6 FAQs about [Latent heat storage tank]

What is latent heat storage?

Latent heat storage refers to the storage or release of thermal energy during its phase change. When a solid Latent Heat Storage Material (LHSM) is heated, it’s sensible heat increases until it reaches the melting point. From the initiation of melting to the completion of melting the significant amount of heat is stored in the form of latent heat.

Why is the heat storage performance of latent heat storage systems not good?

The heat storage performance of latent heat storage systems is not good due to the poor thermal conductivity of phase change materials.

What is latent heat storage (LHS)?

Latent heat Storage. The latent heat storage (LHS) commonly uses the heat of fusion of melting and solidifying of material, rather than evaporation and condensation, due to the large volume change associated with the latter. The use of phase change materials (PCMs) as base materials for TES increased since the energy crisis in the 1970 s.

What is latent heat?

Latent heat provides substantially high energy storage density and maintains small temperature difference between the storage and release of heat . LHSMs can be of the form Solid–Solid (S–S), Solid–Liquid (S–L), Solid–Gas (S–G) and Liquid–Gas (L–G) based on the transformation type.

What is the enthalpy of a latent heat storage system?

A latent heat storage system using NaNO 3 as PCM with a melting temperature t PC of 306 °C and a phase change enthalpy of 177 kJ/kg is charged using saturated steam at 315 °C/105.5 bar. During discharge, saturated steam at 295 °C/80 bar is generated.

What is the theoretical analysis of latent heat storage systems?

In this section, an overview of the theoretical analysis of latent heat storage systems is provided, with an emphasis on concepts involving integrated heat exchangers. This analysis supports the optimization of the geometry of the storage system and is also needed for the development of control systems.
