Research on Subway Air-Conditioning System Design

Abstract:

The design of subway air-conditioning system accounts for not only the general characteristic, but also the following factors the different working circumstances and the big passengers density. In order to provide sufficient refrigerating capacity to offset the heat quantity of subway carriage, it is indispensable to install a reasonable air-conditioning, heating and aeration system to improve the comfort. In this paper the research object is the velocity and temperature change of the airflow inside the subway, and the research method is computer simulation. We study the performance and temperature change of the airflow using UG and CFD, compare and analyze the variation of the airflow in the same cross section of different models. Through comparing and analyzing the velocity and temperature change of the three models, this paper finds that the model that installs the inlets at the two sides of the subway is senior to that installs the inlets at the top of the vehicle.
