What are encapsulated phase change thermal storage systems?

Encapsulated phase change thermal storage systems represent a novel and effective alternative to shell-and-tube vessels. They encapsulate PCM in multiple sub-vessels within the M-TES container, thereby enhancing heat transfer performance through an increased surface area for heat exchange.

Are spherical and cylindrical phase change thermal storage units effective?

In summary, while substantial research has been conducted on spherical and cylindrical phase change thermal storage units, there is a notable lack of studies on the thermal storage performance of plate-type phase change units and containers combining multiple plate phase change units.

What are the characteristics of phase change materials used in energy storage?

Phase change materials used in energy storage typically exhibit thermal properties such as appropriate phase change temperatures, high latent heat of transformation, effective heat transfer, and physical properties including favorable phase equilibrium, high density, minimal volume change, and low vapor pressure .

What are the types of phase change thermal energy storage vessels?

Based on different vessel structures and heat transfer mechanisms, phase change thermal energy storage vessels can be classified into direct-contact and non-direct-contact types. Non-direct-contact phase change thermal storage vessels include shell-and-tube and encapsulated types based on the PCM encapsulation method [5, 6].

What is encapsulated phase change thermal storage vessel (HTF)?

During the heat storage process of encapsulated phase change thermal storage vessels, the HTF completely surrounds the PCM sub-vessels, facilitating heat exchange between the vessel wall and the phase change material.
