Subway station air-conditioning system

Abstract

The invention discloses a subway station air-conditioning system. The subway station air-conditioning system comprises a first air-conditioning system and a second air-conditioning system, wherein thefirst air-conditioning system is responsible for cooling loads at the near end of the station; the second air-conditioning system is responsible for cooling loads at the far end of the station; and the first air-conditioning system and the second air-conditioning system are independent of each other, and the first air-conditioning system and the second air-conditioning system are arranged at thesame end of the station. The air-conditioning systems adopt a single-end arrangement form, and the two sets of independent air-conditioning systems are correspondingly responsible for the cooling loads of near-end and far-end station public areas, so that pipelines are divided, the arrangement of the pipelines is more flexible and simpler, the height of a station layer does not need to be increased, and the equipment maintenance difficulty is reduced; and meanwhile, the first air-conditioning system and the second air-conditioning system are smaller in air supply and exhaust resistance, the distribution power of equipment is obviously reduced, the situation of air volume attenuation does not exist, and the energy-saving effect is remarkable.

Description

technical field [0001] The invention is used in the field of subway engineering, and in particular relates to an air-conditioning system of a subway station. Background technique [0002] As the subway project blossoms all over the country, in places with a large passenger flow in central cities, large marshalling trains will be used for the backbone lines in the city to solve the problem of large passenger flow transportation. With this is the continuous lengthening of the station length. For subway stations using 6A marshalling stations, the effective platform length reaches about 140 meters; for subway stations using 8A marshalling stations, the effective platform length reaches about 186 meters. For the station platform floor with wiring terminals, due to wiring restrictions, there will be fewer equipment rooms, and more equipment rooms will be placed on the station hall floor. At this time, the distance from the environmental control computer room to the effective pla...

Problems solved by technology

[0003] The distance from the environmental control computer room to the effective platform end may have reached a station that is greater than 0.5 times the train length. The use of double-ended air supply for the air conditioning system in the public area will cause the pipeline from the environmental control computer room at the large end of the equipment to the station hall and platform to be too long, causing energy consumption Increased situation

And because there are a lot of equipment rooms on the station hall floor at this time, the pipeline layout in the equipment management room area will be more complicated, and there are many intersections between the large system pipelines and the management room area, so it is necessary to increase the floor height, or repair and maintain difficult question
