Abstract

Production de chaleur avec récupération d’électricité. Ce système pourra être utilisé pour le chauffage ou la production d’eau chaudeHeat production with electricity recovery. This system can be used for heating or hot water production

Description

Chauffage avec récupération d’énergie.Heating with energy recovery.

Une résistance électrique est capable de produire une température de plusieurs centaines de degrés, alors que pour le chauffage une température de quelques dizaines de degrés est suffisante. Le principe est de transformer une haute température en basse température en récupérant l’énergie par une variation d’entropie. Dans un réchauffeur électrique, on vaporise un gaz qui sera dirigé vers une turbine. L’échappement de cette turbine sera relié à un condenseur atmosphérique. Le gaz une fois condensé, et devenu liquide sera envoyé vers une pompe volumétrique capable de refouler à haute pression puis sera dirigé à nouveau vers le réchauffeur électrique. La turbine entrainera sur son axe la pompe volumétrique et un moteur asynchrone. Au démarrage le moteur asynchrone entrainera l’ensemble pompe et turbine, le réchauffeur électrique étant lui même alimenté. La température augmentant dans le réchauffeur le gaz sera vaporisé et envoyé vers la turbine qui sera entrainée, ensuite le gaz sera condensé puis sous forme liquide pompé pour revenir à la haute pression et renvoyé vers le réchauffeur. Le moteur asynchrone étant entrainé par la turbine il consommera de moins en moins d’électricité puis en produira lorsqu’il aura dépassé sa vitesse de synchronisation, cette électricité viendra en déduction de l’électricité consommée. La quantité de chaleur utilisable sera la même mais plus basse et la consommation réduite.An electrical resistance is capable of producing a temperature of several hundred degrees, while for heating a temperature of a few tens of degrees is sufficient. The principle is to transform a high temperature into a low temperature by recovering energy through a variation of entropy. In an electric heater, a gas is vaporized which will be directed towards a turbine. The exhaust of this turbine will be connected to an atmospheric condenser. The gas once condensed, and become liquid, will be sent to a positive displacement pump capable of delivering at high pressure and then will be directed again to the electric heater. The turbine will drive the positive displacement pump and an asynchronous motor on its axis. On start-up, the asynchronous motor will drive the pump and turbine assembly, the electric heater itself being powered. As the temperature increases in the heater, the gas will be vaporized and sent to the turbine which will be driven, then the gas will be condensed then in liquid form pumped back to high pressure and returned to the heater. As the asynchronous motor is driven by the turbine, it will consume less and less electricity and then produce it when it has exceeded its synchronization speed, this electricity will be deducted from the electricity consumed. The amount of usable heat will be the same but lower and consumption reduced.
