Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0022] This application provides a multi-module unit. For example... Figure 1 The diagram shown is an architecture diagram of a multi-module unit according to an embodiment of this application.

[0023] This multi-module unit includes: a main control module, a water circulation pipeline, and multiple modules.

[0024] The main control module connects to multiple modules via a network, used to regulate the water flow rate corresponding to each module. These modules are connected in parallel on a shared water circulation pipeline.

[0025] Furthermore, multiple modules have both cooling and heating functions. Each module is connected to a corresponding terminal device; the types of terminal devices include, but are not limited to, underfloor heating and fan coil units. Multiple modules are connected in parallel on a water circulation pipeline, which provides refrigerant or heat to their respective terminal devices.

[0026] Based on the aforementioned multi-module unit, this application provides a water flow control method. For example... Figure 2 The diagram shown is a flowchart of a water flow control method according to an embodiment of this application.

[0027] Step S210: Monitor the water circuit parameter data of the preset multi-module unit.

[0028] Water circuit parameter data refers to data used to evaluate the hydraulic status of multi-module units.

[0029] Step S220: Adjust the pump speed of the unit water pump in the multi-module unit according to the water circuit parameter data of the multi-module unit.

[0030] A unit water pump refers to a water pump in a multi-module unit that shares a water circulation pipeline with multiple modules and is used to drive the entire water circulation.

[0031] Pump speed setting refers to the operating speed or power setting of the unit's water pump. Different pump speed settings typically correspond to different speeds or power outputs, and adjusting the pump speed setting can change the water output of the unit's water pump.

[0032] Based on the monitored water circuit parameter data, the embodiments of this application dynamically adjust the pump speed of the unit's water pump to optimize the total water flow of the entire water circulation pipeline, so as to ensure sufficient water flow in the water circulation pipeline and avoid insufficient or excessive hydraulic power caused by fixed speed.

[0033] Step S230: After adjusting the pump speed of the unit's water pump, collect the operating parameter data corresponding to each module in operation in the multi-module unit.

[0034] A module in operation refers to a module in a multi-module unit that is performing a cooling or heating task.

[0035] Operating parameter data refers to data that reflects the operating status of a module. The water flow requirement of a module can be determined based on its corresponding operating parameter data.

[0036] Step S240: Adjust the water flow rate of each module in operation according to the operating parameter data of each module in operation.

[0037] Adjusting the water flow rate for each operating module refers to regulating the water flow rate into each module by adjusting the valves or flow control devices of each module to match the operating requirements of each module.

[0038] Water flow rate refers to the volumetric flow rate of water. The water flow rate flowing into a module directly affects the module's heat exchange efficiency and performance. Based on the operating parameter data of each module, the water flow rate flowing into each module can be precisely controlled, which can solve the hydraulic imbalance problem between modules, ensure that each module receives the required amount of water, avoid the "water grabbing" phenomenon, thereby improving the cooling or heating efficiency of each module, reducing energy waste, and enhancing the stability of system operation.

[0039] In this embodiment, water circuit parameter data of a preset multi-module unit can be monitored; the pump speed of the unit's water pumps can be adjusted based on the water circuit parameter data; after adjusting the pump speed, the operating parameter data corresponding to each module in operation within the multi-module unit is collected; and the water flow rate corresponding to each module in operation is controlled based on the operating parameter data. This embodiment first dynamically adjusts the pump speed by monitoring water circuit parameter data to ensure the overall water flow rate meets requirements; then, by collecting the module's operating parameter data, the water flow rate of each module is finely controlled, thus solving the hydraulic distribution problem of individual modules, effectively eliminating the "water competition" phenomenon between modules, ensuring each module receives sufficient water, improving cooling or heating efficiency, enhancing system stability, and reducing overall energy consumption.

[0040] To make the embodiments of this application clearer, the water flow control method of the embodiments of this application will be further described below.

[0041] In this embodiment of the application, water circuit parameter data of a preset multi-module unit can be monitored.

[0042] In this embodiment of the application, after monitoring the water circuit parameter data of the multi-module unit, the pump speed of the unit's water pump can be adjusted according to the water circuit parameter data of the multi-module unit.

[0043] Water circuit parameter data includes, but is not limited to: the flow rate change rate of the outlet main pipe in the multi-module unit and the pressure change rate of the return main pipe in the multi-module unit.

[0044] like Figure 3 The diagram shown is a flowchart of the pump speed adjustment steps according to an embodiment of this application.

[0045] Step S310: Monitor the flow rate change rate of the outlet water main pipe and the pressure rate change rate of the return water main pipe in the multi-module unit.

[0046] The main outlet pipe refers to the main pipeline through which the unit's water pumps deliver water to each module.

[0047] The flow rate change rate of the main outlet pipe is used to quantify the dynamic trend of total water demand. Specifically, the flow rate change rate of the main outlet pipe in a multi-module unit can be monitored by monitoring the water flow rate in that main outlet pipe.

[0048] The return water main refers to the main pipeline from which water flows back from each module to the unit's water pump.

[0049] The pressure change rate of the return water main is used to quantify the dynamic trend of hydraulic resistance. Specifically, the pressure change rate of the return water main in a multi-module unit can be monitored by monitoring the water pressure value.

[0050] Specifically, the water flow rate of the outlet main pipe and the water pressure of the return main pipe in the multi-module unit can be monitored at preset monitoring time intervals. Based on the difference in water flow rate between two consecutive monitoring intervals and the duration of the monitoring period, the rate of change in flow rate of the outlet main pipe can be determined; similarly, based on the difference in water pressure between two consecutive monitoring intervals and the duration of the monitoring period, the rate of change in pressure of the return main pipe can be determined. The duration of the monitoring period can be an empirical value or a value obtained through experiments. For example, the monitoring period could be 30 seconds.

[0051] Step S320: Determine the load change rate of the multi-module unit based on the flow rate change rate of the outlet main pipe and the pressure change rate of the return main pipe.

[0052] The load change rate is used to quantify the dynamic trend of the total load (cooling or heating demand) of a multi-module unit.

[0053] The load change rate can be calculated by linear weighted sum of the flow rate change rate of the outlet main pipe and the pressure change rate of the return main pipe.

[0054] For example, the following formula can be used to determine the load change rate of a multi-module unit: ; in, Indicates the rate of change of load; This indicates the preset water flow weight; Indicates the rate of change of flow rate; This indicates the preset pressure value weight; This indicates the rate of change of pressure.

[0055] Step S330: Adjust the pump speed of the unit water pump in the multi-module unit according to the load change rate, the flow rate change rate and the pressure change rate.

[0056] When the load change rate, the flow rate change rate, and the pressure change rate are all greater than 0, the water pump speed of the unit water pump in the multi-module unit is increased according to the preset first level adjustment gradient.

[0057] When the load change rate, the flow rate change rate, and the pressure change rate are all less than 0, the water pump speed of the unit water pump in the multi-module unit is reduced according to the preset second level adjustment gradient.

[0058] Furthermore, if one of the flow rate change rate and pressure rate change rate is greater than 0 and the other is less than 0, it indicates that the unit's water pump is adjusting. To avoid the problem of misjudging the load change rate due to one value being greater than 0 or the other less than 0, this application embodiment will combine the three values ​​of load change rate, flow rate change rate, and pressure rate change rate to determine the overall change of the multi-module unit: if the load change rate, flow rate change rate, and pressure rate change rate are all greater than 0, it indicates that the overall load of the multi-module unit has increased; if the load change rate, flow rate change rate, and pressure rate change rate are all less than 0, it indicates that the overall load of the multi-module unit has decreased. If the overall load of the multi-module unit increases, the pump speed of the unit's water pump will be increased to increase the water volume in the multi-module unit and avoid hydraulic imbalance between modules due to insufficient water volume; if the overall load of the multi-module unit decreases, the pump speed of the unit's water pump will be decreased to reduce the water volume in the multi-module unit and save energy.

[0059] Since each module in a multi-module unit is connected to terminal equipment, the water flow and pressure in the water circulation pipeline will change as the terminal equipment starts, stops, and is adjusted. For example, each module of the multi-module unit is connected to a fan coil unit in a room. When the heating function in a room is turned on, water begins to flow into the fan coil unit in that room. At this time, the water flow in the main outlet pipe and the pressure in the main return pipe of the water circulation pipeline will increase. Therefore, this embodiment monitors the rate of change of water flow and pressure in real time and uses a weighted formula to integrate them into a comprehensive index (load change rate) that can reflect the load change of the multi-module unit. Based on this comprehensive index, the pump speed is adjusted in a targeted manner. The pump output is adjusted in advance before hydraulic imbalance occurs in each module, thereby fundamentally ensuring the stable distribution of water flow in each module and improving the operational stability of the multi-module unit.

[0060] In this embodiment of the application, after adjusting the pump speed of the unit's water pump, the operating parameter data corresponding to each module in operation in the multi-module unit are collected.

[0061] In this embodiment of the application, after collecting the operating parameter data corresponding to each module in the multi-module unit that is in operation, the water flow rate corresponding to each module in operation can be adjusted according to the operating parameter data corresponding to each module in operation.

[0062] like Figure 4 The diagram shown is a flowchart of water flow regulation steps according to an embodiment of this application.

[0063] Step S410: For each module in operation, determine whether the module is operating with frequency limited based on the corresponding operating parameter data.

[0064] The operating status refers to the module that is performing a cooling or heating task. During operation, the module can report a heartbeat packet once every preset reporting time period. If the heartbeat packet sent by the module is received, it means that the module is in the operating status.

[0065] Operating parameter data includes, but is not limited to: the actual operating frequency of the compressor in the module and the target operating frequency corresponding to the most recent frequency control command.

[0066] Frequency-limited operation refers to the fact that the compressor of the module is forced to operate at a frequency lower than the target operating frequency required by the module's control system due to protection mechanisms (such as protection mechanisms triggered by overload, excessively high exhaust temperature, abnormal power supply, etc.) or performance limitations.

[0067] If the actual operating frequency equals the target operating frequency, it means that the module is operating normally.

[0068] If the actual operating frequency is less than the target operating frequency, it means that the module is operating at a limited frequency.

[0069] Step S420: Determine whether each module in the running state is operating normally; if yes, proceed to step S430; if no, proceed to step S450.

[0070] Normal operation means that the module is not operating with its frequency limited.

[0071] Step S430: When all modules in operation are running normally, determine the water circuit capacity corresponding to each module in operation based on the operating parameter data of the multi-module unit.

[0072] Water capacity refers to the amount of water that a module and its connected end devices can hold, that is, the sum of the water capacity of the module and the water capacity of the end devices connected to the module.

[0073] The specific process of determining the water circuit capacity corresponding to each module in operation will be described in detail later, so it will not be repeated here.

[0074] Step S440: Adjust the water flow rate of each normally operating module according to the water circuit capacity of each module in operation.

[0075] Specifically, the capacity and value of the water circuit corresponding to each module in operation can be calculated. For each module in operation, the proportion of the water circuit capacity corresponding to that module to the total capacity and value is determined as the target proportion for that module. Based on this target proportion, the water inlet control device corresponding to that module is adjusted so that the proportion of the water flow entering that module to the water flow in the main outlet pipe equals the target proportion. The types of water inlet control devices include, but are not limited to, electric regulating valves.

[0076] In this way, modules with larger water capacity will receive more water flow, while modules with smaller water capacity will receive less water flow.

[0077] Step S450: If there are frequency-limited modules among the modules in operation, adjust the water flow rate of each module in operation according to the number of frequency-limited modules and the corresponding operating parameter data of each module in operation.

[0078] If one of the modules in operation is operating with a frequency limit, the actual operating frequency of each module is obtained from the operating parameter data of that module. Based on the actual operating frequency of each normally operating module, the water flow rate of each normally operating module is adjusted.

[0079] Furthermore, the frequency and value of the actual operating frequency corresponding to each module in operation can be calculated; for each module in operation, the proportion of the actual operating frequency to the frequency and value corresponding to the module in operation can be determined as the target proportion corresponding to the module in operation; based on the target proportion, the water inlet control device corresponding to the module in operation can be adjusted so that the proportion of the water flow entering the module in operation to the water flow in the main outlet pipe is equal to the target proportion.

[0080] When multiple frequency-limited modules exist among the modules in operation, for each module in operation, the noise value and cumulative runtime of the module are obtained from the corresponding operating parameter data; based on the noise value and cumulative runtime of each module in operation, the priority of each module in operation is determined; and based on the priority of each module in operation, the water flow rate of each module in operation is adjusted.

[0081] Furthermore, the operating parameter data includes not only the actual operating frequency of the module, but also the noise value and cumulative running time of the module.

[0082] Noise level refers to the noise generated by the hardware in the module during operation. A higher noise level indicates potential problems such as wear, looseness, or poor lubrication in the module's hardware (e.g., compressor, fan), meaning the module's operating state is less stable. Higher noise levels have lower priority, and lower noise levels have higher priority.

[0083] Cumulative runtime refers to the total runtime of a module since it was put into use. Cumulative runtime reflects the potential aging of the module. The longer the cumulative runtime, the more unstable the module's operating state. Furthermore, a longer cumulative runtime corresponds to a lower priority, and a shorter cumulative runtime corresponds to a higher priority.

[0084] Based on the noise value and cumulative runtime of each running module, determine the priority score for each running module; determine the priority of each running module based on its priority score; or determine the priority of the priority range to which the priority score of each running module belongs as the priority of the running module.

[0085] For example, the priority score of a module can be determined using the following formula: ; in, Indicates the priority of the module; This indicates the preset noise weights; This indicates the noise value corresponding to the module; This indicates the maximum noise value corresponding to the module; Indicates the preset lifetime weight; This represents the difference between the module's rated runtime and cumulative runtime. This indicates the rated runtime of the module.

[0086] If the priority score corresponding to each module in operation is determined as the priority of that module in operation, then the score and value of the priority score corresponding to each module in operation can be calculated. For each module in operation, the proportion of the priority score corresponding to that module in operation to the total score and value is determined as the target proportion for that module in operation. Based on the target proportion, the water inlet control device corresponding to that module in operation is adjusted so that the proportion of the water flow entering that module in operation to the water flow in the main outlet pipe is equal to the target proportion.

[0087] If the priority of each module in operation is determined by the score range to which its priority score belongs, then multiple score ranges can be pre-set before determining the priority, each score range corresponding to a priority, and a target ratio can be pre-set for each priority. The target ratio for higher priorities is greater than the target ratio for lower priorities. After determining the priority of the module in operation, the water inlet control device for that module can be adjusted according to the target ratio, ensuring that the proportion of water flow entering the module equals the proportion of water flow in the main outlet pipe.

[0088] The following describes the process of determining the waterway capacity corresponding to a module. For example... Figure 5 The diagram shown is a flowchart of the steps for determining the waterway capacity according to an embodiment of this application.

[0089] Step S510: Determine a feature model that matches the operating parameter data of the multi-module unit; wherein, the feature model is used to record the operating parameter data exhibited by the multi-module unit when a device combination is in an operating state; the device combination refers to each module in the multi-module unit in an operating state and the terminal device connected to each module.

[0090] Step S520: Determine the water circuit capacity corresponding to each module in operation according to the equipment combination indication of each module in the multi-module unit and the terminal equipment connected to each module.

[0091] Since the types of terminal devices connected to each module may not be recorded when connecting each module to terminal devices, but the operating parameter data of the multi-module unit are different during operation due to different combinations of terminal devices, this embodiment of the application can pre-create a feature database and set multiple device combinations before determining the feature model that matches the operating parameter data of the multi-module unit. By simulation or experimentation, each device combination is made to run under different operating conditions to determine the operating parameter data corresponding to the multi-module unit under different operating conditions. Each determined operating parameter data is stored as a feature model in the feature database.

[0092] When implementing the embodiments of this application, a feature model matching the operating parameter data of the multi-module unit is determined in the feature database. Based on the feature model, the types of modules in operation and the types of terminal devices connected to each module can be determined. Since the water capacity of each module and the water capacity of each type of terminal device are known data, the water circuit capacity corresponding to each module in operation can be determined according to the type of terminal device corresponding to each module in operation.

[0093] Furthermore, if the modules in operation indicated by the equipment combination are inconsistent with the modules in operation previously determined when determining whether a module was frequency-limited, the feature module update process can be triggered to re-determine the feature modules in the feature database in order to avoid errors in waterway capacity determination.

[0094] This application embodiment dynamically determines load demand based on the rate of change of total outflow and return pressure, and adaptively adjusts the pump speed to optimize the total water flow. Then, by diagnosing the frequency-limiting status of the modules, it switches between different control strategies: when all modules are operating normally, it achieves precise on-demand water supply based on the water circuit capacity of the corresponding module; when a frequency-limited module exists, it prioritizes water flow to more stable and reliable modules based on the module's actual operating frequency or by introducing a priority mechanism based on noise and lifespan. This application embodiment comprehensively solves the hydraulic imbalance problem caused by fixed pump speeds and module differences, from overall water flow control to local water flow control, improving system operational stability, cooling / heating efficiency, and achieving energy saving and consumption reduction.

[0095] This application also provides a water flow control device. For example... Figure 6 The diagram shown is a structural diagram of a water flow control device according to an embodiment of this application.
