Abstract:
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.
