相变储能石膏板应用于地板供暖系统的节能效果及热舒适性分析

Analysis on Energy-saving Effects and Thermal Comfort Performance of Floor Heating System using Phase Change Energy Storage Plasterboard

本文针对一种电加热相变地板供暖系统,通过模拟计算分析了其稳定性和热舒适性,并通过实验进行了验证。模拟计算结果表明相变地板供暖系统储热能力好,与普通地板供暖系统相比,室内空气温度变化平缓,人体舒适度更高。相变地板利用相变材料储存廉价低谷电热能,系统的节能性和经济性较好。

In this paper,for the electric heating system with phase change floor,the stability and thermal comfort performance were analyzed through the simulation,and the results were validated by the experiments.It was concluded that the phase change floor heating system had good heat storage ability.When it was compared with the common floor heating system,the indoor air temperature changed more gently and occupants had higher thermal comfort level.Furthermore,phase change material could store the cheap electrical heat energy during night,therefore the energy-saving effects and economic features of the system were much better than the common floor heating system.
