Epc application design of phase change energy storage materials

Are phase change materials suitable for thermal energy storage?

Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.

What are phase change materials (PCMs) for thermal energy storage applications?

Fig. 1. Bibliometric analysis of (a) journal publications and (b) the patents, related to PCMs for thermal energy storage applications. The materials used for latent heat thermal energy storage (LHTES) are called Phase Change Materials (PCMs) .

What are phase change energy storage materials (pcesm)?

1. Introduction Phase change energy storage materials (PCESM) refer to compounds capable of efficiently storing and releasing a substantial quantity of thermal energy during the phase transition process.

Are SS-PCMS a new composite phase change material?

Therefore, extensive research mainly focuses on the shape-stable PCMs (ss-PCMs) as new composite phase change materials. SS-PCMs are usually composed of PCMs and porous materials, in which PCMs are used for thermal energy storage, and porous materials are used as shape stabilizers and thermal conductivity enhancers.

Are composite phase change materials encapsulated in building materials?

In their study, PCMs were encapsulated in building materials using attapulgite and fly ash as support materials. The results show that the composite phase change materials have good mechanical and thermal properties. Therefore, they have important potential for thermal regulation and energy saving in buildings.

What are solid-liquid phase change materials (PCMs)?

Solid-liquid phase change materials (PCMs) have become critical in developing thermal energy storage (TES) technology because of their high energy storage density, high latent heat, and excellent constant temperature performance during phase change.
