湿热地区过渡季体育训练馆中运动人群的热环境倾向研究

Study on the Thermal Comfort of the Sports Crowd in the Sports Training Center in Transitional Season in Hot and Humid Area

在我国湿热地区,大多数体育建筑被设计成全空调模式,用机械通风来调节建筑的热环境,能源消耗量巨大。本文通过对湿热地区的典型多层叠合的体育训练馆进行实测调研,采取热环境物理量和问卷调查相结合的方式,分别建立了温度倾向、气流倾向与操作温度的线性关系。研究结果显示,不同的运动状态对运动场内的热环境倾向是不一样的。随着运动强度的增加,运动人群所感受到的最合适的温度会逐渐降低。随着操作温度的增加,对希望降低温度的投票比例越来越大,对希望加快气流的投票比例也越来越大,并且运动人群对增加气流速度的期望要高于降低温度的期望。

In hot and humid areas of China,most of the sports buildings are designed with a fully air-conditioned mode,which uses mechanical ventilation to adjust the thermal environment of the buildings and consumes a lot of energies.In this paper,the linear relationship between temperature trend,airflow trend and operating temperature is established by means of the combination of physical quantity of thermal environment and questionnaire survey.The results show that different motion states have different requirements for the thermal environment in the stadium.As the intensity of the exercise increases,the optimum temperature experienced by the exercisers will gradually decrease.As the operating temperature increases,there are more and more votes requiring to lower the temperature or accelerate the airflow.Moreover,people’s expectation of air velocity increase is higher than that of temperature decrease.
