Zusammenfassung:To provide a compressor which can determine an amount of an oil for lubricating a bearing part without causing significant cost increase, and to provide a method for determining an amount of the oil for lubricating the bearing part of the compressor.SOLUTION: The invention relates to a compressor including: a refrigerant gas compression part having a fixed side element and a rotary side element; a bearing part which supports the rotary side element of the refrigerant gas compression part in such a manner that the rotary side element may rotate relative to the fixed side element of the refrigerant gas compression part; a tank in which an oil for lubricating the bearing part is stored; a housing which houses the refrigerant gas compression part, the bearing part, and the tank; an acceleration sensor disposed at the same height position as a part of a side wall forming the tank and on the outer surface of the housing; and a determination part which determines an amount of the oil in the tank on the basis of an output value of the acceleration sensor.SELECTED DRAWING: Figure 4 【課題】有意なコストアップをもたらすこと無く、軸受部の潤滑のためのオイルの量を判別できるコンプレッサを提供すること、及び、コンプレッサの軸受部の潤滑のためのオイルの量を判別する方法を提供すること。【解決手段】本発明は、固定側要素と回転側要素とを有する冷媒ガス圧縮部と、前記冷媒ガス圧縮部の前記固定側要素に対して前記冷媒ガス圧縮部の前記回転側要素を回転可能に支持する軸受部と、前記軸受部の潤滑のためのオイルを貯留するタンクと、前記冷媒ガス圧縮部、前記軸受部及び前記タンクを包含するハウジングと、前記ハウジングの外面上であって、前記タンクを構成する側壁の一部と同じ高さ位置に配置された加速度センサと、前記加速度センサの出力値に基づいて、前記タンク内の前記オイルの量を判別する判別部と、を備えたことを特徴とするコンプレッサである。【選択図】図4
