To provide a gas compressor capable of estimating effects obtained by upgrading a gas compressor more accurately than before without decomposing the gas compressor, a monitoring device for a gas compressor, and a monitoring method for a gas compressor.SOLUTION: A gas compressor calculates an amount of cooling heat of an air cooler 5 based on a state amount of compressed air detected by a state amount detection unit; calculates an operating condition of the air cooler 5 when replacing a compression mechanism unit 3 from the amount of cooling heat; calculates an operating cost when replacing the compression mechanism unit 3 based on the operating condition; calculates a replacement cost and energy saving effect when replacing the compression mechanism unit 3 based on the operating cost; and displays the calculation results of the replacement cost and energy saving effect on a display device 19.SELECTED DRAWING: Figure 1 【課題】気体圧縮機を分解せずとも、気体圧縮機のアップグレードにより得られる効果を従来に比べて高い精度で見積もることが可能な気体圧縮機、気体圧縮機の監視装置、および気体圧縮機の監視方法を提供する。【解決手段】態量検出部で検出された圧縮空気の状態量に基づいて空気冷却器５の冷却熱量を演算し、冷却熱量から圧縮機構部３を交換した場合における空気冷却器５の運転条件を演算し、運転条件に基づいて圧縮機構部３を交換した場合の運転費用を演算し、運転費用に基づいて圧縮機構部３を交換した場合の交換費用および省エネ効果を演算し、交換費用および省エネ効果の演算結果を表示装置１９に表示させる。【選択図】 図１
