Design and Optimization of Air Supply System to Satisfy the Thermal Comfort of Human Body

Abstract

In view of this problem that the existing cockpit air supply system cannot meet the thermal comfort requirement of human body, causes the physical/psychological discomfort of pilots, and affects the work efficiency and safety of pilots, the design and optimization of the cockpit air supply system is studied to satisfy the thermal comfort of human body, in this paper. Firstly, a standard two-equation turbulence model is used to simulate the thermal environment of the cockpit in a large airliner under the original air supply system. It is concluded that the original air supply scheme does not meet the thermal comfort requirements of pilots. Secondly, the air supply condition of the cockpit air supply system is optimized and improved, and 18 optimization schemes are proposed. Finally, each optimization scheme is evaluated to obtain the optimal scheme which can satisfy the thermal comfort of human body. The design and optimization method of the air supply system established in this paper can be used in the study of thermal comfort and the design of the air supply system in the cockpit of large airliners.
