To provide a highly efficient refrigerating cycle in a refrigerating cycle provided with an expansion/compression system converting energy of an expansion process of a working fluid into mechanical energy to carry out operation of one part of a compression process.
In the fluid machine, an expander part, a sub compressor part are installed in a sealed container, and the refrigerating cycle is composed such that the fluid machine is installed in a suction side of a main compressor wherein a sealed container internal pressure is considered as a discharge pressure of the sub compressor part, and the sealed container internal pressure becomes a suction pressure. An oil introduction pipe is connected connecting the fluid machine with the sealed container of the main compressor.
