In the process of realizing this application, the inventor found that there are at least the following technical problems in the prior art: in a larger space environment, due to the installation location of the air conditioner or the space environment, the airflow organization is often unstable, which will cause uneven temperature and humidity in the space. When the indoor temperature and humidity are uneven, this will cause some places in the larger space environment to have higher temperatures and some places to have lower temperatures, affecting the temperature control in the space environment. Moreover, due to the uneven indoor temperature and humidity, the central control device will constantly adjust each air-conditioning device, so that the operation of the air-conditioning components of each air-conditioning device will also fluctuate, which will also affect the service life of the air-conditioning device.

[0021] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the scope of protection of the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] In the following description, reference is made to “some embodiments” which describe a subset of all possible embodiments, but it should be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0024] See also Figure 1, is a schematic diagram of an optional application scenario of the control method of the air-conditioning system provided in an embodiment of the present application. The application scenario diagram includes a control device 100 of the air-conditioning system (hereinafter referred to as the control device 100), multiple air-conditioning devices 200 and an ambient temperature sensor 300, wherein the air-conditioning devices 200 and the ambient temperature sensor 300 can be respectively connected to the control device 100 for wireless or wired communication. Multiple air-conditioning devices 200 are installed at a position in the spatial environment, and the ambient temperature sensor 300 is used to collect the actual ambient temperature of the spatial environment. In the spatial environment, the user can also set the desired ambient setting temperature, for example, by setting the ambient setting temperature through a remote control, and expecting the temperature of the spatial environment to reach the ambient setting temperature. It can be understood that the ambient setting temperature is the temperature desired by the user, and the actual ambient temperature is the temperature collected by the ambient temperature sensor 300 set at a certain position in the spatial environment. The air-conditioning device 200 includes an air-conditioning temperature sensor 201. The air-conditioning temperature sensor 201 is used to collect the actual air outlet temperature of the air-conditioning device 200 where it is installed. The control device 100 is used to obtain the actual air outlet temperature collected by the air conditioning temperature sensor of each air conditioning device 200, and also obtains the actual ambient temperature and the ambient set temperature to calculate the set air outlet temperature for the entire air conditioning system. After the control device 100 sets the air outlet temperature, it sends it to each air conditioning device 200. Each air conditioning device 200 then controls its operation based on the obtained set air outlet temperature.

[0025] like Figure 2 As shown, Figure 2 This is a schematic diagram of an air-conditioning system in a spatial environment in one embodiment. The air-conditioning equipment 200 includes air conditioner 11, air conditioner 12,..., air conditioner 1n, air conditioner 21, air conditioner 22,..., air conditioner 2m. The ambient temperature sensor 300 is set at position T0. The actual outlet air temperature corresponding to air conditioner 11 is T11, the actual outlet air temperature corresponding to air conditioner 12 is T12,..., the actual outlet air temperature corresponding to air conditioner 1n is T1n, the actual outlet air temperature corresponding to air conditioner 21 is T21, the actual outlet air temperature corresponding to air conditioner 22 is T22,..., the actual outlet air temperature corresponding to air conditioner 2m is T2m.

[0026] In a space environment, the control target is the temperature within the space environment. The temperature collected by an ambient temperature sensor 300 at a single detection location, such as at position T0, represents the overall temperature of the space environment. However, space environments often have obstructions such as pillars, which can lead to temperature differences at different locations. This makes the detection location unable to represent the overall temperature of the space environment. In unstable airflow, the temperature measurement at the detection location can fluctuate, causing the air conditioning equipment to constantly adjust, affecting accuracy and equipment life.

[0027] If the prior art priority strategy is used to control the actual ambient temperature collected at the detection location, the following situation may occur: Let's assume that air conditioner 22 has the highest priority, followed by air conditioner 2m. When temperature T0 exceeds the ambient setpoint, air conditioner 22 is prioritized. Even when air conditioner 22 is operating at maximum cooling capacity, T0 still cannot be lowered to the ambient setpoint. In this case, the cooling capacity of air conditioner 2m needs to be increased. However, due to the pillar blocking air conditioner 2m from T0, even if air conditioner 2m is operating at a high cooling capacity, T0 can only be reduced slightly. At this point, the actual temperature in the right side of the room may have already dropped significantly, resulting in energy waste. Furthermore, as the cooling capacity of air conditioner 2m increases, its air volume may also increase, disrupting the original flow field. If the air conditioner is continuously adjusted, the flow field will also fluctuate, causing the temperature value near T0 to constantly change with the fluctuations in the flow field. This, in turn, will exacerbate the adjustment of the air conditioning system. Even if all air conditioners are adjusted synchronously, the above problems will still arise due to differences between units.

[0028] See also Figure 3 , a control method for an air conditioning system provided in an embodiment of the present application, which can be applied to Figure 1 The control device 100 shown includes the following steps:

[0029] S11. Acquire a target environment setting temperature in a target space environment, and acquire an actual environment temperature in the target space environment.

[0030] In this embodiment, the target spatial environment indicates the spatial environment in which each air conditioning device is located, for example, a space consisting of one or more rooms. The target ambient temperature setting indicates the temperature that the user desires the target spatial environment to achieve. An ambient temperature sensor 300 is located at a detection position in the target spatial environment and is used to detect the actual ambient temperature of the target spatial environment. The control device 100 obtains the actual ambient temperature detected by the ambient temperature sensor 300.

[0031] S12. Obtain the current set air outlet temperature configured for the air-conditioning system set in the target space environment; and obtain the actual air outlet temperature of each air-conditioning device in the air-conditioning system, and calculate the current average actual air outlet temperature based on the actual air outlet temperature of each air-conditioning device.

[0032] In this embodiment, the current set outlet temperature is the outlet temperature configured by the control device 100 based on the currently collected data of the target space environment. The current set outlet temperature is used to control each air conditioning device in the target space environment so that each air conditioning device controls its operation based on the current set outlet temperature, thereby ensuring that the actual outlet temperature of each air conditioning device approaches the current set outlet temperature. In one implementation, the actual outlet temperatures of each air conditioning device 200 are accumulated and averaged to obtain the current average actual outlet temperature.

[0033] S13. Obtain a value of a relationship parameter, where the relationship parameter represents a relationship between a change in the average actual air outlet temperature of the air-conditioning system and a change in the actual ambient temperature.

[0034] In an air conditioning system, the actual ambient temperature in a space is related to the average actual outlet air temperature. When the average actual outlet air temperature increases, the actual ambient temperature also increases, and when the average actual outlet air temperature decreases, the actual ambient temperature also decreases. Therefore, the relationship parameter represents the relationship between the average actual outlet air temperature change and the actual ambient temperature change in the air conditioning system. The control device 100 can then dynamically update the current set outlet air temperature based on the value of the relationship parameter and other parameters to ensure that the actual ambient temperature reaches the user's desired target ambient temperature setting.

[0035] S14. Based on the target ambient setting temperature, the actual ambient temperature, the current average actual outlet air temperature and the values ​​of the related parameters, the current set outlet air temperature is adjusted to obtain the adjusted set outlet air temperature, and the outlet air temperature of each air-conditioning device is controlled according to the adjusted set outlet air temperature.

[0036] In this embodiment, after obtaining the target environment setting temperature, the control device 100 will set the current set air outlet temperature, and then each air-conditioning device 200 will control its own operation according to the current set air outlet temperature. Each air-conditioning device 200 can collect its corresponding actual air outlet temperature. The control device 100 calculates the current average actual air outlet temperature based on the actual air outlet temperature collected by each air-conditioning device 200.

[0037] During operation of the air conditioning system, if the current average actual air outlet temperature differs from the current set air outlet temperature, it indicates that the actual ambient temperature in the target space environment has not yet reached the target ambient set temperature, and a compensation adjustment is required for the current set air outlet temperature. If the current average actual air outlet temperature is adjusted to the current set air outlet temperature, the temperature in the space environment should theoretically be adjusted from the actual ambient temperature to the estimated ambient temperature. The estimated ambient temperature can then be calculated based on the relationship parameters. The current set air outlet temperature is then compensated and adjusted based on the difference between the estimated ambient temperature and the target ambient set temperature to obtain the adjusted set air outlet temperature. Prior to the next adjustment cycle, each air conditioning device 200 controls its operation based on the adjusted set air outlet temperature.

[0038] S15. Update the adjusted set air outlet temperature to the current set air outlet temperature, and determine whether the current condition meets the end control condition. If the current condition does not meet the end control condition, return to obtain the target environment set temperature and the actual environment temperature, and update the current set air outlet temperature until the current condition meets the end control condition.

[0039] In this embodiment, in the target space environment, after the user sets the target ambient temperature, the temperature within the target space environment will not immediately reach the target ambient temperature. Multiple adjustment cycles are required to adjust the various air conditioning devices within the air conditioning system so that the temperature within the target space environment gradually stabilizes and remains near the target ambient temperature. Therefore, if the current conditions do not meet the termination control conditions, the above steps S11-S14 are repeated to compensate for the current set air outlet temperature until the termination control conditions are met, at which point the compensation adjustment for the current set air outlet temperature ends. The termination control conditions include, but are not limited to: the air conditioning system is in the startup / shutdown state, the difference between the actual ambient temperature and the target ambient temperature is less than a preset value, the number of adjustments exceeds a preset number, and so on.

[0040] In the above embodiment, the embodiment of the present application obtains the target environment setting temperature under the target space environment, and obtains the actual environment temperature under the target space environment; obtains the current average actual air outlet temperature of the air-conditioning system; obtains the value of the relationship parameter indicating the relationship between the average actual air outlet temperature change of the air-conditioning system and the actual environment temperature change, and can dynamically compensate and adjust the current set air outlet temperature based on the target environment setting temperature, the actual environment temperature, the current average actual air outlet temperature and the value of the relationship parameter. After dynamically adjusting the current set air outlet temperature, each air-conditioning device in the air-conditioning system dynamically adjusts its respective operation to adjust its respective actual air outlet temperature Since each air-conditioning device makes its own adjustments based on the current set air outlet temperature, after dynamic adjustment, the actual air outlet temperature of each air-conditioning device tends to be stable and close to the same value, thereby reducing the temperature measurement value fluctuation caused by the unstable flow field, making the unit run more smoothly and extending the service life of the equipment; and after multiple dynamic adjustments, the temperature in the target space environment gradually tends to be stable and stabilizes near the target environment set temperature, thereby achieving precise control; since after dynamic adjustment, the actual air outlet temperature of each air-conditioning device tends to be stable and close to the same value, it also reduces the unevenness in the space environment, effectively reduces the room temperature difference, and achieves the purpose of energy saving.

[0041] In some embodiments, obtaining a value of a relationship parameter indicating a relationship between a change in the average actual air outlet temperature of the air conditioning system and a change in the actual ambient temperature includes:

[0042] When each test air-conditioning device in the test air-conditioning system located in the test space environment is operating stably, at least one set of test parameter data is obtained, and each set of test parameter data includes: a first average actual test air outlet temperature, a first actual test environment temperature, a second average actual test air outlet temperature and a second actual test environment temperature, wherein the first average actual test air outlet temperature is a value calculated based on the actual test air outlet temperature of each test air-conditioning device under the first air-conditioning system parameters configured according to the air-conditioning system parameters of the test air-conditioning system; the first actual test environment temperature is a temperature value of the test space environment collected under the first air-conditioning system parameters; the second average actual test air outlet temperature is a value calculated based on the actual test air outlet temperature of each test air-conditioning device under the second air-conditioning system parameters configured according to the air-conditioning system parameters of the test air-conditioning system; the second actual test environment temperature is a temperature value of the test space environment collected under the second air-conditioning system parameters; wherein the first air-conditioning system parameters are different from the second air-conditioning system parameters, the first average actual test air outlet temperature is different from the second average actual test air outlet temperature, and the first actual test environment temperature is different from the second actual test environment temperature;

[0043] The value of the relationship parameter is calculated based on at least one set of test parameter data.

[0044] In this embodiment, the value of the relationship parameter can be a fixed value that does not change with other parameters. The value of the relationship parameter can be a value pre-calculated through testing in a test space environment. The test space environment can be a real space environment or a virtual space environment that simulates a real space environment. The test space environment is similar to the target space environment and includes multiple test air conditioning devices, a test controller, and a test environment temperature sensor. Each test air conditioning device corresponds to a test air conditioning temperature sensor. The test environment temperature sensor is used to collect the actual test environment temperature, and the test air conditioning temperature sensor is used to collect the actual test outlet air temperature of the corresponding test air conditioning device. The average actual test outlet air temperature is the value obtained by accumulating and averaging the actual test outlet air temperatures of each test air conditioning device. When obtaining each set of test parameter data, the system parameters of the test air conditioning system are set to the first air conditioning system parameters. When the test air conditioning system is operating stably, a first average actual test outlet air temperature and a first actual test environment temperature are obtained. The system parameters of the test air conditioning system are set to the second air conditioning system parameters. When the test air conditioning system is operating stably, a second average actual test outlet air temperature and a second actual test environment temperature are obtained.

[0045] In order to make the obtained value of the relationship parameter more accurate, multiple sets of test parameter data may be collected and used to calculate the value of the relationship parameter, thereby improving the accuracy of the value of the relationship parameter.

[0046] Optionally, the value of the relationship parameter is obtained based on each group of corresponding test relationship ratios; wherein

[0047]

[0048] T0b represents the second actual test environment temperature, T0a represents the first actual test environment temperature, Txb represents the second average actual test air outlet temperature, and Txa represents the first average actual test air outlet temperature.

[0049] In this embodiment, a test relationship ratio value is obtained for each set of test parameter data. Multiple test relationship ratio values ​​are accumulated and averaged to obtain the value of the relationship parameter. T0b-T0a represents the change in the actual test ambient temperature, and Txb-Txa represents the change in the average actual test outlet air temperature. Therefore, the relationship parameter can reflect the relationship between the actual outlet air temperature of the air conditioning system and the actual ambient temperature in the room environment.

[0050] In the above embodiment, the test air-conditioning system is operated stably in the test air-conditioning environment, and multiple sets of test parameter data are obtained. Then, the value of the relationship parameter is calculated based on the multiple sets of test parameter data, so that a more accurate value of the relationship between the average actual air outlet temperature change of the air-conditioning system and the actual ambient temperature change can be obtained, which is convenient for the subsequent accurate dynamic adjustment of the current set air outlet temperature, thereby reducing the temperature measurement value fluctuation caused by the unstable flow field, making the unit run more smoothly, and extending the service life of the equipment. At the same time, it also realizes precise control and reduces the unevenness in the spatial environment, effectively reducing the temperature difference between the room and achieving the purpose of energy saving.

[0051] In some embodiments, adjusting the current set outlet air temperature based on the target ambient temperature, the actual ambient temperature, the current average actual outlet air temperature, and the value of the relationship parameter to obtain an adjusted set outlet air temperature further includes:

[0052] The current set air outlet temperature is adjusted using a first adjustment formula to obtain an adjusted set air outlet temperature, wherein the first adjustment formula is as follows:

[0053] T xs '=(1-α)Txs+αT x +(T0 s -T0) (1),

[0054] Where T0 s is the target environment temperature, T0 is the actual environment temperature, T x is the current average actual outlet air temperature, α is the relationship parameter, Txs is the current set outlet air temperature, T xs ' is the set outlet air temperature after adjustment.

[0055] In this embodiment, during the operation of the air conditioning system, if the current average actual air outlet temperature of the air conditioning system is controlled by T x becomes Txs, the ambient temperature in the target space environment should change from T0 to the estimated ambient temperature T00. Then, based on the relationship parameters, the estimated ambient temperature in the target space environment can be deduced as:

[0056] T00=T0―α(Tx―Txs) (2),

[0057] Then the difference between the estimated ambient temperature and the target ambient temperature can be calculated, and the current set air outlet temperature can be compensated and adjusted according to the difference between the estimated ambient temperature and the target ambient temperature.

[0058] T xs '=T xs ―(T00―T0 s ) (3),

[0059] According to the above formulas (2) and (3), formula (1) can be derived.

[0060] After obtaining the adjusted set outlet air temperature, each air-conditioning device 200 controls its own operation based on the adjusted set outlet air temperature before the next adjustment cycle arrives. In the next adjustment cycle, the adjusted set outlet air temperature is updated to the current set outlet air temperature, and then the current set outlet air temperature is updated again using formula (1).

[0061] In the above embodiment, when the current average actual outlet air temperature is adjusted to the current set outlet air temperature, the temperature in the space environment should theoretically be adjusted from the actual ambient temperature to the estimated ambient temperature. The estimated ambient temperature can be calculated based on the relationship parameters, and then the current set outlet air temperature is compensated and adjusted based on the difference between the estimated ambient temperature and the target ambient set temperature to obtain the adjusted set outlet air temperature. Then, before the next adjustment cycle arrives, each air-conditioning device controls its own operation based on the adjusted set outlet air temperature. By dynamically adjusting the current set air outlet temperature, each air-conditioning device in the air-conditioning system dynamically adjusts its own operation to adjust its own actual air outlet temperature. Since each air-conditioning device makes its own operation adjustment based on the current set air outlet temperature, after dynamic adjustment, the actual air outlet temperature of each air-conditioning device tends to be stable and close to the same value, thereby reducing the fluctuation of temperature measurement values ​​caused by unstable flow field, making the unit operation more stable and extending the service life of the equipment; and after multiple dynamic adjustments, the temperature in the target space environment gradually tends to be stable and stabilized near the target environment set temperature, thereby also achieving precise control; since after dynamic adjustment, the actual air outlet temperature of each air-conditioning device tends to be stable and close to the same value, it also reduces the unevenness in the space environment, effectively reduces the temperature difference in the room, and achieves the purpose of energy saving.

[0062] In some embodiments, adjusting the current set outlet air temperature based on the target ambient temperature, the actual ambient temperature, the current average actual outlet air temperature, and the value of the relationship parameter to obtain an adjusted set outlet air temperature further includes:

[0063] The current set air outlet temperature is adjusted using a second adjustment formula to obtain an adjusted set air outlet temperature, wherein the second adjustment formula is as follows:

[0064] T xs '=(1-α)Txs+αT x +(T0 s ―T0), where α=f(T x ), (4)

[0065] Where T0 sis the target environment temperature, T0 is the actual environment temperature, T x is the current average actual outlet air temperature, α is the relationship parameter, Txs is the current set outlet air temperature, T xs ' is the set outlet temperature after adjustment, f(T x ) represents the relationship model between the average actual outlet temperature and the relationship parameter. The value of the relationship parameter increases with T x Change and change.

[0066] In this embodiment, the relationship parameter may not be a fixed value, and may change with the average actual air outlet temperature during the operation of the air-conditioning system, wherein the relationship model may be a linear model or a nonlinear model, and multiple sets of sampling data may be obtained by testing in a test environment, and the relationship model may be obtained by fitting based on the multiple sets of sampling data. During the operation of the air-conditioning system, the use of a non-fixed value of the relationship parameter can better reflect the relationship between the change in the average actual air outlet temperature of the air-conditioning system and the change in the actual ambient temperature in the actual environment. The derivation of the second adjustment formula is similar to that of the first adjustment formula, and will not be repeated here. The difference between the second adjustment formula and the first adjustment formula is that the value of the relationship parameter changes with the change in the average actual air outlet temperature.

[0067] When the current average actual air outlet temperature is adjusted to the current set air outlet temperature, the temperature in the space environment should theoretically be adjusted from the actual ambient temperature to the estimated ambient temperature. According to the relationship model, the value of the relationship parameter corresponding to the current average actual air outlet temperature can be obtained. Then, according to the value of the relationship parameter, a more accurate estimated ambient temperature can be calculated. Then, according to the difference between the estimated ambient temperature and the target ambient set temperature, the current set air outlet temperature is compensated and adjusted to obtain the adjusted set air outlet temperature. Then, before the next adjustment cycle arrives, each air-conditioning device controls its own operation based on the adjusted set air outlet temperature.

[0068] In the above embodiment, a non-fixed value of the relationship parameter is adopted, and the value of the relationship parameter is determined based on the current average actual outlet air temperature, so that the current set outlet air temperature can be adjusted more accurately. After multiple dynamic adjustments to the current set outlet air temperature, each air-conditioning device in the air-conditioning system dynamically adjusts its own operation to adjust its own actual outlet air temperature. Since each air-conditioning device makes its own operation adjustment based on the current set outlet air temperature, after dynamic adjustment, the actual outlet air temperature of each air-conditioning device tends to be stable and close to the same value, thereby reducing the temperature measurement value fluctuation caused by the unstable flow field, making the unit run more smoothly and extending the service life of the equipment; and after multiple dynamic adjustments, the temperature in the target space environment gradually tends to be stable and stabilized near the target environment set temperature, thereby also achieving precise control; since after dynamic adjustment, the actual outlet air temperature of each air-conditioning device tends to be stable and close to the same value, thereby reducing the unevenness in the space environment, effectively reducing the room temperature difference, and achieving the purpose of energy saving.

[0069] In some embodiments, obtaining the value of a relationship parameter indicating the relationship between the average actual air outlet temperature change of the air conditioning system and the actual ambient temperature change further includes:

[0070] Obtaining the relationship model;

[0071] The current average actual air outlet temperature is used as the input of the relationship model, and based on the relationship model, the value of the relationship parameter is calculated.

[0072] Optionally, obtaining the relationship model includes:

[0073] When each test air-conditioning device in the test air-conditioning system located in the test space environment is in stable operation, multiple groups of sampling data are respectively obtained, each group of sampling data includes an average actual test air outlet temperature and an actual test environment temperature, and each group of sampling data is collected for different air-conditioning system parameters configured for the test air-conditioning system, wherein the average actual test air outlet temperature corresponding to each group of sampling data is a value calculated from the actual test air outlet temperature of each test air-conditioning device under the air-conditioning system parameters corresponding to each group of sampling data; the actual test environment temperature corresponding to each group of sampling data is a temperature value of the test space environment collected under the air-conditioning system parameters corresponding to each group of sampling data;

[0074] Calculate multiple test ratios based on every two sets of sampling data in the multiple sets of sampling data, where the test ratio represents the ratio of the actual test ambient temperature difference between the two sets of sampling data used to calculate the test ratio and the average actual test air outlet temperature difference;

[0075] The plurality of test ratios are fitted using a fitting method to obtain a relationship model representing the average actual air outlet temperature and the relationship parameter.

[0076] In this embodiment, the test space environment for acquiring multiple sets of sampled data is similar to the test space environment described in the above embodiment, and will not be described in detail here.

[0077] Specifically, the k groups of sample data obtained are (T 01 , T x1 ),(T 02 , T x2 ),…,(T 0i , T xi ),…,(T 0k , T xk ), where T xk represents the average actual test air outlet temperature in the i-th group of sampling data, T 0k The actual test environment temperature in the i-th group of sampled data. Based on each two adjacent groups of data in the k-th group of sampled data, a test ratio is calculated to obtain (k-1) test ratios. Specifically, ΔT 0i =T 0(i+1) ―T 0i ,ΔT xi =T x(i+1) ―T xi , then the (k―1) test ratios are: Based on (k―1) test ratios, the relationship model is fitted using a fitting algorithm, so that the parameters in the relationship model can be obtained, and f(T x ).

[0078] In this embodiment, during the operation of the air conditioning system, if the current average actual air outlet temperature of the air conditioning system is controlled by T x becomes Txs, the ambient temperature in the target space environment should change from T0 to the estimated ambient temperature T00. Then, based on the relationship parameters, the estimated ambient temperature in the target space environment can be deduced as:

[0079]
