Abstract
One of the most promising applications of highly effective computer technology (supercomputers) is numerical simulation of complex physical and thermophysical proccesses occuring in vast areas of concert halls and sport arenas while heating, ventilating and air conditioning. According to Russian technical standarts for building construction, numerical modeling of these systems should be carried out on the stage of their design. The variety of problems and demands, lack of understanding of the physical process involved and the necessity to make genuine decisions are encountered while conducting such a work. The experience in modeling of ventilation and air conditioning systems of Bolshoi Krenlevskyi Palace concert halls and the Moscow Conservatory named after P.I. Chaikovskyi, Zaryadie Park Philarmony concert hall and a covered ice rink arena is described.
Highlights
Great attention is being paid to the conditions for spectators and athletes when considering a modern sports complex or a civic centers design [1,2]
The results of velocity and temperature fields modelling with air supply of 43 m3/h per one spectator and their heat release of 72 W are shown in Fig
We have carried out many numerical simulations of ventilation and conditioning systems for different in-door sport facilities and city halls
Summary
Great attention is being paid to the conditions for spectators and athletes when considering a modern sports complex or a civic centers design [1,2]. The local temperature difference of the comfort zone height (i.e. the range of 0.1 to 1.5 m), should not be more than 3 °С, and air velocity change should not exceed 0.1 m/s (50 %) This design procedure is rather challenging because of the complex configuration of the buildings, the differences in heating loads and ventilation system layout. This fact is reflected in the modern Russian building standart SP60.13330.12 “Heating, ventilation and air conditioning”, which requires ensuring the specified parameters of the microclimate in residential, public, administrative and industrial buildings by means of mathematical modeling (GOST 30494-11). Computation machines performance growth and an improved numerical algorithms make it possible to discretize solution in a large irregular domain without precision loss by 10 to 100 million elements
