Dependence of the Microclimate Parameters at the Boundary of the Room Serviced Area on the Size of the Window

The values of the radiation temperature and the local asymmetry of the radiation temperature in the premises of buildings with respect to the ball thermometer were estimated by mathematical modeling of the process of radiant heat exchange of each inner surface with a ball thermometer. The ordinary rooms of the intermediate floor of medical and preventive, preschool institutions and residential boarding schools in Belgorod with an estimated outdoor temperature of -24⁰C in the cold period of the year are considered. The aim of the work was to find out the influence of the window size in the rooms with a heating facility on the above microclimate parameters. Windows with standard resistance to heat transfer were taken for consideration, the height of which varied from 1.3 m to 2.3 m, and the width from 0.8 m to 3.8 m. The calculation results show that in the design winter conditions, the optimal requirements of GOST for radiation temperature are often not met. The requirements for local asymmetry of radiation temperature are also not met. The heating facility, in comparison with the air heating, noticeably raises the radiation temperature both at a height of 0.4 m from the floor opposite the heating device and at a height of 1.7 m opposite the window.
