Abstract
A compressed fluid storage power generation device including a compressor and compressor bodies for compressing a working fluid; a pressure accumulation tank for storing the working fluid compressed by the compressor bodies; a power generator having expanders which are driven by the working fluid and a power generator body which is driven by the expanders; high-temperature heat recovery units for recovering heat from the working fluid flowing from the compressor bodies into the pressure accumulation tank; high-temperature heating units for heating, with the recovered heat, the working fluid flowing from the pressure accumulation tank into the expanders; a low-temperature heat recovery unit for recovering heat generated in a low-temperature heat generation section of the compressor and/or power generator into a low-temperature heat carrier; and low-temperature heating units for heating the working fluid by means of heat exchange with the low-temperature heat carrier carrying the heat recovered by the low-temperature heat recovery unit.
