Title
(EN) FALLING LIQUID FILM TYPE TUBE ICE MACHINE
(FR) MACHINE À GLACE À TUBE DE TYPE À FILM LIQUIDE TOMBANT
(JA) 流下液膜式チューブアイス製氷機
Abstract
(EN)
A falling liquid film type tube ice machine according to one embodiment comprises: a casing; a plurality of heat transfer tubes that extend along the vertical direction inside the casing; and a header for storing a refrigerant, the header being provided in the region of the inner space of the casing where the upper ends of the heat transfer tubes are arranged. The heat transfer tubes are each configured so as to be supplied with the refrigerant from the header so that a liquid film of the refrigerant is formed on the outer surface of the heat transfer tube.

La présente invention concerne une machine à glace à tube de type à film liquide tombant selon un mode de réalisation qui comprend : un boîtier ; une pluralité de tubes de transfert de chaleur qui s'étendent le long de la direction verticale à l'intérieur du boîtier ; et un collecteur destiné à stocker un fluide frigorigène, le collecteur étant disposé dans la région de l'espace interne du boîtier où les extrémités supérieures des tubes de transfert de chaleur sont agencées. Les tubes de transfert de chaleur sont chacun conçus de façon à être alimentés en fluide frigorigène à partir du collecteur de telle sorte qu'un film liquide du fluide frigorigène est formé sur la surface externe du tube de transfert de chaleur.
