驾乘舱非均匀热环境中人体热生理响应与主观热感觉相关性分析

Analysis on the Correlation Between Human Physiological Thermal Responses and Subjective Thermal Sensation in Inhomogeneous Thermal Environment of Passenger Compartment

明确乘员生理热响应与热感觉相关性是实现舱内热环境智能化控制的迫切需求。为探究人体热感觉与其生理热调节的关系,搭建了非均匀热流耦合的乘员舱气候试验平台,进行主观热感觉评分,通过热感觉和热舒适试验建立双标尺的人体热感觉评价体系,接着,通过受试者穿戴传感器,测得脉率、血氧饱和度、血压和皮肤温度等生理热响应。对试验数据进行处理和分析,T检验数值表明,脉率及其变化率与热感觉呈显著正相关(Pearson相关系数分别为0.943和0.955),而血压的平均压变化率和舒张压变化率与主观热感觉呈显著负相关(Pearson相关系数分别为-0.955和-0.948)。

Clarifying the correlation between occupants′ physiological thermal response and thermal sensation is the imperative requirements for achieving the intelligent control of compartment thermal environment. In order to investigate the relationship between human thermal sensation and physiological thermal regulation,a passenger compartment climate test platform is constructed,a subjective thermal sensation evaluation is conducted,and a two-scale evaluation system for human thermal sensation is established through thermal sensation and thermal comfort tests. Then the physiological thermal responses including pulse rate,oxygen saturation of blood,blood pressure and skin temperature etc. are measured by the sensors the testees wear. The test data are processed and analyzed and the T check values indicate that the pulse rate and its changing rate show significant positive correlation with subjective thermal sensation with the Pearson correlation coefficient of 0.943 and 0.955 respectively;while the changing rate of mean arterial pressure and the changing rate of diastole pressure exhibit apparent negative correlation with subjective thermal sensation with the Pearson correlation coefficient of-0.955 and-0.948 respectively.
