Beschreibung
Zusammenfassung:	A compressed air energy storage and power generation device 2 comprises a motor 46, a compressor 8, a pressure accumulation tank 10, an expander 12, and a generator 44. The motor 46 is driven by a fluctuating input power. The compressor 8 is mechanically connected to the motor 46 and compresses air. The pressure accumulation tank 10 is fluidly connected to the compressor 8 and stores air compressed by the compressor 8. The expander 12 is fluidly connected to the pressure accumulation tank 10 and is driven by compressed air supplied from the pressure accumulation tank 10. The generator 44 is mechanically connected to the expander 12 and generates power to be supplied to a user 6. A cooling water flow path, whereby water flows inside a cooling water pipe 42 for cooling air that is a working fluid, is provided inside a casing 8c of the compressor 8. As a result, a compressed air energy storage and power generation device 2 can be provided that is capable of efficiently reducing compressive axial force and of reducing power consumption.
