The main principle of the closed cooling tower is that the spray water is evaporated on the outer wall of the coil to cool the fluid in the tube, and the fan is used to take away the generated water vapor in time. A small part of the spray water evaporates, and the rest is collected and circulated by the chassis. In addition to being used in air conditioning systems, it can also be used in metallurgy, chemical, and petroleum industries. But its use also increases manufacturing investment and operating costs. Therefore, optimization design is needed to achieve the purpose of economical energy saving. Its main component is a tube evaporative cooler, and its structural parameters have an important influence on the optimal design of the closed cooling tower. Therefore, the optimization of its structure focuses on the optimization of the tube evaporative cooler.

1.Optimization of objective function structure

Through the cooperation of different cooling components, its operating efficiency is reduced.

2.Coolant optimization

Different coolants have an important decisive effect on its cooling.

3.Working environment of closed cooling tower (environmental optimization)

Installing it in a ventilated environment can increase operating efficiency and facilitate air circulation in the tower.
