Title
(EN) SYSTEMS AND METHODS FOR ENERGY HARVESTING IN A CONTAINED FLUID CIRCUIT
(FR) SYSTÈMES ET PROCÉDÉS DE COLLECTE D'ÉNERGIE DANS UN CIRCUIT DE FLUIDE FERMÉ
Abstract
(EN) Systems and methods for harvesting energy from a closed fluid circuit, such as a water pipe system in a building. An energy harvester can be installed at a point in a water circuit and can generate energy from pressure differentials caused when a valve is opened or closed at any other point in the water circuit that is in fluid communication with the energy harvester. The energy can be used to power, for example, a sensor and/or a transmitter.
(FR) L'invention concerne des systèmes et des procédés de collecte de l'énergie qui provient d'un circuit de fluide fermé, comme un système de conduites d'eau dans un immeuble. Un collecteur d'énergie peut être installé à un certain point au sein d'un circuit d'eau et peut générer de l'énergie à partir des différentiels de pression provoqués lorsqu'une soupape est ouverte ou fermée à n'importe quel autre point au sein du circuit d'eau qui est en communication fluidique avec le collecteur d'énergie. L'énergie peut être utilisée pour alimenter, par exemple, un capteur et/ou un émetteur.
