FLUID MACHINE, AND RANKINE CYCLE

摘要

A fluid machine is provided with: a first shaft; a compressor-expander fluid machine; a planetary gear mechanism configured from a sun gear connected to a second shaft which rotates in synchronization with the compressor-expander fluid machine, a ring gear connected to the first shaft, a planetary gear, and a planetary carrier; a first clutch which fastens/releases the planetary gear with/from the ring gear or the sun gear; a second clutch which fastens/releases the planetary carrier with/from a housing; and a clutch control means for controlling the fastening/releasing operation of the first clutch and the second clutch depending on whether the compressor-expander fluid machine is actuated as an expander or as a compressor.
