Definitions

  • the invention relates to a device for compressing a gas by means of solar energy and / or ambient heat.

  • Heat exchanger is exposed to solar radiation and / or the two heat exchangers are at different temperature levels, so that a compressor is provided which can be driven by a pneumatic cylinder, which uses the pressure difference between the two secondary sides, so that the compressor conveys gas into a store and that a pump is provided to pump the gas from the secondary side of the first heat exchanger into the secondary side of the second heat exchanger and vice versa after the pressure equalization.
  • the pressure difference between the two high pressure heat exchangers is converted into mechanical energy in the compressor. When the pressure is equalized, there is still a high gas pressure inside the two high-pressure heat exchangers compared to the atmospheric pressure in the environment.
  • the primary side of the second heat exchanger is additionally the gas which comes from the store after it has been expanded in a utility turbine. In this way, the expansion energy of the gas is used for the cooling of the second heat exchanger during the expansion.
  • the primary side of the first heat exchanger is the gas which is conveyed into the store by the compressor.
  • the compression heat generated in the compressor during gas compression is also fed to the first high-pressure heat exchanger. After the compressed gas flows through the primary side of the first high-pressure heat exchanger, the compressed gas is fed to the pressure reservoir.
  • At least one further compressor is provided for conveying further gas into the pressure accumulator, preferably via the primary side of the first heat exchanger or a further heat exchanger, which is generated by other energy, such as braking energy, wind energy or electrical energy obtained from photocells , drivable is. In this way it is possible to feed the braking energy back into the pressure accumulator through energy conversion.

Abstract

La présente invention concerne un dispositif servant à comprimer un gaz grâce à l'énergie solaire ou à la chaleur ambiante, ledit dispositif comprenant deux échangeurs thermiques haute pression (1, 2). Un échangeur thermique haute pression (1) sert de collecteur solaire et l'autre échangeur thermique haute pression (2) sert de dispositif de refroidissement. Les deux échangeurs thermiques haute pression (1, 2) sont reliés par des conduites tubulaires, des soupapes (8, 31, 32, 33) et un cylindre pneumatique (5). En raison des différents niveaux de température des deux échangeurs thermiques haute pression (1, 2) se forme une différence de pression qui déplace le cylindre pneumatique (5). Le cylindre pneumatique (5) agit sur un compresseur (40). Afin d'utiliser la chaleur de compression, la gaz comprimé est introduit dans la partie primaire de l'échangeur thermique haute pression (1) agissant en tant que collecteur. L'air pressurisé emmagasiné est utilisé pour entraîner une turbine (12). Le gaz détendu par une turbine (12) diminue fortement de température et est introduit dans la partie primaire de l'échangeur thermique haute pression (2) agissant en tant que dispositif de refroidissement. Un système d'échangeurs thermiques haute pression de ce type peut être utilisé pour entraîner des automobiles ou en tant qu'installation fixe, sur des toits de bâtiments par exemple.
