Summary

Advances on developing air conditioning systems in sports facilities by employing several technologies to cool the indoor/ outdoor spaces such as stadiums and sports arenas is underway to save energy and provide thermal comfort . The most serious challenge of air conditioning in outdoor spaces is the difficulty to control the temperature and humidity in the open spaces and also the enormous energy needed by the cooling system. The main task for the analysed model was to ensure the better method to distribute air to achieve the human comfortable for players and spectators inside the sport facility .The present work aimed to investigate the technical aspects addressed to study the air conditioning system effectiveness using Computational Fluid Dynamics CFD code to determine the best way to distribute the air inlets and simulating the flows in air to overcome the high temperature and humidity to reach acceptable human comfort. Examples are given here for squash arenas, handball playground and soccer fields. The current paper numerically investigates the influence of location and number of air conditioning supply and extracts openings on air flow properties in spectators’ area within sport facility. The present work focuses on predicting air flow patterns and thermal behaviour through investigating of the air flow regimes and moisture content inside the spectators’ area. Furthermore, the work investigates the heat transfer behaviour through analysing temperature and relative humidity profiles within the area. The present investigation made use of Computational Fluid Dynamics (CFD) simulation techniques.
