Abstract
A hybrid heat pump wherein the operating medium is a mixture of media which dissolve in each other and have different boiling points. The condensation and/or the evaporation is performed on more than one pressure levels and at variable temperatures. The compressor performs the suction on more than one pressure levels and performs the discharge on more than one pressure level. Between low pressure operating medium (p.sub.1, p.sub.2) and large pressure operating medium (p.sub.3, p.sub.4, p.sub.5) the heat transfer is performed by the internal heat exchangers.
