Description

MULTIFUNCTIONAL VENTILATION SYSTEM FOR A BUILDING.

DESCRIPTION

The present invention relates to a multifunctional ventilation system.

The invention in object in particular is advantageously used in the construction and/or renovation of buildings, especially in buildings located in historic centers and of significant historical-architectural interest, to which the following description will make explicit reference without thereby losing generality, to allow and facilitate the creation of correct forced or non-forced ventilation and/or aeration of the rooms and internal environments in general of the premises of these buildings without compromising the external aesthetic appearance of the relative external facades.

Even more advantageously, the system in question uses the window and French window openings both in the restructuring regime and in the new construction regime.

Currently, a deeply felt and relevant problem for those involved in building construction and in particular in the renovation of prestigious buildings in historic centers and/or in buildings with facades subject to architectural constraints, is the difficulty of being able to carry out structural and even non-structural changes structural in correspondence with the unalterable external facades of these buildings, especially to allow the assembly of air conditioning systems or equivalent systems, as well as for other ventilation functions necessary within a residential and non-residential building, works for which it is currently a must request specific authorizations from the administrations of the aforementioned buildings and, above all, from the competent public authorities for the control and supervision of the works.

It frequently happens that these authorisations, often with very complex and long-lasting obtaining procedures, are then denied, as the requested variations may lead to the need to make changes considered by the public authorities to be substantial, in particular on the external cladding or loadbearing walls that define the external facades of these buildings, such as for example the application and assembly of fixing and support brackets in order to allow the fixing and/or installation of the aforementioned air conditioning systems or new fixtures, even with openings new such as to significantly modify the aesthetic appearance of the external facades themselves.

Furthermore, even once the aforementioned authorizations to proceed have been obtained, the complexity of installing the aforementioned air conditioning systems and the aforementioned new fixtures remains high and such as to lengthen, often significantly, the execution times of the preparatory and completion works, not to mention the rise in operating costs.

The scope of the present invention is to solve the considerable problems mentioned above.

In particular, an aim of the present invention is to provide a ventilation system for rooms (civil dwellings, offices, etc.), of buildings and buildings of rapid and simple execution, with interventions that do not compromise the aesthetic appearance of the external facades of the same buildings, and which therefore do not generate difficulties during the request for specific authorizations from the competent administrations and authorities and which do not involve the remaking of the painting of the facade in case of damage caused by a new hole in the finishes and the external plaster of the facades.

Another scope of the present invention is to create a ventilation system for buildings which allows the temporal and constructive simplification of the preparatory and completion works for the installation of air conditioning systems or new fixtures (internal or external), with a significant reduction of costs.

A further scope is to improve the energy class of the building having the possibility of being able to install air-to-air conditioners of the latest generation that would otherwise not be able to be installed due to the ventilation difficulties described.

Another scope of the present invention is to provide a methodology for the multifunctional ventilation of buildings in general, especially in buildings located in historic centers and/or of significant historical-architectural interest, through which it is possible to carry out interventions, including maintenance, that do not modify and compromise the aesthetic appearance of the external facades of the same buildings, by means of a small and simple setback of the windows or French windows involved which does not involve a change in perspective by generating an air exchange opening in correspondence with the original external frame along its partial or total adjacent perimeter, managed in flows with the building components specified below. The structural and functional characteristics of the present invention and its advantages over the prior art will result even clearer and more evident from the underlying claims, and in particular from an examination of the following description, made with reference to the attached figures which show a preferred but not restrictive embodiment of the multifunctional ventilation system in question, in which:

Figure 1 is a perspective view of the system in question represented in the two-channel conformation with or without the use of the slit obtained on the new or pre-existing threshold of the window on which it can be applied and within whose system separators can be inserted for do not mix different ventilations;

Figure 2 is a perspective view of the system in question represented in the three-channel configuration without using the slit in the threshold which may or may not be necessary, and within the system of which separators can be inserted so as not to mix different ventilations;

Figure 3 represents a perspective view of the system in question which exploits the entire perimeter of the frame to obtain the greatest possible ventilation to be distributed according to the various required functions;

Figure 4 is a top plan view of an operating ducted component of the system in question in the case equipped with an openable grille for cleaning and disinfecting the aeration circuit;

Figure 5 is a front view of the system in question shown in Figure 1 with a general diagram for the possible inlet or outlet air flows which can also be modified with horizontal/vertical in lets/outlets in the case of ducted air conditioning systems with replacement outside airflow; Figures 6 and 7 are plan and partial vertical section, respectively, of the initial state before the intervention.

Figures 8 and 9 are respective plan and partially sectional views of the system shown in Figure 1 (state after the intervention with creation of the ventilation slots with grilles and opening in the old threshold).

With reference to the attached Figures from 1 to 9, S globally and schematically indicates a ventilation system suitable for being advantageously used in the construction and/or renovation of buildings, especially in a building located in a historic center and of significant historical-architectural interest, to which the following description will make explicit reference, or on taller buildings where the habitual opening of windows can be considered dangerous if not prohibited by law.

The system S comprises one or more support channels T for the same number of known relative fixtures "I" (internal or external) (such as windows, French doors and the like) and to be applied in correspondence with one or more openings of at least one external facade of said building of significant historical-architectural interest or new construction for the most relevant and advantageous application.

The cases with channles Ti, that is two channels TA and TB, or three channels TA, TB and TC are illustrated in the attached drawings, which can then also be used for fixing the new/old fixtures in addition to a ventilating band obtainable on the original threshold or for new installations as a window blocker integration .

Each channel Ti, which can be made preferably but not limited to iron or other equivalent rigid materials which globally also comply with the existing regulations for energy saving even with the possible addition of insulating materials suitable for the purpose, defines a building component which, single or combined with other components Ti forms a boundary structure to which at least one of the aforementioned frames "I" can be applied and is a channel-system with one, two or three sides connected or not by an upper crossbar, or an L or straight or reverse C-shaped element or shape of a square/rectangular band considering in addition the slot in the threshold below, each side adapted to be equipped with a ventilation slot opening towards the external environment.

Each side of the components Ti jointly or severally by a suitable slot obtainable on the plane of the threshold close to the external frame and in correspondence with the external slots of said channels is capable of generating an "external/internal ventilation perimeter otherwise not obtainable with a window or French door of normal design in the closed or open position.

A static clarification on the system: the aforementioned slotted Ti channels, in the case of refurbishments on old buildings, are generally installed in window or French-door compartments obtained on load-bearing walls with padding that have a "flared" internal part to better allow inside the diffusion of light where there is a load-bearing facade wall of larger dimensions than modern infill panels (generally thicknesses between 60-100 cm if not more). In these intrados there is generally a small upper vault with a function similar to a brick or stone platform which distributes the loads above on the portion of the load-bearing wall not affected by the openings of the window/French door compartments, exploiting the principles of the arch, or at the the perimeter of the vault itself with a vertical thrust component and a horizontal one which are composed by letting the load lines flow with trends that deviate from the intrados lines.

For this reason, the larger parallel and vertical dimensions with the window of the vertical channels to be installed for plant engineering purposes compared to an ordinary subframe can be tolerated from a static point of view, under restructuring conditions, using a rectangular section (or square or other according to best opportunity) which statically exploits as much as possible: a) the protrusion of the vaults of the window/French door openings in a direction parallel to the facade, b) the "flare" of the masonry which moves the discharge points of the upper vault away from the channel line as a result of a limited setback of the original window according to the ventilation and aesthetic requirements for the elevation itself.

This system S of channels Ti allows it to be mounted in correspondence with a special opening in the facade of said building, under renovation, recessed with an extension set back towards the inside of the facade of said building at a limited distance with respect to the opening itself, such that by slightly enlarging the depth of the external part of the intrados, it can allow the passage of air flows from said peripheral aeration cavities in such a way as not to alter the perspective design and not to require new holes on the prospectus itself.

The applications of this system are manifold as indicated at the beginning of the description and flexible according to the specific needs to be satisfied: for example the upper channel (if feasible because normally in the event of restructuring it could lead to either a static alteration of the loadbearing wall by affecting the upper vault or reducing to insufficient terms, from an urban point of view, the lighting engineering relationship between the fenestrated surface and the walkable surface of the room where the opening object of the intervention is located) can allow numerous types of simultaneous and non-simultaneous use (such as for example: collecting the expelled air of bathrooms, kitchens with unburnt outlets, carry out various forced and non-forced ventilations (such as, for example, the mandatory ventilation for cooking gas or ducted air conditioning systems, in some cases even the external air intake and the expulsion of external air of the ducted flows of the air conditioning etc.) according to the various needs, all to demonstrate that the system has a remarkable flexibility and adaptability of service.

To separate the incoming and outgoing flows inside the various channels, internal diaphragms will be used, thermally insulating or not, applied inside the ventilation channels or even in the residual under-window compartment according to convenience, which act as flow separators as well as in the residual compartment under the window of the frame "I" (in the case of windows only) it will be possible to install a condensing unit for traditional outdoor air conditioning with a special cabinet.

In addition to aesthetic functions, this cabinet also has acoustic and thermal insulation functions, which can be opened for maintenance and is equipped with suitable thermal air separators that configure the isolated separation of a plenum for the incoming external cooling air and another plenum for the heated air expelled from the condensing unit equipped with suitable regulation thermometers to which a possible forced extractor can be added (if necessary); or a newly developed condensing unit, currently being designed, conceived for a better use of this patent which, differently from all the machines currently on the market, will make it possible to exploit the cooling air flow inside the ducted window compartment on special manifolds or plenums generated with air separators that direct the flow of cooling air with an orientation at 90° with respect to current machines, or where the passage of the cooling air through special manifolds generated to collect/convey to the inside the ventilation channels/slots created in the system in question so that the cooling flow travels horizontally with respect to the direction of the window, inside the machine or the cabinet that may contain it.
