To provide a monitoring system capable of appropriately monitoring easiness of increase of an inverter device's temperature caused by driving an electric motor of a fluid machine.SOLUTION: A monitoring system performs monitoring operation on an inverter device for performing power conversion operation of drive power of an electric motor in a fluid machine using a switching element. The monitoring operation is operation of: monitoring specific information having correlation with easiness of increase of the inverter device's temperature caused by driving the electric motor; and determining whether or not the easiness of increase of the temperature has reached a predetermined reference condition.SELECTED DRAWING: Figure 6 【課題】流体機械の電気モータの駆動によるインバータ装置の温度の上がり易さについて、適切に監視することが可能となる監視システムを提供する。【解決手段】スイッチング素子を用いて流体機械における電気モータの駆動電力の電力変換動作を行うインバータ装置に関して、監視動作を行う監視システムであって、前記監視動作は、前記電気モータの駆動による前記インバータ装置の温度の上がり易さとの相関性を有する特定情報を監視し、当該温度の上がり易さが所定の基準条件に達したか否かを判別する動作である監視システムとする。【選択図】図６
