Description

Technical Field

[0001] This application relates to the field of dehumidifier technology, specifically to a control method, device, dehumidification system, and storage medium for a dehumidification system. Background Technology

[0002] In the battery manufacturing industry, low dew point rotary dehumidification systems are commonly used to control the humidity of the environment during battery production and storage. Because humidity requirements are extremely stringent during battery production and storage, and humidity is highly susceptible to external disturbances in ultra-low humidity environments, low dew point rotary dehumidification systems need to possess strong stability and a certain response speed.

[0003] The low dew point rotary dehumidification system in related technologies has many control parameters, and there are linear and nonlinear relationships between these parameters. In addition, the wet load of the low dew point rotary dehumidification system will change with the change of the controlled area. Therefore, the low dew point rotary dehumidification system has poor stability and high energy consumption. Summary of the Invention

[0004] In view of the above problems, this application provides a control method, device, dehumidification system, electronic device and storage medium for a dehumidification system, which can solve the technical problems of poor stability and high energy consumption of low dew point rotary dehumidification systems in related technologies.

[0005] In a first aspect, this application provides a control method for a dehumidification system, comprising: acquiring a first dew point temperature at the air outlet of a dehumidifier and a second dew point temperature in a target space connected to the air outlet; adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference between the first dew point temperature and the second dew point temperature; and controlling the second dew point temperature to reach a preset dew point temperature based on dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature.

[0006] In the technical solution of this invention embodiment, based on the temperature difference between the first dew point temperature at the dehumidifier's air outlet and the second dew point temperature in the target space connected to the air outlet, the first dew point temperature is adjusted to be less than or equal to the second dew point temperature. Based on the dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature, the second dew point temperature is controlled to reach a preset dew point temperature. Before controlling the dew point temperature of the target space, the difference between the dew point temperature of the air supplied to the target space and the current dew point temperature in the target space is determined. This avoids the dew point temperature of the air supplied to the target space being higher than the current dew point temperature in the target space, or a large difference between the two temperatures. This improves the stability of the dew point temperature in the target space during the dew point temperature control process and reduces the energy consumption of the dehumidification system during the dew point temperature control process.

[0007] In some embodiments, adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference between the first and second dew point temperatures includes: adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference when the first dew point temperature is greater than the second dew point temperature. In this embodiment, before controlling the dew point temperature of the target space, adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference when it is determined that the first dew point temperature is greater than the second dew point temperature can reduce large fluctuations in the dew point temperature within the target space during the dew point temperature control process, and can also reduce energy consumption during the dew point temperature control process.

[0008] In some embodiments, adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference when the first dew point temperature is greater than the second dew point temperature includes: adjusting the first dew point temperature to satisfy the condition that the temperature difference is less than or equal to the preset threshold when the first dew point temperature is greater than the second dew point temperature and the temperature difference is greater than a preset threshold.

[0009] In this embodiment, before controlling the dew point temperature of the target space, if it is determined that the first dew point temperature is greater than the second dew point temperature, it is determined whether the first dew point temperature is greater than the second dew point temperature and whether the temperature difference between the two is greater than a preset threshold. Then, the temperature difference is used to adjust the first dew point temperature to meet the condition that the temperature difference is less than or equal to the preset threshold. This can more accurately control the difference between the supply air dew point temperature in the target space and the dew point temperature required by the target space, and improve the stability of the dehumidification system in the process of controlling the dew point temperature.

[0010] In some embodiments, adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference includes: determining the regulating liquid temperature of the coolant used in the dehumidifier and the regulating temperature of the heater that dehumidifies the dehumidifying impeller in the dehumidifier based on the temperature difference; and adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the regulating liquid temperature and the regulating temperature. In this embodiment, the dew point temperature of the air supplied to the target space can be precisely adjusted by regulating the cooling liquid temperature of the dehumidifier and the regulating temperature of the heater that dehumidifies the dehumidifying impeller in the dehumidifier.

[0011] In some embodiments, determining the regulating liquid temperature of the cooling water used in the dehumidifier and the regulating temperature of the heater for dehumidifying the dehumidifying impeller in the dehumidifier based on the temperature difference includes: determining a first regulating liquid temperature of the coolant used by at least one surface cooler in the dehumidifier based on the temperature difference; and determining a first regulating temperature of the heater for dehumidifying at least one dehumidifying impeller in the dehumidifier based on the temperature difference. In this embodiment, by controlling the regulating liquid temperature of the coolant used by one or more surface coolers in the dehumidifier and controlling the regulating temperature of one or more heaters in the dehumidifier, not only can the dew point temperature of the air supplied to the target space be precisely adjusted, but also efficient energy saving can be achieved.

[0012] In some embodiments, before controlling the second dew point temperature to reach a preset dew point temperature based on the dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature, the method includes: determining the difference between the current second dew point temperature and the preset dew point temperature; determining a second regulated liquid temperature of the coolant used by at least one surface cooler in the dehumidifier based on the difference; and determining a second regulated temperature of the heater for dehumidifying at least one dehumidifying impeller in the dehumidifier based on the difference.

[0013] In this embodiment, by controlling the regulating temperature of the coolant used by one or more surface coolers in the dehumidifier, and by controlling the regulating temperature of one or more heaters in the dehumidifier, the dew point temperature in the target space can be precisely regulated.

[0014] In some embodiments, controlling the second dew point temperature to reach a preset dew point temperature based on the dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature includes: adjusting the second dew point temperature to the preset dew point temperature based on the second regulating liquid temperature, the second regulating temperature, and the adjusted first dew point temperature. In this embodiment, by using the adjusted supply dew point of the target space during the dew point temperature adjustment process, large fluctuations in the dew point temperature within the target space during the dew point temperature control process can be reduced, and energy consumption during the dew point temperature control process can also be reduced.

[0015] Secondly, an embodiment of the present invention provides a control device for a dehumidification system, comprising: an acquisition unit for acquiring a first dew point temperature at the air outlet of a dehumidifier and a second dew point temperature in a target space connected to the air outlet; an adjustment unit for adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference between the first dew point temperature and the second dew point temperature; and a control unit for controlling the second dew point temperature to reach a preset dew point temperature based on dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature.

[0016] Thirdly, an embodiment of the present invention provides a dehumidification system, comprising: a dehumidifier and a control device connected to the dehumidifier; the dehumidifier is used to input gas into a target space connected to the air outlet of the dehumidifier; the control device is used to acquire a first dew point temperature at the air outlet of the dehumidifier and a second dew point temperature in the target space connected to the air outlet; adjust the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference between the first dew point temperature and the second dew point temperature; and control the second dew point temperature to reach a preset dew point temperature based on dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature.

[0017] Fourthly, an embodiment of the present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, it implements the method described in the first aspect.

[0018] Fifthly, embodiments of the present invention provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the method described in the first aspect.

[0035] Currently, in the battery manufacturing industry, low dew point rotary dehumidification systems are commonly used to control the humidity of the environment during battery production and storage. Because humidity requirements are extremely stringent during battery production and storage, and humidity is highly susceptible to external disturbances in ultra-low humidity environments, low dew point rotary dehumidification systems need to possess strong stability and a certain response speed. Related technologies for low dew point rotary dehumidification systems involve numerous control parameters, and these parameters exhibit both linear and nonlinear relationships. Furthermore, the moisture load of the low dew point rotary dehumidification system varies with changes in the controlled area, resulting in poor stability and high energy consumption.

[0036] To improve the quality of battery components, vehicle components, or other products that require humidity control, high requirements are typically placed on the stability and responsiveness of dehumidification systems.

[0037] To improve the stability of a dehumidification system, this application designs a control method for a dehumidification system. The method includes: acquiring a first dew point temperature at the air outlet of the dehumidifier and a second dew point temperature in a target space connected to the air outlet; adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference between the first dew point temperature and the second dew point temperature; and controlling the second dew point temperature to reach a preset dew point temperature based on dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature.

[0038] Before controlling the dew point temperature of the target space, this application first determines the difference between the dew point temperature of the air supplied to the target space and the current dew point temperature in the target space. It can determine in real time whether the dew point temperature of the air supplied to the target space is higher than the current dew point temperature in the target space, or whether there is a large temperature difference between the two. Then, it controls the dew point temperature of the air supplied to the target space to be less than or equal to the current dew point temperature in the target space. This not only improves the stability of the dew point temperature in the target space during the dew point temperature control process, but also reduces the energy consumption of the dehumidification system during the dew point temperature control process.

[0039] This application is not limited to the application scenarios listed above. In any other application scenario that uses a dehumidification system for humidity control, the humidity in the production or storage space can be controlled using the method provided in this application. This method not only improves the stability of the dehumidification system and maximizes customer satisfaction, but also reduces energy waste and has advantages such as minimal limitations and high versatility.

[0040] The specific process of the control method for the dehumidification system of this application is described in detail below through specific embodiments. See also Figure 1 The flowchart shown illustrates the control method for the dehumidification system, which specifically includes the following steps:

[0041] S101, obtain the first dew point temperature at the dehumidifier's air outlet and the second dew point temperature in the target space connected to the air outlet;

[0042] S102, based on the temperature difference between the first dew point temperature and the second dew point temperature, adjust the first dew point temperature to be less than or equal to the second dew point temperature;

[0043] S103, based on the dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature, control the second dew point temperature to reach the preset dew point temperature.

[0044] Specifically, in this embodiment of the invention, the target space includes a production workshop, a storage workshop, or other spaces where humidity control is required. For example... Figure 3 As shown, the current dew point temperature T2 (first dew point temperature) of the air outlet can be obtained through a humidity sensor installed at the dehumidifier's air outlet. The current dew point temperature T1 (second dew point temperature) of the workshop can be obtained through a humidity sensor installed inside the workshop. The temperature difference between the first dew point temperature and the second dew point temperature is determined. When T2 > T1 is detected, the first dew point temperature T2 needs to be adjusted to be less than or equal to the second dew point temperature T1.

[0045] In one example, when T2 > T1 - Δt is detected, the first dew point temperature T2 needs to be adjusted to be less than or equal to the second dew point temperature T1. Here, Δt is a real number greater than zero, and Δt is a preset temperature difference value.

[0046] After adjusting the first dew point temperature T2 to be less than or equal to the second dew point temperature T1, based on the dew point adjustment parameters controlling the second dew point temperature and the adjusted first dew point temperature, the second dew point temperature can be controlled to reach the preset dew point temperature in a relatively short time, reducing the fluctuation of the dew point temperature in the target space during the dew point temperature control process. Furthermore, it ensures that the humidity in the target space remains within a preset range, meeting the product's production quality or storage environment requirements.

[0047] In this embodiment of the invention, before controlling the dew point temperature of the target space, the difference between the dew point temperature of the air supplied to the target space and the current dew point temperature in the target space is determined. This allows for real-time determination of whether the dew point temperature of the air supplied to the target space is higher than the current dew point temperature in the target space, or whether there is a significant temperature difference between the two. Then, the dew point temperature of the air supplied to the target space is controlled to be less than or equal to the current dew point temperature in the target space. This not only improves the stability of the dew point temperature in the target space during the dew point temperature control process, but also reduces the energy consumption of the dehumidification system during the dew point temperature control process.

[0048] This invention also provides a control method for a dehumidification system, such as... Figure 2 As shown, the method specifically includes the following steps:

[0049] S201, obtain the first dew point temperature at the dehumidifier's air outlet and the second dew point temperature in the target space connected to the air outlet.

[0050] S202, when the first dew point temperature is greater than the second dew point temperature, the first dew point temperature is adjusted to be less than or equal to the second dew point temperature based on the temperature difference.

[0051] Specifically, in the embodiments of this application, such as Figure 3 As shown, the temperature difference between the first dew point temperature and the second dew point temperature is determined. When T2 > T1 is detected, the first dew point temperature T2 needs to be adjusted to be less than or equal to the second dew point temperature T1. This will keep the supply air dew point temperature in the workshop below the current dew point temperature in the workshop, and the dew point temperature in the workshop can be kept within a stable range. The stability of humidity in the workshop will also be greatly improved.

[0052] S203, based on the dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature, control the second dew point temperature to reach the preset dew point temperature.

[0053] Steps S201 and S203 have been described in detail above and will not be repeated here.

[0054] In one or more embodiments of this application, adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference when the first dew point temperature is greater than the second dew point temperature includes:

[0055] When the first dew point temperature is greater than the second dew point temperature and the temperature difference is greater than a preset threshold, the first dew point temperature is adjusted to satisfy the condition that the temperature difference is less than or equal to the preset threshold based on the temperature difference.

[0056] Specifically, such as Figure 3 As shown, for example, when T2 > T1 - Δt is detected, the first dew point temperature T2 needs to be adjusted to be less than or equal to the second dew point temperature T1. Here, Δt is a real number greater than zero, and Δt is a preset temperature difference value. Δt here is an empirical value; in one example, Δt can be 3℃. In this embodiment, before controlling the dew point temperature of the target space, if it is determined that the first dew point temperature T2 is greater than the second dew point temperature T1, it is determined whether the first dew point temperature is greater than the second dew point temperature and whether the temperature difference between them is greater than a preset threshold Δt. Then, the temperature difference is used to adjust the first dew point temperature T2 to satisfy the condition that the temperature difference T2 - T1 is less than or equal to the preset threshold Δt. This allows for more precise control of the difference between the supply air dew point temperature and the required dew point temperature in the target space, improving the stability of the dehumidification system during dew point temperature control.

[0057] In one or more embodiments of this application, adjusting the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference includes:

[0058] The regulating temperature of the coolant used in the dehumidifier and the regulating temperature of the heater that dehumidifies the dehumidification impeller in the dehumidifier are determined based on the temperature difference.

[0059] Based on the regulating liquid temperature and the regulating temperature, the first dew point temperature is adjusted to be less than or equal to the second dew point temperature.

[0060] Specifically, in this embodiment, the coolant can be water or other liquids used for cooling, and the heater includes a steam heater or an electric heater. The dehumidifier cools the gas entering the dehumidifier using the coolant and dries the dehumidification impeller in the dehumidifier by using the heater. Based on the temperature difference, the regulating temperature of the coolant and the regulating temperature of the heater that dehumidifies the dehumidification impeller in the dehumidifier are determined, which can precisely regulate the dew point temperature of the air supplied to the target space.

[0061] In one or more embodiments of this application, determining the regulating liquid temperature of the cooling water used in the dehumidifier and the regulating temperature of the heater for dehumidifying the dehumidifying impeller in the dehumidifier based on the temperature difference includes:

[0062] Based on the temperature difference, determine the first regulating liquid temperature of the coolant used by at least one surface cooler in the dehumidifier;

[0063] Based on the temperature difference, the first adjustment temperature of the heater for dehumidifying at least one dehumidifying impeller in the dehumidifier is determined.

[0064] Specifically, in the embodiments of this application, such as Figure 3 As shown, water is used as a coolant in the surface cooler to cool the air entering the dehumidifier. A steam heater is used to dry the dehumidifying impellers in the dehumidifier that adsorb moisture. The dehumidifier includes three surface coolers: a front surface cooler, a middle surface cooler, and a rear surface cooler. It also includes two dehumidifying impellers: a primary dehumidifying impeller and a secondary dehumidifying impeller. Each impeller is dried by a steam heater. In this embodiment, by controlling the temperature of the coolant used in one or more surface coolers in the dehumidifier, and by controlling the temperature of one or more heaters in the dehumidifier, the dew point temperature of the air supplied to the target space can be precisely adjusted, and efficient energy saving can be achieved.

[0065] In one or more embodiments of this application, before controlling the second dew point temperature to reach a preset dew point temperature based on the dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature, the process includes:

[0066] Determine the difference between the current second dew point temperature and the preset dew point temperature;

[0067] Based on the difference, a second regulating liquid temperature of the coolant used by at least one surface cooler in the dehumidifier is determined;

[0068] Based on the difference, a second regulating temperature is determined for the heater of at least one dehumidifying impeller in the dehumidifier.

[0069] Specifically, in the embodiments of this application, such as Figure 3 As shown, for example, if the current second dew point temperature T1 is determined to be -28℃, the difference between it and the preset dew point temperature -32℃ is 4℃. In this case, it is necessary to lower the second dew point temperature T1 within the workshop. Based on the 4℃ difference, by controlling the temperature of the coolant used in the middle and rear surface coolers of the dehumidifier, and by controlling the temperature of the heater connected to the secondary dehumidification impeller within the dehumidifier, the dew point temperature T1 in the target space can be precisely adjusted to reach the preset dew point temperature of -32℃.

[0070] In one or more embodiments of this application, controlling the second dew point temperature to reach a preset dew point temperature based on the dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature includes:

[0071] Based on the second regulating liquid temperature, the second regulating temperature, and the adjusted first dew point temperature, the second dew point temperature is adjusted to the preset dew point temperature.

[0072] Specifically, for example, if the first dew point temperature before adjustment is -26°C, the current second dew point temperature T1 in the workshop is -28°C, and the first dew point temperature after adjustment is -30°C, then based on the second regulating liquid temperature, the second regulating temperature, and the adjusted first dew point temperature of -30°C, the second dew point temperature of -28°C is adjusted to a preset dew point temperature of -32°C. Compared to related technologies that do not preprocess the first dew point temperature T2, the embodiments of this application not only reduce the large fluctuations in the dew point temperature within the target space during the dew point temperature control process, but also reduce the energy consumption during the dew point temperature control process.

[0073] Dehumidification systems in related technologies have numerous control parameters, and these parameters exhibit both linear and nonlinear relationships that influence each other. Furthermore, the system's moisture load dynamically changes with the activities in the controlled area, such as... Figure 5 As shown, the dehumidification system exhibits poor stability in humidity control, specifically, significant fluctuations in the workshop dew point T1. Furthermore, current low-dew-point rotary dehumidification systems primarily employ PID (Proportional Integral Derivative) control. While PID control offers strong adaptability and robustness for simple systems with low inertia and weak coupling, it is not well-suited for low-dew-point rotary dehumidification systems. For example... Figure 5 As shown, due to the strong inertia of the dehumidification system, the following characteristics of PID control can easily lead to a strong time delay in the system, resulting in large fluctuations in the regeneration temperature T3 used to dry the rotor in the dehumidification system.

[0074] To solve the above-mentioned technical problems, based on the above embodiments, in one or more embodiments of this application, such as Figure 4 As shown, the control method for the above dehumidification system also includes:

[0075] 1. Obtain the workshop dew point temperature T1 and the dew point temperature T2 of the dehumidifier's supply air based on the sampling unit;

[0076] 2. Compare whether T2 is less than or equal to T1-3; if yes, adjust the workshop dew point temperature T1 based on the microcontroller to keep T1 within the preset dew point temperature range; if no, adjust the supply air dew point temperature T2 based on the microcontroller to reduce the value of T2.

[0077] 3. Detect the current value of T2 based on the humidity detector, and then proceed to step 2.

[0078] In this embodiment of the application, by controlling the dew point of the dehumidifier's supply air, the problem of the supply air dew point affecting the dew point temperature in the workshop and causing abnormal humidity in the workshop can be solved. Figure 6As shown, the control method of the dehumidification system based on this application can reduce the fluctuation range of the workshop dew point temperature T1 and significantly improve the stability of the output parameters. The fluctuation range of the regeneration temperature T3 is also greatly reduced, enabling low-cost and stable operation of the low dew point rotary dehumidification system.

[0079] This invention also provides a control device for a dehumidification control system, which is used to execute the control methods for the dehumidification control systems provided in the above embodiments, such as... Figure 7 As shown, the device includes:

[0080] The acquisition unit 702 acquires the first dew point temperature at the dehumidifier's air outlet and the second dew point temperature in the target space connected to the air outlet.

[0081] The adjustment unit 704 is used to adjust the first dew point temperature to be less than or equal to the second dew point temperature based on the temperature difference between the first dew point temperature and the second dew point temperature.

[0082] The control unit 706 is used to control the second dew point temperature to reach a preset dew point temperature based on the dew point adjustment parameters for controlling the second dew point temperature and the adjusted first dew point temperature.

[0083] In this embodiment of the invention, before controlling the dew point temperature of the target space, the difference between the dew point temperature of the air supplied to the target space and the current dew point temperature in the target space is determined. This allows for real-time determination of whether the dew point temperature of the air supplied to the target space is higher than the current dew point temperature in the target space, or whether there is a significant temperature difference between the two. Then, the dew point temperature of the air supplied to the target space is controlled to be less than or equal to the current dew point temperature in the target space. This not only improves the stability of the dew point temperature in the target space during the dew point temperature control process, but also reduces the energy consumption of the dehumidification system during the dew point temperature control process.
