Title
(EN) CLOSED CYCLE THERMAL ENERGY STORAGE SYSTEM USING THERMOCHEMICAL MATERIAL
(FR) SYSTÈME DE STOCKAGE D'ÉNERGIE THERMIQUE À CYCLE FERMÉ UTILISANT UN MATÉRIAU THERMOCHIMIQUE
Abstract
(EN)
A closed-cycle thermal energy storage system includes a thermochemical reactor [400] containing a solid thermochemical material, a heat exchanger [402], a fan [406] for creating forced convection of an air/water mixture circulating around the closed cycle, an evaporator/condenser [408], and a pressure control system that includes a pressure sensor [422], a controller [424], and a pump [404]. The pressure control system actively controls the pressure of the air/water mixture to produce a desired temperature difference across the thermochemical reactor [400]. The adjustable pressure control system controls the pressure of the air/water mixture to a first pressure (e.g., between 10 mbar and 1 bar) during a hydration phase and a second pressure (e.g., between 1 bar and 10 bar) during a dehydration phase.

La présente invention concerne un système de stockage d'énergie thermique à cycle fermé qui comprend un réacteur thermochimique [400] contenant un matériau thermochimique solide, un échangeur de chaleur [402], un ventilateur [406] pour créer une convection forcée d'un mélange air/eau circulant autour du cycle fermé, un évaporateur/condenseur [408], et un système de commande de pression qui comprend un capteur de pression [422], un dispositif de commande [424] et une pompe [404]. Le système de commande de pression commande activement la pression du mélange air/eau pour produire une différence de température souhaitée à travers le réacteur thermochimique [400]. Le système de commande de pression réglable commande la pression du mélange air/eau à une première pression (par exemple, entre 10 mbar et 1 bar) pendant une phase d'hydratation et une seconde pression (par exemple, entre 1 bar et 10 bars) pendant une phase de déshydratation.
