Effect of distance between occupants and insulation performance of window on contaminant distribution in a room with displacement ventilation

In recent years, displacement ventilation system has received much attention in terms of infectious disease control, due to the epidemic COVID-19 infections. Plume from occupants and other heat sources is a very important factor for because it determines height contaminant stratification. Therefore, this paper aims at effect distance between on distribution temperature, concentration plume CFD analysis first. The results suggest specific where occupant interfere with each occupied zone. Our also indicate that conditions such as human body posture affect interference. addition, since aforementioned study don't take into account influence temperature window surface cooled by outside air, we vary insulation performance check area. are obtained amount contaminants carried downward flow lower part room depends window, which affects
