摘要
老年人由于感知和调节能力的衰退,更容易受到室内环境变化的影响,甚至健康和生命也会受到威胁。要为老年人提供一个健康舒适的室内环境的第一步就是准确评价老年人的热舒适状况。通过引入老年人热舒适模型,结合文献综述,并基于胸足温差生理参数,对中国老年人的热舒适评价进行了探索,结果表明:评价室内热环境时,不能仅局限于老年人的主观评价,还应结合生理等客观参数进行评价。基于该研究,夏季室温在热中性温度附近时,老年人的胸足温差一般处于1.0—1.5℃之间。
Old people are more vulnerable to thermal-related comforts and health issues because of their weakening abilities to perceive and adapt to ambient thermal environment. It calls for building a healthy and comfortable indoor environment for the elderly, thus it＇s essential to accurately evaluate the thermal comfort of the older people. Some research on thermal comfort evaluation of the elderly was done based on thermoregulation model, literature review and the skin temperature difference between the thorax and foot. The result indicates not only the subjective evaluation but also the objective parameters are necessary to the evaluation of the indoor environment. According to our research, skin temperature difference between the thorax and foot of the Chinese elderly were generally between 1.0 to 1.5 ~C when indoor temperature in the summer near the thermal neutral temperature range.
