Title (EN) METHOD FOR CONVERSION OF LOW TEMPERATURE HEAT TO ELECTRICITY AND COOLING, AND SYSTEM THEREFORE
(FR) PROCÉDÉ PERMETTANT DE CONVERTIR UNE CHALEUR À BASSE TEMPÉRATURE EN ÉLECTRICITÉ ET REFROIDISSEMENT ET SON SYSTÈME
Abstract:
(EN) A method for producing electrical energy is disclosed which uses a heat source, such as solar heat, geothermal heat, industrial waste heat or heat from power production processes, providing heat of 150 °C or below, further comprising an absorber system in which a working gas, primarily carbon dioxide CO2, is absorbed into an absorbent, typically an amine, further comprising a reactor which receives heat from said heat source and in which the absorbent-CO2 mixture is split into CO2 and absorbent, further comprising an expansion machine, an electricity generator and auxiliary equipment such as pumps, pipes and heat exchangers. The system according to the method allows the cost-efficient production of electrical energy and cooling using low value heat source.
(FR) La présente invention a trait à un procédé permettant de produire de l'énergie électrique, lequel procédé utilise une source de chaleur, telle que la chaleur solaire, la chaleur géothermique, la chaleur perdue industrielle ou la chaleur provenant de processus de production d'énergie, qui fournit une chaleur inférieure ou égale à 150 °C. Ledit procédé comprend en outre un système absorbeur où un gaz de travail, principalement du dioxyde de carbone CO2, est absorbé dans un absorbant, en règle générale une amine, un réacteur qui reçoit la chaleur provenant de ladite source de chaleur et où le mélange absorbant-CO2 est séparé en CO2 et en absorbant, une machine de dilatation, un générateur électrique et un équipement auxiliaire tel que des pompes, des tuyaux et des échangeurs de chaleur. Le système selon le procédé permet d'obtenir une production rentable d'énergie électrique et un refroidissement à l'aide d'une source de chaleur de faible valeur.
