Device and method for converting heat energy

Abstract

The invention relates to a device (20) and a method for converting lower-temperature thermal energy into higher-temperature thermal energy using mechanical energy and performing the process in reverse, having a rotor (21) for a working medium that undergoes a closed circulation process. and an impeller (30) rotatable relative to the rotor (21), wherein the rotor (21) has a compression unit (23) equipped with a plurality of compression passages (25) and a decompression unit (26) equipped with a plurality of decompression passages (26). 24), wherein the rotor (21) additionally has a heat exchanger (1', 1") for heat exchange between the working medium and the heat exchange medium, wherein the impeller (30) is arranged on the rotor (21 ) between an input channel (31) that supplies a working medium flow in the heat pump operating state and at least one outlet channel (32) that discharges a working medium flow in the heat pump operating state, wherein the input channel (31) has a substantially parallel The outlet section (34) of the axis of rotation (22) extends up to the inlet (33) of the impeller (30), so that the individual flows of the working medium can emerge from the inlet channel (31) essentially parallel to the axis of rotation (22) into the impeller (30).

Description

technical field [0001] The present invention relates to a device for converting lower temperature thermal energy into higher temperature thermal energy and converting higher temperature thermal energy into lower temperature thermal energy by utilizing mechanical energy, which has a device for passing through A rotor of the working medium in a closed cycle process and an impeller rotatable relative to the rotor, wherein the rotor has a compression unit with a plurality of compression channels and a pressure reduction unit with a plurality of pressure reduction channels, the flow of the working medium can be increased in order to increase the pressure Leading substantially radially outwards with respect to the axis of rotation into the compression channel, the flow of the working medium can be directed essentially radially inwards with reference to the axis of rotation into the pressure relief channel for reducing the pressure, wherein the rotor also has an A heat exchanger for ...
