  • Patent number: 10337746
    Abstract: A heat pump has an evaporator for evaporating water as a working liquid so as to produce a working vapor, the evaporation taking place at an evaporation pressure of less than 20 hPa. The working vapor is compressed to a working pressure of at least 25 hPa by a dynamic-type compressor so as to then be liquefied within a liquefier by direct contact with liquefier water. The heat pump is preferably an open system, wherein water present in the environment in the form of ground water, sea water, river water, lake water or brine is evaporated, and wherein water which has been liquefied again is fed to the evaporator, to the soil or to a water treatment plant.
