CFD simulations of thermal comfort in naturally ventilated primary school classrooms

摘要: The purpose of Thermal Comfort is to specify the combinations indoor space environment and personal factors that will produce thermal environment conditions acceptable 80% or more occupants within a space. Naturally ventilated indoors has very complex air movement, which depends on numerous variables such as: outdoor interaction, intensity of infiltration, number openings, inertia walls, occupant behaviors, etc. most important mechanism for naturally indoors infiltration buoyancy mechanism. In this study objective was determine indicators comfort for children, by CFD model based experimental measurements with modification turbulent radiant heat transfer mathematical model. The case selected school children aged 8 9 years in primary „France Presern“, Belgrade. evaluate the relationships between subjective responses. Also there analysis stack effect on meterological data site. main parameters were investigated are: operative temperature, concentration CO2 air velocity. new correction turbulence radiative models been validated comparison with using additional statistical indicators. It found both correct and nontransparent media have significant influence set accuracy.
