Abstract

On utilise un récupérateur de chaleur (1) dans une machine frigorifique du type à compression, dans laquelle une pression d'un fluide frigorigène à une partie à haute pression atteint et dépasse une pression critique. Un fluide frigorigène à basse pression s'écoule à travers le récupérateur de chaleur. Le récupérateur de chaleur comprend un tube plat (2, 6) ; des canaux de fluide frigorigène (2a, 6a, 6b) compris dans le tube ; et des colonnes intérieures (2b) disposées entre les canaux de fluide frigorigène. On définit une résistance à la traction du matériau du tube, en tant que S [N/mm2] ; pour l'un des canaux de fluide frigorigène, une dimension sensiblement parallèle à un sens de grand axe du tube, en tant que Wp [mm] ; et pour l'une des colonnes, une épaisseur sensiblement parallèle au sens de grand axe du tube, en tant que Ti [mm]. Ici, [447 x Wp / {10^(1,54 x log10S)} - 533 / {10^(1,98 x log10S)}] ≤ Ti ≤ [447 x Wp / {10^(1,54 x log10S)} - 533 / {10^(1,98 x log10S)}] x 2,3.
