[0024] The following is combined with Figure 1-Figure 8 This application is described in further detail.

[0025] Reference Figure 1 The present application embodiment discloses an energy-saving control system for a combined air-conditioning unit, including the following modules: Environmental adaptation and heat and humidity load adjustment module, which can intelligently adjust the air treatment mode according to the changes in mine depth and heat and humidity load, including multi-level capacity adjustable air treatment and heat source utilization strategy; Intelligent ventilation and temperature control module, used to intelligently control the fresh air volume and temperature, adjust the humidity of the fresh air state point according to the working conditions, and ensure the comfort of the entire lane and the efficiency of the refrigeration equipment; Dehumidification and refrigeration intelligent judgment module, used to intelligently judge whether the dehumidification or refrigeration conditions are met, and control the connection method of the air cooler to meet the dehumidification demand or reduce energy consumption; The spray cooling and energy recovery module is used to control the spray cooler to cool the refrigeration unit and use the return air in the exhaust system to take away the heat in the spray cooler; Explosion-proof and safety control module, used to ensure that the air-conditioning unit meets explosion-proof requirements; Intelligent monitoring and energy management module, using intelligent control system to dynamically control fresh air volume, temperature, humidity, etc., to achieve energy consumption monitoring and analysis, as well as the application of energy recovery technology; The environmental adaptation module collects data and passes it to the ventilation and temperature control module. The ventilation and temperature control module adjusts parameters according to the data and feeds back to the environmental adaptation module. The dehumidification and refrigeration judgment module receives the signal from the ventilation module and determines the connection method of the air cooler. The spray cooling module and the energy recovery module interact through signals to optimize energy utilization. The explosion-proof and safety module monitors the system status. The intelligent monitoring module summarizes all module information, analyzes energy consumption and issues instructions to form a closed-loop control.

[0026] Correspondingly, the embodiment of the present application provides the following examples for the specific scheme of the energy-saving control system of a combined air-conditioning unit: First, the system monitors key environmental parameters such as temperature, humidity, and gas concentration in real time through high-precision sensors deployed at the wellhead and underground. Based on this data, the system can intelligently analyze environmental adaptability, predict heat and humidity loads, and dynamically adjust ventilation volume and temperature set points to ensure that the underground environment is always within a safe and comfortable range. For example, during high temperatures in summer, the system can automatically increase the fresh air volume and lower the temperature set point, effectively alleviating heat damage in the mine and providing a cool working environment for workers.

[0027] Furthermore, in wet seasons, the system can intelligently judge the ambient humidity, automatically start the dehumidification mode, and achieve efficient dehumidification by optimizing the connection method of the air cooler. At the same time, the system can intelligently select the cooling mode according to the ambient temperature to ensure that the temperature inside the mine is stable within an appropriate range. For example, in the rainy season, the system combines the dehumidification mode with the cooling mode through intelligent judgment, effectively controlling the humidity underground, avoiding corrosion of equipment and tunnels, and maintaining a suitable working temperature.

[0028] In addition, the system can evaluate the energy recovery potential in the exhaust system, and formulate optimization strategies based on the spray cooling needs to achieve efficient energy utilization. For example, in winter, the system can intelligently identify the waste heat in the exhaust air and use this energy to preheat the fresh air through the heat recovery device, reducing the energy required to heat the fresh air and significantly reducing energy consumption.

[0029] At the same time, the system continuously monitors the system status, including key parameters such as temperature, pressure, and gas concentration, and can intelligently assess safety risks, generate and execute safety control strategies, such as emergency shutdown and ventilation adjustment, to ensure safe operation of the system under explosion-proof requirements. For example, when an abnormal gas concentration is detected, the system can immediately start the emergency ventilation mode to reduce the gas concentration and avoid the risk of explosion.

[0030] Furthermore, the system can collect the operation data and control information of all modules in real time, analyze and optimize energy consumption, generate control instructions, optimize the overall operation strategy, and form a closed-loop control. For example, the system can identify time periods with high energy consumption and achieve intelligent energy scheduling and reduce overall energy consumption by adjusting ventilation volume and temperature set points.

[0031] On the other hand, referring to Figure 2 This embodiment also provides an energy-saving control method for a combined air-conditioning unit, which is executed by using the above-mentioned energy-saving control system of a combined air-conditioning unit, and includes the following steps: S1: The environmental adaptation and heat and humidity load adjustment module collects environmental data such as mine depth, heat and humidity load, and conducts real-time analysis to provide a basis for subsequent control decisions.

[0032] Reference Figure 3 , step S1 correspondingly includes the following sub-steps: S11: Use sensors to monitor environmental parameters such as mine depth, temperature, humidity, etc. S12: Preprocess the collected raw data to remove outliers and ensure data quality; S13: Analyze the processed data to determine whether the current environment meets the preset comfort and safety standards; S14: Based on historical data and current environmental parameters, predict future heat and humidity loads to provide a basis for subsequent control.

[0033] For steps S11-S14, the embodiment of the present application provides the following examples.

[0034] During a certain monitoring, the system detected an abnormal increase in temperature in a certain area underground through a temperature sensor, exceeding the preset safety threshold. The system immediately started the preprocessing algorithm to confirm that the data was not an abnormal value, but a true reflection of environmental changes. Subsequently, the system analyzed the processed data and determined that the current environment no longer met the preset comfort and safety standards. Based on historical data and current environmental parameters, the system predicted that the heat load would increase further in the next few hours, so it automatically adjusted the ventilation volume and temperature set point, increased the fresh air volume, and lowered the temperature set point, effectively alleviating the heat damage in the mine and providing a cooler working environment for the staff. At the same time, the system also started the dehumidification mode, and achieved efficient dehumidification by optimizing the connection method of the air cooler, ensuring the comfort and safety of the underground environment.

[0035] Through the above steps, the energy-saving control system can not only monitor and control the mine environment in real time, but also predict future environmental changes, provide a basis for subsequent control strategies, and ensure that the mine air-conditioning system can operate efficiently, safely and energy-efficiently under various working conditions.

[0036] Replay Figure 2 , after step S1, the following steps are also included.

[0037] S2: Based on the collected data, the ventilation and temperature intelligent control module dynamically adjusts the fresh air volume and temperature settings to ensure a comfortable alley environment while optimizing energy use.

[0038] Reference Figure 4 , step S2 correspondingly includes the following sub-steps: S21: Calculate the required fresh air volume based on the heat and humidity load prediction results; S22: Based on environmental adaptability analysis, adjust the temperature set point to ensure comfort; S23: Generate a ventilation system control strategy by combining the fresh air volume and the temperature set point; S24: Execute control strategies, adjust ventilation systems, and collect feedback data for real-time adjustments.

[0039] For steps S21-S24, the embodiment of the present application provides the following examples.

[0040] In one forecast, the system predicted that the heat and humidity load inside the mine would increase significantly in the next few hours, mainly due to the increase in the number of personnel and the increase in the heat generated by the equipment. Based on the forecast results, the system calculated the required fresh air volume and found that the fresh air volume needed to be increased by 20% to meet the ventilation needs. At the same time, the system analyzed the adaptability of the current environment and found that the current temperature was slightly higher than the preset comfort range, so the temperature set point was adjusted from 25°C to 23°C to improve comfort. Combining the fresh air volume and temperature set point, the system generated a ventilation system control strategy, including increasing the fresh air volume, adjusting the air cooler operation mode, and optimizing energy distribution. The system executes the control strategy and adjusts the ventilation system operating parameters, while continuously collecting feedback data such as actual temperature, humidity, ventilation volume, etc. for real-time monitoring and adjustment. During the execution process, the system found that the actual temperature dropped slowly, so it further adjusted the ventilation volume and temperature set point to ensure that the internal environment of the mine quickly reached the preset comfort and safety standards.

[0041] Through the above steps, the energy-saving control system can not only dynamically adjust the ventilation system according to the predicted heat and humidity load, but also monitor and adjust in real time to ensure that the mine air-conditioning system can operate efficiently, safely and energy-savingly under various working conditions, providing strong support for the green, safe and efficient mining of the mine.

[0042] Replay Figure 2 , after step S2, further comprising the following steps: S3: The dehumidification and refrigeration intelligent judgment module intelligently judges and switches the connection mode of the air cooler according to the real-time environmental conditions to achieve the best dehumidification or refrigeration effect.

[0043] Reference Figure 5 , step S3 correspondingly includes the following sub-steps: S31: monitor the ambient humidity and determine whether dehumidification is required; S32: Analyze the ambient temperature and determine whether cooling is required; S33: Intelligently select the connection method of the air cooler according to humidity and temperature requirements; S34: Evaluate dehumidification and cooling performance to ensure that expected goals are achieved.

[0044] For steps S31-S34, the embodiment of the present application provides the following examples.

[0045] During a certain monitoring, the system detected an abnormal increase in underground humidity through a humidity sensor, reaching 95%, exceeding the preset safety threshold. At the same time, the temperature sensor showed that the ambient temperature was 32°C, which was higher than the preset comfort range. The system immediately started the dehumidification and cooling mode, and achieved efficient dehumidification and rapid cooling by intelligently selecting the connection method of the air cooler. During the dehumidification and cooling process, the system continuously collects feedback data, evaluates the dehumidification and cooling effects, ensures that the humidity drops below 80%, and the temperature stabilizes at around 25°C, while monitoring energy consumption to ensure the efficiency and economy of the system operation.

[0046] Through the above steps, the energy-saving control system can not only intelligently select control strategies according to environmental humidity and temperature requirements, but also evaluate the control effect in real time, ensuring that the mine air-conditioning system can operate efficiently, safely and energy-savingly under various working conditions, providing strong support for the green, safe and efficient mining of mines.

[0047] Replay Figure 2 , after step S3, the following steps are also included: S4: The spray cooling and energy recovery module uses the exhaust system to recover energy and optimizes the spray cooling process through signal instructions.

[0048] Reference Figure 6 , step S4 correspondingly includes the following sub-steps: S41: Evaluate the amount of energy that can be recovered in the exhaust system; S42: Analyze whether spray cooling is needed and the intensity of spray cooling; S43: Develop an optimization strategy based on energy recovery potential and spray cooling requirements; S44: Execute optimization strategies and monitor the effectiveness of spray cooling and energy recovery.

[0049] For steps S41-S44, the embodiment of the present application provides the following examples.

[0050] In a certain monitoring, the system evaluated the amount of energy that can be recovered in the exhaust system and found that the exhaust temperature was 35℃, while the fresh air temperature was 20℃. Through the heat exchanger, the system can recover part of the heat in the exhaust air for preheating the fresh air. At the same time, the system analyzed the current ambient temperature and humidity and found that the ambient temperature was 35℃ and the humidity reached 80%. It was determined that the spray cooling system needed to be started to reduce the air temperature. The system combined the energy recovery potential and the spray cooling demand and formulated an optimization strategy. By improving the efficiency of the heat exchanger, 30% of the heat in the exhaust air was recovered for preheating the fresh air. At the same time, the intensity of spray cooling was reduced, achieving efficient energy utilization and stable control of the environment. In the process of executing the optimization strategy, the system continuously monitors the effects of spray cooling and energy recovery to ensure that the temperature of the fresh air after preheating is stable at around 25℃, the ambient temperature after spray cooling drops below 30℃, and the humidity drops below 70%. At the same time, energy consumption is reduced by 20%, achieving efficient energy recovery and stable control of the environment, providing strong support for the green, safe and efficient mining of the mine.

[0051] Through the above steps, the energy-saving control system can not only intelligently formulate optimization strategies based on the amount of recoverable energy in the exhaust system and the spray cooling demand, but also monitor and adjust in real time to ensure that the mine air-conditioning system can operate efficiently, safely and energy-savingly under various working conditions, providing strong support for the green, safe and efficient mining of mines.

[0052] Replay Figure 2 , after step S4, the following steps are also included: S5: The explosion-proof and safety control module continuously monitors the system status to ensure safe operation of the system under explosion-proof requirements.

[0053] Reference Figure 7 , step S5 correspondingly includes the following sub-steps.

[0054] S51: Continuously monitor the system operating status, including temperature, pressure, humidity and wind parameters; S52: Assess safety risks in system operation to ensure compliance with explosion-proof requirements; S53: Generate safety control strategies based on risk assessment, including emergency shutdown and ventilation adjustment; S54: Implement security control strategies, collect feedback, and ensure safe operation of the system.

[0055] For steps S51-S54, the embodiment of the present application provides the following examples.

[0056] During a continuous monitoring, the system detected that the temperature in a certain area underground had risen abnormally to 38°C, exceeding the preset safety threshold. The system immediately started the safety risk assessment program, analyzed the monitoring data, and found that the gas concentration in the area had also risen abnormally, reaching 1.5%, exceeding the preset safety threshold. Based on the risk assessment, the system generated a safety control strategy for emergency shutdown and ventilation adjustment, including shutting down all equipment that may generate electrical sparks, increasing the amount of fresh air, and reducing the gas concentration. The system executes the safety control strategy, adjusts the system operating parameters, and continuously collects feedback data to ensure that the gas concentration drops to a safe range. At the same time, it evaluates energy consumption and environmental impact to ensure the efficiency and economy of the system operation. During the execution process, the system found that the gas concentration quickly dropped below 0.5% after the emergency ventilation program was started, ensuring the safety inside the mine. At the same time, the energy consumption and environmental impact were within an acceptable range, achieving safe, efficient, and energy-saving operation of the system.

[0057] Through the above steps, the energy-saving control system can not only continuously monitor the system operation status and evaluate safety risks, but also intelligently generate and execute safety control strategies to ensure that the mine air-conditioning system can operate safely, stably and energy-efficiently under various working conditions, providing strong support for the green, safe and efficient mining of mines.

[0058] Replay Figure 2 , after step S5, the following steps are also included: S6: The intelligent monitoring and energy management module aggregates all module information, performs energy consumption analysis, issues instructions based on the analysis results, optimizes the overall operation strategy, and forms a closed-loop control.

[0059] Reference Figure 8 , step S6 correspondingly includes the following sub-steps: S61: Summarize the operation data and control information of all modules; S62: Analyze system energy consumption, identify energy saving potential, and optimize energy use; S63: Generate control instructions based on energy consumption analysis and optimize the overall operation strategy; S64: Evaluate the overall performance of the system and adjust the control strategy according to the evaluation results to form a closed-loop control.

[0060] For steps S61-S64, the embodiment of the present application provides the following examples.

[0061] During a certain operation, the system summarized the operation data and control information of all modules, including temperature, humidity, pressure, wind speed, energy consumption, etc. The system conducted an in-depth analysis of these data, identified the distribution and change trend of the system energy consumption, evaluated the current energy efficiency, and identified energy saving potential. The system found that the energy consumption of the air-conditioning system at night was significantly higher than that during the day. By adjusting the night operation mode, unnecessary energy waste was reduced. Based on the energy consumption analysis, the system generated control instructions, adjusted the equipment operation parameters, and optimized the overall operation strategy. For example, by adjusting the operation mode of the air cooler, the system achieved a 15% reduction in energy consumption while maintaining the stability and comfort of environmental control. The system continuously evaluates the overall performance of the system, including energy efficiency, environmental control effect, equipment operation status, etc., and adjusts the control strategy according to the evaluation results to form a closed-loop control. During the execution process, the system found that by optimizing the control strategy, not only energy consumption was reduced, but also the reliability and service life of the equipment were improved, and the efficient, safe, and energy-saving operation of the system was achieved, providing strong support for the green, safe, and efficient mining of the mine.

[0062] Through the above steps, the energy-saving control system can not only summarize and analyze system operation data, identify and optimize energy use, but also continuously evaluate the overall performance of the system, form a closed-loop control, and ensure that the mine air-conditioning system can operate efficiently, safely and energy-efficiently under various working conditions, providing strong support for the green, safe and efficient mining of mines.
