变压力环境下人体热感觉的实验研究

Experimental studies of human thermal sensation in variable pressure environment

利用高原低气压气候模拟舱模拟不同压力环境,着重研究0.8～1.0atm范围内压力变化对人体热感觉的影响,主要从压力的升降方面对热感觉进行对比分析.通过对100名受试者在不同压力环境下热感觉投票值的调查,发现随着压力的降低,热感觉投票值下降,人体感觉越凉;在压力回升的过程中,热感觉投票值上升,人体感觉越暖,结合升降压过程,发现在经历降压过程再回升至常压时,人体热感觉存在滞后.探讨了人体热感觉在升降压过程中的变化,为进一步改善因气压环境变化引起的不舒适提供理论基础,同时也为空调系统设计提供依据。

With a simulation cabin simulate different pressure environment used,this paper focuses on the effects of 0.8-1.0atm pressure change on human thermal sensation,and analyzes thermal sensation from the aspects of the rise and fall of pressure.Based on the survey of 100participants＇ thermal sensation vote value under different pressure environment,it finds that the reduction of pressure thermal sensation vote value decreases,and the body feels more cool;in the pressure recovery process,thermal sensation vote value rises,the body feels more warm.Combined with the pressure of lifting process,it finds that human thermal sensation lags behind as the environment through decompression process goes back to normal pressure.So it discusses the human thermal sensation in the process of pressure changes,in order to improve theoretical basis on pressure environment,and the air conditioning system design.
