Abstract
Description
Technical Field
[0001] This application relates to the field of water flow control, and in particular to a multi-zone water flow control method, water system, device and electronic equipment. Background Technology
[0002] Currently, in multi-room water supply systems that use water pumps to supply water to multiple rooms, the water supply lines for multiple rooms are generally connected in parallel, and each room's water supply line has a corresponding water valve and flow switch.
[0003] In existing technologies, water systems typically use two-way valves to control water flow, with one end connected to the water pump outlet and the other to the room's water inlet. In practical applications, when the two-way valve is closed, the resistance in the water pipes increases, causing the water flow to gradually decrease. Furthermore, when multiple areas have their valves open, because the water supply to each room is connected to the pump in parallel, the flow is distributed to each area, further reducing the water flow to each room. Therefore, existing water systems often struggle to achieve optimal cooling / heating performance for every room simultaneously. Summary of the Invention

[0073] 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.
[0074] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. 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.
[0075] To address the technical problem that existing water systems often struggle to achieve optimal cooling / heating effects for each room simultaneously, this application provides a multi-zone water flow control method, water system, device, and electronic equipment that enables the water system to achieve efficient cooling / heating effects for each room at the same time.
[0076] To facilitate understanding of the multi-zone water flow control method provided in the embodiments of this application, the water system used in the multi-zone water flow control method provided in the embodiments of this application will be described in detail below:
[0077] See Figure 1 This is a schematic diagram of a water system provided in an embodiment of this application. Figure 1 As shown, the waterway system may include N regional waterways: regional waterway 1, regional waterway 2, ..., and regional waterway N, where N is a positive integer.
[0078] Each area's water system can supply water to the corresponding area to heat or cool it.
[0079] In one embodiment, each area waterway can be installed in a room, and the room can be cooled or heated by flowing water of a corresponding temperature into the area waterway.
[0080] Optionally, when the temperature of the water flowing into the area's water system is lower than the actual temperature of the room, the area's water system can cool the room.
[0081] Conversely, when the temperature of the water flowing into the area's water system is higher than the actual temperature of the room, the area's water system can heat the room.
[0082] In this embodiment, each regional waterway may include an inlet and an outlet. The inlet of each regional waterway may be connected to a three-way valve. For example, inlet 1A of regional waterway 1 may be connected to three-way valve 1, inlet 2A of regional waterway 2 may be connected to three-way valve 2, and so on. Inlet NA of regional waterway N may be connected to three-way valve N. Compared to existing waterway systems where each regional waterway is connected to a two-way valve, this design prevents significant resistance from being created in the waterway system after the two-way valve is closed, which could lead to a gradual decrease in water flow, increased risk of pipe damage, and potential false alarms from the flow switch protection.
[0083] In one embodiment, the N regional water channels and the three-way valve connected to the inlet of each regional water channel can be connected in the following way:
[0084] First, the three-way valve may include an inlet end (e.g., the inlet end 11 of the first three-way valve), a first outlet end (e.g., the outlet end 12 of the first three-way valve), and a second outlet end (e.g., the outlet end 13 of the first three-way valve).
[0085] Based on this, the inlet 11 of the first three-way valve (i.e., three-way valve 1) can be connected to the outlet of the water supply module, the first outlet 12 can be connected to the inlet 1A of the first regional water circuit, and the second outlet 13 can be connected to the inlet 21 of the next three-way valve. The first three-way valve is the one closest to the water supply module. The water supply module is a device for supplying water; it can be a water pump or other water supply devices, and this embodiment does not limit its application.
[0086] Secondly, the inlet N1 of the aforementioned Nth three-way valve (i.e., three-way valve N) can be connected to a regional waterway (i.e., regional waterway N). -1 The outlet N of the water supply -1 B and the previous three-way valve (i.e., three-way valve N) -1 The second outlet N) -1 3. The first water outlet N2 can be connected to the inlet NA of the Nth regional waterway (i.e., regional waterway N), and the second water outlet N3 and the outlet NB of the Nth regional waterway are connected to the inlet of the water supply module.
[0087] Finally, the inlet M1 of the aforementioned Mth three-way valve (i.e., three-way valve M) can be connected to the previous area water circuit (i.e., area water circuit M). -1 The outlet M -1B and the previous three-way valve (i.e., three-way valve M) -1 The second outlet M) -1 3. The first outlet M2 can be connected to the inlet MA of the Mth area waterway, and the second outlet M3 can be connected to the next three-way valve (i.e., three-way valve M). +1 The water inlet M +1 1. M is a positive integer greater than 1 and less than N. That is, the Mth waterway is the waterway other than the waterway closest to and farthest from the water supply module, and the Mth three-way valve is the three-way valve other than the three-way valve closest to and farthest from the water supply module.
[0088] The water system provided in this application embodiment connects the regional water circuits of each area in a series configuration, and adds a three-way valve to the inlet circuit, with one end connected to the area and the other end connected to the inlet of the next area. During normal operation, the inlet circuit is in the open state. When the inlet valve is closed, the other valve is opened simultaneously, allowing water to flow directly into the inlet of the next room. This prevents the pipe resistance of this circuit from dropping to zero, thereby increasing the water flow and preventing false alarms from the flow switch protection.
[0089] Furthermore, regardless of how the three-way valve is opened, the water from the pump can reach the inlet of each area, ensuring sufficient water flow in each area. The water flow in each area can be adjusted more flexibly according to the temperature difference between the target temperature and the actual temperature of the area, as well as the location of the area, to achieve the cooling / heating effect.
[0090] Based on this, embodiments of this application provide a multi-zone water flow control method for... Figure 1 The water system shown is controlled to more flexibly adjust the water inflow to each area based on the temperature difference between the target temperature and the actual temperature, as well as the location of the area, thereby achieving efficient cooling / heating effects.
[0091] The multi-area water flow control method provided in this application will be further explained and described below with reference to the accompanying drawings and specific embodiments. The embodiments do not constitute a limitation on the embodiments of the present invention.
[0092] See Figure 2 The above is a flowchart of an embodiment of a multi-zone water flow control method provided in this application. Figure 2 The process shown can be applied to Figure 1 The water system shown in the diagram. (For example...) Figure 2 As shown, the process may include the following steps:
[0093] Step 201: Obtain the actual temperature value and target temperature value of the corresponding area of each water channel, and determine the target distance between the water channel of each area and the outlet of the water supply module.
[0094] The aforementioned area refers to the area where the water system supplies water for heating or cooling. It can be a room, a specific area within a room, or an area composed of multiple rooms. This application does not limit this.
[0095] The aforementioned regional waterways refer to the waterways that supply water to the aforementioned regions. Each region may include one regional waterway.
[0096] The above-mentioned actual temperature value refers to the actual temperature of the above-mentioned area. The actual temperature values corresponding to different areas may be the same or different. This application embodiment does not limit this.
[0097] The target temperature value mentioned above refers to the temperature value preset for each region. The target temperature values corresponding to different regions may be the same or different. This application embodiment does not limit this.
[0098] The aforementioned water supply module is a device used to provide water in a water system. It can be a water pump or other water supply devices, and the embodiments of this application do not limit this.
[0099] The aforementioned target distance refers to the distance between the waterway in each area and the outlet of the water supply module. It can be represented by the pipe length between the inlet of the waterway in each area and the outlet of the water supply module, or it can be the approximate distance between the waterway in each area and the outlet of the water supply module. This application embodiment does not limit this.
[0100] In one embodiment, a temperature measuring device, such as a thermometer, may be installed in each area, and this temperature measuring device is connected to the execution subject of this application embodiment. Based on this, the execution subject of this application embodiment can measure the actual temperature value of the corresponding area through each connected temperature measuring device.
[0101] In another embodiment, the executing entity of this application embodiment may have a visual interface through which the user can input the actual temperature value of each area. Based on this, the executing entity of this application embodiment can obtain the actual temperature value of each area through the visual interface.
[0102] In one embodiment, the executing entity of this application embodiment may have a visual interface through which the user can input the actual temperature value and target temperature value of each area. Based on this, the executing entity of this application embodiment can obtain the actual temperature value and target temperature value of each area through the visual interface.
[0103] In this embodiment, when the regional waterway is far from the inlet of the water supply module, the water in the water supply module flows into the far regional waterway, and the temperature of the water changes as it passes through multiple nearby regional waterways. Therefore, the executing entity of this embodiment can determine the target distance between each regional waterway and the outlet of the water supply module based on the inlet temperature corresponding to the inlet of each regional waterway.
[0104] As an exemplary implementation, the inlet temperature of the water inlet for each area can be obtained. Then, based on the inlet temperature, the target distance between the water inlet of each area and the outlet of the water supply module can be determined.
[0105] Optionally, a temperature measuring device can be installed at the inlet of each area waterway. The executing entity of this application embodiment can measure the inlet temperature value corresponding to the inlet through the temperature measuring device installed in each area waterway.
[0106] Furthermore, when the regional water circuit heats the regional water supply, the temperature of its inlet gradually decreases as the distance between the regional water circuit and the outlet of the water supply module increases; when the regional water circuit cools the regional water supply, the temperature of its inlet gradually increases as the distance between the regional water circuit and the outlet of the water supply module increases. Therefore, the corresponding function of inlet temperature and target distance is different for different working modes.
[0107] Based on this, the executing entity of this application embodiment can first determine the objective function of the inlet temperature and the target distance, and according to the objective function, find the distance corresponding to the inlet temperature of each area water channel, and determine the distance as the target distance between the water channel of each area and the inlet of the water supply module. The objective function can be a pre-set function, and different functions can correspond to a trend graph. Based on this trend graph, a distance value corresponding to each inlet temperature can be determined.
[0108] As an exemplary implementation, when the water supply system is used for heating the corresponding area, the water temperature flowing out of the water outlet of the water supply module is relatively high. The water temperature in the water supply system decreases after traveling a certain distance. Therefore, the objective function relating the inlet temperature to the target distance can be determined to be a negative correlation function. Conversely, when the water supply system is used for cooling the corresponding area, the water temperature flowing out of the water outlet of the water supply module is relatively low. The temperature rises after traveling a certain distance. Therefore, the objective function relating the inlet temperature to the target distance can be determined to be a positive correlation function. Both the negative and positive correlation functions can be pre-defined functions obtained through numerous experiments.
[0109] Step 202: Based on the actual temperature value, the target temperature value, and the target distance, determine the target opening degree of the first outlet end of the three-way valve corresponding to each area's waterway.
[0110] The target opening degree mentioned above refers to the opening degree of the first outlet end of the three-way valve of each area waterway, which is the outlet end connected to the water inlet of the area waterway.
[0111] In this embodiment of the application, in order to achieve efficient cooling or heating effects for each area, the target opening degree of the first outlet end of the three-way valve corresponding to the water circuit of each area can be determined according to the temperature difference and target distance of each area.
[0112] As an exemplary implementation, for each water channel area, the target temperature value can be subtracted from the actual temperature value to obtain the target temperature difference for that water channel area. Based on the target temperature difference and the target distance, the target water flow rate for each water channel area can be determined. Then, based on the target water flow rate, the target opening degree of the first outlet end of the three-way valve corresponding to the water channel area can be determined.
[0113] Furthermore, due to the different operating modes of the regional water channels, the relationship between temperature difference and water flow rate varies. For example, when a regional water channel heats the area, the larger the temperature difference, the greater the required water flow rate; when a regional water channel cools the area, since the temperature difference is negative, the smaller the temperature difference, the greater the required water flow rate. Therefore, when determining the target water flow rate for a regional water channel based on the target temperature difference and target distance, the target water flow rate for each regional water channel can be determined according to its operating mode.
[0114] Optionally, when the regional waterway is used to heat the corresponding area, the relationship between the target temperature difference and the water flow rate can be determined to be positively correlated; that is, the larger the target temperature difference, the more water flow rate is required. Based on this, the initial water flow rate corresponding to the regional waterway can be determined according to this positive correlation, and the initial water flow rate can be adjusted according to the target distance of the regional waterway to obtain the target water flow rate corresponding to the regional waterway.
[0115] Optionally, when the regional waterway is used for cooling the corresponding region, the relationship between the target temperature difference and the water flow rate can be determined to be negative. That is, the larger the target temperature difference, the less water flow rate is required. Based on this, the initial water flow rate corresponding to the regional waterway can be determined according to the negative correlation, and the initial water flow rate can be adjusted according to the target distance of the regional waterway to obtain the target water flow rate corresponding to the regional waterway.
[0116] For example, assuming the regional water system is used for cooling the corresponding area, the relationship between the target temperature difference and the water flow rate is as follows (Equation 1):
[0117] W = -T + A (Formula 1)
[0118] Wherein, W is the water flow rate, T is the target temperature difference, and A is the preset value.
[0119] Based on this, assuming the target temperature difference for a certain area is -3 and A is 4, then the initial water flow rate can be obtained as 7.
[0120] Then, the initial water flow rate 7 can be adjusted according to the target distance between the corresponding area's waterway and the water supply module. Assuming the target distance is 3 meters, it indicates the area is far from the water supply module, therefore the initial water flow rate can be adjusted significantly, to 10. Continuing to assume the target distance is 1 meter, it indicates the area is close to the water supply module, therefore the initial water flow rate can be adjusted less, for example, to 7.5.
[0121] In one embodiment, the correspondence between the opening degree of the outlet end of the three-way valve and the water flow rate can be pre-stored. Based on this, the execution subject of this application embodiment can determine the target opening degree corresponding to the target water flow rate from the above correspondence.
[0122] Step 203: Control the opening degree of the first outlet end of the three-way valve corresponding to each area water circuit to the above-mentioned target opening degree, so as to supply water to the area corresponding to the area water circuit according to the water flow rate corresponding to the above-mentioned target opening degree.
[0123] The aforementioned first outlet can be the outlet of the three-way valve that is connected to the water circuit of the corresponding area.
[0124] In this embodiment of the application, in order to ensure that the water flow in the regional waterway reaches the corresponding target water flow, the opening degree of the outlet end of the three-way valve connected to the regional waterway can be set to the target opening degree corresponding to the target water flow.
[0125] The technical solution provided in this application obtains the actual and target temperature values of each area's water circuit, and determines the target distance between the water circuit of each area and the outlet of the water supply module. Based on the actual temperature value, target temperature value, and target distance, the target opening degree of the first outlet end of the three-way valve corresponding to each area's water circuit is determined. The opening degree of the first outlet end of the three-way valve corresponding to each area's water circuit is controlled to be the target opening degree, so that water is supplied to the area corresponding to the area's water circuit according to the water flow rate corresponding to the above-mentioned target opening degree. This technical solution connects the area water circuits of each area in a "series" manner, and adds a three-way valve in the water inlet circuit. One end is connected to the area water circuit, and the other end is connected to the inlet of the next area water circuit. No matter how the three-way valve is opened, the water output from the water supply module can reach the inlet of each area, ensuring that each area has sufficient water flow. According to the temperature difference between the target temperature and the actual temperature of the room and the location of the area, the water inlet of each room can be adjusted more flexibly, thereby achieving more flexible adjustment of the water inlet of each area and thus efficiently achieving the cooling / heating effect.
[0126] To facilitate understanding that the water system provided in this application embodiment can achieve cooling / heating effects more efficiently for each area compared to the water system in the prior art, the following description will first use cooling / heating for each room as an example to illustrate the water system in the prior art:
[0127] See Figure 3 This is a schematic diagram of the structure of a prior art waterway system provided in an embodiment of this application. Figure 3 As shown, the water system in this prior art may include: room 1, room 2, ... room n, wherein the above-mentioned multiple rooms are connected in parallel and are all connected to a water pump. Each room may correspond to a water valve: room 1 is connected to water valve 1, room 2 is connected to water valve 2, ..., room n is connected to water valve n. The inlet A of each water valve is connected to the outlet of the water pump, the outlet B of each water valve is connected to the inlet of the room, and each room is connected to the inlet of the water pump, so that the water in each room can directly flow back to the water pump.
[0128] In existing technology, when a water system is operating with all water valves open, if a room needs to be closed, the corresponding room's water valve will be closed, reducing the number of water valves from n rooms to n-1. This increases the resistance of the water pipes. As more valves are closed, the water resistance increases further. If no measures are taken, the water flow will decrease. When the water flow drops to a certain level, the flow switch will close, indicating that the water pump is not working, triggering the flow switch protection. However, the water pump is still operating at this point. When all n room water valves are open, due to the large number of branch lines, without adjusting the water pump speed, the water flow to each room will decrease, the flow rate will slow down, and the heat exchange will be reduced, making it difficult to guarantee the cooling (heating) effect.
[0129] Based on this, the embodiments of this application provide as follows: Figure 4 The water system shown is designed to efficiently ensure cooling / heating in each room:
[0130] See Figure 4 This is a schematic diagram of another waterway system provided in an embodiment of this application. Figure 4 The system structure shown uses a room as an example to illustrate the water system provided in this application embodiment. For example... Figure 4 As shown, the water system provided in this application embodiment replaces the two-phase water valve in the prior art with a three-way valve, with AB connected to the original inlet water pipe and C connected to the inlet water pipe of the next room.
[0131] Under normal conditions, terminals AB are open and C is closed, consistent with the original water valve. Water entering the room exits through D and flows to the inlet E of the next room. When the water valve is closed, terminal B is closed and terminal C is opened, allowing water to enter the inlet E of the next room via the AC direction. This not only closes the water valve passing through the room but also utilizes the water pipes near room 1 to reduce pipe resistance, preventing the valve from completely shut off, thus minimizing water resistance and preventing false alarms from the flow switch protection.
[0132] Meanwhile, a three-way valve is installed at the water inlet of each room, and the rooms are essentially connected in series. The water flows back to the water pump at the outlet of the nth room. Therefore, no matter how the three-way valve is opened or closed, the water volume at point E and the water volume at point A are the same, ensuring that the water volume in each room is sufficient. The valve opening can be controlled to flexibly control the water volume, resulting in better cooling (heating) effect.
[0133] In this embodiment, the control method for the three-way valve is as follows: the opening adjustment of the three-way valve needs to be based on the temperature difference ΔT (target temperature - actual temperature) in the room and the room location (distinguished by the temperature value at the room's water inlet), i.e., Tn. Because the water inlets of all rooms except room 1 are mixed water, the heating / cooling effect of the mixed water is naturally not as good as the initial effect, so the water valve also needs to be adjusted according to the temperature value of the mixed water. In heating mode, the larger ΔT is, the larger the water flow demand Q is; the lower Tn is, the larger Q is, and the water valve opening K is adjusted accordingly. In cooling mode, the larger ΔT is, the larger the water flow demand Q is; the higher Tn is, the larger Q is, and the water valve opening K is adjusted accordingly. The water valve opening K is positively correlated with the flow rate Q; the larger K is, the larger Q is, the larger the flow velocity V is, and the better the cooling / heating effect. The three-way valve control steps are as follows: detect the room temperature and the temperature value at the water inlet, calculate the temperature difference, obtain the preferred water flow value, and send a control command to the three-way valve.
[0134] The technical solution provided in this application connects the water systems of each room in a series configuration and adds a three-way valve to the inlet water circuit, with one end connected to the room and the other end connected to the inlet of the next room. During normal operation, the inlet water circuit is open. When the inlet water valve is closed, the other valve is opened simultaneously, allowing water to flow directly into the inlet of the next room. This prevents the pipe resistance in this circuit from dropping to zero, thereby increasing the water flow and preventing false alarms from the flow switch protection. Furthermore, regardless of how the three-way valve is open, water from the pump always reaches the inlet of each room, ensuring sufficient water flow in each room. The water flow to each room can be more flexibly adjusted based on the temperature difference between the target and actual temperatures of the rooms, as well as the location of the rooms, to achieve cooling / heating effects.
