Abstract

Life without water is not possible on the earth, while modern humans need water not only for drinking, sanitization, and agriculture but also for industrial activities including electricity and cooling generations. 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 in improving environment sustainability by presenting various methods of energy and water modeling, 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– Number of Transfer Unit (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. This study’s practical outcome is proposing the methods of improving water sustainability for any cooling towers from past studies to assist engineers in the industry in modifying cooling towers water consumption. 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.
