Description

Technical Field

[0002] Building-integrated photovoltaics (BIPV) is a technology that integrates solar power generation (photovoltaic) products into buildings. BIPV differs from simply attaching a photovoltaic system to a building. BIPV can be divided into two main categories: one is the integration of photovoltaic arrays with the building; the other is the integration of photovoltaic arrays with the building itself. Examples include photovoltaic tile roofs, photovoltaic curtain walls, and photovoltaic skylights. Of these two methods, the integration of photovoltaic arrays with the building is a common approach, especially integration with building roofs.

This building wall includes an energy storage wall capable of supplying heat and cooling to the interior, an air source heat pump, and an energy storage system. The energy storage wall is sequentially composed of an energy harvesting mechanism, an energy storage mechanism, and an energy conversion mechanism. The output end of the energy harvesting mechanism is connected in parallel to the air source heat pump and the energy storage system. The energy harvesting mechanism consists of a first support, a photovoltaic panel, a first fan, a second support, a first air cavity, and a switch AD. The energy storage mechanism... The structure consists of an insulation layer and an energy storage layer; the energy conversion mechanism consists of a second air cavity, a wall panel with a second fan and an air outlet; wherein: one end of the first bracket is connected to the photovoltaic panel via a first switch A, and the other end is connected to the energy storage mechanism via a third switch C; the photovoltaic panel is connected to the second bracket via a second switch B, and the second bracket is connected to the energy storage mechanism via a fourth switch D; the energy storage mechanism is connected to the energy harvesting mechanism via the first air cavity; the energy storage mechanism is connected to the wall panel of the energy conversion mechanism via the second air cavity.

[0004] However, the above solution requires switching operations via four AD switches to enable the photovoltaic panels to dissipate heat and supply air to the air source heat pump. This operation is cumbersome and prone to errors, affecting system stability and user experience. Utility Model Content

[0033] Example 1

[0034] like Figure 1-5 As shown, the present invention proposes a photovoltaic energy storage building wall, which includes a photovoltaic panel 2, a four-way valve 4, and an air inlet assembly;

[0035] A cavity 14 is provided on the inner side of the wall 1, and an energy storage layer for storing energy in the middle of the inner side of the cavity 14 is provided for use.

[0036] The photovoltaic panel 2 is installed on the outside of the wall 1; the side of the photovoltaic panel 2 and located in the cavity 14 are provided with an air supply component for conveying outside air into the cavity 14 and exchanging heat with the air source heat pump 3 during use.

[0037] The air inlet assembly is located inside the cavity 14 and inside the wall 1. The top of the air supply assembly is equipped with an air source heat pump 3 that is connected to the air supply assembly and heats and cools the air supplied by the air supply assembly when in use. The air source heat pump 3 is connected to an electric energy storage system (existing technology, not shown in the figure), and the electric energy storage system is connected to the air supply assembly and the air inlet assembly for power supply and control during use.

[0038] The four-way valve 4 is installed at the top of the wall 1 and is connected to the air source heat pump 3 and the cavity 14. It is used to deliver the air supplied by the air supply component to the air source heat pump 3 or to the outside when in use, so that the hot air is delivered to the air source heat pump 3 for use and the heat of the photovoltaic panel 2 is dissipated to the outside, so as to avoid the heat generated by the photovoltaic panel 2 from heating the energy storage layer when cooling is required.

[0039] In this embodiment, photovoltaic panel 2 generates electricity, while an air supply assembly delivers outside air into cavity 14. Heat exchange occurs along the surface of photovoltaic panel 2 within cavity 14, and the air is simultaneously supplied to air-source heat pump 3 via four-way valve 4 for heating or cooling. The air intake assembly is activated, allowing air from inside air-source heat pump 3 to flow into the room, thus regulating the indoor temperature. During air supply, air flows along the surface of the energy storage layer, enabling the storage of thermal or cold energy. When air-source heat pump 3 is turned off, the air intake assembly continues to supply outside or indoor air into cavity 14 and into the room. Internal emission: During the transportation process, the air comes into contact with the energy storage layer after energy storage for heating and cooling, thereby regulating the indoor temperature, improving energy utilization efficiency, reducing energy consumption, and achieving the purpose of energy conservation and emission reduction. At the same time, the air inlet of the air source heat pump 3 is sealed by the four-way valve 4, so that the cavity 14 is connected to the outside through the four-way valve 4. The outside air is discharged to the outside through the air supply component after passing through the photovoltaic panel 2, avoiding the occurrence of heat accumulation inside the cavity 14. Meanwhile, the air source heat pump 3 is directly connected to the outside through the four-way valve 4, so that the air inlet component generates suction, and the outside air is directly transported to the air source heat pump 3 for heating or cooling.

[0040] Example 2

[0041] like Figure 3-4 As shown, the photovoltaic energy storage building wall proposed in this utility model differs from that in Embodiment 1 in that the energy storage layer includes an insulation board 10 and an energy storage wall 11.

[0042] The energy storage wall 11 is installed in the middle of the cavity 14. The energy storage wall 11 is made of phase change energy storage material and is used to store thermal and cold energy during use.

[0043] The insulation board 10 is installed on the side of the energy storage wall 11 and close to the outer side of the wall 1. It is used to separate the photovoltaic panel 2 from the energy storage wall 11 during use, so as to prevent the heat generated by the photovoltaic panel 2 during use from heating the energy storage wall 11 when cooling is required, thus preventing the temperature of the energy storage wall 11 from rising.

[0044] In this embodiment, the energy storage wall 11 stores the hot and cold air delivered by the air source heat pump 3 to the air intake component in the cavity 14, so that the energy storage wall 11 can efficiently utilize the heat and cold energy in the cavity 14, and can heat and cool the air delivered by the air intake component, so as to adjust the indoor temperature to a comfortable range, improve the building energy utilization efficiency, and achieve the goal of energy conservation and emission reduction.

[0045] Example 3

[0046] like Figure 3 As shown, the photovoltaic energy storage building wall proposed in this utility model differs from that in Embodiment 1 in that the air supply component includes a first fan 5 and a first guide plate 8.

[0047] The first fan 5 is installed on the outside of the wall 1 and is connected to the cavity 14;

[0048] The first guide plate 8 is installed inside the cavity 14 and is located between the photovoltaic panel 2 and the insulation plate 10.

[0049] In an optional embodiment, there are multiple first guide plates 8, which are arranged alternately in the cavity 14. The outer side of the first guide plate 8, the inner side wall of the wall 1, and the side of the photovoltaic panel 2 and the energy storage wall 11 enclose a first air duct 9. The first air duct 9 is S-shaped. The first fan 5 and the four-way valve 4 are located at one end of the first air duct 9, respectively, and are used to move the outside air in the first air duct 9 through the first guide plate 8 during use, so that the photovoltaic panel 2 can be in full contact with the air and the heat generated by the photovoltaic panel 2 can be effectively transferred.

[0050] In this embodiment, by setting a first guide plate 8 inside the cavity 14 and forming an S-shaped first air duct 9 with the photovoltaic panel 2 and the energy storage wall 11 inside the cavity 14, when the first fan 5 delivers outside air into the cavity 14, the air flows along the first air duct 9 to the four-way valve 4. During the flow, the air comes into full contact with the surface of the photovoltaic panel 2, effectively absorbing the heat of the photovoltaic panel 2, thereby improving the heat exchange effect.

[0051] Example 4

[0052] like Figure 4-5 As shown, the photovoltaic energy storage building wall proposed in this utility model differs from that in Embodiment 1 in that the air intake component includes a ventilation pipe 6, a second fan 7, and a second guide plate 12.

[0053] The number of second guide plates 12 is multiple, and the multiple second guide plates 12 are arranged in an alternating manner. The multiple second guide plates 12, together with the side of the energy storage wall 11 and the inner wall of the wall 1, form a second air duct 13. The shape of the second air duct 13 is S-shaped.

[0054] The second fan 7 is installed on the inside of the wall 1 and is located at one end of the second air duct 13 and communicates with the cavity 14;

[0055] Ventilation duct 6 is installed on the inside of wall 1 and is connected to the second air duct 13 at the other end.

[0056] In this embodiment, by closing the ventilation duct 6 and starting the air source heat pump 3 to deliver cold or hot air into the cavity 14, the air flows through the second air duct 13 guided by the second guide plate 12, ensuring that the energy storage wall 11 is in full contact with the cold or hot air, thus absorbing thermal or cold energy. The cold or hot air is then exhausted into the room by the second fan 7, achieving indoor temperature regulation, further optimizing energy utilization, achieving energy saving and emission reduction effects, and improving living comfort. At the same time, the air source heat pump 3 is turned off and the ventilation duct 6 is opened, allowing indoor air to circulate in the cavity 14 and the room through the second fan 7. During the flow, the air flows through the second air duct 13 guided by the second guide plate 12, ensuring that the air in the second air duct 13 is in full contact with the energy storage wall 11 and performs heating or cooling operations. The air is then exhausted into the room by the second fan 7, effectively regulating the indoor temperature and achieving high efficiency and energy saving.

[0057] Example 5

[0058] like Figure 5 As shown, the photovoltaic energy storage building wall proposed in this utility model differs from embodiment four in that the ventilation pipe 6 includes a pipe body 61, a cover plate 62, and a latch 63.

[0059] The pipe body 61 is installed on the inside of the wall 1 and is located at one end of the second air duct 13 and connected to the second air duct 13;

[0060] The cover plate 62 is hinged to the bottom end of the tube body 61 and covers the end of the tube body 61;

[0061] The latch 63 is located at the top of the tube body 61 and the cover plate 62, which is the prior art and is only shown in the figure.

[0062] In this embodiment, by hingedly covering the end of the tube body 61 with the cover plate 62 and fixing the cover plate 62 with the latch 63, the port of the tube body 61 is closed, and the cover plate 62 is rotated and separated from the tube body 61 by the hinge, so that the indoor space is connected to the cavity 14. This makes the connection between the indoor space and the cavity 14 more flexible, facilitates the adjustment of indoor airflow according to actual needs, further improves the temperature control effect, and optimizes energy efficiency.

[0063] In this invention, power is generated by a photovoltaic panel 2. A first guide plate 8 is installed inside the cavity 14, forming an S-shaped first air duct 9 with the photovoltaic panel 2 and the energy storage wall 11. When the first fan 5 delivers outside air into the cavity 14, the air flows along the first air duct 9 towards the four-way valve 4. During this flow, the air fully contacts the surface of the photovoltaic panel 2, effectively absorbing its heat. The heated air is then transported to the air-source heat pump 3, where it is heated or cooled. A second fan 7 then draws in the heated or cooled air from the air-source heat pump 3, causing it to flow into the cavity 14 and be discharged into the room by the second fan 7, thus regulating the indoor temperature. Simultaneously, during the transport process... The second guide plate 12 directs airflow through the second air duct 13, ensuring full contact between the air and the energy storage wall 11. This allows the energy storage wall 11 to perform heat or cold storage. The side of the photovoltaic panel 2 is connected to the outside via the four-way valve 4, and the outside air is drawn in by the first fan 5 to exchange heat and cool the photovoltaic panel 2. The air is then discharged through the four-way valve 4. Simultaneously, the cover plate 62 is opened, or the air source heat pump 3 is connected to the outside via the four-way valve 4, allowing outside or indoor air to flow into the cavity 14 and fully contact the energy storage wall 11 along the second air duct 13. This allows the energy storage wall 11 to heat and cool the air, which is then discharged into the room by the second fan 7, regulating the indoor temperature. This achieves efficient energy utilization, improves living comfort, aligns with green building principles, and contributes to sustainable development.

[0064] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
