Abstract: At present, energy saving, consumption reduction and green development are the development road actively explored by subway operation units. Based on the good climatic conditions of Guiyang City, as well as the passenger flow characteristics of Guiyang Metro Line 1 and 2, this paper carries out the research on the energy-saving operation of the ventilation and air-conditioning system in the public area of the station, and selects 25 stations as pilot projects to carry out practical demonstration. The data show that the energy-saving operation scheme of ventilation and air-conditioning system in the public area of the station is feasible, and the purpose of energy saving, emission reduction, cost reduction and efficiency can be achieved under the premise of ensuring the quality of waiting environment.
Keywords: subway; ventilation and air conditioning; energy saving and consumption reduction; emission reduction; cost reduction and efficiency improvement
地鐵作為一種大運量公共交通系統,其運營能耗給運營企業帶來了巨大的運營成本和經濟壓力。由于地鐵的公益屬性,決定其自身運營收支難以相抵,節能降耗、綠色發展成為了所有運營企業的共識,各運營企業十分重視節能降耗技術的探索及應用,以期減少用電成本。在貴陽地鐵能耗體系中,列車牽引、車站動力照明是最主要的能耗部分,地鐵1、2號線車站動力照明能耗占運營總能耗的50%~60%,車站公共區通風空調系統作為車站動力照明能耗占比較大的設備,基于貴陽市優勢氣候條件及客流特點,開展地下車站公共區通風空調系統節能運行研究具有重大現實意義[1]。
