Description

Technical Field

[0001] This application relates to the field of energy-saving condenser technology, and in particular to a condensing device, a control method for the condensing device, and a device. Background Technology

[0002] In the current field of air conditioning and refrigeration technology, the condenser, as a core heat exchange component, directly affects the system's energy efficiency and operational stability when its cooling method is selected.

[0003] Traditional condensers typically employ a single cooling method. While air-cooled systems offer flexibility and ease of maintenance, their condensing efficiency drops significantly under high temperature and humidity conditions, leading to increased compressor power consumption. Water-cooled systems, on the other hand, while boasting higher heat exchange efficiency, are rigidly dependent on cooling water supply, resulting in high pump energy consumption, easy scaling in pipes, and difficulties in winter freeze protection. Furthermore, they are prone to energy waste under low-load conditions, exhibiting a "powered engine for a small load" phenomenon. To combine the advantages of both, some existing technologies attempt to integrate air and water cooling into a single system, forming a hybrid cooling structure, aiming to achieve complementary operation under different conditions.

[0004] However, most existing hybrid condensing systems that include air cooling and water cooling have a fixed split structure. The refrigerant flow between the air cooling channel and the water cooling channel is usually determined by a valve with a fixed opening. Under complex operating conditions, they often cannot operate at the optimal energy efficiency point, resulting in problems such as low energy utilization. Summary of the Invention

[0017] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.

[0018] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] Figure 1 A structural diagram of a condensation device provided in an embodiment of this application; Figure 2 A flowchart illustrating a control method for a condensing device provided in this application embodiment; Figure 3 This is a structural diagram of a control device for a condensing equipment provided in an embodiment of this application. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Because existing hybrid condensing systems that include both air cooling and water cooling mostly have a fixed flow distribution structure, the refrigerant flow between the air-cooled and water-cooled channels is usually determined by a valve with a fixed opening. Under complex operating conditions, these systems often fail to operate at their optimal energy efficiency point, resulting in low energy utilization. Therefore, this application provides a condensing device, a control method for the condensing device, and an apparatus for doing so.

[0022] like Figure 1 As shown in the figure, this application provides a condensation device, including: an air-cooled flow channel, a water-cooled flow channel, a sensor group, a multi-way diversion valve, an air volume regulating baffle, an electronic expansion valve, and a control module; The sensor group is used to collect environmental data, first equipment status data of the condensing equipment itself, and second equipment status data of the associated equipment of the condensing equipment. In this embodiment, the sensor group includes an ambient temperature sensor, a relative humidity sensor, a condensing pressure sensor, a refrigerant outlet temperature / pressure sensor, a compressor power sensor, and a cooling water inlet / outlet temperature and flow sensor, enabling full-condition data acquisition.

[0023] The input end of the multi-way diversion valve is connected to the refrigerant inlet, the first output end is connected to the air-cooled flow channel, and the second output end is connected to the water-cooled flow channel, which is used to adjust the refrigerant flow rate. In this embodiment, the multi-way diversion valve is installed at the refrigerant inlet of the condenser and has at least three output channels. It can distribute the refrigerant to the air-cooled or water-cooled flow channel as needed. Driven by the control system, it replaces the traditional electric valve + diversion valve combination, achieving precise diversion control with fast response and high adjustment accuracy.

[0024] The air-cooled heat exchanger in the air-cooled flow channel is equipped with an airflow regulating baffle to regulate the airflow, and the water-cooled heat exchanger in the water-cooled flow channel is equipped with an electronic expansion valve to regulate the flow rate of cooling water. In this embodiment, the airflow regulating baffle is driven by a micro motor, and its angle is adjustable to dynamically control the effective flow area of ​​the air-cooled channel. The electronic expansion valve is adjusted in real time by the control system to achieve precise control of the cooling water flow rate.

[0025] like Figure 1As shown, the condensing system also includes an adaptive electronic expansion valve, which is located on the condenser outlet side. By collecting parameters such as condensing pressure, outlet superheat, and ambient temperature, the control system adjusts the opening degree in real time; thereby achieving closed-loop precise control of refrigerant flow, maintaining stable system pressure, and preventing overcooling or gas-liquid mixing.

[0026] The control module is used to determine the building cooling load based on the first equipment status data, and to control the angle of the air volume regulating baffle, the refrigerant distribution ratio of the multi-way diversion valve, and the opening degree of the electronic expansion valve based on the environmental data, the first equipment status data, the building cooling load, and the second equipment status data.

[0027] The control module includes: a mode decision node, which determines the optimal operating mode based on building cooling load, ambient temperature, and status data of the first and second equipment; a flow channel switching control node, which drives the multi-way diversion valve, airflow regulating damper, and electronic expansion valve; an adaptive electronic expansion valve control node, which performs adaptive adjustment; and a communication node, which connects to a remote monitoring platform via an Internet of Things (IoT) module. By employing a distributed control architecture and redundant design, the control module provides the system with higher reliability and fault tolerance, ensuring normal operation even in the event of critical component failure.

[0028] In practical applications, condensing equipment can also communicate with a remote monitoring platform, supporting real-time visualization of equipment status, remote start / stop, parameter configuration, fault alarms and diagnosis; it has a built-in machine learning algorithm module, which includes a control strategy model trained based on historical operating data to achieve self-learning and automatic switching of operating modes; energy efficiency optimization path recommendation; fault prediction and maintenance reminders.

[0029] This application integrates the Internet of Things and machine learning algorithms to enable the system to have remote monitoring, fault diagnosis and self-learning optimization capabilities, thereby further improving the system's intelligence level and operational stability.

[0030] This application embodiment incorporates a multi-way diversion valve for distributing the refrigerant ratio in the air-cooled and water-cooled channels, an airflow regulating baffle for adjusting air volume, and an electronic expansion valve for adjusting cooling water flow in the condensing system. Based on first equipment status data, the building's cooling load is determined. Then, based on environmental data, the first equipment status data, the building's cooling load, and second equipment status data, the angle of the airflow regulating baffle, the refrigerant distribution ratio of the multi-way diversion valve, and the opening degree of the electronic expansion valve are controlled to achieve dynamic adjustment of the cooling capacity of the air-cooled and water-cooled channels. This allows the condensing equipment to switch to the optimal condensing mode under different environmental, building cooling load, and equipment status conditions, thereby improving overall energy efficiency and reducing energy consumption.

[0031] like Figure 2As shown in the figure, this application provides a control method for a condensing device, including: Step S101: Obtain environmental data, first equipment status data of the condensing equipment itself, and second equipment status data of the associated equipment of the condensing equipment; In this embodiment, environmental data refers to the set of physical parameters of the external environment in which the condensing equipment is located, including ambient dry-bulb temperature and current ambient humidity. First equipment status data refers to the internal parameters generated during the operation of the condensing equipment itself, including condensing pressure, refrigerant outlet temperature and pressure, and cooling water inlet / outlet temperature and flow rate. Second equipment status data refers to the operating parameters of associated equipment coupled with the condensing equipment, including compressor power, compressor frequency, and cooling water pump operating status. Associated equipment includes compressors, water pumps, and cooling towers.

[0032] In this step, the control module collects environmental data such as ambient dry-bulb temperature and current ambient humidity in real time through the sensor group. At the same time, it collects first equipment status data such as the condensing pressure of the condensing equipment itself, refrigerant outlet temperature and pressure, compressor power, cooling water inlet and outlet temperature and flow rate, as well as second equipment status data of related equipment such as compressor operating frequency and cooling water pump operating status, to provide a data basis for subsequent mode determination.

[0033] Step S102: Determine the building cooling load based on the first equipment status data; In this embodiment of the application, building cooling load refers to the current cooling capacity required by the building.

[0034] In this step, the control module calculates the heat using the collected chilled water flow rate and the temperature difference between the chilled water supply and return water, using the formula Q=m·c p ·ΔT, (where m is the chilled water flow rate, c p The real-time building cooling load can be calculated using the specific heat capacity (ΔT is the temperature difference between the supply and return water), or the building cooling load can be estimated based on the ratio of the compressor operating frequency to the system's rated cooling capacity.

[0035] Step S103: Determine the operating mode type of the condensing equipment and the corresponding operating control parameters based on the environmental data, the first equipment status data, the building cooling load, and the second equipment status data; In this embodiment, the operating mode type refers to the classification of the working state adopted by the condensing equipment under different operating conditions. Operating mode types include: antifreeze type, cooling water failure type, high load type, low load type, high humidity type, water cooling efficiency reduction type, and transition type, etc. Operating control parameters refer to the control target values ​​set for the actuators to achieve a specific operating mode. Operating control parameters include the opening degree of the electronic expansion valve, the angle of the airflow regulating baffle, and the refrigerant distribution ratio of the multi-way diversion valve, etc.

[0036] In this step, the control module can input environmental data, the first equipment status data, the building cooling load, and the second equipment status data into a preset decision model (e.g., a deep Q-network) so that the preset decision model can output the operating mode type of the condensing equipment and the corresponding operating control parameters.

[0037] Step S104: Control the angle of the airflow regulating baffle, the refrigerant distribution ratio of the multi-way diversion valve, and the opening degree of the electronic expansion valve in the condensing equipment according to the operating control parameters corresponding to the operating mode type.

[0038] In this embodiment, the angle of the airflow regulating baffle refers to the opening angle of the baffle relative to the cross-section of the flow channel; the refrigerant distribution ratio of the multi-way diversion valve refers to the ratio of the refrigerant flow rate entering the air-cooled flow channel to that entering the water-cooled flow channel; and the opening degree of the electronic expansion valve refers to the percentage of the valve used to control the cooling water opening.

[0039] In this step, the control module generates corresponding drive commands based on the operating control parameters and outputs them to each actuator. The motor of the air volume regulating baffle adjusts the baffle angle to change the effective heat exchange area on the air-cooled side, the multi-way diversion valve adjusts the valve core position to redistribute the refrigerant flow into the two flow channels, and the electronic expansion valve adjusts the opening to precisely control the cooling water flow, so that the condensing equipment operates in the optimal state.

[0040] Expansion valve adjustment formula:

[0041] Where: L represents the percentage of real-time cooling load.

[0042] The adaptive electronic expansion valve dynamically adjusts its opening based on feedback from condensing pressure and superheat, ensuring that the system always operates within its high-efficiency range.

[0043] Ultimately, the system returns to "real-time monitoring," continuously collecting operational data and using machine learning algorithms (such as reinforcement learning and time series forecasting) to optimize control parameters, forming a closed loop of "perception-decision-execution-learning" to achieve long-term energy efficiency self-optimization.

[0044] This application embodiment determines the building's cooling load based on first equipment status data. Based on environmental data, first equipment status data, building cooling load, and second equipment status data, it controls the angle of the airflow regulating baffle, the refrigerant distribution ratio of the multi-way diversion valve, and the opening of the electronic expansion valve to achieve dynamic adjustment of the cooling capacity of the air-cooled and water-cooled channels. This enables the condensing equipment to switch to the optimal condensing mode under different environmental, building cooling load, and equipment status conditions, thereby improving overall energy efficiency and reducing energy consumption.

[0045] In another embodiment of this application, step S103, based on the environmental data, the first equipment status data, the building cooling load, and the second equipment status data, determines the operating mode type and the corresponding operating control parameters, including: Step S201: If the ambient dry-bulb temperature is determined to be less than or equal to the first ambient temperature threshold and the duration is greater than the first duration threshold based on the environmental data, the operating mode type is determined to be antifreeze type. In this embodiment, the first ambient temperature threshold refers to the critical value of the ambient temperature used to determine the activation of the antifreeze mode. For example, the first ambient temperature threshold can be 5°C. The first duration threshold refers to the critical value of the duration used to eliminate instantaneous fluctuation interference. For example, the first duration threshold can be 5 minutes. The antifreeze type refers to the operating mode set to prevent the water cooling system from freezing in a low-temperature environment.

[0046] In this step, the control module first determines whether the ambient dry-bulb temperature has reached the first ambient temperature threshold based on environmental data, and checks whether this state continues for more than the first duration threshold. When both conditions are met simultaneously, it indicates that the ambient temperature has dropped to a level that may cause the cooling water to freeze, and the system determines that it can now enter the anti-freeze operation mode.

[0047] Step S202: Determine the operating control parameters corresponding to the antifreeze type. The operating control parameters are used to indicate: adjusting the opening of the electronic expansion valve to the minimum angle, adjusting the angle of the air volume regulating baffle to the maximum opening, and setting the distribution ratio of the multi-way diverter valve to the full air cooling ratio.

[0048] In this embodiment, the minimum angle refers to the minimum opening position that the electronic expansion valve can reach, for example, the minimum angle can be 0 degrees; the maximum opening refers to the maximum opening angle that the air volume regulating baffle can reach, for example, the maximum opening is 100%; the total air cooling ratio refers to the distribution state in which the multi-way diverter valve distributes all the refrigerant to the air cooling channel, for example, the total air cooling ratio is 100%.

[0049] In this step, the operating control parameters corresponding to the antifreeze type can be obtained from the output of the preset decision model. For example, when the ambient dry-bulb temperature is detected to be ≤5℃ for ≥5 minutes, and the operating mode type is determined to be antifreeze, the system can immediately switch to 100% air-cooled operating mode, shut down the water-cooled flow channel, and stop the water pump.

[0050] This application embodiment automatically switches to anti-freeze operation mode in low-temperature environments by setting dual judgment conditions of ambient temperature and duration. The operation control parameters corresponding to the anti-freeze type are used to indicate the closure of the water cooling channel and the full activation of air cooling, which effectively prevents the water cooling system from freezing and being damaged, and improves the reliability of the equipment in winter.

[0051] In another embodiment of this application, step S103, based on the environmental data, the first equipment status data, the building cooling load, and the second equipment status data, determines the operating mode type and the corresponding operating control parameters, including: Step S301: If the ambient dry-bulb temperature is determined to be greater than the first ambient temperature threshold and less than or equal to the second ambient temperature threshold based on the environmental data, determine whether the cooling water flow rate is less than the first flow rate threshold based on the first equipment status data. In this embodiment of the application, the second ambient temperature threshold refers to the upper limit of the ambient temperature used to distinguish between normal and abnormal operating conditions. For example, the second ambient temperature threshold can be 24°C. The first flow threshold refers to the minimum flow threshold used to determine whether the cooling water supply is normal (such as when the water pump stops, the water flow is zero, the water temperature exceeds 32°C, or the water pressure is lower than 0.1MPa). For example, the first flow threshold can be 0, or it can be 15% of the rated flow, etc.

[0052] In this step, the control module first determines whether the ambient dry-bulb temperature is greater than the first ambient temperature threshold and less than or equal to the second ambient temperature threshold based on environmental data, thus eliminating interference from the antifreeze mode and extreme high-temperature conditions. Within this temperature range, it further determines whether the cooling water flow rate is lower than the first flow rate threshold based on the first equipment status data.

[0053] Step S302: If the flow rate of cooling water is determined to be less than the first flow rate threshold based on the first equipment status data, the operating mode type is determined to be a cooling water fault type. In this embodiment, the cooling water fault type refers to the operating mode triggered by abnormal cooling water supply.

[0054] In this step, when the cooling water flow rate is lower than the minimum flow rate required for normal supply, it indicates that the cooling water system has malfunctioned, and the system determines that it has entered the cooling water malfunction category.

[0055] Step S303: Determine the operating control parameters corresponding to the cooling water fault type. The operating control parameters are used to indicate: adjusting the opening of the electronic expansion valve to the minimum angle, adjusting the angle of the air volume regulating baffle to the maximum opening, and setting the distribution ratio of the multi-way diverter valve to the full air cooling ratio.

[0056] In this step, the operating control parameters corresponding to the cooling water fault type can be obtained from the preset decision model output. That is, when the water pump stops, the water flow is zero, the water temperature exceeds 32°C, or the water pressure is below 0.1MPa, the system determines that the operating mode type is a cooling water fault type, and can immediately switch to 100% air-cooled operating mode, shut down the water-cooled flow channel, and stop the water pump.

[0057] This application embodiment automatically switches to pure air-cooled operation mode when the cooling water flow is abnormal, avoiding the decrease in condensation effect or equipment damage caused by interruption or insufficient cooling water supply, and improving the system's fault tolerance and operational safety in the event of cooling water failure.

[0058] In another embodiment of this application, step S103, based on the environmental data, the first equipment status data, the building cooling load, and the second equipment status data, determines the operating mode type and the corresponding operating control parameters, including: Step S401: If the ambient dry-bulb temperature is determined to be greater than the first ambient temperature threshold and less than the third ambient temperature threshold based on the environmental data, the cooling water flow rate is determined to be greater than the second flow rate threshold based on the first equipment status data, and the cooling water inlet temperature is less than or equal to the first water temperature threshold, the building cooling load is greater than or equal to the first load threshold, and the compressor operating frequency is determined to be greater than or equal to the first frequency threshold and the duration is greater than the second duration threshold based on the second equipment status data, the operating mode type is determined to be high load type. In this embodiment, the third ambient temperature threshold refers to the upper limit of the ambient temperature used to determine suitable water cooling operation. For example, the third ambient temperature threshold can be 15℃. When the ambient temperature is ≤15℃, the air cooling capacity is strong, but if the water temperature is too high (e.g., >25℃), the water cooling efficiency may still decrease. The first water temperature threshold refers to the upper limit of the water temperature used to determine that the water cooling system has efficient operating conditions. For example, the first water temperature threshold can be 20℃. In practical applications, the ambient dry-bulb temperature can also be limited to ≤15℃, and the cooling water inlet temperature can be ≤20℃ for ≥30 minutes to prevent false triggering and avoid mode misjudgment caused by instantaneous fluctuations. The cooling water inlet temperature ≤20℃ is a key threshold for achieving efficient water cooling, at which point the water cooling system has energy-saving advantages. The second flow rate threshold refers to the value used to determine the cooling water flow rate. The minimum flow threshold for determining whether the supply is normal is, for example, the second flow threshold can be 85% of the rated flow, where rated cooling capacity refers to the capacity of the outdoor unit; the first load threshold is the lower limit of the building cooling load used to determine high load conditions, for example, the first load threshold can be 75% of the system's rated cooling capacity; the first frequency threshold is the lower limit of the operating frequency used to determine that the compressor is in a high load state, for example, the first frequency threshold can be 90% of the rated frequency; the first duration threshold is the critical value of the duration used to eliminate instantaneous fluctuation interference, for example, the second duration threshold can be 10 minutes, which is used to eliminate instantaneous peak interference and ensure the stability of mode switching; high load type refers to the operating mode in which the system prioritizes water cooling heat dissipation under high temperature and high load conditions.

[0059] In this step, the control module first determines whether the ambient dry-bulb temperature is within the suitable temperature range for water-cooled operation, i.e., greater than the first ambient temperature threshold and less than the third ambient temperature threshold, based on environmental data. Within this temperature range, it further determines whether the cooling water flow rate is sufficient, whether the cooling water inlet temperature meets the conditions for efficient heat exchange, whether the building cooling load reaches the high-load standard, and whether the compressor operating frequency is under high load conditions. All of these conditions must continuously exceed the second duration threshold. When all conditions are simultaneously met, the system can determine that it has entered the high-load mode.

[0060] Step S402: Determine the operating control parameters corresponding to the high load type. The operating control parameters are used to indicate: adjusting the opening of the electronic expansion valve to the first opening range, setting the angle of the air volume regulating baffle to the first angle range, and setting the distribution ratio of the multi-way diversion valve to the water cooling dominant ratio.

[0061] In this embodiment, the first opening range refers to the target opening range of the electronic expansion valve in high-load mode. For example, the first opening range can be 75% to 85%; the first angle range refers to the target angle range of the air volume regulating baffle in high-load mode. For example, the first angle range can be 15% to 25%; the water-cooling dominance ratio refers to the distribution state in which the multi-way diverter valve distributes most of the refrigerant to the water-cooling flow channel. For example, the water-cooling dominance ratio can be 80% to 95%.

[0062] In this step, the operating control parameters corresponding to the high-load type can be obtained from the preset decision model output. When the operating mode type is high-load, the baffle angle in the multi-way diversion valve can be adjusted to above 75°, and the flow area ratio of the water-cooled channel should not be less than 75%, thereby improving the condensation capacity.

[0063] For example, when the ambient dry-bulb temperature is below or equal to 15°C, the cooling water inlet temperature is below or equal to 20°C, the cooling water flow rate is not less than 85% of the rated flow rate, the building's real-time cooling load is not less than 75% of the system's rated cooling capacity, and the compressor's operating frequency is not less than 90% of the rated frequency, the system is deemed to meet the high-load start-up conditions. At this time, the control system drives the baffle motor in the multi-way diversion valve to adjust the baffle angle to above 75°, ensuring that the effective flow area of ​​the water-cooled channel accounts for not less than 70%. Simultaneously, the multi-way diversion valve increases the proportion of refrigerant distributed to the water-cooled channel to above 70%, achieving water-cooled dominant operation.

[0064] Real-time cooling load can be calculated using terminal flow rate and temperature difference: Q = m·c p ·ΔT, (where m is the chilled water flow rate, c p ΔT represents the specific heat capacity, and ΔT represents the temperature difference between the supply and return water.

[0065] This application embodiment uses multi-dimensional condition joint determination to accurately switch to high-load operation mode under high-load conditions, prioritize the use of water cooling heat dissipation, give full play to the high heat exchange efficiency of the water cooling system, effectively reduce compressor power consumption, and improve the system's energy efficiency performance under harsh conditions.

[0066] In another embodiment of this application, step S103, based on the environmental data, the first equipment status data, the building cooling load, and the second equipment status data, determines the operating mode type and the corresponding operating control parameters, including: Step S501: If the ambient dry-bulb temperature is determined to be greater than the first ambient temperature threshold and less than the third ambient temperature threshold based on the environmental data, and the cooling water flow rate is determined to be greater than the second flow rate threshold based on the first equipment status data, and the cooling water inlet temperature is less than or equal to the first water temperature threshold, and the building cooling load is less than the second load threshold, and the compressor operating frequency is determined to be less than the second frequency threshold based on the second equipment status data, and the duration is greater than the first duration threshold, then the operating mode type is determined to be low load type. In this embodiment, the second load threshold refers to the upper limit of the building's cooling load used to determine low-load operating conditions. For example, the second load threshold can be 30% of the system's rated cooling capacity. The second frequency threshold refers to the upper limit of the operating frequency used to determine when the compressor is in a low-load state. For example, the second frequency threshold can be 50% of the rated frequency. Low-load type refers to the operating mode in which the system prioritizes air cooling under low-load conditions.

[0067] In this step, the control module first determines whether the ambient dry-bulb temperature is within the suitable temperature range for water-cooled operation, i.e., greater than the first ambient temperature threshold and less than the third ambient temperature threshold, based on environmental data. Within this temperature range, it further determines whether the cooling water flow rate is sufficient and whether the cooling water inlet temperature meets the conditions for efficient heat exchange. When the above conditions are met, it continues to determine whether the building cooling load is lower than the second load threshold and whether the compressor operating frequency is lower than the second frequency threshold, and whether the above states continue to exceed the first duration threshold. When all conditions are met simultaneously, the system determines that it can enter the low-load mode.

[0068] Step S502: Determine the operating control parameters corresponding to the low load type. The operating control parameters are used to indicate: the opening degree of the electronic expansion valve is within the second opening degree range, the angle of the air volume regulating baffle is adjusted to the second angle range, and the distribution ratio of the multi-way diversion valve is the first air-cooling dominant ratio.

[0069] In this embodiment, the second opening range refers to the target opening range of the electronic expansion valve in low-load mode. For example, the second opening range can be 25% to 35%. The second angle range refers to the target angle range of the air volume regulating baffle in low-load mode. For example, the second angle range can be 65% to 75%. The first air-cooling dominant ratio refers to the distribution state in which the multi-way diverter valve distributes most of the refrigerant to the air-cooling flow channel. For example, the first air-cooling dominant ratio can be 30% to 50%.

[0070] In this step, the operating control parameters corresponding to the low load type can be obtained from the output of the preset decision model.

[0071] This application embodiment automatically switches to air-cooled dominant operation mode under low load conditions, avoiding the energy waste phenomenon of the water-cooled system being overpowered under partial load, while reducing water pump energy consumption and achieving energy-saving operation under light load conditions.

[0072] In another embodiment of this application, step S103, based on the environmental data, the first equipment status data, the building cooling load, and the second equipment status data, determines the operating mode type and the corresponding operating control parameters, including: Step S601: If the current ambient humidity is determined to be greater than or equal to the first humidity threshold, the dew point temperature is greater than or equal to the dew point temperature threshold, and the duration is greater than the third duration threshold, the operating mode type is determined to be high humidity type. In this embodiment, the first humidity threshold refers to the critical relative humidity value used to determine the start-up in a high humidity environment. For example, the first humidity threshold can be 85% relative humidity (RH). When the relative humidity is ≥85%, the air moisture content is high, and the water-cooled heat exchange efficiency decreases significantly (due to limited evaporative cooling capacity). The dew point temperature threshold refers to the critical dew point temperature value used to determine if the air is close to saturation. For example, the dew point temperature threshold can be 20℃. A dew point temperature ≥20℃ indicates that the air is close to saturation, and condensation easily forms on the condenser surface, posing a risk of frost / condensation. The third duration threshold refers to the critical duration value used to eliminate transient fluctuation interference. For example, the third duration threshold can be 15 minutes, with a duration of 15 minutes to prevent false triggering due to transient fluctuations. High humidity type refers to the system's preferred air-cooled heat dissipation operating mode in high-temperature and high-humidity environments.

[0073] In this step, the control module determines whether the current relative humidity has reached or exceeded the first humidity threshold, and whether the dew point temperature has reached or exceeded the dew point temperature threshold, based on environmental data, and whether this state continues for more than the third duration threshold. When all the above conditions are met, it indicates that the ambient humidity is close to saturation, the evaporative cooling capacity of the water cooling system has decreased significantly, and there is a risk of condensation. The system then determines that it can enter the high humidity mode.

[0074] Step S602: Determine the operating control parameters corresponding to the high humidity type. The operating control parameters are used to indicate: the opening degree of the electronic expansion valve is within the third opening degree range, the angle of the air volume regulating baffle is adjusted to the third angle range, and the distribution ratio of the multi-way diversion valve is the second air-cooling dominant ratio.

[0075] In this embodiment, the third opening range refers to the target opening range of the electronic expansion valve in high humidity mode; for example, the third opening range can be 25%~35%. The third angle range refers to the target angle range of the airflow regulating baffle in high humidity mode; for example, the third angle range can be 65%~75%. The second air-cooling dominance ratio refers to the distribution state in which the multi-way diverter valve distributes most of the refrigerant to the air-cooling flow channel; for example, the second air-cooling dominance ratio can be 30%~50%.

[0076] In this step, the operating control parameters corresponding to the high humidity type can be obtained from the output of the preset decision model. For example, when the ambient relative humidity reaches or exceeds 85%RH and the dew point temperature reaches or exceeds 20°C for a duration of not less than 15 minutes, the system determines it to be a high humidity environment and automatically increases the air-cooled flow channel ratio to more than 65%.

[0077] This application embodiment monitors ambient humidity and dew point temperature, and automatically switches to air-cooled dominant operation mode in high humidity environments. This effectively avoids the efficiency reduction caused by the limited evaporative cooling capacity of the water-cooling system, while reducing the risk of condensation on the condenser surface and ensuring stable operation of the system in humid environments.

[0078] In another embodiment of this application, step S103, based on the environmental data, the first equipment status data, the building cooling load, and the second equipment status data, determines the operating mode type and the corresponding operating control parameters, including: Step S701: If the difference between the condensation temperature and the outlet temperature of the cooling water is greater than or equal to the second water temperature threshold and the duration is greater than the fourth duration threshold, the operating mode type is determined to be the water cooling efficiency reduction type. In this embodiment, the second water temperature threshold refers to the critical temperature difference value used to determine a significant decrease in water cooling heat exchange efficiency; for example, the second water temperature threshold can be 8°C. The fourth duration threshold refers to the critical duration value used to exclude instantaneous fluctuation interference; for example, the fourth duration threshold can be 10 minutes. The water cooling efficiency decrease type refers to the operating mode triggered when the system's heat exchange capacity on the water cooling side is insufficient.

[0079] In this step, the control module calculates the difference between the condensation temperature and the cooling water outlet temperature based on the first equipment status data, and compares this difference with a second water temperature threshold. When the temperature difference reaches or exceeds the second water temperature threshold, and this state continues to exceed a fourth duration threshold, it indicates that the heat exchange capacity of the water-cooled side can no longer meet the current heat dissipation demand, and the system determines that it has entered the water cooling efficiency decline type.

[0080] Step S702: Determine the operating control parameters corresponding to the type of water cooling efficiency reduction. The operating control parameters are used to indicate: adjusting the angle of the air volume regulating baffle to the fourth angle range, setting the opening of the electronic expansion valve to the fourth opening range, and setting the distribution ratio of the multi-way diverter valve to the third air cooling dominant ratio.

[0081] In this embodiment, the fourth angle range refers to the target angle range of the airflow regulating baffle in the water-cooling efficiency reduction mode; for example, the fourth angle range can be greater than 70%. The fourth opening range refers to the target opening range of the electronic expansion valve in the water-cooling efficiency reduction mode; for example, the fourth opening range can be less than 30%. The third air-cooling dominance ratio refers to the distribution state in which the multi-way diverter valve distributes most of the refrigerant to the air-cooling flow channel; for example, the third air-cooling dominance ratio can be greater than 70%.

[0082] In this step, the operating control parameters corresponding to the type of water cooling efficiency decline output by the preset decision model can be obtained. For example, when the difference between the condensing temperature and the cooling water outlet temperature reaches or exceeds 8°C and lasts for no less than 10 minutes, the system determines that the water cooling efficiency has declined and automatically increases the air cooling ratio to over 70%.

[0083] This application embodiment monitors the temperature difference between the condensation temperature and the cooling water outlet temperature, and automatically increases the proportion of air cooling heat dissipation when the water cooling heat exchange efficiency decreases. This achieves dynamic compensation for the performance degradation of the water cooling side and ensures the continuous and efficient operation of the system under conditions such as abnormal cooling water temperature or scaling on the water cooling side.

[0084] In another embodiment of this application, step S103, based on the environmental data, the first equipment status data, the building cooling load, and the second equipment status data, determines the operating mode type and the corresponding operating control parameters, including: Step S801: If the building cooling load is between the second load threshold and the first load threshold, the ambient dry bulb temperature is determined to be within the first ambient temperature range based on the environmental data, the cooling water inlet temperature is determined to be within the first water temperature range based on the first equipment status data, and the difference between the condensation temperature and the cooling water outlet temperature is within the second water temperature range, and the duration is greater than the fifth duration threshold, the operation mode type is determined to be transition type. In this embodiment, the first ambient temperature range refers to the suitable ambient temperature range for transitional operation; for example, the first ambient temperature range can be 15°C to 25°C. The first water temperature range refers to the suitable cooling water inlet temperature range for transitional operation; for example, the first water temperature range can be between 20°C and 28°C. The second water temperature range refers to the water-cooled heat exchange temperature difference range used to determine the transitional operation; for example, the first water temperature range can be between 4°C and 8°C. The fifth duration threshold refers to the critical value of the duration used to exclude instantaneous fluctuation interference; for example, the fifth duration threshold can be 10 minutes. The transition type refers to the hybrid cooling operation mode adopted by the system under moderate load and suitable environmental conditions.

[0085] In this step, the control module first determines whether the building's cooling load is between the second load threshold and the first load threshold, i.e., in the medium load range. Under this condition, it further determines whether the ambient dry-bulb temperature is within the first ambient temperature range, whether the cooling water inlet temperature is within the first water temperature range, and whether the difference between the condensate temperature and the cooling water outlet temperature is within the second water temperature range, and whether the above conditions continue to exceed the fifth duration threshold. When all conditions are met simultaneously, the system determines that it can enter the transition type.

[0086] Step S802: Determine the operating control parameters corresponding to the type of water cooling efficiency reduction. The operating control parameters are used to indicate: adjusting the angle of the air volume regulating baffle to the fourth angle range, setting the opening of the electronic expansion valve to the fourth opening range, and setting the distribution ratio of the multi-way diverter valve to the third air cooling dominant ratio.

[0087] In this embodiment, the fifth opening range refers to the target opening range of the electronic expansion valve in the transition mode. For example, the fifth opening range can be 30% to 70%. The fifth angle range refers to the target angle range of the air volume regulating baffle in the transition mode. For example, the fifth angle range can be 30% to 70%.

[0088] In this step, the operation control parameters corresponding to the transition type can be obtained from the output of the preset decision model.

[0089] For example, when the building's real-time cooling load is between 30% and 75% of the system's rated cooling capacity, the ambient dry-bulb temperature is between 15°C and 25°C, the cooling water inlet temperature is between 20°C and 28°C, and the difference between the condensing temperature and the cooling water outlet temperature is between 4°C and 8°C, and this state lasts for at least 10 minutes, the system is determined to be in a transitional operating condition. At this time, the system enters a hybrid operation mode, which is regulated in conjunction with a multi-way diverter valve and an adjustable baffle: the baffle angle (ranging from 25° to 70°) is dynamically calculated using linear interpolation based on the real-time cooling load ratio, and the baffle motor is driven to achieve precise adjustment; at the same time, the multi-way diverter valve distributes refrigerant proportionally to the air-cooled and water-cooled channels to ensure that the system operates stably in the range with the highest energy efficiency and the lowest risk of condensation.

[0090] Real-time cooling load percentage = sum of indoor unit operating capacity / sum of all indoor unit capacity in the system. A large real-time cooling load percentage indicates a large cooling demand and a large baffle angle.

[0091] This application embodiment achieves stable system operation in the range of highest energy efficiency and lowest condensation risk by adopting a hybrid operation mode under transitional conditions and dynamically adjusting the distribution ratio of air cooling and water cooling according to real-time cooling load. This avoids sudden performance changes during mode switching and improves the smoothness of system operation and overall energy efficiency under varying operating conditions.

Figure 3 As shown, it includes: The acquisition module 11 is used to acquire environmental data, first equipment status data of the condensing equipment itself, and second equipment status data of the associated equipment of the condensing equipment; The first determining module 12 is used to determine the building cooling load based on the first device status data; The second determining module 13 is used to determine the operating mode type of the condensing equipment and the corresponding operating control parameters based on the environmental data, the first equipment status data, the building cooling load and the second equipment status data. The control module 14 is used to control the angle of the air volume regulating baffle, the refrigerant distribution ratio of the multi-way diversion valve, and the opening degree of the electronic expansion valve in the condensing equipment according to the operation control parameters corresponding to the operation mode type.

[0093] In this embodiment of the application, a training method for a preset decision model is also provided, the method comprising: After the system finishes its daily operation, the control system automatically uploads the day's operating data (including environmental parameters, condensing pressure, compressor power, flow split ratio, baffle angle, expansion valve opening, etc.) to the remote monitoring platform to form a historical database.

[0094] An offline training task is launched once a week. The preset decision model may include the Deep Q-Network (DQN) algorithm, with "maximizing system COP" as the reward function. Input variables include: ambient temperature, humidity, real-time building load, cooling water temperature and flow rate, etc.

[0095] State space: 8-dimensional vector (normalized), Action space: discretized into 990 combinations (diversion ratio, baffle angle, expansion valve opening), Reward function:

[0096] After training, the output is the preset policy model for optimal control.

[0097] Energy efficiency (weight 0.7): For instantaneous energy efficiency ratio, it can be calculated as COP = cooling capacity / total power consumption. The higher the COP value, the more energy-efficient it is. This is the main optimization goal. Note: COP usually needs to be normalized (e.g., divided by the maximum theoretical COP) to ensure that it is between 0 and 1. Otherwise, an excessively large value may mask other items.

[0098] Comfort / Stability (weight 0.2): This refers to the suction superheat, which corresponds to the difference between the compressor suction port temperature and the evaporation temperature. The target value is 5°C, and the penalty mechanism is: if ΔT = 5°C, this value is 1. 0 = 1 (full marks). If the deviation reaches 5℃ (i.e., the actual temperature is 0℃ or 10℃), the value of this item is 1. 1 = 0 (no reward). If the deviation exceeds 5°C, this term may become negative (depending on whether the implementation code has truncation). Purpose: To prevent liquid slugging (too low superheat) or insufficient / overheating (too high superheat).

[0099] Safety / Stress Item (Weight 0.1): For condensation pressure, The target condensation pressure (the optimal pressure obtained from a table based on the ambient temperature). This is the maximum allowable pressure threshold (safety upper limit) of the system. When the actual pressure equals the target pressure, this value is 1. The further the pressure deviates from the target (closer to Pmax), the smaller this value becomes, even negative. The purpose is to prevent high-pressure tripping and to avoid poor compressor lubrication caused by excessively low pressure.

[0100] Represents the optimal strategy. Select operators for actions.

[0101] The core logic of the pre-defined decision model is: Perception: Read 8 parameters (environmental parameters and system parameters).

[0102] Decision: The AI ​​model calculates which of the 990 mechanical combinations will result in the highest COP (70% weight), the superheat closest to 5°C (20% weight), and the most stable condensing pressure (10% weight).

[0103] Execution: Send the selected combination to the hardware for execution.

[0104] Iteration: Through continuous trial and error, the model learns how to automatically find the optimal solution under different weather and load conditions.
