Are sensible and latent heat storage materials suitable for thermal energy storage?

It is worth noting that using sensible and latent heat storage materials (SHSMs and phase change materials (PCMs)) for thermal energy storage mechanisms can meet requirements such as thermal comfort in buildings when selected correctly. 1. Introduction

What is latent heat and sensible heat?

Latent heat and sensible heat are two forms of energy that are used in explaining the relationship between the temperature and matter. These terms have many applications in our day to day life. The latent heat is the transfer of energy from or to a system during a phase transition of matter.

Is heat storage a latent heat?

Heat storage as latent heat for the case of solid-liquid phase change . Classification of PCMs (reproduced from ). Comparison of organic PCMs .

How is sensible heat thermal storage achieved?

Sensible heat thermal storage is achieved by heating the storage medium (liquid sodium, molten salt or pressurised water) and increasing its energy content but not changing state during accumulation. Energy is released and absorbed by the medium as its temperature reduces and increases respectively.

What are the characteristics of heat storage?

In heat storage, use is made of the thermal capacity of solid or liquid materials, either by their sensible (specific) heat effect (heating/cooling cycles) or by their latent heat effect at a phase change (melting/freezing cycles). For heat storage, the important thermal characteristics are: Heat capacity. MJ/m 3

Can high thermal mass materials be used for latent heat storage?

The use of high thermal mass materials (most commonlywater) is discussed below and was evaluated as part of this project. Latent heat storage consists in storing energy by through phase change of the storage medium, which is usually solid-liquid. Phase change materials have been known and investigated for several decades.
