Device for transferring heat from a gaseous working medium

A device (1) for transferring heat from a gaseous working medium (M2) to a heat-exchanger medium (M3) by compressing the gaseous working medium (M2), wherein the device (1) comprises:

• an operating line (AL), wherein the volume (V) enclosed by the operating line (AL) is divided into at least two sections, namely a first (AL-V1) and a second section (AL-V2), wherein the first section (AL-V1) is set up to hold a pressure-transfer medium (M1) and the second section (AL-V2) is set up to hold and discharge the gaseous working medium (M2), wherein at least one inlet and outlet valve (2) is provided to hold and discharge the gaseous working medium (M2), wherein a first volume delimited by the first section (AL-V1) is separated from a second volume delimited by the second section (AL-V2) by a first separating layer (T12) that can be displaced within the operating line (AL), wherein the first separating layer (T12) is arranged in such a way that pressure differences between the first (AL-V1) and second (AL-V2) sections of the operating line (AL) are equalized by a displacement of the first separating layer (T12) in the operating line (AL) and an accompanying change in the proportion between the first volume and the second volume is equalized;
• and
• a heat-exchanger line (WL) to hold the heat-exchanger medium (M3),
• wherein the heat-exchanger line (WL) is coupled to the first section (AL-V1) of the operating line (AL) in order to bring about pressure equalization by connecting the heat-exchanger line (WL) to the first section (AL-V1) of the operating line (AL) and a second separating layer (T13) is provided between these lines (WL, AL) for separating the lines (WL, AL) from each other, wherein the second separating layer (T13) is designed and arranged in such a way that there is a continuous pressure equalization between the heat-exchanger line (WL) and the first section (AL-V1) of the operating line (AL), and
• wherein the second section (AL-V2) of the operating line (AL) comprises a heat-emission section (AL-VT) enclosed by a two-part heat-absorption section (WL′) of the heat-exchanger line (WL) on the outside and inside while the operating line (AL) comprises an inner wall (AL-IW) and an outer wall (AL-AW) encapsulating the inner wall (AL-IW), and, between the inner wall (AL-IW) and the outer wall (AL-AW), a working-medium gap (S-M2) is formed to guide the working medium (M2), wherein the inner wall (AL-IW) is enclosed by a channel (K) through which a first part of the heat-exchanger line (WL) is formed in the heat-absorption section (WL′), and the heat-exchanger line (WL) in the heat-absorption section (WL′) also comprises a shell wall (WL-M) enveloping the outer wall (AL-AW) of the operating line (AL), through which a second part of the heat-exchanger line (WL) is formed and delimited in the heat-absorption section (WL′), wherein, between the outer wall (AL-AW) of the operating line (AL) and the shell wall (WL-M) of the heat-exchanger line, (WL), a heat-exchanger-medium gap (S-M3) connected in parallel with the channel (K) is formed so that a heat-exchanger medium (M3) conveyed in the heat-absorption section (WL′) of the heat-exchanger line (WL) can flow around the operating line (AL) on the outside via the heat-exchanger-medium gap (S-M3) and on the inside via the channel (K).
