Regarding the issue of maintaining humidity in the hall of the indoor ice rink
Annotation
The paper reveals some issues related to the problem of maintaining humidity in the indoor ice rink. Requirements of various normative documents to the level of humidity in ice halls are given. The approaches to the regulation adopted in domestic and foreign practice are analyzed. The main sources of moisture release that make up the moisture balance of the rink hall are considered. The method of calculating the average volume level of humidity in the room when changing the intensity of moisture and modes of operation of the microclimate maintenance system is proposed. The calculation of the dynamics of moisture content in the hall of the standard training rink used in different modes of operation at different flow rates and parameters of the air supplied to the volume by the air conditioning system. The features of condensation and adsorption method of dehumidification used to maintain humidity in ice halls are considered.
