    Cooling Tower: How to Enhance Energy Efficiency in Buildings

    Cooling Tower in Industrial Setting

    What is Cooling Tower in HVAC Systems

    A cooling tower is a specialized heat rejection device that extracts waste heat to the atmosphere through the cooling of a water stream to a lower temperature. It plays a crucial role in HVAC (Heating, Ventilation, and Air Conditioning) systems and industrial processes where large amounts of heat need to be dissipated efficiently.

    Cooling towers work on the principle of evaporation, where warm water from industrial processes or air conditioning systems is pumped to the top of the tower and distributed over the tower fill or packing. As this water cascades down through the fill material, it comes into contact with a stream of air moving upward through the tower. This air, usually induced by a fan, causes a small portion of the water to evaporate, which removes heat from the remaining water. The cooled water is then collected at the bottom of the tower and recirculated back into the system.

    Cooling towers are classified into various types based on their design and application, such as crossflow, counterflow, and hybrid configurations, each offering specific advantages in different industrial and HVAC settings.

    Basics of Cooling Tower

    A cooling tower is an essential component in HVAC and industrial processes for dissipating heat from water to the atmosphere.
