Types of Cooling Towers: A Review

Abstract

Cooling towers are indispensable in dissipating heat from industrial processes and HVAC systems, hence playing a significant role in operational efficiency and sustainability. This review describes the classification of cooling towers based on airflow mechanisms, methods of heat transfer, and applications. This study highlights recent developments in hybrid cooling systems that combine wet and dry cooling technologies for improved water conservation and thermal efficiency. Through the analysis of recent developments in the domain, this work describes innovative design considerations that optimize thermal performances by including environmental concerns; designs that are in the counterflow and crossflow configuration. These insights underline continuous improvements within cooling tower technologies in light of evolving industrial and ecological demands.
