Valley electric high temperature energy storage heating

Can Valley power phase change heat storage be used in commercial buildings?

The heating tests in commercial buildings show 53% savings in operating costs. The valley power PCHS heating technology shows good application prospects. The application of valley power phase change heat storage (PCHS) in commercial building heating has practical significance for the city's sustainable development.

How can a valley power PCHS system predict the energy storage duration?

Therefore, in the application of the system, it is possible to predict the energy storage duration and the amount of heat storage of the valley power PCHS system based on the building energy consumption data and the outdoor ambient temperature parameters of the heating seasons over the years.

What are the advantages of Valley power PCHS system?

As a result, based on the operation data and economic analysis of the commercial building, it can be seen that the valley power PCHS system applied to the winter heating of commercial buildings has the advantages of high energy storage density, stable energy storage temperature, flexible operation, modular installation and regulation.

What is sensible heat storage?

Sensible heat storage is so far the most widely used way of heat storage in building heating. 13 Water heat storage is the oldest and most technically mature way of sensible heat storage with high specific heat, low costs and good heat transfer and fluidity.

Why is heat storage important?

Heat storage has been proven to be an effective way to fill the gap between energy supply and demand in building heating, it has demonstrated tremendous potential in advancing the utilization of renewable energy for clean heating.

What is latent heat storage?

In latent heat storage, heat is stored through the heat absorption/release behaviour of the material during phase change, within the medium-low temperature interval. The most frequently used phase change heat storage materials include paraffin and inorganic salt hydrates.
