摘要
低碳相变混凝土是以低碳胶凝材料和相变骨料为原料制备的相变储热混凝土,这类混凝土降低了相变混凝土制备过程的碳排放,但其在建筑中的实际节能效果仍需系统研究.基于此,利用EnergyPlus软件设计办公建筑模型和空调运行制度,计算低碳相变混凝土的厚度和布置方式对空调能耗的影响,分析低碳相变混凝土在不同气候区的节能效果.结果表明,相变温度为26℃的低碳相变混凝土的最佳施工厚度为 2～3 cm,最优布置位置为办公建筑的内隔墙,最佳应用气候区为夏热冬冷地区和夏热冬暖地区.
Abstract
Low-carbon phase change concrete is a type of phase change thermal storage concrete prepared using low-carbon ce-mentitious materials and phase change aggregates.This type of concrete reduces the carbon emissions during the preparation process of phase change concrete.However,its actual energy-saving effect in buildings still requires systematic research.In this study,EnergyPlus software was used to design an office building model and HVAC operation system to calculate the impact of thickness and arrangement of low-carbon phase change concrete on HVAC energy consumption,and analyze its energy-saving effect in different climatic zones.The results show that the optimal construction thickness for low-carbon phase change concrete with a phase change temperature of 26℃ is 2～3 cm.The ideal placement of low-carbon phase change concrete is within the in-ternal partition walls of office buildings,and the best climatic zones for its application are summer hot-winter cold regions and summer hot-winter warm regions.
