    OBJECT OF THE INVENTION
    The present invention relates to a system of utilization of the residual extraction air, for the generation of energy, based on the assembly on the conventional extraction outlet of the residual air that is produced in a building, of elements that allow generating energy to from the speed of the air flow in its extraction.
    The system of the invention falls within the technological sector corresponding to renewable energies, and more specifically associated with wind energy, using wind turbines, turbines, or any other element that takes advantage of the movement of air for power generation.
    The object of the invention is to take advantage of the residual extraction air flow, which is extracted by mechanical means, such as extractors, fans, air conditioning machines, etc., or natural, for the generation of energy in a clean and sustainable way, taking advantage the speed of the air generated in the extraction ducts.
    BACKGROUND OF THE INVENTION
    The vast majority of buildings have a system of forced or natural extraction of air from the ventilation of the building itself, the installation of air conditioning, waste from different industrial processes, or any other process that requires renewal or expulsion of air .
    So far, and despite having conducted an exhaustive search in the market, no system has been found to take advantage of said residual air, and although there are wind turbines as an energy production system, this is based on the Specifically, it has observed that in the ventilation ducts, extraction, air conditioning, etc. of the buildings, an air flow is generated with characteristics of speed, flow, density, etc., which has a great continuous and constant wind potential, which is discarded into the atmosphere without taking any advantage of it, generating however an important economic cost associated with its extraction.
    DESCRIPTION OF THE INVENTION
    The system that is recommended comes to solve the problem previously exposed, allowing to take advantage of the force or speed of any type of stale and extracted air in any type of building, for the generation of energy, allowing this energy to be consumed by the building itself , stored using different technologies for later use, or injected into the network.
    More specifically, the system of the invention is based on the fact that on the existing outlet in a building for the extraction of air from ventilation, air conditioning, waste from different industrial processes, or from any other process that requires renewal or expulsion of air, a duct is coupled, with the interposition of a coupling piece to adapt the extraction outlet to the referred duct, with the particular feature that said duct incorporates a wind turbine that can be of vertical axis or of horizontal axis, which can be operated by the force or velocity of the air flow that exits through the extraction outlet and therefore through the duct coupled thereto.
    If the existing extraction system is forced, the conduit, and of course the coupling piece between it and the extraction outlet, can be located after or before the extractor with which the extraction system in question conventionally counts.
    The duct in which the wind turbine is installed may have any type of shape and configuration, and will preferably be of smaller section than the extraction outlet so that in this way an increase in the speed of the air that is extracted is achieved and thus the wind turbine used may be of any type of existing in the market, an adaptation of them, or a model developed specifically for this system. In these last two cases, both the adaptation of an existing model and the development of a new wind turbine model will be considered included in the system described.
    The system will finally be completed with a covering element to prevent rainwater from entering.
    As is evident, one can be mounted in the duct that can be attached to the extraction outlet
    or several wind turbines, wind turbines and other elements that use the air as an energy generator, said elements being of vertical axis, horizontal axis, rotary and with any type of blade, blade, bowl, etc. technology, so that In some cases it may be the wind turbine itself, turbine or other element, which is coupled by itself, without the need to introduce it into the duct that can be attached to the extraction outlet.
    The power of wind turbines, wind turbines or other elements used will vary depending on the power of the existing air extractor, the flow, the speed, volume, density of the air flow and its composition, the distance between the extractor and wind turbine, as well as the shape of the extraction outlet.
    It should also be stated that different elements associated with the system can be coupled, provided that they help improve their efficiency, resulting in a single system since the energy would be generated by the same air flow.
    High performance is achieved based on the system of the invention, because the air flow is continuous and constant, without depending on the weather of the site.
    Also say that the system will be applicable to different types of existing extraction outlet: horizontal, vertical, lateral or oriented, both on facades and on decks or basement exits at street level, and can be applied to the air conditioning, ventilation or extraction exits natural or forced, and in general at any air outlet, of In the system as a whole, elements of access to the components are provided for maintenance, repair, cleaning and as many actions as are necessary for its correct operation.
    Measures are also foreseen to dampen the sound that the system could emit, if necessary, such as lining made of rock wool and other elements that help to soundproof the system whenever we exceed the sound level admitted by regulations, or depending on the use of the building or the requirements of the developer.
    Filters that improve the quality of the air extracted and emitted to the atmosphere may also be placed, provided that the regulations require it or simply at the initiative of the promoter.
    A previous study will be carried out consisting of a previous data collection and an analysis of each particular case, such as speed, density, air temperature, height, shape and section of the extraction outlet or duct, so that with that data The wind turbine and the most appropriate type of output will be considered to guarantee maximum performance, always respecting the volume of air to be extracted required by regulations.
    In any case, by means of the system of the invention and from a waste that is normally expelled into the atmosphere and discarded, energy can be obtained or generated to reduce the electricity bill and at the same time, if necessary, store the surplus applying different technologies, to be used later.
    The system can be complemented with a conventional wind generator, taking advantage of natural air currents, and it can work in addition to the described system, that is to say the wind turbine that is part of the system, complementing it and increasing the efficiency of the installation by adding to it The generated energy.
    Although it has been said that the duct in which the wind turbine is mounted will be smaller in diameter than the extraction outlet to achieve a higher air flow rate, however in certain cases where the speed of the element is not required of adaptation between the extraction outlet and the duct, it will be appropriate to allow the assembly of ducts of circular section, square section, or with any other configuration, in the same way that it will be coupled to any type, shape and section of the outlet Existing extraction.
    It will be possible to use anchoring and fastening elements of the system to solid and resistant walls or structures whenever necessary due to the stresses and vibrations that the wind turbine or the system itself could produce.

    In said extraction outlet (1) And as is conventional, the corresponding extractor (2) of the air for external discharge is mounted. It could be the case that there is no extraction device and the air outlet occurs naturally.
    Well, from these characteristics the system of the invention is characterized in that on the extraction outlet (1) the assembly of a conduit (3) is provided, with the interposition of an intermediate coupling piece (4) that allows the coupling between the extraction outlet (1) and the conduit (3), with the particularity that said coupling part (4) has a neck (4 ') for coupling to the conduit (3), which neck ( 4 ') of greater section than the extraction outlet (1) for coupling to a conduit (3) of greater section, or, as shown in the figures, be of smaller section than the conduit (3) so that it is of lower section than the extraction outlet (1) And thus favor or increase the output speed of the extraction air flow.
    The base of the coupling piece (4) between the conduit (3) and the extraction outlet (1), is also capable of presenting any geometric shape for adaptation to a complementary contour of the extraction outlet (1), being able to be of circular, oval, polygonal, regular or irregular section.
    The neck (4 ') of the coupling piece (4) between the conduit (3) and the extraction outlet (1), is also capable of presenting any geometric shape for adaptation to a complementary contour of the conduit (3), This can be any section: circular, oval, polygonal, regular or irregular.
    In any case, a wind turbine (5) is mounted in the duct (3), which can be of horizontal axis as shown in figures 1, 5 and 6, or of vertical axis referenced with (5 ') in figure 3 .
    The wind turbine used (5 or 5 ') may be of any type existing in the market, an adaptation thereof, or a model developed specifically for this system.
    In cases of vertical outlet, the duct (3) is complemented superiorly with a covering element (6) to prevent rainwater from entering.
    In the embodiment of Figures 3 and 4, where the wind turbine (5 ') is of vertical axis, said wind turbine (5') is complemented with a protector (7).
    15 In Figures 5 and 6 an embodiment is shown in which the extraction outlet (1) is horizontal, the duct (3) being mounted on a wall (8), being placed horizontally to house inside the wind turbine ( 5), that is, there are anchoring means (9) for fixing the duct (3) on a wall (8). These means of
    20 anchoring may also be necessary in cases of vertical output, depending on the power of the wind turbine to be installed and the stresses and vibrations it transmits.
    Measures can be taken to dampen the sound that the system could emit, if necessary, such as linings made of rock wool and 25 other elements that help soundproof the system.
    Filters that improve the quality of the air extracted and emitted into the atmosphere may also be placed.
