Verification of compliance with the requirements of the norms for the internal microclimate of a corner room

Abstract

The article considers the buildings of the transport infrastructure that provides services to transport workers, e.g. medical and preventive, children's educational and educative institutions. The resistance to heat transfer of the windows was not increased for such buildings at the last change in the norms of thermal protection in the Russian Federation in 2018. In this regard, it is important to check compliance with the requirements of regulatory documents for radiation temperature and asymmetry of the radiation temperature at the boundary of the serviced area of the premises of such buildings. A literary review has shown that much attention is paid to these parameters in the world. Since the heat transfer resistance of the windows is much less than that of the outer walls, the influence of the outside air temperature on the temperature of the inner surface of the window is much greater than that of the walls. The proposed article considers a corner room of an intermediate floor with windows in the outer walls, occupying 35% of the area of the external enclosing structures, in Belgorod. The building is serviced by air heating. A comparison of the radiation temperature and the asymmetry of the radiation temperature with the same indicators in the ordinary room considered earlier showed that with windows of the specified size, the influence of the second window significantly reduces the radiation temperature and increases the values of the local asymmetry of the radiation temperature. At the same time, during the estimated winter period, not only optimal, but also permissible requirements of the regulatory document are not met at the border of the serviced area of the premises.
