| description | In recent years, China has continuously increased the construction of sports facilities, with the number and area of sports venues steadily growing. The use of more energy-efficient ventilation methods in gymnasiums has become one of the research hotspots. Taking a multi-functional gymnasium in Wuhan as an example, the gymnasium adopts a seat air supply device driven by natural wind to enhance indoor ventilation. This study uses the methods of field measurement and CFD simulation to analyze the application effect of this new type of natural ventilation device in hot summer and warm winter areas during the transition season. Through CFD simulation of the ventilation performance of the seat air supply at different opening rates, the indoor ventilation effect and thermal comfort were analyzed. The application of the seat air supply greatly improved the indoor environment and enhanced the comfort of personnel. After turning on the seat air supply, the maximum temperature difference between the indoors and outdoors increased from 1.7 °C to 3.4 °C, the natural air intake rate increased from approximately 50% to approximately 70%, the wind speed in the seat area significantly increased, the uniformity of the wind speed field in the movement area significantly increased, and the proportion of areas with low wind speed and no wind speed decreased to 9.6%. The proportion of areas with wind speeds ranging from 0.3 to 0.5 m/s increased from 8.8% to 33.0%. At 10:00 a.m., the temperature at the indoor station was relatively low. The opening of the seat air supply device reduced the <i>PMV</i> value of the front seats by an average of 0.39. When the indoor platform temperature reached the maximum value, the impact of equipment activation on the <i>PMV</i> index of the seat area was relatively small, with an average reduction of only 0.19. The research results show that the application of a natural wind-driven seat air supply in sports venues is very promising, providing a new idea for the energy-saving renovation of gymnasiums and effectively promoting the development of low-carbon undertakings. |
