A thermodynamic device includes a first liquid container configured to maintain a first pressure during operation, the first liquid container being partially filled with a working fluid during operation, a second liquid container configured to maintain a second pressure during operation, the second pressure being higher than the first pressure, the second liquid container being partially filled with the working fluid during operation; and a compensation pipe permeable to the working fluid and including an inlet arranged within the second liquid container so as to define, during operation, a working fluid level within the second liquid container, and including an outlet arranged within the first liquid container so that working fluid can be transported from the inlet into the outlet, the inlet being arranged to be higher up than the outlet in the installation direction.
