6 FAQs about [Gypsum as phase change energy storage]
What is the performance of phase change energy storage gypsum board?
Performance of the Phase Change Energy Storage Gypsum Board. According to the physical and mechanical properties’ test method, the 2 h wet flexural strength and compressive strength of the standard phase change energy storage gypsum board and the ordinary gypsum board were measured using a cement bending tester and a pressure testing machine.
What is gypsum phase transition?
This phenomenon corresponds to the phase transition of PCM inside of the composite from solid to liquid. While this is not noticed from the curve of the pure gypsum boards in both test box and reference box. The thermal conductivities of all three boards stabilize after approximately 1.5 h.
How much energy is stored in a gypsum board?
The energy stored in the gypsum board in both the test box and the reference box increases to a maximum of 10 k J / k g before cooling starts, which is less than 1/3 of that stored in the composite board. The extra energy stored in the composite board between 5 and 10 h is due to the phase change in the board.
Can phase change materials improve thermal energy storage capacity?
Integrating phase change materials (PCMs) in building materials is promising for reducing indoor temperature variations, improving indoor thermal comfort as well as minimizing peak power load of heating and cooling [, , , , ]. The thermal energy storage capacity of buildings can be enhanced with the incorporation of PCMs .
Does mpcm change the thermal properties of gypsum?
In addition, the temperature variation and the thermal energy storage of the boards of the two models have been studied. Results indicate that incorporation of mPCM into gypsum will change the thermal properties of the material. PCM can work as an additional insulation layer due to its low thermal conductivity.
What are the mechanical properties of Ca-P/EG phase change gypsum board?
The mechanical properties of the phase change gypsum board decrease with the increase of the CA-P/EG content, but the flexural strength and the compressive strength of the phase change gypsum board exceed 2 and 4 MPa, respectively, which Figure 9. Temperature-change curves of the CA-P/EG phase change gypsum board with different contents.
