[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The following describes a method for controlling an air conditioner, a control device for an air conditioner, a computer-readable storage medium, and an air conditioner according to embodiments of the present invention with reference to the accompanying drawings.

[0034] Figure 1 is a flow chart of a method for controlling an air conditioner according to some embodiments of the present invention.

[0035] like Figure 1As shown, the control method of the air conditioner according to the embodiment of the present invention may include the following steps:

[0036] S1, in response to an instruction to enter a heating energy-saving mode, the heating energy-saving mode includes multiple operation stages.

[0037] S2, determining the operating frequencies corresponding to the multiple operating stages.

[0038] S3, controlling the air conditioner according to the operating frequency corresponding to each operating stage.

[0039] Specifically, the operating modes of the air conditioner may include heating mode, cooling mode, heating energy-saving mode, cooling energy-saving mode, dehumidification mode, health mode, blowing mode, etc. The user can select the desired operating mode through the mechanical buttons or touch buttons on the wired controller, or through a terminal device (such as a mobile phone, tablet computer, etc.), or through voice control. For example, when heating is required, the heating mode or the heating energy-saving mode can be selected; for example, when cooling is required, the cooling mode or the cooling energy-saving mode can be selected; for example, when dehumidification is required, the dehumidification mode can be selected.

[0040] When the user needs to use the heating energy-saving mode, a control instruction is sent through a wire controller or a terminal device. When the air conditioner receives the heating energy-saving mode instruction, it enters the heating energy-saving mode. In some embodiments, the heating energy-saving mode may include multiple operating stages, and the operating frequency of each operating stage is different to reduce the energy consumption of the air conditioner. The operating frequencies corresponding to the multiple operating stages can be determined by calling the pre-set operating frequency of the heating mode in each stage, or the frequency corresponding to each operating stage can be determined according to the outdoor ambient temperature. Then, the air conditioner is controlled according to the operating frequency corresponding to each operating stage, wherein the multiple operating stages are operated in sequence according to a pre-set order.

[0041] Exemplarily, when the air conditioner enters the heating energy-saving mode, the air conditioner is controlled to operate at a higher operating frequency first, so that the indoor ambient temperature quickly approaches the set temperature. After the indoor ambient temperature approaches the set temperature, or the time of operation at the higher operating frequency reaches the set time, the air conditioner is controlled to operate at a medium operating frequency to make the indoor ambient temperature closer to the set temperature. After the indoor ambient temperature reaches the set temperature, or the time of operation at the medium operating frequency reaches the set time, the air conditioner is controlled to operate at a lower operating frequency to make the indoor ambient temperature reach and maintain the set temperature, thereby reducing the energy consumption of the air conditioner and improving the user experience.

[0042] The control method of the air conditioner according to the embodiment of the present invention is described in detail below.

[0043] In some embodiments of the present invention, determining the operating frequencies corresponding to the multiple operating stages includes: determining the operating frequencies corresponding to the multiple operating stages according to the outdoor ambient temperature.

[0044] Specifically, since the outdoor ambient temperature directly affects the time it takes for the indoor ambient temperature to reach the set temperature, for example, when the outdoor ambient temperature is very low, when the air conditioner is not in heating energy-saving mode, the indoor ambient temperature is also very low. In order to allow the indoor ambient temperature to quickly approach the set temperature, the compressor needs to be controlled to operate at a very high operating frequency. However, if the outdoor ambient temperature is high, when the air conditioner is not in heating energy-saving mode, the indoor ambient temperature is also relatively high. Compared with the case where the indoor ambient temperature is very low, in the same time, the indoor ambient temperature can quickly approach the set temperature. When the indoor ambient temperature is high, the compressor operates at a lower frequency. Therefore, the operating frequency of each stage can be set according to the outdoor ambient temperature, as shown in Table 1. Taking the heating energy-saving mode including three operating stages as an example, the operating frequency (compressor operating frequency) of the first operating stage is represented by F1eco, the operating frequency of the second operating stage is represented by F2eco, and the operating frequency of the third operating stage is represented by F3eco. F1eco>F2eco>F3eco, T4 represents the outdoor ambient temperature, when 2℃<T4≤6℃, the operating frequency of the first operating stage is F1eco_2, the operating frequency of the second operating stage is F2eco_2, and the operating frequency of the third operating stage is F3eco_2. When 6℃<T4≤11℃, the operating frequency of the first operating stage is F1eco_6, the operating frequency of the second operating stage is F2eco_6, and the operating frequency of the third operating stage is F3eco_6. Among them, in Table 1, F1eco_2≥F1eco_6≥F1eco_11≥…≥F1eco_23, and similarly, F2eco_2≥F2eco_6≥F2eco_11≥…≥F2eco_23, F3eco_2≥F3eco_6≥F3eco_11≥…≥F3eco_23. In other words, the outdoor ambient temperature is negatively correlated with the operating frequency of each stage, that is, the higher the outdoor ambient temperature, the lower the corresponding operating frequency of each stage; the lower the outdoor ambient temperature, the higher the corresponding operating frequency of each stage.

[0045] Table 1

[0046]

[0047] It should be noted that the upper and lower limits of the outdoor ambient temperature range given in Table 1 are used as a specific example, and can also be more accurately determined to the operating frequencies of multiple operating stages corresponding to each specific outdoor ambient temperature. No limitation or detailed description is given here.

[0048] In some embodiments of the present invention, the multiple operation stages include a first operation stage, the operation frequency corresponding to the first operation stage is a first operation frequency, and the air conditioner is controlled according to the operation frequency corresponding to each operation stage, including: when receiving a heating energy-saving mode instruction, controlling the air conditioner to enter the first operation stage; and controlling the air conditioner according to the first operation frequency. The first operation frequency is a high operation frequency.

[0049] Furthermore, in some embodiments of the present invention, when the air conditioner is running in the heating energy-saving mode, the method further includes: obtaining the coil temperature of the indoor heat exchanger; and when the coil temperature of the indoor heat exchanger is greater than a first preset temperature, controlling the indoor fan to turn on. The first preset temperature can be calibrated according to actual conditions.

[0050] Specifically, when the air conditioner receives the heating energy-saving mode instruction, the air conditioner enters the heating energy-saving mode, and directly controls the air conditioner to enter the first operation stage. The operation frequency corresponding to the first operation stage is a high operation frequency (first operation frequency), and then the air conditioner is controlled according to the first operation frequency so that the indoor environment temperature can quickly approach the temperature set by the user (target setting temperature) to meet the needs of the user, thereby improving the user's comfort. Since the indoor fan blows cold air when it is just started, in order to prevent a bad experience for the user, in the initial stage of controlling the air conditioner to operate at the first operation frequency, the indoor fan is first controlled not to start. In the process of the air conditioner operating at the first operation frequency, the coil temperature of the indoor heat exchanger is detected in real time. When the coil temperature is greater than the first preset temperature, it means that the indoor fan is blowing hot air. At this time, the indoor fan is controlled to start to increase the indoor environment temperature, thereby reducing the energy consumption of the air conditioner, achieving the purpose of energy saving, and improving the user's comfort.

[0051] In some embodiments of the present invention, the multiple operation stages may further include a second operation stage, the operation frequency corresponding to the second operation stage is a second operation frequency, and the second operation frequency is less than the first operation frequency. In the process of controlling the air conditioner according to the first operation frequency, the above method further includes: when the temperature difference between the indoor ambient temperature and the target setting temperature is greater than the first preset difference, or the operation time of the first operation stage reaches the first preset time, controlling the air conditioner to enter the second operation stage; and controlling the air conditioner according to the second operation frequency. Among them, the target setting temperature, the first preset time and the first preset difference can be calibrated according to actual conditions, for example, the first preset difference is less than or equal to 0.

[0052] Specifically, when the air conditioner is operated in the heating energy-saving mode, the air conditioner is first controlled to enter the first operation stage, that is, the air conditioner is controlled at a high operation frequency so that the indoor ambient temperature can quickly approach the target setting temperature, and then the operation frequency of the air conditioner is controlled according to the relationship between the indoor ambient temperature and the target setting temperature. Among them, when the temperature difference between the indoor ambient temperature and the target setting temperature is greater than the first preset difference, it means that the current indoor ambient temperature is close to the target setting temperature. At this time, the air conditioner is controlled to operate at a relatively small operation frequency to reduce the energy consumption of the air conditioner. For example, the air conditioner is controlled to exit the first operation stage and enter the second operation stage, and the air conditioner is controlled to operate at the second operation frequency. Not only can it be determined whether to exit the first operation stage and enter the second operation stage according to the difference between the indoor ambient temperature and the target setting temperature, but it can also be determined whether to exit the first operation stage and enter the second operation stage according to the preset operation time of the first operation stage. For example, when the operation time of the first operation stage reaches the first preset time, the air conditioner is controlled to exit the first operation stage and enter the second operation stage. When the air conditioner enters the second operation stage, the operating frequency of the second operation stage is determined according to the outdoor ambient temperature, which is recorded as the second operating frequency. The air conditioner is controlled to operate at the second operating frequency to make the indoor ambient temperature closer to the target set temperature, meet user needs, and improve user experience. Since the operating frequency of the second stage is lower than the operating frequency of the first stage, the energy consumption of the air conditioner can be reduced, achieving the purpose of energy saving.

[0053] In some embodiments of the present invention, during the process of controlling the air conditioner according to the first operating frequency, the method further includes: when the temperature difference between the indoor ambient temperature and the target set temperature is less than or equal to the first preset difference, controlling the air conditioner to exit the heating energy-saving mode.

[0054] Specifically, in the process of controlling the air conditioner to operate at the first operating frequency, if the temperature difference between the indoor ambient temperature and the target set temperature is less than or equal to the first preset difference, it means that the indoor ambient temperature is low, and when operating in the energy-saving operation mode, it cannot approach the target set temperature and cannot meet the needs of the user. At this time, the air conditioner is controlled to exit the heating energy-saving mode and operate in the normal heating mode so that the indoor ambient temperature reaches the target set temperature to meet the needs of the user and improve the user's comfort. On the contrary, if the temperature difference between the indoor ambient temperature and the target set temperature is greater than the first preset difference, the air conditioner is controlled to still operate in the heating energy-saving mode.

[0055] In some embodiments of the present invention, the multiple operation stages also include a third operation stage, the operation frequency corresponding to the third operation stage is a third operation frequency, and the third operation frequency is less than the second operation frequency. In the process of controlling the air conditioner according to the second operation frequency, the above method further includes: when the temperature difference between the indoor ambient temperature and the target set temperature is greater than the second preset difference, or the operation time of the second operation stage reaches the second preset time, controlling the air conditioner to enter the third operation stage, wherein the second preset difference is greater than the first preset difference; and controlling the air conditioner according to the third operation frequency. The second preset time and the second preset difference can be calibrated according to actual conditions, for example, the second preset difference is less than or equal to 0.

[0056] Specifically, when the air conditioner is operated in the heating energy-saving mode, the air conditioner is first controlled to enter the first operation stage, that is, the air conditioner is controlled at a high operation frequency so that the indoor ambient temperature can quickly approach the target setting temperature. When the air conditioner exits the first operation stage and enters the second operation stage, the air conditioner is controlled to operate according to the second operation frequency corresponding to the operation frequency of the second operation stage, and then the operation frequency of the air conditioner is controlled according to the relationship between the indoor ambient temperature and the target setting temperature. Among them, when the temperature difference between the indoor ambient temperature and the target setting temperature is greater than the second preset difference, it means that the current indoor ambient temperature is closer to the target setting temperature than the first operation stage. At this time, the air conditioner is controlled to operate at a relatively small operation frequency to reduce the energy consumption of the air conditioner. For example, the air conditioner is controlled to exit the second operation stage and enter the third operation stage, and the controller is controlled to operate at the third operation frequency. Not only can it be determined whether to exit the second operation stage and enter the third operation stage according to the difference between the indoor ambient temperature and the target setting temperature, but it can also be determined whether to exit the second operation stage and enter the third operation stage according to the preset operation time of the second operation stage. For example, when the operation time of the second operation stage reaches the second preset time, the air conditioner is controlled to enter the third operation stage. When the air conditioner enters the third operation stage, the operation frequency of the third operation stage is determined according to the outdoor ambient temperature, which is recorded as the third operation frequency. The air conditioner is controlled to operate at the third operation frequency so that the indoor ambient temperature reaches and maintains the target set temperature, meets user needs, and improves user experience. Since the operation frequency of the third stage is lower than the operation frequency of the second stage, the energy consumption of the air conditioner can be reduced, achieving the purpose of energy saving.

[0057] In some embodiments of the present invention, during the process of controlling the air conditioner according to the second operating frequency, the above method also includes: when the temperature difference between the indoor ambient temperature and the target set temperature is less than or equal to the second preset difference, controlling the air conditioner to enter the first operating stage.

[0058] Specifically, in the process of controlling the air conditioner to operate at the second operating frequency, if after a period of time (which can be the second preset time or the set time, and has no size relationship with the second preset time, and can be greater than or less than), the temperature difference between the indoor ambient temperature and the target set temperature is less than or equal to the second preset difference, it means that the indoor ambient temperature cannot approach the target set temperature and needs to be operated at a higher operating frequency. At this time, the air conditioner is controlled to enter the first operating stage and is controlled according to the first operating frequency corresponding to the first operating stage to meet user needs and improve user comfort.

[0059] In some embodiments of the present invention, in the process of controlling the air conditioner according to the third operating frequency, the method further includes: when the time when the air conditioner enters the third operating stage reaches a third preset time, if the indoor ambient temperature is less than the target set temperature, controlling the third operating frequency to increase at a preset rate until the indoor ambient temperature is equal to the target set temperature, wherein the upper limit value of the third operating frequency is less than or equal to the second operating frequency. The third preset time can be calibrated according to actual conditions.

[0060] Specifically, during the operation of the air conditioner at the third operating frequency, the time for the air conditioner to enter the third operating stage is counted. When the time to enter the third operating stage reaches a certain time (third preset time), if the indoor ambient temperature cannot reach the target setting temperature, that is, the indoor ambient temperature is less than the target setting temperature, it means that when the air conditioner is operated at the third operating frequency, it cannot meet the needs of the user. At this time, the third operating frequency can be controlled to be gradually adjusted in an increasing manner until the indoor ambient temperature reaches the target setting temperature, wherein the upper limit value of the third operating frequency after adjustment is less than or equal to the second operating frequency. Alternatively, when the indoor ambient temperature cannot reach the target setting temperature, the air conditioner is directly controlled to exit the third operating stage and directly enter the second operating stage to meet the needs of the user and improve the user's comfort.

[0061] The method of the embodiment of the present invention can divide the heating energy-saving mode into three operating stages, the frequency of the first operating stage is greater than the frequency of the second operating stage, and the frequency of the second operating stage is greater than the frequency of the third operating stage, thereby reducing the energy consumption of the air conditioner and achieving the purpose of energy saving while meeting user needs.

[0062] In some embodiments of the present invention, after controlling the indoor fan to turn on, the method further includes: determining the target coil temperature based on the indoor ambient temperature; adjusting the wind speed of the indoor fan based on the coil temperature of the indoor heat exchanger and the target coil temperature so as to maintain the coil temperature of the indoor heat exchanger at the target coil temperature.

[0063] Furthermore, in some embodiments of the present invention, the rotation speed of the indoor fan is positively correlated with the coil temperature of the indoor heat exchanger.

[0064] Specifically, after the air conditioner enters the heating energy-saving mode, the air conditioner is controlled to enter the first operation stage and operate at the first operation frequency. When the coil temperature of the indoor heat exchanger is greater than the first preset temperature, the indoor fan is controlled to turn on. After the indoor fan is controlled to turn on, in order to improve the user's comfort, the fan gear of the indoor fan is also adjusted to make the coil temperature of the indoor heat exchanger and the air outlet temperature stable, and the wind blown out is comfortable. Among them, the relationship between the coil temperature of the indoor heat exchanger and the indoor ambient temperature is shown in Table 2. When the indoor ambient temperature also changes, the coil temperature of the indoor heat exchanger needs to be adjusted. After the indoor fan is controlled to run, the indoor ambient temperature is obtained in real time. Then, according to the size of the indoor ambient temperature, it is determined that the current coil temperature of the indoor heat exchanger needs to be reduced to the target coil temperature. Among them, when the coil temperature of the indoor heat exchanger is larger, the speed of the indoor fan is larger; when the coil temperature of the indoor heat exchanger is smaller, the speed of the indoor fan is smaller. By controlling the speed of the indoor fan, the coil temperature of the indoor heat exchanger is maintained at a stable output, and a stable comfortable temperature is output to maintain comfort. For example, when the indoor ambient temperature T1 is less than or equal to 10°C, the corresponding target coil temperature of the indoor heat exchanger is T2_1. When the indoor ambient temperature is 20°C<T1≤25°C, the corresponding target coil temperature of the indoor heat exchanger is T2_4, where T2_1<T2_2<T2_3<T2_4. By controlling the speed of the indoor fan, the coil temperature of the indoor heat exchanger is maintained at the target coil temperature. When the coil temperature of the indoor heat exchanger is too high, the coil temperature of the indoor heat exchanger needs to be reduced so that the human body feels a comfortable temperature and maintains comfort.

[0065] Table 2

[0066] T1≤10℃ T2_1 10℃＜T1≤15℃ T2_2 15℃＜T1≤20℃ T2_3 20℃＜T1≤25℃ T2_4

[0067] Therefore, by adjusting the speed of the indoor fan according to the coil temperature of the indoor heat exchanger, the air blown by the indoor fan and the coil temperature are relatively stable, the blown air is comfortable, and the user comfort is improved.

[0068] As a specific example, Figure 2 As shown, the control method of the air conditioner of the present invention may include the following steps:

[0081] S213, the air conditioner shuts down or exits operation after receiving the end signal from the user.

[0082] It should be noted that the specific numerical values ​​mentioned above are only used as examples to illustrate the implementation of the present invention in detail, and should not be understood as limiting the present invention. In other examples or implementations or embodiments, other numerical values ​​can be selected according to the present invention, and are not specifically limited here.
