【摘要】：针对实际间歇空调运行情况的体现,依托某实际空调房间,基于人体进入空调房间之前热经历以及空调环境变化的随机测试工况,通过人体主要部位皮肤温度等生理参数和室内环境参数的测试以及人体热感觉和空调关闭意向的问卷调查,研究分析空调环境中处于静坐状态人体的生理热反应及其与空调关闭行为的相互关系.结果表明,在四肢和颈部几乎暴露于环境的条件下,空调环境中人体脚底皮肤温度变化明显,并对人体热感觉产生重要影响,伴随脚底皮肤温度的降低,人体热感觉从热中性开始,之后以"阶梯降"的形式逐步降低.同时,尽管空调关闭时的人体热感觉存在差异,但从统计角度分析,决定空调关闭动作产生的关键因素仍是脚底皮肤温度.脚底皮肤温度又最终由人体的环境暴露状况(热环境经历和当前所处环境)所决定,空调环境温度越低,人体对空调环境的热不可接受度越高,空调关闭的动作越容易发生.与脚底相对照,颈部、胸部、手背、大腿和前臂的皮肤温度对人体热感觉和空调关闭行为不产生统计上的显著影响.
[Abstract]:According to the actual situation of air conditioning of intermittent, relying on an actual air conditioning room, random test conditions into the air conditioning room before the body heat and air conditioning experience based on the change of physiological parameters, through the main parts of the human body skin temperature and indoor environment parameters testing and human thermal sensation and air conditioning closed questionnaire intention, research and analysis in each other the relationship between the physiological state of the human body in the thermal reaction and the air conditioning off behavior of air conditioning environment. The results show that in the limbs and neck almost exposed to environmental conditions, human foot skin temperature air conditioning environment changes obviously, and has an important effect on human thermal sensation, with reduced foot skin temperature and thermal sensation from the beginning hot neutral, to "step down" form gradually reduced. At the same time, despite differences in body heat air conditioning off the feeling, but from Statistical analysis, determine the key factors of the air conditioning off action is still the sole foot skin temperature and skin temperature. Finally by the human exposure to environmental conditions (thermal environment and the current environment) determined by the air conditioning temperature is low, the air conditioning heat body unacceptable degree is higher, the air conditioning off. Is more likely to happen. According to relative, the soles of the feet with the neck, chest, back, thighs and forearm skin temperature on human thermal sensation and air conditioning off do not have a significant impact on statistical behavior.

【正文快照】： 空调的目的在于满足人体对室内环境的热舒适需求,因此,人体对室内环境的生理热反应本质上决定着空调的开、关状况.在安装分体空调的居住建筑和带有三速开关风机盘管的办公建筑中,居住者对空调的开、关状况具有完全的控制权.人在室内或由室外进入到室内感到热时会开空调或加大
