摘要:

将主观问卷调查与生理指标测试相结合进行了实验研究,分析了不同风速条件下生理指标和主观评价指标的变化特征,分别建立了风速与生理指标及生理指标与主观评价指标的预测模型,以实现对生理指标和主观评价指标的预测。研究结果显示:在不同风速条件下,仅有皮肤温度与皮肤导热热流量存在显著性关联,且均随风速的增大呈降低趋势,心率与心率变异性的变化并不明显;在设定的热环境条件下,受试者能够接受的风速范围为0.150.35 m/s,感觉中性的风速为0.3 m/s

Abstract:

Carries out an experimental study combining the subjective questionnaire survey with the physiological index test, and analyses the variation characteristics of physiological indexes and subjective evaluation indexes under different wind speed conditions. Establishes the model of wind speed and physiological indexes and the model of physiological indexes and subjective evaluation indexes respectively and predicts these indexes. The research results show that under different wind speed conditions only skin temperature closely associates with skin heat conduction flux and decreases with the increase of wind speed, and the changes of heart rate and the variability are not obvious. Under the established thermal environment conditions, the acceptable wind speed range of the respondents is 0.15 to 0.35 m/s, and the neutral wind speed is 0.3 m/s.

Keywords:windspeed,thermalcomfort,skintemperature,skinheatconductionflux,thermalsensation,draftsensation,physiologicalindex,subjectiveevaluationindex
