Device and method for converting heat energy

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.

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 ...
