Abstract

L'invention concerne un système de micro-cogénération qui permet d'utiliser la chaleur récupérée d'un cogénérateur à la fois pour chauffer un espace et pour générer de l'eau chaude par raccordement du cogénérateur à un canal de fluide caloporteur de la chaudière. Ce système simplifié permet ainsi de réduire les coûts d'installation et de commander plus facilement la chaleur à fournir en mode chauffage et en mode eau chaude. Le système de micro-cogénération selon l'invention comprend un cogénérateur (100) comportant un échangeur de chaleur (110) pour récupérer la chaleur résiduelle qui est produite pendant la génération de puissance, une chaudière (200) servant à faire circuler sélectivement un fluide caloporteur ayant absorbé de la chaleur provenant de l'échangeur de chaleur (110) jusqu'à un endroit à chauffer ou à un échangeur de chaleur pour eau chaude (230), l'échange de chaleur avec l'eau provenant directement du réseau servant à fournir de l'eau chaude, et un réservoir (300) utilisé pour stocker le fluide caloporteur qui est raccordé de sorte que le fluide caloporteur stocké est acheminé vers l'échangeur de chaleur (110) du cogénérateur (100).
