Design and Optimization of a Solar-Powered Hybrid Cooling System for Sustainable Buildings

Project Abstract

The increasing demand for energy-efficient and environmentally sustainable cooling solutions in buildings has prompted extensive research into renewable energy-powered systems, particularly solar-based technologies. This study aims at designing and optimizing a hybrid cooling system that integrates solar thermal and photovoltaic energy sources to enhance thermal comfort in buildings while minimizing energy consumption and greenhouse gas emissions. The research begins with an extensive review of current cooling technologies, focusing on hybrid systems that combine solar thermal and photovoltaic mechanisms, their efficiencies, cost-effectiveness, and integration challenges. The core objective is to develop a system that not only harnesses solar energy efficiently but is also adaptable to various building types and climates, thereby offering a sustainable alternative to conventional air conditioning systems. The methodology employs a multidisciplinary approach, combining thermodynamic modeling, system simulation, and experimental validation. Initially, detailed energy analysis and load assessment are conducted for different building typologies to determine the cooling requirements. Subsequently, a conceptual design of a hybrid system comprising solar collectors, absorption chillers, photovoltaic panels, and thermal storage is proposed. The system’s components are modeled using software tools such as TRNSYS and MATLAB to simulate performance under different operational scenarios. An optimization algorithm employs genetic algorithms to fine-tune key parameters, including collector tilt angles, storage capacity, and system controls, aiming to maximize energy efficiency and cost savings. The experimental phase involves constructing a scaled prototype setup within a controlled environment to validate the simulation results and assess real-world performance metrics. Data collected include solar insolation, system output power, cooling capacity, and operational efficiency over different weather conditions and operational periods. Results reveal that the optimized hybrid system significantly outperforms standalone solar or conventional cooling systems in terms of energy consumption, CO2 emissions reduction, and economic viability. Sensitivity analysis further elucidates the impact of varying climatic conditions, system configurations, and operational strategies. The findings demonstrate that an integrated hybrid approach effectively leverages solar energy for cooling applications, reducing reliance on grid electricity and fossil fuels. The study underscores the importance of optimal design parameters and control strategies in maximizing system efficiency, suggesting that widespread adoption could substantially contribute to sustainable building practices. The research concludes with recommendations for practical implementation, potential challenges, and avenues for future research, emphasizing the importance of integrating renewable energy solutions into building infrastructure to promote environmental sustainability and energy independence. Overall, this project provides a comprehensive framework for developing cost-effective, scalable, and sustainable cooling systems that align with global energy conservation goals.
