  • Natural ventilation is considered one of the main requirements in the design of homes and / or buildings, mainly in those buildings oriented to low energy consumption. Natural ventilation is a concept of air conditioning systems, which due to its characteristics has been called a passive system, and is considered essential for comfort inside rooms and for human well-being.
  • Passive air conditioning systems unlike conventional air conditioning systems (air conditioning systems and electric heaters, etc.), are characterized by their easy manufacture and very little maintenance required, in addition to their zero dependence on conventional energy , such as those of fossil origin.
  • the use of these systems contributes decisively to the reduction of greenhouse gas emissions, the saving and efficient use of non-renewable resources.
  • the issue of proposing new alternatives and improving existing ones to achieve comfort within the premises, and simultaneously reducing the consumption of conventional energy is one of the current challenges of our modern society.
  • renewable energies such as solar energy, wind energy and others, for use in passive ventilation systems in enclosures such as residential and non-residential buildings, industrial buildings, warehouses, classrooms, etc., are clear examples of this.
  • Simple ventilation When the air flow enters through one or more openings on one side of the room, for example, through a window.
  • Cross ventilation It is a concept used in Bioclimatic Architecture, to define a mode of ventilation of buildings. When air enters one side of a room through one or more openings and exits on the opposite side through one or more openings. Induced draft ventilation: In this case the buoyant force, due to thermal gradients is the main driving force, where the height of the shot is considered fundamental.
  • some types of passive ventilation devices can be mentioned, which are governed by the same physical principles, among them ⁇ Wind Towers, the Wall or Trombe Wall, the Ventilated Facade, the Solar roof with ventilation and the Solar fireplace, among others.
  • Wind Towers are appropriate in places where buildings are low-rise and where there is adequate wind speed, a wind tower collector is an architectural device of Persian tradition used for many centuries to provide natural ventilation and cooling inside of the buildings.
  • the Trombe Walls although they can be used to ventilate a room, their main function is to produce passive heating.
  • the Trombe Wall or Trombe-Michel Wall sensor is a sun-oriented wall or wall, preferably to the North in the southern hemisphere and to the South in the northern hemisphere, it is commonly constructed with materials that can store heat under the effect of thermal mass (such as stone, concrete, adobe or water), combined with an air space, a glass cover and vented holes forming a thermal solar collector.
  • the Ventilated Facades in addition to generating ventilation in a building, can be used to control, in some way and in some proportion, the light intensity and the noise level from the outside to the inside in a building.
  • the Solar Roofs with ventilation can be used in certain latitudes to passively ventilate an enclosure and at the same time they are part of the structure of the same enclosure or building.
  • a solar collector of the type Solar Roof with ventilation allows that in certain latitudes it is possible to use the roof surface to capture a certain amount of solar energy and at the same time can be used to ventilate a building and / or housing.
  • the Solar fireplace is very similar to the Trombe Wall collector, with the difference that the upper opening is used to expel hot air from the channel to the outside and in this way there is ventilation of the enclosure to which it is attached.
  • the solar chimney is integrated into the building with an orientation in such a way that it takes full advantage of the incident solar energy, in order to heat the absorber plate and therefore the air inside the canal.
  • a Solar fireplace can be defined as an elongated ventilated cavity, usually located in the sunniest part of a house and / or building. Its main function is to remove the volume of air in an enclosure, with the simple purpose of ventilating the home to improve air quality, or, with the additional purpose of generating thermal comfort conditions if the air entering the Room is pre-conditioned, either passively or actively. Under normal operating conditions, a Solar Chimney receives radiant energy from the Sun, which affects the absorption plate through a glass cover.
  • a simple classification of these systems by their application is: Solar chimneys of daytime use (with metal absorber plate), and chimneys of night use (with absorber plate of great thermal storage capacity).

Abstract

La présente invention concerne une stratégie de ventilation et/ou de chauffage passif pour des logements, des bâtiments industriels et/ou des constructions, au moyen de l'utilisation d'un récepteur ou chauffage solaire de l'air. L'invention produit également une stratégie de ventilation naturelle de logements, de bâtiments industriels et/ou de constructions, au moyen de l'utilisation de deux systèmes passifs couplés en série, un chauffage solaire et un extracteur d'air atmosphérique du type dynamique. L'extraction d'air dans le nouveau système mixte est effectuée par un double effet maximisé, l'effet solaire-thermique et l'effet dynamique-éolien. Le couplage du chauffage solaire à l'extracteur atmosphérique s'effectue au moyen d'une réduction du type ajutage trapézoïdal ayant une géométrie et des dimensions caractéristiques. Le système dans son ensemble doit être installé de telle sorte qu'il favorise la captation de l'énergie solaire incidente sur sa plaque d'absorption pour qu'il assure le meilleur chauffage et la meilleure récupération.En même temps, il est également pratique qu'il soit installé à une hauteur suffisante pour tirer profit de l'énergie du vent et pouvoir faire tourner de manière appropriée l'extracteur d'air dynamique. Le couplage des deux dispositifs (le chauffage solaire et l'extracteur atmosphérique du type dynamique) par l'intermédiaire d'une réduction du type ajutage ayant des dimensions caractéristiques, permet d'obtenir un effet amélioré, du fait que l'extraction d'air est maximisée dans des bâtiments et/ou des constructions jusqu'à quatre fois plus que ce que les deux systèmes séparés feraient, comme cela a été le cas jusqu'à présent. On a donné à ce nouveau système le nom de cheminée solaire-éolienne.
