Abstract (en)
[origin: WO2009066044A2] The invention relates to a cryogenic refrigeration device intended to transfer heat from a cold source (15) to a hot source (1) via a working fluid flowing through a closed working circuit (200) including the following portions in series, namely: a portion for the substantially isothermal compression of the fluid, a portion for the substantially isobaric cooling of the fluid, a portion for the substantially isothermal expansion of the fluid, and a portion for the substantially isobaric heating of the fluid. The compression portion of the working circuit (200) includes at least two compressors (7, 5, 3) disposed in series and the expansion portion of the working circuit (200) includes at least one expansion turbine (9, 11, 13), said compressors (7, 5, 3) and expansion turbine(s) (9, 11, 13) being driven by at least one high-speed motor (70) including an output shaft. One end of the output shaft supports and rotates, by means of direct coupling, a first compressor (7, 5, 3), while the other end of the output shaft supports and rotates, by means of direct coupling, a second compressor (7, 5, 3) or an expansion turbine (9, 11, 13).
