Description

System to generate energy.

The present invention relates to a system for generating energy that employs two independent circuits and a single solar thermal collector.

In particular, the system object of the invention is intended to generate electrical energy in one of the circuits and domestic hot water in the other, although it is included in the object of the invention to use, interchangeably, the two circuits for general electrical energy.

In the current state of the art, solar energy collectors (thermal or photovoltaic) associated with an energy circuit are already known. For example and among others, patent document P200501820 refers to a heating and sanitary hot water installation by means of solar thermal energy and patent document P9601377 refers to a mobile device for generating electricity in direct and alternating current by means of energy Solar photovoltaic.

An unsolved problem in known facilities is to take advantage of the large amount of excess energy that is captured and lost because it has to dissipate to prevent overheating of the collector. This problem is accentuated in geographical locations with especially hot climates.

The object of the invention is a generation system that also uses this surplus energy. It is characterized in that it consists of a single sensor with double grill and because said double grill feeds, respectively, a first circuit through which a first fl uid circulates and a second circuit through which a second fl uid circulates.

From this basic concept, any practical embodiments that do not alter, change or modify the proposed essentiality are included in the object of the invention.

In particular, it is included in the object of the invention that at least one of the circuits generates electrical energy (both circuits can generate electrical energy) and that this circuit that generates electrical energy has, in sequence:

-

means (for example a pre-tared valve) to regulate the outlet pressure of the fluid towards the means (for example a turbine) electricity generating

-

means (for example sand sedimented in water, within a condensate box) to fi lter the fluid at the outlet of said turbine. Additionally, and if the installation requires it, means (such as a drive pump) can be provided to supply fluid pressure on its return to the collector grill.

The fluid used is indistinct and accessory for the purposes of the invention, as well as the characteristics of the pressure regulating means, the driving means or the fi ltering / condensing means.

The advantages of this new system, according to the invention, are evident because the energy collected is maximized without complicating the structure of the collector or the environment.

Therefore, the recommended system to generate energy

To better understand the object of the invention, a preferred form of practical embodiment is shown in the drawings, susceptible to accessory changes that do not detract from its foundation.

Figure 1 represents a general scheme of the system object of the invention, with its main components in working position.

Figure 2 represents a general scheme of the system object of the invention, similar to Figure 1 but without double grill (P2) and with a single circuit (C1).

An example of practical, non-limiting embodiment of the present invention is described below. Other embodiments in which accessory changes are introduced that do not distort its basis are not ruled out at all; on the contrary, the present invention also encompasses all its variants.

The present invention is about a new system for generating energy.

Referring to the scheme in Figure 1, the system for generating energy object of the invention consists of a single sensor (C) with double grill (P1), (P2); wherein said double grill (P1), (P2), respectively, feeds a first circuit (1) through which a first fl uid (F1) circulates and a second circuit (2) through which a second fl uid (F2) circulates.

At least one of the circuits is a circuit (1) that generates electrical energy.

In accordance with the invention, and according to the embodiment shown, said circuit (1) has in sequence, at least, the following elements: means

(11) regulators of the output pressure of the fluid (F1) towards means (12) generating electricity and means (13) of fi ltration / condensation of the fluid (F1) on its return to the grill (P1) of the collector (C) .

Additionally, and if the installation needs require it, means (14) are provided that supply fluid pressure (F1) on its return to the grill (P1) of the sensor (C).

In accordance with the invention, and according to the embodiment represented, in particular:

-

the pressure regulating means (11) are, for example, one or more pre-tared valves;

-

the means (12) generating electricity are, for example, one or more turbines;

-

the fl uid (F1) is water, which is heated on the grill (P1) of the collector (C) and circulates in vapor form to the turbine (12) and returns in a liquid state when it circulates beyond the turbine (12);

-

the filtration / condensation means (13) are, for example, sand (131) sedimented in water

(132) the assembly going in a condensate box (133), and

-

to supply fluid return pressure (F1) if the installation requires it, the means

(14) employees are, for example, drive pumps.

In a specific example of embodiment of the fi ltration / condensation means (13), the condensate box (133) contains several compartments in which there is sand at different heights; so that the sand collects all the steam that overflows from the turbine

3 EN 2366308A1 4

(12) and it is cooling it at the same time as it condenses and thus descends, passing through communicating vessels, on the other side of the box (133) where it would eventually gain height until it reaches a tared point in which the water it would start to leave the box to continue on the circuit towards the grill (P1) where it would reheat and repeat the process. In addition, a running water inlet (134) is placed in the condensate box (133), so that the sand (131) also functions as an impurity filter and thus prevents further deterioration in the circuit due to unwanted remains Let them enter with the water.

In accordance with the invention, and according to the embodiment shown, the second circuit (2) through which the second fluid (F2) circulates is a closed circuit from the grill (P2) to an accumulator (21). For this closed circuit, for example, glycol circulates to generate domestic hot water in the accumulator (21).

In reference to the scheme in Figure 2, and in the event that the system only produces electricity, the collector does not have to incorporate the double grill (P2), but with other traditional collection systems such as, for example, the of fins, meanders or vacuum tubes, would work exactly the same.

The materials, dimensions, proportions and, in general, those other accessory or secondary details that do not alter, change or modify the proposed essentiality may be variable.

The terms in which this report is written are true and reflect the object described, and must be taken in its broadest sense and never in a limited way.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The present invention relates to a system for generating energy. Document D01 is considered to be the closest in the state of the art to the object of claim 1. In said document, to which the following reference numerals belong, is disclosed (page 1, lines 13-30; page 1, line 95 page 2, line 3; figures) a solar collector (9, 10) with double grill (17, 14) that feeds a first circuit (17) through which a first fluid and a second circuit (14) circulate through which A second fluid circulates. For the first circuit (17) circulates, for example, water (page 1, lines 120-127). A fluid circulates through the second circuit (14) (page 1, lines 108, 109) to generate domestic hot water (page 1, lines 25-30), assuming that it is implicit in a closed circuit from the grill (14 ) to an accumulator. As set forth in the preceding paragraph, claims 1, 5 and 7 are considered to be novel (Art. 6, LP 11/1986) and inventive activity (Art. 8, LP 11/1986). It is noted that in the invention of document D01 none of the circuits (17, 14) is intended for the production of electrical energy, although it is explicitly stated that the disclosed solar collector (9, 10) can be used in other applications (page 1, lines 25-27). It is therefore considered that claim 2 and its dependent claims 3, 4 and 6 are new (Art. 6, LP 11/1986). In relation to the inventive activity of claims 2-4, it is considered that one skilled in the art would clearly combine documents D01 and D02 reproducing the object of said claims in order to implement a circuit for the generation of electrical energy in the solar collector (9, 10) disclosed in document D01. Indeed, in document D02, to which the following numerical references belong, it is described (paragraphs [0037] - [0041]; figure 1) a circuit (10) for the generation of electrical energy from, for example, the heat generated by the sun. In said circuit (10), means regulating the pressure (56) of the fluid are arranged in sequence before entering electricity generating means (20, 28), filtering means (34), condensation means (42) and a pump of discharge (50) in the return (16) to the grille of the sensor (14). As set forth in the preceding paragraph, it is estimated that claims 2-4 lack inventive activity (Art. 8, LP 11/1986). As for the inventive activity of claim 6, no document of the prior art could be found in which the filtering and condensation functions were combined in a single device that included water-sedimented sand within a condensate box provided with an inlet of running water. Furthermore, it is considered that it would not be obvious to one skilled in the art to develop the object of claim 6 based on the combination of documents D01 and D02. Therefore, it is estimated that claim 6 does have inventive activity (Art. 8, LP 11/1986). State of the Art Report Page 4/4
