摘要:
为解决传统砌块材料导热系数大、吸湿率高的问题，本研究制备了低吸湿率玻化微珠水泥基材料，测试了标准养护室连续7d吸湿量及吸湿后导热系数变化规律。同时，基于一维稳态传热理论，利用ABAQUS模拟了砌块热工性能，并采用ECOTECT进行建筑的热分析。结果表明:玻化微珠水泥基导热系数低，可以大幅降低砌块内表面热流强度、内表面温度，有效增加砌块的热阻，提高砌块的热工性能，并且可以有效降低潮湿环境的影响。玻化微珠砌块用于建筑外墙可以降低建筑能耗，暖通空调系统(HAVC)负荷、围护结构得失热(FABRIC)值以及被动组分得失热，且外墙吸湿后仍可以有效降低建筑能耗，维持建筑舒适性。
Abstract:
In order to solve the problems of high thermal conductivity and high moisture absorption of traditional block materials, the vitrified microbead cement-based material with low moisture absorption were prepared in this study, and the moisture absorption of standard curing room for 7 consecutive days and the change rule of thermal conductivity after moisture absorption were tested. At the same time, based on one-dimensional steady-state heat transfer theory, the thermal performance of the block was simulated by ABAQUS, and the thermal analysis of the building was conducted by ECOTECT. Test results show that the thermal conductivity of vitrified microbead cement is low, and it can significantly reduce the heat flux intensity and temperature on the inner surface of the block, as well as effectively increase the thermal resistance of the block, so as to improve the thermal performance of the block, and effectively reduce the influence of humid environments. The vitrified microbead block used for building exterior walls can reduce building energy consumption, as well as the heating, ventilation, and air conditioning (HVAC) load, fabric gains and losses (FABRIC) value, and passive component heat gain and loss, and the exterior wall can still effectively reduce building energy consumption and maintain building comfort after moisture absorption.
