Technical assistance: Replacing the fan in a circulating water cooling tower with a water turbine

As for the performance, it might not be that ideal; you can consult Jiangsu Zhongneng Photovoltaic Technology Development Co., Ltd. – it seems that the actual performance isn’t very good. You can find phones online.
It can achieve energy-saving effects, but the results may not necessarily be good
It is recommended to conduct thorough analysis before implementation; the performance of water turbines will certainly not be as good as before, although they are more energy-efficient. For specific implementation plans, relevant materials and design guidelines based on past experience can be used as references.
Agree with what was said on floor 4; the issue of energy conservation needs further verification.
Our factory has been modified; it saves energy significantly in low-temperature conditions, but we are concerned that the temperature won’t drop enough in high-temperature situations, so we need to conduct tests this summer. The manufacturer is Nanjing Xingfei.
Sir on the 6th floor, what is the size of the tower, and what is the diameter of the fan? As for the cost of the renovation, it’s estimated that it will amount to roughly the cost of electricity over a decade’s time, haha. Whether it’s worth it or not, we’ll see after the summer – let the facts speak for themselves.
Converting electrical energy into hydraulic energy, and then from hydraulic energy into mechanical energy, involves a conversion efficiency of less than 100% each time; this is certainly lower compared to converting electrical energy directly into mechanical energy for the fan. Therefore, when it comes to installing new towers, energy savings need to be further studied. As for upgrading existing towers, variable frequency technology is preferred due to its maturity and flexibility.
The view from the 9th floor is quite correct; in terms of transmission efficiency, turbines are lower. Moreover, it does not reduce the energy consumption of the water pump motors as they claim. Having said that, further consideration is still needed to determine whether it is true or false; it requires verification and proof based on facts.
According to the principle of energy conservation, it is electricity that ultimately drives the water turbine. Using water as the power source, the water pressure in the cooling tower must meet the requirements of the turbine, and this pressure is provided by the circulation pump. By setting the pressure control point of the circulating water pump lower, doesn’t that also save electricity? I am 80% opposed to this kind of modification.
Energy is certainly conserved; the energy that drives the turbine comes directly from the water pump motor. The head pressure required is by no means as simple as the so-called \"remaining head pressure\" as claimed, but is actually much higher than that value. This is why turbines cannot meet the requirements in certain engineering applications. It’s better to be cautious; I am 85% in favor of rejecting it.
