Title
(EN) CRYOGENIC FLUID MANAGEMENT
(FR) GESTION DE FLUIDE CRYOGÉNIQUE
Abstract
(EN)
According to an example aspect of the present invention, there is provided a system comprising a cryogenic liquid storage tank, a first pressure tank and a second pressure tank, both connected via leads to the storage tank, at least one ejector, each of the at least one ejector being connected via leads to both pressure tanks, and a controller, the controller being configured to admit cryogenic fluid from the storage tank to the first pressure tank, to cause the cryogenic fluid to be heated to convert it into gas form, and to admit the fluid in gas form from the first pressure tank through a first ejector from among the at least one ejector, such that the fluid in gas form acts as a motive fluid to cause evacuation of the second pressure tank as it passes through the first ejector.
(FR)
Selon un aspect donné à titre d'exemple de la présente invention, l'invention concerne un système comprenant un réservoir de stockage de liquide cryogénique, un premier réservoir sous pression et un second réservoir sous pression, tous deux raccordés par l'intermédiaire de fils au réservoir de stockage, au moins un éjecteur, chacun du ou des éjecteurs étant raccordé par l'intermédiaire de fils aux deux réservoirs sous pression, et un dispositif de commande, le dispositif de commande étant conçu pour admettre un fluide cryogénique du réservoir de stockage au premier réservoir sous pression, afin d'amener le fluide cryogénique à être chauffé de manière à le convertir sous forme gazeuse, et afin d'admettre le fluide sous forme gazeuse à partir du premier réservoir sous pression à travers un premier éjecteur parmi le ou les éjecteurs, de sorte que le fluide sous forme gazeuse agit comme un fluide moteur afin de provoquer l'évacuation du second réservoir sous pression lorsqu'il passe à travers le premier éjecteur.
