What is phase change energy storage?

When combined with traditional building materials, they can be made into phase change energy storage building materials, effectively storing heat/cooling in the form of latent heat of phase change, greatly extending the thermal insulation performance of building walls over long periods of time.

How to design a thermal energy storage building with phase change material?

Given the solar irradiance E and outdoor temperature, the thermal energy storage building with phase change material is modeled with five parts: the air inside the phase change wall, the phase change material, the indoor air, the inner surface of the phase change wall, and the inner surface of other wall components.

What is the difference between CHP and phase-change energy storage?

CHP units help improve the output efficiency of solar thermal power generation, while building phase-change energy storage helps alleviate the constraints of the unit's thermal-electric ratio.

Should waste heat recovery be included in the integrated energy supply model?

In the initial design phase of the integrated energy supply model for a combined heat and power (CHP) solar thermal power plant with phase-change energy storage, waste heat recovery was not considered to simplify the problem. However, this approach has its drawbacks, as waste heat recovery should be a crucial aspect of the CSP plant design.

Is solar thermal power a good option for island regions?

Solar thermal power generation with thermal storage exhibits good synergy and is suitable for power supply in island regions, but it involves high construction costs and difficulties in large-scale implementation.

What are phase change materials?

Phase change materials are a novel and efficient form of thermal storage/cooling. During their phase transition process, they can absorb heat/cooling from the environment and release heat/cooling to the environment when needed, thereby controlling the surrounding temperature.
