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.
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.
Conclusion and future work Utilizing PCM-incorporated gypsum boards was shown to be a promising strategy to achieve governmental plans to decrease the energy consumption in buildings. These boards not only can be used in new buildings, but also can be added to existing buildings to improve their thermal performance.
The temperature changes in the 250 mm (9.84”) wall with different percentages of PCM incorporated in gypsum board subjected to T10, T20, and T30 are shown in Fig. 5. As the temperature rises, the PCM absorbs the applied heat energy and turns to liquid, and reducing the peak temperature.
Comparison of the inside temperature oscillation range for the walls with the gypsum board on the inner side vs. the walls with the gypsum board on the outer side. The same results can be reached for cases where the models were subjected to sine temperature profiles with larger magnitudes, i.e. T20 and T30.
The decrement factor decreases as the PCM percentage increases. When 50 vol.% of the gypsum board volume is replaced with PCM and for the input temperature profile with a magnitude of 10 °C (18 °F), this factor can be as low as 8% which means more than 90% of the peak temperature is damped.
