Abstract
Description
Technical Field
[0001] This invention relates to a photovoltaic air conditioning window. Background Technology
[0002] Existing building windows are mainly used to achieve functions such as lighting, ventilation, and basic enclosure and isolation; they do not have the ability to actively regulate indoor temperature. With the continuous improvement of building energy conservation requirements, some window products have begun to improve thermal insulation performance through methods such as hollow structures, coated glass, or thermal insulation materials. However, these types of windows can still only passively reduce heat transfer and cannot actively regulate indoor ambient temperature.
[0003] In practical building applications, indoor temperature regulation typically relies on air conditioning systems, especially in residential and public buildings, where wall-mounted air conditioners, cabinet air conditioners, or central air conditioning systems are commonly used. While these air conditioning systems can achieve cooling or heating, they generally suffer from high energy consumption and strong dependence on external power. Furthermore, the installation process requires additional piping, power lines, and equipment installation space, which not only increases construction and maintenance costs but also, to some extent, damages the building facade or occupies indoor and outdoor usable space, hindering the simplification and integrated design of the overall building structure.
[0004] Meanwhile, with the development of photovoltaic power generation technology, some buildings have begun to try applying photovoltaic modules to roof or curtain wall structures to achieve solar power generation and auxiliary power supply. However, existing building-integrated photovoltaic (BIPV) solutions mostly focus on the power generation function itself, and the photovoltaic modules and building envelope often only form a simple superposition relationship, failing to effectively integrate with indoor environmental regulation functions. Energy utilization efficiency and functional integration still need to be improved.
[0005] Therefore, there is currently a lack of a window structure solution that can effectively integrate photovoltaic power generation with the window structure without occupying additional building space, and further utilize the generated electricity to achieve indoor temperature regulation. It is difficult to simultaneously meet the needs of building energy conservation, structural integration and user comfort. Summary of the Invention
[0006] To address the aforementioned problems, this invention provides a photovoltaic air conditioning window, which effectively overcomes the shortcomings of existing technologies.
[0007] This invention is achieved through the following technical solution: a photovoltaic air conditioning window, comprising: A window structure, comprising a window frame and a light-transmitting window body installed within the window frame; A photovoltaic power generation layer is disposed on the outside of the light-transmitting window, and the photovoltaic power generation layer is used to convert solar energy into electrical energy; A semiconductor cooling system is embedded in the window frame, and the semiconductor cooling system includes at least one semiconductor cooling chip. A ventilation and heat dissipation system is configured in conjunction with the structure of the semiconductor refrigeration system to dissipate heat and circulate air during the operation of the semiconductor refrigeration chip; The photovoltaic power generation layer is electrically connected to the semiconductor refrigeration system so that the photovoltaic power generation layer supplies power to the semiconductor refrigeration system, enabling the semiconductor refrigeration chip to achieve cooling or heating inside the window when energized, thereby regulating the indoor temperature.
[0008] As a preferred technical solution, the photovoltaic power generation layer is a semi-transparent photovoltaic glass, and is set as the outer layer structure of the light-transmitting window.
[0009] As a preferred technical solution, the semi-transparent photovoltaic glass is cadmium telluride semi-transparent photovoltaic glass.
[0010] As a preferred technical solution, the semiconductor cooling system includes multiple semiconductor cooling chips, which are spaced apart along the length or height direction of the window frame.
[0011] As a preferred technical solution, the ventilation and heat dissipation system includes heat sinks that are in thermal contact with the semiconductor cooling chip, and a DC fan for driving airflow.
[0012] As a preferred technical solution, the system also includes an energy storage system, which is electrically connected to the photovoltaic power generation layer and is used to store excess electrical energy generated by the photovoltaic power generation layer and to supply power to the semiconductor cooling system when there is insufficient sunlight.
[0013] As a preferred technical solution, the system also includes a controller, which is electrically connected to the photovoltaic power generation layer, the semiconductor refrigeration system and the energy storage system respectively, and is used to adjust the working state of the semiconductor refrigeration system according to the indoor and outdoor temperature difference.
[0014] As a preferred technical solution, the heat sink includes a first heat sink and a second heat sink, and the DC fan includes a first DC fan and a second DC fan. The first heat sink is installed at the cold end or the hot end of the thermoelectric cooler, and the first DC fan is installed on the first heat sink. The second heat sink is installed at the cold end or the hot end of the thermoelectric cooler, and the second DC fan is installed on the second heat sink.
[0015] As a preferred technical solution, the controller is configured to switch the working mode of the semiconductor cooling system according to the real-time power generation of the photovoltaic power generation layer, the remaining power of the energy storage system, and the indoor and outdoor temperature difference. The working mode includes at least one of the cooling mode, heating mode, and standby mode, so as to achieve adaptive matching between photovoltaic power generation and temperature regulation requirements.
[0016] As a preferred technical solution, the first DC fan and the second DC fan are independently set to correspond to the cold end side and the hot end side of the semiconductor refrigeration chip, respectively, and can be started, stopped or have their speed adjusted independently under the control of the controller, so as to realize the separate control of the heat exchange intensity of the cold end side and the hot end side.
[0017] The beneficial effects of this invention are: This invention integrates a photovoltaic power generation layer, a semiconductor cooling system, and a ventilation and heat dissipation system into the window structure, so that the window not only has the function of lighting, but also has the ability to generate electricity and regulate temperature, thus avoiding the problem of the single function of traditional windows and improving the comprehensive use value of the window.
[0018] This invention converts solar energy directly into electrical energy and powers a semiconductor refrigeration system by setting a photovoltaic power generation layer on the outside of the window, thereby enabling the local acquisition of the energy required for temperature regulation. This effectively reduces dependence on the municipal power grid or external power sources and helps reduce energy consumption during building operation.
[0019] The semiconductor cooling system and ventilation and heat dissipation system of the present invention are embedded inside the window frame, forming an integrated structure with the window body. There is no need to set up separate air conditioning equipment or reserve additional installation space, which avoids the problem of traditional air conditioning equipment occupying indoor and outdoor space and helps to maintain the cleanliness of the building facade and interior space.
[0020] The semiconductor cooling chip of the present invention can realize cooling or heating functions when energized, and can adjust the indoor temperature according to actual needs. It is suitable for use scenarios in different seasons and under different environmental conditions, thus improving the applicability of the window.
[0021] This invention, by setting up a ventilation and heat dissipation system, can dissipate heat and circulate air in a timely manner during the operation of the semiconductor cooling chip, which helps to improve heat exchange efficiency, reduce local overheating, and thus improve the overall system's operational stability and service life.

[0024] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0025] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0026] like Figures 1-4 As shown, a photovoltaic air-conditioning window of the present invention includes a window structure, a photovoltaic power generation layer, a semiconductor cooling system 3, a ventilation and heat dissipation system, an energy storage system, and a controller 4. The window structure serves as the overall load-bearing foundation and includes a window frame 1 and a light-transmitting window installed within the window frame 1. The window frame 1 is used to fix and support the various functional components, while the light-transmitting window is used to meet the building's lighting requirements and provide an installation foundation for the photovoltaic power generation layer.
[0027] The photovoltaic power generation layer is set on the outside of the light-transmitting window and serves as the outer structure of the light-transmitting window. The photovoltaic power generation layer uses semi-transparent photovoltaic glass, which enables it to have solar power generation capabilities while still meeting the light transmission requirements of the window.
[0028] In this embodiment, the semi-transparent photovoltaic glass is preferably cadmium telluride semi-transparent photovoltaic glass. This type of photovoltaic glass has good power generation efficiency and light transmission performance, making it suitable as a functional integrated component of building windows. When the photovoltaic power generation layer is exposed to sunlight, it converts solar energy into electrical energy and outputs it.
[0029] The semiconductor cooling system 3 is embedded inside the window frame 1, forming an integrated design with the window structure, thus avoiding the problem of external devices occupying indoor or outdoor space. The semiconductor cooling system 3 includes at least one semiconductor cooling chip 33. In a preferred embodiment, the semiconductor cooling system 3 includes multiple semiconductor cooling chips 33, which are spaced apart along the length or height of the window frame 1. This allows for flexible arrangement according to window size and cooling requirements, improving the uniformity and efficiency of overall temperature regulation. When energized, each semiconductor cooling chip 33 forms a cold end on one side and a hot end on the other, thereby achieving a cooling or heating effect.
[0030] The ventilation and heat dissipation system is structurally configured in conjunction with the semiconductor cooling system 3 to dissipate heat and circulate air during the operation of the semiconductor cooling chip 33. In this embodiment, the ventilation and heat dissipation system includes heat sinks and DC fans, wherein the heat sinks include a first heat sink 32 and a second heat sink 34, and the DC fans include a first DC fan 31 and a second DC fan 35.
[0031] The first heat sink 32 is installed on the cold end or hot end of the semiconductor cooling chip 33, and the first DC fan 31 is installed on the first heat sink 32. The operation of the first DC fan 31 promotes airflow and accelerates the heat exchange on the corresponding side. The second heat sink 34 is installed on the cold or hot end of the semiconductor cooling chip 33, and the second DC fan 35 is installed on the second heat sink 34 for heat dissipation or cold exchange on the other side.
[0032] By coordinating the first heat sink 32, the second heat sink 34, and the corresponding DC fan, the heat exchange process on both sides of the semiconductor cooling chip 33 becomes more stable, which helps to improve the cooling or heating efficiency and avoids affecting the stable operation of the system due to local overheating.
[0033] The photovoltaic power generation layer is electrically connected to the semiconductor refrigeration system 3. The photovoltaic power generation layer supplies power to the semiconductor refrigeration system 3, enabling the semiconductor refrigeration chip 33 to achieve cooling or heating inside the window when energized, thereby regulating the indoor temperature.
[0034] To further enhance the system's adaptability and continuous operation capability, this embodiment also includes an energy storage system, which is electrically connected to the photovoltaic power generation layer and is used to store excess electrical energy generated by the photovoltaic power generation layer.
[0035] When there is insufficient sunlight or no power generation at night, the energy storage system can supply power to the semiconductor cooling system 3, thereby ensuring the normal operation of the photovoltaic air conditioning window under different environmental conditions.
[0036] In addition, this embodiment also includes a controller 4, which is electrically connected to the photovoltaic power generation layer, the semiconductor cooling system 3 and the energy storage system respectively.
[0037] The controller 4 is used to acquire indoor and outdoor temperature difference information and adjust the working state of the semiconductor refrigeration system 3 according to the indoor and outdoor temperature difference, thereby realizing reasonable control of the cooling or heating intensity, so that the photovoltaic air conditioning window can ensure comfort while taking into account energy consumption control and system stability.
[0038] The photovoltaic air-conditioning window in this embodiment integrates photovoltaic power generation, semiconductor refrigeration, and window structure into one unit. Without occupying additional building space, it achieves the coordinated operation of window lighting, energy acquisition, and indoor temperature regulation functions, and features a compact structure, high functional integration, and strong applicability.
[0039] In this embodiment, the controller 4 is not only used to control the start and stop of the semiconductor cooling system 3, but is also configured to comprehensively judge the power generation status of the photovoltaic power generation layer, the power status of the energy storage system, and the indoor and outdoor temperature difference.
[0040] Specifically, the controller 4 can obtain the power generation information of the photovoltaic power generation layer in real time, and at the same time obtain the remaining power information of the energy storage system. When the power generation of the photovoltaic power generation layer is high and the energy storage system has sufficient power, the controller 4 controls the semiconductor cooling system 3 to enter the cooling mode or heating mode to meet the indoor temperature regulation needs. When there is insufficient sunlight, the power generation is low, and the energy storage system's power drops to a preset threshold, the controller 4 can control the semiconductor cooling system 3 to enter standby mode or reduce its operating power, thereby achieving adaptive matching between photovoltaic power generation capacity, energy storage status, and temperature regulation requirements, improving the overall energy utilization efficiency of the system, and extending the system's continuous operating time.
[0041] Furthermore, in this embodiment, the first DC fan 31 and the second DC fan 35 in the ventilation and heat dissipation system are respectively disposed on the cold end side and the hot end side of the semiconductor cooling chip 33, and the two are structurally independent of each other.
[0042] The controller 4 is electrically connected to the first DC fan 31 and the second DC fan 35 respectively, so that the first DC fan 31 and the second DC fan 35 can start and stop independently or adjust their speed independently under the control of the controller 4.
[0043] When the semiconductor cooling system 3 is in cooling mode, the controller 4 can adjust the operating status of the first DC fan 31 and the second DC fan 35 according to the temperature changes of the cold end side and the hot end side, so as to enhance the heat exchange efficiency of the corresponding side. When the semiconductor cooling system 3 is in heating mode or low-load operation, the controller 4 can reduce or turn off the speed of one or both DC fans, thereby achieving separate control of the heat exchange intensity on the cold end and hot end, further improving the stability and energy efficiency of the system operation.
[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
