| 摘要 |
The present invention concerns a thermal apparatus (1) comprising at least one primary circuit (P1) in which a heat transfer fluid referred to as the primary fluid is displaced by a drive device with an alternating motion, and at least one heat exchanging interface (I1.1, I1.2) between the primary fluid and a secondary fluid flowing unidirectionally in a secondary circuit (S1.1, S1.2), said apparatus being characterised in that said interface (l1.1, I1.2) comprises at least one heat exchange area (ZN, ZN+1, Z'N, Z'N+1) in which the primary fluid and the secondary fluid move unidirectionally and countercurrent relative to each other. |
