To reduce the size of the tower
To increase the temperature of the water
What is the role of pumps in cooling towers?
Pumps increase the temperature of the water in the cooling tower.
Pumps are used to filter impurities from the water in the cooling tower.
Pumps circulate water to transfer heat from the system to the cooling tower.
Pumps store excess water for future use in the cooling tower.
How do cooling towers help save energy?
Cooling towers save energy by lowering the temperature of water, reducing the energy needed for cooling systems.
Cooling towers increase the temperature of water, making cooling systems work harder.
Cooling towers are used to heat water for industrial processes.
