区域适应性地铁通风空调系统研究

地铁作为高效安全的交通工具,在全国各个气候区广泛应用。根据我国5个不同气候区的气候特点,分别论述各个气候区应采用的地铁通风空调系统制式。针对每个气候区,以其代表城市为例,详细论述系统的设置形式及节能优势。综合得出:严寒地区和温和地区可以取消活塞风道,车站公共区应采用通风系统形式,严寒地区可采用集成通风系统+可调门形式;寒冷地区、夏热冬冷地区及夏热冬暖地区应设置空调系统,其中寒冷地区和夏热冬冷地区可采用集成闭式系统及全封闭站台门系统,夏热冬暖地区应采用全封闭站台门系统。除温和地区之外,其他4个气候区可结合可调通风型站台门的设置进行空调季节与非空调季节的模式转换,在单一模式中实现最优控制,从而达到全年节能运行的目的。

Regional Adaptive Subway Ventilation and Air Conditioning System

As an efficient and safe means of transportation, subways have been widely used in various climatic zones in China. According to the climatic characteristics of five different climatic zones in China, this paper discusses the metro ventilation and air conditioning systems that should be adopted in each zone. Taking a representative city as an example of each climatic region, the setting form and energy-saving advantages of the system are discussed in detail. It is concluded that the piston duct can be canceled and public areas of the stations shall adopt the form of a ventilation system in a severely cold and mild area. Integrated ventilation systems and adjustable doors are adopted as the best forms in severely cold areas. Air conditioning systems should be installed in cold areas, areas with hot summers and cold winters, and areas with hot summers and warm winters. The integrated closed system and fully closed platform door system can be used in cold areas and areas with hot summers and cold winters. A fully closed platform door system should be used in areas with hot summers and warm winters. In addition to temperate areas, the ventilation and air conditioning systems in the common areas of the stations in the other four climate areas can be setting with the adjustable ventilation platform doors for the conversion of air conditioning and non-air conditioning seasons. Optimal control is realized in a single-mode to achieve the goal of energy-saving operation throughout the year.
