Abstract:

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.
