建筑材料中挥发性有机化合物（VOC）的释放速率和室内浓度受温度的影响。地板辐射供暖系统在韩国的大多数住宅建筑中广泛使用，地板材料的VOC排放量随着地板温度的升高而增加。在这项研究中，提出了一个数值模型来评估VOC的排放量从建筑材料在不同的温度取决于加热条件。建立了地板采暖空间内建筑材料温度变化和VOC排放的耦合模型，该模型将建筑材料和室内空气温度的传热模型与VOC排放和室内VOC浓度的传质模型相结合。通过模拟试验验证了模型的有效性，并利用该模型研究了地板材料在不同加热条件下的辐射特性。结果表明，地板材料的挥发性有机化合物的排放量有增加的趋势，地板温度升高，在加热条件。
The emission rates of volatile organic compounds (VOC) from building materials and the resulting indoor concentrations are influenced by temperature. Radiant floor heating systems are widely used in most residential buildings in Korea, and VOC emissions from flooring materials increase as the floor temperature rises. In this study, a numerical model is presented to evaluate the VOC emissions from building materials at different temperatures depending on the heating conditions. A coupled model is developed to simulate the temperature variation of building materials and VOC emissions in the floor heated space, which combines the building heat transfer model for materials and indoor air temperature with the mass transfer model for VOC emissions and indoor VOC concentrations. The model was validated by a mock-up test, and it was then used to examine the emission characteristics from flooring materials under different heating conditions. The results show that emissions of VOC from flooring materials tend to increase as the floor temperature rises during the heating condition.
