体育馆空调环境不仅会影响人体的运动效果、运动成绩,对于体育馆空调节能也有重要意义。相比于运动人员的热舒适性,传统的空调设计往往更多地关注观众的热舒适性。运动人体具有新陈代谢率大,衣着少,排汗量大以及呼吸急促的特点,传统的基于Fanger模型的人体热舒适性评价指标难以准确预测运动人体的热舒适性。本文针对运动人体提出了衣着覆盖率的概念,对Fanger模型中的辐射、体表扩散的模型进行适当的修正,并探讨了修正模型与Fanger模型计算结果差异。同时,采用环境测试仪和问卷调查对某高校体育馆内篮球训练类、健美操训练类和羽毛球健身类运动人体进行了大量实验调查,并将实验结果与两种模型计算结果进行对比和偏差分析,研究结果表明,修改模型PMV计算结果低于Fanger模型且更接近实测结果,这表明对于运动人体,适宜的场馆环境温度可以比采用Fanger模型得到的传统的空调温度更高,对于空调节能具有重要意义。
Gymnasium air conditioning environment will not only affect the human body’s exercise results, sports performance, energy saving for the stadium air conditioning is also important. In contrast to the thermal comfort of athletes, traditional air conditioning designs tend to focus more on the thermal comfort of the viewer. The moving human body has the characteristics of large metabolic rate, less clothes, perspiration volume and shortness of breath. The traditional human thermal comfort evaluation index based on the Fanger model can not accurately predict the thermal comfort of the moving body. In this paper, we put forward the concept of clothing coverage for the moving human body, and properly modify the model of radiation and surface diffusion in Fanger model, and discuss the differences between the revised model and the Fanger model. At the same time, a large number of experimental investigations were conducted on the basketball training class, aerobics training class and badminton fitness class human body in a college gymnasium by using environment tester and questionnaire survey. The experimental results were compared with the results of two models and the deviations were analyzed. The results show that the modified model PMV calculation results are lower than the Fanger model and closer to the measured results, indicating that for the human body, suitable venues ambient temperature can be higher than the traditional air-conditioning temperature obtained by the Fanger model is important for energy-saving air-conditioning .
