Preliminary exploration on air quality control and wholeness systemdesign of large multi-storey underground spaces

By analysing the specific situation of high humidity, easy condensation, and excessive concentration of harmful substances in the garages and the rapid public transportation areas of a large multi-storey underground space project, an air quality control strategy taking into account safety, comfort and energy saving is formulated. According to the actual use requirements and implementation conditions of the whole building, the wholeness systems such as the vacuum garbage unified collection system and the centralized cold and heat source system adapted to the above-ground building are presented. Based on the premise of meeting the use the function of the building, the design technical measures of air quality control and wholeness system of large multi-storey underground spaces are discussed.
