Abstract

Lors du fonctionnement d'un évaporateur à un degré de surchauffe prédéterminé, la position des tubes de transfert thermique qui est obtenue à une température à laquelle ne se produit pas de givrage est déterminée en tant que position spécifique. En outre, dans l'évaporateur, le pas des ailettes et/ou le pas des tubes de transfert thermique sur le fluide frigorigène en aval de la position spécifique est plus dense que celui sur le fluide frigorigène en amont, de telle sorte que la somme de la capacité de refroidissement du fluide frigorigène en amont de la position spécifique et de celle du fluide frigorigène en aval de la position spécifique n'est pas réduite. En conséquence, au cours de l'opération de refroidissement, le givrage du fluide frigorigène en aval peut être supprimé et l'intervalle entre les opérations de dégivrage peut être ajusté de manière à être plus long. De plus, étant donné que le pas des ailettes et/ou le pas des tubes de transfert thermique sur le fluide frigorigène côté aval de la position spécifique est dense, une réduction de la capacité de refroidissement est supprimée. La construction minimise le givrage sur un refroidisseur pour prolonger l'intervalle entre les opérations de dégivrage.
