地铁公共区空调系统风管流量调节特性测试分析

Analysis Based on Testing of the Duct Flow Characteristics of Air-conditioning System in Public Areas of Subway

地铁公共区间空调系统风管风量能否达到设计的要求,将严重影响地铁公共区间内部空间的空调环境的舒适性。这使得地铁空调风管的流量分配调节显得尤为重要。通过对风管流量特性的分析,结合实验测试数据,研究一种合理的三通流量调节装置,从而保证地铁公共区间的站厅层和站台层风量的分配,达到预定的风量调节。

Whether or not an air-conditioning system in public area of subway meeting the design requirements is an important issue,which will seriously affect the comfort of air-conditioning environment in public areas of subway,so the air volume distribution of air duct in subway air-conditioning system is particularly important.Based on the analysis of air volume characteristics,combining the experimental date,a reasonable three-way valves for flow controlling was developed,which can ensure the distribution of air volume in public areas and achieve the desired adjustment of air volume.
