Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Before introducing the embodiments of the present application, an application scenario of the embodiments of the present application is explained first:
air conditioning refers to a device that adjusts and controls parameters such as temperature, humidity, and flow rate of ambient air inside a building or structure by manual means. For household air conditioners, it is common to include a compressor, an air conditioner fan, a condenser, an evaporator, a four-way valve, a one-way valve capillary tube assembly, and the like. The air conditioner fan comprises an indoor fan and an outdoor fan. The compressor is used as the core of the refrigerating system, heat at one end of the low-pressure area is absorbed into the refrigerant and then sent to the high-pressure area, and the heat in the refrigerant is radiated into the air by the outdoor fan, so that the air temperature is regulated. The air conditioner is accurately controlled, so that the comfort level and the use feeling of a user using the air conditioner can be improved, and the popularity of the brand of the air conditioner is further improved. Therefore, it is important how to achieve precise control of the air conditioner.
In the prior art, the air conditioner is mainly controlled according to the outdoor environment temperature. Specifically, in the cooling mode, the outdoor ambient temperature may be obtained, and the operating frequency of the compressor may be controlled according to the outdoor ambient temperature. When the outdoor environment temperature is higher, controlling the compressor to operate at a higher frequency; when the outdoor environment temperature is low, the compressor is controlled to operate at a lower frequency. Therefore, the compressor can work according to the running frequency, continuously absorbs indoor heat, and reduces the indoor environment temperature to the temperature preset by a user.
However, in the above scheme, when the outdoor environment temperature is low and the indoor environment temperature is high, if a user eats a hot pot indoors, the indoor environment temperature gradually rises due to a large amount of heat emitted by the hot pot. However, the running frequency of the compressor is low due to low outdoor environment temperature, so that the cold output of the indoor unit cannot meet the indoor cold requirement, and the accuracy of air conditioner control is low.
In view of the above problems, the inventive concept of the present application is as follows: when the air conditioner is controlled, the cold quantity output by the air conditioner cannot be guaranteed to meet the requirement of indoor environment on the cold quantity, so that the control accuracy of the air conditioner is low. Based on this, the inventor finds that, under the condition that the indoor environment has a large requirement on the cooling capacity and the outdoor environment has a low temperature, the current operation frequency of the compressor is corrected according to the correction frequency, so that the compressor is controlled to work according to the corrected operation frequency, and the problem that the control accuracy of the air conditioner in the prior art is low can be solved.
For example, the control method of the air conditioner provided by the embodiment of the present application may be applied to an application scenario diagram shown in fig. 1. Fig. 1 is a schematic view of an application scenario of a control method of an air conditioner according to an embodiment of the present application, so as to solve the above technical problem. As shown in fig. 1, the application scenario may include: air conditioners and servers.
For example, in the application scenario shown in fig. 1, the air conditioner needs to obtain, through corresponding sensors, an outdoor ambient temperature and an indoor ambient temperature at which the air conditioner is located, and an operating frequency of a compressor of the air conditioner. The air conditioner can also send the outdoor ambient temperature, the indoor ambient temperature and the running frequency of the compressor to a server so as to carry out subsequent processing.
In this embodiment, after receiving the outdoor ambient temperature, the indoor ambient temperature and the operating frequency of the compressor of the air conditioner sent by the air conditioner, the server may execute the program code of the control method of the air conditioner, so as to control the compressor of the air conditioner to operate.
In practical applications, since a terminal device (such as a mobile phone, a computer, etc.) and an air conditioner are also processing devices with data processing capability, the server in the application scenario shown in fig. 1 can also be implemented as the terminal device or the air conditioner. In the embodiment of the present application, the server, the terminal device for data processing, and the air conditioner may be collectively referred to as a control device of the air conditioner.
The execution main body of the embodiment of the application is control equipment of an air conditioner.
The technical solution of the present application will be described in detail below with reference to specific examples.
It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a schematic flowchart of a first embodiment of a control method of an air conditioner according to an embodiment of the present application. As shown in fig. 2, the control method of the air conditioner may include the steps of:
s101: temperature information and an operating frequency of a compressor of the air conditioner are acquired.
In this step, in order to improve the accuracy of controlling the air conditioner, it is necessary to obtain the temperature information and the operating frequency of the compressor of the air conditioner so as to process the information later.
The temperature information includes an outdoor ambient temperature and an indoor ambient temperature at which the air conditioner is located.
In a possible implementation manner, the control device of the air conditioner may obtain the outdoor ambient temperature and the indoor ambient temperature where the air conditioner is located, and the operating frequency of the compressor of the air conditioner through corresponding sensors.
S102: and if the outdoor environment temperature is less than or equal to the preset outdoor temperature threshold and the indoor environment temperature is greater than or equal to the preset indoor temperature threshold, controlling the compressor to work according to the running frequency of the compressor and the preset correction frequency.
In this step, because in the prior art, under the condition that the outdoor environment temperature where the air conditioner is located is low but the indoor environment temperature is high, the cold output by the air conditioner cannot meet the requirement of the indoor environment, under this condition, the compressor of the air conditioner needs to be further controlled, so as to improve the accuracy of controlling the air conditioner.
When the outdoor environment temperature is less than or equal to the preset outdoor temperature threshold and the indoor environment temperature is greater than or equal to the preset indoor temperature threshold, the control equipment of the air conditioner further processes the compressor of the air conditioner.
Optionally, in order to further improve the accuracy of the control, a temperature range may be further set, and when the outdoor ambient temperature is less than or equal to the preset outdoor temperature threshold, the indoor ambient temperature is greater than or equal to the preset indoor temperature threshold, and a difference obtained by subtracting the indoor temperature threshold from the indoor ambient temperature is not within the temperature range, the control device of the air conditioner further processes the compressor of the air conditioner.
In one possible implementation, the control device of the air conditioner may be according to formula (1): and F' ═ F + delta F is used for acquiring the target operating frequency. Wherein, F' is the target operation frequency, F is the operation frequency of the compressor, and Δ F is the correction frequency.
In this possible implementation, the correction frequency may be set according to the outdoor ambient temperature, e.g., when the outdoor ambient temperature is less than or equal to 20 ℃, the correction frequency is 15 Hz; when the outdoor environment temperature is less than or equal to 25 ℃ and greater than 20 ℃, the correction frequency is 20 Hz.
In another possible implementation manner, the control device of the air conditioner may obtain the target operation frequency of the compressor according to the indoor ambient temperature, the operation frequency of the compressor, the indoor temperature threshold, and the correction frequency, so as to control the compressor to operate according to the target operation frequency.
Wherein the control apparatus of the air conditioner may be according to formula (2): f' ═ F + (Tin-T)s) And acquiring the target operating frequency by multiplying the frequency by the delta F. Wherein F' is a target operating frequency, F is an operating frequency of the compressor, Tin is an indoor ambient temperature, and T issIs the indoor temperature threshold, and Δ F is the correction frequency.
In this possible implementation manner, the correction frequency may be a preset frequency, may be 3Hz, may also be 4Hz, 5Hz, and the like, and may be set according to an actual situation, which is not specifically limited in the embodiment of the present application.
In the control method of the air conditioner provided by the embodiment of the application, the operation of the compressor is controlled according to the operation frequency of the compressor and the preset correction frequency by acquiring the temperature information and the operation frequency of the compressor of the air conditioner, and if the outdoor environment temperature is less than or equal to the preset outdoor temperature threshold and the indoor environment temperature is greater than or equal to the preset indoor temperature threshold. The temperature information includes an outdoor ambient temperature and an indoor ambient temperature at which the air conditioner is located. The control device of the air conditioner processes the running frequency of the compressor and the preset correction frequency, so that the compressor is controlled to work, sufficient cold quantity can be generated for indoor environment, the accuracy of air conditioner control is effectively improved, and the feeling of using the air conditioner by a user is further guaranteed.
On the basis of the foregoing embodiments, fig. 3 is a flowchart illustrating a second embodiment of a control method of an air conditioner according to an embodiment of the present application. As shown in fig. 3, when the outdoor ambient temperature is less than or equal to the preset outdoor temperature threshold and the indoor ambient temperature is greater than or equal to the preset indoor temperature threshold, the control method of the air conditioner may further include the steps of:
s201: and acquiring the rotating speed of an outdoor fan of the air conditioner.
In this step, the outdoor fan may be further controlled, so as to improve the accuracy of controlling the air conditioner, and therefore, the rotation speed of the outdoor fan of the air conditioner is also required, so as to facilitate the subsequent processing of the outdoor fan according to the rotation speed of the outdoor fan.
Optionally, the control device of the air conditioner may obtain the rotation speed of the outdoor fan of the air conditioner through a corresponding sensor.
S202: and controlling the outdoor fan to work according to the rotating speed of the outdoor fan and the preset correction rotating speed.
In this step, when the outdoor ambient temperature is less than or equal to the preset outdoor temperature threshold and the indoor ambient temperature is greater than or equal to the preset indoor temperature threshold, the outdoor fan may be controlled according to the obtained rotation speed of the outdoor fan and the preset correction rotation speed.
In a specific implementation, the control device of the air conditioner may be according to formula (3): and R ═ R + Δ R to obtain a target rotating speed. Wherein R' is the target rotating speed, R is the rotating speed of the outdoor fan, and Delta R is the corrected rotating speed.
In this possible implementation, the correction rotation speed may be set according to the outdoor environment temperature, for example, when the outdoor environment temperature is less than or equal to 20 ℃, the correction rotation speed is 100 rpm; when the outdoor environment temperature is less than or equal to 25 ℃ and greater than 20 ℃, the correction rotating speed is 200 rpm.
In another possible implementation manner, the control device of the air conditioner may obtain the target rotation speed of the outdoor fan according to the indoor ambient temperature, the rotation speed of the outdoor fan, the indoor temperature threshold, and the corrected rotation speed, so as to control the outdoor fan to operate at the target rotation speed.
Wherein the control apparatus of the air conditioner may be according to formula (4): r' ═ R + (Tin-T)s) And acquiring the target running rotating speed by multiplying the multiplied by delta R. Wherein R' is a target operation rotation speed, R is an operation rotation speed of the compressor, Tin is an indoor environment temperature, and T issIs the indoor temperature threshold, and Δ R is the corrected rotational speed.
In this possible implementation, the correction rotational speed may be set according to the outdoor ambient temperature. Illustratively, when the outdoor ambient temperature is less than or equal to 20 ℃, the correction rotation speed is 20 rpm; when the outdoor environment temperature is less than or equal to 25 ℃ and greater than 20 ℃, the correction rotating speed is 30 rpm.
In the control method of the air conditioner provided by the embodiment of the application, when the outdoor environment temperature is less than or equal to the preset outdoor temperature threshold and the indoor environment temperature is greater than or equal to the preset indoor temperature threshold, the outdoor fan is controlled to work by acquiring the rotating speed of the outdoor fan of the air conditioner and according to the rotating speed of the outdoor fan and the preset correction rotating speed. The control equipment of the air conditioner controls the outdoor fan to work by processing the acquired rotating speed of the outdoor fan and the preset correction rotating speed, so that the heat of the indoor environment can be more accurately discharged outdoors, and the accuracy of air conditioner control is further improved.
On the basis of any of the above embodiments, fig. 4 is a schematic flow chart of a third embodiment of a control method of an air conditioner provided in the embodiment of the present application. As shown in fig. 4, before S101, the method for controlling an air conditioner may further include the steps of:
s301: and acquiring a starting instruction.
In this step, since in winter or some other special weather, although the outdoor ambient temperature is less than or equal to the preset outdoor temperature threshold and the indoor ambient temperature is greater than or equal to the preset indoor temperature threshold, the air conditioner is not required to perform cooling at this time. Therefore, in order to further improve the accuracy of the control of the air conditioner, various functions, such as a low-temperature cooling enhancement function, a cooling function, a heating function, etc., may be provided in advance for the air conditioner. When the air conditioner starts the low-temperature refrigeration enhancement function, the control device of the air conditioner executes the method in the first embodiment.
Wherein the start command is used to start the low temperature refrigeration enhancement function.
In a specific embodiment, the control device of the air conditioner may obtain a turn-on instruction sent by a terminal device connected with the air conditioner. For example, when the low-temperature refrigeration enhancement function needs to be started, a user can click an application program in a mobile phone connected with the air conditioner, the mobile phone generates a starting instruction by responding to the operation of the user, and sends the starting instruction to a control device of the air conditioner, and the control device of the air conditioner receives the starting instruction sent by the mobile phone.
In another specific embodiment, the control device of the air conditioner may obtain an opening instruction sent by a remote controller matched with the air conditioner. For example, after the cooling function is turned on, the user may press the "mode" and "power" keys in the remote controller for a certain pressing time. The pressing time may be 1s, 2s, 3s, etc., and may be set according to actual conditions, which is not limited in the embodiments of the present application. The remote controller sends an opening instruction to the control device of the air conditioner after acquiring the pressing operation of the mode key and the powerful key by the user, and the control device of the air conditioner receives the opening instruction sent by the remote controller.
S302: and starting the low-temperature refrigeration enhancement function according to the starting instruction.
In this step, after receiving the start command, the control device of the air conditioner starts the low-temperature refrigeration enhancement function, and executes the method in the first embodiment.
Optionally, after the low-temperature refrigeration enhancement function is started, the refrigeration function is not cleared, that is, the protection function in the refrigeration function can still operate normally.
Further, if the outdoor ambient temperature is greater than the outdoor temperature threshold, or the indoor ambient temperature is less than the indoor temperature threshold, or a closing instruction is obtained, the closing instruction is used for closing the low-temperature refrigeration enhancement function, or a switching instruction is obtained, the switching instruction is used for closing the low-temperature refrigeration enhancement function and switching to other functions of the air conditioner, and then the low-temperature refrigeration enhancement function is closed.
The control device of the air conditioner may obtain a closing instruction and/or a switching instruction sent by a terminal device connected to the air conditioner, may also obtain a closing instruction and/or a switching instruction sent by a remote controller matched with the air conditioner, and in practical application, may also obtain a closing instruction and/or a switching instruction through other approaches, which is not specifically limited in this embodiment of the present application.
