add another cooling tower.
