Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The core of the present invention is to provide a solar building that can utilize solar energy to improve the indoor temperature, reduce the building's cooling and heating energy consumption, and increase the utilization rate of renewable energy.

[0031] It should be noted that in this embodiment, the orientation or positional relationship indicated by "up", "down", "front", "back", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0032] Please refer to Figure 1 , the present application provides a solar building, including a building body 1, a photoelectric and solar thermal integrated system, and a thermoelectric cooling system.

[0033] An air flow channel 11 is provided in the wall of the building body 1, and both the intake end 111 and the outlet end 112 of the air flow channel 11 are communicated with the interior of the building body 1.

[0034] The photoelectric and solar thermal integrated system includes a photoelectric and solar thermal integrated device 3 and an air duct assembly 4. The photoelectric and solar thermal integrated device 3 is used to receive solar radiation and convert it into electric energy and heat energy. The air inlet end of the air duct assembly 4 is arranged close to the photoelectric and solar thermal integrated device 3, and the air outlet end passes through the wall and is connected to the air flow channel 11 arranged in the wall, and is used to drive the outdoor air to flow through the photoelectric and solar thermal integrated device 3 to absorb heat and increase the temperature, and then flow into the air flow channel 11.

[0035] The semiconductor refrigeration system includes a semiconductor refrigeration chip 5 and a control circuit. The semiconductor refrigeration chip 5 is penetrated through the wall, and its first end extends into the air flow channel 11, and the second end of the semiconductor refrigeration chip 5 extends outside the air flow channel 11. The photo-thermal-electric integrated device 3 is electrically connected to the semiconductor refrigeration chip 5 through the control circuit, and the control circuit is used to adjust the direction of the current flowing through the semiconductor refrigeration chip 5, so as to switch either end of the semiconductor refrigeration chip 5 from the refrigerating end to the heating end, and the other end from the heating end to the refrigerating end.

[0036] It should be noted that the photo-thermal-electric integrated device 3 is a device with power generation and heat supply functions, which is manufactured by combining a solar cell and a solar collector using solar photo-electric / photo-thermal comprehensive utilization technology. In this application, the photo-thermal-electric integrated device 3 is used as an energy supply component of the building to provide electricity and heat. Among them, the heat exchanges with the outdoor air through convection, and the outdoor air is heated to hot air, and can flow into the room through the air duct assembly 4 and the air flow channel 11 in sequence to achieve the purpose of heating the room; the electricity is used to drive the operation of the semiconductor refrigeration chip. The semiconductor refrigeration chip can switch the cold end and the hot end by changing the polarity of the direct current, that is, the current direction, so as to realize the refrigeration or heating function. The switching of the cold and hot ends of the semiconductor needs to be realized by the control circuit. As Figure 3 shown, the control circuit consists of a main wire and a three-phase switch 6. The wire is connected between the semiconductor refrigeration chip 5 and the photo-thermal-electric integrated device 3 to form a circuit. The three-phase switch 6 is arranged on the main wire. In this way, the direction of the current in the wire is adjusted by turning the control knob of the three-phase switch 6. Specifically, in summer, the control circuit is energized in the forward direction, the first end of the semiconductor refrigeration chip 5 is the refrigerating end, and the second end is the heating end. In winter, the control circuit is energized in the reverse direction, the first end of the semiconductor refrigeration chip 5 is the heating end, and the second end is the refrigerating end, so as to realize the switching of the cold and hot ends of the semiconductor refrigeration chip 5 during the season change. In addition, the control circuit commutation with the above structure can avoid problems such as the air flow channel 11 not being airtight and the semiconductor refrigeration chip 5 being easily worn caused by switching the physical direction of the semiconductor.

[0037] For the solar building configured with the above structure, when in use in summer, the electric energy generated by the photoelectric-thermal integrated device 3 flows through the control circuit to the semiconductor refrigeration sheet 5, and the control circuit controls forward power-on. At this time, the first end of the semiconductor refrigeration sheet 5 located indoors is the refrigeration end, and the second end of the semiconductor refrigeration sheet 5 located outdoors is the heating end. Indoor air enters through the air inlet 111 of the air flow channel 11, flows through the first end of the semiconductor refrigeration sheet 5 and is cooled into cold air, and finally flows into the room through the air outlet 112 of the air flow channel 11, thereby achieving indoor cooling. When in use in winter, the control circuit controls reverse power-on, that is, reverses the current direction of the semiconductor refrigeration sheet 5, so that the first end of the semiconductor refrigeration sheet 5 is switched from the refrigeration end to the heating end, and the second end is switched from the heating end to the refrigeration end. Indoor air enters through the air inlet 111 of the air flow channel 11, flows through the first end of the semiconductor refrigeration sheet 5 and is heated into hot air, and finally flows into the room through the air outlet 112 of the air flow channel 11. At the same time, the air duct assembly 4 drives outdoor air to flow through the photoelectric-thermal integrated device 3 to absorb heat and warm up and then flow into the air flow channel 11, and finally flows into the room through the air outlet 112 of the air flow channel 11, thereby achieving indoor heating.

[0038] In summary, the photoelectric-thermal integrated device 3 of the present application serves as an energy supply component of the building. In summer, it converts photovoltaic energy into electric energy, and uses semiconductors to convert the electric energy into cold energy to reduce the building's summer cooling energy consumption. At the same time, photovoltaic direct drive reduces the loss of photoelectric storage. In winter, it converts photovoltaic energy into electric energy, uses semiconductors to convert the electric energy into heat, and at the same time conveys the waste heat of photoelectric conversion to the room through the air duct assembly 4, reducing the low energy consumption or even zero energy consumption of the building's winter heating. Therefore, the present application can utilize solar energy to improve the indoor temperature, reduce the building's cooling and heating energy consumption, and improve the utilization rate of renewable energy.

[0039] Considering the specific structure of the air duct assembly 4, on the basis of the above embodiment, please refer to Figure 1 , the air duct assembly 4 includes an air duct body 41, a control valve 42 and a first fan 43. The first fan 43 is arranged between the heat absorption end of the photoelectric-thermal integrated device 3 and the air inlet end of the air duct body 41. The air outlet end of the air duct body 41 is communicated with the air flow channel 11. The control valve 42 is arranged on the air duct body 41 and is used to control the on-off of the air duct body 41, and the control valve 42 is only opened in winter.

[0040] It can be understood that the photoelectric and photothermal integrated device 3 is usually an absorber plate. After the absorber plate absorbs solar radiant energy, its temperature rises to generate heat. After the outdoor air exchanges convective heat with the absorber plate, its temperature rises. The first fan 43 is arranged at the air inlet end of the air duct body 41 and adjacent to the absorber plate, which can blow the heated outdoor air into the air duct body 41. This not only increases the air supply volume of the indoor warm air to enhance the indoor heating effect, but also dissipates heat from the photoelectric and photothermal integrated device 3 in the form of air cooling, so that the temperature of the photoelectric and photothermal integrated device 3 drops, which is beneficial to improving the power generation efficiency of the photoelectric and photothermal integrated device 3. It should be noted that the photoelectric and photothermal integrated power generation efficiency is high, and the photovoltaic power generation increases, which can increase the cold or heat quantity introduced into the room by the semiconductor refrigerating sheet 5, thereby enhancing the indoor cooling or heating effect, and further greatly reducing the refrigeration and heating energy consumption of the building in winter and summer.

[0041] To achieve the adaptive regulation of the power supply of the photoelectric and photothermal integrated device 3, on the basis of the above embodiment, please refer to Figure 1 , the photoelectric and photothermal integrated device 3 is electrically connected to the first fan 43.

[0042] It can be understood that the fan speed is related to its power supply. The more the power supply, the higher the fan power and the faster the speed. Thus, the electric energy generated by the photoelectric and photothermal integrated device 3 is used to drive the first fan 43 to operate. The more electric energy generated by the photoelectric and photothermal integrated device 3, the higher the speed of the first fan 43, which enhances the heat dissipation effect of the photoelectric and photothermal integrated device 3, is beneficial to further increasing the electric energy generated by the photoelectric and photothermal integrated device 3, thereby realizing the adaptive regulation of the power supply of the photoelectric and photothermal integrated device 3, maximizing the conversion of photovoltaic into electric energy, and effectively improving the solar energy utilization rate.

[0043] Considering the direction and flow rate of the indoor air entering and leaving the air flow channel 11, on the basis of the above embodiment, please refer to Figure 2 , a second fan 12 and a third fan 13 are arranged in the air flow channel 11. The second fan 12 is arranged near the first end of the semiconductor refrigerating sheet 5, and the third fan 13 is located between the air outlet end of the air duct assembly 4 and the air outlet end 112 of the air flow channel 11.

[0044] It can be understood that when the fan rotates, the fan blades will generate negative pressure to suck in a large amount of surrounding air, and then the fan blades will push the air forward to form an air flow. Thus, the second fan 12 will suck in indoor air through the air inlet end 111 of the air flow channel 11 and push the indoor air forward, and the third fan 13 will push the indoor air forward to flow into the room through the air outlet end 112 of the air flow channel 11. On the one hand, the second fan 12 and the third fan 13 can play a role in pushing the indoor air to flow from the air inlet end 111 to the air outlet end 112 of the air flow channel 11 to determine the flow direction of the indoor air; on the other hand, the indoor air flow rate in the air flow channel 11 can also be increased to ensure that the indoor air fully exchanges heat with the first end of the semiconductor refrigeration sheet 5, that is, to increase the indoor cooling capacity in summer and increase the indoor heat in winter, thereby enhancing the effect of improving the indoor temperature.

[0045] In addition, in winter, the third fan 13 can fully mix the indoor air heated after passing through the first end of the semiconductor refrigeration sheet 5 and the hot outdoor air introduced through the air duct body 41, so that the heat is more evenly distributed in the mixed air, thereby improving the heat supply effect to the room.

[0046] To achieve automatic control of the indoor temperature with solar radiation, on the basis of the above embodiments, please refer to Figure 3 , the second fan 12 is electrically connected to the photovoltaic-thermal integrated device 3, and / or, the third fan 13 is also electrically connected to the photovoltaic-thermal integrated device 3. Among them, the second fan 12 and the third fan 13 can both be connected in parallel to the main wire through branch wires. After the current of the photovoltaic-thermal integrated device 3 passes through the second fan 12 or the third fan 13, it then passes through the semiconductor refrigeration sheet 5 and returns to the photovoltaic-thermal integrated device 3.

[0047] It can be understood that the rotation speeds of the second fan 12 and the third fan 13 are both related to the power supply. The more power is supplied, the greater the rotation speed. Therefore, in summer, the photovoltaic-thermal integrated device 3 supplies power to the semiconductor refrigeration sheet 5, the second fan 12, and the third fan 13. The first end of the semiconductor refrigeration sheet 5 located indoors is the cold end. As the outdoor solar radiation increases, the more power the photovoltaic-thermal integrated device 3 supplies to the semiconductor refrigeration sheet 5, the second fan 12, and the third fan 13. The temperature of the cold end of the semiconductor refrigeration sheet 5 decreases, and the rotation speeds of the second fan 12 and the third fan 13 increase, resulting in an increase in the indoor air flow rate in the air flow channel 11. Moreover, the heat exchange effect between the indoor air and the cold end of the semiconductor refrigeration sheet 5 is stronger, so that the indoor air supply volume increases and the supply air temperature is lower, thereby meeting the automatic control of the indoor cooling capacity varying with solar radiation. In winter, the photovoltaic-thermal integrated device 3 supplies power to the semiconductor refrigeration sheet 5, the second fan 12, and the third fan 13. At this time, the control valve 42 is opened, that is, the air duct assembly 4 for transporting heat is turned on. The first end of the semiconductor refrigeration sheet 5 located indoors is the hot end. As the outdoor solar radiation increases, the more heat energy the photovoltaic-thermal integrated device 3 generates, and the more heat is generated by the power generation of the photovoltaic-thermal integrated device 3. The temperature of the outdoor air is higher after heat exchange with the photovoltaic-thermal integrated device 3, and the power supply to the third fan 13 by the photovoltaic-thermal integrated device 3 increases, and the rotation speed of the third fan 13 increases, so that the indoor air supply volume increases and the supply air temperature is higher. At the same time, the more power the photovoltaic-thermal integrated device 3 supplies to the semiconductor refrigeration sheet 5 and the second fan 12, the higher the temperature of the hot end of the semiconductor refrigeration sheet 5, and the rotation speed of the second fan 12 increases, further increasing the indoor air supply volume and raising the supply air temperature, thereby meeting the automatic control of the indoor heat supply varying with solar radiation.

[0048] Taking the application of this application to civil buildings in temperate regions as an example for detailed description, during the operation in summer in the Northern Hemisphere, at the initial stage of work, such as from 7 am to 10 am, the solar radiation intensity is low, the photovoltaic power generation is less, and the cooling capacity of the semiconductor refrigeration sheet 5 is small. At this time, the indoor temperature is low and the required cooling capacity is small, and the supply and demand are adapted; during the mid-stage of work, such as from 10 am to 2 pm, the solar radiation intensity is high, the photovoltaic power generation is more, and the cooling capacity of the semiconductor refrigeration sheet 5 is large. At this time, the indoor temperature is high and the required cooling capacity is large, and the supply and demand are adapted; during the later stage of work, such as from 2 pm to 6 pm, the solar radiation intensity is low, the photovoltaic power generation is less, and the cooling capacity of the semiconductor refrigeration sheet 5 is small. At this time, the indoor temperature is low and the required cooling capacity is small, and the supply and demand are adapted; during the shutdown time, such as from 6 pm to 7 am the next day, equipment rest and maintenance are carried out. Therefore, in summer, this application uses variable frequency technology and semiconductor refrigeration technology to adaptively adjust the required indoor cooling capacity according to the change of solar radiation intensity, that is, to make the indoor cooling load have a positive relationship with the solar radiation intensity, so as to realize the adaptive regulation of the indoor temperature according to the outdoor temperature, not only reducing the building's summer cooling energy consumption, but also improving the user's comfort.

[0049] During the operation in the Northern Hemisphere winter, within the working hours, such as from 8:00 a.m. to 5:00 p.m., the electricity generated by the photovoltaic-thermal integrated device 3 is transmitted through the circuit to the semiconductor refrigeration chip 5, the second fan 12 and the third fan 13. The hot end of the semiconductor refrigeration chip 5 generates heat. The second fan 12 operates to suck indoor air through the intake end 111 of the air duct 11. The indoor air exchanges heat with the hot end of the semiconductor refrigeration chip 5 and warms up. At the same time, the outdoor air that absorbs the heat of the photovoltaic-thermal integrated device 3 also enters the room through the air duct 11. The third fan 13 operates to mix the warmed indoor air and outdoor air and flow them into the room through the outlet end 112 of the air duct 11, and the indoor temperature rises. During the shutdown time, such as from 5:00 p.m. to 8:00 a.m. the next day, the photovoltaic part stops operating, and the photovoltaic-thermal integrated device 3 stores heat and continues to assist other heating equipment in the room for heating, meeting the heat demand in the room.

[0050] Optionally, please refer to Figure 1 , a fourth fan 7 for dissipating heat from the semiconductor refrigeration chip 5 is provided at the second end of the semiconductor refrigeration chip 5. The fourth fan 7 is installed on the outdoor wall to dissipate heat from the semiconductor refrigeration chip 5, so that the second end of the semiconductor refrigeration chip 5 operates at a normal temperature.

[0051] Furthermore, please refer to Figure 3 , the fan resistance component 8 is electrically connected to the photovoltaic-thermal integrated device 3. Specifically, the fan resistance component 8 is connected to the main wire through a wire and is arranged in parallel with the semiconductor refrigeration chip 5. And the fan resistance component 8 includes the fourth fan 7 and a shunt resistor. The photovoltaic-thermal integrated device 3 supplies power to the fourth fan 7 and automatically regulates the rotation speed of the fourth fan 7 according to the solar radiation intensity, and a shunt resistor of an appropriate size is connected in parallel for shunting, which can prevent the photovoltaic power generation current from exceeding the rated current of the semiconductor refrigeration chip 5 and causing damage to the semiconductor refrigeration chip 5.

[0052] Preferably, the above-mentioned first fan 43, second fan 12, third fan 13 and fourth fan 7 are all variable-frequency fans, which can adjust the motor speed by changing the power supply frequency, thereby realizing the adjustment of the air volume, that is, realizing the adjustment of the power supply to achieve the purpose of energy saving and temperature control.

[0053] Considering the specific structure and installation position of the air duct 11, on the basis of the above-mentioned embodiment, please refer to Figure 1 , the air duct 11 includes a first pipe section and a second pipe section both in an L shape, which are respectively located in the top layers of the adjacent two side walls of the building body 1, and the head end of the first pipe section extends into the room and the tail end is connected to the head end of the second pipe section, and the tail end of the second pipe section extends into the room.

[0054] Specifically, as Figure 2As shown in the figure, the vertical part of the L-shaped first pipe section extends a certain distance along the width direction of the left wall, and the horizontal part is arranged perpendicular to the width direction of the left wall and extends into the room. The horizontal part of the L-shaped second pipe section extends a certain distance along the length direction of the rear wall, and the vertical part is arranged perpendicular to the length direction of the rear wall and extends into the room. Among them, a semiconductor refrigeration sheet 5 and a second fan 12 are arranged in the vertical part of the first pipe section, and the horizontal part of the second pipe section is communicated with the air duct body 41 and a third fan 13 is arranged. The air flow channel 11 arranged with the above structure extends from the side wall of the building to the top wall, has a long length, and can provide sufficient heat exchange space for the indoor air and the semiconductor refrigeration sheet 5 to ensure sufficient cooling or heating capacity is provided to the room. And in winter, it can provide sufficient mixing space for the indoor air heated by the semiconductor refrigeration sheet 5 and the outdoor air heated by the photoelectric and photothermal integrated device 3 to ensure sufficient heat is provided to the room. In addition, the air flow channel 11 is located at the top layer of the wall, and heat and cold are diffused from the top wall to the room, creating an environment for users as if they are in nature, avoiding heat and cold from directly blowing on users, which is beneficial to improving user comfort.

[0055] Considering the installation position of the photoelectric and photothermal integrated device 3, on the basis of the above embodiment, please refer to Figure 2 , the photoelectric and photothermal integrated device 3 is arranged on the bracket 2 with a triangular structure. The bracket 2 is used to be installed on the roof or wall of the building, which can make full use of the space and reduce the floor area. And the bracket 2 has a triangular structure, which can enhance the firm stability of the photoelectric and photothermal integrated device 3.

[0056] Preferably, a ventilation flow channel 14 is also arranged in the wall away from the air flow channel 11. The ventilation flow channel 14 communicates the indoor and outdoor of the building body 1 and is used for ventilation and air change to improve the indoor air quality. It should be noted that, as Figure 1 shown, the ventilation flow channel 14 is located on the right side of the building wall, and the air flow channel 11 is entirely located on the left side of the building wall to avoid interference between the air exchange process and the heat exchange process of the indoor air.
