Abstract

This study investigates the optimization of energy-saving strategies in residential air conditioning systems utilizing R410A refrigerant, operated with R32 as an alternative. With increasing concerns regarding environmental impact and energy consumption, finding efficient solutions becomes imperative. The research explores various approaches, including system design modifications, operational adjustments, and technology integration, to enhance energy efficiency while maintaining optimal cooling performance. Through a combination of theoretical modeling, simulation studies, and empirical data analysis, this research identifies key factors influencing energy consumption in residential air conditioning systems and proposes innovative strategies for optimization. Furthermore, the study incorporates a comprehensive test rig and thermal control room setup to conduct real-world experiments. This infrastructure facilitates the evaluation of proposed energy-saving strategies under controlled conditions, allowing for accurate measurement and validation of performance metrics. The integration of a test rig and thermal control room enhances the reliability and applicability of the research findings, ensuring their relevance to practical implementation in residential air conditioning systems. Overall, the findings of this research contribute to advancing sustainable cooling technologies, offering practical insights for policymakers, manufacturers, and heating, ventilation and air conditioning professionals to mitigate environmental impact and promote energy conservation in residential air conditioning applications.
