I. Working Principle

Dry-wet combined closed circuit cooling towers, also known as dry-wet closed circuit cooling towers, differ from conventional closed circuit cooling towers. They are divided into two sections: one for dry cooling, similar to an air cooler, where high-speed air passes over finned heat exchangers to cool down the high-temperature medium inside the tubes. The other section is the same as a conventional counterflow closed circuit cooling tower, with spray water being sprinkled from above and cool air entering from below, carrying away the evaporated moist air outside the tower.

Section II: Process of Operation

1. The production process equipment generates heat, which is transferred to the circulating medium, high-temperature medium, and then enters the dry-wet combined closed cooling tower through sealed pipes.

2. High-temperature medium enters the dry cooling coil, transferring heat through the base pipe to the fins, where it exchanges heat with the high-speed airflow passing over, carrying away heat energy and reducing the temperature.

3. After cooling, the medium enters a wet coil where the spray water evaporates and condenses, absorbing heat to continue cooling. The temperature drop is greater than that in a dry coil, but it requires the use of spray water.

4. The circulating medium is cooled and temperature reduced through dry and wet coil cooling to meet process requirements, then it is sealed and returned to the production equipment for reheating, and the cycle repeats.
