For a better understanding of the above technical solutions, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
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 T1Indoor set temperature, outdoor ambient temperature and indoor actual humidity RH of the air conditioner.
Specifically, the indoor actual temperature T1 may be acquired by an online capability detection system of the air conditioner. Indoor actual humidity RH can be obtained by obtaining return air humidity of 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 conditionerIntoAnd the indoor moisture content can be stored in the air conditioner in advance in the form of a table according to the actual indoor temperature 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 value, according to the outdoor environment temperature, the indoor set temperature and the indoor actual humidity RHIntoAnd acquiring corresponding operating parameters from the cloud platform, and controlling the air conditioner to operate according to the operating parameters.
S4, according to the actual indoor temperature T1And calculating to obtain the target capacity output value W' of the air conditioner according to the indoor set temperature and the indoor moisture content.
Further, in the present invention, the calculating the target capacity output value of the air conditioner according to the indoor actual temperature, the indoor set temperature and the indoor moisture content may include: 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 operating parameters; and acquiring a target capacity output value of the air conditioner according to the moisture content and the 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 the target capacity output value W' 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 humidity of the indoor humidity, so that the air conditioner is controlled to operate in advance 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 humidity of the indoor humidity, and the air conditioner is controlled to operate in advance 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 psychrometric chart, the operation capacity of the air conditioner which enables both the indoor temperature and the indoor moisture content to meet the user requirement can be obtained, and therefore, the target capacity output value W' 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 capacity of the air conditioner, which allows the indoor temperature to reach 26 ℃ and the indoor moisture content to be 12.8g/kg or less, can be acquired, and thereby, the target capacity output value W' of the air conditioner at each time can be acquired.
And S5, acquiring the actual capacity output value W and the outlet air temperature T' of the air conditioner.
Specifically, the air conditioner can be controlled according to the current temperature, pressure and other parameters of the air conditionerThe current actual output quantity of the air conditioner (i.e., the actual operation capacity of the air conditioner) is calculated. 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. The temperature T at the air outlet of the indoor heat exchanger can be obtained through a temperature sensor arranged at a certain position of the air outlet of the indoor heat exchanger (for example, a buckling position of a guide blade strip arranged at the center of the air outlet)aAnd by the formula T' ═ a × b × TaCalculating the temperature T' of the air outlet dry bulb, namely the air outlet temperature of the air conditioner, wherein a is a preset correction parameter, and b is the temperature T at the air outlet of the indoor heat exchangeraAnd (3) relevant temperature correction parameters, and a and b can be calibrated according to actual conditions.
S6, according to the target ability output value W', the actual ability output value W and the indoor actual temperature T1And the air outlet temperature T' controls 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, acquire indoor actual temperature, indoor settlement temperature, the indoor actual humidity of outdoor ambient temperature and air conditioner, then according to indoor actual temperature and indoor actual humidity, calculate and obtain the indoor moisture content, if the indoor moisture content is greater than preset comfortable moisture content threshold value, then according to outdoor ambient temperature, indoor settlement temperature and indoor actual humidity, acquire corresponding operating parameter from the cloud platform, and control the air conditioner and move according to operating parameter, according to indoor actual temperature, indoor settlement temperature and indoor moisture content, calculate the target capacity output value that obtains the air conditioner, acquire the actual capacity output value and the air-out temperature of air conditioner again, and according to target capacity output value, actual capacity output value, indoor actual temperature and air-out temperature, it is right the air conditioner controls. Therefore, the target capacity output value and the actual capacity output 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 the dehumidification stage of the air conditioner is accurately and effectively controlled correspondingly, the requirements of users are met, and the comfort level of the users 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 actual capacity output value and the like 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.
