6 FAQs about [Sensible heat energy storage equipment]

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of charging or discharging - temperature of the storage material rises when energy is absorbed and drops when energy is withdrawn.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 a thermal energy storage system?

By heating (or cooling) a storage medium, thermal energy storage systems (TES) store heat (or cold). As a result, further energy supply is not required, and the overall energy efficiency is increased. In most cases, the stored heat is a by-product or waste heat from an industrial process, or a primary source of renewable heat from the sun.

What are the thermal properties of sensible heat storage materials?

The amount of stored heat is proportional to the density, specific heat, volume, and temperature variation of the storage materials. Basically, specific heat, density and thermal conductivity are the main thermal properties of sensible heat storage materials. Fig. 1 shows the main thermal properties of sensible heat materials.
