Abstract
In order to provide a heat pumping method, in particular for generating cryogenic temperatures, which is efficient and less susceptible to malfunctions than known methods, the following, cyclically recurring method steps are suggested: Heating an electrically polarizable medium; cooling the heated polarizable medium by an operating medium; heating the operating medium in a regenerator; transferring part of the heat of the operating medium absorbed from the polarized medium to a warm-side heat exchanger; adiabatically terminating the action of the electric field on the polarized medium; cooling the stored operating medium; further cooling the operating medium cooled by the regenerator; cooling a cold-side heat exchanger with the operating medium cooled by the polarizable medium.
