To provide an air conditioner which hardly disturbs air conditioning before and after a specific section in which indoor temperature easily fluctuates, and a method for controlling an air conditioner.SOLUTION: An air conditioner 1 includes a compressor, a condenser, an expansion valve 30 and an evaporator, and includes a refrigerant circuit part for performing air conditioning of the interior of a railroad vehicle, a position identification part 56 for periodically determining the position of the railroad vehicle within a route, an overheat degree information acquisition part 57 for periodically acquiring overheat degree information of refrigerant in the evaporator, and an expansion valve control part 58 for controlling the opening of the expansion valve 30 to be a constant opening in the case that the position determined by the position identification part 56 is determined to be a start point of a specific section in which indoor temperature easily changes, and changing the constant opening of the expansion valve 30 from the constant opening to an opening based on the overheat degree information of the refrigerant acquired by the overheat degree information acquisition part 57 in the case that it is determined to be an end point of the position identification section determined by the position identification part 56.SELECTED DRAWING: Figure 5

    【課題】室内温度が変動しやすい特定区間の前後で空気調和が乱れにくい空気調和機および空気調和機の制御方法を提供する。【解決手段】空気調和機1は、圧縮機、凝縮器、膨張弁30および蒸発器を備え、鉄道車両の室内を空気調和する冷媒回路部と、鉄道車両の路線内での位置を周期的に特定する位置特定部56と、蒸発器での冷媒の過熱度情報を周期的に取得する過熱度情報取得部57と、位置特定部56が特定した位置が、室内温度が変動しやすい特定区間の開始点であると判定した場合に、膨張弁30の開度を一定の開度にし、位置特定部56が特定した位置特定区間の終了点であると判定した場合に、膨張弁30の開度を一定の開度から過熱度情報取得部57が取得した冷媒の過熱度情報に基づいた開度へ変更する膨張弁制御部58と、を備える。【選択図】図5
