Open publisher page 1 citations

Abstract

Based on the calculated cooling load of common area in the subway station,the hourly ventilation rate could be determined.Combined with the design plan of 1# line of Tianjin Subway,the year-round frequency control strategy for the fan was put forward.In addition,using the CFD technology and Airpak software,the velocity and temperature fields under the VAV-based operation mode in the common area in summer were simulated.Finally,it was found out that the related results could satisfy the design requests.
