Title: COMPRESSED AIR STORAGE POWER GENERATION DEVICE
Abstract:
A compressed air storage power generation device 2 is provided with a third heat exchanger 30 and fourth heat exchangers 40a, 40b. The third heat exchanger 30 exchanges heat between air exhausted from an expander 24 and a second heat medium to cool the second heat medium. The fourth heat exchanger 40a or 40b exchanges heat between the second heat medium cooled by the third heat exchanger 30 and a lubricating oil to be supplied to a compressor 18 and/or a first heat medium to be supplied to a first heat exchanger 26, to cool the lubricating oil or the first heat medium. This makes it possible in the compressed air storage power generation device 2 to collect and utilize the cold energy exhausted from the expander 24 as a cold energy source, and to increase the energy efficiency of the system without requiring an external supply of cold energy, i.e., without limiting the freedom of installation location.
