Abstract (en)
[origin: WO2018166740A1] The invention relates to a heat pump (12, 26) comprising at least one evaporator (10), a subsequent downstream compressor (7a, 7b, 7), a subsequent downstream liquefier (8), and at least one subsequent downstream expansion device (9a, 9b, 9) for expanding the fluid, characterised in that, along the fluid circuit, there are arranged at least two expansion devices (9a, 9b) in series between the liquefier (8) and evaporator (10) and at least two compressors (7a, 7b) in series between the evaporator and liquefier, wherein a separator (30) for separating a gas phase and liquid phase is arranged between the two expansion devices for introducing steam between the compressors, and there are arranged means (34) for superheating the fluid (2) flowing from the evaporator.
