Description

Technical Field

[0001] This application belongs to the field of air conditioning control technology, and in particular relates to an air conditioning control method, device and control system. Background Technology

[0002] Currently, during the use of air conditioners, due to the varying number of terminal devices being turned on, the water volume changes for each terminal device also differ. Therefore, differential pressure bypass valves need to be installed between the main pipelines of the air conditioner's water system to achieve hydraulic balance. However, the installation of differential pressure bypass valves increases the additional installation cost of the air conditioner, and the installation of differential pressure bypass valves can also cause water leakage problems in the air conditioner's water system. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a control method, device, and control system for air conditioning, which eliminates the need for a differential pressure bypass valve, ensuring hydraulic balance while reducing installation costs and avoiding the risk of water leakage.

[0004] In a first aspect, this application provides a method for controlling an air conditioner, wherein the air conditioner fan coil unit includes multiple fan coil units, the multiple fan coil units including a first fan coil unit that is turned on and a second fan coil unit that is not turned on, the method comprising:

[0005] Based on the first number of the first ventilation discs, determine the target number;

[0006] The target number of third wind disks are determined from the second wind disk;

[0007] The two-way valve of the third fan is controlled to open to the first target opening degree. The third fan is used to balance the pressure difference brought by the first fan.

[0008] According to the air conditioning control method of this application, the number of third fan coil units that need to be bypassed in the second fan coil unit is determined by the number of first fan coil units. The two-way valve of the third fan coil unit is controlled to open to the first target opening degree. The hydraulic balance of the air conditioning water system can be achieved without the need to install a differential pressure bypass valve, which can save air conditioning installation costs and avoid the air conditioning leakage problem caused by installing a differential pressure bypass valve.

[0009] According to one embodiment of this application, the method further includes:

[0010] Obtain the temperature of the first fan plate corresponding to the first fan plate;

[0011] Based on the temperature of the first fan plate and the target fan plate temperature corresponding to the first fan plate, the temperature difference of the first fan plate corresponding to the first fan plate is determined.

[0012] Based on the temperature difference of the first fan coil unit, determine the first energy demand coefficient corresponding to the first fan coil unit;

[0013] Based on the first energy demand coefficient and the first number, adjust the opening of the two-way valve of the first fan plate.

[0014] According to one embodiment of this application, when the air conditioner is operating in cooling mode, and the temperature difference of the first fan coil is greater than the first temperature difference threshold, the first energy demand coefficient is positively correlated with the temperature difference of the first fan coil.

[0015] When the temperature difference of the first fan plate is less than or equal to the first temperature difference threshold, the first energy demand coefficient is 0.

[0016] According to one embodiment of this application, when the air conditioner is operating in heating mode, and the temperature difference of the first fan coil is greater than the second temperature difference threshold, the first energy demand coefficient is negatively correlated with the temperature difference of the first fan coil.

[0017] When the temperature difference of the first fan plate is less than or equal to the second temperature difference threshold, the first energy demand coefficient is 0.

[0018] According to one embodiment of this application, adjusting the opening degree of the two-way valve of the first fan coil unit based on the first energy demand coefficient and the first number includes:

[0019] When the first number is determined to be 1, the two-way valve of the first fan is controlled to open to the second target opening degree;

[0020] Alternatively, if the first number is determined to be greater than 1, a fourth wind disk and at least one fifth wind disk are determined in the first wind disk, wherein the energy demand coefficient corresponding to the fourth wind disk is greater than the energy demand coefficient corresponding to the fifth wind disk.

[0021] The two-way valve of the fourth fan coil unit is controlled to open to the third target opening degree, and the two-way valve of the fifth fan coil unit is controlled to open to the fourth target opening degree. The fourth target opening degree is determined based on the difference between the energy demand coefficient corresponding to the fourth fan coil unit and the energy demand coefficient corresponding to the fifth fan coil unit.

[0022] According to one embodiment of this application, the fourth target opening degree is negatively correlated with the difference between the energy demand coefficient corresponding to the fourth wind turbine and the energy demand coefficient corresponding to the fifth wind turbine.

[0023] According to one embodiment of this application, when the first number is less than the bypass number threshold, the target number is negatively correlated with the first number;

[0024] If the first number is greater than or equal to the bypass number threshold, the target number is 0.

[0025] Secondly, this application provides a control device for an air conditioner, wherein the air conditioner fan coil unit includes multiple fan coil units, the multiple fan coil units including an activated first fan coil unit and an inactive second fan coil unit, and the device includes:

[0026] The first processing module is used to determine the target number based on the first number of the first air coils;

[0027] The second processing module is used to determine the target number of third fan coil units from the second fan coil units;

[0028] The third processing module is used to control the two-way valve of the third fan plate to open to the first target opening degree. The third fan plate is used to balance the pressure difference brought by the first fan plate.

[0029] According to the air conditioning control device of this application, the number of third fan coil units that need to be bypassed in the second fan coil unit is determined by the number of first fan coil units. The two-way valve of the third fan coil unit is controlled to open to the first target opening degree. The hydraulic balance of the air conditioning water system can be achieved without the need to install a differential pressure bypass valve, which can save air conditioning installation costs and avoid the air conditioning leakage problem caused by installing a differential pressure bypass valve.

[0030] Thirdly, this application provides a control system for an air conditioner, the system comprising:

[0031] A fan coil unit, wherein the fan coil unit includes multiple fan coils, the multiple fan coils include an activated first fan coil and an unactivated second fan coil, and each fan coil is equipped with a corresponding two-way valve;

[0032] The controller is electrically connected to the fan coil unit and controls the operation of the two-way valve.

[0033] According to the air conditioning control system of this application, the number of third fan coil units that need to be bypassed in the second fan coil unit is determined by the number of first fan coil units. The two-way valve of the third fan coil unit is controlled to open to the first target opening degree. The hydraulic balance of the air conditioning water system can be achieved without the need to install a differential pressure bypass valve, which can save air conditioning installation costs and avoid the air conditioning leakage problem caused by installing a differential pressure bypass valve.

[0043] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0044] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0045] The following is combined with Figures 1-5 The present application provides a detailed description of the air conditioning control method, air conditioning control system, air conditioning control device, and electronic equipment provided in the embodiments of this application through specific implementation methods and application scenarios.

[0046] like Figure 1 As shown, the air conditioning control method includes steps 110 to 130.

[0047] In this embodiment, the air conditioner fan coil unit includes multiple fan coil units, including a first fan coil unit that is turned on and a second fan coil unit that is not turned on.

[0048] The fan coil unit includes a fan, coil, and motor. The coil can circulate chilled water and hot water for heat exchange with the air outside the coil, thereby cooling, dehumidifying, or heating the air to regulate indoor air parameters. The fan coil unit also has a power dialing capability, which allows the corresponding fan coil unit to obtain the required power when it is turned on.

[0049] Step 110: Determine the target number based on the first number of the first wind turbine.

[0050] The first number is the number of the first fan coil units that have been activated in the fan coil unit, and the target number is the number of fan coil units that need to be bypassed.

[0051] For example, a number mapping table can be constructed based on the mapping relationship between the first number and the target number. When determining the first number of the first fan disk that has been turned on, the corresponding target number can be found in the number mapping table.

[0052] Step 120: Determine the target number of third wind disks from the second wind disk.

[0053] The second fan coil unit is the fan coil unit that is not in use, and the third fan coil unit is the fan coil unit used to bypass a portion of the water flow to balance the pressure difference brought by the first fan coil unit.

[0054] In this step, the number of ventilation shafts that need to be bypassed can be determined in the second ventilation shaft based on the target number.

[0055] In practice, after determining the target number, the target number of wind turbines can be randomly selected from the second wind turbine as the wind turbines that need to be bypassed, or the target number of wind turbines can be selected from the second wind turbine as the wind turbines that need to be bypassed according to a certain pattern.

[0056] For example, by obtaining random numbers through a computer, the wind turbine that needs to be bypassed can be randomly selected from the second wind turbine. Alternatively, the wind turbine that needs to be bypassed can be determined to be 6, 7, and 8 based on the previous selection of wind turbine numbers 3, 4, and 5.

[0057] Step 130: Control the two-way valve of the third fan plate to open to the first target opening degree. The third fan plate is used to balance the pressure difference brought by the first fan plate.

[0058] The third wind deflector is the one that needs to be bypassed.

[0059] A two-way valve can be a valve on the coil of a fan coil unit. By controlling the opening and closing of the two-way valve, the flow of water in the coil can be controlled. The first target opening degree is the required opening degree of the two-way valve of the third fan coil unit.

[0060] The first target opening can be preset to a fixed value, which is M steps. After the third fan is determined, the two-way valve of the third fan is controlled to open to the M-step opening.

[0061] In this step, when there is only one target number, the two-way valve of a third fan is opened to the M-step opening degree.

[0062] When there are multiple targets, the opening degree of the two-way valve of each third fan plate is the same, and the opening degree of the two-way valve of each third fan plate is controlled to M steps.

[0063] like Figure 2 As shown, in related technologies, differential pressure bypass valves are usually installed between the main pipelines of the air conditioning water system to achieve hydraulic balance. However, the differential pressure bypass valve increases the additional installation cost of the air conditioning system, and its installation can also cause water leakage problems in the air conditioning water system.

[0064] like Figure 3 As shown in the embodiment of this application, based on the number of the first fan coil units that have been opened in the fan coil unit, the number of the third fan coil units that need to be bypassed in the second fan coil units that have not been opened is determined, and the two-way valves of the third fan coil units that need to be bypassed are controlled to open to the first target opening degree, so as to perform hydraulic balance on the water system of the air conditioner. This eliminates the need to install the differential pressure bypass valve in the water system of the air conditioner, saves the installation cost of the air conditioner, and can also avoid the problem of air conditioner water leakage caused by the installation of the differential pressure bypass valve.

[0065] According to the air conditioning control method provided in the embodiments of this application, the number of third fan coil units that need to be bypassed in the second fan coil unit is determined by the number of first fan coil units in the fan coil unit, and the two-way valve of the third fan coil unit is controlled to open to the first target opening degree. The hydraulic balance of the air conditioning water system can be achieved without installing a differential pressure bypass valve, which can save air conditioning installation costs and avoid the air conditioning leakage problem caused by installing a differential pressure bypass valve.

[0066] In some embodiments, the air conditioning control method may further include:

[0067] Get the temperature of the first fan plate corresponding to the first fan plate;

[0068] Based on the temperature of the first fan plate and the target fan plate temperature corresponding to the first fan plate, determine the temperature difference of the first fan plate corresponding to the first fan plate;

[0069] Based on the temperature difference of the first fan coil unit, determine the first energy demand coefficient corresponding to the first fan coil unit;

[0070] Based on the first energy demand coefficient and the first number, adjust the opening of the two-way valve of the first fan coil unit.

[0071] The temperature of the first fan coil unit can be either the ambient temperature of the environment where the first fan coil unit is located or the temperature of the air conditioner's central controller.

[0072] The first fan plate temperature difference refers to the difference between the temperature of the first fan plate and the temperature of the target fan plate corresponding to the first fan plate.

[0073] The first energy demand factor is the ratio of the actual energy demand for opening the first fan to the rated energy demand for opening the first fan. The first energy demand factor is used to determine the opening degree of the two-way valve corresponding to the first fan.

[0074] The target fan temperature corresponding to the first fan can be the temperature set by the user based on their comfort level, or it can be the temperature set when the air conditioner is in cooling mode.

[0075] For example, when the air conditioner is in cooling mode, the temperature set for cooling mode is 24℃, and the user sets the temperature to 22℃ based on their comfort level.

[0076] In practice, when an air conditioner is working, the greater the difference between the ambient temperature and the set temperature, the greater the power of the air conditioner and the greater the corresponding energy demand.

[0077] For example, if the first number is 1, the opening adjustment of the two-way valve of the first fan plate is only related to the first energy demand coefficient of the first fan plate. When the first number is greater than 1, the opening of the two-way valve of multiple first fan plates is adjusted according to the number of first fan plates and the corresponding first energy demand coefficient.

[0078] In actual operation, the temperature of the first fan plate can be obtained every 15 minutes, the temperature difference of the first fan plate can be re-determined, the first energy demand coefficient corresponding to the first fan plate can be determined, and the opening of the two-way valve of the first fan plate can be adjusted.

[0079] By acquiring the temperature of the first fan coil unit at regular intervals, updating the corresponding first energy demand coefficient, and adjusting the opening of the two-way valve of the first fan coil unit accordingly, the energy demand and water flow of each first fan coil unit in the air conditioning water chiller system can be automatically balanced.

[0080] In some embodiments, when the air conditioner is operating in cooling mode, if the temperature difference of the first fan plate is greater than the first temperature difference threshold, the first energy demand coefficient is positively correlated with the temperature difference of the first fan plate.

[0081] When the temperature difference of the first fan plate is less than or equal to the first temperature difference threshold, the first energy demand coefficient is 0, as shown in Table 1. The first temperature difference threshold can be T5.

[0082] In this embodiment, the first temperature difference threshold can be a value greater than 0, as shown in the seventh column of Table 1. When the temperature difference of the first fan plate is less than or equal to the first temperature difference threshold, it indicates that the temperature of the first fan plate is greater than the target temperature of the first fan plate. At this time, the air conditioner has completed the preset task and enters the standby mode. The actual energy demand of the first fan plate is 0, and the corresponding first energy demand coefficient is 0.

[0085] In Table 1, 130>X1>X2>X3>X4>X5>0, 4>T1>T2>T3>T4≥0, 0>T5>T6>-4.

[0086] As shown in the second to sixth columns of Table 1, if the temperature difference of the first fan plate is greater than the first temperature difference threshold, it indicates that the temperature of the first fan plate has not yet reached the target temperature of the first fan plate. At this time, the air conditioner has not yet completed the preset task and is still in working mode. Moreover, the larger the temperature difference of the first fan plate, the greater the actual energy demand of the first fan plate will be. X1>X2>X3>X4>X5, the corresponding first energy demand coefficients increase in turn, indicating that the corresponding first energy demand coefficients are positively correlated with the temperature difference of the first fan plate.

[0087] In some embodiments, when the air conditioner is operating in heating mode, if the temperature difference of the first fan coil unit is greater than the second temperature difference threshold, the first energy demand coefficient is negatively correlated with the temperature difference of the first fan coil unit.

[0088] When the temperature difference of the first fan plate is less than or equal to the second temperature difference threshold, the first energy demand coefficient is 0, as shown in Table 2. The second temperature difference threshold can be T1.

[0089] The air conditioner can be heated by using a floor heating module or by using a fan coil unit. In the heating mode, the actual energy required by the first fan coil unit is 1.1 times the actual energy required for cooling under the same conditions.

[0090] In this embodiment, the second temperature difference threshold can also be a value greater than 0. As shown in the second column of Table 2, if the temperature difference of the first fan plate is greater than the second temperature difference threshold, it indicates that the temperature of the first fan plate is greater than the target temperature of the first fan plate. At this time, the air conditioner has completed the preset task and enters the standby mode. The actual energy demand of the first fan plate is 0, and the corresponding first energy demand coefficient is 0.

[0091] As shown in columns 3 to 7 of Table 2, if the temperature difference of the first fan plate is greater than the second temperature difference threshold, it indicates that the temperature of the first fan plate has not yet reached the target temperature of the first fan plate. At this time, the air conditioner has not completed the preset task and is still in working mode. Moreover, the smaller the temperature difference of the first fan plate, the greater the actual energy demand of the first fan plate will be. Y1 < Y2 < Y3 < Y4 < Y5 decreases in sequence, indicating that the corresponding first energy demand coefficient is negatively correlated with the temperature difference of the first fan plate.

[0093]

[0094] In Table 2, 0 < Y1 < Y2 < Y3 < Y4 < Y5 < 120, 4 > T1 > T2 > T3 > T4 ≥ 0, 0 > T5 > T6 > -4.

[0095] In some embodiments, adjusting the opening degree of the two-way valve of the first fan coil unit based on a first energy demand coefficient and a first number includes:

[0096] When the first number is determined to be 1, the two-way valve of the first fan coil unit is opened to the second target opening degree.

[0097] Alternatively, if the first number is greater than 1, determine a fourth wind disk and at least one fifth wind disk in the first wind disk, where the energy demand coefficient corresponding to the fourth wind disk is greater than the energy demand coefficient corresponding to the fifth wind disk.

[0098] The two-way valve of the fourth fan coil unit is controlled to open to the third target opening degree, and the two-way valve of the fifth fan coil unit is controlled to open to the fourth target opening degree. The fourth target opening degree is determined based on the difference between the energy demand coefficient corresponding to the fourth fan coil unit and the energy demand coefficient corresponding to the fifth fan coil unit.

[0099] In actual implementation, due to the high water resistance of opening a single first fan coil unit, the two-way valve of the first fan coil unit does not change with the change of energy demand coefficient in order to meet the minimum water flow of the air conditioner.

[0100] In cases where more than one first wind control unit is activated, the fourth wind control unit refers to the first wind control unit with the highest energy demand coefficient among the multiple first wind control units, and the fifth wind control unit refers to the first wind control unit with an energy demand coefficient lower than that of the fourth wind control unit.

[0101] The third target opening degree can be the maximum opening degree of the two-way valve of the fan coil unit.

[0102] In this embodiment, at least one fifth air distribution plate is one of the other air distribution plates in the first air distribution plate, excluding the fourth air distribution plate.

[0103] The first wind disc, which is the wind disc that has been activated, will only have one fourth wind disc and one fifth wind disc when there are only two first wind discs.

[0104] When there are more than two first wind discs, there is only one fourth wind disc and multiple fifth wind discs.

[0105] The fourth target opening is determined based on the difference between the energy demand coefficient corresponding to the fourth wind depot and the energy demand coefficient corresponding to the fifth wind depot. When the difference between the energy demand coefficient corresponding to the fourth wind depot and the energy demand coefficient corresponding to the fifth wind depot is different, the corresponding fourth target opening will also be different.

[0106] In some embodiments, the difference between the fourth target opening degree and the energy demand coefficient corresponding to the fourth wind disk and the energy demand coefficient corresponding to the fifth wind disk is negatively correlated.

[0107] In this embodiment, when the energy demand coefficient of the fourth air distribution plate remains unchanged, the larger the energy demand coefficient of the fifth air distribution plate, the smaller the difference between the energy demand coefficient of the fourth air distribution plate and the energy demand coefficient of the fifth air distribution plate, and the larger the fourth target opening degree corresponding to the fifth air distribution plate.

[0108] In practice, two energy demand coefficient thresholds can be set, denoted as the first energy demand coefficient threshold C% and the second energy demand coefficient threshold D%. The first energy demand coefficient threshold is less than the second energy demand coefficient threshold.

[0109] As shown in Table 3, when the difference between the energy demand coefficients corresponding to the fifth fan is greater than 0 and less than the first energy demand coefficient threshold, the two-way valve of the fifth fan is controlled to open to the third target opening degree. At this time, the fourth target opening degree is equal to the third target opening degree.

[0110] When the difference between the energy demand coefficients corresponding to the fifth fan is greater than the first energy demand coefficient threshold but less than the second energy demand coefficient threshold, the two-way valve of the fifth fan is controlled to open to the E-step opening degree. At this time, the fourth target opening degree is the E-step opening degree.

[0111] When the difference between the energy demand coefficients corresponding to the fifth fan is greater than the second energy demand coefficient threshold, the two-way valve of the fifth fan is controlled to open by F steps. At this time, the fourth target opening is the F-step opening.

[0112] Table 3

[0113]

[0114] In Table 3, the opening size of the third target, the opening size of the E-step, and the opening size of the F-step decrease in sequence, and F is greater than 0.

[0115] In some embodiments, when the first number is less than the bypass number threshold, the target number is negatively correlated with the first number;

[0116] If the first number is greater than or equal to the bypass number threshold, the target number is 0.

[0117] In this embodiment, when the first number is less than the bypass number threshold, the number of fan coil units that are activated is small, the water resistance of the fan coil units is large, and more fan coil units need to be bypassed for hydraulic balance of the water turbine system.

[0118] In actual implementation, as shown in Table 4, when the air conditioner is running in cooling mode and the number of first fan coil units activated is 1, the number of bypass fan coil units required is A1. When the number of first fan coil units activated is 2, the number of bypass fan coil units required is A2. When the number of first fan coil units activated is 3, the number of bypass fan coil units required is A3. When the number of first fan coil units activated is greater than 3, no bypass fan coil units are required.

[0120] Number of first wind disks activated 1 unit 2 units 3 units More than 3 units Number of bypass ventilation panels A1 station A2 Channel A3 Channel No bypass required

[0121] In Table 4, A1, A2 and A3 decrease sequentially, and A3 is greater than 0.

[0124] In Table 5, B1, B2 and B3 decrease sequentially, and B3 is greater than 0.

[0125] As shown in Table 5, when the air conditioner is running in heating mode and the number of first fan coil units activated is 1, the number of bypass fan coil units required is B1. When the number of first fan coil units activated is 2, the number of bypass fan coil units required is B2. When the number of first fan coil units activated is 3, the number of bypass fan coil units required is B3. When the number of first fan coil units activated is greater than 3, no bypass fan coil units are required.

[0126] The air conditioning control method can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0127] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).

[0128] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0129] The air conditioner control method provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the air conditioner control method. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The air conditioner control method provided in this application embodiment will be described below using an electronic device as the execution subject.

[0130] The air conditioner control method provided in this application can be executed by an air conditioner control device. This application uses an air conditioner control device executing the air conditioner control method as an example to illustrate the air conditioner control device provided in this application.

[0131] This application also provides an air conditioner control device.

[0132] like Figure 4 As shown, the air conditioning fan coil unit includes multiple fan coil units, which include an active first fan coil unit and an inactive second fan coil unit. The air conditioning control device includes:

[0133] The first processing module 410 is used to determine the target number based on the first number of the first wind turbines;

[0134] The second processing module 420 is used to determine the target number of third air fans from the second air fans;

[0135] The third processing module 430 is used to control the two-way valve of the third fan to open to the first target opening degree. The third fan is used to balance the pressure difference brought by the first fan.

[0136] According to the air conditioning control device provided in the embodiments of this application, the number of third fan coil units that need to be bypassed in the second fan coil unit is determined by the number of first fan coil units in the fan coil unit, and the two-way valve of the third fan coil unit is controlled to open to the first target opening degree. The hydraulic balance of the air conditioning water system can be achieved without installing a differential pressure bypass valve, which can save air conditioning installation costs and avoid the air conditioning leakage problem caused by installing a differential pressure bypass valve.

[0137] In some embodiments, the first processing module 410 is used to obtain the temperature of the first fan corresponding to the first fan;

[0138] Based on the temperature of the first fan plate and the target fan plate temperature corresponding to the first fan plate, determine the temperature difference of the first fan plate corresponding to the first fan plate;

[0139] Based on the temperature difference of the first fan coil unit, determine the first energy demand coefficient corresponding to the first fan coil unit;
