被服系统热舒适性研究进展

Research progress on thermal comfort of bedding system

被服系统作为调节人体睡眠舒适性必不可少的产品,比室内环境对睡眠热舒适性的影响更大。为合理评价被服系统的热舒适性能,通过回顾国内外相关研究,从实验研究和舒适性模型研究的角度总结睡眠热舒适性研究中常用的评价方法;基于“人体—被服—环境”系统热湿交换理论,从被服系统热阻、湿阻、被内微气候等被服因素,人体热生理、性别和工作状态差异性等人体因素,环境温度、湿度、风速等环境因素3个角度分析了各类因素对睡眠热舒适性的具体影响;剖析当前研究中的不足和缺陷,展望被服系统睡眠热舒适性的研究趋势。提出建立普遍适用的“人体—被服—环境”系统舒适性模型,以提高对睡眠热舒适性评价的准确性。

As a necessary part during sleeping,the bedding system has more pronounced effect on sleeping thermal comfort than the indoor environment.To properly evaluate the sleeping thermal comfort of the bedding system,commonly used evaluation methods were reviewed in terms of experimental research and numerical modeling studies worldwide.Based on the heat and moisture exchange theory of human-bedding system-environment system,various influencing factors for sleeping thermal comfort were analyzed in three aspects,i.e.bedding system factors such as thermal resistance,evaporative resistance and bedding microclimate,human body factors such as thermal physiological differences in gender and working status.Environmental factors such as environmental temperature,humidity and speed of wind were also investigated for their effects on the sleeping thermal comfort.The drawbacks of current studies were pointed out and the development trends of sleeping thermal comfort of bedding systems were predicted.A comprehensive″human-bedding system-environment″thermal comfort model was proposed to improve the accuracy of sleeping thermal comfort evaluation.
