Description

  The present invention relates to a solar thermal hybrid panel including a solar power generation panel and a solar heat collector, and a solar system using the solar thermal hybrid panel.

  As a conventional technique, for example, as described in Japanese Patent Application Laid-Open No. 2004-198093, a rectangular solar cell panel and a heat collection panel are integrated in a superimposed state, and solar power generation and heat collection from sunlight are performed. There is known a hybrid solar heat collecting panel configured to execute the above. In the prior art, a rectangular heat collecting panel having the same size as the photovoltaic power generation panel is formed by combining a plurality of elongated heat collecting members.

  More specifically, when the dimensions of two sides orthogonal to each other among the four sides of the photovoltaic power generation panel are defined as the length dimension and the width dimension, the heat collecting member has the same length dimension as the photovoltaic power generation panel, It is formed as an elongated plate having a width dimension shorter than that of the photovoltaic power generation panel. In the prior art, a single heat collecting panel is formed by combining a plurality of heat collecting members in a state of being arranged in a flat plate shape so that end portions in the width direction are adjacent to each other.

JP 2004-198093 A (page 13, FIG. 9)

  In the prior art described above, a heat collecting panel having a size similar to that of the photovoltaic power generation panel is formed by combining a plurality of elongated heat collecting members in a flat plate shape. However, the outer dimensions of the photovoltaic power generation panel may include not only a general dimension of, for example, about 1.6 m × 0.8 m, but also a non-standard dimension. In addition, the shape of the photovoltaic power generation panel includes not only a quadrangle but also a non-standard shape such as a trapezoid. For this reason, in the prior art, when the size or shape of the photovoltaic power generation panel is out of the standard, it is necessary to manufacture a dedicated heat collector according to this, and there is a problem in that the efficiency of design and manufacturing decreases. is there.

  Also, as in the prior art, when a heat collection panel is formed by combining a plurality of heat collection members that extend only in the length direction of the photovoltaic power generation panel, the heat collection panel bends and deforms in the length direction due to its own weight. It becomes easy, and a clearance gap may arise between a photovoltaic power generation panel and a heat collecting panel. In order to avoid this state, for example, there is a problem that a reinforcing member such as a straight beam that presses the heat collecting panel against the photovoltaic power generation panel and keeps it in a close contact state is required.

  In addition, the heat collection panel thermally expands due to a rise in temperature during sunshine. However, if the heat collection member has a large dimension in only one direction, the thermal expansion amount tends to vary depending on the heat collection panel area, and the panel warp. There is a problem of inducing deformation such as bending. For example, when the heat collecting member is formed of an acrylic resin plate having a length of about 1.6 m, a width of 0.2 m, and a thickness of about 4 mm, and only the both ends in the length direction are supported, The maximum deflection of the member reaches 50 mm.

  The present invention has been made to solve the above-described problems, and can be easily adapted to various sizes and shapes of the photovoltaic power generation panel, and can generate power by suppressing deformation of the panel. And it aims at providing the solar thermal hybrid panel and solar system which can perform cooling efficiently.

  The solar thermal hybrid panel according to the present invention includes a plate-shaped photovoltaic power generation panel in which a plurality of photovoltaic cells that generate sunlight and generate power are arranged side by side, and within the area range of the back surface of the photovoltaic power generation panel. A plurality of solar heat collectors arranged side by side on the back surface side so as to fit in, and two or more solar heat collectors arranged in two directions parallel to and orthogonal to the back surface of the photovoltaic power generation panel, and a plurality of solar heat collectors And a heat medium passage through which the heat recovery medium flows, and a communication pipe communicating the heat medium passages of the plurality of solar heat collectors.

  According to the present invention, since a plurality of solar collectors are arranged in two directions along the back surface of the photovoltaic power generation panel, even when there are a plurality of types of photovoltaic power generation panels having different shapes or dimensions, This can be dealt with by changing the arrangement method and the number of arrangement items. That is, a plurality of types of solar thermal hybrid panels can be assembled using one type of solar heat collector as a common part. Therefore, in the entire product lineup of solar thermal hybrid panels, the number of parts such as solar heat collectors can be reduced, the manufacturing efficiency can be increased, and the manufacturing cost can be suppressed. In addition, since a plurality of solar heat collectors are arranged along two orthogonal directions, deformations such as warping and bending that occur in the solar power generation panel are suppressed, and the degree of adhesion between the solar power generation panel and the solar heat collector is improved. Can be increased. Thereby, a photovoltaic cell can be cooled efficiently and the power generation efficiency and power generation amount of a solar power generation panel can be improved.

In FIG. 2, the heat medium flow path 7 provided inside the solar heat collector 4 is shown in a transparent state. In the present specification, the solar heat collector is shown in a transparent state in the drawings used in the second and subsequent embodiments as necessary.

  The photovoltaic power generation panel 2 is formed in a rectangular plate shape (sheet shape) by using, for example, an insulating resin material. On the surface side of the photovoltaic power generation panel 2, as shown in FIG. 1, a plurality of solar cells 3 that generate power by receiving sunlight are provided. These solar cells 3 are formed, for example, as quadrangular cells having the same size, and are arranged in a lattice pattern along two sides orthogonal to each other among the four sides of the photovoltaic power generation panel 2. In other words, two or more solar cells 3 are arranged along the length direction and the width direction of the photovoltaic power generation panel 2 (left-right direction and up-down direction in FIG. 1).

  The solar heat collector 4 collects heat of the photovoltaic power generation panel 2 whose temperature rises due to sunshine by heat exchange. As shown in FIG. The collectors 4 are arranged side by side in a grid pattern in a close contact state. Each of the solar heat collectors 4 is composed of the same parts having the same outer shape, and has a structure as shown in FIGS. Here, FIG. 3 is a longitudinal sectional view showing a state in which the solar heat collector is broken in the direction perpendicular to the surface of the photovoltaic power generation panel in the first embodiment of the present invention. 4 is a cross-sectional view showing a state in which the solar heat collector is broken along the direction indicated by arrows AA in FIG. FIG. 5 is a single view of the cover plate of the solar heat collector as viewed from the direction indicated by arrows AA in FIG. 3 to 5, only the solar heat collector 4 is shown, and the communication pipe 10 and the like are not shown.

  The solar heat collector 4 is formed in a flat rectangular box shape as a whole, and includes a collector main body 5 and a cover plate 6. As shown in FIGS. 3 and 4, the collector main body 5 includes a frame-shaped portion 5A having a quadrangular frame shape that is open on both sides, a blocking plate portion 5B that closes one side of the frame-shaped portion 5A, and a frame-shaped portion. A plurality of ribs 5C projecting from the closing plate portion 5B inside 5A. The frame-like portion 5A, the blocking plate portion 5B, and the ribs 5C may be integrally formed of a material having high thermal conductivity (for example, a metal material or a resin material having relatively good thermal conductivity). .

  The lid plate 6 is attached to the opening of the collector main body 5 by means of, for example, adhesion, and closes the frame-like portion 5A from the side opposite to the closing plate portion 5B. In this state, each rib 5C is arranged so as to partition a space formed between the lid plate 6 and the closing plate portion 5B, and the heat medium flow path 7 bent and extended in a crank shape in this space. Forming. A heat recovery medium for recovering heat from the photovoltaic power generation panel 2 is circulated in the heat medium flow path 7. As the heat recovery medium, for example, brine such as water or propylene glycol is used.

  3 to 5, the cover plate 6 has a heat medium inlet 8 that opens at one end of both ends of the heat medium flow path 7 and the other of the heat medium flow path 7. A heat medium outlet 9 opening at the end is provided. The heat medium inlet 8 and the heat medium outlet 9 constitute a heat medium inlet / outlet for allowing the heat recovery medium to flow through the heat medium flow path 7.

  In addition, it is preferable to use a material having high thermal conductivity for the closing plate portion 5B that is in close contact with the back surface side of the photovoltaic power generation panel 2 in the solar heat collector 4, and the thickness of the closing plate portion 5B is the heat It is preferable to make it as thin as possible in order to increase conductivity. Moreover, it is preferable to use a lightweight material for parts other than the blocking plate portion 5B in the solar heat collector 4. Further, the thickness dimension of the solar heat collector 4 in the direction perpendicular to the cover plate 6 is preferably as thin as possible in order to reduce the weight.

  As shown in FIG. 2, the solar heat collector 4 configured as described above is arranged in a grid (matrix shape) on the back surface side so as to be within the area of the back surface of the photovoltaic power generation panel 2. Two or more pieces are arranged along the length direction and the width direction of the photovoltaic panel 2. In this state, the closing plate portion 5B of the collector body 5 of each solar heat collector 4 and the back surface of the photovoltaic power generation panel 2 are, for example, a sheet material such as a heat conductive sheet having a high thermal conductivity and soft, a rubber sheet, Alternatively, they are fixed in close contact (surface contact) with a material such as an adhesive or hot melt.

  Moreover, the area of the solar heat collector 4 on the back surface of the photovoltaic power generation panel 2 is formed to be equal to or less than the area of the solar battery cell 3. To describe a more specific configuration example, the size (vertical dimension and horizontal dimension) of the solar heat collector 4 having a quadrangular shape is set to a dimension value equal to or smaller than the vertical dimension and horizontal dimension of the four sides of the solar battery cell 3. Yes. According to this configuration, it is possible to reduce the weight of each solar heat collector 4 and to suppress warping, bending, and the like of the solar power generation panel 2 due to the weight of the solar heat collector 4.

  In addition, since the area where one solar heat collector 4 is bonded to the photovoltaic power generation panel 2 can be reduced, peeling or cracking of the bonding surface is caused by the thermal expansion and contraction of the solar heat collector 4. It can suppress and can stabilize the adhesion state of solar collector 4. In addition, by reducing the size of the solar heat collector 4, the flatness of the closing plate portion 5B and the cover plate 6 can be easily improved during manufacture. Thereby, the adhesiveness of the solar-heat collector 4 and the photovoltaic power generation panel 2 can be improved. Furthermore, for example, since one solar heat collector 4 can be arranged on the back side of one solar cell 3, each solar cell 3 can be efficiently and evenly cooled, The power generation efficiency of the power generation panel 2 can be improved.

  Further, a gap as a heat insulating structure having a dimension necessary for suppressing heat conduction between the solar collectors 4 adjacent to each other is provided. According to this configuration, heat exchange can be performed only between the solar battery cell 3 and the solar heat collector 4. That is, the heat absorbed by the solar heat collector 4 from the solar battery cell 3 is suppressed from being conducted to the adjacent solar heat collector 4, and the cooling efficiency of the solar battery cell 3 is reduced by the heat conduction between the solar heat collectors 4. Can be prevented. In the above description, the gap is illustrated as an example of the heat insulating structure. However, the present invention is not limited thereto, and various heat insulating structures including a heat insulating material or the like may be provided between the solar heat collectors 4. In addition, the solar cells 3 on the photovoltaic power generation panel 2 are spaced apart by a few millimeters so as not to contact each other. Therefore, in the solar cell 3 that contributes to an increase in the amount of power generation, only the solar cell 3 can be efficiently cooled by the solar heat collector 4 in close contact therewith, and the amount of power generation can be increased.

  Further, the heat medium inlet 8 and the heat medium outlet 9 of the different solar heat collectors 4 are communicated with each other via a communication pipe 10. The plurality of communication pipes 10 are connected to the heat medium inlet 8 and the heat medium so that the heat medium flow path 7 of each solar heat collector 4 provided in the solar power generation panel 2 constitutes one heat medium flow path as a whole. The medium outlet 9 communicates with the medium outlet 9. A heat medium that introduces a heat recovery medium from the outside of the solar heat hybrid panel 1 to the heat medium flow path 7 of each solar heat collector 4 is input to the heat medium inlet 8 that is the most upstream part of the entire heat medium flow path. A heat medium introduction pipe 11 is provided as an introduction passage. Further, the heat recovery medium flowing through the heat medium flow path 7 of each solar heat collector 4 is led out of the solar heat hybrid panel 1 to the heat medium outlet 9 which is the most downstream part of the entire heat medium distribution path. A heat medium outlet tube 12 is provided as a heat medium outlet passage.

  6 and 7 are configuration diagrams showing an example of a connection structure between the solar heat collector and the communication pipe in the first embodiment of the present invention. 6 (a) and 7 (a) show the configuration of the solar heat collector 4 and the like viewed from the back side of the photovoltaic power generation panel 2, and FIGS. 6 (b) and 7 (b) are diagrams. The block diagram which looked from the side in the state which decomposed | disassembled the cover plate 6, the communication pipe | tube 10, etc. in 6 (a) and FIG. 7 (a) is shown. The ends of the communication pipe 10 are connected to the heat medium inlet 8 and the heat medium outlet 9 of the solar heat collector 4 using means such as adhesion. Note that the connecting portions of the two may be connected by screwing or the like, or may be connected via a pipe connector such as a hose nipple. Further, the heat medium introduction pipe 11 and the heat medium outlet pipe 12 are connected to the heat medium inlet 8 and the heat medium outlet 9 in the same manner as the communication pipe 10.

  On the other hand, since the solar thermal hybrid panel 1 is often used in a state in which a plurality of photovoltaic power generation panels 2 are connected to each other, the individual photovoltaic power generation panels 2 are electrically connected to each other. A box-shaped connection terminal 13 is provided for connection. In addition, when the appropriate position of the connection terminal 13 changes with the specifications of a product, etc., you may change suitably arrangement | positioning of the solar-heat collector 4 and the communicating pipe 10. FIG. Moreover, it is not always necessary to arrange the solar heat collector 4 over the entire rear surface side of the photovoltaic power generation panel 2, even if there is a part where the solar heat collector 4 is not arranged other than the position of the connection terminal 13. Good.

  The solar thermal hybrid panel 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next. First, the solar thermal hybrid panel 1 constitutes a part of a solar system that performs solar power generation and solar heat recovery, and is installed on the roof of a house. Then, the heat medium circulation device of the solar system is connected to the heat medium introduction tube 11 and the heat medium outlet tube 12 of the solar heat hybrid panel 1. The heat medium circulation device circulates the heat recovery medium in each heat medium flow path 7 (heat medium flow path) of the solar heat hybrid panel 1 using a pump or the like.

  When sunlight is irradiated on the surface side of the photovoltaic power generation panel 2, photovoltaic power generation is performed by each solar battery cell 3, and the generated power is supplied to a distribution board or the like of the house via the connection terminals 13. Is done. At this time, the heat of the solar cells 3 whose temperature has increased due to sunshine or the like is absorbed by the heat recovery medium flowing through the heat medium flow path 7 of each solar heat collector 4, and the solar cells 3 are cooled. The heat recovery medium flows from the heat medium introduction pipe 11 into the heat medium flow path 7 of one solar heat collector 4, and flows through the heat medium flow paths 7 of all the solar heat collectors 4 through the respective communication pipes 10. After that, it flows out from the heat medium outlet pipe 12 and is returned to the heat medium circulation device. Thus, the heat medium circulation device recovers heat from the solar power generation panel 2 using the heat recovery medium, and the recovered heat is used for hot water supply or the like.

  On the other hand, in this Embodiment, as shown in FIG. 8, the other solar thermal hybrid panel 21 can be easily comprised by changing the arrangement method, the number of arrangement | sequences, etc. of the solar-heat collector 4. As shown in FIG. FIG. 8 is a configuration diagram showing a case where another solar thermal hybrid panel 21 having a nonstandard shape or size is configured in the first embodiment of the present invention. This figure has shown the state which looked at the photovoltaic power generation panel 22 from the back surface side. In the configuration example shown in FIG. 8, the solar power generation panel 22 is formed in a trapezoidal shape corresponding to the shape of the installation location of the solar thermal hybrid panel 21, for example. And on the back surface side of the photovoltaic power generation panel 22, a plurality of solar heat collectors 4 are arranged side by side along two directions orthogonal to each other, and arranged in a lattice shape so as to be substantially trapezoidal as a whole. Has been placed.

  As described above in detail, according to the present embodiment, a plurality of solar heat collectors 4 having a size smaller than that of the solar battery cell 3 are arranged side by side on the back surface side of the photovoltaic power generation panel 2. Thus, for example, as shown in FIGS. 2 and 8, even when there are a plurality of types of photovoltaic power generation panels 2 and 22 having different shapes or dimensions, by changing the arrangement and the number of the solar heat collectors 4 arranged, etc. The back surface side of the photovoltaic power generation panels 2 and 22 can be covered by the solar heat collector 4.

  Accordingly, a plurality of types of solar thermal hybrid panels 1 and 21 can be assembled using one type of solar heat collector 4 having the same outer shape as a common component. That is, it is not necessary to individually design and manufacture a plurality of types of solar heat collectors 4 corresponding to different types of solar power generation panels, and therefore, components such as solar heat collectors 4 in the entire solar heat hybrid panel product lineup. The number of points can be reduced, manufacturing efficiency can be increased, and manufacturing cost can be suppressed. Moreover, since the shape and dimensions of the solar thermal hybrid panels 1 and 21 can be easily matched to the installation space of the roof, etc., a solar system with a high degree of freedom of installation of the solar thermal hybrid panels 1 and 21 should be realized. Can do.

  Further, since the solar heat collectors 4 formed in a square panel shape are arranged and connected in a grid pattern, the photovoltaic power generation panel 2 is compared with the case of using a heat collecting member elongated in only one direction as in the prior art. It is possible to suppress deformation such as warping and bending. Thereby, the adhesion degree and thermal conductivity between the solar power generation panel 2 and the solar heat collector 4 can be increased, and the solar cells 3 can be efficiently cooled by the solar heat collectors 4. As a result, the temperature rise of the solar battery cell 3 can be suppressed and the power generation efficiency can be improved. In addition, since the photovoltaic cell 3 has the characteristic that power generation efficiency improves, so that the temperature of a cell is low with respect to the same amount of solar radiation, the power generation efficiency and power generation amount of the photovoltaic cell 3 are based on this characteristic. Can be improved.

  Further, on the back side of the photovoltaic power generation panel 2, a connection terminal 13 that electrically connects the plurality of photovoltaic power generation panels 2 is provided. The connection terminal 13 is a box-shaped protrusion and needs to be attached at a position suitable for connection between panels. On the other hand, in this Embodiment, arrangement | positioning of the solar-heat collector 4 can be set freely. Accordingly, the solar heat collector 4 can be easily arranged so as to cover the back surface side of the photovoltaic power generation panel 2 at another position while securing the arrangement space of the connection terminals 13 without performing special processing or the like. .

  Further, by reducing the size of the solar heat collector 4, the total flow path area of the heat medium flow path 7 extending along the back surface of the photovoltaic power generation panel 2 can be increased. Thereby, the cooling performance of the solar-heat collector 4 can be improved and the electric power generation efficiency of the photovoltaic cell 3 can be improved. In addition, by using the small solar heat collector 4, for example, the height dimension of the heat medium flow path 7 (that is, the separation dimension between the closing plate portion 5 </ b> B and the cover plate 6) is reduced, and the heat medium flow path 7. The cross-sectional area can be easily reduced. Thereby, the flow rate of the heat recovery medium flowing through the heat medium flow path 7 can be increased, the heat transfer performance can be improved, and the cooling capacity of the solar heat collector 4 can be improved.

  In the first embodiment, the closing plate portion 5B of the collector main body 5 of the solar heat collector 4 is in close contact with the back surface side of the photovoltaic power generation panel 2. However, the present invention is not limited to this, and may be configured as shown in FIG. 9, for example. FIG. 9 is a longitudinal sectional view similar to FIG. 3, showing a modification of the first embodiment of the present invention. In the solar heat hybrid panel 1 ′ of this modification, the heat medium inlet 8 and the heat medium outlet 9 of the solar heat collector 4 ′ are formed in the closing plate portion 5 </ b> B of the collector body 5, and the cover plate 6 is , Formed as a flat plate without holes. The solar heat collector 4 ′ is attached to the solar power generation panel 2 with the cover plate 6 in close contact with the back side of the solar power generation panel 2.

  According to the above modification, the cover plate 6, which has a high flatness and is a thin part, in the solar heat collector 4 can be brought into close contact with the back surface side of the photovoltaic power generation panel 2. That is, since the collector body 5 is formed by, for example, cutting or processing using a mold, warping may occur during processing molding, or the flatness of the closing plate portion 5B may be reduced. There is a limit to the conversion. On the other hand, since the cover plate 6 is easy to be accurately formed as a flat thin plate, it is possible to improve the adhesion and thermal conductivity to the photovoltaic power generation panel 2.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to FIGS.

Moreover, although the several solar heat collector 32 formed in the magnitude | size below the photovoltaic cell 3 is arranged in the grid | lattice form on the back surface side of the photovoltaic power generation panel 2, each solar heat collector 32 is as follows. The configuration shown in FIGS. 11 to 13 is provided.

  FIG. 11 is a longitudinal sectional view of the solar heat collector according to the second embodiment of the present invention as seen from the same position as in FIG. FIG. 12 is a cross-sectional view showing a state in which the solar heat collector is broken along the direction of arrows AA in FIG. FIG. 13 is a configuration diagram illustrating an example of a connection structure between a solar heat collector and a communication pipe in the second embodiment of the present invention. Moreover, Fig.13 (a) shows the block diagram which looked at the solar heat collector 32 grade | etc., From the back surface side of the photovoltaic power generation panel 2, FIG.13 (b) shows the cover plate 34 in FIG.13 (a), a communicating pipe | tube. The block diagram seen from the side in the state which decomposed | disassembled 10 grade | etc., Is shown.

  The solar heat collector 32 is formed in a flat rectangular box shape as a whole in substantially the same manner as in the first embodiment, and includes a collector main body 33 having a frame-shaped portion 33A, a blocking plate portion 33B, and a plurality of ribs 33C. And a lid plate 34 that closes the opening of the collector main body 33. Between the collector body 33 and the lid plate 34, for example, two heat medium flow paths 35 and 36 are formed by the ribs 33C, and these heat medium flow paths 35 and 36, as shown in FIG. Each bends and extends in a crank shape. Inside the collector body 33, a partition wall 33 </ b> D that partitions the heat medium flow paths 35 and 36 is provided. Further, the cover plate 34 is formed with four heat medium inlets / outlets 37 that open at both ends of the heat medium flow paths 35, 36, respectively. One of the two heat medium inlets / outlets 37 provided in each of the heat medium flow paths 35 and 36 serves as a heat medium inlet and the other serves as a heat medium outlet.

  In the state where the plurality of solar heat collectors 32 are arranged, the heat medium inlet / outlet 37 of two different heat medium flow paths among the heat medium flow paths 35 and 36 are connected via the communication pipe 10. Thereby, as shown in FIG. 13, the heat-medium flow paths 35 and 36 of each solar-heat collector 32 provided in the solar power generation panel 2 constitute one heat-medium distribution path as a whole. FIG. 13 illustrates a case where two solar collectors 32 are connected to explain the connection of the heat medium flow paths 35 and 36. In practice, as shown in FIG. One or more solar collectors 32 are connected. The heat medium inlet / outlet 37 is connected to the heat medium inlet / outlet 37 which is the uppermost stream portion of the entire heat medium circulation path, and the heat medium inlet / outlet 37 which is the most downstream portion of the entire heat medium circulation path is connected to the heat medium inlet / outlet 37. A medium outlet pipe 12 is connected.

  According to the present embodiment configured as described above, the following effects can be obtained. First, when the small solar heat collector 32 is used, the flow path resistance in the solar heat collector 32 is increased or the cross-sectional area of the heat medium flow paths 35 and 36 is reduced.

  First, the three-way valve 111 is provided in the middle of the heat medium introduction pipe 11, and the three-way valve 112 is provided in the middle of the heat medium outlet pipe 12. The three-way valves 111 and 112 are for branching the flow path of the heat recovery medium. In the present invention, a three-way joint may be used instead of the three-way valves 111 and 112. The bypass passage 113 connects the heat medium introduction pipe 11 and the heat medium outlet pipe 12 via the three-way valves 111 and 112.

  The pressure on / off valve 114 opens and closes due to a change in the inflow pressure of the heat recovery medium on the heat medium introduction pipe 11 side and a change in the outflow pressure of the heat recovery medium on the heat medium outlet pipe 12 side. More specifically, the pressure on / off valve 114 opens when the pressure difference between the inflow pressure and the outflow pressure of the heat recovery medium is out of a preset allowable range, and the pressure difference is equal to or less than the upper limit determination value. The valve is kept closed. The check valve 115 prevents the heat recovery medium from flowing backward from the heat medium outlet pipe 12 toward the heat medium introduction pipe 11.

In this state, the heat recovery medium supplied from the heat medium circulation device flows out from the heat medium introduction pipe 11 to the heat medium outlet pipe 12 via the heat medium flow path 7 of each solar heat collector 4. On the other hand, when the pressure difference between the inflow pressure and the outflow pressure of the heat recovery medium is out of the allowable range, the bypass mechanism 110 is operated and the pressure on-off valve 114 is opened.

  Here, as a case where the pressure difference deviates from the allowable range, for example, the pressure difference between the inflow pressure and the outflow pressure of the heat recovery medium is set in advance due to clogging, deterioration, or the like of the heat medium flow path 7 and the communication pipe 10. It is assumed that the upper limit judgment value is exceeded or the pressure difference becomes smaller than a preset lower judgment value because the communication pipe 10 is detached due to the clogging or the like and the heat recovery medium leaks.

That is, the heat recovery medium bypasses the solar heat hybrid panel 101 in which the pressure abnormality has occurred, and the heat medium circulation from the heat medium outlet pipe 12 without flowing through the solar heat collector 4 of the solar heat hybrid panel 101. Sent to the device (or other solar hybrid panel).

  The pressure on / off valve 114 may be a mechanical valve mechanism that opens and closes according to the pressure difference between the inflow pressure and the outflow pressure of the heat recovery medium, or is electrically opened and closed by the control device 121. An electromagnetically driven valve mechanism may be used. When an electromagnetically driven valve mechanism is used as the pressure on / off valve 114, the pressure difference between the inflow pressure and the outflow pressure of the heat recovery medium is detected by a pressure sensor or the like, and when the detected pressure is out of the allowable range, What is necessary is just to set it as the structure which opens the pressure on-off valve 114. FIG. The three-way valves 111 and 112 keep the heat medium introduction pipe 11 and the heat medium outlet pipe 12 open when the pressure of the heat recovery medium is normal, and the pressure of the heat recovery medium is out of the allowable range. In such a case, the heat medium introduction pipe 11 and the heat medium outlet pipe 12 may be closed in the middle so that these pipes communicate with the bypass passage 113.

  On the other hand, when the bypass mechanism 110 is activated to bypass the heat recovery medium, the control device 121 may be configured to notify the user of the solar system 120, the administrator, and the like of the operation information of the bypass mechanism 110. In this configuration, the control device 121 shows a specific example of notification means. According to the said structure, a user, an administrator, etc. can grasp | ascertain rapidly the abnormality of the solar thermal hybrid panel 101, and can cope with it.

In the following description, such two communication pipes 10 are referred to as “one set of communication pipes 10”.

  The bypass mechanism 141 circulates the heat recovery medium by bypassing the heat medium flow path 7 when the pressure in a part of the heat medium flow path 7 constituting the heat medium flow path is out of the allowable range. As in the sixth embodiment, three-way valves 142 and 142, a bypass passage 143, a pressure on-off valve 144, and a check valve 145 are provided.
