To operate a railway vehicle air conditioner, following an operation pattern created to consider resonance and efficiency while securing a necessary cooling capacity during both a sound operation and a failed operation of an inverter device.SOLUTION: A railway vehicle air conditioner 11 comprises an outdoor blower 22, first and second compressors 23, 24, and first to third inverter devices 41-43 to drive the blower and compressors. The first inverter device 41 drives the outdoor blower 22 when the first inverter device 41 is sound, and the outdoor blower 22 and the first compressor 23 are inverter-driven by the second inverter device 42 when the inverter is failed. During both a sound operation and a failed operation, the first to third inverter devices 41-43 are controlled to follow an operation pattern determined based on an air conditioning capacity, a vehicle body resonance frequency and an energy efficiency.SELECTED DRAWING: Figure 1

    【課題】インバータ装置の健全時と故障時の双方において、必要冷房能力を確保しつつ、共振および効率を考慮した運転パターンにより運転する。【解決手段】鉄道車両用空気調和装置11は、室外送風機22、第1と第2の圧縮機23,24、これらを駆動する第1〜第3のインバータ装置41〜43を備える。第1のインバータ装置41の健全時には、第1のインバータ装置41で室外送風機22を駆動し、故障時には、第2のインバータ装置42により室外送風機22と第1の圧縮機23とをインバータ駆動する。健全時と故障時、それぞれ、空調能力と車体の共振周波数とエネルギ効率とに基づいて定められた運転パターンに基づいて、第1から第3のインバータ装置41〜43を制御する。【選択図】図1
