Varmefeller

A varmefeller, also known as a heat accumulator or thermal storage tank, is a device used to store thermal energy for later use. It is commonly employed in heating systems, solar thermal systems, and industrial processes to improve energy efficiency and reduce costs. Varmefeller can be categorized into two main types: sensible heat storage and latent heat storage.

Sensible heat storage systems use a medium, such as water or a molten salt, to absorb and release heat. When the system is in heating mode, the medium is heated and stored in the varmefeller. During the cooling mode, the stored heat is released to the system. This type of storage is simple and widely used but has limitations in terms of storage density and temperature range.

Latent heat storage systems, on the other hand, utilize phase change materials (PCMs) that absorb or release heat during their phase transitions, typically from solid to liquid or vice versa. PCMs offer higher storage densities and can maintain constant temperatures during the phase change process. However, they are generally more complex and expensive to implement.

Varmefeller are designed to withstand high temperatures and pressures, ensuring safe and efficient operation. They are typically made of materials such as steel, concrete, or specialized alloys, depending on the application and the type of heat storage medium used. The size and capacity of a varmefeller vary widely, ranging from small units for residential heating systems to large-scale installations for industrial processes.

The integration of varmefeller into heating systems can lead to significant energy savings and reduced greenhouse gas emissions. By storing excess heat generated during off-peak hours and releasing it during peak demand, varmefeller help balance the energy supply and demand, contributing to a more sustainable energy infrastructure.
