Title (EN) USE OF EXTERNAL AIR FOR CLOSED CYCLE INVENTORY CONTROL
(FR) UTILISATION D'AIR EXTERNE POUR UNE COMMANDE D'INVENTAIRE À CYCLE FERMÉ
Abstract:
(EN) Systems and methods relating to use of external air for inventory control of a closed thermodynamic cycle system or energy storage system, such as a reversible Brayton cycle system, are disclosed. A method may involve, in a closed cycle system operating in a power generation mode, circulating a working fluid may through a closed cycle fluid path. The closed cycle fluid path may include a high pressure leg and a low pressure leg. The method may further involve in response to a demand for increased power generation, compressing and dehumidifying environmental air. And the method may involve injecting the compressed and dehumidified environmental air into the low pressure leg.
(FR) L'invention concerne des systèmes et des procédés se rapportant à l'utilisation d'air externe pour la commande d'inventaire d'un système à cycle thermodynamique fermé ou d'un système de stockage d'énergie, tel qu'un système à cycle Brayton réversible. Un procédé peut consister à faire circuler un fluide de travail à travers un trajet de fluide à cycle fermé dans un système à cycle fermé fonctionnant dans un mode de production d'énergie. Le trajet de fluide à cycle fermé peut comprendre une jambe haute pression et une jambe basse pression. Le procédé peut en outre consister en réponse à une demande pour une production d'énergie accrue, une compression et une déshumidification de l'air ambiant. Le procédé peut aussi impliquer l'injection de l'air ambiant comprimé et déshumidifié dans la jambe basse pression.
