Description

Hybrid solar energy utilization system {HYBRID TYPE SOLAR ENERGY USING SYSTEM}

The present invention relates to a solar energy utilization system, and more specifically, by configuring a power generation module for generating electrical energy using solar light and a heat storage module for generating thermal energy using solar heat, for example, The present invention relates to a hybrid solar energy utilization system that can be efficiently used all year by switching to the power generation mode in the summer when electric energy is required for cooling and the heat storage mode in the winter when heat energy is required for heating.

Recently, due to the depletion of natural resources and the environmental and stability of thermal power and nuclear power generation, the solar energy utilization system that generates electric energy and heat energy using solar energy, which is a representative green energy, is developed. Research is actively underway.

Solar energy utilization system can be divided into solar power generator and solar heat storage device. The photovoltaic power generation device uses a solar cell made of GaAs, monocrystalline silicon, polycrystalline silicon, etc., which are expected to have a photoelectric effect. Specifically, the solar cells are arranged in the largest possible area to generate power through the photoelectric effect.

Such a photovoltaic device is low in installation cost and easy to install, but has a disadvantage of requiring a large area and having a very low photoelectric conversion efficiency. In addition, the conventional solar cell is discarded as it is, without utilizing heat obtained through direct sunlight, for example.

More specifically, the crystalline and a-Si thin-film solar modules each have a wavelength band of light that can be converted, and other wavelengths are incident to bring about a temperature increase of the solar module. Since the photovoltaic power generation efficiency has a characteristic of decreasing as the temperature increases, such a temperature increase of the photovoltaic module greatly reduces the power generation efficiency. For this reason, in general solar modules, only the light of the wavelength range that can be converted by the solar module is sent to the solar module by using an optical filter, and the light of the other wavelength band is blocked, thereby utilizing the solar heat corresponding to the light of the wavelength band other than the above. It can't be thrown away.

On the other hand, the heat storage device using solar heat is commonly used to heat the water or other materials with the incident solar heat, and to generate secondary power or use it for heating facilities in general, which has the disadvantage that the equipment is large and the efficiency is generally low. In order to increase efficiency, a device that can generate high temperature / high heat by condensing solar heat using a hemispherical reflector has been developed.In addition, by minimizing the amount of heat that is lost to the heat collected outside, It is being improved to have a structure that facilitates the transfer of heat for use.

However, as described above, in the conventional use of solar energy, sunlight and solar heat are converted into electrical energy or thermal energy through different energy converters. In particular, in the case of solar heat, solar hot water is collected to produce domestic hot water or high temperature is collected using a large-scale heat collecting system, and the engine is used to produce electricity by turning the engine.

Therefore, in the conventional case, in order to use solar energy efficiently throughout the year, it is necessary to install both a solar power generator and a solar heat storage device, each of which is composed of separate systems. There is also a problem that takes a lot.

The present invention has been made in view of the above, by configuring a power generation module for generating electrical energy using solar light and a heat storage module for generating thermal energy using solar heat, for example, cooling The purpose is to provide a complex solar energy utilization system that can be efficiently used all year by switching to power generation mode in summer when electric energy is needed to make a lot of energy and heat storage mode in winter when heat energy is required to be heated. .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, embodiments of the present invention illustrated below may be modified in various other forms, and the scope of the present invention is not limited to the embodiments illustrated below. The embodiments of the present invention described below are only provided to more completely explain the present invention to those skilled in the art.

In addition, in describing the embodiments of the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted and the same or corresponding configurations will be described in the drawings. The same reference numerals are used for the same reference numerals, and redundant descriptions are omitted.

As shown in FIG. 1, the hybrid solar energy using system according to an embodiment of the present invention includes a solar module 10, a light collecting unit 20, a heat storage unit 30, an optical filter folding unit 40, and the like. The control part 50 etc. are provided. In the figure, reference numeral 60 is an inverter, 70 is a flow control valve, 80 is a pump, 90 is a battery, and 100 is a sun.

The photovoltaic module 10 includes a plurality of solar cells 11 that receive light of a specific wavelength band of sunlight and convert light energy into electrical energy. The solar cell 11 may be formed of silicon, single crystal silicon, polysilicon, Cupper Indium Gallium Diselenide (CIGS), a compound semiconductor, or the like.

The solar cells 11 are arranged in a row at predetermined intervals on a predetermined substrate (not shown), and generate electric energy by receiving light of a specific wavelength band from the light incident from the sun 100. Here, the light of the specific wavelength band may be, for example, light of the 400 ~ 500nm wavelength band. Since light outside the specific wavelength band does not contribute to the production of electrical energy by the solar cell and serves to raise the temperature of the solar cell, it is necessary to prevent the light from being incident into the solar cell.

The light converging unit 20 is located between the columns of the solar cells 11 to reflect the light of the specific wavelength band and to condense the light to the solar cells 11, and transmits light of the wavelength band other than the specific wavelength band. Light in wavelength bands other than the wavelength band does not go to the solar cell 11 but is sent to the heat storage unit 30 described later below the light converging unit 20. Thereby, since the solar cell 11 is not heated by solar heat, the phenomenon that electrical energy conversion efficiency falls by the temperature rise of the solar cell 11 can be prevented.

As shown in FIG. 2, the light converging unit 20 includes a frame 21 made of a light transmissive material having a triangular longitudinal cross-sectional shape and an optical filter 25 and 25 ′ installed inside the frame 21. Include.

The frame 21 has a pair of cover glasses 22 and 22 'supported by an upper top support bar 23 and a lower side support bar 24 and 24' to form a triangular shape. One end of the solar cell 11 is supported by the side support bars 24 and 24 ', and the other end of the solar cell 11 is supported by the side support bars of the frame 21 adjacent to each other. .

The optical filters 25 and 25 'are disposed at predetermined intervals inside the pair of cover glasses 22 and 22', and an upper end thereof is supported by the top support bar 23, and the other end thereof is It is supported by the optical filter folding unit 40 mentioned later.

The optical filters 25 and 25 ′ reflect light of a specific wavelength band that can be converted into electrical energy by the solar module 10 among light incident from the sun 100, and light of a wavelength band other than the specific wavelength band, The light of the wavelength band causing the temperature rise of the solar module 10 is transmitted.

Accordingly, as will be described later in detail, the optical filters 25 and 25 'are covered with the cover glasses 22 and 22' inside the frame 21 as shown in FIGS. 5A and 5B by the optical filter folding unit 40. It may be positioned in parallel (first position) or vertically folded (second position). In this case, when unfolded as shown in FIG. 5A, light of a specific wavelength band of light incident from the sun may be applied to the optical filters 25 and 25. While reflected by ') and incident on the solar cell 11, light in a wavelength band other than the specific wavelength band passes through the optical filters 25 and 25' and is absorbed by the heat storage unit 30 thereunder.

As a result, in the power generation mode, light in the wavelength band that can be converted into electrical energy is collected and incident on the solo cell 11, while light in the wavelength band that raises the temperature of the solar cell 11 is not incident on the solar cell 11. Therefore, not only the production of more electrical energy is possible, but also the conventional problems due to the temperature rise of the solar cell 11, that is, the problem of reduction of energy conversion efficiency and shortening of life can be solved.

Meanwhile, although the frame 21 of the light collecting unit 20 has a triangular longitudinal cross-sectional shape in the illustrated example, the frame 21 is not specifically illustrated, but may be configured to have a circular longitudinal cross-sectional shape. . As described above, in the case of the frame having a circular longitudinal cross-sectional shape, since a separate support bar for supporting the cover glass constituting the frame 21 is not required, the effect of reducing the number of components and improving the assemblability can be expected. .

The heat storage unit 30 is positioned below the light collecting unit 20, and receives the light of all wavelength bands passing through the light collecting unit to convert the heat storage unit into heat energy. The heat storage unit 30 is an undercover 31, a heat absorbing medium 32 filled in the under cover 31, a heat transfer installed in the longitudinal direction so as to be immersed in the heat absorbing medium 32 in the under cover 31. And a heat storage tank 34 connected to one end of the member 33 and the heat transfer member 33.

The heat transfer member 33 may include an endothermic tube and a heat transfer medium filled in the endothermic tube, and the endothermic tube may be formed of a heat pipe or a copper pipe, but is not necessarily limited thereto. In addition, the endothermic tube is provided with a flow control valve 70 for controlling the flow rate of the heat transfer medium flowing through the endothermic tube.

In the heat storage unit 30 configured as described above, solar light passing through the light collecting unit 20 is absorbed by the heat absorption medium 32 and converted into thermal energy, and heat produced by the heat absorption medium 32 is obtained. Energy is transferred to the heat storage tank 34 through the heat transfer member 33 and is thermally stored.

In the heat storage tank 34, for example, heating water is stored, and the heating water is heated to a predetermined temperature by the heat energy transferred by the heat transfer member 33. The heat storage tank 34 is connected to a heating water circulation pipe 35 passing through the bottom of the house, and the heating water is supplied from the heat storage tank 34 by a pump 80 installed in the circulation pipe 35. Since it continues to circulate to the floor of the house, heating can be achieved. In FIG. 1, reference numeral 36 denotes an electric heater for auxiliary heating of heating water.

The optical filter folding unit 40 extends the optical filters 25 and 25 'to a first position in which light of the specific wavelength band is reflected by the solar cell 11 and condensed or includes light of the specific wavelength band. And folds the light in all wavelength bands to the second position to direct the heat storage unit 30. In this embodiment, the optical filter is unfolded to the first position in the power generation mode, and folded to the second position. Will be described in the heat storage mode.

3 and 4, the optical filter folding unit 40 is installed in the under cover 31 in a horizontal direction so as not to interfere with the heat transfer member 33, and is opposite to each other on both sides of the center portion. Lead screw 41 formed with a thread in the direction, a pair of moving rings 42, 42 'installed on the lead screw 41 and linearly moving inward or outward as the lead screw 41 rotates, The other end includes a connecting member 43 connected to the movable rings 42 and 42 'and a motor 44 for forward and reverse rotation of the lead screw 41 and the connecting screw 43 connected to the optical filters 25 and 25'. do.

Here, the lead screw 41 may be installed on both or one of the optical filters 25 and 25 ′, and the heat transfer member described above may be installed inside the frame 21 so as not to interfere with the lead screw 41. Is installed on.

The connecting member 43 is a hollow first member 43a, one end of which is connected to the movable rings 42 and 42 ', and one end of which is inserted into the hollow of the first member 43a and the other end of the optical filter. And a second member 43b connected to (25, 25 ') to compensate for changes in the length of the optical filters (25, 25') due to folding of the optical filters (25, 25 ').

In addition, although not shown in detail, the connecting member 43 includes a first member having one end connected to the moving ring and one end connected to the other end of the first member and the other end having an elastic member connected to the optical filter. The optical filter may be configured to compensate for a change in length of the optical filter due to folding of the optical filter. Here, the elastic member may be preferably used, such as a spring.

In the optical filter folding unit 40, as shown in FIG. 3, when the motor 44 rotates in the forward direction (clockwise direction), for example, the pair of screws located at both ends of the lead screw 41 rotates in the forward direction. The rings 42 and 42 'are moved inwards, so that the optical filters 25 and 25' connected to the moving rings 42 and 42 'are gradually folded. As indicated by the dashed-dotted line in 3, the optical filters 25 and 25 'are completely folded.

On the other hand, when the motor 44 rotates in the reverse direction (counterclockwise) in the above state, the pair of moving rings 42 and 42 'which are moved inward by the lead screw 41 rotates in the reverse direction are respectively the outer side. As a result, the optical filters 25 and 25 'are gradually unfolded and finally the optical filters 25 and 25' are completely unfolded as shown by solid lines in FIG.

Through the above process, it is possible to set the power generation mode in which the optical filters 25 and 25 'are unfolded in summer and the heat storage mode in which the optical filters 25 and 25' are folded in winter. 5B schematically shows a main part of the present invention in the heat storage mode. Referring to the operation of the hybrid solar energy using system according to the present invention will be described.

Hybrid solar energy utilization system according to the present invention, for example, in the summer to set the power generation mode for producing a lot of electricity required for cooling, while in the heat storage mode for producing a lot of heat required for heating in winter Can be set and used.

FIG. 5A illustrates the power generation mode. In the power generation mode, as illustrated, the optical filters 25 and 25 ′ are spread out in parallel to both cover glasses 22 and 22 ′ inside the frame 21. .

Accordingly, the light (dotted arrow) of a specific wavelength band that can be converted into electrical energy by the solar module 10 among the light incident from the sun 100 is reflected by the optical filters 25 and 25 ', and thus solar The cell 11 collects and sends a larger amount of light together with the light incident directly. On the other hand, light other than the specific wavelength band (solid arrow) passes through the optical filters 25 and 25 'and is sent to the lower heat storage unit 30 to be converted into thermal energy and stored.

Due to this action, a lot of light of a specific wavelength band that can be converted into electrical energy is incident on the solar cells 11, but less light of other wavelength bands is incident, thereby preventing overheating of the solar cell 11. The problem of reduced energy conversion efficiency and lifespan caused by overheating of the solar cell can be solved. At this time, since light of a specific wavelength band is collected and incident on the solar cell, more electric energy can be produced.

The electrical energy produced by the photovoltaic module 10 is used by being converted into alternating current through the inverter 60 and supplied to the house.

FIG. 5B is a diagram for explaining the heat storage mode. In the heat storage mode, as illustrated, the optical filters 25 and 25 ′ are folded to the center portion inside the frame 21.

Accordingly, sunlight of all wavelengths incident to the sun 100 passes through the light collecting unit 20 and is incident on the lower heat storage unit 30 to accumulate. Of course, even in this case, light incident from the upper side of the solar cell 11 is incident on the solar cell 11, but the amount of incidence thereof is smaller in the power generation mode due to the reflection action of the optical filters 25 and 25 '. In addition, although light of a specific wavelength band of light incident from above the light converging unit 20 is reflected in the power generation mode and is incident on the solar cell 11, in the heat storage mode, all light of the specific wavelength band is also collected. ) And penetrates into the heat storage unit 30 so that a lot of thermal energy can be produced.

The heat energy produced by the heat storage unit 30 is transferred to the heat storage tank 34 through the heat transfer member 33, whereby the heating water stored in the heat storage tank 34 can be used for heating. Here, by controlling the amount of the heat transfer medium by using the flow control valve 70 provided in the heat transfer member 33, it is possible to prevent the heating water temperature in the heat storage tank 34 from excessively rising.

As described above, the hybrid solar energy utilization system according to the present invention can be set to a power generation mode in summer to produce and supply a lot of electricity necessary for cooling, etc., and in winter to produce and supply a lot of thermal energy for heating. It can be used efficiently all year round.

In addition, in the power generation mode, it transmits light of a specific wavelength band incident to the solar cell, and transmits unnecessary light for electric energy production, thereby not only producing more electric energy but also lowering energy conversion efficiency caused by heating of the solar cell. It can solve the problem of shortening the life.

On the other hand, Figure 6 attached schematically shows a hybrid solar energy utilization system according to another embodiment of the present invention.

As shown in FIG. 6, the basic structure of the hybrid solar energy utilization system is the same as the embodiment of the present invention described above. However, this embodiment is different from the embodiment in that the configuration of the thermoelectric element 110 for recovering the heat energy emitted from the heat storage unit 30 as additional electrical energy is added.

Specifically, the heat storage unit 30 may have a case in which the hot water temperature rises above the limit temperature in summer, etc. In this case, the heat generating fan is operated to maintain a constant temperature. At this time, the stored heat energy is released, and electrical energy is consumed to operate the heat radiating fan.

In this embodiment, it is possible to produce electrical energy by using the thermoelectric element 110 to heat radiated as described above. The thermoelectric element 110 is connected to one end of the flow control valve 70 installed at the inlet side of the heat storage tank 34 of the heat transfer member of the heat storage unit 30, and the other end is connected to the outlet side of the heat transfer member. In addition, the thermoelectric element 110 is connected to the controller 50.

The thermoelectric element 110 refers to a device using various effects represented by the interaction between heat and electricity. In this embodiment, the thermoelectric element 110 converts heat into electrical energy to enable additional power generation.

The thermoelectric element 110 produces electrical energy by a Seebeck effect due to a temperature difference. The higher the temperature difference, the higher the energy conversion efficiency. In the present invention, since the thermoelectric element 110 is connected to the heat storage tank inlet side of the heat transfer member which is a high temperature part and the heat storage tank outlet side of the heat transfer member which is a low temperature part, it is very effective.

The other configuration is the same as the embodiment of the present invention described above, and the same reference numerals will be omitted detailed description. In addition, since the effects other than the effect of producing additional electrical energy by the thermoelectric element 110 as described above are the same as the embodiment of the present invention described above, a detailed description thereof will be omitted.

According to another embodiment of the present invention, since the heat discharged due to the overheating of the heat storage unit can be produced as an additional electric energy by using a thermoelectric element, the efficiency of electricity production using solar energy in the summer improves 30 to 40% or more You can.

In the above, the present invention has been described by way of example. It is to be understood that the terminology used herein is for the purpose of description and should not be regarded as limiting. Various modifications and variations of the present invention are possible in light of the above teachings. Therefore, unless otherwise indicated, the present invention may be practiced freely within the scope of the claims.
