UNDERGROUND STATION AIR CONDITIONING METHOD AND UNDERGROUND STATION AIR CONDITIONING SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce an air conditioning load at underground station under effective utilization of low enthalpy train wind left in the prior art without giving any trouble to safety in vehicle transportation.SOLUTION: This invention relates to an air conditioning system for underground station where platform door devices 1, 2 are installed. Louvers 21 acting as opening or closing member that can be opened or closed are arranged at opening parts 13 above spandrel walls 6, 7 parting a platform 3 and railway segments 4. When cooling operation is being carried out and enthalpy of tunnel air is lower than enthalpy of a space at the platform 3, blades 21a of the louvers 21 are released to feed positively train wind accompanied by its running onto the platform 3 and in turn when enthalpy of tunnel air is higher than that of the platform, the blades 21a of the louvers 21 are closed to restrict the flowing-in of the train wind into the space of the platform 3.
