Comfort evaluation of cabin environment in commercial aircrafts

Temperature, air quality and noise are the top 3 dissatisfied factors in current cabin environment. Studies the interaction of three factors by the combination of objective parameter measurements and subjective questionnaires. By controlling the single variable, creates temperature field, concentration field and noise field in real cruise. Evaluates the volunteers’ satisfaction with the cabin environment in each condition. The results show that when the indoor carbon dioxide concentration and the noise level increases, the volunteers feel warmer. The data of satisfaction percentages show that noise, air quality and temperature interact with each other, and noise is the most dissatisfied factor among three factors.
