Heat pump

A method for operating a heat pump comprising an evaporator for evaporating a fluid in order to obtain an evaporated fluid, wherein the evaporator comprises an evaporator sump;

• a condenser for condensing a compressed fluid, wherein the condenser comprises a condenser sump;
• a compressor having a first compressor stage and a second compressor stage, wherein the compressor is arranged in the flow direction of the evaporated fluid, during operation of the heat pump, between the evaporator and the condenser, and is configured to compress the evaporated fluid in order to obtain the compressed fluid;
• wherein the method comprising the steps of:
• collecting an intermediate cooling fluid in a container;
• and
• causing the intermediate cooling fluid to flow from the container through a heat exchanger with a pipeline, wherein the pipeline is arranged in a flow region between the first compressor stage and the second compressor stage, in order to cool vaporous fluid in the flow region.
