The Design of Airduct in Type A Car Air Conditioning System

介绍了地铁车辆空调风道设计的特殊性及国内地铁A型车空调的风道设计方法。利用静压腔原理设计的地铁A型车空调的送风道有效地解决了气流分配问题。并对主风道送风均匀性和客室内的气流分布进行了模拟。分析了地铁A型车空调系统风道在风量分配、均匀送风方面的优缺点,提出了在保温和消除噪声方面的措施。

This paper introduces the designing particularity of airduct in the subway air-conditioning and the design method of airduct in domestic A-type air-conditioning system. Because the air volume distribution is to be done reasonably through the air - conditioning structure design, the uniformity of the air supply in the main airduct and the air distribution in the compartment are simulated. This paper also analyses the advantages and disadvantages of the air volume distribution and the air supply uniformity of A - type car airduct in domestic subway, discusses measures of metro car insulation and noise elimination.
