Description
Technical field
The utility model relates to subway split-type air conditioner technical field, relates in particular to an one-driven-many indoor air-conditioning unit for a kind of subway station.
Background technology
Subway is long and narrow hypogee, except each station entrance-exit, supply and exhaust mouth communicate with the external world, substantially be hedged off from the outer world, subway can produce a large amount of heats and be brought into station in running, stratum has accumulation of heat effect, along with the time of operation increases, the temperature of subway system inside can raise year by year, crowd intensive flow make stuffy, there is these features just because of subway, so subway needs environmental control system guarantee to have in subway suitable temperature, humidity and certain comfortableness condition is provided. Along with social development and scientific and technological progress, traditional subway ventilation air-conditioning system can not adapt to the coordinated development of subway construction and urban environment.
