备注

充气膜结构体育馆和传统结构体育馆主材热工性能不同,造成两种结构体育馆的室内热环境响应明显不同.本文对蒙中地区充气膜结构和传统结构体育馆进行实地调研,对两者的室内外空气温度、空气流速、壁面温度、太阳辐射照度等参数进行测量,并选取5项评价指标(温度波动、温度均匀度、垂直空气温差、吹风感指数及PMV)对比分析两种结构体育馆室内热环境的差异性.研究结果表明:充气膜结构体育馆室内外空气温度的延迟时间较短,约为55 min,而传统结构体育馆延迟时间约为100 min; 充气膜结构体育馆站姿人群垂直温差可达2.26 ℃,传统结构体育馆最大为0.55 ℃,充气膜结构体育馆坐姿人群aPMV为-1.40,而传统结构体育馆为-0.92,造成充气膜结构体育馆的热环境舒适性较差,并且太阳辐射照度越强,两者差异性越大.为了提高体育馆热舒适性,充气膜结构体育馆的建议操作温度范围为9.48~13.11 ℃,传统结构体育馆的范围为8.19~11.81 ℃.
The thermal performance of the main materials of gymnasium with inflatable membrane structure is different from that of gymnasium with traditional structure, resulting in significantly different indoor thermal environmental responses of the two kinds of gymnasiums. In this study, a field research was carried out on the two kinds of gymnasiums in central Mongolia, and the indoor and outdoor air temperature, air velocity, wall temperature, solar radiation illuminance and other parameters were measured, and then, five evaluation indexes(temperature fluctuation, temperature uniformity, vertical air temperature difference, blowing sensation index and PMV)were selected to compare and analyze the difference of indoor thermal environment of two kinds of gymnasiums. The research results show that the delay time of indoor and outdoor air temperature in the gymnasium with inflatable membrane structure is relatively short, about 55 minutes, while the delay time of the gymnasium with traditional structure is about 100 minutes; the vertical temperature difference of the standing crowd in the gymnasium with inflatable membrane structure can reach 2.26 ℃, while the maximum temperature difference of the gymnasium with traditional structure is only 0.55 ℃, and the aPMV of people sitting in the gymnasium with inflatable membrane structure is -1.40, while that in the gymnasium with traditional structure is -0.92, resulting in poor thermal environment comfort in gymnasium with inflatable membrane structure, and the stronger the solar radiation illuminance, the greater the difference between the two. In order to improve the thermal comfort of the gymnasium, the recommended operating temperature range of the gymnasium with inflatable membrane structure is 9.48~13.11 ℃, and the range of the gymnasium with traditional structure is 8.19~11.81 ℃.
