A recent study published in the International Journal for Modern Trends in Science and Technology delves into the impact of moisture recovery systems on cooling tower performance. This research focuses on improving water recovery, a crucial aspect for industries that rely heavily on cooling towers for efficient heat dissipation.
Cooling towers play a vital role in various industrial processes, such as thermal power plants, die casting, and chiller plants. They operate on the principle of evaporative cooling, where a portion of the water evaporates, cooling the remaining water. While effective, this process results in significant water loss through the moist air expelled from the towers.
The primary aim of this study was to evaluate the effectiveness of a moisture recovery system in reducing water loss from cooling towers. The research compared the performance of cooling towers with and without this system, focusing on key parameters such as relative humidity (RH) and air velocity.

The study found that integrating a moisture recovery system significantly improved water recovery from cooling towers. The presence of a heater and sponge in the system led to a substantial reduction in moisture values. The heater enhanced the mixing of air and water, while the sponge effectively captured and condensed the water from the moist air. The combination of the heater and sponge resulted in a notable decrease in RH, indicating that the system can effectively reduce the amount of water lost to evaporation, thereby making the cooling process more efficient. The heater's role in improving air and water mixing was critical, as setups without the heater demonstrated less moisture recovery, highlighting its importance in the overall efficiency of the system. Comparative performance analysis showed that the system with both the heater and sponge consistently outperformed those without, in terms of reducing water loss and maintaining lower RH levels.
The research concluded that the proposed moisture recovery system effectively reduces water loss from cooling towers. This improvement not only conserves water but also enhances the overall efficiency of the cooling process. For large-scale applications, further refinements in system design are necessary to maximize efficiency.
Future Scope
Future research should focus on varying air velocity and water flow rates to further optimize the system's performance. Additionally, incorporating cooling pads could enhance moisture recovery, providing a more comprehensive solution to water conservation in industrial cooling towers.
This study underscores the potential of advanced moisture recovery systems in enhancing cooling tower efficiency, offering a promising solution to water conservation in industrial applications.
