Description

Technical Field

[0001] This application relates to the field of heating, ventilation and air conditioning, and in particular to an air conditioning system. Background Technology

[0002] In related technologies, traditional central air conditioning units with fixed frequency generally suffer from low energy efficiency ratios, low precision of fixed frequency indoor unit terminals and temperature control technology, the prevalence of fixed frequency circulating pumps in water systems, and the fact that while the system is designed to operate at 100% full load, it actually only operates at 50-60% or even lower, making it difficult for the chilled water circulating pump to achieve precise delivery and resulting in huge power losses. When the indoor terminals are turned on at a low load, the units will frequently start and stop, resulting in serious energy waste. Moreover, once the main unit starts or the water temperature reaches the set value, the circulating water pump will still run and consume electricity even when the compressor is in standby mode. Therefore, how to reduce the energy consumption of the air conditioning system has become the technical problem to be solved in this application. Summary of the Invention

[0003] This application aims to at least address one of the technical problems existing in the prior art. Therefore, one objective of this application is to provide an air conditioning system that can reduce the energy consumption of the air conditioning system.

[0005] According to the air conditioning system of this application embodiment, the configuration of multiple air conditioning units, coupled with the independent control of corresponding drive pumps, allows for the selective activation of a corresponding number of air conditioning units and drive pumps based on user load demand feedback from the external circulation flow. This eliminates the frequent start-stop phenomenon of air conditioning units under low load in traditional systems. Furthermore, when the air conditioning unit compressor is in standby mode, the control module can cut off the operation of the corresponding drive pump based on the internal circulation flow detection results, avoiding unnecessary energy consumption. The selective connection design between the first and second water tanks further optimizes the system's water flow distribution, improves the flow matching accuracy between internal and external circulation, reduces energy waste, and significantly improves the overall energy efficiency of the air conditioning system.

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] The following is for reference. Figures 1-2 An air conditioning system 100 according to an embodiment of this application is described.

[0022] An air conditioning system 100 according to an embodiment of this application includes a first water tank 1, a second water tank 2, an air conditioning unit 3, a drive pump 4, and a control module 5. The first water tank 1 and the second water tank 2 are selectively connected to each other. The air conditioning unit 3 is configured as multiple units, each air conditioning unit 3 having a heat exchange channel 31 for communicating with the first water tank 1 and the second water tank 2. The air conditioning unit 3 is provided with an inlet 32 ​​and an outlet 33 communicating with the heat exchange channel 31. The drive pump 4 is configured as multiple units corresponding to the air conditioning unit 3. Each drive pump 4 is located between the inlet 32 ​​of the corresponding air conditioning unit 3 and the first water tank 1, or between the outlet 33 of the corresponding air conditioning unit 3 and the second water tank 2. The control module 5 is provided with a first water flow detection unit and a second water flow detection unit. The first water flow detection unit is used to detect the internal circulation flow between the air conditioning unit 3 and the first water tank 1 or the second water tank 2. The second water flow detection unit is used to detect the external circulation flow between the first water tank 1 or the second water tank 2 and the user end. The control unit controls the corresponding drive pump 4 according to the internal circulation flow and the external circulation flow.

[0023] Understandably, each air conditioning unit 3 corresponds to an independent drive pump 4, allowing the air conditioning system 100 to flexibly adjust the number of air conditioning units 3 participating in operation according to actual load requirements. This eliminates the constraint of a single unit having to start at full load or frequently start and stop. The control module 5 continuously monitors the internal circulation flow between the air conditioning unit 3 and the first water tank 1 or the second water tank 2 through the first water flow detection unit, and simultaneously captures the external circulation flow between the first water tank 1 or the second water tank 2 and the user end in real time through the second water flow detection unit. These two flow data directly reflect the heat exchange requirements of the internal circulation and the actual usage requirements of the user end in the external circulation. Based on these two types of data, the control module 5 independently controls each drive pump 4 to ensure that the operating status of the drive pump 4 matches the current flow balance requirements of the internal and external circulation.

[0024] Furthermore, since the drive pump 4 corresponds one-to-one with the air conditioning unit 3 and can be independently controlled, when the external circulation flow feedback indicates a low user-end load, the control module 5 can start only a small number of air conditioning units 3 and corresponding drive pumps 4 adapted to that load. This avoids the energy waste caused by starting the entire unit regardless of the load in traditional fixed-frequency systems, and completely solves the problem of frequent start-stop of the unit under low load. When the compressor of the air conditioning unit 3 reaches the set water temperature and enters standby mode, the first water flow detection unit detects that the internal circulation flow does not need to be maintained, and the control module 5 will cut off the operation of the corresponding drive pump 4, eliminating the ineffective power consumption of the circulation pump continuing to run when the compressor is in standby mode in traditional systems. The structure in which the first water tank 1 and the second water tank 2 can be selectively connected to each other provides a flexible buffer and distribution space for the adjustment of the internal and external circulation flow rates. This allows the internal circulation flow rate to be dynamically adapted according to the changes in the external circulation flow rate by adjusting the connection status of the water tanks, further improving the matching accuracy of the two types of flow rates and ensuring that the control of the drive pump 4 is more targeted.

[0025] In short, the configuration of multiple air conditioning units 3, coupled with the independent control of corresponding drive pumps 4, allows for the selective activation of a corresponding number of air conditioning units 3 and drive pumps 4 based on user load demand feedback from the external circulation flow. This eliminates the frequent start-stop phenomenon of air conditioning units under low loads in traditional systems. Furthermore, when the compressor of the air conditioning unit 3 is in standby mode, the control module 5 can cut off the operation of the corresponding drive pump 4 based on the internal circulation flow detection results, avoiding unnecessary energy consumption. The selective connection design between the first water tank 1 and the second water tank 2 further optimizes the system's water flow distribution, improves the flow matching accuracy between internal and external circulation, reduces energy waste, and significantly improves the overall energy efficiency of the air conditioning system 100.

[0026] Meanwhile, it should be noted that the first water tank 1 and the second water tank 2 can be selectively connected to each other, which can provide an independent and adjustable flow space for the water flow corresponding to each independent drive pump 4, avoid the water flow generated by different drive pumps 4 during operation from impacting or interfering with each other, and ensure that the water flow output by each drive pump 4 can flow stably to the heat exchange channel 31 of the corresponding air conditioning unit 3, thus ensuring the stability of the internal circulation flow.

[0027] According to some embodiments of the present application, in the air conditioning system 100, the control module 5 is used to control the compressor of each air conditioning unit 3 to be linked with the corresponding drive pump 4 and to keep them in synchronous linkage for start-stop.

[0028] It should be noted that synchronous start-stop can mean that the compressor of each air conditioning unit 3 and the corresponding drive pump 4 are synchronized and operate at the same frequency.

[0029] The synchronous start-stop mechanism not only avoids insufficient internal circulation flow caused by the failure of drive pump 4 to start in time after the compressor starts, or energy waste caused by drive pump 4 starting in advance, but also realizes that the power consumption of drive pump 4 is reduced to zero when the compressor of air conditioning unit 3 reaches the set water temperature and enters the standby state. This fundamentally eliminates the ineffective power consumption of drive pump 4 when the compressor is in standby mode in traditional systems. When the external circulation flow feedback shows that the user end load is low, the control module 5 can start only a small number of air conditioning units 3 and their corresponding drive pumps 4 that are adapted to the load, and the two start and stop synchronously. This not only solves the problem of frequent start-stop of the unit under small load in traditional systems, but also avoids the power loss caused by the mismatch between full load design and low actual operating load through the matching of load and operating status.

[0030] According to some embodiments of the air conditioning system 100 of this application, when the control module 5 determines that the air conditioning unit 3 is in standby mode, the control module 5 controls the corresponding drive pump 4 to remain in a stopped state.

[0031] Furthermore, when the air conditioning unit 3 enters standby mode due to reaching the set water temperature, the drive pump 4 stops, and the drive pump 4 no longer consumes any power, completely eliminating the ineffective power consumption of the circulation pump that continues to run when the compressor is in standby mode in traditional systems. Simultaneously, the standby linkage shutdown design of the compressor and drive pump 4, combined with closed-loop control based on water flow detection, enables the system to match the operating units with load requirements under different load conditions. When the external circulation flow feedback indicates a low load at the user end, the control module 5 can start only a small number of air conditioning units 3 and their corresponding drive pumps 4 that are suitable for the load, and simultaneously stop the corresponding drive pumps 4 when these air conditioning units 3 enter standby mode. This solves the problem of frequent start-stop of the units under low loads and avoids power loss caused by flow mismatch during the delivery process, reducing energy waste, significantly improving overall energy efficiency, and ensuring operational stability.

[0032] According to some embodiments of the present application, in the air conditioning system 100, when one of the air conditioning units 3 is in standby mode, the control module 5 detects the external circulation flow between the first water tank 1 or the second water tank 2 and the user end; when one of the air conditioning units 3 is in operating mode, the first water flow detection unit detects the internal circulation flow between the air conditioning unit 3 where one of the air conditioning units 3 is located and the first water tank 1 or the second water tank 2.

[0033] It should be added that in the existing technology, the water flow detection unit will report an error and stop when the water flow detection value is zero.

[0034] In this application, when the air conditioning unit 3 is in standby mode, the corresponding drive pump 4 remains off, and the internal circulation flow between the air conditioning unit 3 and the first water tank 1 or the second water tank 2 is zero. At this time, the control module 5 switches its detection unit, and the second water flow detection unit performs the detection task, focusing on detecting the external circulation flow between the first water tank 1 or the second water tank 2 and the user end. The external circulation flow will not be zero due to the continuous demand that may exist at the user end, fundamentally avoiding the situation where the first water flow detection unit reports an error due to detecting zero flow. When the air conditioning unit 3 is in operating mode, the drive pump runs synchronously, and the internal circulation forms a stable flow. The control module 5 switches the detection unit again, and the first water flow detection unit detects the internal circulation flow between the air conditioning unit 3 and the first water tank 1 or the second water tank 2, detecting the real-time flow of the internal circulation of the air conditioning unit 3. At this time, the internal circulation flow is not zero, ensuring that the detection unit stably obtains valid data, and similarly avoiding errors.

[0035] It is understood that by adopting the air conditioning system 100 of this application, no additional hardware modifications are required to the first and second water flow detection units. The goal of avoiding errors can be achieved solely through the software logic control of the control module 5, significantly saving the hardware modification costs associated with adaptation and flow detection. Simultaneously, the detection units will not interrupt operation due to errors, and the control module 5 can continuously acquire valid data on the internal or external circulation flow, providing a reliable basis for subsequent operations such as controlling the start / stop and power of the drive pump, valve opening, and the set temperature of the air conditioning unit 3. This avoids control disruptions caused by interrupted detection data and significantly improves the operational stability of the air conditioning system 100.

[0036] According to some embodiments of the present application, an air conditioning system 100 includes a first water tank 1 connected in parallel with at least two air conditioning units 3, and a drive pump 4 is provided between each air conditioning unit 3 and the first water tank 1; wherein the control module 5 controls the power of the drive pump 4 connected to the air conditioning unit 3 according to the working state of the air conditioning unit 3.

[0037] Understandably, the first water tank 1 is connected in parallel with at least two air conditioning units 3, allowing the air conditioning system 100 to selectively start some air conditioning units 3 according to actual load demand, avoiding energy waste caused by forced operation of the entire unit. The control module 5 uses the operating status of the air conditioning units 3 as the basis for regulation, independently adjusting the power of the corresponding drive pump 4 for each operating air conditioning unit 3. This achieves matching between the output of the drive pump 4 and the operating status of the air conditioning unit 3, freeing the drive pump 4 from a fixed output mode and allowing it to dynamically adjust according to the workload of the air conditioning unit 3. When the air conditioning unit 3 is operating at low load, the control module 5 synchronously reduces the power of the corresponding drive pump 4 to avoid energy loss due to excessive output power of the drive pump 4; when the load of the air conditioning unit 3 increases, the power of the drive pump 4 increases accordingly, ensuring that the internal circulation flow meets the heat exchange requirements. The parallel structure of multiple air conditioning units 3 and the first water tank 1, combined with the independent power control of the drive pump 4, enables the system to flexibly respond to different scales of load demand by starting an appropriate number of air conditioning units 3 and adjusting the power of each drive pump 4, further improving the matching accuracy between the internal and external circulation flow.

[0038] According to some embodiments of the present application, the air conditioning system 100 has multiple first water tanks 1, each of which is connected to the water inlet 32 ​​of at least one air conditioning unit 3.

[0039] like Figure 2As shown, the arrangement of multiple first water tanks 1 allows each first water tank 1 to be independently connected to the inlet 32 ​​of at least one air conditioning unit 3, forming multiple independent internal circulation units. This enables multi-point zoned external circulation, breaking the limitation of centralized water supply from a single water tank to all air conditioning units 3. The system can flexibly allocate the number of air conditioning units 3 corresponding to each first water tank 1 based on the user load distribution feedback from the external circulation flow. The independent connection design between multiple first water tanks 1 and air conditioning units 3 achieves modular decomposition of the internal circulation system. When there are regional differences in user load or partial load fluctuations, the system can only activate the first water tank 1 and connected air conditioning units 3 required for the corresponding regional load, while the remaining water tanks and related equipment remain in standby or shutdown state, avoiding energy waste caused by synchronous operation of the entire system. Meanwhile, each first water tank 1 supplies water only to the air conditioning unit 3 connected to it, reducing mutual interference in water flow distribution between different air conditioning units 3, improving the stability of the internal circulation flow, and providing a guarantee for the power regulation of the drive pump 4 and the efficient heat exchange of the air conditioning unit 3. This allows the system to flexibly adjust the number of operating internal circulation units and the operating status of each unit under different load conditions, achieving on-demand energy supply from core aspects such as water flow distribution and the number of equipment started, significantly reducing energy loss and improving the overall operating energy efficiency and load adaptability of the air conditioning system 100.

[0040] Among them, such as Figure 2 As shown, it should be noted that after each first water tank 1 is connected to the air conditioning unit 3, the air conditioning unit 3 is connected to the second water tank 2 to form an internal circulation. Figure 2 The left side is the user's return water end, and the right side is the user's supply water end, forming an external circulation.

[0041] According to some embodiments of the present application, in an air conditioning system 100, the outlet 32 ​​of each air conditioning unit 3 is connected to a second water tank 2.

[0042] like Figure 2As shown, since the water output of all air conditioning units 3 is collected in the second water tank 2, the second water tank 2 needs to collect the water output from each internal circulation unit and ensure a stable external circulation water supply to the user end. Therefore, designing the second water tank 2 as a large-capacity water tank can meet the water storage and external circulation flow supply needs of multiple air conditioning units 3, avoiding water supply fluctuations caused by insufficient water volume. The first water tank 1 only needs to form an independent internal circulation with the corresponding air conditioning unit 3, providing return water storage and internal circulation water flow support for a single or a few associated air conditioning units 3. It does not need to undertake the water volume storage task of the entire system, so it can be designed as a small-capacity water tank, only needing to meet the basic water volume requirements of the corresponding internal circulation. The small capacity limits the internal circulation range of each first water tank 1 to itself and the associated air conditioning unit 3. The internal circulation water flow path is shorter and the water volume requirement is more precise. The drive pump 4 does not need to overcome the additional head loss caused by the long path and large water volume under the large water tank configuration. It only needs to output the head required for the corresponding internal circulation to ensure the water circulation efficiency. Multiple primary water tanks 1 are independently adapted to meet the internal circulation needs of the air conditioning unit 3. The head of each internal circulation tank is matched as needed, avoiding the energy waste caused by the drive pump outputting excessive head to meet the overall system demand in traditional single-tank systems. At the same time, the secondary water tank 2, as a large water tank, ensures the stability of the external circulation water supply, while the primary water tank 1, as a small water tank, precisely matches the internal circulation demand. The two work together to ensure the overall reliability of the system operation and, through on-demand control of the internal circulation head, reduce ineffective energy consumption from the core link of water circulation, significantly improving the energy utilization efficiency of the internal circulation.

[0043] Moreover, the second water tank, as a large water tank, collects the water output from all the air conditioning units 3. Its large volume can buffer the impact force of the water flow discharged from each outlet 32. After the water flows into the large water tank, it can spread smoothly and will not cause violent disturbances due to the concentrated impact of the water flow caused by space limitation. At the same time, the stable water flow state of the large water tank provides a stable foundation for the external circulation water supply.

[0044] According to some embodiments of the present application, an air conditioning system 100 includes a first water tank 1 for receiving return water and a second water tank 2 for discharging water to the user end; wherein at least two connecting pipes 11 are provided between the first water tank 1 and the second water tank 2, and each connecting pipe 11 is provided with a valve body 12 for controlling the opening degree of the connecting pipe 11.

[0045] At least two connecting pipes 11 are provided between the first water tank 1 and the second water tank 2, and each connecting pipe 11 is equipped with a valve body 12 for controlling the opening degree. The control module 5 can combine the internal circulation flow monitored by the first water flow detection unit and the external circulation flow captured by the second water flow detection unit to determine the current supply and demand balance of return water and outlet water in the system, and then adjust the opening degree of the valve body 12 on each connecting pipe 11 accordingly, or even selectively activate some connecting pipes 11. When the external circulation flow feedback indicates a high user end load, the opening degree of the valve body 12 of the relevant connecting pipe 11 can be increased or more connecting pipes 11 can be activated to increase the water flow exchange rate between the two water tanks and ensure that the water supply from the second water tank 2 to the user end meets the demand; when the user end load is low, the opening degree of the valve body 12 can be reduced or some connecting pipes 11 can be closed to reduce the water flow exchange volume and avoid energy loss caused by excessive water flow.

[0046] The combination of the multi-connecting pipe 11 and the valve body 12 enhances the flexibility of water flow regulation between the first water tank 1 and the second water tank 2. It also enables the return water of the first water tank 1 and the outlet water of the second water tank 2 to form a dynamic balance through the control of the opening of the valve body 12, ensuring the matching accuracy of the internal and external circulation flow rates. This provides stable water flow conditions for the operation of the air conditioning unit 3 and the drive pump 4, optimizes the water flow distribution efficiency of the system, and further improves the overall energy efficiency and operational stability of the air conditioning system 100.

[0047] The air conditioning system 100 according to some embodiments of this application further includes: a temperature detection unit and / or a humidity detection unit, wherein the temperature detection unit and / or humidity detection unit are disposed in the temperature adjustment area corresponding to each air conditioning unit 3, and the temperature detection unit and / or humidity detection unit are respectively linked with the control module 5, and the control module 5 controls the highest or lowest set temperature of the air conditioning unit 3 according to the signals collected by the temperature detection unit and / or humidity detection unit.

[0048] Understandably, temperature and / or humidity detection units are installed in the temperature control zones corresponding to each air conditioning unit 3. These units can capture the actual temperature and / or humidity of each zone in real time, ensuring that the collected environmental parameters directly reflect the control requirements of the corresponding zone. This provides a basis for control module 5. Furthermore, because the detection units are linked with control module 5, control module 5 can promptly receive environmental parameter signals from each zone, avoiding any lag in the control basis. Based on the signals collected by the temperature and / or humidity detection units, control module 5 specifically controls the highest or lowest set temperature of the corresponding air conditioning unit 3, ensuring that the operating target of the air conditioning unit 3 aligns with the actual temperature of the zone. To match the actual environmental requirements, when the detection unit reports that the temperature or humidity in the area is higher than the comfort range, the control module 5 can lower the minimum set temperature of the air conditioning unit 3 to ensure that the air conditioning unit 3 outputs sufficient cooling or heating capacity to quickly adjust the environmental parameters; when the detection unit reports that the temperature or humidity in the area is within the comfort range, the control module 5 can raise the minimum set temperature or lower the maximum set temperature to avoid energy waste caused by excessive operation of the air conditioning unit 3. This ensures that the operation of each air conditioning unit 3 closely follows the real-time needs of the corresponding area, which not only improves the accuracy of temperature regulation and user comfort, but also reduces unnecessary energy consumption from the perspective of the unit's operating goals.

[0049] The air conditioning system 100 according to some embodiments of this application further includes: a water level monitoring unit, which is disposed in the first water tank 1 and / or the second water tank 2 and is used to detect the water level of the first water tank 1 and the second water tank 2. The water level monitoring unit is linked with the control module 5. The control module 5 opens the valve body 12 when the water level of the first water tank 1 or the second water tank 2 drops to the lower limit of the set water level within a set time period, and closes the valve body 12 after the water level of the first water tank 1 or the second water tank 2 reaches the set water level.

[0050] The water level monitoring unit is installed in the first water tank 1 and / or the second water tank 2, and can capture the actual water level of the two tanks to ensure that the water level data directly reflects the water supply and demand status within the system, providing a basis for control module 5. Since the water level monitoring unit is linked with control module 5, control module 5 can promptly acquire water level change signals. Based on the water level changes in the first water tank 1 or the second water tank 2 within a set time period, control module 5 executes the control logic for opening and closing valve body 12. When the water level drops to the set lower limit, control module 5 controls valve body 12 to open, enabling water flow replenishment between the first water tank 1 and the second water tank 2, ensuring that the water volume in the tank meets the flow requirements of both internal and external circulation, and avoiding energy waste caused by insufficient water leading to decreased heat exchange efficiency of the air conditioning unit 3 or idling of the driving pump 4. When the water level reaches the set level, control module 5 controls valve body 12 to close, preventing abnormal water pressure or overflow caused by excessive water replenishment, and ensuring the stability of the system's water flow operation. The valve body 12 automatically adjusts based on the water level threshold, ensuring that the water volume in the first water tank 1 and the second water tank 2 is always maintained within a reasonable range, providing stable water support for the efficient operation of the air conditioning unit 3 and the drive pump 4.

[0051] The air conditioning system 100 according to some embodiments of this application further includes: a communication module, which is disposed in the control module 5, and the communication module is adapted to communicate with the user terminal and send target commands to the control module 5.

[0052] The communication module is located in the control module 5, enabling the control module 5 to establish a communication connection with the user terminal. The user can send target commands to the control module 5 through the communication link without on-site operation. As the core control unit of the system, the control module 5, after receiving the target commands from the user terminal, can coordinate with various detection components such as the temperature detection unit, humidity detection unit, and water level monitoring unit. Combining water flow detection data and water tank level, it can coordinate and control the operating status of the air conditioning unit 3, set the power of the temperature-driven pump 4, and the opening degree of the valve body 12 of the connecting pipe 11. This enables remote configuration of system operating parameters. Remote control allows users to adjust the system operating mode at any time according to actual usage needs. When the user terminal load changes or environmental requirements change, the target commands can be quickly fed back to the control module 5. The control module 5 responds instantly and adjusts the operating status of relevant components, avoiding energy waste or decreased comfort caused by on-site control delays.

[0053] The air conditioning system 100 according to some embodiments of this application further includes: a water-use identification module, which is equipped with a camera unit, a voice receiving unit and / or a touch recognition unit. After receiving information and confirming a match, the water-use identification module controls the drive pump 4 corresponding to the water-use identification module to start.

[0054] The water-use identification module is equipped with a camera unit, a voice receiving unit, and / or a touch recognition unit. It can receive usage request information from the water-use terminal from multiple dimensions. After information confirmation and matching, it triggers the corresponding drive pump 4 to start. This binds the start of drive pump 4 to the actual usage needs of the water-use terminal, ensuring that drive pump 4 only starts when there is a valid usage demand and the identity or command matches, avoiding energy waste caused by drive pump 4 running idle when there is no water demand. The configuration of multiple types of identification units broadens the channels for feedback on water-use demand, ensuring that the needs of water-use terminals in different usage scenarios can be accurately captured. The information confirmation and matching process ensures the targeted start of drive pump 4, avoiding invalid operation caused by false triggers. This not only improves the system's response accuracy to load changes and reduces unnecessary energy consumption, but also enhances the system's flexibility and convenience through the adaptation of multiple types of identification units. Demand-matched start-up avoids water flow fluctuations caused by disordered start-up of drive pump 4, ensuring the stability of system operation. Combined with the synergistic effect of other detection units and control module 5, it further optimizes the overall energy efficiency and user experience of the system.

[0055] In some embodiments of this application, an adjustment component 6 is provided on the first water tank and / or the second water tank. The adjustment component 6 includes a pressure relief valve, an air release valve, and a pressure detection unit. The control module 5 can determine whether a preset value has been reached based on the detection value of the pressure detection unit. After the preset value is reached, the pressure relief valve or the air release valve is opened to adjust the pressure of the first water tank and / or the second water tank.

[0056] In some other embodiments of this application, multiple control valves are provided on the internal and external circulation pipelines, and the flow rate of the control valves can be adjusted according to the actual project.
