Description

Technical Field

[0001] This invention relates to a one-way pressure-controlled solar hot air space, which uses a completely natural and passive method for hot air pressurization and pressure control. Hot air can be input into the hot air space, and its quality and pressurization can be achieved, while its pressure value can be controlled within a certain range. It can be applied to civilian, agricultural, and industrial applications that require hot air, utilize solar energy, and integrate renewable energy. It belongs to the fields of solar energy technology and related environmental protection and energy-saving technologies. Background Technology

[0002] In the industrial and residential sectors, renewable energy technologies such as solar power often appear in the form of a hybrid of active and passive systems, as well as integrated systems utilizing multiple energy technologies. The ultimate design principle is a fully natural passive system, which optimizes energy, environmental, and resource efficiency.

[0003] Solar thermal air technology systems are required in many industrial and civilian applications. These applications often require hot air at a certain pressure and a continuous flow of hot air. Solar thermal air systems typically need to be pressurized to a certain pressure range to be used in practical applications.

[0004] The proper operation of solar energy technology systems often requires parameter control. In reality, industrial and civilian technological systems are mostly composite systems of equipment and automatic control systems. The solar hot air pressure control system is a "secondary technical system" within the overall composite solar energy technology system. To achieve the most rational and optimized approach to energy, environment, and resources, its control system should also be designed to the limits of a fully natural, passive, and zero-energy-consumption technical concept.

[0005] A fully natural, passive system offers optimal energy, environmental, and resource efficiency. The design philosophy of the entire engineering system and all its subsystems should aim for complete naturalness, passivity, and zero energy consumption. Only in this way can optimal energy, environmental, and resource efficiency be achieved. However, in reality, its development and application are insufficient.

[0006] Generally, solar energy technology systems primarily employ active, power-consuming electrical or digital control systems. The development and application of zero-energy, all-natural, and passive control systems designed with a holistic, all-natural approach are insufficient. In other words, the design and development of passive control systems for solar energy technology systems are inadequate. Not only is the concept neglected, but the development of its technical measures also faces certain difficulties and shortcomings. There is a need to develop and apply reasonable and optimized technical measures.

[0007] Therefore, there is significant potential for the application of passive, zero-energy solar thermal air pressurization and control systems. Generating hot air within a set pressure range in a completely natural and passive manner presents a challenging technical problem. Similarly, the related technological systems have considerable room for development and application. Summary of the Invention

[0008] In view of the above difficulties and shortcomings, the present invention provides a one-way plate pressure-controlled solar hot air space, which can input hot air into the hot air space and realize the quality enhancement and pressurization of the hot air, while controlling its pressure value within a certain range.

[0009] The technical solution of this invention is:

[0010] A one-way pressure-controlled solar hot air space, the system composition of which is:

[0011] It consists of the following components: an external air inlet pipe 2, a solar hot air temperature and mass booster collector 3, a solar hot air indoor inlet pipe 4, a solar hot air pressurization space 1, a hot air on / off outlet 12; a one-way pressure control plate 6, a one-way plate rotating wall groove 5, a one-way plate rotating pivot 7, a one-way plate rotating pivot wall frame 8; a south-facing wall auxiliary temperature booster air collector 9, an indoor air inlet 10, and an indoor air outlet 11.

[0012] A one-way plate pressure-controlled solar hot air space, the system structure of which is as follows:

[0013] The external air heating intake structure outside the system structure is:

[0014] The channels are interconnected and connected in sequence. The external air inlet pipe 2 is connected to the solar hot air temperature and mass booster collector 3, which is connected to the solar hot air indoor inlet pipe 4. The solar hot air indoor inlet pipe 4 is connected to the solar hot air booster space 1.

[0015] The hot air intake channel structure of its system is as follows:

[0016] The solar hot air pressurization space 1 is equipped with a hot air opening and closing outlet 12.

[0017] The unidirectional pressure control plate 6 of its system structure is configured as follows:

[0018] The upper end of the one-way pressure plate 6 has an opening and a built-in one-way plate rotation pivot 7. The one-way plate rotation pivot 7 is connected to the one-way plate rotation pivot wall frame 8. The upper end of the one-way pressure plate 6 is built into the groove of the one-way plate rotation wall frame.

[0019] The length and width of the unidirectional pressure control plate 6 are both greater than the maximum length and width of the corresponding hot air inlet channel. This ensures that when the plate surface falls naturally to a plumb bob position, it can cover and seal the hot air inlet of the collector formed by the opening in the south-facing wall. The unidirectional pressure control plate 6 will not rotate outward from the south-facing wall to form a hot air inlet; it can only rotate inward from the south-facing wall to form a hot air inlet.

[0020] The structure of the auxiliary temperature-boosting air collector 9 on the south wall of the system is as follows:

[0021] The south-facing wall auxiliary temperature boosting air collector 9 is installed on the upper part of the south-facing wall of the solar hot air pressurization space 1. The south-facing wall auxiliary temperature boosting air collector 9 is equipped with an indoor air inlet 10 and an indoor air outlet 11, which are connected to the channel of the solar hot air pressurization space 1.

[0022] The technical system process based on the above-described structure of the present invention is detailed in the specific embodiments.

[0023] The technical principles of the above-described structure of the present invention are detailed in the specific embodiments. Attached Figure Description

[0026] The specific implementation of this invention is based on the aforementioned internal and external composition, structure, and structural relationships of the one-way pressure-controlled solar hot air space. Based on this, the invention can input hot air into the hot air space and achieve both mass enhancement and pressurization of the hot air, while controlling its pressure value within a certain range. Its technical system employs two types of collectors. The outdoor solar collector enhances the mass and pressurization of the hot air space. The south-facing auxiliary solar collector can supplement the pressurization of the hot air space and enhance the closing function of the one-way pressure-controlled plate for pressure control. The technical system implements a passive, zero-energy mechanical automatic pressure control system.

[0027] The technical principle of this invention is:

[0028] The principle of natural airflow into the space is:

[0029] Outside air is heated by the solar hot air temperature and mass booster collector 3, causing its temperature to rise. The density difference generates an upward flow driving force, propelling the air into the solar hot air chamber inlet pipe 4. When the hot air generated by the collector reaches sufficient pressure, it can push open the outer surface of the one-way pressure control plate 6, forming a hot air inlet channel. The hot air then enters the solar hot air pressurization space 1.

[0030] Its one-way panel opens inwards in 6 directions.

[0031] The hot air inlet channel of the solar hot air pressurization space 1 is composed of the outlet of the solar hot air indoor inlet pipe 4, the inner plate surface of the one-way pressure control plate 6 which rotates inward to a certain angle around the one-way plate rotation pivot 7 (non-vertical position), and the inner surface of the south-facing wall of the solar hot air pressurization space 1.

[0032] When the thrust of hot air on the outer surface of the one-way pressure control plate 6 is sufficient to push the pressure control plate to rotate around the one-way plate rotation pivot 7 into the solar hot air pressurization space 1, the aforementioned hot air inlet is formed. Hot air thus enters the solar hot air pressurization space 1.

[0033] The solar hot air temperature and mass booster collector 3 creates inward pressure on the outer surface of the one-way plate 6, generating an inward thrust on the one-way plate 6, causing the one-way plate 6 to open inward.

[0034] The principle behind the increased pressure in the solar hot air pressurization space 1 is:

[0035] Hot air flows into the solar hot air pressurization space 1, causing an increase in the air mass and temperature within the space. Simultaneously, the circulating heating effect of the auxiliary temperature-pressurizing air collector 9 on the south-facing wall leads to an increase in the air temperature within the space. These two combined effects, under the conditions of a sealed and thermally insulated space, cause the pressure within the space to gradually increase.

[0036] The principle of its one-way pressure control plate 6 closing the hot air passage is:

[0037] As the pressure inside the solar hot air pressurization space 1 gradually increases, the pressure on the inner surface of the one-way pressure control plate 6 also gradually increases. This creates a pressure difference between the inside and outside of the one-way pressure control plate 6. The pressure on the one-way pressure control plate 6 is the pressure within the solar hot air pressurization space 1, and it gradually increases. When the pressure on the inner surface of the one-way pressure control plate 6 exceeds the pressure on the outer surface, the one-way pressure control plate 6 falls to the plumb bob position, closing the channel for solar hot air from the solar hot air temperature and mass pressurization collector 3 to the solar hot air pressurization space 1. At this time, the pressure on the inner surface of the one-way pressure control plate 6 is the combined pressure of the plate's weight, the increased air mass and temperature rise of the solar hot air temperature and mass pressurization collector 3, and the heating effect of the auxiliary temperature pressurization air collector 9. This combined effect generates an outward thrust on the one-way pressure control plate 6.

[0038] When the pressure on the inner plate of the one-way pressure control plate 6 is greater than the pressure on the outer plate, the outward thrust of the one-way pressure control plate 6 is greater than the inward thrust. The one-way pressure control plate 6 rotates outward around the one-way plate rotation pivot 7 and falls to the plumb bob position, which can close the solar hot air to solar hot air pressurization space 1 channel of the solar hot air temperature and mass pressurization collector 3.

[0039] The auxiliary pressure control principle of its auxiliary temperature boosting air collector 9 is as follows:

[0040] Pressure control is achieved by the weight of the one-way pressure control plate 6, the effect of the hot air temperature and mass booster collector 3, and the combined effect of the auxiliary temperature booster air collector 9 on the south wall. After the one-way pressure control plate 6 closes the hot air passage, the pressure in the space can be controlled within the set range.

[0041] If the auxiliary temperature-boosting air collector 9 is not installed, or the indoor air inlet 10 and indoor air outlet 11 are closed, the thrust of the outer and inner surfaces of the one-way pressure control plate 6 is balanced. The outward thrust is generated solely by the internal pressure of the solar hot air pressurization space 1 and the plate's own weight, while the inward thrust is generated by the hot air flow thrust of the solar hot air temperature and mass boosting collector 3. Under certain settings, if the power of the solar hot air temperature and mass boosting collector 3 is too high, it is necessary to increase the outward thrust to close the hot air passage.

[0042] At this time, the auxiliary temperature-boosting air collector 9 increases the outward thrust of the one-way pressure control plate 6, closing the hot air passage. Simultaneously, the temperature-boosting air collector 9 can continue to operate after the hot air passage is closed, maintaining the temperature and pressure within the solar hot air pressurization space 1 and continuously maintaining the outward-closing state of the one-way pressure control plate 6, thus enhancing its closing effect. In the event of leakage from the sealed solar hot air pressurization space 1 or heat loss due to thermal insulation, the auxiliary temperature-boosting air collector 9 can enhance the closing effect while maintaining the pressurized hot air pressure.

[0043] The principle for maintaining the set pressure in its solar hot air pressurization space 1 is:

[0044] The maximum power of the solar hot air pressurization collector 3, determined by the collector design and the maximum solar irradiance, along with the temperature and mass of the pressurized solar air, determines the maximum pressure on the outer panel. When the pressure on the inner panel, determined by the mass and temperature of the hot air in the solar hot air pressurization space 1 and the cyclic heating effect of the auxiliary temperature pressurization air collector 9, exceeds the maximum pressure on the outer panel, the hot air inlet channel closes, resulting in the sealing of the hot air space in the solar hot air pressurization space 1. The solar hot air pressurization space 1 is equipped with thermal insulation, which maintains the hot air pressure within a set range, ensuring that the pressure is within the set range of the pressure already achieved above the outdoor atmosphere, when the temperature and pressure of the hot air remain relatively constant.

[0045] The auxiliary temperature-boosting air collector 9 increases the air pressure within the space by raising the air temperature. Simultaneously, the auxiliary temperature-boosting air collector 9 also plays a role in the combined control of the hot air pressure within the space. The power and design of the auxiliary temperature-boosting air collector 9 help determine the pressure on the inner surface of the unidirectional pressure control plate 6, thereby ensuring the pressure balance between the inner and outer surfaces of the unidirectional pressure control plate 6 and controlling the internal pressure value of the solar hot air pressurization space 1.

[0046] The one-way pressure control plate 6 has the following one-way closing mechanism:

[0047] The hot air inlet channel is a passage consisting of the outlet of the outside air inlet pipe 2 and the open one-way pressure control plate 6, and has a maximum length and width. This channel is the hot air inlet of the solar collector formed by the opening in the south-facing wall.

[0048] The length and width of the one-way pressure control plate 6 are both greater than the maximum length and width of the corresponding hot air inlet channel. This ensures that when the plate surface falls naturally to a plumb bob position, it can cover and seal the hot air inlet of the collector formed by the opening in the south-facing wall. Therefore, the one-way pressure control plate 6 will not rotate outwards from the south-facing wall to form a hot air inlet; it can only rotate inwards from the south-facing wall to form a hot air inlet, allowing for opening and closing under specific operating conditions.

[0049] The one-way pressure control plate 6 is offset from its plumb bob position. Rotating it inward and upward around the one-way plate rotation pivot 7 will open the hot air inlet channel. Rotating it inward to the plumb bob direction will close the channel.

[0050] Under certain operating conditions, the outer and inner surfaces of the one-way pressure control plate 6 can achieve pressure balance and maintain the inlet channel. At this time, due to the self-weight of the plate, the pressure boosting pressure of the solar hot air pressurization space 1, and the additional pressure of the hot air generated by the auxiliary solar collector, the pressure on the inner plate will be greater than the pressure on the outer plate at a certain moment. The one-way pressure control plate can then rotate outward around the one-way plate rotation pivot 7 and fall to the direction of the plumb bob, closing the hot air inlet channel.

[0051] Its principle of automatic inflation and pressurization circulation after hot air is taken out is:

[0047] Due to its enclosed and thermally insulated design, the solar hot air pressurization space 1 can maintain the pressurization pressure after the channel is closed. At this time, the hot air outlet 12 is closed. When pressurized hot air is needed, the hot air outlet 12 is opened, the pressurized hot air in the solar hot air pressurization space 1 is depressurized, and the pressurized hot air flows out.

[0052] At this point, the pressure on the inner and outer surfaces of the one-way pressure control plate 6 gradually becomes unbalanced. The pressure on the inner surface of the one-way pressure control plate 6 gradually decreases, resulting in a gradual decrease in the outward thrust of the one-way pressure control plate 6 and a gradual increase in the inward thrust of the one-way pressure control plate 6.

[0053] When the inward thrust on the one-way pressure control plate 6 is sufficient to push the pressure control plate to rotate inward around its rotation axis, the hot air inlet opens. The outdoor atmospheric pressure hot air is heated and pressurized by the solar hot air temperature and mass booster collector 3, and enters the solar hot air pressurization space 1 through the outlet of the outside air inlet pipe 2 and the channel formed by the one-way pressure control plate 6.

[0054] Due to the sealed and thermally insulated space, the air mass and temperature entering the solar hot air pressurization space 1 increase, causing the pressure within the space to gradually increase again. This re-establishes a pressure difference with opposing forces inside and outside the one-way pressure control plate. When the pressure on the inner surface of the one-way pressure control plate 6 exceeds the pressure on the outer surface, it falls to the plumb bob position under gravity, which again closes the entrance to the solar hot air pressurization space 1, whereby the solar hot air heated by the solar hot air temperature and mass pressurization collector 3 is introduced, initiating the second pressure-maintaining cycle.

[0055] The working process of the technical system of the present invention is as follows:

[0056] The system process of the present invention includes a series of cyclic processes such as intake pressurization, closed pressure maintenance, pressure relief and utilization, and cyclic intake pressurization.

[0057] Its intake boosting process is as follows:

[0058] Outside air is heated by the solar hot air temperature and mass booster collector 3, and the temperature rises. The density difference generates an upward flow driving force. When the thrust on the one-way pressure plate 6 is sufficient to push the pressure plate to rotate around the one-way plate rotation pivot 7 into the solar hot air booster space 1, a hot air inlet is formed. The hot air enters the solar hot air booster space 1 through the channel formed by the one-way plate and the heat collector air inlet.

[0059] As the pressure within the space gradually increases, the pressure on the inner surface of the one-way pressure control plate 6 also gradually increases. A pressure difference is generated between the inside and outside of the one-way pressure control plate 6. When the pressure on the inner surface of the one-way pressure control plate 6 is greater than the pressure on the outer surface, the thrust generated by the pressure difference, combined with the force of the composite plate's own weight, causes the one-way pressure control plate 6 to fall to the plumb bob position, closing the solar hot air pressure boosting space 1 channel of the solar hot air temperature and mass boosting collector 3.

[0060] The process by which the auxiliary temperature-boosting air collector 9 circulates and heats the hot air in the solar hot air pressurization space 1, and the auxiliary one-way pressure control plate 6 closes its channel, is as follows:

[0061] Hot air from the solar hot air pressurization space 1 enters the auxiliary temperature-pressurizing air collector 9 on the south wall through the indoor air inlet 10. After being heated by the sun within the collector, its temperature further increases, and it re-enters the solar hot air pressurization space 1 through the indoor air outlet 11. Through this process, the auxiliary temperature-pressurizing air collector 9 circulates and heats the hot air in the solar hot air pressurization space 1, causing the hot air to pressurize due to the increased temperature. This pressurization leads to an increase in pressure on the inner surface of the one-way pressure control plate 6, generating a thermal pressure thrust from the hot air. This thrust, combined with the plate's own weight, closes the channel for the solar hot air from the solar hot air temperature and mass pressurizing collector 3 to the solar hot air pressurization space 1.

[0062] Its closed-loop pressure maintenance process is as follows:

[0063] After the hot air passage is closed by the one-way control plate 6, the internal pressure of the solar hot air pressurization space 1 is the same as the pressurized hot air pressure from the collector. Due to the sealed space and thermal insulation, the hot air space can maintain the pressurized pressure. The auxiliary temperature pressurization air collector 9 circulates and heats the hot air in the space, which can generate an auxiliary pressurization effect on the outward pushing pressure of the inner plate surface of the one-way pressure control plate 6, enhancing the closing effect of the one-way pressure control plate 6 on the hot air passage. That is, it enhances the spatial sealing of the hot air space. During the sealing and pressure maintenance process, the hot air opening and closing outlet 12 is in the closed state.

[0064] The pressure relief and extraction process is as follows:

[0065] When pressurized hot air is used, the hot air outlet 12 is opened, the pressurized hot air in the solar hot air pressurization space 1 is depressurized, and the pressurized hot air flows out.

[0066] Its cyclic intake boosting process is as follows:

[0067] As the pressure decreases after extraction, the pressure on the inner surface of the one-way pressure control plate 6 gradually decreases. When the pressure drops below that on the outer surface of the one-way pressure control plate 6, the outside air is heated by the solar hot air temperature and mass booster collector 3, causing its temperature to rise. This increase in temperature generates an upward flow driving force due to the density difference. When the thrust on the one-way pressure control plate 6 is sufficient to push the pressure control plate to rotate around the one-way plate rotation pivot 7 into the solar hot air booster space 1, a hot air inlet is formed. The hot air enters the solar hot air booster space 1 through the channel formed by the one-way plate and the collector air inlet. The cycle of storing and extracting pressurized hot air in the solar hot air booster space 1 begins, and the intake and pressurization process is repeated.

[0068] The technical system function of this invention is:

[0069] Hot air can be introduced into the hot air space, and the hot air can be improved in quality and pressure, while its pressure value can be controlled within a certain range.

[0070] The technical and application features of this invention are:

[0071] This invention utilizes a completely natural method for hot air pressurization and pressure control. The system design is simple, the structure is straightforward, manufacturing is easy, and the cost is low. It operates entirely naturally and passively, resulting in low operating costs. This passive, zero-energy mechanical pressure control replaces power-consuming, high-investment, and high-maintenance electrical or digital automatic control systems.

[0072] This invention features a solar collector with two functions. The outdoor solar collector can be modularly stacked to meet pressure and power requirements. The south-facing auxiliary solar collector can pressurize the hot air space and enhance the closing function of the one-way pressure control plate.

[0073] The technical system of this invention is applied in the following situations:

[0074] This invention can enhance the quality and pressurize solar thermal air, providing high-temperature, high-pressure solar thermal air with pressure controlled within a certain range. It can be applied in various civil, industrial, and agricultural production applications requiring high-pressure thermal air, such as heating, drying, and power generation using thermal air.

[0075] The application prospects of the technical system of this invention are:

[0076] Passive energy and industrial systems offer significant advantages in energy efficiency, environmental friendliness, and materials performance. This system falls within these technological fields and possesses promising development and application prospects.

[0077] The composite equipment system and control system are technical systems, with the control system employing a passive approach. This passive control system, as a secondary system within the overall composite technology system, achieves zero energy consumption and optimal energy, environmental, and resource efficiency for the entire system, offering significant development potential and application prospects.
