[0039] In one embodiment, Figure 1 As shown, a solar ventilation wall 10 is provided, comprising:

[0040] Light-transmitting glass 102, a first vent 104 arranged on the side of the light-transmitting glass 102 away from the ground, a second vent 106 arranged on the side of the light-transmitting glass 102 close to the ground, a heavy wall 108, a third vent 110 arranged on the side of the heavy wall 108 away from the ground, a fourth vent 112 arranged on the side of the heavy wall 108 close to the ground, and a heat insulation board 114.

[0041] One side of the light-transmitting glass 102 contacts the outdoor environment, the heat-insulating board 114 is arranged on the side of the heavy wall 108 close to the indoor, and the light-transmitting glass 102 and the heavy wall 108 are arranged at intervals to form an external air passage, and the heavy wall 108 and the heat-insulating board 114 are arranged at intervals to form an internal air passage. The heat-insulating board 114 is used to prevent the heat penetrating the heavy wall 108 from flowing to the indoor environment.

[0042] In the first working mode, the first vent 104 and the second vent 106 are open, and the third vent 110 and the fourth vent 112 are closed, or the first vent 104, the second vent 106 and the fourth vent 112 are open, and the third vent 110 is closed.

[0043] When the first vent 104 and the second vent 106 are opened, and the third vent 110 and the fourth vent 112 are closed, sunlight (such as Figure 1When the sun (the straight line with arrows shown in the figure) shines on the light-transmitting glass 102, the air in the external air passage is heated up due to the sun exposure. Since the density of hot air is low, the hot air heated by the sun will rise and be discharged from the first vent 104. At this time, the discharge of hot air will form a negative pressure environment in the external air passage. Therefore, the cold air in the outdoor environment will flow into the external air passage from the second vent 106, thereby forming a continuous air flow cycle in the external air passage. The continuous air flow cycle in the external air passage can take away the heat on the heavy wall 108, avoid overheating of the indoor environment due to sun exposure, and thus maintain the temperature of the indoor environment within a suitable range to achieve heat insulation.

[0044] When the first vent 104, the second vent 106 and the fourth vent 112 are opened, and the third vent 110 is closed, when sunlight shines on the light-transmitting glass 102, the air in the external air passage is heated by sunlight. Since the density of hot air is low, the hot air heated by sunlight will rise and be discharged from the first vent 104. At this time, the discharge of hot air will form a negative pressure environment in the external air passage. Therefore, the cold air in the outdoor environment will flow into the external air passage from the second vent 106, and the cold air in the indoor environment will flow into the external air passage from the fourth vent 112, thereby forming a continuous air flow cycle in the external air passage. At this time, the continuous air flow cycle in the external air passage can not only take away the heat on the heavy wall 108, but also realize the ventilation of the indoor environment.

[0045] In the second working mode, the third vent 110 and the fourth vent 112 are opened, and the first vent 104 and the second vent 106 are closed.

[0046] When the third vent 110 and the fourth vent 112 are opened, and the first vent 104 and the second vent 106 are closed, when sunlight shines on the light-transmitting glass 102, the air in the external air passage is heated up due to the sunlight. Since the density of hot air is relatively low, the hot air heated by the sunlight will rise and be discharged from the third vent 110. At this time, the discharge of hot air will form a negative pressure environment in the external air passage. Therefore, the cold air in the indoor environment will flow into the external air passage from the fourth vent 112, thereby forming a continuous air flow cycle in the external air passage to promote air circulation in the indoor environment.

[0047] The first working mode and the second working mode can be selected according to the temperature conditions of the indoor environment and the outdoor environment. Specifically, when the outdoor temperature is higher than the indoor environment to a certain extent (such as in summer), the first working mode can be selected to prevent the temperature of the outdoor environment from penetrating into the indoor environment through the air flow between the outdoor environment and the external air channel to achieve heat insulation. When the outdoor temperature is lower than the indoor environment to a certain extent (such as in winter), the second working mode can be selected to allow the hot air heated by the sun to flow in the indoor environment through the air flow between the external air channel and the indoor environment to promote air circulation in the indoor environment.

[0048] It should be noted that the first vent 104 is not necessarily arranged at such a position. Figure 1 The position shown in the figure (where the light-transmitting glass 102 is close to the ceiling) is not required, but it only needs to be set at a position higher than the second vent 106. Of course, the higher the setting position of the first vent 104 (the farther away from the ground), the more thorough the air circulation in the external air passage. Correspondingly, the setting position of the third vent 110 is similar to that of the first vent 104, and will not be described in detail here.

[0049] Correspondingly, the second vent 106 is not necessarily arranged at such a position. Figure 1 The position shown in the figure (where the light-transmitting glass 102 is close to the ground) only needs to be set at a position lower than the first vent 104. Of course, the lower the setting position of the second vent 106 (the closer to the ground), the more thorough the air circulation in the external air passage. Correspondingly, the setting position of the fourth vent 112 is similar to that of the second vent 106, and will not be described in detail here.

[0050] Furthermore, a controller and a temperature detection device can be set up to determine the temperature difference between the indoor environment and the outdoor environment in real time, and the controller can determine the switching status of the first vent 104, the second vent 106, the third vent 110 and the fourth vent 112 according to the temperature difference, thereby realizing flexible switching between the first working mode and the second working mode.

[0051] Therefore, the above-mentioned solar ventilation wall 10, including light-transmitting glass 102, first vent 104, second vent 106, heavy wall 108, third vent 110, fourth vent 112 and insulation board 114, can heat the air in the external air channel formed by the light-transmitting glass 102 and the heavy wall 108 spaced apart through the irradiation of sunlight, so that in the first working mode, the cold air in the outdoor environment and the hot air in the external air channel form a circulation to take away the heat on the heavy wall 108 to achieve thermal insulation, and can also promote the circulation of the hot air in the external air channel and the air in the indoor environment to achieve ventilation of the indoor environment; in the second working mode, it can promote the circulation of the hot air in the external air channel and the air in the indoor environment to achieve ventilation and thermal insulation of the indoor environment.

[0052] In one embodiment, Figure 2 As shown, a side of the light-transmitting glass 102 close to the heavy wall 108 is coated with a photocatalytic material 116 .

[0053] When sunlight shines on the photocatalytic material 116, it will excite the photocatalytic material 116 and promote the photocatalytic reaction of the photocatalytic material 116. The photocatalytic reaction will generate active substances with strong oxidizing properties. These active substances can degrade pollutants in the air and convert oxides into carbon dioxide and water, thereby reducing the concentration of pollutants in the air. Therefore, coating the photocatalytic material 116 on the side of the light-transmitting glass 102 close to the heavy wall 108 can reduce the concentration of pollutants in the external air channel under sunlight and purify the air.

[0054] Furthermore, when the third vent 110 and / or the fourth vent 112 is opened, the purified air can be circulated into the indoor environment through air circulation, and the unpurified air in the indoor environment can be circulated into the external air channel, thereby purifying the air in the indoor environment.

[0055] In one embodiment, Figure 2 As shown, the solar ventilation wall 10 further includes: a photovoltaic panel 118, at least one ultraviolet lamp 120 and a controller ( Figure 2 not shown).

[0056] The photovoltaic panel 118 is disposed on a side of the heavy wall 108 close to the light-transmitting glass 102 .

[0057] The ultraviolet lamp 120 is arranged on the heat insulation board 114, and the irradiation range of the ultraviolet lamp 120 covers the area where the inner air channel is located. The ultraviolet lamp 120 is arranged on the heat insulation board 114 and can also isolate the heat generated by ultraviolet rays from penetrating into the indoor environment through the heat insulation board 114, thereby improving the heat insulation effect.

[0058] The controller is connected to the photovoltaic panel 118 and the ultraviolet lamp 120 respectively, and is used to control the start and stop of the ultraviolet lamp 120 .

[0059] The photovoltaic panel 118 can generate electricity under sunlight, convert light energy into electrical energy, and transmit the electrical energy to the controller and the ultraviolet lamp 120, so that the ultraviolet lamp 120 works under the control of the controller. The ultraviolet lamp 120 can purify the air in the irradiation area, thereby reducing the concentration of pollutants in the air in the inner air channel.

[0060] In one embodiment, Figure 2 As shown, the solar ventilation wall 10 further includes a pollutant sensor 122 .

[0061] The pollutant sensor 122 is disposed in the inner air passage, and the pollutant sensor 122 is used to detect the pollutant concentration of the air in the inner air passage.

[0062] The controller is connected to the pollutant sensor 122, and is also used to receive the pollutant concentration, and turn on the ultraviolet lamp 120 when the pollutant concentration is greater than a preset concentration threshold, and turn off the ultraviolet lamp 120 when the pollutant concentration is less than or equal to the preset concentration threshold. By detecting the pollutant concentration, the ultraviolet lamp 120 is controlled to start and stop, thereby saving electric energy.

[0063] The above-mentioned preset concentration threshold value can be determined according to the safe value of the pollutant concentration, so as to ensure that the pollutant concentration of the air in the inner air channel is kept below the safe value suitable for life.

[0064] In one embodiment, Figure 2 As shown, the solar ventilation wall 10 further includes: at least one fan 124 .

[0065] The fan 124 is disposed on the heat insulation board 114 .

[0066] The controller is connected to the fan 124, and the controller is also used to drive the fan 124 to work so as to connect the inner air passage and the indoor environment.

[0067] The controller can promote the air circulation between the inner air channel and the indoor environment by controlling the operation of the fan 124, so that in the presence of the ultraviolet lamp 120, the purified air in the inner air channel and the unpurified air in the indoor environment are circulated and exchanged, thereby achieving the effect of speaking the air in the indoor environment.

[0068] In one embodiment, Figure 2 As shown, the solar ventilation wall 10 further includes: a phase change heat storage device 126 .

[0069] The phase-change thermal storage device 126 is disposed between the photovoltaic panel 118 and the heavy wall 108 , and the phase-change thermal storage device 126 is connected to a controller.

[0070] The phase-change heat storage device 126 can store the heat generated by sunlight, and at the same time, to a certain extent, prevent the heat in the external air passage from diffusing to the indoor environment and the internal air passage, thereby achieving heat insulation. The phase-change heat storage device 126 can also maintain the photovoltaic panel 118 at a stable temperature by absorbing heat, thereby improving the power generation efficiency of the photovoltaic panel 118.

[0071] The phase-change heat storage device 126 is connected to the controller and can convert heat into electrical energy for use by the ultraviolet lamp 120 and the fan 124 connected to the controller, thereby improving energy utilization efficiency.

[0072] Furthermore, during periods of insufficient sunlight such as cloudy days or at night, the phase change thermal storage device 126 can release the heat therein to alleviate the intermittent nature of solar energy.

[0073] In one embodiment, when a plurality of ultraviolet lamps 120 are included, the ultraviolet lamps 120 are distributed in an array at equal intervals.

[0074] The plurality of ultraviolet lamps 120 equally spaced in an array can evenly purify all the air in the inner air passage, thereby improving the air purification efficiency.

[0075] The number of the ultraviolet lamps 120 may be determined according to the concentration of pollutants in the air in the indoor environment.

[0076] In one embodiment, Figure 2 As shown, the solar ventilation wall 10 further includes: an EPS (Expanded Polystyrene, polystyrene) foam wall 128 .

[0077] The EPS foam wall 128 is disposed on one side of the heavy wall 108 close to the insulation board 114. The EPS foam wall 128 has a highly efficient heat insulation effect and can avoid the fluctuation of the indoor ambient temperature, thereby achieving heat insulation.

[0078] In one embodiment, the heavy wall 108 is fixed to the photovoltaic panel 118 , the phase change thermal storage device 126 , and the EPS foam wall 128 by screws, thereby enhancing the reliability of the solar ventilation wall 10 .

[0079] In one embodiment, the controller includes: a voltage conversion circuit and a voltage stabilization circuit.

[0080] The input end of the voltage conversion circuit is connected to the output end of the photovoltaic panel 118. The voltage conversion circuit can output an electrical signal adapted to the ultraviolet lamp 120 and the fan 124, thereby improving the stability and safety of the circuit.

[0081] The input end of the voltage stabilizing circuit is connected to the output end of the voltage conversion circuit, and the output end of the voltage stabilizing circuit is respectively connected to the ultraviolet lamp 120 and the fan 124. The electrical signals output to the ultraviolet lamp 120 and the fan 124 can obtain more stable electrical signals by first passing through the voltage stabilizing circuit, thereby improving the stability of the circuit.
