Abstract

La présente invention concerne un système d'élévation de la température de l'eau à des niveaux souhaités et un système de production d'énergie électrique simultanément par le biais d'une cogénération utilisant une diode électroluminescente (DEL). Dans ce mode de réalisation de l'invention revendiquée, le système de chauffage de l'eau et de production d'énergie par cogénération utilise la capacité de la DEL alimentée par énergie de façon adéquate à produire simultanément de la chaleur utile et de l'énergie électrique. La chaleur utile est récupérée à partir du dissipateur de chaleur de la DEL et l'énergie électrique est produite à partir de la lumière émise à l'aide de cellules photovoltaïques. Le chauffe-eau à cogénération à base de DEL produit une chaleur suffisante pour remplacer des chauffe-eau et chaudières classiques, et produit suffisamment d'énergie pour charger la batterie embarquée qui peut alimenter des équipements collectifs électriques. Afin de rendre l'invention conviviale, des commandes sont prévues pour la régulation de la température, de la sécurité et du débit de l'eau. Les figures 1 à 5 illustrent l'invention.
