Description

DESCRIZIONE DESCRIPTION

Descrizione dell’invenzione industriale dal titolo “Sistema di generazione di energia da solare termico” Description of the industrial invention entitled "Solar thermal energy generation system"

Premessa: Premise:

Il campo tecnico dell’invenzione è quello dell’energia alternativa e, più precisamente, riguarda lo sfruttamento dell’ irraggiamento solare. Attualmente il solare termico è quasi esclusivamente utilizzato per il riscaldamento di liquidi con successivo impiego del liquido riscaldato. Altra importante metodologia consiste nel concentrare i raggi solari in un punto mediante parabole così da ottenere una zona in cui si sviluppa una temperatura molto alta da poter poi essere impiegata in differenti modi. The technical field of the invention is that of alternative energy and, more precisely, it concerns the exploitation of solar radiation. Currently solar thermal is almost exclusively used for heating liquids with subsequent use of the heated liquid. Another important methodology consists in concentrating the solar rays in a point by means of parabolas so as to obtain an area in which a very high temperature develops which can then be used in different ways.

Il trovato si fonda sul principio della forza del gradiente di pressione per il quale i fluidi in ambiente con pressione non omogenea tendono a muoversi in modo da ristabilire l’equilibrio. The invention is based on the principle of the force of the pressure gradient for which the fluids in the environment with non-homogeneous pressure tend to move in order to restore equilibrium.

Un fluido riscaldato tende ad aumentare di volume; se è mantenuto in un ambiente chiuso, la pressione interna cresce in funzione della temperatura. A heated fluid tends to increase in volume; if it is kept in a closed environment, the internal pressure increases as a function of the temperature.

Il trovato: The found:

Il sistema è costituito da un volume chiuso con due aperture (1 e 5 in figura) , all’ interno è presente un fluido, nel caso più semplice si tratta di aria. Il volume è costituito da due camere adiacenti e comunicanti esposte ai raggi solari. Ad una delle apertura è collegata ima tubazione che finisce in una zona protetta dal sole (zona B) e, quindi, ad una temperatura naturalmente inferiore di almeno 15°C rispetto alla zona soleggiata (zona A). Nella zona in ombra è disposta una serpentina il cui volume interno è all’incirca pari a quello delle due camere esposte al sole. Per esaltare la differenza di temperatura le due camere sono verniciate di nero e la zona protetta è coperta da pannelli bianchi. In tali condizioni il fluido contenuto nelle due camere si surriscalda, la pressione interna delle due camere aumenta. Quando la differenza di pressione tra le camere esposte al sole e quella in ombra raggiunge un valore prestabilito si apre la valvola di sovrappressione indicata in figura ed il fluido espandendosi fuoriesce attraverso la tubazione (7). All’estremità della tubazione è installata una turbina (3) collegata ad una dinamo (4). Il fluido in pressione passa nella serpentina e quello nella serpentina viene spinto attraverso una valvola nelle due camere comunicanti. Quando si raggiungono le condizioni di equilibrio del sistema si chiude la valvola di sovrappressione. The system consists of a closed volume with two openings (1 and 5 in the figure), inside there is a fluid, in the simplest case it is air. The volume consists of two adjacent and communicating rooms exposed to the sun's rays. A pipe is connected to one of the openings and ends in an area protected from the sun (area B) and, therefore, at a naturally lower temperature of at least 15 ° C than the sunny area (area A). In the shaded area there is a serpentine whose internal volume is approximately equal to that of the two rooms exposed to the sun. To enhance the temperature difference, the two chambers are painted black and the protected area is covered with white panels. In these conditions the fluid contained in the two chambers overheats, the internal pressure of the two chambers increases. When the pressure difference between the chambers exposed to the sun and the one in the shade reaches a predetermined value, the overpressure valve shown in the figure opens and the fluid, expanding, escapes through the pipe (7). A turbine (3) connected to a dynamo (4) is installed at the end of the pipe. The pressurized fluid passes into the coil and the fluid in the coil is pushed through a valve into the two communicating chambers. When the equilibrium conditions of the system are reached, the overpressure valve closes.

Sulla tubazione di uscita è collocata una turbina che trascina una dinamo che a sua volta genera energia elettrica. On the outlet pipe there is a turbine that drives a dynamo which in turn generates electricity.

Il trovato offre alcuni significativi vantaggi: The invention offers some significant advantages:

- produce energia cinetica che si trasforma in energia elettrica - produces kinetic energy which is transformed into electrical energy

- fornisce un isolamento termico se installato sui solai - provides thermal insulation when installed on floors

ha una bassissima necessità di manutenzione has a very low maintenance requirement
