Description

Technical Field

[0001] This invention relates to the field of building energy conservation technology, specifically to a photovoltaic louvered energy-saving window. Background Technology

[0002] Windows are a crucial component of building envelopes and also a weak point in thermal insulation. Energy loss through windows can account for up to 50% of the building envelope's energy consumption. While single-window energy-saving technologies can reduce indoor air conditioning load to some extent, further improvements in energy efficiency are extremely difficult due to their inherent limitations. Therefore, multi-functional integrated energy-saving windows using next-generation energy-saving glass technologies are needed, such as photovoltaic heat-insulating windows, photovoltaic photochromic windows, and photovoltaic louvered energy-saving windows. However, achieving multi-functionality in energy-saving windows inevitably increases the structural complexity of the glass, and how to organically combine various functions and modules to achieve high-efficiency energy saving remains a challenge to overcome.

[0003] An existing patent describes a photovoltaic louvered semiconductor temperature-controlled energy-saving window (publication number CN204738716U). This window utilizes photovoltaic louvers to convert solar radiation into direct current to drive a thermoelectric heat pump chip assembly for cooling or heating, blocking outdoor solar radiation and reducing heat transfer between the window and outdoor air, thus lowering indoor air conditioning energy consumption. However, this type of energy-saving window lacks ventilation, failing to meet the oxygen needs of indoor occupants, or requiring an additional ventilation system to meet indoor air quality requirements. Furthermore, heat tends to accumulate near the photovoltaic louvers in this structure, and excessively high temperatures can reduce the efficiency of the photovoltaic power generation chip and the semiconductor heat pump chip. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A photovoltaic louvered energy-saving window includes a window body, which is zigzag-shaped and has an internal partition to divide the interior space into two air-conditioning chambers. Both ends of the two air-conditioning chambers are connected to the indoor and outdoor environments to form two airflow channels. The airflow channel closer to the indoor environment is a fresh air channel, which contains a temperature control unit and a first fan unit. The airflow channel closer to the outdoor environment is an exhaust gas channel, which has a photovoltaic louvered blind assembly vertically positioned at a location corresponding to the outdoor environment. A second fan unit is located at any position inside the exhaust gas channel. The top of the window body has an electrical control component that is electrically connected to the temperature control unit, the first fan unit, the photovoltaic louvered blind assembly, and the second fan unit.

[0007] Preferably, the two ends of the fresh air duct are a fresh air inlet and a fresh air outlet, respectively, and the two ends of the exhaust gas duct are an exhaust gas inlet and an exhaust gas outlet. The fresh air inlet is positioned higher than the exhaust gas outlet, and both are located on the bottom sides of the window body and connected to the outdoor environment. The fresh air outlet is positioned lower than the exhaust gas inlet, and both are located on the top sides of the window body and connected to the indoor environment. The fresh air inlet and the exhaust gas inlet are located on the same side of the window body, and the fresh air outlet and the exhaust gas outlet are located on the same side of the window body.

[0009] Preferably, the fresh air duct is provided with a first fan unit at a position between the semiconductor temperature control and the fresh air outlet. The first fan unit includes a plurality of first fans, which are arranged in a uniform array along the width direction of the window body within the fresh air duct.

[0011] Preferably, the exhaust gas passage is provided with a second fan unit near the exhaust gas inlet. The second fan unit includes multiple second fans, which are arranged in a uniform array along the width direction of the window body within the exhaust gas passage.

[0012] Preferably, the photovoltaic venetian blind assembly includes a servo motor, venetian blinds, and a photovoltaic cell string.

[0029] The technical solution of the present invention will now be clearly and completely described through specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] See Figures 1-3 As shown, a photovoltaic louvered energy-saving window is installed on a wall and replaces the original ordinary window. This energy-saving window includes a window body 1 with a zigzag shape. The top and bottom of the window body 1 are respectively embedded in the wall, and the middle position is used to isolate the indoor environment from the outdoor environment. That is, in terms of material selection, at least the middle position of the window body 1 is made of glass.

[0031] To enable this energy-saving window to "breathe," i.e., to exchange air between indoors and outdoors, a partition 2 is provided inside the window body 1 to divide its internal space into two air-conditioning chambers. The two ends of the two air-conditioning chambers are connected to the indoor and outdoor environments to form two airflow channels. The airflow channel located closer to the indoor environment is the fresh air channel 3, and the airflow channel located closer to the outdoor environment is the exhaust gas channel 4. A first fan unit 5 and a second fan unit 6 are respectively installed in the fresh air channel 3 and the exhaust gas channel 4. An electronic control assembly consisting of a battery 7 and a microcontroller 8 is provided at the top of the window body 1 to control the first fan unit 5 and the second fan unit 6.

[0032] The first fan unit 5 includes multiple first fans 501, which are arranged in a uniform array along the width of the window body 1 within the fresh air duct 3. The second fan unit 6 includes multiple second fans (not shown in the figure), which are arranged in a uniform array along the width of the window body 1 within the exhaust gas duct 4. The multiple first fans 501 in the first fan unit 5 draw in fresh air from the outdoor environment and deliver it to the indoor environment through the fresh air duct 3. The multiple second fans in the second fan unit 6 draw in stale exhaust gas from the indoor environment and discharge it to the outdoor environment through the exhaust gas duct 4, thereby achieving indoor-outdoor ventilation and effectively reducing the accumulation of harmful gases indoors, preventing positive pressure from forming indoors due to poor ventilation in a closed space. Simultaneously, corresponding through-holes are provided on the wall where the energy-saving window is installed to connect with the fresh air duct 3 and the exhaust gas duct 4. Air grilles or other components can be covered at these through-holes to improve aesthetics.

[0033] Specifically, the two ends of the fresh air duct 3 are a fresh air inlet 301 and a fresh air outlet 302, respectively, and the two ends of the exhaust gas duct 4 are an exhaust gas inlet 401 and an exhaust gas outlet 402. The fresh air inlet 301 is positioned higher than the exhaust gas outlet 402, and both are located on the bottom sides of the window body 1 and connected to the outdoor environment. By positioning them on opposite sides, exhaust gas discharged through the exhaust gas outlet 402 is prevented from being drawn back into the fresh air inlet 301. The fresh air outlet 302 is positioned lower than the exhaust gas inlet 401, and both are located on the top sides of the window body 1 and connected to the indoor environment. By positioning them on opposite sides, fresh air discharged through the fresh air outlet 302 is prevented from being drawn out through the exhaust gas inlet 401 before entering the indoor environment. The first fan unit 5 is preferably installed near the fresh air inlet 301, and the second fan unit 6 is preferably installed near the exhaust gas inlet 401 to improve the extraction effect.

[0034] Meanwhile, the fresh air inlet 301 and the exhaust gas inlet 401 are located on the same side of the window body 1, and the fresh air outlet 302 and the exhaust gas outlet 402 are located on the same side of the window body 1. That is, the fresh air inlet 301 and the fresh air outlet 302, and the exhaust gas inlet 401 and the exhaust gas outlet 402 are arranged in a cross manner relative to the window body 1, so as to increase the air path length of the airflow in the fresh air channel 3 and the exhaust gas channel 4, thereby slowing down the airflow speed at the fresh air outlet 302 and the exhaust gas outlet 402.

[0035] In addition, a temperature control device is provided in the fresh air duct 3 to enable the energy-saving window to have a temperature control function, which works in conjunction with the indoor air conditioner to reduce the indoor air conditioning load. Preferably, the temperature control device is set in the partition plate 2 near the fresh air inlet 301. In this embodiment, the temperature control device is a semiconductor temperature control device 9, which has a control terminal 901 and a function terminal 902, with the function terminal 902 placed in the fresh air duct 3 and the control terminal 901 placed in the exhaust gas duct 4. In conjunction with the semiconductor temperature control unit 9, the aforementioned first fan unit 5 is positioned within the fresh air duct 3 between the semiconductor temperature control unit 9 and the fresh air outlet 302. A first air pressure sensor 10 and a first temperature sensor 11 are sequentially installed on the inner wall of the fresh air duct 3 between the fresh air inlet 301 and the semiconductor temperature control unit 9, along the air inlet direction. A second air pressure sensor 12 and a second temperature sensor 13 are sequentially installed on the inner wall of the fresh air outlet 302, along the air inlet direction. The first air pressure sensor 10, the first temperature sensor 11, the second air pressure sensor 12, and the second temperature sensor 13 are all electrically connected to the electronic control component.

[0036] The fresh air duct 3 and the exhaust gas duct 4 are designed separately, which greatly reduces the thermal interference of heat conduction on the temperature control unit. In summer, the microcontroller 8 receives feedback from the first wind pressure sensor 10 and the first temperature sensor 11 located at the fresh air inlet 301, and the second wind pressure sensor 12 and the second temperature sensor 13 located at the fresh air outlet 302. It controls the first fan unit 5 to adjust the wind speed in the fresh air duct 3 so that a sufficient amount of air is drawn into the fresh air duct 3. The semiconductor temperature control unit 9 absorbs heat and cools the air to a corresponding degree in the fresh air duct 3. The cooled air enters the indoor environment through the fresh air outlet 302, working together with the indoor air conditioner to reduce the load on the indoor air conditioner. In winter, the semiconductor temperature control unit 9 generates heat to a corresponding degree in the fresh air duct 3. The heated air enters the indoor environment through the fresh air outlet 302. Correspondingly, during the process of indoor polluted exhaust gas being drawn into the exhaust gas channel 4 from the exhaust gas inlet 401 by the second fan unit 6 and discharged to the outside from the exhaust gas outlet 402, the polluted exhaust gas can cool or heat the control terminal 901 of the semiconductor temperature control 9 in the exhaust gas channel 4. At the same time, it can also control the second fan unit 6 to adjust the air intake in the exhaust gas channel 4, so as to achieve the effect of controlling the temperature of the semiconductor temperature control 9.

[0037] Furthermore, a photovoltaic venetian blind assembly is vertically installed at the location corresponding to the outdoor environment in the exhaust gas duct 4, enabling this energy-saving window to have dimming and self-generating functions. The photovoltaic venetian blind assembly includes a servo motor 14, venetian blinds, and photovoltaic cell strings. The venetian blinds include multiple louvers, and each louver surface is attached with a photovoltaic cell string to form a photovoltaic venetian blind unit 15. Multiple photovoltaic venetian blind units 15 are connected in series or parallel with each other through wires and are electrically connected to the storage battery 7 in the electronic control component. By converting sunlight into electrical energy, it provides power to various functional components in the energy-saving window, and can store excess electrical energy in the storage battery 7, ensuring that this energy-saving window can operate normally even in cloudy or rainy weather. The servo motor 14 is installed in the exhaust gas duct 4 through a fixing rod 16 and is connected to the venetian blinds through a traction rope (not shown in the figure) to control the raising and lowering of the venetian blinds and the rotation of multiple photovoltaic venetian blind units 15. A light sensor 17 is installed on the inner wall of the fresh air duct 3 near the indoor environment at the location corresponding to the venetian blinds. The light sensor 17 is electrically connected to the electronic control component. While meeting indoor lighting needs, the rotation angle of multiple photovoltaic louver units 15 can be automatically adjusted according to changes in the angle of solar incidence to achieve a balance between shading effect and power generation efficiency. For example, when the user selects the power generation priority mode, the microcontroller 8 controls the servo motor 14 to adjust the angle of multiple photovoltaic louver units 15 to be perpendicular to the angle of solar incidence, and automatically adjusts their rotation angle according to changes in the angle of solar incidence to always maintain a perpendicular state. When the user selects the light priority mode, the microcontroller 8 receives real-time data from the light sensor 17 and continuously adjusts the rotation angle of multiple photovoltaic louver units 15 by controlling the servo motor 14 to prioritize meeting the user's lighting requirements. The electrical energy converted by the multiple photovoltaic louver units 15 is stored in the battery 7.

[0038] The middle section of the window body 1, corresponding to the two sides of the window body 1 facing the outdoor and indoor environments, and the section corresponding to the venetian blinds on the partition plate 2, are respectively equipped with an outer glass layer 101, an inner glass layer 102, and a laminated glass layer 201. This triple-glazed configuration significantly improves thermal insulation, sealing, sound insulation, and heat insulation performance compared to a double-glazed configuration. Placing the photovoltaic venetian blind assembly between the outer glass layer 101 and the laminated glass layer 201, within the exhaust gas channel 4, reduces the risk of damage to the individual photovoltaic venetian blinds 15 from external influences and allows the heat from the photovoltaic cell strings on multiple photovoltaic venetian blinds 15 to be discharged with the exhaust gas, preventing temperature increases from affecting the photovoltaic cell strings and improving photoelectric conversion efficiency. Therefore, the exhaust gas in the exhaust gas channel 4 can cool the multiple photovoltaic louver units 15 and the semiconductor temperature control unit 9 in the photovoltaic louver curtain assembly in sequence during its discharge to the outside. The ventilation volume in the exhaust gas channel 4 is adjusted by the second fan unit 6, thereby controlling the temperature of the photovoltaic cell string and the semiconductor temperature control unit 9 in the photovoltaic louver unit 15, so that the two operate at the optimal temperature state point, thereby improving energy utilization and energy saving efficiency.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
