Technical Field
[0001] This invention relates to the field of energy-saving technology, and in particular to a control method and system for a mild hybrid energy-saving dehumidifier. Background Technology
[0002] A dehumidifier is an air handling device used to reduce the moisture content in the air and maintain a specific humidity environment in a space.
[0003] In the industrial sector, rotary dehumidification systems are the mainstream dehumidifier solution. Fresh air is filtered and pre-dehumidified by a surface cooler, then mixed with return air, filtered and cooled again before entering the dehumidification rotor for deep dehumidification. After being mixed with a second batch of return air, it is pressurized by a processing fan, filtered through a medium-efficiency filter, cooled by a supply air surface cooler, and then sent to the drying workshop. The filtered fresh air is then heated to 120-130°C by a regeneration heater, regenerated by the rotor, and discharged by a regeneration fan.
[0004] Its regenerative heating requires raising the fresh air temperature from room temperature to 120 to 130°C, while cooling requires continuously cooling the air on the treatment side. Both of these have extremely high energy consumption in spring, summer, and autumn, and the cold and heat energy are not effectively utilized in synergy, resulting in low overall energy efficiency of the dehumidification system, which needs to be improved. Summary of the Invention
[0005] To improve the overall energy efficiency of dehumidification systems, this invention provides a control method and system for a mild hybrid energy-saving dehumidifier.
[0006] In a first aspect, the present invention provides a control method for a mild hybrid energy-saving dehumidifier, which adopts the following technical solution: A control method for a mild hybrid energy-saving dehumidifier includes: Collect preset information on the condensation heat of the air supply cooling system and the inlet temperature of the regenerated air; Heat recovery characteristics are extracted based on condensation heat information, and combined with inlet temperature information to determine the system thermal state; The regenerative heating mode is determined based on the system's thermal state; Collect preset outlet temperature data of the regenerative preheater; Based on the condensation heat information and outlet temperature data, determine whether the heat recovery meets the preheating requirements; When heat recovery does not meet the preheating requirements, a preset compensation heater is activated to heat the regenerated air based on the regeneration heating mode.
[0007] By adopting the above technical solution, the system first collects information on the condensation heat of the supply air cooling system and the inlet temperature of the regenerated air. Based on the condensation heat, heat recovery characteristics are extracted, and the system's thermal state is determined in conjunction with the inlet temperature, thus determining the regeneration heating mode. Next, the outlet temperature data of the regeneration preheater is collected, and combined with the condensation heat information, it is determined whether the heat recovery meets the preheating requirements. If not, the compensation heater is activated to heat the regenerated air according to the regeneration heating mode. In this way, the condensation heat generated by the supply air cooling system is recovered for preheating the regenerated air, achieving the synergistic utilization of cold and heat energy within the system. Simultaneously, the regeneration heating mode is dynamically adjusted according to the system's thermal state, and the outlet temperature data accurately determines whether heat recovery meets the standards, activating the compensation heater only when necessary, reducing additional energy consumption. This mechanism effectively reduces the overall energy consumption of the regeneration heating and cooling process, solves the problem of low cold and heat energy utilization in traditional systems, and thus improves the overall energy efficiency of the dehumidification system.
[0008] Optionally, the regenerative heating mode includes a mild hybrid energy-saving mode and a conventional heating mode, wherein the mild hybrid energy-saving mode includes: Collect supply air temperature and humidity parameters; The characteristics of the supply air cooling load are obtained based on the supply air temperature and humidity parameters. The heat recovery power is determined by combining the characteristics of the supply air cooling load and the information on condensation heat. Configure preheating parameters based on heat recovery power and inlet temperature information; The preheating operation of the preheating preheater is controlled based on the preheating parameters.
[0009] By adopting the above technical solution, in the mild hybrid energy-saving mode, the temperature and humidity parameters of the supply air are first collected to obtain the supply air cooling load characteristics. These characteristics, combined with condensation heat information, determine the heat recovery power. Then, based on the heat recovery power and the regenerated air inlet temperature, preheating parameters are configured. Finally, the regenerated preheater is controlled to perform preheating operations based on these preheating parameters. This heating mode, which primarily recovers waste heat, minimizes the additional energy consumption of regenerated heating, fully leverages the advantages of mild hybrid energy saving, and further improves the energy efficiency ratio of the dehumidification system.
[0010] Optionally, the conventional heating mode includes: Collect available state parameters of high-grade heat sources and target air temperature of regenerated air; The temperature difference is obtained by matching the preset regeneration temperature value with the system thermal state. The compensation heating amount is matched based on the temperature difference; Based on available state parameters and compensation heating amount, generate compensation heating command; In response to a compensation heating command, a preset compensation heater is controlled to heat the preheated regenerated air until the target air temperature is reached.
[0011] By adopting the above technical solution, in the traditional heating mode, the available state parameters of the high-grade heat source and the target temperature of the regenerated air are first collected. The regenerated temperature value is matched from the system thermal state to calculate the temperature difference. Based on the temperature difference, the required compensation heating amount is determined. Then, combined with the available state parameters of the high-grade heat source, a compensation heating command is generated. Finally, in response to the command, the compensation heater is controlled to heat the preheated regenerated air to the target temperature. This mode, as a supplement to the mild hybrid energy-saving mode, can maintain system performance under extreme operating conditions while reducing unnecessary energy consumption through quantitative control, achieving a balance between energy efficiency and reliability.
[0012] Optional, also includes: Collect the temperature of the supplied air; The supply air temperature difference is determined based on the supply air temperature and the preset target supply air temperature. Determine whether the supply air temperature difference exceeds the preset temperature difference threshold; When the supply air temperature difference exceeds the temperature difference threshold, the preset precooler is activated to absorb the heat of the supply air. When the supply air temperature difference does not exceed the temperature difference threshold, the preset precooler is kept off.
[0013] By adopting the above technical solution, the temperature of the supplied air is first collected, and the difference between it and the preset target supplied air temperature is calculated. It is then determined whether this difference exceeds a temperature difference threshold. If it does, the precooler is activated to absorb heat from the supplied air; otherwise, the precooler remains closed. This reduces the additional energy consumption in the refrigeration process and, in conjunction with the regenerative heating heat recovery mechanism, optimizes the overall energy efficiency of the dehumidification system.
[0014] Optional, also includes: Collect humidity information for the preset dehumidification area; Determine humidity distribution characteristics based on regional humidity information; Determine the area with the highest humidity based on humidity distribution characteristics; The dehumidifier is controlled to perform dehumidification of the area with the highest humidity using a preset cycle dehumidification method.
[0015] By adopting the above technical solution, the humidity information of the dehumidification area is first collected, the humidity distribution characteristics are analyzed and the area with the highest humidity is determined, and then the dehumidifier is controlled to dehumidify the area in a targeted manner using a turnover dehumidification method. This improves the dehumidification efficiency, shortens the time for the system to reach the target humidity, and further optimizes the energy efficiency performance of the dehumidification system.
[0016] Optionally, the turnover dehumidification method includes: Determine the initial dehumidification range based on the area with the highest humidity; The turnover dehumidification path is obtained based on the initial dehumidification range; Control the dehumidifier to circulate air according to the circulation dehumidification path, and collect real-time humidity distribution data during the circulation air circulation process; Combine real-time humidity distribution data and turnover dehumidification path to generate dynamic dehumidification range; The system updates the turnover dehumidification path based on the dynamic dehumidification range and controls the dehumidifier to perform precise zone dehumidification based on the updated turnover dehumidification path.
[0017] By adopting the above technical solution, an initial dehumidification range is first determined based on the area with the highest humidity, and a revolving dehumidification path is planned. The dehumidifier is then controlled to circulate and deliver air along this path. During the air delivery process, real-time humidity distribution data is collected, and combined with this data and the original path to generate a dynamic dehumidification range. This process then updates the revolving path, achieving precise regional dehumidification. This approach overcomes the limitations of fixed-range dehumidification by dynamically adjusting the dehumidification range and path based on real-time humidity data. Simultaneously, this dynamic adjustment ensures that dehumidification resources are always focused on the areas most in need of dehumidification, reducing unnecessary energy consumption in low-humidity areas. This adaptive revolving strategy significantly improves energy utilization efficiency while maintaining dehumidification effectiveness.
[0018] Optional, also includes: Collect regional image information of the dehumidification area; Obstacle distribution information is obtained by identifying regional image information; Obstacle contour features are determined based on obstacle distribution information; The obstacle avoidance and dehumidification path is generated by combining obstacle outline features and real-time humidity distribution data. Optimal air supply parameters are calculated based on the obstacle avoidance and dehumidification path. The dehumidifier is controlled to dehumidify according to the obstacle avoidance dehumidification path, while the air supply direction and air supply intensity are adjusted based on the optimal air supply parameters.
[0019] By adopting the above technical solution, image information of the dehumidification area is first collected to identify the distribution and contour features of obstacles. This information is then combined with real-time humidity distribution data to generate an obstacle-avoidance dehumidification path. Next, optimal air supply parameters are calculated based on the path, controlling the dehumidifier to dehumidify along the obstacle-avoidance path, and adjusting the air supply direction and intensity according to the parameters. This approach solves the problem of obstacles obstructing the dehumidification airflow. By identifying obstacle contours and planning obstacle-avoidance paths, it avoids localized dehumidification ineffectiveness caused by blocked dehumidification airflow. Simultaneously, the optimal air supply parameters ensure that the dehumidification airflow efficiently reaches high-humidity areas, reducing energy waste caused by airflow obstruction.
[0020] Optional, also includes: Collect current environmental wind parameters; The environmental wind influencing factor is calculated based on environmental wind parameters and obstacle avoidance and dehumidification paths. The optimal air supply parameters are adjusted based on environmental wind influencing factors. Adjust the air supply direction and intensity based on the corrected optimal air supply parameters.
[0021] Optional, also includes: The control parameters for the air guide plate are generated based on the obstacle avoidance and dehumidification path and the outline features of the obstacles. The air guide plate, which is pre-set on the dehumidifier, is deployed based on the control parameters of the air guide plate. Collect ambient wind force, ambient wind direction, and ambient wind turbulence intensity; The control parameters of the wind deflector are corrected by combining the ambient wind force, ambient wind direction, ambient wind turbulence intensity, and wind deflector control parameters. Adjust the deployment angle and deflection direction of the air guide plate based on the revised control parameters.
[0022] By adopting the above technical solution, the control parameters for the air guide plate are first generated based on the obstacle avoidance and dehumidification path and the outline characteristics of the obstacle, and the deployment of the air guide plate is controlled. Then, the wind force, wind direction, and turbulence intensity of the ambient wind are collected, and these environmental factors are combined with the initial air guide plate control parameters for correction. Finally, the deployment angle and deflection direction of the air guide plate are adjusted based on the corrected parameters. This dual control ensures that the dehumidified airflow is always delivered to the target area efficiently, reducing ineffective energy consumption caused by airflow turbulence or obstruction, and further improving the energy efficiency and dehumidification accuracy of the dehumidification system.
[0023] Secondly, this application provides a mild hybrid energy-saving dehumidifier control system, which adopts the following technical solution: A mild hybrid energy-saving dehumidifier control system includes: The data acquisition module is used to collect information on condensation heat, inlet temperature, and outlet temperature. A memory for storing a program that implements a mild hybrid energy-saving dehumidifier control method; The processor is used to load and execute programs stored in memory.
[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By recovering the condensation heat generated by the air supply cooling system and using it to preheat the regenerated air, the system achieves synergistic utilization of cold and heat energy. Simultaneously, the regeneration heating mode is dynamically adjusted based on the system's thermal state, and the heat recovery is precisely assessed using outlet temperature data. The compensation heater is activated only when necessary, reducing additional energy consumption. This mechanism effectively reduces the overall energy consumption of the regeneration heating and cooling processes, solving the problem of low cold and heat energy utilization in traditional systems, thereby improving the overall energy efficiency of the dehumidification system. 2. In mild hybrid energy-saving mode, the temperature and humidity parameters of the supply air are first collected to obtain the supply air cooling load characteristics. These characteristics, combined with condensation heat information, determine the heat recovery power. Then, based on the heat recovery power and the regenerated air inlet temperature, preheating parameters are configured. Finally, the regenerated preheater is controlled to perform preheating operations based on these preheating parameters. This heating mode, which primarily recovers waste heat, minimizes the additional energy consumption of regenerated heating, fully leverages the advantages of mild hybrid energy saving, and further improves the energy efficiency ratio of the dehumidification system. 3. The dehumidification range and path are dynamically adjusted based on real-time humidity data. At the same time, the dynamic adjustment ensures that dehumidification resources are always focused on the areas that need the most dehumidification, reducing unnecessary energy consumption in low-humidity areas. This significantly improves energy utilization efficiency while ensuring dehumidification effect. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0028] Reference Figure 1 , 2 3 and 4, embodiments of this application disclose a control method for a mild hybrid energy-saving dehumidifier. This method is applied to a mild hybrid energy-saving dehumidifier, wherein the regenerative heating of the mild hybrid energy-saving dehumidifier is divided into two parts. One part of the heating energy is provided by traditional high-quality heat sources such as electricity, steam, and thermal oil. The other part is regenerated by transferring the heat energy generated by the air supply cooling. In spring and autumn, the heat energy generated by the air supply cooling is mainly used as the regenerative heating energy. In summer, the heating from spring and autumn is supplemented by traditional high-quality heat sources such as electricity, steam, and thermal oil to reach 120 to 130°C. In the mild hybrid energy-saving dehumidifier, the air supply cooling is divided into two to three parts for cooling, as specifically implemented as follows: In this embodiment, the first part of the air supply cooling is achieved through the coordinated heat transfer and cooling of precooler 2# and regeneration preheater 1#. Specifically, precooler 2# is connected to the air supply path and absorbs heat from the air supply through heat exchange, effectively reducing the air supply temperature and thus reducing the load on subsequent cooling stages. Simultaneously, precooler 2# forms a closed-loop fluid circulation system with the compressor pump and regeneration preheater 1# via connecting pipes. The compressor pump, as a power source, drives the flow of heat transfer fluid (such as refrigerant like Freon) inside the connecting pipes, transferring the heat absorbed by precooler 2# to regeneration preheater 1#. Regeneration preheater 1# is connected to the regeneration fresh air path and releases heat as the heat transfer fluid flows through it, raising the temperature of the regeneration fresh air to 50-55°C after absorbing heat, laying the foundation for subsequent regeneration heating.
[0029] In addition, a storage tank and a separator are connected in series on the connecting pipe: the storage tank stores excess energy in the connecting pipe and can release or store energy when environmental conditions (such as fluctuations in supply air temperature and changes in regenerated fresh air volume) change, ensuring the stability of system operation; the separator separates the gaseous and liquid mixtures in the fluid in the connecting pipe, retaining only the liquid fluid to continue participating in the circulation, avoiding the gaseous fluid from affecting heat transfer efficiency. A mechanical shut-off valve is also installed on the side of the connecting pipe near the precooler 2#. This mechanical shut-off valve is used to cut off and reduce the pressure of the high-pressure liquid in the connecting pipe. Its opening degree is automatically controlled by a temperature sensor. The temperature sensor detects the temperature of the liquid in the connecting pipe after absorbing heat and transfers the corresponding heat to the inside of the shut-off valve. The expansion or contraction of the internal medium (such as the liquid in the temperature sensing bulb) pushes the valve needle to open or close, thereby adjusting the opening degree. In this embodiment, the mechanical shut-off valve is designed according to a standard superheat of 5K. When the superheat is less than 5K, it indicates that the fluid vaporization is insufficient, and the opening of the shut-off valve needs to be reduced to reduce the fluid flow rate and avoid wasting cooling capacity. When the superheat is greater than 5K, it indicates that the fluid vaporization is excessive, and the opening of the shut-off valve needs to be increased to increase the fluid flow rate and ensure refrigeration efficiency.
[0030] The second part of the air supply cooling system achieves deep heat recovery and cooling through the synergy of precooler 1# and regenerative preheater 2#. Precooler 1#, located downstream of precooler 2# in the air supply path, further absorbs residual heat from the supply air, continuously reducing the supply air temperature to meet the drying workshop's requirements for supply air temperature (typically below 16℃). Precooler 1# also forms a closed-loop circulation with another set of compressor pumps and regenerative preheater 2# via connecting pipes. The compressor pump drives the heat transfer fluid to transfer the heat absorbed by precooler 1# to regenerative preheater 2#. Regenerative preheater 2#, located downstream of regenerative fresh air in the fresh air path, has already been heated to 50-55℃ by regenerative preheater 1#. The heat released by regenerative preheater 2# is further absorbed by the fresh air, raising its temperature again to 80-85℃, significantly reducing the compensation heating load of subsequent high-grade heat sources. The connecting pipes of this circulation loop are also equipped with a storage tank and a separator, whose functions are the same as those of the storage tank and separator corresponding to the precooler #2 mentioned above, used for energy buffering and gas-liquid separation, respectively. Furthermore, this loop uses an electronic shut-off valve instead of a mechanical shut-off valve. The opening of the electronic shut-off valve is automatically adjusted by a dedicated controller: the controller presets a superheat threshold of 4 to 6K (preferably 5K in this embodiment), detects the actual temperature of the liquid after vaporization in the connecting pipe after heat absorption using a temperature sensor, and detects the saturation pressure of the liquid after vaporization in this state using a pressure sensor, feeding back the two real-time signals of temperature and pressure to the controller; the controller calculates the adjustment command based on the difference between the preset superheat and the actual superheat, generating a pulse signal to control the opening of the electronic shut-off valve—when the superheat is less than 5K, the opening is reduced to decrease the fluid flow rate; when the superheat is greater than 5K, the opening is increased to increase the fluid flow rate, achieving more precise control of cooling capacity and heat transfer.
[0031] exist Figure 4 In the system shown in the (process flow diagram of the light-mix energy-saving dehumidifier), the fresh air cooling and return air cooling of the light-mix energy-saving dehumidifier can use chilled water as the cooling source or Freon direct cooling as the cooling source. The specific cooling source type can be selected according to the user's site conditions and cost requirements. Whether or not to set up return air cooling and return air filtration can be determined according to the user's process requirements for air drying (such as the cleanliness and humidity accuracy of the drying workshop). For the supply air cooling stage, it is necessary to determine whether to add supply air cooling based on the actual cooling load of the supply air cooling: if the supply air temperature can be stably reduced to below 16℃ by the synergistic cooling of the precooler 1# and precooler 2#, then there is no need to set up additional supply air cooling; if the supply air temperature requirements still cannot be met, a supply air cooling needs to be added downstream of precooler 1# to supplement the cooling capacity and ensure that the supply air parameters meet the usage requirements of the drying workshop.

[0058] S15: When heat recovery does not meet the preheating requirements, the pre-set compensation heater is activated to heat the regenerated air based on the regeneration heating mode.
[0059] A compensating heater is a device that uses a high-grade heat source to supplement the heating of regenerated air.
[0060] When heat recovery fails to meet preheating requirements, it means that the recovered condensation heat alone is insufficient to bring the regenerated air to the target preheating temperature. In this case, it is necessary to start the compensation heater to supplement the insufficient heat in order to heat the regenerated air.
[0061] The heating modes include mild hybrid energy-saving mode and traditional heating mode. The mild hybrid energy-saving mode includes: S20: Collect supply air temperature and humidity parameters.
