Application of Phase Change Material Energy Storage Structure in Prefabricated Cabin of Substation and Analysis of Energy Saving Effect
In this paper,the application of phase change materials(PCM)in high internal heat source buildings such as prefabricated cabins in substations and the design optimization in walls are studied.From the perspective of reducing the energy consumption of air conditioning throughout the year and regulating the temperature and energy conservation of peak power grid load,the optimal design scheme of phase change materials in the wall structure of prefabricated cabin of substation is studied around the installation position and thickness of the wall.The simulation of typical daily energy consumption shows that the phase-change material is designed close to the inner side of the wall,which has more energy-saving effect.In addition,the optimized design thickness of the phase-change material is 25 mm,considering the strength of the internal heat source of 600-1 000 W.The PCM makes the inner surface temperature of the wall have the typical characteristics of"peaking",and has obvious effect of temperature regulation and energy saving.
