To provide an elevator shaft pressure fluctuation reduction system that is easy to install while reducing air flow between an elevator shaft and a room pressure management area.SOLUTION: An elevator shaft pressure fluctuation reduction system comprises an air blower 21 provided on an elevator car 5 and capable of rotating in normal and reverse directions, a guide duct 22 provided on the elevator car 5 and capable of guiding the flow of air between an upper side Y1 of the elevator car 5 and a lower side Y2 of the elevator car 5 in an elevator shaft 4, and a control unit 23 that controls the air blower 21, and the control unit 23 controls the air blower 21 so as to rotate the air blower 21 in one direction to deliver the air at the upper side Y1 of the elevator car 5 to the lower side Y2 of the elevator car 5 through the guide duct 22 when the elevator car 5 ascends and so as to rotate the air blower 21 in the reverse direction to deliver the air at the lower side Y2 of the elevator car 5 to the upper side Y1 of the elevator car 5 through the guide duct 22 when the elevator car 5 descends.SELECTED DRAWING: Figure 1

    【課題】エレベータシャフトと室圧管理エリアとの間での空気の流動を抑えながら設置し易いエレベータシャフト用の圧力変動抑制システムを提供する。【解決手段】エレベータカゴ5に備え付けられた正逆回転可能な送風機21と、エレベータカゴ5に備え付けられてエレベータシャフト4内においてエレベータカゴ5の上方側Y1とエレベータカゴ5の下方側Y2との間で空気を流動案内可能な案内ダクト22と、送風機21を制御する制御部23とを備え、制御部23が、エレベータカゴ5の上昇時はエレベータカゴ5の上方側Y1の空気を案内ダクト22を通してエレベータカゴ5の下方側Y2に送るべく送風機21を一方向に回転させ、エレベータカゴ5の下降時はエレベータカゴ5の下方側Y2の空気を案内ダクト22を通してエレベータカゴ5の上方側Y1に送るべく送風機21を他方向に回転させるように送風機21を制御する。【選択図】図1
