Study on the Influence of Thermal Properties of Building Envelope on Indoor Pollutant Diffusion
At present, China is in a critical period of 70% energy saving in buildings. In order to meet people’s needs for indoor lighting and permeability, the south wall of the same residence in cold region is replaced with the floor-to-ceiling window of Low-E glass in this paper. The realizable k − ε model was used to analyze the influence of outdoor environment conditions on indoor pollutant diffusion process and thermal comfort through different building envelope structure. The results show that the floor-to-ceiling window structure restrains the diffusion of pollutants from the floor at night. After 19 h diffusion, the average concentration value of indoor pollutant in the floor-to-ceiling window structure is 25.7% lower than that of the external wall structure. At this time, the indoor PMV values of the floor-to-ceiling window structure and the external wall structure are 0.14 and 0.05, respectively. And the average indoor temperature of the floor-to-ceiling window structure can meet the requirements of the average indoor temperature of floor heating.
