The choice of the scheme of air distribution from ventilation and air-conditioning systems in the hall of the small indoor ice rink
Annotation
This paper examines the impact of the scheme of air distribution from ventilation and air conditioning systems on the characteristics of the fields of temperature and humidity over the ice surface areas in the indoor ice rink. Reveals the influence of air movement on the distribution of parameters over the ice, and on the condition of the ice surface. Graphs of air temperature over the ice platform height, formed in the heat exchange process the results of measurements of the author and from other sources. Presents a graph of the moisture content of the air on the basis of data obtained by the author, illustrating the intensity of mass transfer. It is proposed to use the scheme of air distribution, tested on a number of sites, excluding the direct impact of air jets on the ice array. The design procedure of the proposed scheme taking into account ensure the necessary air movement over the ice.
