A control method of an air conditioner, a control device of an air conditioner, a non-transitory computer-readable storage medium, and an electronic apparatus proposed according to an embodiment of the present application are described below with reference to the drawings.
Fig. 1 is a flowchart of a control method of an air conditioner according to a first embodiment of the present application. As shown in fig. 1, the control method of the air conditioner according to the embodiment of the present application may include the steps of:
s1, acquiring the actual indoor temperature T1Outdoor ambient temperature and indoor actual humidity RH of air conditionerInto
Specifically, the indoor actual temperature T1 may be obtained by an online capacity detection system of the air conditioner, and the indoor actual humidity RH may be obtained by obtaining the return air humidity of the air conditionerIntoSpecifically, the humidity RH of the air entering the indoor heat exchanger can be acquired through a humidity sensor arranged at an air return opening of the indoor heat exchangeraAnd by the formula RHInto=c*d*RHaCalculating the actual indoor humidity RH of the air conditionerIntoWherein c is a preset correction parameter, d is the humidity RH of the air at the air return inlet of the indoor heat exchangeraAnd c and d can be calibrated according to actual conditions.
S2, according to the actual indoor temperature T1And the actual indoor humidity RHIntoAnd calculating to obtain the moisture content in the chamber.
Specifically, the indoor actual temperature T1And the actual indoor humidity RHIntoHas a certain relation with the indoor moisture content and the indoor actual temperature T1And the indoor actual humidity RH of the air conditionerIntoThe corresponding relation between the indoor humidity content and the indoor humidity content can be stored in the air conditioner in advance in a form of a table and can be determined according to the actual indoor temperatureDegree T1And the actual indoor humidity RHIntoWhen moisture content in the chamber is obtained. For example, when the current temperature in the room is 26 ℃ and the current humidity in the room is 60%, the moisture content in the room can be obtained as 12.8g/kg by the table.
S3, if the indoor moisture content is larger than the preset comfortable moisture content threshold, according to the outdoor environment temperature and the indoor actual humidity RHIntoAnd acquiring a corresponding operation mode and indoor set temperature from the cloud platform, and controlling the air conditioner to operate in the operation mode.
S4, according to the actual indoor temperature T1And calculating to obtain a target capacity output value W 'and a target dehumidification value M' of the air conditioner according to the indoor set temperature and the indoor moisture content.
Further, according to the actual indoor temperature T1The method comprises the following steps of calculating a target capacity output value W 'and a target dehumidification value M' of the air conditioner according to indoor set temperature and indoor moisture content, wherein the target capacity output value W 'and the target dehumidification value M' comprise: acquiring operating parameters of the air conditioner according to the indoor actual temperature, the indoor set temperature and the indoor moisture content; controlling the air conditioner to operate for a preset time according to the operation parameters; and acquiring a target capacity output value W 'and a target dehumidification value M' of the air conditioner according to the moisture content and enthalpy diagram corresponding to the indoor set temperature and the human body comfortable temperature.
Specifically, the comfortable humidity corresponding to the comfortable temperature of the human body is 12.8g/kg, so the preset comfortable moisture content threshold value can be 12.8 g/kg. According to the actual indoor temperature T1And the actual indoor humidity RHIntoCalculating indoor moisture content, judging whether the indoor moisture content is lower than 12.8g/kg, if so, exiting the rapid dehumidification mode, and if not, according to the indoor actual temperature T1And calculating to obtain a target capacity output value W 'and a target dehumidification value M' of the air conditioner according to the indoor set temperature and the indoor moisture content.
In practical applications, the indoor temperature is divided into x temperature intervals (typically, the length of the temperature interval may be 2 ℃), for example, the applicable temperature range of the indoor temperature is divided into-20 to 40 ℃ into temperature intervals (-20, -18), temperature intervals (-18, -16), …, temperature intervals (38, 40), similarly, the outdoor temperature is divided into y temperature intervals (typically, the length of the temperature interval may be 5 ℃), and the indoor humidity is divided into z humidity intervals (typically, the length of the humidity interval may be 2%).
The operation parameters of the air conditioners corresponding to different parameter intervals (including the temperature interval of the indoor temperature, the temperature interval of the outdoor temperature and the humidity interval of the indoor humidity) are different, so that multiple groups of operation parameters of the air conditioners can be stored in the air conditioners in advance, and the operation parameters of each group of air conditioners have corresponding relations with the temperature interval of the indoor temperature, the temperature interval of the outdoor temperature and the humidity interval of the indoor humidity.
When the air conditioner operates in a refrigeration mode, if the indoor moisture content is judged to be greater than or equal to the preset moisture content, the corresponding operating parameters of the air conditioner, which are prestored in the air conditioner, are called according to the indoor current temperature, the outdoor current temperature and the indoor current humidity so as to control the air conditioner to operate for a period of time according to the operating parameters, namely, in the initial operating state of the air conditioner, the corresponding operating parameters of the air conditioner are selected based on the indoor current temperature, the outdoor current temperature and the indoor current humidity, and the air conditioner is controlled to operate for a period of time according to the operating parameters. At this time, according to the moisture content corresponding to the user set temperature and the human body comfortable temperature and according to the corresponding enthalpy diagram, the operation capacity and the total dehumidification capacity of the air conditioner which enable the indoor temperature and the indoor moisture content to meet the user requirements can be obtained, and therefore the target capacity output value W 'and the target dehumidification value M' of the air conditioner at each moment can be obtained.
For example, when the current indoor temperature is 35 ℃, the current outdoor temperature is 35 ℃, the indoor humidity is 65%, and the user-set temperature is 26 ℃, it may be determined that the current indoor temperature is within a temperature range (34, 36), the current outdoor temperature is within a temperature range (30, 35), and the indoor humidity is within a humidity range (64%, 66%), so that the operation parameters of the air conditioner (including the operating frequency, the opening degree, and the like of the air conditioner) corresponding to the above-mentioned ranges may be called, and the air conditioner may be controlled to pre-operate for a period of time according to the operation parameters. At this time, according to the user-set temperature (i.e., 26 ℃) and the upper limit (i.e., 12.8g/kg) of the indoor moisture content when the indoor temperature reaches 26 ℃, and according to the corresponding psychrometric chart, the operation capacity and the total dehumidification amount of the air conditioner, in which the indoor temperature reaches 26 ℃ and the indoor moisture content is 12.8g/kg or less, can be acquired, and thereby, the target capacity output value W 'and the target dehumidification value M' of the air conditioner at each time can be acquired.
And S5, acquiring the actual capacity output value W of the air conditioner, and calculating the actual dehumidification value M of the air conditioner according to the actual capacity output value W.
Specifically, the current actual output quantity of the air conditioner (i.e., the actual operation capacity of the air conditioner) can be calculated according to the current temperature, pressure and other parameters of the air conditioner. For example, the machine learning model may be utilized to learn parameters such as the current temperature and pressure of the air conditioner, so as to obtain the current actual output W of the air conditioner.

Specifically, currently, when an air conditioner with a dehumidification function operates in a cooling mode, the dehumidification phase of the air conditioner for rapid cooling is generally controlled based on the change of the indoor and outdoor ambient temperatures or the humidity of the return air area of the air conditioner. However, the indoor and outdoor ambient temperatures change with the change of the operation capacity of the air conditioner, and thus the dehumidification phase of the air conditioner cannot be accurately controlled by the above method.
In the embodiment of the application, the actual indoor temperature, the actual outdoor environment temperature and the actual indoor humidity of the air conditioner are obtained, then calculating to obtain the indoor moisture content according to the indoor actual temperature and the indoor actual humidity, if the indoor moisture content is larger than the preset comfortable moisture content threshold value, acquiring a corresponding operation mode and an indoor set temperature from the cloud platform according to the outdoor environment temperature and the indoor actual humidity, controlling the air conditioner to operate in the operation mode, calculating to obtain target capacity output value and target dehumidification value of the air conditioner according to the indoor actual temperature, indoor set temperature and indoor moisture content, then obtaining the actual capacity output value of the air conditioner, and calculating an actual dehumidification value of the air conditioner according to the actual capacity output value, and finally controlling the air conditioner according to the target capacity output value, the target dehumidification value, the actual capacity output value and the actual dehumidification value. Therefore, the target capacity output value, the target dehumidification value, the actual capacity output value and the actual dehumidification value of the air conditioner can be obtained in real time, the current operation capacity of the air conditioner can be accurately judged, corresponding adjustment is timely carried out on the operation parameters of the air conditioner based on the operation capacity, and therefore corresponding control is accurately and effectively carried out on the dehumidification stage of the air conditioner, the requirements of a user are met, and the comfort level of the user is greatly improved.
It should be noted that, after the air conditioner is turned on, when a user sets a cooling temperature and a corresponding windshield (the windshield may include a plurality of windshields, for example, may include four, a strong gear, a high gear, a medium gear, and a low gear) to control the air conditioner to operate in the cooling mode, the network connection state of the air conditioner needs to be confirmed before acquiring the current indoor temperature, the outlet air temperature of the air conditioner, and the actual indoor humidity. If the air conditioner can be connected to the cloud platform, the operating parameters of the air conditioner are correspondingly adjusted according to data stored in a database of the cloud platform (the initial value of the data can be derived from factory settings of the air conditioner, and the data can be updated according to operating parameters set when other users use the air conditioners of the same model to ensure the effectiveness of the data), so as to meet the requirements of the users; if the air conditioner cannot be connected to the cloud platform, the current air conditioner is judged to be in an offline mode, the air conditioner is controlled to operate in the offline mode, meanwhile, the indoor and outdoor ambient temperature and humidity of the air conditioner are collected, the current indoor and outdoor ambient temperature and the current indoor ambient humidity are recorded into a storage unit of the air conditioner, and whether the storage unit of the air conditioner stores the last-time operation data or not is confirmed. If the storage unit of the air conditioner stores the data of the last operation, controlling the air conditioner to operate according to the data of the last operation; if the storage unit of the air conditioner has no data of the last operation, the air conditioner needs to be controlled to reenter the cooling and dehumidifying mode and correspondingly adjust the operation parameters of the air conditioner according to the humidity condition, namely, the air conditioner is correspondingly controlled according to the target capacity output value, the target dehumidifying value, the actual capacity output value and the actual dehumidifying value of the air conditioner. The data of the air conditioner local machine can be updated through a big data platform or remotely and manually updated so as to ensure the validity of the data and control the storage capacity of the air conditioner.
That is, when the air conditioner can be connected to the cloud platform, the air conditioner is controlled correspondingly directly according to the data stored in the database of the cloud platform, so as to meet the requirements of users; when the air conditioner cannot be connected to the cloud platform, the air conditioner is controlled to operate in an off-line mode, data of the last operation are stored in a storage unit of the air conditioner, the air conditioner is controlled to operate according to the data of the last operation, and when the data of the last operation do not exist in the storage unit, the air conditioner is correspondingly controlled through the calculated data of the target capacity output value, the target dehumidification value, the actual capacity output value, the actual dehumidification value and the like of the air conditioner, so that the air conditioner can be effectively controlled under the condition that the air conditioner cannot be connected to a network, and the requirements of users are met.
On the basis of the above embodiments, an embodiment of the present application proposes a method for controlling an air conditioner according to a target capacity output value W ', a target dehumidification value M', and an actual capacity output value westhmically dehumidified amount M. As shown in fig. 3, the method may include the steps of:
s501, obtaining a first difference value of subtracting the target capacity output value from the actual capacity output value, and generating a first state value of the air conditioner according to the first difference value.
According to an embodiment of the present application, generating the first state value of the air conditioner according to the first difference may specifically include: judging whether the first difference is greater than or equal to a first preset threshold value, and if the first difference is greater than or equal to the first preset threshold value, setting the first state value as a first value; and if the first state value is smaller than the first preset threshold value, setting the first state value as a second value. Wherein the second value is greater than the first value.
Specifically, after the actual capacity output value W and the target capacity output value W ' of the air conditioner are acquired, a difference between the actual capacity output value W and the target capacity output value W ' of the air conditioner, that is, a first difference Δ W (i.e., Δ W — W '), may be calculated. And judging whether the operation capacity of the air conditioner meets a preset scheme or not according to the first difference value delta W and the first preset threshold value, and generating a corresponding first state value u, wherein the first state value u can comprise a first value and a second value. If the first difference value Δ W is greater than or equal to a first preset threshold value, it indicates that the operation capability of the air conditioner meets a preset scheme, and at this time, the first state value u may be set to a first value; if the first difference value Δ W is smaller than the first preset threshold, it indicates that the operation capability of the air conditioner cannot meet the preset scheme, and at this time, the first state value u may be set to the second value.
For example, the first predetermined threshold may be 0, the first value may be 0, and the second value may be 1. If the first difference value delta W is greater than or equal to 0, the actual capacity output value W of the air conditioner is greater than or equal to the target capacity output value W', the operation capacity of the air conditioner meets a preset scheme, and at the moment, the first state value u can be set to be 0; if the first difference Δ W is smaller than 0, it indicates that the actual capacity output value W of the air conditioner is smaller than the target capacity output value W', and the operation capacity of the air conditioner cannot meet the preset scheme, at this time, the first state value u may be set to 1.
And S502, calculating a second difference value obtained by subtracting the actual dehumidification value from the target dehumidification value, and generating a second state value of the air conditioner according to the second difference value.
According to an embodiment of the present application, generating the second state value of the air conditioner according to the second difference may specifically include: judging whether the second difference value is within a first preset range, and if the second difference value is within the first preset range, setting the second state value as the first value; the second state value is set to a third value if the second difference is not within the first preset range, the third value being greater than the second value.
Specifically, after the actual dehumidification value M and the target dehumidification value M ' of the air conditioner are acquired, a difference between the target dehumidification value M ' and the actual dehumidification value M, that is, a second difference Δ M (that is, Δ M ═ M ' -M) may be calculated. And judging whether the dehumidification amount of the air conditioner meets the operation requirement of the current air conditioner according to the second difference value delta M, and generating a corresponding second state value v, wherein the second state value v can comprise a first value and a third value. If the second difference value Δ M is within a first preset range (the first preset range can be calibrated according to the model of the air conditioner, the external environment and other actual conditions), it indicates that the deviation between the actual dehumidification value M and the target dehumidification value M' is small, the dehumidification capacity of the air conditioner meets the current operation requirement of the air conditioner, and at this time, the second state value v can be set as the first value; if the second difference Δ M is not within the first preset range, it indicates that the deviation between the actual dehumidification value M and the target dehumidification value M' is large, and the dehumidification amount of the air conditioner cannot meet the operation requirement of the current air conditioner, and at this time, the second state value v may be set to a third value.
For example, the first preset range may be e-M to e + M, the first value is 0 and the second value is 2, and whether the amount of dehumidification of the air conditioner satisfies the current operation requirement of the air conditioner is determined by determining whether the second difference Δ M is within the first preset range, i.e., whether | Δ M-e | is less than or equal to M. If the second difference value Δ M is within the first preset range, namely, the | Δ M-e | is not more than M, it indicates that the deviation between the actual dehumidification value M and the target dehumidification value M' is small, the dehumidification capacity of the air conditioner meets the operation requirement of the current air conditioner, and at this time, the second state value v can be set to be 0; if the second difference value Δ M is not within the first preset range, that is, Δ M-e | M, it indicates that the deviation between the actual dehumidification value M and the target dehumidification value M' is large, and the dehumidification amount of the air conditioner cannot meet the operation requirement of the current air conditioner, at this time, the second state value v may be set to 2.
And S503, calculating the sum of the first state value and the second state value to obtain the total state value of the air conditioner.
As one possible implementation, the total state value N of the air conditioner may be a sum of the first state value u and the second state value v, i.e., N ═ u + v. For example, when the first state value u is set to 0 and the second state value v is set to 0, the total state value N of the air conditioner may be 0; when the first state value u is set to 1 and the second state value v is set to 0, the total state value N of the air conditioner may be 1; when the first state value u is set to 0 and the second state value v is set to 2, the total state value N of the air conditioner may be 2; when the first state value u is set to 1 and the second state value v is set to 2, the total state value N of the air conditioner may be 3.
And S504, controlling the air conditioner according to the total state value of the air conditioner.
According to an embodiment of the present application, controlling the air conditioner according to the total state value of the air conditioner may specifically include: if the total state value is in the first range, keeping the operation parameters of the air conditioner unchanged; if the total state value is in the second range, adjusting the air output of the air conditioner, and/or the working frequency of a compressor of the air conditioner, and/or the opening degree of an electronic expansion valve of the air conditioner by the first amplitude; if the total state value is in the third range, adjusting the working frequency of the air conditioner according to the actual capacity output value and the target capacity output value, and reducing the air output of the air conditioner; and if the total state value is in the fourth range, adjusting the air output of the air conditioner and/or the working frequency of a compressor of the air conditioner and/or the opening degree of an electronic expansion valve of the air conditioner by a second amplitude, wherein the second amplitude is larger than the first amplitude.
As one possible implementation manner, as the total state value of the air conditioner increases, the control process of the air conditioner may be sequentially divided into four stages, i.e., a first stage, a second stage, a third stage, and a fourth stage. The current operation state of the air conditioner can be obtained according to the size of the total state value of the air conditioner (or the stage of the control process of the air conditioner), and the operation parameters of the air conditioner can be correspondingly adjusted according to the operation state, namely the air conditioner is correspondingly controlled.
If the total state value is in the first range (namely, the control process of the air conditioner is in the first stage), the running state of the air conditioner is good, and therefore, the running parameters of the air conditioner can be kept unchanged; if the total state value is in the second range (namely, the control process of the air conditioner is in the second stage), the dehumidification amount of the air conditioner meets the operation requirement of the current air conditioner, but the overall operation capacity of the air conditioner cannot meet the preset scheme, so that the air output amount of the air conditioner and the working frequency of a compressor can be improved in a small range by combining the dehumidification amount of the air conditioner, or the electronic expansion valve is adjusted according to the specific condition of the air conditioner; if the total state value is in the third range (namely, the control process of the air conditioner is in the third stage), the fact that the overall operation capacity of the air conditioner meets the preset scheme is indicated, but the dehumidification capacity of the air conditioner cannot meet the operation requirement of the current air conditioner, therefore, the working frequency of the air conditioner can be adjusted by combining the overall operation capacity of the air conditioner, and the air output capacity of the air conditioner is reduced; if the total state value is in the fourth range (i.e. the control process of the air conditioner is in the fourth stage), it indicates that the overall operation capacity of the air conditioner cannot meet the preset scheme, and the dehumidification capacity of the air conditioner cannot meet the current operation requirement of the air conditioner, so that the air output capacity of the air conditioner and the operating frequency of the compressor need to be greatly increased, or the electronic expansion valve needs to be adjusted according to the specific conditions of the air conditioner.
For example, if the total state value of the air conditioner is 0, i.e. the first state value u is set to 0, and the second state value v is set to 0, it indicates that the operation state of the air conditioner is good, and therefore, no adjustment is required to the operation parameters of the air conditioner.
If the total state value of the air conditioner is 1, namely the first state value u is set to 1, and the second state value v is set to 0, it is indicated that the dehumidification amount of the air conditioner meets the operation requirement of the current air conditioner, but the overall operation capacity of the air conditioner cannot meet the preset scheme, so that the air output amount of the air conditioner and the working frequency of a compressor can be improved to a small extent by combining the dehumidification amount of the air conditioner, or the opening degree of an electronic expansion valve can be adjusted according to the specific situation of the air conditioner.
When the total state value of the air conditioner is 1, the operation parameters of the air conditioner can be correspondingly adjusted according to the table 1 and the magnitude of the first difference value Δ W.
TABLE 1
For example, when the damper set by the user is the damper 1, the opening degree of the air conditioner is the opening degree 1, the operating frequency is the frequency 1, and the angle is the angle 1. At this time, if the total state value of the air conditioner is 1 and the first difference Δ W is small, the operation parameters of the air conditioner may be correspondingly adjusted according to the correction 1, that is, the opening degree of the air conditioner is adjusted to 11, the operating frequency is adjusted to 11, and the angle is adjusted to 11; if the total state value of the air conditioner is 1 and the first difference Δ W is large, the operation parameters of the air conditioner may be correspondingly adjusted according to the correction 2, that is, the opening degree of the air conditioner is adjusted to 12, the operating frequency is adjusted to 12, and the angle is adjusted to 12.
If the total state value of the air conditioner is 2, namely the first state value u is set to be 0, and the second state value v is set to be 2, the whole operation capacity of the air conditioner meets the preset scheme, but the dehumidification capacity of the air conditioner cannot meet the operation requirement of the current air conditioner, so that the working frequency of the air conditioner can be adjusted by combining the whole operation capacity of the air conditioner, and the air output capacity of the air conditioner is reduced.
If the total state value of the air conditioner is 3, that is, the first state value u is set to 1, and the second state value v is set to 2, it indicates that the overall operation capacity of the air conditioner cannot meet the preset scheme, and the dehumidification capacity of the air conditioner cannot meet the operation requirement of the current air conditioner, so that the air output capacity of the air conditioner and the working frequency of the compressor need to be greatly increased, or the opening degree of the electronic expansion valve needs to be adjusted according to the specific conditions of the air conditioner.
When the total state value of the air conditioner is 2 or 3, the operation parameters of the air conditioner can be correspondingly adjusted according to the table 2 and the magnitude of the first difference value Δ W.
TABLE 2
For example, when the windshield set by the user is the windshield 1, the opening degree of the air conditioner is the opening degree 5, the operating frequency is the frequency 5, and the angle is the angle 5. At this time, if the total state value of the air conditioner is 2 or 3 and the deviation between the actual dehumidification value and the target dehumidification value of the air conditioner is small, the operation parameters of the air conditioner can be correspondingly adjusted according to the correction 3, that is, the opening of the air conditioner is adjusted to be 51, the working frequency is adjusted to be 51, and the angle is adjusted to be 51; if the total state value of the air conditioner is 2 or 3 and the deviation between the actual dehumidification value and the target dehumidification value of the air conditioner is large, the operation parameters of the air conditioner can be correspondingly adjusted according to the correction 4, namely, the opening of the air conditioner is adjusted to be 52, the working frequency is adjusted to be 52, and the angle is adjusted to be 52.
Therefore, the actual operation state and the adjustable parameters of the air conditioner are combined, the operation parameters of the air conditioner are correspondingly adjusted according to the different operation states, the actual capacity output value W and the target capacity output value W 'of the air conditioner, the actual dehumidification value M and the target dehumidification value M', so that the dehumidification capacity and the operation capacity of the air conditioner meet the requirements of a user, the indoor humidity can be accurately controlled, and the user experience is greatly improved.
Further, after the operation parameters of the air conditioner are correspondingly adjusted, the actual capacity output value W and the target capacity output value W 'and the actual dehumidification value M and the target dehumidification value M' are detected again at intervals of first preset time so as to accurately and effectively control the dehumidification rate of the air conditioner, intermittently detect the indoor humidity, and convert the indoor humidity into the corresponding indoor moisture content. When the indoor moisture content is less than or equal to the upper limit of the indoor moisture content corresponding to the comfortable temperature of the human body, the user can be prompted that the current humidity is comfortable, and whether the current humidity of the user is appropriate or not can be inquired, for example, inquiry information can be displayed through a touch display screen of an air conditioner so as to inquire whether the current humidity of the user is appropriate or not. If the user selects that the current humidity is proper, controlling the air conditioner to exit the current cooling and dehumidifying mode; and if the current humidity selected by the user is not suitable, controlling the air conditioner to continuously operate in the current cooling and dehumidifying mode, and continuously inquiring whether the current humidity of the user is suitable or not until the indoor humidity meets the requirement of the user. Therefore, the indoor humidity can be accurately and effectively controlled, so that the humidity meets the requirements of users, and the experience of the users is greatly improved.
It should be noted that, in the process that the air conditioner operates in the cooling mode, the operation habit of the user may be recorded, and the operation habit of the user is uploaded to the cloud platform, or the operation habit of the user is entered into the air conditioner (for example, a storage module may be added to the air conditioner to enter the operation habit of the user into the storage module, or the operation habit of the user may be directly entered into an existing chip of the air conditioner), so that when the air conditioner is controlled next time, corresponding data is directly called to control the air conditioner.
