The increasing energy needs of air conditioning systems in hot climates pose challenges concerning efficiency, operational expenses and environmental effects. The paper concentrates on creating and producing a modified split AC system that includes a phase change material (PCM) heat exchanger blended with aluminum oxide (Al2O3) nanoparticles. The objective is to improve the coefficient of performance (COP), lower energy usage, and increase cooling efficiency. Cylindrical PCM tubes integrated into the condenser side leverage latent heat storage for thermal buffering, while Al2O3 nanoparticles boost thermal conductivity, accelerating heat transfer cycles. The experimental findings indicate significant performance enhancements, including reduced compressor load, stabilized indoor temperatures, and extended equipment lifespan. These results highlight the promise of nano-enhanced PCM thermal storage systems in advancing energy-efficient and sustainable HVAC technologies.
Phase Change Materials (PCMs) are essential for increasing thermal energy storage and efficiency in air conditioning and building systems. Aidy et al. (2025) investigated the efficacy of fatty acid-derived PCMs enclosed in polylactic acid (PLA) for gypsum boards, enhancing passive cooling.
