Bibliometric Insights Into Renewable Energy Powered Absorption Refrigeration Systems

Abstract

The contributions of this research paper is to illuminate the research of solar energy and its applications in cooling, focusing on its performance in real world applications. This also addresses the voids left over the existing literature of representing the COP and efficiency of ARS under non-ideal conditions. This research paper follows a hybrid PRISMA model and has also integrated case studies providing variance in geographical regions while adhering to its robust standards. Further review of existing literature reveals 3 major insufficiently studied limitations namely the sensitivity of system efficiency to solar irradiance volatility and biomass supply variability; the thermodynamic constraints imposed by ammonia as a refrigerant and its side effects such as high input temperatures resulting in corrosion over extended operation, and the supply chain disruption and economic barriers to entry along with technological limitations like low efficiency and COP. There is a need to improve these systems to function efficiently under high thermal stress while remaining economically viable. Thus a framework designed to optimize cooling technologies with limited resources and enhancement through  advanced thermal storage and automated controls is introduced. The study designs a road map for engineers and government officials to balance social equity, environmental resilience, and long-term expenses.
