Definitions

  • the subject of the present invention is a device for recovering rainwater and solar energy originating from light radiation.
  • This collection device is intended for buildings and is able to be mounted at the base of a roof or on the edge of a balcony.
  • Solar energy can be recovered by using solar sensors generally positioned on the roof of the buildings. Inside these sensors a heat-transfer fluid is set in motion which can then be used to transmit the heat inside the rooms, for example by means of individual solar water heaters (ISWH) and/or floors fitted with passages for the heat-transfer fluid (sometimes called “direct solar floors” or COMBI).
  • ISWH individual solar water heaters
  • COMBI direct solar floors
  • Water- or heat-transfer fluid-based solar converters are known, generally made of metal or composite materials, comprising a bottom part consisting of a box, an insulator, an absorber and a collector and a top part consisting of a translucent or transparent panel thus providing a greenhouse effect. Also known are heat-transfer fluid-based solar converters made of metallic materials and of glass that can be used in vacuum operation.
  • these converter devices or solar sensors used in the buildings have a flat geometry (assemblies of vacuum modules or tubes for an area of 2 m ⁇ 1 m for example) and have only a single functionality, to collect the heat deriving from the solar radiation.
  • the object of the present invention is to increase the efficiency of solar energy collection compared to the devices normally used, thus to increase the heat efficiency of these solar devices, and to propose a solar product that is fully integrated into the building, and having at least a dual function of rainwater recovery and collection of the energy deriving from the solar radiation.
  • Another object of the present invention is to provide a device that is lightweight, easy to fit and that can generate heat and/or electricity.
  • the present invention provides for the use of physical effects linked to the conversion of the solar radiation such as absorption and the greenhouse effect by using for its structure a collection device mounted on the base of a roof of a building or on the edge of a building balcony.
  • Heat recovery is achieved through a heat exchanger using the greenhouse effect, and which is installed on a sanitary or heating hot water production device.
  • the collection device thus offers a dual function, being capable of both recovering the rainwater and recovering the solar energy to transmit it to a heat-transfer fluid which can be water or another fluid. Furthermore, depending on the coating of the heat-exchanger's absorber, it is also possible to generate electricity.
  • the device for collecting rainwater and energy originating from solar radiation that makes it possible to both drain the rainwater and generate sanitary or heating hot water, or even electricity, can be mounted at the base of a roof or on the edge of a balcony and comprises an open channel having longitudinal walls and side walls.
  • a translucent or transparent covering element is fitted inside the open channel, being maintained by the side walls and defining, inside the open channel, a watertight sealed chamber.
  • a heat-exchanger device inside which a heat-transfer fluid can circulate, is fitted inside said sealed chamber.
  • the translucent covering element defines, with at least a part of a longitudinal wall of the channel, a flow section for the rainwater.
  • the translucent or transparent covering element comprises a plate defining, with a part of the longitudinal walls, the watertight sealed chamber.
  • the bottom part of the channel defines the watertight sealed chamber.
  • the device also comprises at least one longitudinal bottom wall positioned in the open channel at a distance from a bottom wall of the channel, said longitudinal bottom wall forming the bottom of the watertight sealed chamber and partly delimiting the flow section for the rainwater.
  • the longitudinal bottom wall can be made of synthetic materials (polymer or composite type), glass, metal or alloy.
  • the longitudinal bottom wall extends from one of the internal longitudinal walls of the open channel to the vicinity of the opposite internal longitudinal wall so as to leave a space between said opposite internal wall and the longitudinal bottom wall.
  • the translucent covering element is of generally tubular form.
  • the device comprises an additional trough positioned inside the open channel and partly surrounding the translucent covering element, said trough being covered by a reflecting element so as to increase the solar concentration effect inside the translucent covering element.
  • the additional trough is preferably connected to one of the longitudinal walls of the open channel.
  • the absorber which can have different inclinations according to the latitude of the installation site and the geometry of the device, ensures an optimum solar radiation concentration effect with a high efficiency.
  • the open channel and the side walls can be made of synthetic materials (polymer or composite type), glass, metal or alloy.
  • the open channel over its part concerning the recovery of solar heat, has a translucent or transparent covering providing the greenhouse effect and can, in its bottom part, have an insulating plate.
  • the open channel over its part concerning the evacuation of the rainwater, can be coated on the inside, with a reflecting coating so as to increase the solar concentration effect.
  • the heat-exchanger device consists of a metal plate, preferably corrugated, which serves as an absorber, and at least one metal pipe for carrying the heat-transfer fluid.
  • the corrugated metal plate is coated on its top side with a selective black paint, a black coating produced by anodization, or a mono- or polycrystalline silicon type mineral coating, absorbing the heat optimally and radiating in the long wavelengths, so maximizing the greenhouse effect.
  • a selective black paint a black coating produced by anodization
  • a mono- or polycrystalline silicon type mineral coating absorbing the heat optimally and radiating in the long wavelengths, so maximizing the greenhouse effect.
  • the metal pipe or pipes can be welded to the bottom side of the corrugated metal plate and fixed to the side walls of the open channel.
  • the corrugated profile provides for a greater heat efficiency by concentration effect. There is advantageously a separation between the corrugated metal plate and the translucent or transparent covering, so favouring temperature rise inside the solar sensor part.
  • the metal plate is coated with at least one mineral to convert the radiation into electricity.
  • the mineral coating can, for example, be silicon.
  • the heat-exchanger device comprises at least one metal or composite synthetic material line welded fixed to the side walls and used to convey the heat-transfer liquid.
  • the metal line(s) is/are covered with a selective black paint, a black coating produced by anodization, or a mono- or polycrystalline silicon type mineral coating, the lines made of composite synthetic material incorporate black monochromatic polymers, so absorbing the heat optimally and radiating in the long wavelengths, so maximizing the greenhouse effect.
  • the side walls can be interlinked by a simple join, fitted together, glued or welded, which can be provided, for expansion effects, with a polymer seal.
  • the watertight sealed chamber can form a controlled-atmosphere enclosure.
