Abstract
Statement of the problem. The aim of the work is to construct a numerical model of complex radiation-convective heat exchange of the roof structures of an indoor skating rink with moist air of the upper zone to identify the dependencies of the increase in the velocity and area of condensation of water vapor on the height of the room Results. Based on the results of a numerical study of the process of complex non—stationary heat exchange of the system «surface of the floor structure — indoor air –– ice surface», theoretical dependences of the increase in the velocity and area of condensation of water vapor from the vertical coordinate under the action of radiation cooling from the ice field were obtained for the first time. Conclusions. The obtained dependences allow us to theoretically justify the choice of rational technical solutions and operating modes of ventilation and air conditioning systems in the upper zone to prevent condensation on the internal surfaces of building and enclosing structures.
