What are the types of common cooling towers

1. Counterflow cooling tower
1. The water is in the packing in the tower, the water is from top to bottom, the air is from bottom to top, and the two flow in opposite directions. A cooling tower
2. The counter-current cooling tower has good thermal performance and is divided into three cooling sections:
① From the water distributor to the top of the filler, the water temperature in this section is relatively high, so the heat can still be transferred to the air.
② Filling water and air heat exchange section.
③ The cooling tower fills to the water spraying section of the sump space, and the water is cooled in this section, which is called "tail effect". In northern my country, the water temperature can drop by 1-2°C. To sum up, the counter-current tower is about 20% smaller in packing volume than the cross-flow tower under the same conditions, and the heat exchange process of the counter-current tower is more reasonable and high in cooling efficiency.
3. The water distribution system is not easy to block, the water filling is kept clean and not easy to age, the moisture backflow is small, and the anti-freezing and deicing measures are easier. Multiple units can be combined in design. In winter, the required water temperature and water volume can be combined with a single unit or all fans can be turned off.
4. Easy construction, installation and maintenance, low cost, commonly used in air conditioners and industrial large and medium cooling circulating water.
