Research on Factors Influencing Indoor PM[sub.2.5] Concentration in Curling Venues Based on CFD Simulation
This article explores the effects of outdoor PM[sub.2.5] concentration, venue airtightness and the distribution of indoor PM[sub.2.5] concentration on the curling venue of the National Aquatics Center. Research has found that when the filtration efficiency of the fresh air system is 60%, the outdoor...

| description | This article explores the effects of outdoor PM[sub.2.5] concentration, venue airtightness and the distribution of indoor PM[sub.2.5] concentration on the curling venue of the National Aquatics Center. Research has found that when the filtration efficiency of the fresh air system is 60%, the outdoor PM[sub.2.5] concentration increases by 20 μg/m[sup.3], an average increase of 6 μg/m[sup.3] in indoor PM[sub.2.5] concentration. When the venue air tightness is good, the outdoor air quality has no significant impact on the average indoor PM[sub.2.5] concentration. But as the number of infiltration air changes increases, the indoor PM[sub.2.5] concentration in each region shows an upward trend. The end of the air conditioning system in the competition area adopts bag air duct supply mode, which can reduce the concentration of PM[sub.2.5] in the competition area by 93%, and the moisture content is reduced to 2–2.5 g/kg, better meeting the requirements of curling competitions. |
