Abstract

A reverse compression cycle machine (M) comprises an evaporator (9), a compressor (1) and a condenser (3) arranged in series along a path of a working fluid in the machine (M), and further comprises aboundary layer turbine (7) placed between the condenser (3) and the evaporator (9), wherein said turbine (7) comprises: a set of power disks (30) mounted on a shaft (33) which rotates inside a volumeof a rotor casing (53), an inlet opening (70) for introducing a working fluid in a stator volume (51), a stator nozzle (52), which accelerates the flow in a direction that is tangential to the powerdisks (30), and a discharge (73) of a working fluid, wherein the rotor casing (53) comprises a drain (71, 72) of a liquid fraction of said working fluid from the peripheral part of the power disks inorder to avoid its concentration in the peripheral part of the volume of said rotor casing.

Description

technical field [0001] The present invention relates to the field of reverse cycle, and in particular relates to improving the performance of a refrigeration system or a compression heat pump utilizing a working fluid (working fluid, working fluid) to undergo evaporation and condensation phase transitions in a closed circuit. [0002] The invention relates in particular to an energy recovery device for the pressure difference between the condenser and the evaporator of the above-cited reverse cycle, this energy being normally dissipated in suitable piping with reduced channel cross section or in a throttle valve . [0003] In order to reduce the energy dissipation of compression refrigeration systems, the present invention finds preferred and advantageous but non-limiting application in the refrigeration industry, such as those industrial scale (greater than 100 kW power) or domestic scale (less than 10 kW power) refrigeration compression systems. Background technique [00...
