Résumé

In the current study, research on developing air conditioning systems by employing several kinds of ideas to conditioning spectators' zone in football stadium. The main task is to find out the air conditioning effect on the spectators and calculating thermal comfort and analyze the model was to ensure the better method to distribute air to achieve the human comfort for spectators inside the stadium and CFD provides guidance on how to improve the performance of air distribution by selecting the places of supply and return air diffusers and get the influence of air on spectators and calculate the mean velocity and temperature that are used to determine the thermal comfort indices PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied) and to evaluate the thermal conditions in the various regions of the stadium. From the study it is found that the best method for conditioning the spectator zone is supplying the air from above jet air nozzles and pulls the return air from diffusers behind the seats to get the best distribution of air and achieve the human comfort and to improve the air-conditioning can be installed the radiant cooling system by using cold water pipes within the stadium's structure to reduce heat loads.
