<p>The hollow bodies (1) of the heat pump include first zones (4) and second zones (5), between which the working fluid is reversibly displaced. Equilibrium between zones is a function of thermodynamic state variables. In novel design, the hollow bodies each have a first active area (6) and first zone (4), lying opposite a second active area (7) and second zone (5). These (6, 7) are each planar and rectangular. There is a rectangular hollow space (10) between the active areas.</p> |
