Claim:
1. A device for the exchange of thermal energy between a first medium flow from an outside area to an inside area to be conditioned and a second medium flow from inside the area to be conditioned to outside the area, comprising: a. a heat exchanger placed between an outside area and an inside area; b. a first supply duct for the conduction of the first medium flow connecting the outside area to the heat exchanger; c. a first exhaust duct for the conduction of the first medium flow connecting the inside area to the heat exchanger; d. a second supply duct for the conduction of the second medium flow connecting the inside area to the heat exchanger, of which the direction of flow is opposite to that of the first medium flow; e. a second exhaust duct for the conduction of the second medium flow connecting the outside to the heat exchanger; f. a first heat exchanger element placed in either the first supply duct or the second exhaust duct; and g. a second heat exchanger element placed in either the second supply duct or the first exhaust duct, wherein the first and second heat exchanger elements are both included in a Carnot circuit comprising an expansion device and a compressor so as to transfer heat between the first and second heat exchanger elements, wherein the heat exchanger is adapted for the exchange of both thermal energy and phase transition energy, wherein the connections of the compressor and the expansion device in the Carnot circuit are exchangeable with respect to the heat exchanger elements, and wherein the Carnot circuit is adapted for the transfer of thermal energy in the same direction as the energy transfer of the first medium flow.
