Publication number: 20160069600Abstract: 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: ApplicationFiled: July 8, 2015Publication date: March 10, 2016Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.)Inventors: Koichiro HASHIMOTO, Kazumasa NISHIMURA, Shigeto ADACHI, Yutaka NARUKAWA, Haruyuki MATSUDA, Tetsuya KAKIUCHI, Noboru TSUBOI, Kazunori FUKUHARA
