Phase Changing Material (PCM) Thermal Storage

About

Phase Change Material (PCM) thermal storage technology leverages materials that absorb and release large amounts of energy during phase transitions, typically from solid to liquid or vice versa. This process, known as latent heat storage, allows PCMs to store thermal energy at a constant temperature, making them highly efficient for storing and releasing heat or cold. PCMs are categorized into organic, inorganic, and eutectic types, each with unique properties and applications. Organic PCMs, such as paraffins and fatty acids, are commonly used in textiles and buildings. Inorganic PCMs, like salt hydrates, offer better thermal conductivity and are often used in industrial settings. The use of PCMs in thermal storage enhances HVAC efficiency by shifting heating and cooling loads to off-peak hours, reducing energy costs and the strain on equipment. This technology is versatile, applicable in various sectors including buildings, electronics, and textiles. By storing thermal energy during off-peak times and releasing it during peak demand, PCMs help stabilize grid loads and reduce carbon footprints. Additionally, PCMs can be integrated into walls and roofs to act as thermal batteries, providing passive cooling and heating solutions. Overall, PCM thermal storage offers a sustainable and cost-effective method for managing thermal energy needs.
