Fasomvandlingsmaterial

Fasomvandlingsmaterial, also known as phase change material (PCM), is a substance that can absorb or release heat by undergoing a phase change, typically between solid and liquid states. This process is known as latent heat storage. PCMs are widely used in various applications due to their ability to store and release large amounts of heat over a narrow temperature range, making them ideal for thermal energy management.

The most common types of PCMs include organic compounds, inorganic salts, and eutectic mixtures. Organic PCMs, such as paraffins and fatty acids, are often used in building materials and clothing for thermal regulation. Inorganic PCMs, like sodium acetate trihydrate and calcium chloride hexahydrate, are used in industrial applications for heat storage and transfer. Eutectic mixtures, which are combinations of two or more substances that melt at a lower temperature than their individual components, are used in specialized applications where precise temperature control is required.

PCMs can be integrated into building materials, such as concrete and plaster, to improve energy efficiency by reducing heating and cooling loads. They are also used in thermal energy storage systems, where they store excess heat generated during peak production times and release it when demand is high. In the textile industry, PCMs are used in clothing and bedding to provide temperature regulation, keeping the wearer comfortable in varying environments.

The selection of a PCM depends on the specific application requirements, including the desired phase change temperature, thermal conductivity, chemical stability, and cost. Research is ongoing to develop new PCMs with improved properties and to optimize their integration into various systems for enhanced thermal management.
