1. A heat pump system comprising:
- a heat pump stage comprising a first evaporator, a first liquefier, and a first compressor; and
a further heat pump stage comprising a second evaporator, a second liquefier, and a second compressor,wherein a first liquefier exit of the first liquefier is connected to an evaporator entrance of the second evaporator via a connecting lead, so that during operation of the heat pump system, working liquid from the first liquefier of the heat pump stage enters into the second evaporator of the further heat pump stage via the connecting lead and evaporates within the second evaporator of the further heat pump stage to obtain evaporated working liquid in the second evaporator,wherein the heat pump stage and the further heat pump stage are connected to operate in a cascade connection, andwherein the heat pump stage and the further heat pump stage are connected so that the evaporated working liquid in the second evaporator is compressed by the second compressor of the further heat pump stage.
