Description
“Modulo fotovoltaico ed impianto termico per la produzione di acqua calda, integrati in una vetrocamera †⠀ œPhotovoltaic module and thermal system for the production of hot water, integrated in a double glazing â €
Il trovato si colloca nel settore dei sistemi per la produzione di energia alternativa e più in particolare ha per oggetto una vetrocamera al cui interno sono installati un modulo fotovoltaico e un collettore termico. The invention relates to the sector of systems for the production of alternative energy and more particularly relates to a double-glazing unit inside which a photovoltaic module and a thermal collector are installed.
Un modulo fotovoltaico à ̈ un dispositivo idoneo a convertire l’energia solare in energia elettrica mediante l’effetto fotovoltaico, ovvero il fenomeno fisico che si realizza quando un elettrone presente nella banda di valenza di un semiconduttore passa alla banda di conduzione quale conseguenza dell’assorbimento di un fotone sufficientemente energetico incidente sul materiale. A photovoltaic module is a device suitable for converting solar energy into electrical energy through the photovoltaic effect, that is the physical phenomenon that occurs when an electron present in the valence band of a semiconductor passes to the conduction band as a consequence of the absorption of a sufficiently energetic photon incident on the material.
Diversamente, un collettore solare, altrimenti denominato pannello solare termico, Ã ̈ un dispositivo atto alla conversione della radiazione solare in energia termica e al suo trasferimento verso un accumulatore per un uso successivo. On the other hand, a solar collector, otherwise known as a solar thermal panel, is a device suitable for converting solar radiation into thermal energy and transferring it to an accumulator for later use.
Come à ̈ noto, le prestazioni dei moduli fotovoltaici possono variare in base a diversi fattori fra i quali si citano: il rendimento dei materiali, la tolleranza di fabbricazione percentuale rispetto ai valori di targa, l’irraggiamento solare, la loro angolazione rispetto all’irraggiamento solare, la composizione dello spettro di luce ed infine, la temperatura di esercizio dei materiali che tendono ad “affaticarsi†in ambienti caldi. As is known, the performance of photovoltaic modules can vary based on various factors, including: the efficiency of the materials, the manufacturing tolerance percentage with respect to the plate values, the solar irradiation, their angle with respect to the Solar irradiation, the composition of the light spectrum and finally, the operating temperature of the materials that tend to “get tired” in hot environments.
In particolare, con riferimento a quest’ultimo fattore, à ̈ importante notare come il rendimento della cella e, di conseguenza, del modulo fotovoltaico, sia strettamente correlato alla temperatura di esercizio. La potenza di targa viene calcolata in condizioni standard (25°C), condizioni che solo raramente si verificano durante l’anno. Con temperature superiori, il rendimento del pannello diminuisce a causa delle proprietà intrinseche del semiconduttore e, infatti, l’aumentare della temperatura superficiale dei moduli fotovoltaici determina l’aumentare della resistività specifica con la conseguenza che la differenza di potenziale diminuisce. In particular, with reference to this last factor, it is important to note how the performance of the cell and, consequently, of the photovoltaic module, is strictly correlated to the operating temperature. The rated power is calculated in standard conditions (25 ° C), conditions that only rarely occur during the year. With higher temperatures, the efficiency of the panel decreases due to the intrinsic properties of the semiconductor and, in fact, the increase in the surface temperature of the photovoltaic modules determines the increase of the specific resistivity with the consequence that the potential difference decreases.
Scopo della presente invenzione à ̈ quello di fornire un modulo fotovoltaico che assicuri rendimenti costanti di potenza di targa anche all’aumentare della sua temperatura. The purpose of the present invention is to provide a photovoltaic module which ensures constant yields of rated power even when its temperature increases.
Un ulteriore scopo à ̈ quello di fornire un impianto termico che sia contenuto all’interno di una vetrocamera, del tipo normalmente utilizzato negli edifici per la realizzazione di finestre e che comprenda, un modulo fotovoltaico per la produzione di energia elettrica e un collettore termico per l’accumulo, in un boiler esterno, di energia termica. A further purpose is to provide a thermal system which is contained inside a double glazing, of the type normally used in buildings for the construction of windows and which comprises a photovoltaic module for the production of electricity and a thermal collector. for the accumulation of thermal energy in an external boiler.
Un ulteriore scopo, à ̈ quello di fornire un modulo per lo sfruttamento dell’energia solare perfettamente integrabile con la struttura di un edificio. A further purpose is to provide a module for the exploitation of solar energy which can be perfectly integrated with the structure of a building.
Il dispositivo, così come nel seguito descritto, presenta innumerevoli vantaggi fra i quali, in primo luogo quello di disporre di un unico impianto per la produzione, combinata e simultanea, di energia elettrica e acqua calda. The device, as described below, has innumerable advantages including, first of all, that of having a single plant for the combined and simultaneous production of electricity and hot water.
Inoltre, mediante l’adozione, per la realizzazione della lastra interna della vetrocamera, di un vetro basso emissivo, si ottiene un maggior isolamento termico degli ambienti interni dell’edificio. Furthermore, by adopting a low-emissivity glass for the realization of the internal sheet of the double glazing, a greater thermal insulation of the internal environments of the building is obtained.
Un ulteriore vantaggio consiste nella ridotta manutenzione a cui l’impianto deve essere sottoposto, infatti, l’inserimento dei moduli e dello scambiatore termico all’interno di un’intercapedine realizzata all’interno di una vetrocamera, pone i componenti di cui l’impianto à ̈ composto al riparo dagli agenti atmosferici. A further advantage consists in the reduced maintenance to which the system must be subjected, in fact, the insertion of the modules and the heat exchanger inside a cavity made inside a double glazing, places the components of which the system is made up protected from atmospheric agents.
Infine, ma non per importanza, un ulteriore vantaggio dell’impianto à ̈ il maggior rendimento ottenuto dai moduli fotovoltaici attraverso il raffreddamento delle celle raggiunto mediante il loro accoppiamento ad un collettore solare. Last but not least, a further advantage of the system is the higher yield obtained from the photovoltaic modules through the cooling of the cells achieved by coupling them to a solar collector.
Questi ed altri scopi come meglio appariranno dalla descrizione che segue, sono raggiunti dal modulo fotovoltaico ed impianto termico per la produzione di acqua calda, integrati in una vetrocamera, di cui alla presente invenzione, che viene descritto nel seguito in un’esecuzione preferita non limitativa di ulteriori sviluppi nell’ambito dell’invenzione, con l’aiuto della tavola di disegno allegata che illustra la seguente figura: These and other purposes, as will become clearer from the following description, are achieved by the photovoltaic module and thermal plant for the production of hot water, integrated in a double-glazing unit, according to the present invention, which is described below in a preferred embodiment not limiting further developments in the field of the invention, with the help of the attached drawing table which illustrates the following figure:
Figura 1: una vista in sezione del modulo integrato in una vetrocamera. Figure 1: a sectional view of the module integrated in a double-glazing unit.
Come illustrato nella tavola di disegno allegata, un modulo fotovoltaico ed un collettore termico sono integrati all’interno di una vetrocamera e costituiscono un modulo dell’impianto solare. As shown in the attached drawing table, a photovoltaic module and a thermal collector are integrated inside a double-glazing unit and constitute a module of the solar system.
Ciascun modulo 1 à ̈ formato, osservando la vetrocamera dal lato destinato ad affacciarsi esternamente all’edificio, da una prima lastra di vetro 2 ed una seconda lastra di vetro 4 fra le quali sono inserite cellule fotovoltaiche 3, da un collettore termico 5 inserito nell’intercapedine 6 e incollato sul lato interno della suddetta medesima lastra di vetro 4, mediante fascette fuse di EVA ed, infine, da una doppia lastra di vetro 7. Each module 1 is formed, observing the double glazing from the side intended to look outwards from the building, of a first glass plate 2 and a second glass plate 4 between which photovoltaic cells 3 are inserted, by a thermal collector 5 inserted in the interspace 6 and glued on the internal side of the aforementioned glass plate 4, by means of fused EVA strips and, finally, by a double glass plate 7.
L’inserimento del collettore termico 5 all’interno dell’intercapedine 6 ed in aderenza al lato interno della lastra di vetro 4 consente di raffreddare le celle fotovoltaiche 3 aumentandone il rendimento che, da prove di laboratorio, à ̈ stato quantificato in un incremento di più del 15% di produzione di energia elettrica nell’anno solare. The insertion of the thermal collector 5 inside the cavity 6 and adhering to the internal side of the glass plate 4 allows the photovoltaic cells 3 to be cooled, increasing their efficiency which, by laboratory tests, has been quantified in an increase of more than 15% in electricity production in the calendar year.
In un’ulteriore versione, conforme alla presente invenzione, Il modulo fotovoltaico à ̈ costituito da una coppia di lastre 2 e 4 fra le quali sono stratificate celle ad alta efficienza, ed un collettore termico, applicato esternamente in aderenza alla medesima lastra di vetro 4. In a further version, in accordance with the present invention, the photovoltaic module consists of a pair of plates 2 and 4 between which high efficiency cells are stratified, and a thermal collector, applied externally in adherence to the same glass plate. 4.
In questa seconda versione, la vetrata risulterà più leggera ed economica ed il suo uso sarà particolarmente idoneo alla realizzazione di coperture di serre, pensiline e tettoie. In this second version, the glazing will be lighter and cheaper and its use will be particularly suitable for the construction of greenhouses, canopies and canopies.
Entrambe le versioni dei moduli su descritti, raggiungeranno due obbiettivi: a) produrre energia elettrica per la conversione fotovoltaica tramite celle ad alta efficienza stratificate tra due lastre di vetro; b) produrre acqua calda per il trasferimento di calore da un collettore termico, inserito nella parte posteriore della vetrata o all’interno di una vetrocamera, ad un boiler esterno di accumulo. Both versions of the modules described above will achieve two objectives: a) to produce electricity for photovoltaic conversion by means of high-efficiency cells stratified between two glass plates; b) to produce hot water for the transfer of heat from a thermal collector, inserted in the rear part of the window or inside a double glazing, to an external storage boiler.
