Cooling towers are commonly used for what purpose?

• A. To heat water in winter
• B. To cool water in chillers
• C. To filter water impurities
• D. To increase water pressure in systems

Answer: (B)

Cooling towers are primarily used to cool water that is circulated through chillers, which in turn are often part of larger heating, ventilation, and air conditioning (HVAC) systems. The process involves removing heat from the water that has absorbed heat from the building or equipment and then dissipating that heat to the atmosphere. In essence, when water heats up as it absorbs thermal energy from other processes, it is then directed to the cooling tower. Here, the water is exposed to air and, through evaporation, a portion of the water converts to vapor, thereby reducing the water temperature. The cooled water can then return to the chillers to continue the cycle of heat exchange, making the system efficient for maintaining comfortable indoor temperatures. This process is crucial in large buildings where cooling demand is significant, and ensuring that this system operates effectively is vital for energy efficiency and preventing conditions conducive to Legionella growth, which is a key consideration within the context of plumbing systems and public health.
