To calculation of thermal and moist loadings ice skating rinks Loading from radiantheat transfer
Annotation
Work is devoted to calculations of thermal loadings of an ice skating rink, in particular loadings from radiant heat transfer. The method of calculation of radiant heat transfer rate is given in 1 part from surrounding surfaces for skating rinks in the closed rooms. Comparison of the given technique with a technique from the directory [7], widely applied among engineers is carried out today. Ways of decrease in loading from athermal radiation by use of reflecting screens and special materials for a ceiling are given. In 2 parts the task from air conditioning area by determination of parameters of the air environment in a hall of a covered skating rink at which formation of condensate on the surfaces cooled at the expense of athermal radiation is possible is considered. Calculations for halls of ice arenas of three sizes – a training skating rink, the ice arena with tribunes on 3000 viewers, the large ice arena with tribunes on 15000 places are given. In 3 parts regularities of heattransfer from solar radiation on an ice surface of a skating rink open-air are considered. Calculation of coefficients of absorption of solar radiation for set of visible and infrared ranges of a solar range is given. The method of calculation of a heat transfer rate is given to 4 parts from the artificial lighting, submitting to laws of thermal radiation. Modern illuminants are considered.
