Review of Applications of Phase Change Materials for Refrigeration and Air Conditioning

Authors- Professor Dr. M. Rajagopal

Abstract-Phase Change Materials (PCMs) have emerged as an innovative solution for enhancing the energy efficiency and performance of refrigeration and air conditioning systems. PCMs store and release thermal energy during phase transitions, typically from solid to liquid and vice versa, offering a sustainable means of temperature regulation. This review examines the diverse applications of PCMs in refrigeration and air conditioning, including their role in thermal energy storage, integration with refrigeration cycles, building cooling systems, and cold chain logistics. Additionally, it highlights their potential in reducing peak load, improving system efficiency, and extending operational life spans. Despite their advantages, challenges such as low thermal conductivity, high costs, and material stability issues remain. The review also discusses strategies to overcome these limitations, including enhanced materials and system integration techniques. Overall, PCMs present a promising path toward reducing energy consumption, improving comfort, and supporting environmental sustainability in cooling systems, with ongoing research likely to address existing challenges and drive broader adoption in both residential and commercial applications.
