6 FAQs about [Energy storage and heat exchange system]

What is thermal energy storage?

Thermal energy storages are applied to decouple the temporal offset between heat generation and demand. For increasing the share of fluctuating renewable energy sources, thermal energy storages are undeniably important. Typical applications are heat and cold supply for buildings or in industries as well as in thermal power plants.

How effective is a heat exchanger?

As mentioned in Section 2.5, the effectiveness of heat exchanger is usually regarded as an ideal value in previous studies, that is, it is set to be equal in energy storage and energy release phases and is not affected by other parameters.

What is thermochemical heat storage?

Thermochemical heat storage is a technology under development with potentially high-energy densities. The binding energy of a working pair, for example, a hydrating salt and water, is used for thermal energy storage in different variants (liquid/solid, open/closed) with strong technological links to adsorption and absorption chillers.

What is cool thermal energy storage (CTEs)?

Cool thermal energy storage (CTES) has recently attracted interest for its industrial refrigeration applications, such as process cooling, food preservation, and building air-conditioning systems. PCMs and their thermal properties suitable for air-conditioning applications can be found in .

What is underground heat storage based on SHS?

Underground storage of sensible heat in both liquid and solid media is also used for typically large-scale applications. However, TES systems based on SHS offer a storage capacity that is limited by the specific heat of the storage medium. Furthermore, SHS systems require proper design to discharge thermal energy at constant temperatures.

How does a heat exchanger work?

For charging and discharging, a heat exchanger is immersed in the PCM and operated with a HTF. The performance of the storage is limited by the low thermal conductivity of the PCM, typically most limiting the discharge when solid PCM is in contact with the heat exchanging surfaces.
