The air conditioning equipment comprises an air conditioner internal unit and an air conditioner external unit, the air conditioner internal unit and the air conditioner external unit have certain energy consumption, and the energy consumption of the air conditioning equipment is large due to the consumption of the internal unit and the external unit. The energy consumption can be understood as the power consumption of the air conditioning equipment, and the air conditioning equipment with low energy consumption has less power consumption in the process of achieving the same refrigeration effect.
At present, the control method of the air conditioning equipment is to control the air conditioning equipment to reduce the temperature of the air conditioning equipment to the temperature required by a user as soon as possible, and the energy consumption problem of the air conditioning equipment is not considered in the control process.
In view of this, the present embodiment provides an air conditioning equipment control method, and the flow of the method is described in detail below with reference to fig. 1.
and 103, controlling the air conditioning equipment according to the parameters in the first control parameters.
The method shown in fig. 1 is performed by an air conditioning system control device. The air conditioning equipment control device can be realized by a controller, the controller can be arranged in the air conditioning equipment, the controller can also be equipment which is arranged relatively independently from the air conditioning equipment, and the relative independence means that no direct mechanical connection exists between the controller and the air conditioning equipment. Specifically, the controller may be implemented in many ways, such as a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present Application, such as one or more microprocessors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs).
The air conditioner control device may be implemented by a server or a terminal device. Fig. 2 shows an application scenario of the embodiment of the present application. In this application scenario, the air conditioner control device is taken as an example of a server. The server is connected with the air conditioning equipment through the communication device, the air conditioning equipment sends data to the server, and the server sends corresponding control signals to the air conditioning equipment, so that the air conditioning equipment operates according to the received control signals. The communication device may be implemented by chip modules disposed in the server and the air conditioning equipment, the communication mode provided by the communication device includes a cellular mobile communication mode or short-range Wireless communication, the cellular mobile communication mode includes a 4G network or a 5G network, the short-range Wireless communication includes Wireless Fidelity (WIFI), bluetooth, and the like, and the communication device may implement communication between the two, and the specific implementation form of the communication device is not limited herein. The server may be a virtual server or a physical server, and is not particularly limited herein. The air conditioning equipment herein refers to a variable frequency air conditioner. The inverter air conditioner means that the running frequency of a compressor of the air conditioning equipment is variable.
The following description will take an application scenario as shown in fig. 2 as an example when the air conditioning equipment control method in the embodiment of the present application is applied.
In the process of controlling the operation of the air conditioning equipment, the air conditioning equipment control device needs to first obtain the corresponding operating parameters of the air conditioning equipment, that is, execute step 101, that is, obtain the first operating parameters of the air conditioning equipment and the environmental parameters of the environment where the air conditioning equipment is located.
Specifically, the first operating parameter includes an ambient temperature set by a user and an electrical parameter of the air conditioning equipment. The ambient temperature set by the user is also the temperature of the air conditioning equipment set by the user. The electrical parameters of the air-conditioning equipment include an operating current of the air-conditioning equipment, an operating voltage of the air-conditioning equipment, and the like. The environmental parameters of the environment in which the air conditioning equipment is located include the ambient temperature, the ambient humidity, and the like.
The air conditioning equipment control device can directly acquire and obtain the electrical parameters of the air conditioning equipment through an electrical sensor on the air conditioning equipment. Similarly, the air conditioner control device may obtain the environmental parameters of the environment in which the air conditioner is located according to a temperature sensor, a humidity sensor, and the like on the air conditioner. The air-conditioning apparatus control device acquires the ambient temperature set by the user in the first operation parameter of the air-conditioning apparatus as follows.
The first mode is that the air conditioning equipment control device receives an operation instruction sent by a user and acquires the environmental temperature set by the user of the air conditioning equipment according to the operation instruction.
Specifically, when the user needs to adjust the temperature of the air conditioner, the user may send an operation instruction to the air conditioner control device. The user may send the operation instruction through a remote controller of the air conditioner control device, or the user may directly perform the operation through a touch key of the air conditioner control device, and the specific manner in which the user sends the operation instruction is not limited herein. The user sends an operation command, which corresponds to the air conditioning equipment control device receiving the operation command. The air conditioning equipment control device analyzes the operation command to obtain the environmental temperature set by the user.
For example, the user inputs 24 ℃ on the remote controller of the air conditioning equipment control device, the air conditioning control device receives the operation command of the user through the remote controller, and analyzes the operation command, so that the air conditioning control device obtains the environment temperature set by the user as 24 ℃ according to the operation command.
After the air conditioner control device obtains the first operating parameter of the air conditioner and the environmental parameter of the environment where the air conditioner is located, the air conditioner control device executes step 102, that is, determines the first control parameter corresponding to the first operating parameter and the environmental parameter.
Specifically, the first control parameter of the air conditioning equipment comprises the rotating speed of a fan, the running frequency of a compressor and the opening degree of an electronic expansion valve. The fan rotation speed refers to the rotation speed of a fan in air conditioning equipment in unit time, and generally takes the rotation/minute (r/min) as a unit. The compressor operating frequency refers to an operating frequency of a compressor in an air conditioning apparatus, and is generally in hertz (Hz). The opening degree of the electronic expansion valve is generally adjusted by a stepping motor, the minimum angle range of the rotation of the stepping motor becomes one step, and the opening degree of the electronic expansion valve is generally in units of step (b). Of course, the first control parameter may also include other operating parameters of the air conditioning equipment, and is not limited herein.
In the embodiment of the present application, M correspondence relationships are stored in the air conditioning equipment control device in advance, and the M correspondence relationships can be understood as relationships between multiple sets of control parameters and corresponding energy consumptions of the air conditioning equipment under different operating parameters and different environmental parameters. It should be noted that the parameters included in each set of control parameters are the same as the parameters included in the first control parameters, for example, the fan speed, the compressor operation frequency, the opening degree of the electronic expansion valve, and the like are also included in each set of control parameters. Because the energy consumption of the air-conditioning equipment under different control parameters may be different, in order to reduce the energy consumption of the air-conditioning equipment, the air-conditioning equipment control device determines the first control parameter according to the M corresponding relationships after acquiring the first control parameter and the environmental parameter of the air-conditioning equipment. The first control parameter in the embodiment of the present application may be understood as that, when the air conditioner control device uses the first control parameter to control the operation of the air conditioner, the energy consumption of the air conditioner is lower than a preset threshold, where the preset threshold may be set by a technician, or may be automatically configured by the air conditioner control device according to an actual use condition, which is not limited herein.
In the embodiment of the present application, the air conditioning equipment control device determines the first control parameter in the following manner.
And determining N corresponding relations matched with the first operation parameters and the environmental parameters of the air conditioning equipment from the M corresponding relations, and obtaining first control parameters according to the N corresponding relations, wherein M is an integer larger than or equal to 1, and N is a positive integer smaller than or equal to M.
Specifically, when M is equal to N, the M correspondences may be understood as relationships between different sets of control parameters and corresponding energy consumptions of the air conditioning equipment under the first operating parameter and the environmental parameter. However, in order to expand the control range of the air conditioner control device, generally M is larger than N, and M corresponding relationships can be understood as relationships between different sets of control parameters and corresponding energy consumptions of the air conditioners under the conditions of different operating parameters and different environmental parameters of the air conditioners. The air conditioning equipment corresponds to different operating parameters and different environmental parameters and has corresponding relationships, the air conditioning equipment control device needs to obtain corresponding relationships of a first operating parameter and an environmental parameter from the M corresponding relationships, and the obtained corresponding relationships are N corresponding relationships. The set of control parameters may refer to the content of the first control parameter discussed above, and will not be described herein. A method of the air conditioner control device obtaining the M correspondence relationships will be explained below as an example.
One way to obtain M correspondences is for the air conditioning equipment control device to obtain M correspondences through neural network training. Specifically, the air conditioning equipment control device obtains operating parameters and environmental parameters of the air conditioning equipment under different control parameters, inputs the operating parameters and the environmental parameters into an input layer of the neural network, obtains energy consumption corresponding to the operating parameters and the environmental parameters according to the operating parameters and the environmental parameters, establishes a model between the operating parameters and the environmental parameters and the energy consumption of the air conditioning equipment, and continuously adjusts unknown parameters in the model according to the energy consumption, so that a plurality of models are obtained, and the models can be understood as corresponding relations between M energy consumption and M control parameters. The specific process of training the model using the neural network is referred to in the art and will not be described in detail herein. According to the embodiment of the application, through neural network training, more accurate corresponding relation can be obtained, and the improvement of the precision of controlling the air conditioning equipment is facilitated.
One way to obtain M correspondence relationships is for an air conditioning equipment control device to adjust values of control parameters according to a preset rule when the air conditioning equipment is in different operating parameters and different environmental parameters, to obtain M sets of control parameters and M energy consumptions, to establish a one-to-one correspondence relationship between the M sets of control parameters and the M energy consumptions under different operating parameters and different environmental parameters, to obtain M correspondence relationships. In the embodiment of the application, the air conditioner control device adjusts the control parameters according to the preset rules, so that the data processing process of the air conditioner control device is simplified, and the energy consumption of the air conditioner control device can be relatively reduced.
Specifically, the M groups of control parameters are different M groups of control parameters, and the control parameters may refer to the discussion of the first control parameter, which is not described herein again. The different control parameters mean that at least one of the fan rotating speed, the compressor operating frequency and the opening degree of the electronic expansion valve of any two groups of control parameters is different.
The preset rule may be preset by the air conditioner control device. The preset rule is, for example, a preset decreasing rule or a preset increasing rule. The preset decreasing rule means that the air conditioning equipment control device decreases the value of the control parameter according to the preset value gradient. Sequentially decreasing the control parameter may be understood as sequentially decreasing one of the control parameters, or may be sequentially decreasing a plurality of parameters. The preset value may be one value, or three parameters in the control parameters may have one preset value, and the number of the preset values is not limited herein. The size of the preset value may be set by the air conditioner control device by default, and the size of the preset value is not specifically limited herein. The preset adding rule means that the air conditioning equipment control device sequentially increases the values of the control parameters according to the preset value. The default values and the contents sequentially increasing may refer to the contents sequentially decreasing discussed above, and are not described herein again.
The air conditioning equipment control device controls the air conditioning equipment to operate under different control parameters, and the air conditioning equipment control device can obtain different energy consumptions corresponding to the air conditioning equipment. The energy consumption of the air conditioner obtained by the air conditioner control device may be represented by various methods, such as the power consumption of the air conditioner, the power of the air conditioner, and the like. If the power of the air conditioning equipment is used to represent the energy consumption of the air conditioning equipment, the energy consumption P of the air conditioning equipment may be represented as P UI, and if the power consumption of the air conditioning equipment is used to represent the energy consumption of the air conditioning equipment, the energy consumption P of the air conditioning equipment may be represented as P UI t/1000, and t represents the time (in hours) during which the air conditioning equipment is operated. For the sake of simplifying the calculation, the power of the air conditioner is taken as an example to represent the energy consumption of the air conditioner.
The air conditioning equipment control device obtains different control parameters by adjusting a preset rule, and the air conditioning equipment control device can correspondingly obtain a plurality of energy consumptions. The air conditioning equipment control device may obtain energy consumption corresponding to a set of control parameters after obtaining the set of control parameters, or the air conditioning equipment control device may obtain M energy consumptions after obtaining M sets of control parameters.
The following describes a process of obtaining M sets of control parameters, taking N corresponding relationships between the first operating parameter and the environmental parameter as an example.
The first way to obtain the N control parameters is to please refer to fig. 3, and the air conditioning equipment control device obtains the first energy consumption of the air conditioning equipment in the first operating parameter and the environmental parameter when the value of the control parameter is the initial value. And adjusting the value of the control parameter according to a preset decreasing rule to obtain the adjusted control parameter. Alternatively, the air conditioner control device may also adjust the control parameter according to a preset increasing rule to obtain the adjusted control parameter, and the air conditioner control device adjusts the control parameter according to the preset decreasing rule is described as an example herein. And under the adjusted control parameters, the air conditioning equipment control device obtains second energy consumption of the air conditioning equipment in the first operation parameters and the environmental parameters, if the second energy consumption is lower than the first energy consumption, values of the adjusted control parameters are sequentially reduced according to a preset decreasing rule to obtain N groups of control parameters, and if the second energy consumption is higher than the first energy consumption, values of the adjusted control parameters are sequentially reduced according to the preset decreasing rule to obtain N groups of control parameters.
Specifically, the control parameter has an initial value, and the initial value may be set by the air conditioner control device by default, or directly set as the initial value by the current control parameter of the air conditioner for the convenience of processing by the air conditioner control device. The air conditioning equipment control device obtains first energy consumption of the air conditioning equipment under the initial value. And the air conditioning equipment control device adjusts the initial value, obtains the adjusted control parameter and obtains the second energy consumption of the air conditioning equipment under the adjusted control parameter. The air conditioning equipment control device determines the relation between the first energy consumption and the second energy consumption, so that the air conditioning equipment control device is determined to adjust parameters according to a preset decreasing rule or a preset increasing rule, and then N groups of control parameters are obtained according to the determined preset rule. The "first" and "second" of the "first energy consumption" and the "second energy consumption" are only used for distinguishing energy consumption under different sets of control parameters, and the specific size of the energy consumption is not limited.
For example, the air conditioner control device obtains the environmental temperature of 24 ℃, the environmental temperature of 24 ℃ and the environmental humidity of 50% set by the user, and controls the parameter a (the fan rotation speed is 1000r/min, the compressor operation frequency is 90Hz, and the opening of the electronic expansion valve is 120 b).
The air conditioning equipment control device adjusts the value of the control parameter A according to a preset decreasing rule to obtain a control parameter B (the rotating speed of a fan is 990r/min, the operating frequency of a compressor is 80Hz, and the opening degree of an electronic expansion valve is 110B), the air conditioning equipment operates under the control parameter B, and under the condition of the control parameter B, the air conditioning equipment control device can obtain that the electrical parameter of the air conditioning equipment is specifically a current value of 6.8A and a voltage value of 380V. The air conditioning equipment control device calculates the energy consumption B of the air conditioning equipment as P-UI-380-6.8-2584W.
The air conditioning equipment control device determines the energy consumption size relation corresponding to the control parameter A and the control parameter B, and determines that the first energy consumption is larger than the second energy consumption, and the first energy consumption is larger than the second energy consumption, which indicates that the energy consumption of the air conditioning equipment can be reduced according to a preset decreasing rule. The air conditioner control device obtains N sets of control parameters as shown in table 1 below in sequence according to a preset decreasing rule. In order to reduce the amount of memory occupied by the control parameters, the air conditioning equipment control device may omit and store the units corresponding to the respective parameters.

After the air conditioning equipment control device obtains the N sets of control parameters, the air conditioning equipment control device may obtain N energy consumptions according to the N sets of control parameters, and the process of obtaining the N energy consumptions may refer to the process of calculating the energy consumption corresponding to the control parameter a in the foregoing. The obtained N sets of corresponding parameters and N energy consumptions are shown in table 2 below.

Or, the air conditioning equipment control device may obtain M energy consumptions corresponding to the M sets of control parameters after obtaining the M sets of control parameters.

For example, the relationship between M energy consumptions and M sets of control parameters may be represented by one function, and the climate control device may accordingly establish only one functional relationship. The form of the corresponding relationship may be a table, a text, a functional relationship, etc., and the form of the corresponding relationship is not limited herein.
In order to facilitate the air-conditioning equipment control device to distinguish the relationship between the data and the operation parameters and the environmental parameters, the air-conditioning equipment control device can save the relationship between each corresponding relationship and the operation parameters and the environmental parameters in the air-conditioning equipment control device while obtaining the corresponding relationship, or the air-conditioning equipment control device directly takes the operation parameters and the environmental parameters as indexes when storing the corresponding relationship, so that the air-conditioning equipment control device can conveniently call the corresponding relationship to control the air-conditioning equipment at the later stage.
For example, according to the M sets of control parameters and M energy consumptions in table 2 above, M correspondences obtained are shown in table 3 below.
TABLE 3
| Control parameter | Energy consumption |
| 1000-90-120 | 3344W |
| 990-80-110 | 2584W |
| 980-70-100 | 2470W |
| 970-60-90 | 2351W |
| 1000-90-120 | 2298W |
| 990-80-110 | 2198W |

After the air conditioning equipment control device obtains the M corresponding relations, the N corresponding relations matched with the first operation parameters and the environmental parameters of the air conditioning equipment are determined from the M corresponding relations. The M corresponding relationships include different operating parameters and different environmental parameters, and the matching may be understood as screening out the corresponding relationship between the first operating parameter and the environmental parameter.
For example, the first operating parameter and the environmental parameter are 24-380-8.8-24-50%. Referring to table 3, there are 3 corresponding 6 correspondences with the first operating parameter and the environmental parameter, and there are 4 corresponding N correspondences, as shown in table 4 below.
TABLE 4
And after the air conditioning equipment control device determines the matched N corresponding relations, obtaining a first control parameter according to the N corresponding relations. The following describes a manner in which the air conditioning equipment control device obtains the first control parameter according to the N correspondence relationships.
A mode for obtaining the first control parameter according to the N corresponding relations is that K corresponding relations corresponding to the condition that the energy consumption of the air conditioning equipment in the N corresponding relations is lower than a preset threshold value are determined in the N corresponding relations, and one group of control parameters in any one corresponding relation in the K corresponding relations are determined to be the first control parameter, wherein K is a positive integer smaller than or equal to N.
Specifically, the number of N correspondences may be one or more. The preset threshold may be set by the air conditioner control device as a default, and the size of the preset threshold may be arbitrary, and the size of the preset threshold is not specifically limited herein. The air conditioning equipment control device determines K corresponding relations of which the energy consumption is lower than a preset threshold value in the N corresponding relations, and the number of the K corresponding relations can be one or multiple. When the number of the corresponding relations is one, the air conditioning equipment directly takes the control parameter in the corresponding relation as the first control parameter. When the number of the correspondence relationships is greater than or equal to two, the air conditioning equipment control device may randomly select one correspondence relationship among the K correspondence relationships, and use the control parameter in the correspondence relationship as the first control parameter.
For example, referring to table 4 above, the preset threshold is 2500W. The air conditioner control device can screen out 2 correspondences among the 4 correspondences in table 4, as shown in table 5 below.
TABLE 5
| Control parameter | Energy consumption |
| 980-70-100 | 2470W |
| 970-60-90 | 2351W |
Then, the air conditioning equipment control device randomly selects any one set of correspondence in table 5, and takes the corresponding control parameter as the first control parameter. For example, the air conditioning equipment control device selects 980-70-100 of the correspondence relationships in the first column as the first control parameter.
Or to further reduce the energy consumption of the air conditioning apparatus. One way to obtain the first control parameter according to the N corresponding relationships is to determine a first corresponding relationship corresponding to the minimum value of the energy consumption from the N corresponding relationships, and determine a group of control parameters in the first corresponding relationship as the first control parameter.
Specifically, in the N corresponding relationships, the energy consumption corresponding to each corresponding relationship is different, the air conditioning equipment control device directly determines the minimum corresponding relationship of the energy consumption as the first corresponding relationship, and determines the control parameter corresponding to the first corresponding relationship as the first control parameter.
For example, the air conditioning equipment control device obtains K correspondence relationships shown in table 4, and determines that the minimum energy consumption is 2351W, thereby determining control parameters 970 to 60 to 90 corresponding to the energy consumption as first control parameters.
After the air-conditioning apparatus control device obtains the first control parameter, the air-conditioning apparatus may be controlled according to the first control parameter. For example, after the air conditioning equipment control device obtains that the first control parameter of the air conditioning equipment is 970-60-90, the air conditioning equipment control device can directly adjust the rotating speed of a fan of the air conditioning equipment to 970r/min, the running frequency of a compressor to 60Hz and the opening degree of an electronic expansion valve to 90 b. Thereby enabling the air conditioning equipment to achieve better energy-saving effect.
In the embodiment of the application, the air conditioning equipment control device acquires a first operating parameter and an environmental parameter of the air conditioning equipment, then matches a first control parameter with which the energy consumption is lower than a preset threshold value and which is matched with the parameter, and controls the air conditioning equipment to operate by using the first control parameter. On one hand, the method can reduce energy consumption of the air conditioning equipment in the operation process, and on the other hand, the air conditioning equipment control device can directly determine the operation parameters of all parts of the air conditioning equipment, so that the air conditioning equipment can be accurately controlled.
