A Comprehensive Review on Enhancing Refrigeration System Efficiency Using Nanoparticle-Enhanced Refrigerants and Phase Change Materials in Condenser Applications"
Year: 2025
Type: article
Abstract: Improving the energy efficiency of refrigeration systems has become increasingly important due to rising global energy demands and heightened environmental concerns. Conventional refrigeration systems often suffer from high energy consumption and inefficient heat transfer, especially within the condenser unit. In recent years, significant research efforts have focused on incorporating advanced materials and technologies to enhance thermal performance and reduce energy losses. This review critically examines two promising approaches: nanoparticle-enhanced refrigerants (nano-refrigerants) and phase change materials (PCMs). Nano-refrigerants are created by dispersing high-thermal-conductivity nanoparticles into traditional refrigerants, resulting in improved heat transfer capabilities and system performance. These modified fluids help increase the coefficient of performance (COP), reduce compressor work, and enhance overall heat exchange efficiency. On the other hand, PCMs are used in condensers for thermal energy storage by absorbing and releasing latent heat during phase transitions, helping to stabilize temperature fluctuations and manage peak thermal loads. The combined application of nano-refrigerants and PCMs in refrigeration condensers offers a synergistic advantage by enhancing heat removal, reducing energy input, and contributing to system stability and sustainability. This review provides a comprehensive overview of recent advancements, experimental findings, and future prospects, highlighting their potential to revolutionize refrigeration technology for energy-efficient and eco-friendly applications.
