“…Consequently, when a hybrid setup met the cooling demand, the required power was significantly reduced by lowering the airflow to the dry section. Furthermore, the higher fractions of airflow going to the wet cooling tower followed with a more favorable COP [43].…”

“…Hybrid cooling towers can be used separately or simultaneously either for water conservation [39] or plume abatement [40][41][42] purposes. A hybrid cooling tower benefits depends on the heat load, the airflow rate, and the ambient air conditions [43]. The performance of hybrid cooling towers was investigated by experimenting parallel to numerical simulations on various operation conditions [43].…”

“…The outcomes revealed the most important factor in designing the hybrid cooling tower was water to air ratio was related to the operation condition of the cooling towers. A computational procedure to predict hybrid cooling tower performance in a wide and variable range of working conditions was developed [43]. The parallel airflow was flowing through both dry and wet sections while the cooling tower load water runs in a series path from the dry cooling tower to the wet cooling tower [44].…”

Life without water is not possible on the earth while modern humans need water not only for drinking, sanitization, and agriculture but also for industry, thermoelectric, and cooling plants. Hence, emphasis on water sustainability through different sectors including thermoelectric and cooling plants is an intelligent strategy while the tight connections of water and energy guide study towards energy-water nexus investigations. Cooling towers are equipment for dissipating the excess heat by water evaporation or they hidden gates for wasting water. The objective of the present study is to elaborate on the role of cooling towers, categorizing various methods for modifying water and energy consumptions through past studies, and mapping future studies regarding cooling towers. Presenting a history of energy-water modeling methods of cooling towers, the Markel, the Poppe, and the effectiveness–(NTU) models, has followed by assessing the environmental impact of cooling towers in the form of excess water consumption, plume, and energy usage. Summarizing and organizing the past efforts for upgrading water management in cooling towers have been in two directions either providing more water supply, or modifications of the cooling tower to use less water. Then the different methodologies for each direction are introduced for further elaborations. The practical outcome of this study is proposing the practical methods of improving water sustainability for any cooling towers from past studies to assist engineers in the industry for quick modifications of cooling towers. Showing the roadmap for the planning future investigations on the cooling towers based on the past efforts is another outcome of the present study to provide an insight for academia with research interest on cooling towers.
