Description

Technical Field

[0001] The utility model relates to the technical field of building energy conservation, in particular to a solar photovoltaic-thermal integrated energy-saving wall body. Background Technique

[0002] At present, solar resources have once become the focus of attention of various countries due to their unique advantages. However, most buildings collect and utilize solar energy in the roof area. The photovoltaic area is limited and the waste heat cannot be reasonably utilized, resulting in a relatively low comprehensive utilization ratio of solar resources. Although there are also a few solutions that consider combining with the building facade area to achieve energy conservation and emission reduction, there are still certain limitations. Chinese Patent CN 112082274 A discloses a composite Trombe wall body with effective heat loss reduction. This solution needs to be applied in areas with sufficient soil heat sources or water sources, and can make full use of solar resources to reduce building energy consumption. However, due to the limitations of conditions, it greatly hinders the organic combination with buildings and reduces the efficiency of the system.

[0003] Therefore, in order to improve the comprehensive utilization rate of solar resources in buildings and achieve the high-efficiency utilization of solar photovoltaic-thermal integration, the utility model proposes a modular integrated energy-saving wall body. Content of the Utility Model

[0008] A number of gravity heat pipes are embedded inside the building wall 200. The gravity heat pipe is a Z-shaped structure composed of an evaporation section 410, an adiabatic section 420, and a condensation section 430. Both the evaporation section 410 and the condensation section 430 are arranged in the vertical direction, and the condensation section 430 is entirely located above the evaporation section 410.

[0011] As a preferred technical solution of the present invention, a plurality of cold flow pipes 140 are provided inside the bracket 130, and each cold flow pipe 140 is vertically distributed between adjacent two columns of hyperbolic square glasses 110.

[0012] As a preferred technical solution of the present invention, the cold flow pipe 140 is provided with a fin structure; the remaining space in the bracket 130 is filled with a heat insulation material 150 to form a heat insulation layer.

[0013] As a preferred technical solution of the present invention, the central position of the evaporation section 410 of the gravity heat pipe is directly opposite to the central position of the hyperbolic square glass 110.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] 1) According to the refraction law, the present utility model can achieve the focusing of light at the evaporation section of the gravity heat pipe, reduce the light and heat loss, and improve the light and heat utilization efficiency. The present utility model is provided with a hyperbolic square glass and a flexible transparent solar panel. According to the refraction law, the light undergoes different degrees of refraction after passing through the two. Since the center of the evaporation section of the gravity heat pipe is directly opposite to the center positions of the two, the light is focused here. At the same time, the outer surface of the evaporation section of the gravity heat pipe is coated with an electroplated coating, which can fully absorb solar energy.

[0022] 2) The present utility model selects cold water flow to cool the flexible transparent solar panel, avoiding the loss caused by too high temperature, and at the same time, domestic hot water can be obtained, improving the resource utilization efficiency of the system. The bottom of the cold flow pipe in the present utility model can be set as the water inlet, and the top can be set as the water outlet, so as to introduce cold flow for cooling and lead out the warm flow for recycling. At the same time, the fin structure can improve the heat exchange efficiency.

[0023] 3) The present utility model can achieve multiple power generations, supply indoor loads or be incorporated into the power grid, effectively alleviating the problem of too high building energy consumption. The flexible transparent solar panel in the present utility model can achieve photovoltaic power generation, and the turbine power generation device can utilize the working medium in the gravity heat pipe to realize passive rotation for multiple power generations. The electric energy generated by the two can not only be used to supply indoor loads, but also be incorporated into the power grid for use.

[0024] 4) The present utility model selects two forms of heat radiation and heat convection, which can effectively improve the heat exchange efficiency. The heat of the condensation section of the gravity heat pipe in the present utility model is transferred to the heat storage bricks. Since the inner side adiabatic layer and the internal plaster layer can isolate the heat transfer, the heat storage bricks can only transfer heat to the air between the encapsulated wall and the building wall in the form of heat radiation. The hot air rises through the first air outlet, and the indoor cold air sinks through the second air outlet, thus forming heat convection to increase the indoor temperature.

[0025] 5) The utility model can actively realize the indoor temperature control function and improve the service life of the building. The utility model is provided with a temperature sensing device inside the house, and the temperature sensing device is connected to the central control system to directly control the electric control valve. The central control system makes decisions based on the temperature feedback by the temperature sensing device, controls the valve opening degree so as to actively regulate the room temperature.

[0033] As Figure 1-2 shown, the embodiment of the present utility model provides a solar photovoltaic and solar thermal integrated energy-saving wall, including a photovoltaic curtain wall, a building wall 200 and a packaged wall; wherein, the photovoltaic curtain wall is stably installed on the outer side of the building wall 200, and there is a gap between the inner side of the building wall 200 and the packaged wall.

[0034] AsFigure 1 , Figure 3 and Figure 4 As shown, the photovoltaic curtain wall includes a bracket 130, a hyperbolic square glass 110 and a flexible transparent solar panel 120; wherein, the bracket 130 is provided with a plurality of square through holes distributed in a matrix manner, and a plurality of hyperbolic square glasses 110 are respectively mounted on the corresponding square through holes of the bracket 130; a flexible transparent solar panel 120 is embedded on the inner surface of each hyperbolic square glass 110, and the flexible transparent solar panel 120 is adjusted into a hyperbolic square structure with high light-concentrating ability according to the shape of the hyperbolic square glass 110, photovoltaic power generation is achieved through the flexible transparent solar panel 120, and the degree of light refraction can be adjusted to achieve focusing; a plurality of vertically distributed cold flow pipes 140 are arranged inside the bracket 130, and each cold flow pipe 140 is located between two adjacent rows of hyperbolic square glasses 110; the cold flow pipe 140 is provided with a fin structure, and the remaining space in the bracket 130 is filled with a heat-insulating material 150 to form a heat-insulating layer, and the heat in the flexible transparent solar panel 120 is absorbed by the heat-insulating material 150, so as to facilitate efficient heat exchange with the cold flow through the cold flow pipe 140.

[0035] like Figure 4 As shown, a plurality of gravity heat pipes are embedded inside the building wall 200, and the gravity heat pipe is a Z-shaped structure consisting of an evaporation section 410, an insulation section 420 and a condensation section 430, wherein the evaporation section 410 and the condensation section 430 are arranged in a vertical direction and the condensation section 430 is higher than the evaporation section 410 as a whole; the evaporation section 410 is located on the outer side of the building wall 200 and faces the hyperbolic square glass 110, the insulation section 420 runs through the interior of the building wall 200, and the condensation section 430 is embedded in the interior of the encapsulation wall.

[0036] Except for the first row of hyperbolic square glasses 110 on the bracket 130, each of the remaining hyperbolic square glasses 110 corresponds to a gravity heat pipe, and the center position of the gravity heat pipe evaporation section 410 is directly opposite to the center position of the hyperbolic square glass 110, so that the light is focused there. Figure 1 and Figure 4 .

[0037] like Figure 4 As shown, the outer surface of the evaporation section 410 of the gravity heat pipe is coated with an electroplating coating 440 with excellent optical properties and high temperature resistance, and black nickel plating, black chromium plating or black cobalt plating can be selected; the electroplating coating improves the light absorption capacity and enhances the light and heat utilization efficiency.

[0038] like Figure 5 As shown, the heat-insulating section 420 of the gravity heat pipe has a built-in turbine generator 450, which uses the working medium in the gravity heat pipe to achieve secondary power generation for indoor loads or to be incorporated into the power grid.

[0039] Among them, the working medium in the gravity heat pipe can be selected from phase change heat storage materials with relatively small volume changes such as freon or dimethylamine to prevent the gravity heat pipe from being damaged due to the internal and external pressure differences.

[0040] The condensation section 430 of the gravity heat pipe is provided with a fin structure to improve the heat exchange efficiency between the gravity heat pipe and the encapsulation wall.

[0041] As Figure 1-4 shown, the encapsulation wall is built by heat storage bricks 510, and a first air inlet 520 is provided at its upper end, and a second air inlet 530 is provided at its lower end. Electric control valves are respectively provided at the first air inlet 520 and the second air inlet 530, and the valve openings can be directly regulated by a temperature sensing device arranged inside the house connecting to a central control system.

[0042] As Figure 3 and Figure 4 shown, an external plaster layer 300 is evenly laid on the outer surface of the building wall 200 and is connected to the bracket 130 of the photovoltaic curtain wall through the external plaster layer 300; an insulating layer 600 and an internal plaster layer 700 are sequentially and evenly laid on the inner side surface of the encapsulation wall, and the single-sided heat transfer of the encapsulation wall is realized through the insulating layer 600 and the internal plaster layer 700, which is convenient for forming air convection.

[0043] The working principle and usage process of the solar photovoltaic-thermal integrated energy-saving wall of the present utility model are as follows:

[0044] Incident light is incident on the surface of the hyperbolic square glass 110 of the energy-saving wall. Part of the light is absorbed by the embedded flexible transparent solar panel 120 to realize photovoltaic power generation for indoor load use or grid connection. Part of the light is refracted and converged at the evaporation section 410 of the gravity heat pipe. During this period, the heat preservation material 150 can transfer heat to the cold fluid in the cold fluid pipe 140 to avoid the temperature of the flexible transparent solar panel 120 being too high, and the heated cold fluid can be recycled;

[0045] The working medium in the gravity heat pipe absorbs sufficient heat energy and vaporizes. The gaseous working medium transfers heat from the evaporation section 410 through the adiabatic section 420 to the condensation section 430 to the heat storage bricks 510. The gaseous working medium liquefies and releases heat to form a liquid working medium. The liquid working medium returns to the evaporation section 410 through the adiabatic section 430 for cyclic operation. During this period, the working medium can drive the turbine power generation device 450 to rotate and generate electricity;

[0046] Since the inner side insulation layer 600 of the encapsulated wall and the inner plaster layer 700 isolate heat transfer, heat can only be transferred to the air between the encapsulated wall and the building wall 200 in the form of thermal radiation. The hot air in the gap rises and enters the room through the first air vent 520, and the cold air in the room sinks and enters the gap through the second air vent 530, thereby forming a heat convection cycle. During this period, the indoor temperature sensor device detects the indoor temperature in real time. The central control system connected to the temperature sensor device can directly control the opening of the electric control valves of the first air vent and the second air vent to achieve indoor temperature regulation.

[0047] The utility model can realize photovoltaic power generation by stably installing the photovoltaic curtain wall on the building wall, and at the same time improve the efficiency of light and heat utilization. It can not only heat the cold flow for recycling, but also transmit it to the packaging wall through the gravity heat pipe in the building wall to heat the indoor air. During this period, the working medium in the gravity heat pipe can drive the turbine generator to realize secondary power generation, which is supplied to the indoor load or connected to the power grid; a gap is left between the building wall and the packaging wall, and a first air outlet and a second air outlet are opened at the same time, so that the indoor air can be heated by heat radiation and heat convection at the same time, thereby improving the heat exchange efficiency.

[0048] The above are only preferred embodiments of the present invention. It should be noted that the scope of the present invention is determined by the scope of the appended claims. However, the present invention is not limited to the above embodiments. For those skilled in the art, various adjustments, combinations and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention is described in detail through the above embodiments, the present invention is not limited to the above embodiments. For those skilled in the art, several modifications and improvements can be made while being in line with the concept of the present invention, covering more embodiments, which should also be regarded as the scope of protection of the present invention.
