Abstract: An evaporator or a condenser includes a surface on which the operating liquid is arranged. Further, turbulence generators are provided to generate turbulences in the operating liquid located on the operating surface. In the condenser, alternatively or additionally, a laminarizer is present to make the vapor stream laminar provided by the compressor. On the evaporator side, the evaporation efficiency is increased and, on the condenser side, the condenser efficiency is increased, which may be used for a substantial reduction in size without loss of power of these components, in particular for a heat pump for heating a building.

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.
