  • the operating mode spring / autumn operation only starts when there is no energy available in the storage facilities and electricity is required.
  • the print media hybrid engine generates the required electrical energy via the coupled generator.
  • large amounts of waste heat accumulate, which are intercepted with cooling water and stored in the heat storage. If required, this waste heat is used as heating supply and service water.
  • the domestic energy supply system switches to summer operation and uses the heat energy of the heat storage as the drive source for the evaporation process (see summer operation).
  • the domestic energy supply system switches to compressed air operation and supplies the compressed-fluid hybrid motor with compressed drive air for power generation.
  • the compressed air reservoir fills up especially in sunshine and very cold days.
  • An average 4 person household needs about 3000 KWh of electricity per year.
  • the cost of this is currently about the same as the electricity procurement costs.
  • the costs for heat generation for heating / hot water are eliminated because the waste heat of the print media hybrid engine is used for this purpose. And about 80% of the energy used is.
  • That the excess electrical energy or compressed air energy is e.g. available for a car use; but not all year.

Abstract

L'invention concerne une installation domestique d'alimentation en énergie (1). L'énergie calorifique de la différence de température entre au moins une source de chaleur (2, 3, 4) et au moins un puits de chaleur (5, 6, 7) est transformée en travail par une machine thermique (8). La machine thermique présente un circuit de fluide avec au moins deux réservoirs (9, 10) qui sont respectivement reliés thermiquement à la source de chaleur ou au puits de chaleur en tant que condenseur à refroidir ou qu'évaporateur à réchauffer. On règle pour une température de travail de 30° à 280° C une différence de température de travail d'environ 10° à 200° entre les réservoirs. La machine thermique présente un moteur hybride (11) sous la forme d'une combinaison d'un moteur à fluide sous pression et d'un moteur à combustion, dans lequel d'une part une différence de pression du fluide sur la base de la différence de température de travail est utilisée pour l'entraînement, et d'autre part un combustible est brûlé et transformé en travail. L'invention concerne en outre un procédé de commande d'une telle installation.
