These drawings and written description are not intended to limit the scope of the disclosed concept in any way, but to illustrate the disclosed concept for those skilled in the art by referring to specific embodiments.

Detailed ways

In order to make the purposes, 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 in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

Before introducing the embodiments of this application, first explain the application scenarios of the embodiments of this application:

Air conditioning refers to equipment that uses manual means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. For household air conditioners, it usually includes compressors, air conditioner fans, condensers, evaporators, four-way valves, one-way valve capillary components and other parts. Wherein, the air conditioner fans include indoor fans and outdoor fans. As the core of the refrigeration system, the compressor absorbs the heat from one end of the low-pressure zone into the refrigerant and then sends it to the high-pressure zone, and uses the outdoor fan to dissipate the heat in the refrigerant to the air to regulate the temperature. Accurate control of the air conditioner can improve the comfort and sense of use of the user when using the air conditioner, thereby increasing the popularity of the air conditioner brand. Therefore, how to realize the precise control of the air conditioner is very important.

In the prior art, the air conditioner is mainly controlled according to the outdoor ambient temperature. Specifically, in the cooling mode, the outdoor ambient temperature may be acquired, and the operating frequency of the compressor may be controlled according to the outdoor ambient temperature. When the outdoor ambient temperature is high, the compressor is controlled to run at a high frequency; when the outdoor ambient temperature is low, the compressor is controlled to run at a low frequency. Thus, the compressor can work according to the operating frequency, continuously absorb the heat in the room, and reduce the indoor ambient temperature to the temperature preset by the user.

However, in the above solution, when the outdoor ambient temperature is low and the indoor ambient temperature is high, if the user eats hot pot indoors, the indoor ambient temperature will gradually rise because the hot pot will emit a large amount of heat. However, due to the low outdoor ambient temperature, the operating frequency of the compressor is low, so that the cooling output of the indoor unit cannot meet the indoor cooling demand, resulting in low accuracy of air conditioning control.

In view of the above problems, the inventive concept of the present application is as follows: when controlling the air conditioner, the output cooling capacity of the air conditioner cannot guarantee to meet the demand for cooling capacity of the indoor environment, resulting in low control accuracy of the air conditioner. Based on this, the inventor found that when the indoor environment has a large demand for cooling capacity and the outdoor ambient temperature is low, the current operating frequency of the compressor is corrected according to the corrected frequency, so that the compressor is controlled according to the corrected operating frequency. Carry out work, just can solve the problem that the control accuracy of air-conditioning is lower in the prior art.

Exemplarily, the air conditioner control method provided in the embodiment of the present application may be applied to a schematic diagram of an application scenario shown in FIG. 1 . FIG. 1 is a schematic diagram of an application scenario of an air conditioner control method provided by an embodiment of the present application, so as to solve the above technical problems. As shown in Figure 1, the application scenario may include: air conditioners and servers.

Exemplarily, in the application scenario shown in FIG. 1 , the air conditioner needs to obtain the outdoor ambient temperature, the indoor ambient temperature, and the operating frequency of the compressor of the air conditioner through corresponding sensors. After the air conditioner acquires the outdoor ambient temperature, the indoor ambient temperature, and the operating frequency of the compressor, they can also be sent to the server for subsequent processing.

In this embodiment, after receiving the outdoor ambient temperature, indoor ambient temperature, and operating frequency of the compressor sent by the air conditioner, the server can execute the program code of the control method of the air conditioner, so as to control the compressor of the air conditioner to perform Work.

In practical applications, since terminal devices (such as mobile phones, computers, etc.) and air conditioners are also processing devices with data processing capabilities, the server in the application scenario shown in Figure 1 above can also be implemented by terminal devices or air conditioners. In the embodiments of the present application, the server, the terminal device for data processing, and the air conditioner may be collectively referred to as an air conditioner control device.

Wherein, the executor of the embodiment of the present application is the control device of the air conditioner.

Below, the technical solution of the present application will be described in detail through specific embodiments.

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 repeated in some embodiments.

Fig. 2 is a schematic flowchart of Embodiment 1 of the air conditioner control method provided by the embodiment of the present application. As shown in Figure 2, the control method of the air conditioner may include the following steps:

In a possible implementation manner, the control device of the air conditioner may obtain the target operating frequency according to the formula (1): F′=F+ΔF. Among them, F' is the target operating frequency, F is the operating frequency of the compressor, and ΔF is the corrected frequency.

In this possible implementation, the correction frequency can be set according to the outdoor ambient temperature. For example, when the outdoor ambient temperature is less than or equal to 20°C, the correction frequency is 15Hz; when the outdoor ambient temperature is less than or equal to 25°C and greater than 20 ℃, the correction frequency is 20Hz.

In another possible implementation, the control device of the air conditioner can obtain the target operating frequency of the compressor according to the indoor ambient temperature, the operating frequency of the compressor, the indoor temperature threshold, and the correction frequency, so as to control the compressor to operate at the target operating frequency .

Wherein, the control device of the air conditioner can obtain the target operating frequency according to the formula (2): F'=F+(Tin-T _s )×ΔF. Among them, F′ is the target operating frequency, F is the operating frequency of the compressor, Tin is the indoor ambient temperature, T _s is the indoor temperature threshold, and ΔF is the correction frequency.

In this possible implementation manner, the correction frequency may be a preset frequency, such as 3 Hz, 4 Hz, 5 Hz, etc., and may be set according to actual conditions, which is not specifically limited in this embodiment of the present application.

Wherein, the temperature information includes an outdoor ambient temperature where the air conditioner is located and an indoor ambient temperature. The air-conditioning control equipment controls the operation of the compressor by processing the operating frequency of the compressor and the preset correction frequency, which can generate enough cooling capacity for the indoor environment, effectively improving the accuracy of air-conditioning control, thereby further ensuring It improves the user's experience of using the air conditioner.

Therefore, the speed of the outdoor fan of the air conditioner is also required, so that the outdoor fan can be subsequently processed according to the speed of the outdoor fan.

Optionally, the control device of the air conditioner may acquire the rotational speed of the outdoor fan of the air conditioner through a corresponding sensor.

S202: Control the outdoor fan to work according to the speed of the outdoor fan and the preset corrected 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, according to the acquired rotational speed of the outdoor fan and the preset corrected rotational speed, the The outdoor fan is controlled.

In a specific implementation manner, the control device of the air conditioner can obtain the target rotational speed according to the formula (3): R′=R+ΔR. Among them, R' is the target speed, R is the speed of the outdoor fan, and ΔR is the corrected speed.

In this possible implementation, the corrected rotational speed can be set according to the outdoor ambient temperature. For example, when the outdoor ambient temperature is less than or equal to 20°C, the corrected rotational speed is 100 rpm; when the outdoor ambient temperature is less than or equal to 25°C and greater than 20 ℃, the correction speed is 200rpm.

In another possible implementation, the air conditioner control device can correct the speed according to the indoor ambient temperature, the speed of the outdoor fan, and the indoor temperature threshold, and obtain the target speed of the outdoor fan, so as to control the outdoor fan to work at the target speed.

Wherein, the control device of the air conditioner can obtain the target operating speed according to the formula (4): R′=R+(Tin−T _s )×ΔR. Among them, R′ is the target running speed, R is the running speed of the compressor, Tin is the indoor ambient temperature, T _s is the indoor temperature threshold, and ΔR is the corrected speed.

In this possible implementation manner, the corrected rotational speed may be set according to the outdoor ambient temperature. Exemplarily, for example, when the outdoor ambient temperature is less than or equal to 20°C, the corrected rotational speed is 20 rpm; when the outdoor ambient temperature is less than or equal to 25°C and greater than 20°C, the corrected rotational speed is 30 rpm.

Therefore, in order to further improve the accuracy of the control of the air conditioner, various functions may be pre-set for the air conditioner, such as a low-temperature cooling enhancement function, a cooling function, a heating function, and the like. When the air conditioner turns on 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 another specific implementation manner, the control device of the air conditioner may acquire the start instruction sent by the remote controller matched with the air conditioner. Exemplarily, after turning on the refrigeration function, the user may press the "mode" and "power" buttons on the remote controller for a certain period of time. The pressing time may be 1s, 2s, 3s, etc., and may be set according to actual conditions, which is not limited in this embodiment of the present application. After the remote control acquires the user's pressing operations on the "mode" and "power" buttons, it sends an opening instruction to the control device of the air conditioner, and the control device of the air conditioner receives the opening instruction sent by the remote control.

S302: Turn on the low-temperature refrigeration enhancement function according to the turn-on instruction.

In this step, after receiving the start instruction, the control device of the air conditioner will turn on the low-temperature refrigeration enhancement function, and execute the method in the first embodiment.

Optionally, after the low-temperature refrigeration enhancement function is turned on, the refrigeration function will not be cleared, that is, the protection function in the refrigeration function can still operate normally.

If the cooling enhancement function is switched to other functions of the air conditioner, the low-temperature cooling enhancement function will be turned off.

Wherein, the control device of the air conditioner can obtain the closing instruction and/or switching instruction sent by the terminal equipment connected to the air conditioner, and can also obtain the closing instruction and/or switching instruction sent by the remote controller matched with the air conditioner. In practical applications, The closing instruction and/or switching instruction may also be obtained through other means, which is not specifically limited in this embodiment of the present application.

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 low-temperature cooling enhancement function is turned on again.

Exemplarily, after the low-temperature refrigeration enhancement function is in the state to be turned on, the temperature information, the operating frequency of the compressor of the air conditioner, and the rotational speed of the outdoor fan can be acquired according to a preset acquisition frequency. The preset acquisition frequency can be 1h, 2h, 3h, etc., and can be set according to actual needs, which is not specifically limited in this embodiment of the present application.

Wherein, if the control device of the air conditioner obtains an off instruction or obtains a switch instruction, the low-temperature cooling enhancement function is turned off, and the temperature and cooling enhancement function can be turned on again only after the air conditioner control device obtains an activation instruction again.

In the control method of the air conditioner provided in the embodiment of the present application, the control device of the air conditioner acquires an activation instruction, and activates the low-temperature refrigeration enhancement function according to the activation instruction. The control device of the air conditioner activates the low-temperature refrigeration enhancement function according to the activation command, which can effectively prevent the false triggering of the control of the air conditioner in winter or in some other special weather, thereby further improving the accuracy of the control of the air conditioner.
