Comparative Analysis of Dew Point Evaporative Cooling with and without Solar Power Integration

Abstract

The objective of this study is to examine the operational efficiency of a heat exchanger system when subjected to different dry bulb temperatures of incoming air. Additionally, the study aims to compare the system performance when solar power is integrated for the blower and pump, as opposed to operating without solar power integration. The main aim of this study is to evaluate the influence of renewable energy sources on the efficiency of the system. The experimental findings demonstrate that the efficiency of systems incorporating solar power integration differs by a maximum of 9% when compared to systems without solar power integration, while operating under identical conditions. Moreover, these variations have discernible impacts on wet bulb temperatures and dew points, albeit in a nuanced manner. The incorporation of solar energy into a system has a negligible impact on the relative humidity of the air that is discharged from the heat exchanger. The deployment of solar electricity, meanwhile, offers benefits in terms of sustainability, cost savings, and environmental friendliness. The findings underscore the potential advantages of using solar energy into heat exchange systems, with a particular focus on enhancing performance, reducing costs, and promoting environmental sustainability.
