Abstract
A heat pump in which an increased temperature rise is achieved, including heat accumulators behind one another in a cascade; caloric accumulator elements positioned alternatingly in thermally conducting contact with one of the heat accumulators; and at least one drive method or mechanism for changing the position of the accumulator elements between the heat accumulators, at least one of the heat accumulators is in contact with a component to control the temperature of this component, a last one of the heat accumulators in the cascade is in heat exchange with surroundings. An intermediate accumulator is formed from at least one of the heat accumulators for transmitting heat between a heat accumulator in contact with a component to be temperature-controlled and the last heat accumulator.
