Definitions

  • the invention relates to a method and a device for generating power (shaft work and cooling capacity) by utilizing a temperature difference between the cooling capacity of cryogenic liquid nitrogen (or liquid air) and the low-temperature heat in nature.
  • the liquid nitrogen (or liquid air) leaving the liquid turboexpander has a temperature of 77K and a pressure of 0.1-0.12MPa. It enters the liquid storage tank for 1 cycle use.
  • the flash gas that enters the liquid t tank at the same time as the liquid nitrogen (or liquid air) passes through the refrigeration system 1 1, 1 2, 1 3, 1 4 to be liquefied and returns to the liquid storage tank.

Abstract

L'invention se rapporte à un procédé et appareil permettant de produire de l'énergie (puissance d'arbre et énergie de refroidissement) à partir d'une source à basse température. L'appareil est conçu comme un système qui comprend un dispositif de chauffage (3), des turbines (4, 5, 9), un condenseur-évaporateur (2), un échangeur thermique (22), un condenseur (8), une cuve pour le stockage du liquide (1), une pompe haute pression (6), des pompes centrifuges (7, 10). Le système est structuré comme un circuit continu avec un réseau de canalisations de refroidissement à températures cryogéniques et un système de refroidissement à vaporisation éclair, dans lequel circule un fluide thermodynamique de refroidissement à températures cryogéniques. On chauffe le fluide thermodynamique dans le dispositif de chauffage (3) en utilisant l'énergie basse température de l'air de l'atmosphère, puis on refroidit cet air. On détend le fluide thermodynamique dans les turbines (4, 5, 9) pour produire de la puissance d'arbre. On détend puis on liquéfie le fluide thermodynamique à l'état de vapeur pour en faire du fluide thermodynamique de refroidissement à températures cryogéniques qui va être utilisé à des fins de recyclage.
