In one embodiment, a method and a system for determining the operating state of a dynamic compressor that is mechanically connected to an electrical machine and that is equipped with a rotor that exchanges energy with a known fluid by rotating at a speed and with a driving mechanical torque, and in particular for determining the operating point of the dynamic compressor and the distance of the operating point from a surge limit curve, which delimits a stable operation zone from an unstable operation zone of the dynamic compressor.
A reversible turbomachine includes a rotor housing containing one or more rotor members, the rotor having a plurality of mutually spaced discs, which rotate about a rotational axis and are coaxially disposed about a rotational shaft; a primary stage for the flow of a high energy fluid, communicating with the rotor housing via at least one stator channel; a secondary stage for the flow of a low energy fluid; and at least one rotary distribution chamber for distributing the fluid to or from the rotor, the rotary distribution chamber being arranged in the internal space of the rotor housing and interposed between the at least one stator channel and at least part of the discs, the rotating distribution chamber having at least one rotor opening for the passage of the fluid between the primary stage and the rotor.

A reverse compression cycle machine includes an evaporator, a compressor and a condenser arranged in series along a path of a working fluid in the machine, further including a boundary layer turbine placed between the condenser and the evaporator. The turbine includes a set of power disks mounted on a shaft which rotates inside a volume of a rotor casing, an inlet opening for introducing a working fluid in a stator volume, a stator nozzle, which accelerates the flow in a direction that is tangential to the power disks, and a discharge of a working fluid. The rotor casing includes a drain of a liquid fraction of the working fluid from the peripheral part of the power disks in order to avoid its concentration in the peripheral part of the volume of the rotor casing.
