Abstract (en)
[origin: WO2021023458A1] Disclosed is a low-temperature refrigeration device comprising a working circuit (10) that forms a loop and contains a working fluid, the device (1) further comprising a cooling exchanger (8) for extracting heat from at least one member (25) by exchanging heat with the working fluid, the working circuit (10) forming a cycle comprising, connected in series: a compression mechanism (2, 3), a cooling mechanism (6), an expansion mechanism (7) and a heating mechanism (6, 8), wherein the mechanism for cooling the working fluid and the heating mechanism comprise a common heat exchanger (6) in which the working fluid flows in opposite directions in two separate transit portions of the circuit according to whether it is cooled or heated, the device (1) being designed to ensure equal mass flow rates in the two transit portions in the common heat exchanger (6), the device (1) also comprising a bypass (9) for bypassing one of the two transit portions, said bypass (9) comprising a bypass valve (11) which, in the open state, changes the mass flow rate in one of the two transit portions.
