摘要
SUMMARY: In this paper, the environmental parameters in airliner cabin of China are investigated through thefield study and questionnaire survey in 8 domestic flights. The measured parameters include temperature, relativehumidity, wind speed, cabin pressure and the concentrations of carbon dioxide, carbon monoxide, sulfur dioxide,nitrogen dioxide, ozone, TVOCs, formaldehyde and microorganisms. Through the questionnaire involving 37passengers, the subject subjective votes of the environment are investigated.The thermal environment, humidsensation, draughts, air quality, odor and the chief complaints of discomfort symptomsare concerned. The resultsof the investigation show thatin the airliner cabin the air temperature in wintertime is too high, the relativehumidity is a little lower, while the concentrations of carbon dioxide and TVOCs are higher than the specifiedvalues in the codes. It also shows that all the parameters except for temperature are in the limited ranges stipulatedin the relevant design codes for aircraft. According to the questionnaire survey, the rank of the environmentalfactors, which affect the overall degree of satisfaction, is noise, air quality, temperature, cabin pressure, relativehumidity, and vibration.
