中文摘要： 航天员在失重环境中受力情况发生改变，由此继发的人体生理适应性变化导致人体生理热调节过程发生改变，故其热舒适状态与建筑环境热舒适性存在显著差异。本项研究瞄准影响人体热舒适的几种关键因素，针对失重条件下密闭环境内人体生理变化的特点，借助人体生理学、传热传质学、计算流体力学等相关理论研究失重条件下人体生理热反应与人体热舒适性，分析航天员在失重条件下人体生理变化及人体生理热调节机理，建立失重条件下人体生理热调节模型；应用人体生理热调节模型与CFD技术耦合计算方法，根据热平衡规律，掌握温度、风速、湿度和辐射等参数对人体热舒适的影响规律，明晰人体与环境之间的换热过程；探讨传统热舒适指标在失重条件下密闭环境的适用性，深化对失重条件下人体热舒适机理的认识，提出失重条件下密闭环境内人体热舒适评价指标和方法。本项目研究对丰富和完善人体热舒适性理论，保护航天员生命健康和提高人机功效具有重要的意义。

英文摘要： Human physiology is changed in weightlessness environment, which lead to physiology thermoregulation changed.There are significant differences between weightlessness environment to build environment for thermal comfort. This research aimed at several key factors which affecting human body thermal comfort and contraposed the characteristic of the change on human physiology in weightlessness hermetic environment. Using physiology, heat and mass transfer and computational fluid dynamics, physiology thermoregulation and thermal comfort are researched in weightlessness environment. The effect of weightlessness environment on physiology thermoregulation are studied, and the model of physiology thermoregulation in weightlessness environment is founded. The effect of temperature, air velocity, humidity and radiation on thermal comfort are discovered by simulation method of coupled thermoregulation model and CFD model. Understanding the process that the human body having thermal response on weightlessness environment and the thermoregulation discipline deeply. The tradition thermal comfort indexs are discussed in weightlessness environment, thermal comfort mechanism are further researched. The thermal comfort index in weightlessness environment is proposed. This study can be abundant and improved the thermal comfort the
