Patent number: 10995665Abstract: A compressed air energy storage power generation device includes an inert gas source for supplying an inert gas, an inert gas flow path system, and a flow path switching unit. The inert gas flow path system fluidly connects the gas phase portion of the high temperature heat storage unit, the gas phase portion of the low temperature heat storage unit, and the inert gas source. The flow path switching unit switches the inert gas flow path system to at least a state in which the inert gas source is in communication with both the high temperature heat storage unit and the low temperature heat storage unit and a state in which the inert gas source is blocked from both the high temperature heat storage unit and the low temperature heat storage unit.Type: GrantFiled: April 6, 2018Date of Patent: May 4, 2021Assignee: KOBE STEEL, LTD.Inventors: Masatake Toshima, Haruyuki Matsuda, Yohei Kubo

Patent number: 10234183Abstract: A compressing device of the present invention comprises a compressor, a heat exchanger, an expander, a power recovery unit, a condenser, a pump, a bypass flow passage for bypassing the expander, and a bypass valve. When a bypass condition for allowing a working medium to circulate through the bypass flow passage is satisfied, the bypass valve is caused to be opened, thereby allowing the working medium to circulate between the heat exchanger and the condenser through the bypass flow passage. As a result, a compressed gas discharged from the compressor is cooled by the working medium in the heat exchanger. This configuration makes it possible to cool the compressed gas by the working medium in the heat exchanger regardless of operation conditions of the expander.Type: GrantFiled: July 8, 2015Date of Patent: March 19, 2019Assignee: Kobe Steel, Ltd.Inventors: Koichiro Hashimoto, Kazumasa Nishimura, Shigeto Adachi, Yutaka Narukawa, Haruyuki Matsuda, Tetsuya Kakiuchi, Noboru Tsuboi, Kazunori Fukuhara
