Numerical Simulation And Optimization Of Air Distribution In Badminton Gymnasium

Because the air flow in the badminton hall has a great impact on the badminton game itself,and there are many troubles caused by the air conditioning system in the international badminton competitions,so the air conditioning design of the badminton hall has drawn special attention.Badminton venues are required to have a clear clearance of 9.0m without obstacles,and the national regulations specify that the wind speed in small ball venues shall not exceed 0.2m/s.From existing engineering examples and air conditioners running situation survey,the situation is not optimistic,inside hot phenomenon is more common,and venues are tall space,in the energy conservation and environmental protection policy,under the guidance of the air conditioning system as large energy consumption,air conditioning system within the venue design puts forward very high requirements,so the study of badminton hall air conditioning air distribution and optimization is of great significance.In this paper,numerical simulation(CFD)method is adopted to study the air flow distribution of air conditioning,and Airpak simulation software is used for analysis and research.Badminton hall was established physical model and mathematical model of numerical simulation of air distribution,through the engineering design of a badminton hall air conditioning air distribution are analyzed in numerical simulation,give next time to build,side send next time and lower to send back to the design of three kinds of air flow in the model through the contrast analysis of site to different schemes are obtained in the distribution of velocity field and temperature field.The results show that when the upflow and downflow are adopted,as for the badminton hall with a height of 9m,the airflow distribution in the venue still fails to meet the requirements and the air conditioning energy consumption is relatively high when the air velocity of the air supply jet is controlled within 1.0m/s.In the form of side airflow,high-speed jet flow enters the competition site directly.The percentage of substandard wind speed exceeds 10% in the whole space,and the local wind speed exceeds0.5m/s,which cannot meet the requirements of badminton competition.Based on the numerical simulation results,this paper proposes to adopt the medium and low air supply mode.The simulation results show that the velocity field and temperature field in the site are satisfactory,and the vertical temperature gradient of the stratified air conditioner is obvious,and the energy saving effect is remarkable.In this paper,numerical simulation method is used to study and optimize the air distribution of the air conditioner in the badminton hall.
