Coupled Evaporative and Desiccant Cooling Systems for Tropical Climate

Abstract: The major consumer of energy in buildings is the Heating, Ventilation, and Air-Conditioning (HVAC) system, which is tightly linked to local climatic conditions. The utilization of HVAC requires improvements to its passive cooling strategies due to its high energy consumption. This article tries to attract the researchers’ attention on utilizing the coupled evaporative and desiccant cooling systems in a tropical climate and their required sustainable improvements. Meanwhile, the emphasis on utilizing certain materials for evaporative cooling applications has been made. This review indicated that the multiple green materials such as agricultural and industrial waste and geopolymers are effective as a dehumidifier replacing chemical desiccant in desiccant based evaporative cooling systems.
