The Study of Air Supply Ways Effects on the Aircraft Cabin Thermal Environment

Abstract

The purpose of this study is to fully understand the effects of air supply positions and angles on the cabin thermal environment and improve the thermal environment quality. Firstly, the cabin model is established based on the Boeing 737 cabin structure and the grid independence is verified, which proves that the number of grids no longer affects the simulation results and the result has high credibility. On this basis, PMV-PPD values, temperature non-uniformity indices and the velocity non-uniformity indices under different air supply positions and angles in the cabin are compared and analyzed. Finally, the relationship between air supply ways and thermal comfort is obtained. The simulation results provide theoretical basis for the optimization of airflow distribution in aircraft cabin, and ultimately achieve optimal thermal comfort and energy-saving.
