热压通风建筑的风路设计与风场模拟

Design and Simulation of Buoyancy-driven Ventilation System in Buildings

本文运用理想气体公式结合经验修正对中国矿业大学某实验楼改造进行了热压通风设计,建立了热压通风单元的流体动力学模型并模拟了一定环境下的室内服务区域和各进出气口的风速分布及温度分布。模拟结果合理地反映了通风设计情况,有助于方案的确定。

In this paper, based on the ideal gas formula combined with empirical corrections, the design of buoyancy -driven ventilation system was carried out for the key laboratory retrofit project in China University of Mining and Technology, the fluid dynamic model for the ventilation unit was established, and the velocity and temperature distributions in internal service areas and each inlet and outlet were simulated. The results indicated that the reasonable design of ventilation system would be helpful for the determination of the scheme.
