Field Measurement and Numerical Simulation of Air Infiltration from Entrances in an Airport in Winter

Publication Date

Abstract

In the large spaces of airport terminals, such as the check-in hall and arriving hall, there are many entrances. The air infiltration from entrances has a great influence on the indoor environment, which should be paid high attention. In this paper, on-site measurement of the indoor environment is conducted in an airport terminal, which is located in the hot summer and cold winter zone, in winter. The field test results show that the air infiltration rate on the first floor is obviously larger than that on the second floor, which leads to lower temperatures and a higher heating load on the first floor. On the basis of this, a numerical model is built with Airpak and verified by comparing with the measured data. According to the simulation results, adopting an air curtain can help reduce the influence of air infiltration and improve indoor thermal comfort in winter.
