[0080] Background

[0081] In traditional industrial production systems, the design of air-conditioning systems and production workshops is often separated, and there is a lack of direct and in-depth interaction between the two, which makes it difficult for the air-conditioning system to cope with the personalized temperature and humidity requirements and air quality changes in each work area of ​​the production workshop, which in turn causes a series of problems. First, this separate design makes it difficult for the air-conditioning system to take into account the complexity of local heat distribution in the production workshop and the differences in heat loads at workstations when adjusting the overall environment, resulting in excessive or insufficient energy supply, inefficient resource allocation, and failure to meet the high requirements of environmental control.

[0082] Based on this, Figure 1-Figure 2 As shown, the first aspect of the embodiment of the present application provides an air conditioning system, including:

[0083] A main heat exchange path, on which a compressor 100 and a condenser 200 are provided, which are sequentially connected via a refrigerant pipeline; and

[0084] Multiple heat exchange branches, multiple heat exchange branches are connected in parallel to the heat exchange main circuit and are located between the suction side of the compressor and the liquid outlet side of the condenser, each heat exchange branch is equipped with an independent heat exchange unit, and each heat exchange unit corresponds to a working interval 300;

[0085] The heat exchange unit includes an evaporator 400 and a flow regulating component 500 connected through a refrigeration pipeline on the heat exchange branch, and an air supply fan 600 for conveying the airflow after heat exchange with the evaporator of the heat exchange unit to the corresponding working area 300;

[0086] The control device is configured to: adjust the flow regulating component and / or the fan of the corresponding working interval accordingly according to the air conditioning needs of each working interval.

[0087] The air conditioning system provided in the embodiment of the present application can realize accurate cooling or heating of each working interval by setting up multiple parallel heat exchange branches, and each heat exchange branch is equipped with an independent heat exchange unit, and each heat exchange unit corresponds to a working interval, thereby avoiding the energy waste problem that may exist in traditional centralized air conditioning systems and meeting the high requirements of environmental control. Specifically, by obtaining the air conditioning needs of each working interval, the flow regulating components and / or fans of the corresponding working interval can be adjusted accordingly to realize accurate cooling or heating of each working interval.

[0088] Further, in some possible implementations, the refrigerant liquid inlet side of the evaporator 400 is provided with a solenoid valve 501 and an electronic expansion valve 502 as a flow regulating component 500, and the refrigerant gas outlet side of the evaporator 400 is connected to the suction side of the compressor 100 in the heat exchange main circuit;

[0089] The control device is configured to: adjust the opening and closing of the solenoid valve according to whether each working interval needs air supply, and / or adjust the opening of the electronic expansion valve according to the air supply temperature required by each working interval, and / or adjust the speed of the air supply fan according to the air supply volume required by each working interval.

[0090] That is, the above-mentioned working interval needs refer to whether the working interval needs air supply, and / or the air supply temperature required by the working interval when air is supplied to the working interval, and / or the air supply volume and / or air supply speed required by the working interval when air is supplied to the working interval.

[0091] In the embodiment of the present application, by setting the solenoid valve 501 and the electronic expansion valve 502 as the flow regulating component 500, the system can accurately control the refrigerant flow rate and / or flow rate in the corresponding heat exchange branch and the air supply speed and / or air supply volume of the air supply fan according to the specific needs of each working interval, thereby achieving an accurate air supply effect. This precise control helps to achieve accurate regulation of the temperature of each working interval and meet the specific needs of different working intervals. Specifically, the solenoid valve 501 is used to control the on and off of the heat exchange branch and the main heat exchange path, which means that the system can flexibly open or close specific heat exchange branches according to the actual needs of the working interval, thereby achieving a reasonable allocation and conservation of energy. By controlling the flow parameters of the refrigerant through the electronic expansion valve 502, the system can dynamically adjust the refrigerant flow according to the changes in the heat load of the working interval, optimize energy distribution, and improve energy utilization efficiency.

[0092] That is, in the embodiment of the present application, the refrigerant flow is precisely controlled, the system start and stop control is flexible, the energy distribution is optimized, the system response speed is improved, the reliability and stability of the system are enhanced, different working conditions are adapted, and energy consumption and operation and maintenance costs are reduced. These technical effects work together to enable the air conditioning system to serve different working intervals more efficiently and flexibly, thereby improving the overall energy utilization efficiency and system performance.

[0093] Furthermore, in some possible implementations, the main heat exchange circuit is further provided with a liquid storage tank 700 and a distribution station 800 which are sequentially connected through a refrigerant pipeline;

[0094] The inlet of the liquid storage tank 700 is connected to the liquid outlet side of the condenser 200, the outlet of the liquid storage tank 700 is connected to the inlet of the distribution station 800, and the outlet of the distribution station 800 is connected to a plurality of heat exchange branches arranged in parallel.

[0095] In the embodiment of the present application, by setting up a liquid storage tank 700 and a distribution station 800, the system can store and distribute refrigerant. The liquid storage tank can store excess refrigerant for use when the system load changes, while the distribution station is responsible for evenly distributing the refrigerant to each heat exchange branch to ensure stable operation of the system. The distribution station 800 distributes the refrigerant in the liquid storage tank to multiple heat exchange branches arranged in parallel, allowing the system to dynamically adjust the flow direction and flow rate of the refrigerant according to the specific needs of each working interval, thereby improving the flexibility and adjustment ability of the system.

[0096] Further, in some possible implementations, the air conditioning system further includes an air inlet 301 and an air outlet 302 disposed in each working interval, a heat exchange unit is disposed between the air inlet 301 and the air outlet 302, an evaporator 400 in the heat exchange unit is used to perform heat exchange processing on the airflow in the working interval 300, and an air supply fan 600 is used to discharge the airflow after heat exchange from the air outlet 302;

[0097] Each working area 300 of the air conditioning system is also provided with an air auxiliary processing module 900 between the evaporator 400 and the air inlet 301, and the air auxiliary processing module 900 is used to purify the airflow before passing through the evaporator 400;

[0098] The control device is further configured to adjust the air purification intensity of the air auxiliary processing module according to the air quality level of each working interval.

[0099] In the embodiment of the present application, an independent heat exchange unit is provided in each working interval 300 of the air-conditioning system, which means that each area can perform personalized temperature control and air purification according to its specific needs, thereby improving comfort and production efficiency. By configuring an independent heat exchange unit for each working interval, the system can more accurately control the energy consumption of each area, reduce unnecessary energy waste, and improve overall energy utilization efficiency. Independently controlled heat exchange units allow the system to be adjusted according to the specific needs of each working interval, thereby enhancing the system's adaptability to different environments and working conditions. In addition, since each working interval has an independent heat exchange unit, the system can more flexibly respond to changes in temperature and air quality in different areas and achieve better environmental control. At the same time, the design of independent heat exchange units can also make system maintenance and troubleshooting more convenient, and maintenance can be performed on specific areas without affecting the normal operation of other areas, thereby reducing operation and maintenance costs.

[0100] In addition, the evaporator 400 in the heat exchange unit in the embodiment of the present application is located between the air inlet 301 and the air outlet 302, which can effectively perform heat exchange treatment on the airflow entering the working interval 300, ensuring that the airflow reaches the required temperature before entering the working interval. The air auxiliary processing module 900 arranged between the evaporator 400 and the air inlet 301 can purify the airflow. This design can effectively remove harmful substances and particles in the air, improve the quality of air entering the working interval, and protect the health of the staff. Specifically, by adjusting the purification intensity of the air by the air auxiliary processing module according to the air quality level of the working interval, targeted purification of the air in the working interval can be achieved.

[0101] That is, in the embodiment of the present application, by combining the air auxiliary processing module 900 with the evaporator 400, the system can ensure the cleanliness of the air while adjusting the temperature, thereby improving the overall environmental control performance. At the same time, by purifying the airflow before it passes through the evaporator 400, the accumulation of pollutants in the evaporator can be reduced, maintaining its efficient operation, and further optimizing the energy efficiency of the system. The airflow that has undergone heat exchange and purification will be discharged by the air supply fan 600, providing a comfortable working environment. Good air quality and suitable temperature can improve the work satisfaction and comfort of employees.

[0102] Further, in some possible implementations, the air-assisted processing module 900 includes at least one of an electrostatic dust removal module 901, a filter module 902, and a catalytic oxidation module 903. Preferably, the air-assisted processing module 900 includes an electrostatic dust removal module 901, a filter module 902, and a catalytic oxidation module 903.

[0103] The air-assisted treatment module 900 in the embodiment of the present application includes at least one of an electrostatic dust removal module 901, a filtration module 902 and a catalytic oxidation module 903, which means that the system can provide a comprehensive purification solution for different types of air pollutants. Specifically, the electrostatic dust removal module 901 can effectively remove fine particles in the air, which is particularly important for particulate pollutants such as dust and smoke that are common in industrial environments. The filtration module 902 further removes fine particles in the air, provides a deeper level of purification, and ensures that the air quality reaches higher standards. The catalytic oxidation module 903 can process harmful gases in the air and convert harmful gases into harmless substances through catalytic reactions, which is crucial to improving air quality and protecting employee health. Through the setting of at least one air-assisted treatment module, the system can significantly improve the air quality in the working area 300 and reduce the potential impact on employee health and production processes.

[0104] Furthermore, in some possible implementations, the electrostatic dust removal module 901 , the filtration module 902 , and the catalytic oxidation module 903 are sequentially arranged from the air inlet 301 side to the air outlet 302 side.

[0105] In the embodiment of the present application, the electrostatic dust removal module 901, the filtering module 902 and the catalytic oxidation module 903 are arranged in sequence, ensuring that the airflow first passes through the electrostatic dust removal module to remove particulate matter before entering the working area 300, then passes through the filtering module to further remove fine particles, and finally the catalytic oxidation module processes harmful gases. This sequential arrangement improves the efficiency and effect of air purification.

[0106] It is worth noting that if the catalytic oxidation module and the electrostatic precipitator module are interchanged, solid pollutants will enter the catalytic oxidation device, which will affect the decontamination capacity. In the embodiment of the present application, the electrostatic precipitator module 901, the filtration module 902 and the catalytic oxidation module 903 are arranged in sequence to maximize their decontamination capacity.

[0107] Further, in some possible implementations, the electrostatic precipitator module 901 includes a dust collecting electrode plate and a discharge motor plate integrated together;

[0108] The filter module 902 includes a filter with an activated carbon sandwich;

[0109] The catalytic oxidation module 903 includes a catalytic oxidation device having a heating device.

[0110] The electrostatic dust removal module 901 in the embodiment of the present application integrates a dust collecting electrode plate and a discharge electrode plate. This integrated design can improve the dust removal efficiency, because the corona effect generated by the discharge electrode plate can make the particulate debris in the air acquire an electric charge, and then be adsorbed by the dust collecting electrode plate, effectively removing fine particles in the air. The filter interlayer in the filter module 902 is provided with activated carbon. This design can not only remove fine particles in the air, but also use the adsorption characteristics of activated carbon to remove harmful gases and odors, providing a deeper level of air purification. The catalytic oxidation module 903 includes a catalytic oxidation device with a heating device. This design can activate the catalyst and improve the oxidation conversion efficiency of harmful gases, especially when dealing with volatile organic compounds VOCs and other harmful gases. By integrating these three modules together, a coherent air purification process is formed, so that the air can be sequentially treated with dust removal, filtration and catalytic oxidation before entering the working area to ensure air quality.

[0111] It is worth noting that the heating device can adjust the temperature as needed and only provide enough heat to activate the catalyst when necessary, which can reduce unnecessary energy consumption and improve the energy efficiency of the system.

[0112] Furthermore, in some possible implementations, a sensor module is also integrated in each working interval 300 of the air conditioning system;

[0113] The sensor module is used to obtain the environmental cleanliness parameters in the corresponding working interval 300, and the control device is used to adjust the purification intensity of the air by the air auxiliary processing module in the corresponding working interval 300 according to the environmental cleanliness parameters;

[0114] The environmental cleanliness parameter includes at least one of the number of particles in the air and the concentration of harmful gases in the air.

[0115] In the embodiment of the present application, the sensor module integrated in each working interval 300 can obtain environmental cleanliness parameters in real time, including the number of particulate matter and the concentration of harmful gases, which enables the system to respond quickly to environmental changes and adjust the air purification intensity in time. The integration of the sensor module realizes the intelligent control of air purification. The system can automatically adjust the working state of the air auxiliary processing module according to real-time data to improve the efficiency and effect of air purification. By intelligently adjusting the air purification intensity, the system can reduce energy consumption when high-intensity purification is not required, thereby improving energy efficiency and reducing operating costs. The system can adapt to the purification needs of different working intervals according to specific environmental cleanliness parameters, and both particulate matter and harmful gases can be effectively controlled.

[0116] Further, in some possible implementations, the sensor module is further used to obtain personnel information in the corresponding working area, and the control device is used to control whether the heat exchange unit in the corresponding working area is running according to the personnel information, wherein the personnel information includes whether there is a person in the corresponding area;

[0117] The sensor module is also used to obtain the ambient temperature in the corresponding area, and the control device is also used to adjust the air outlet temperature of the air outlet according to the ambient temperature.

[0118] The sensor module in the embodiment of the present application obtains personnel information and controls the operation of the heat exchange unit according to whether there are personnel, thereby realizing automatic control based on the presence of personnel, thereby automatically shutting down the heat exchange unit when no one is around, saving energy. By obtaining the ambient temperature and adjusting the air outlet temperature of the air outlet accordingly, the system can provide a more comfortable environment, especially when there are personnel, ensuring that the temperature meets the comfort needs of the human body.

[0119] That is, the sensor module in the embodiment of the present application enables the system to respond quickly according to real-time environmental changes. Whether it is the flow of personnel or temperature changes, the system can adjust in time to provide appropriate environmental control.

[0120] Further, in some possible implementations, the sensor module includes a charge induction sensor 10, an electrochemical sensor 1 20, an optical particle sensor 30, an electrochemical sensor 2 40, and an infrared thermal imaging sensor 50;

[0121] The charge sensing sensor 10 and the electrochemical sensor 20 are arranged at the front end of the filter module 902 to detect the airflow flowing through the filter module 902. The optical particle sensor 30 and the electrochemical sensor 2 40 are arranged at the rear end of the catalytic oxidation module 903 to detect the airflow flowing through the catalytic oxidation module 903. The infrared thermal imaging sensor 50 is used to obtain the temperature value in the corresponding working interval 300 and detect whether there is a person in the corresponding working interval 300.

[0122] In the embodiment of the present application, by using multiple types of sensors, the system can accurately monitor the number of particles in the air, the concentration of harmful gases and the temperature, and provide comprehensive air environment data. Among them, the charge sensing sensor 10 and the electrochemical sensor 1 20 are detected at the front end of the filter module 902, and the optical particle sensor 30 and the electrochemical sensor 2 40 are detected at the rear end of the catalytic oxidation module 903. Such a layout can provide real-time feedback on the air purification effect to ensure that the air quality meets the standard. The infrared thermal imaging sensor 50 detects the presence of personnel. Combined with the temperature data, the system can adjust the temperature and air purification intensity according to the actual needs of the personnel to avoid energy waste when no one is around. By accurately monitoring the air quality and temperature, the system can make timely adjustments to reduce the impact of harmful gases and particulate matter on personnel health and improve the safety of the workplace.

[0123] Further, in some possible implementations, the multiple work areas 300 are multiple production stations in a production workshop;

[0124] The production station has a workbench, the interior of which accommodates an evaporator 400 and an air supply fan 600, and a grid-shaped workbench surface 303 is formed on the top;

[0125] The air inlet 301 and the air outlet 302 are arranged vertically and distributedly, and the air inlet 301 is located below the work surface 303 .

[0126] That is, it is preferred in the embodiment of the present application that the multiple working intervals 300 are multiple production stations in the production workshop. This design closely combines the air conditioning system with the production station, thereby improving the space utilization and system integration. The evaporator 400 and the air supply fan 600 are built into the workbench, and the top is a grid-shaped workbench 303, so that the airflow can directly perform precise temperature control and air purification on the working interval. In addition, the air inlet 301 and the air outlet 302 are arranged in an upper and lower distribution, and the air inlet is located below the workbench, which is conducive to collecting fine particles and harmful gases generated during the work process, while reducing direct blowing to the workers and optimizing the working environment. By arranging the air inlet below the workbench, the air that may contain harmful gases and particulates such as welding fumes, volatile organic compounds, and metal dust can be more effectively inhaled, and then discharged from the air outlet after purification, thereby improving the air quality.

[0127] It is worth mentioning that the work surface is configured as a mesh structure to facilitate the absorption of debris and harmful gases generated during the production process into the purification device below.

[0128] Furthermore, in some possible implementations, a partition 60 is formed between the multiple production stations, and the partition 60 is used to separate two adjacent production stations.

[0129] In the embodiment of the present application, by setting a separator 60 to separate adjacent production stations, the independence of each station can be enhanced, so that each station can independently control environmental conditions, such as temperature and air quality, without being affected by adjacent stations. In addition, the separators 60 help to improve the accuracy of environmental control, because they can prevent hot and cold air or purified air from flowing disorderly between different stations, thereby ensuring that the environmental control of each station is more accurate. Since each station can independently control environmental conditions, it can be optimized according to the specific production needs of different stations, thereby improving the overall production efficiency. In addition, during the production process, the separator 60 can reduce cross contamination between different stations, which is particularly important in production lines that process different materials or chemicals. At the same time, by setting the separator 60, the energy exchange between adjacent stations can be reduced, energy loss can be reduced, and energy utilization efficiency can be improved.

[0130] Furthermore, the second aspect of the embodiment of the present application further provides a control method, which is applied to the air conditioning system provided in the first aspect of the embodiment of the present application, wherein the control method includes:

[0131] According to the air conditioning needs of each working area, the flow regulating components and / or fans of the corresponding working areas are adjusted accordingly.

[0132] Further, according to the air conditioning needs of each working area, the flow regulating component and / or the fan of the corresponding working area is adjusted accordingly, including:

[0133] The opening and closing of the solenoid valve is adjusted according to whether each working interval needs air supply, and / or the opening of the electronic expansion valve is adjusted according to the air supply temperature required by each working interval, and / or the speed of the air supply fan is adjusted according to the air supply volume required by each working interval.

[0134] Furthermore, in some possible implementations, the above control method further includes:

[0135] Acquire environmental cleanliness parameters within the working area, and adjust the air purification intensity of the air auxiliary processing module within the working area according to the environmental cleanliness parameters;

[0136] The environmental cleanliness parameter includes at least one of the number of particulate matter in the air and the concentration of harmful gases in the air, and the air auxiliary processing module includes an electrostatic dust removal module, a filtration module and a catalytic oxidation module.

[0137] In the embodiment of the present application, intelligent environmental management is achieved by automatically acquiring environmental cleanliness parameters and adjusting the purification intensity of the air-assisted treatment module according to these parameters, thereby reducing the need for manual intervention.

[0138] Furthermore, in some possible implementations, adjusting the purification intensity of the air by the air auxiliary processing module in the working area according to the environmental cleanliness parameter includes:

[0139] If the number of particles in the working area exceeds the preset number of particles, increasing the discharge amount of the discharge electrode plate in the electrostatic precipitator module; and / or

[0140] If the concentration of harmful gases in the working area exceeds a preset concentration, the heating temperature of the heating device in the catalytic oxidation module is increased.

[0141] In the embodiment of the present application, the system can dynamically adjust the purification efficiency according to the actual environmental cleanliness parameters, ensuring a rapid response when the concentration of particulate matter or harmful gases exceeds the standard, thereby improving the purification effect. By accurately controlling the discharge amount of the electrostatic precipitator module and the heating temperature of the catalytic oxidation module, the system can more accurately process pollutants in the air and improve the purification accuracy. And the system only increases the purification intensity when it detects that the air quality exceeds the standard, avoiding unnecessary energy waste and improving energy utilization efficiency. By reasonably controlling the discharge amount and heating temperature, the equipment can be prevented from running at high intensity for a long time, reducing equipment loss and extending equipment life.

[0142] Furthermore, in some possible implementations, the control method further includes:

[0143] While increasing the discharge amount of the discharge electrode plates in the electrostatic precipitator module, adjusting the operating parameters of the air supply fan to reduce the air supply speed, and / or

[0144] While increasing the heating temperature of the heating device in the catalytic oxidation module, the operating parameters of the air supply fan are adjusted to reduce the air supply speed.

[0145] In the embodiment of the present application, by increasing the discharge amount of the discharge electrode plate or the heating temperature of the heating device while reducing the air supply speed, the residence time of the airflow in the electrostatic dust removal module and the catalytic oxidation module can be increased, thereby improving the purification efficiency. Reducing the air supply speed can reduce the interference of the airflow on the purification module, so that particulate matter and harmful gases in the air have more time to be processed, and optimize the air flow and purification process. At the same time, appropriately reducing the air supply speed can reduce the energy consumption of the fan without sacrificing the purification effect, and improve the energy efficiency of the entire system. At the same time, reducing the air supply speed can reduce the secondary lifting of particulate matter during the purification process, reducing the risk of re-contamination of the purified air.

[0146] Further, in some possible implementations, if the number of particles in the working area exceeds a preset number of particles, increasing the discharge amount of the discharge electrode plate in the electrostatic precipitator module includes:

[0147] If the number of particles in the working area exceeds the preset number of particles within the preset time, an alarm message is output;

[0148] and / or

[0149] If the concentration of harmful gases in the working area exceeds a preset concentration, increasing the heating temperature of the heating device in the catalytic oxidation module includes:

[0150] If the concentration of harmful gases in the working area still exceeds the preset concentration within the preset time, an alarm message will be output.

[0151] In the embodiment of the present application, by continuously monitoring the number of particulate matter and the concentration of harmful gases, the system can grasp the environmental conditions in real time and detect potential environmental problems in a timely manner. At the same time, when the particulate matter or harmful gases exceed the preset threshold, the system will not only increase the purification intensity, but also output an alarm message if there is no improvement after the preset time, ensuring that the problem can be handled in a timely manner. Alarm information helps prevent health risks and safety accidents caused by environmental problems, especially in industrial environments, which is crucial to protecting the health and safety of employees.

[0152] That is, in the embodiment of the present application, the system can automatically adjust the purification intensity according to environmental changes and issue an alarm when necessary, thereby improving the adaptability and flexibility to different environmental conditions.

[0153] Furthermore, in some possible implementations, the control method further includes:

[0154] Obtaining personnel information in the working area, if it is detected that there is a person in the working area, controlling the heat exchange unit in the working area to operate, if it is detected that there is no person in the working area, controlling the heat exchange unit in the working area to stop operating; and / or

[0155] The actual temperature value of the working range is obtained, the actual temperature value is compared with the preset temperature value, and the air outlet temperature of the air outlet is adjusted based on the comparison result of the actual temperature value and the preset temperature value.

[0156] In the embodiment of the present application, by obtaining the personnel information in the working area and controlling the operation of the heat exchange unit accordingly, the system can automatically shut down the heat exchange unit when no one is present, saving energy consumption and achieving automated energy saving. The system automatically adjusts the heat exchange unit according to the presence of personnel to ensure that a suitable temperature is provided when someone is present, thereby improving the comfort and work efficiency of the staff. In addition, by combining the acquisition of personnel information and actual temperature values, the system can achieve more intelligent environmental control and automatically adjust to adapt to environmental changes and personnel needs. The system can flexibly respond to personnel flow and temperature changes, and quickly adjust the heat exchange unit and outlet air temperature to maintain environmental stability and comfort.

[0157] Further, in some possible implementations, adjusting the air outlet temperature of the air outlet based on the comparison result between the actual temperature value and the preset temperature value includes:

[0158] If the actual temperature value exceeds the preset temperature value, the opening of the electronic expansion valve in the corresponding area is increased while the speed of the air supply fan in the corresponding area is increased;

[0159] If the actual temperature value does not exceed the preset temperature value, the opening of the electronic expansion valve in the corresponding area is reduced while the speed of the air supply fan in the corresponding area is reduced.

[0160] In the embodiment of the present application, by dynamically adjusting the opening of the electronic expansion valve and the speed of the air supply fan according to the comparison result between the actual temperature value and the preset temperature value, the system can accurately control the air outlet temperature to ensure that the ambient temperature meets the preset requirements.

[0161] Specifically, when the actual temperature exceeds the preset value, the opening of the electronic expansion valve and the speed of the air supply fan are increased to quickly cool down; when the actual temperature does not exceed the preset value, the opening of the electronic expansion valve and the speed of the air supply fan are reduced to maintain the temperature. This adjustment method helps to save energy. At the same time, reducing the speed of the air supply fan can also reduce noise, providing a quieter environment for the workplace.

[0162] That is, in the embodiment of the present application, the system can respond quickly to temperature changes, and by adjusting the operating parameters of the electronic expansion valve and the air supply fan, quickly reach the required temperature setting, thereby improving the response speed of the system.

[0163] Furthermore, in some possible implementations, the control method further includes:

[0164] According to a preset schedule, the target working interval to be used and the non-target working interval not to be used are determined, and the heat exchange units in the target working interval are controlled to operate, and the heat exchange units in the non-target working interval are controlled to stop operating.

[0165] In the embodiment of the present application, by controlling the heat exchange units in the target working area and the non-target working area according to a preset schedule, the system can automatically shut down the heat exchange units in the non-target area when not needed, thereby saving energy. This realizes automated management based on a schedule, reduces manual intervention, improves management efficiency and the intelligence level of the system. Reducing energy consumption during non-working hours or in non-use areas helps reduce operating costs.

[0166] Specifically, the system can intelligently predict the use of workstations in different time periods based on the preset employee schedule, thereby deciding which branch systems need to be started or shut down to achieve precise cooling.

[0167] In order to more clearly understand the solution provided in the above embodiment of the present application, Figure 1 and Figure 2 To explain in detail:

[0168] Refrigeration system architecture design:

[0169] Design the main refrigeration system including condensers, compressors, distribution stations, liquid storage tanks, etc.

[0170] Multiple branches are drawn out from the main refrigeration system, and each branch is equipped with an independent electronic expansion valve, solenoid valve, evaporator, and corresponding air purification module. The electronic expansion valve controls the refrigerant flow rate of the branch pipeline to control the branch cooling capacity, and the solenoid valve is used to open and close the branch pipeline.

[0171] Triple purification air inlet:

[0172] The air inlet is arranged below the work surface, and the work surface is arranged as a mesh structure to facilitate the absorption of debris and harmful gases generated during the production process into the purification device below.

[0173] The first purification device is an electrostatic dust removal device composed of dust collecting electrode plates and discharge electrode plates, which is used to intercept and remove fine particles in the air. The device can be selected according to the needs of the working area environment.

[0174] The second purification device is a high-efficiency filter with an activated carbon layer. The high-efficiency filter is used to further remove fine particles in the air, and the activated carbon adsorption layer is used to remove harmful gases.

[0175] The third-level purification device is a catalytic oxidation device. A suitable catalyst is selected according to the harmful gas components to be treated. Since the catalytic oxidation reaction usually requires a higher temperature to activate the catalyst, a heating device is installed on the catalytic oxidation device. The device can be selected according to the needs of the working area environment.

[0176] Precision cooling air outlet

[0177] The air outlet is set under the work surface, and the air guide plate can flexibly follow the production line workers to provide precise cooling.

[0178] An inter-system windshield, i.e., the above-mentioned partition, is provided between the exits of each work area to ensure that when a system is adjusted specifically, the adjacent systems will not be affected.

[0179] Intelligent control system:

[0180] A sensor network is introduced to monitor the temperature, particle concentration and harmful gas concentration of each workstation in real time. The charge induction sensor and electrochemical sensor 1 detect the untreated air state at the air inlet; the optical particle sensor and electrochemical sensor 2 detect the treated air state; the infrared thermal imaging sensor detects whether there are employees at the workstation and the ambient temperature value of the workstation.

[0181] Purification system control:

[0182] Air enters the system through the air inlet and first passes through the electrostatic precipitator. The discharge electrode plate of the electrostatic precipitator generates a corona effect, which causes the particulate debris carried in the air to acquire an electric charge. Subsequently, the charged particles are guided and adsorbed on the dust collecting electrode plate under the action of the electric field force. In order to dynamically monitor the amount of debris in the incoming air flow, the system's built-in charge sensing sensor detects and records the number of particles in real time. At the same time, the electrochemical sensor continuously monitors and records the concentration of harmful gases in the incoming air flow.

[0183] After air quality monitoring, the airflow enters the next purification stage, that is, the high-efficiency filter and catalytic oxidation device with activated carbon in the interlayer. At this stage, the porous structure of activated carbon can effectively adsorb residual harmful substances and odors, while the catalytic oxidation device uses the oxidation reaction characteristics of the catalyst under mild conditions to convert harmful gases into harmless substances. In this process, the optical particle sensor and electrochemical sensor 2 respectively monitor the number of particles and the concentration of harmful gases in the purified air.

[0184] In order to ensure that the purification effect is sustained and effective, the system dynamically adjusts the working intensity of the electrostatic precipitator and catalytic oxidation device according to the preset standards {standard number of particulate matter and standard concentration of harmful gases}.

[0185] Once the number of particles exceeds the standard number of particles, the discharge amount of the discharge electrode plate of the electrostatic precipitator will be appropriately increased to improve the capture efficiency of the particles. At the same time, the system coordinates the fan to slow down the wind speed and extend the residence time of the gas in the electrostatic precipitator to enhance the purification effect.

[0186] When the concentration of harmful gases exceeds the standard concentration of harmful gases, the temperature of the heating device in the catalytic oxidation device will be increased to enhance the oxidation conversion efficiency of harmful gases. The system also adjusts the fan to slow down the wind speed to ensure that the harmful gases have sufficient conversion time in the catalytic oxidation device.

[0187] To prevent overload and potential system failure, the system pre-sets a safety threshold at the maximum processing capacity. When the number of particles or the concentration of harmful gases in the incoming air flow exceeds this threshold, the system will automatically issue a warning, indicating that the possible processing limit is approaching.

[0188] Furthermore, if the amount of particulate matter or the concentration of harmful gases continues to exceed the standard value for longer than the preset safety time limit, the system will sound an alarm again, warning that the system needs maintenance or that more serious environmental pollution problems have occurred at the source. This is conducive to taking timely measures to avoid affecting the health of operators and the normal operation of the work area.

[0189] Refrigeration system control:

[0190] The infrared thermal imaging sensor continuously monitors the ambient temperature of the workstation and captures the dynamic temperature changes. When the workstation temperature exceeds the preset temperature value, the opening of the electronic expansion valve in the corresponding area is increased while the speed of the air supply fan in the corresponding area is increased to increase the cooling capacity. When the workstation temperature does not exceed the preset temperature value, the opening of the electronic expansion valve in the corresponding area is reduced while the speed of the air supply fan in the corresponding area is reduced to reduce the cooling capacity, thereby achieving a rapid response to temperature changes to achieve dynamic temperature balance.

[0191] It is worth mentioning that the intelligent system can also intelligently predict the use of workstations in various time periods based on the preset employee schedule, thereby deciding which branch systems need to be started or shut down to achieve precise cooling.

[0192] In order to further improve the intelligence level of energy consumption control, the system has built-in standard time thresholds. When the infrared thermal imaging sensor does not detect employee information for a long time during continuous monitoring, the branch system will automatically enter a sleep state and shut down unnecessary energy consumption. At the same time, based on the real-time status of each branch system, the main control system can dynamically adjust the cooling strategy of the entire main system through the distribution station to ensure efficient and uniform cooling distribution and avoid energy waste.
