Soft water sensible heat storage

What is a sensible heat storage system?

Thermal energy may be stored as sensible heat or latent heat. Sensible heat storage systems utilize the heat capacity and the change in temperature of the material during the process of charging or discharging - temperature of the storage material rises when energy is absorbed and drops when energy is withdrawn.

What is single-medium sensible heat storage?

Single-medium sensible heat storage involves the use of a single material to store thermal energy based on its temperature. Water tanks and rocks are the most common examples of single-medium sensible heat storage. In this type of storage, the thermal energy is directly transferred to the storage medium and stored as sensible heat.

What is the difference between sensible heating and sensible cooling?

Sensible heating or cooling is related to the specific heat of the storage medium and the temperature variation. The latent heat part of the energy variation is usually much higher than the sensible heating or cooling component. For instance, in the case of water, the latent heat of fusion (solid-to-liquid phase change) is hsf = 333.4 kJ/kg.

What is sensitive heat storage (SHS)?

Sensible Heat Storage SHS (Figure 2 a) is the simplest method based on storing thermal energy by heating or cooling a liquid or solid storage medium (e.g., water, sand, molten salts, or rocks), with water being the cheapest option.

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.

What are the advantages and limitations of sensible heat storage?

The key advantages and limitations of sensible heat storage are as follows [68–71]: At a constant temperature, energy cannot be stored or released. The heat storage and release process are more efficient since it does not convert a solid or crystalline structure into a liquid. Easy to load and unload. Insulation can be done quickly.
