Simulation and optimization analysis of indoor ventilation for an underground space in a public construction project in Guangzhou
Good ventilation in underground spaces can improve the indoor environment,regulate the thermal and humidity conditions,and enhance the air quality,providing users with a healthy and comfortable space for leisure and entertainment.Taking a public construction project in Guangzhou as the research object,combined with the results of outdoor site wind pressure calculations,the positions and sizes of the courtyards are optimized.Using the Airpak software,the wind speed and air change rates under various conditions are simulated and calculated.The results show that by adjusting the positions,sizes,and combinations of ventilation openings,the indoor ventilation conditions can be effectively improved.
