Abstract
Description
Technical Field
[0001] This invention relates to a solar-powered chimney and its automatic adjustment method, system, and storage medium for operating modes, belonging to the field of renewable energy technology. Background Technology
[0002] With continuous urbanization and a surge in energy demand, the increasing scarcity of conventional energy sources and the growing environmental problems caused by energy consumption have made energy conservation and emission reduction essential for ensuring healthy and stable economic and social development. Fully utilizing renewable energy to create a comfortable and healthy building thermal environment and reduce building energy consumption has become one of the main directions for the development of the HVAC industry. In recent years, the application of renewable energy integrated with buildings has been strongly promoted. Solar energy, as a clean and pollution-free renewable energy source, has the characteristics of being unrestricted by geographical location and having an energy quality that matches the energy consumption needs of buildings. Therefore, adapting to local conditions, fully utilizing renewable energy sources such as solar energy, improving building energy efficiency, and employing passive solar energy utilization technologies are effective measures to promote economic development.
[0003] Trombe walls and sloping roof solar chimneys can effectively reduce building heating and air conditioning energy consumption and improve indoor thermal and humidity environments. However, Trombe walls lack sufficient natural ventilation power in summer, leading to overheating; sloping roof solar chimneys cannot be used for winter heating. Summarizing these advantages and disadvantages, a combined solar chimney is proposed. This combined chimney increases the solar heat collection area in summer, provides stronger natural ventilation than Trombe walls, and can also be used for winter heating, making it a promising building structure.
[0004] However, this structural form is more complex and has more air vents compared to simpler forms like Trombe walls and sloping roof solar chimneys. For residents lacking structural knowledge, manually controlling the vents can backfire, exacerbating indoor thermal problems and negatively impacting the living experience. Existing research is limited on the operation modes and vent control of combined solar chimneys. Patent CN108317652A applies a combined solar chimney structure but doesn't detail how to control the vents. This invention collects indoor and outdoor temperatures, as well as the temperature at the building's air inlet, and automatically controls the opening and closing of the vents based on the temperature difference, reducing human error, improving the living environment, and ensuring comfort.

[0058] Example 2:
[0059] Figure 6 This is a flowchart illustrating an automatic adjustment method for the operation mode of a solar chimney according to Embodiment 2 of the present invention. This flowchart only shows the logical sequence of the method in this embodiment. Provided there are no conflicts, different methods may be used in other possible embodiments of the present invention. Figure 6 Complete the steps shown or described in the order indicated.
[0060] The automatic adjustment method for solar chimney operation mode provided in this embodiment can be applied to a terminal and can be executed by a solar chimney operation mode automatic adjustment system. This system can be implemented by software and / or hardware and can be integrated into the terminal, such as any smartphone, tablet, or computer device with communication capabilities. See also... Figure 6 The method implemented in this way specifically includes the following steps:
[0061] Step 1: Collect outdoor temperature T1, indoor temperature T2, and temperature T3 at the building's air inlet;
[0062] Taking the solar chimney in Embodiment 1 as an example, the outdoor temperature T1 is measured by the first temperature sensor 8-1; the indoor temperature T2 is measured by the second temperature sensor 8-2; and the temperature T3 at the air inlet of the building is measured by the third temperature sensor 8-3. The first temperature sensor 8-1, the second temperature sensor 8-2, and the third temperature sensor 8-3 transmit the measured outdoor temperature T1, indoor temperature T2, and air inlet temperature T3 to the temperature acquisition unit 9, which stores them. The temperature acquisition unit 9 then transmits the outdoor temperature T1, indoor temperature T2, and air inlet temperature T3 to the signal processor 10.
[0063] Step 2: Compare the indoor temperature T1, outdoor temperature T2, and the temperature at the building's air inlet T3 with the preset temperature judgment parameter T. A T B T C T D To make comparisons and determine the operating mode of solar chimneys;
[0064] Taking the solar chimney in Embodiment 1 as an example, after receiving the outdoor temperature T1, indoor temperature T2, and the temperature T3 at the air inlet of the building sent by the temperature acquisition unit 9, the signal processor 10 compares them with the preset temperature judgment parameter T. A T B T C T D By comparing the two, it can be determined which operating mode the solar chimney should currently be activated.
[0065] See Figure 7 The method for determining the operating mode of a solar chimney includes the following steps:
[0066] Step A: Determine if T1 < T A If the result is yes, proceed to step B; otherwise, proceed to step D.
[0067] Step B: Determine if T3 - T2 > T B If the result is yes, then the operation mode of the solar chimney is determined to be operation mode one and operation mode one is started; otherwise, proceed to step C.
[0068] Step C: Determine if T3 - T2 ≤ T B If the result is yes, then determine the operation mode of the solar chimney as operation mode two and start operation mode two; otherwise, return to step B.
[0069] Step D: Determine T A ≤T1≤T C If the result is yes, then the operation mode of the solar chimney is determined to be operation mode three and operation mode three is started; otherwise, proceed to step E.
[0070] Step E: Determine if T2 ≤ T D If the result is yes, then the operation mode of the solar chimney is determined to be operation mode four and operation mode four is started; otherwise, while starting operation mode four, auxiliary cooling is carried out indoors.
[0071] Among them, the temperature determination parameter T A T B T C T D The initial default values are set to 20℃, 5℃, 28℃, and 27℃ respectively.
[0072] Step 3: Output the corresponding execution signal to the electric actuator according to the operating mode to control the opening or closing of the corresponding air valve, so as to realize the automatic adjustment of the operating mode of the solar chimney;
[0073] Taking the solar-powered chimney in Embodiment 1 as an example, the signal processor 10 outputs corresponding execution signals to each electric actuator according to the determined operating mode:
[0074] Operating mode one corresponds to the first execution signal: the first electric actuator 6-1 connected to the first air valve 7-1 controls the first air valve 7-1 to close; the second electric actuator 6-2 connected to the second air valve 7-2 controls the second air valve 7-2 to open; the third electric actuator 6-3 connected to the third air valve 7-3 controls the third air valve 7-3 to close; the fourth electric actuator 6-4 connected to the fourth air valve 7-4 controls the fourth air valve 7-4 to open; and the fifth electric actuator 6-5 connected to the fifth air valve 7-5 controls the fifth air valve 7-5 to close.
[0075] Operating mode two corresponds to the second execution signal: the first electric actuator 6-1 connected to the first air valve 7-1 controls the first air valve 7-1 to close; the second electric actuator 6-2 connected to the second air valve 7-2 controls the second air valve 7-2 to close; the third electric actuator 6-3 connected to the third air valve 7-3 controls the third air valve 7-3 to close; the fourth electric actuator 6-4 connected to the fourth air valve 7-4 controls the fourth air valve 7-4 to close; and the fifth electric actuator 6-5 connected to the fifth air valve 7-5 controls the fifth air valve 7-5 to close.
[0076] Operating mode three corresponds to the third execution signal: the first electric actuator 6-1 connected to the first air valve 7-1 controls the first air valve 7-1 to open; the second electric actuator 6-2 connected to the second air valve 7-2 controls the second air valve 7-2 to close; the third electric actuator 6-3 connected to the third air valve 7-3 controls the third air valve 7-3 to close; the fourth electric actuator 6-4 connected to the fourth air valve 7-4 controls the fourth air valve 7-4 to open; and the fifth electric actuator 6-5 connected to the fifth air valve 7-5 controls the fifth air valve 7-5 to open.
[0077] Operating mode four corresponds to the fourth execution signal: the first electric actuator 6-1 connected to the first air valve 7-1 controls the first air valve 7-1 to open; the second electric actuator 6-2 connected to the second air valve 7-2 controls the second air valve 7-2 to close; the third electric actuator 6-3 connected to the third air valve 7-3 controls the third air valve 7-3 to open; the fourth electric actuator 6-4 connected to the fourth air valve 7-4 controls the fourth air valve 7-4 to close; and the fifth electric actuator 6-5 connected to the fifth air valve 7-5 controls the fifth air valve 7-5 to close.
[0078] Taking the solar chimney in Example 1 as an example, when the first operating mode is started, the signal processor 10 sends the first execution signal to each electric actuator: controls the second air valve 7-2 and the fourth air valve 7-4 to open, and controls the first air valve 7-1, the third air valve 7-3 and the fifth air valve 7-5 to close.
[0079] like Figure 2As shown, the first operating mode is used for daytime heating in winter. During the winter daytime, under the action of solar radiation, the air in the second heat channel 2-2 is heated. Under the action of thermal pressure, the hot air in the second heat channel 2-2 enters the room through the second air valve 7-2, and the cold air in the room enters the second heat channel 2-2 through the fourth air valve 7-4 and is heated in the second heat channel 2-2. The air in the room and the air in the second heat channel 2-2 circulate with each other, thereby achieving the effect of daytime heating in winter.
[0080] When operating mode two is started, the signal processor 10 sends a second execution signal to each electric actuator: controlling the first air valve 7-1, the second air valve 7-2, the third air valve 7-3, the fourth air valve 7-4, and the fifth air valve 7-5 to close;
[0081] like Figure 3 As shown, the second operating mode is used for keeping warm at night in winter. At night in winter, the indoor air does not exchange heat with the first hot channel 2-1, the second hot channel 2-2, and the outdoor air, thereby achieving the effect of keeping warm at night in winter.
[0082] When operating mode three is started, the signal processor 10 sends a third execution signal to each electric actuator: controls the first air valve 7-1, the fourth air valve 7-4, and the fifth air valve 7-5 to open, and controls the second air valve 7-2 and the third air valve 7-3 to close.
[0083] like Figure 4 As shown, the third operating mode is used for natural ventilation in summer. In summer, fresh outdoor air enters the room through the fifth air valve 7-5, interacts and circulates with the indoor air, and enters the second hot channel 2-2 through the fourth air valve 7-4. The air in the second hot channel 2-2 is discharged upward through the first air valve 7-1 under thermal pressure, thus achieving the effect of natural ventilation in summer.
[0084] When operating mode four is started, the signal processor 10 sends a fourth execution signal to each electric actuator: controls the first air valve 7-1 and the third air valve 7-3 to open, and controls the second air valve 7-2, the fourth air valve 7-4, and the fifth air valve 7-5 to close.
[0085] like Figure 5 As shown, the fourth operating mode is used to prevent overheating in summer. In summer, hot outdoor air enters the second hot channel 2-2 through the third air valve 7-3 and is discharged upward through the first air valve 7-1 under thermal pressure. At the same time, it can take away some heat and reduce the transfer of heat from the air in the second hot channel 2-2 to the room, thereby achieving the function of preventing overheating in summer.
[0086] In this embodiment, by collecting indoor and outdoor temperatures as well as the air inlet of the building, the operating mode of the solar chimney can be determined based on the indoor and outdoor temperature difference, and the operating mode of the solar chimney can be automatically adjusted.

[0089] Temperature acquisition module: used to collect outdoor temperature T1, indoor temperature T2, and temperature T3 at the building's air inlet;
