【摘要】：热环境过渡通常伴随着环境温度的突变,人们在不同环境过渡时其热感觉也会随之变化。对热环境过渡过程中人体热生理和热心理变化规律进行研究,合理预测动态过程中人体的热感觉,对于舒适健康高效节能的热环境的人工营造及自然气候要素的被动利用具有十分重要的现实意义。为了探究在不同热环境中过渡时人体热生理和热心理的变化规律,分析不同过渡空间中人体热舒适情况及经过不同过渡空间对人体热感觉变化的影响,为不同过渡空间的工程设计提供理论依据和指导,本文针对热环境过渡过程中人体热反应变化规律及不同过渡空间的热舒适情况进行了现场调查研究。本文以株洲某商场为研究对象来研究热环境过渡过程中人体热生理和热心理的变化规律及不同过渡空间的热舒适情况。本文首先以两种不同的过渡空间(一个有空调,一个没有空调)为研究对象,在对该商场实地测试和问卷调查的基础上,得到了两种过渡空间的热舒适情况及两者的差异。其次本文通过对20名在校研究生进行的跟踪调查研究了受试者在热环境过渡过程中人体热心理和热生理的变化规律、皮肤温度及其变化率与热感觉变化的关系,并比较了经过不同过渡空间对人体热感觉变化的不同影响。通过实地测试、问卷调查、跟踪测试以及对数据的统计分析得出:不同的过渡空间设计对环境的热舒适性会有不同的影响。冬季在商场的过渡空间使用空调可以加速人体皮肤温度的升高及加大皮肤温度的变化幅度,使人进入室内后的皮肤温度能尽快的恢复到舒适水平;而夏季在商场的过渡空间是否使用空调对其热舒适性及对受试者进入室内后皮肤温度的变化影响都比较小。另一方面,在对整个热环境过渡过程中环境温度、皮肤温度和皮肤温度变化率与人体热感觉之间的关系的研究表明:环境温度是热感觉的主要影响因素之一,与人体热感觉有很明显的相关性;但热感觉与皮肤温度的相关性并不明显,即在动态变换的环境中,平均皮肤温度不能单独用来评价人体热舒适性,也不能直接用来预测动态环境中的热感觉;在热环境过渡过程中热感觉与皮肤温度及其变化率相关性明显,可以用皮肤温度及其变化率评价热环境过渡过程中人体的热感觉。最后,本文通过对实验数据的统计分析建立了热环境过渡过程中人体热感觉的预测模型,本文的研究结果将为动态热环境的热舒适研究及不同过渡空间的工程设计提供理论基础和依据。
[Abstract]:The thermal environment transition is usually accompanied by the sudden change of the ambient temperature, and the thermal sensation of the human body will change with the transition of different environment. The changes of thermal physiology and thermal psychology of human body during the transition of thermal environment are studied. Reasonably predict the thermal sensation of the human body during the dynamic process, It has very important practical significance for the artificial construction of comfortable, healthy, efficient and energy saving thermal environment and the passive utilization of natural climate elements. In order to explore the changing law of human body's thermal physiology and psychology during the transition in different thermal environment, This paper analyzes the thermal comfort of human body in different transition space and the influence of different transition space on the change of thermal sensation of human body, and provides theoretical basis and guidance for the engineering design of different transition space. In this paper, the changes of human body's thermal reaction and the thermal comfort of different transition spaces are investigated in the process of thermal environment transition. A shopping mall in Zhuzhou is taken as the research object to study the human body in the process of thermal environment transition. The changes of thermal physiology and thermal psychology and the thermal comfort of different transition spaces. In this paper, two different transition spaces (one with air conditioning, one with air conditioning, One without air conditioning) was studied on the basis of field tests and questionnaires in the mall. The thermal comfort of the two transition spaces and the differences between them were obtained. Secondly, the changes of thermal psychology and physiology of the subjects during the transition of thermal environment were studied through a follow-up investigation of 20 graduate students. The relationship between skin temperature and its rate of change and the change of thermal sensation, and the effects of different transition space on the change of thermal sensation were compared. Tracking test and statistical analysis of the data show that different design of transition space will have different effects on thermal comfort of the environment. The use of air conditioning in the transition space of shopping malls in winter can accelerate the increase of skin temperature of human body; Increase the range of skin temperature, The skin temperature after entering the room can recover to comfortable level as soon as possible. However, whether air conditioning is used in the transition space in the shopping mall in summer has little effect on the thermal comfort of the person and the change of the skin temperature after the subjects enter the room. On the other hand, The study on the relationship between environmental temperature, skin temperature and skin temperature change rate and human body thermal sensation during the whole thermal environment transition process shows that environmental temperature is one of the main influencing factors of thermal sensation. There is a clear correlation between the thermal sensation and the skin temperature, but the correlation between the thermal sensation and the skin temperature is not obvious, that is, in the dynamic environment, the average skin temperature can not be used to evaluate the thermal comfort of the human body alone. It can not be directly used to predict the thermal sensation in dynamic environment. During the process of thermal environment transition, there is a significant correlation between thermal sensation and skin temperature and its rate of change. The skin temperature and its change rate can be used to evaluate the human body's thermal sensation during the thermal environment transition. Finally, the prediction model of the human body's thermal sensation during the thermal environment transition is established by statistical analysis of the experimental data. The results of this paper will provide a theoretical basis for the study of thermal comfort in dynamic thermal environment and the engineering design of different transition spaces.
