Abstract: A device and a method for converting low temperature thermal energy into high temperature thermal energy using mechanical energy with a rotor for a working medium passing through a closed cycle. The rotor has a compressor unit with compression channels and an expansion unit with expansion channels, and has heat exchangers for exchanging heat between the working medium and a heat exchange medium. The device has an impeller which can be rotated relative to the rotor. The impeller is arranged between supply channels which conduct the flow of the working medium in the heat pump and at least one rotor discharge channel which discharges the flow of the working medium in the heat pump. The supply channels have outlet sections which extend up to a point directly upstream of an inlet opening of the impeller such that flows of the working medium are conducted out of the supply channels.

Abstract: The invention relates to a device for converting thermal energy of a low temperature into thermal energy of a high temperature by means of mechanical energy, and vice versa, comprising a rotor which is mounted so as to rotate about a rotational axis and in which a flow channel is provided for a working medium that circulates in a closed circuit process, said medium being conducted outwards, relative to the rotational axis, in a compression unit in order to increase pressure, and being conducted inwards, relative to the rotational axis, in an expansion unit in order to reduce pressure. At least one heat exchanger is provided for exchanging heat between said working medium and a heat exchange medium.
