Modelling the impact of aircraft cabin pressure and humidity on thermal comfort

摘要

In aircraft cabins during cruise conditions at high altitude, common operative values for cabin pressure and relative humidity are significantly lower than those at sea level. In this paper, the impact of cabin pressure and humidity on thermal comfort is investigated using a physics-based multi-node human thermoregulation model. The objective of developing an enhanced thermoregulation model is to support the envelope determination of environmental cabin parameters for maximum occupant well-being. Enhancements to the thermoregulation model to account for variable ambient pressure and humidity are described and applications of the model are shown. It is concluded that, within the normal operative range of aircraft cabin pressure and humidity, their impact on thermal comfort of passengers is limited.
