cooling tower

A cooling tower is a structure designed to remove heat from a system, typically used in industrial processes, power plants, and HVAC systems. It dissipates excess heat from water-cooled systems by transferring the heat from the water to the air.

Key Features of Cooling Towers:

Heat Dissipation:

The primary function is to expel heat from hot water through evaporation, cooling the water before it is returned to the system.

Types of Cooling Towers:

Wet Cooling Towers: Use water evaporation to cool the system. Most common in industrial applications.

Dry Cooling Towers: Use air alone (without water evaporation) to cool, typically found in dry climates or where water conservation is a priority.

Hybrid Cooling Towers: Combine both wet and dry cooling methods to optimize efficiency in varying conditions.

Components:

Fill Media: Increases the surface area for heat exchange and improves the cooling process.

Drift Eliminators: Remove water droplets from the airflow to prevent water loss and drift.

Fans: Circulate air through the tower to aid in heat dissipation.

Water Basin: Collects the cooled water, which is then pumped back into the system.

Operation:

Hot water from an industrial process or HVAC system is pumped into the cooling tower, where it is exposed to air. The water loses heat via evaporation, and the cooled water is returned to the system.
