| 摘 要： | 气流紊动特性是影响建筑热环境和人体舒适性的重要因素之一。该文从气流紊动特性对人体热舒适的影响和气流紊动特性的物理结构两个方面总结了建筑气流紊动特性的研究进展,其中重点介绍了清华大学在此方面的研究成果。综述表明,气流紊动特性对热舒适的研究目前主要还集中在湍流度和脉动频率两个参数上;自然风和机械风的气流紊动特性有着明显区别和联系,其机理有待于进一步研究。

| Abstract: | Airflow fluctuations are one important factor influencing building thermal environments and human thermal comfort. The research on the effects of airflow fluctuations in building environments is reviewed in this paper as two topics: the influence of the airflow fluctuations on the thermal comfort and the physical structure of the airflow fluctuations. The review emphasizes the research work at Tsinghua University. The research on the influence of airflow fluctuations on thermal comfort mainly focuses on the effects of turbulence intensity and fluctuation frequency. The fluctuating characteristics of natural and mechanically induced wind currents have obvious differences but are related, and these mechanisms need further study. |
