南方地区过渡季体育训练馆多种强度运动人群热可接受度研究

Study on Thermal Acceptability of Multi-Intensity Sports in Transitional Season Sports Training Center in Southern China

为了研究南方地区过渡季中,不同强度的运动对运动人群热感觉及热接受度的影响。笔者对南方地区典型的多层叠合的自然通风体育训练馆及其运动人群进行实测调研,分别采集其室内热环境参数和运动人群的主观信息,建立了热感觉与操作温度的回归方程及热可接受度与操作温度的回归方程,分析了四种活动的适应性热舒适模型及热舒适范围的区别。研究结果表明,运动人群的热感觉会受到室内热环境的影响,随着运动强度的升高,运动人群的热感觉受到热环境的影响会相对更小;随着运动强度的增高,可接受温度的上限和下限大致呈现出两者都下降的趋势;同时随着运动强度的增加,可接受温度的范围也会减少。

This paper aims at studying the effects of different intensity of exercise on the thermal sensation and thermal acceptability of the sports crowd in the transitional season in southern China.The indoor thermal environment parameters and the subjective information of the sports crowd were collected through the field survey of the typical multi-story superimposed natural ventilation sports training center and its sports crowd in southern China.The regression equation of thermal sensation and operating temperature and the regression equation of thermal acceptability and operating temperature are established.The adaptive thermal comfort model of five activities and the difference of thermal comfort range are analyzed.The results showed that the thermal sensation of the sports crowd would be affected by the indoor thermal environment.With the increase of exercise intensity,the thermal sensation of the sports crowd would be less affected by the thermal environment.With the increase of the intensity of the movement,the upper and lower limits of the acceptable temperature show a tendency of decreasing.At the same time,with the increase of exercise intensity,the range of acceptable temperature will decrease.
