[0008] Optionally, the control method also includes: when the air conditioner is in cooling mode, controlling the first protection temperature value of the exhaust temperature of the compressor and the second protection temperature value of the power module of the air conditioner to be lowered; when the air conditioner is in heating mode, controlling the first protection temperature value and the second protection temperature value to be increased.

[0014] By applying the technical solution of the present invention, after the air conditioner is installed indoors, the air conditioner is first controlled to work in a normal working condition, that is, the air conditioner is controlled to run at the highest frequency first so that the indoor temperature reaches the target temperature set by the user at the fastest speed. In the above process, the current indoor temperature is obtained once after each first preset time period, and it is determined whether the current indoor temperature reaches the target temperature. When it is determined that the current indoor temperature reaches the target temperature, the preset temperature change rate of the air conditioner working in the room is determined. The preset temperature change rate has a preset relationship with the target working frequency. The target working frequency is determined according to the preset temperature change rate to control the air conditioner to run at the target working frequency in the room later, thereby making the indoor temperature slowly decrease or slowly increase compared to when the air conditioner in the prior art runs at the highest working frequency, so that the indoor temperature of the user reaches the target temperature without the user's knowledge, thereby improving the user's comfort. The present invention solves the problem that the rapid cooling or heating of the air conditioner during operation in the prior art causes extreme temperatures of sudden cold and hot in the room, thereby reducing the user experience.

[0029] In this embodiment, a method for controlling an air conditioner running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0030] Figure 2 FIG. 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0031] Step S1, a first control step: controlling the air conditioner to start and operate in an initial state, wherein the initial state is a state in which the compressor of the air conditioner operates at a highest operating frequency, the indoor fan operates at a maximum operating speed, and the outdoor fan operates at a maximum operating speed;

[0032] Specifically, when the air conditioner is installed in a house, it is necessary to detect the size and air leakage of the house. At this time, the air conditioner runs in a normal operation mode to detect when the house will reach the target temperature when the air conditioner runs at maximum power.

[0033] Step S2, an acquisition step: when the air conditioner is running for a first preset time period, the current indoor temperature of the space where the air conditioner is located is acquired;

[0034] Specifically, after the air conditioner has been running for a period of time (a first preset time period), the temperature in the house will change, and the current indoor temperature of the house is obtained for subsequent comparison with the target temperature.

[0035] Step S3, judging step: judging whether the current indoor temperature is equal to the target temperature;

[0036] Specifically, the current indoor temperature obtained in S2 is compared with the target temperature to determine whether the temperature in the current house reaches the target temperature. The moment when the indoor temperature reaches the target temperature is the last moment when the air conditioner runs at the highest operating frequency. From this moment on, the operating frequency of the air conditioner will be reduced to maintain the indoor temperature. The target temperature is the temperature set by the user. Generally, the target temperature in summer is 25°C and the target temperature in winter is 29°C.

[0037] Step S4, determination step: when it is determined that the current indoor temperature is equal to the target temperature, the preset temperature change rate is determined according to the current indoor temperature, the target temperature and the first target time obtained for the first time, and the first target time is the time when the current indoor temperature obtained for the first time reaches the target temperature.

[0038] Specifically, when the indoor temperature reaches the target temperature and the operating frequency of the air conditioner is about to start to decrease, the preset temperature change rate of the house to reach the target temperature when the air conditioner is running at the highest operating frequency is calculated based on the time when the current indoor temperature reaches the target temperature for the first time (the first target time), the current indoor temperature obtained for the first time, and the target temperature. The preset temperature change rate represents the heat exchange rate of the house, and has a preset relationship with factors such as the size of the house and the air leakage. For example, if the house is large, the first target time will be longer, and the preset temperature change rate will be smaller; if the house has serious air leakage, the first target time will be longer, and the preset temperature change rate will be smaller; if the house is large and the air leakage is serious, the first target time will be longer, and the preset temperature change rate will be smaller.

[0039] Step S5, the second control step: determine the target operating frequency of the compressor according to the preset temperature change rate, the target operating frequency is lower than the highest operating frequency, and when the air conditioner is running again, control the operation of the air conditioner according to the target operating frequency.

[0040] Specifically, the target operating frequency determined according to the preset temperature change rate determined above is the optimal frequency for the air conditioner to operate in the house. The air conditioner operates at the target operating frequency to ensure that the indoor temperature changes slowly so that the user can adapt quickly. When the air conditioner runs for a long time, the air conditioner maintains the target operating frequency so that the indoor temperature reaches the target temperature. In the above process, the electric energy consumed by the air conditioner operation will be reduced compared to the operation mode of the air conditioner in the prior art.

[0041] Through this embodiment, by first controlling the air conditioner to work in a normal working condition, that is, controlling the air conditioner to run at the highest frequency first so that the indoor temperature reaches the target temperature set by the user at the fastest speed, in the above process, the current indoor temperature is obtained once after each first preset time period, and it is determined whether the current indoor temperature reaches the target temperature. When it is determined that the current indoor temperature reaches the target temperature, the preset temperature change rate of the air conditioner working in the room is determined, and the preset temperature change rate has a preset relationship with the target working frequency. The target working frequency is determined according to the preset temperature change rate to control the air conditioner to run at the target working frequency in the room later, so that the indoor temperature is compared with the air conditioner in the prior art when it runs at the highest working frequency. The indoor temperature quickly becomes cold or hot, which easily causes the user's body temperature to change too quickly, thereby causing the user to shiver and sweat slightly. This application determines the target working frequency used for the house according to the preset temperature change rate, so that the indoor temperature slowly decreases or slowly increases, and the indoor temperature of the user reaches the target temperature without the user knowing it, thereby improving the user's comfort.

[0042] In some optional embodiments, the control method further includes: a loop step: when it is determined that the current indoor temperature and the target temperature are not equal, re-execute the acquisition step and the judgment step at least once until it is determined that the current indoor temperature and the target temperature are equal.

[0043] Specifically, it takes a certain amount of time for the air conditioner to reach the target temperature. In order to detect the time point when the indoor temperature is consistent with the target temperature in the first time, the first preset time period will be relatively short. Therefore, it is very likely that the current indoor temperature obtained in the above step S2 is lower than the target temperature (in the case of heating) or higher than the target temperature (in the case of cooling). At this time, the loop step is entered, and the steps S2 and S3 are returned to be executed again. The new current indoor temperature is obtained again after the next first preset time period, and it is determined whether the new current indoor temperature reaches the target temperature. If the new indoor temperature has not reached the target temperature, the steps S2 and S3 are returned to be executed again until the newly detected current indoor temperature reaches the target temperature, and the loop step is stopped and the step S4 is entered.

[0044] In some optional embodiments, there is a preset state table between the preset temperature change rate in step S5 and the target operating frequency of the compressor, and the target operating frequency of the air conditioner can be determined according to the mapping conditions satisfied by the range of the preset temperature change rate.

[0045] Step S51, determining whether the preset temperature change rate satisfies a first mapping condition, the first mapping condition being that the preset temperature change rate is greater than or equal to a first threshold; when determining that the preset temperature change rate satisfies the first mapping condition, controlling the target operating frequency to be within a first range.

[0046] For example, when the preset temperature change rate is greater than or equal to the first threshold, it indicates that the heat exchange rate of the current house is fast, and a large operating frequency is not required when cooling or heating the house, and the current target operating frequency is determined to be low. The above first threshold can be 1.05, which can be reasonably adjusted according to actual conditions and is not specifically limited.

[0047] Step S52, when it is determined that the preset temperature change rate does not meet the first mapping condition, determine whether the preset temperature change rate meets the second mapping condition, and the second mapping condition is that the preset temperature change rate is less than the first threshold and greater than or equal to the second threshold; when it is determined that the preset temperature change rate meets the second mapping condition, control the target operating frequency to be within the second range, and the minimum value of the second range is greater than or equal to the maximum value of the first range.

[0048] For example, when the preset temperature change rate is less than the first threshold and greater than or equal to the second threshold, it indicates that the heat exchange rate of the current house is medium, and the current target operating frequency is determined to be medium. The above second threshold can be 0.8, which can be reasonably adjusted according to actual conditions without specific limitation.

[0049] Step S53, when it is determined that the preset temperature change rate does not satisfy the second mapping condition, determine whether the preset temperature change rate satisfies the third mapping condition, and the third mapping condition is that the preset temperature change rate is less than the second threshold value; when it is determined that the preset temperature change rate satisfies the third mapping condition, control the target operating frequency to be within the third range, and the minimum value of the third range is greater than or equal to the maximum value of the second range.

[0050] For example, if the preset temperature change rate is less than the second threshold, it indicates that the heat exchange rate of the current house is slow, and a higher operating frequency is required for cooling or heating the house, and the current target operating frequency is determined to be high. The current indoor temperature will not reach the target temperature too slowly while ensuring the user's comfort.

[0051] In some optional implementations, the control method further includes:

[0052] In step 51, when it is determined that the preset temperature change rate meets the first mapping condition, the current target operating frequency is determined to be low, and the wind speed of the outdoor fan of the air conditioner is controlled to be low. In this case, the temperature change of the room can be completed in a short time, such as in an environment with a temperature not much different from the target temperature, or when the room volume is small. The low wind speed reduces the air flow rate, thereby reducing the energy consumption of the fan, which is particularly effective for houses (small rooms or rooms that have reached a comfortable temperature) that meet the preset temperature change rate of the first mapping condition. The air-conditioning system avoids unnecessary energy waste and improves the overall energy utilization efficiency through precise control. When running at a low wind speed, the noise generated by the outdoor fan is small. In scenes that require a quiet environment such as at night, work or study, the low wind speed mode can also reduce the noise of the air conditioner operation.

[0053] In step 52, when it is determined that the preset temperature change rate meets the second mapping condition, the current target operating frequency is determined to be medium, and the wind speed of the air conditioner's outdoor fan is controlled to be medium; when the room temperature changes moderately, the medium wind speed helps to evenly distribute the indoor temperature, avoid local overcooling or overheating, and improve the overall environmental comfort. While ensuring the effective circulation of indoor air, the impact on user comfort can be reduced.

[0054] In step 53, when it is determined that the preset temperature change rate satisfies the third mapping condition, the current target operating frequency is determined to be high, and the wind speed of the outdoor fan of the air conditioner is controlled to be high. In this case, the temperature change of the room needs to be accelerated, such as in a hotter or colder environment, or when the room volume is large. The high wind speed can significantly increase the air flow rate, quickly promote the indoor and outdoor air exchange, accelerate the cooling or heating process of the room, and shorten the time to reach the set temperature.

[0055] In some optional implementations, the control method further includes:

[0056] When the air conditioner is in cooling mode, a first protection temperature value for controlling the exhaust temperature of the compressor and a second protection temperature value of the power module of the air conditioner are reduced;

[0057] Specifically, in the cooling mode, cold air (low temperature) is generated. If the compressor or power module fails at this time, the temperature generated by the failure will also be lower than normal. Therefore, lowering the first protection temperature value and the second protection temperature value can specifically protect the compressor or power module operating in the cooling mode.

[0058] When the air conditioner is in the heating mode, the first protection temperature value and the second protection temperature value are controlled to increase.

[0059] Specifically, hot air is generated in the heating mode. If the compressor or power module fails at this time, the temperature caused by the failure will be higher than normal due to the hot air. Therefore, increasing the first protection temperature value and the second protection temperature value can specifically protect the compressor or power module operating in the heating mode.

[0060] In some optional implementations, the control method further includes:

[0061] After the second preset time period, obtaining the first ambient temperature; determining whether the difference between the first ambient temperature and the second ambient temperature when the preset temperature change rate was last determined is greater than a third threshold;

[0062] Specifically, there will be a certain temperature gap between the four seasons. When the ambient temperature is significantly different from the last time the target operating frequency of the air conditioner was determined (greater than the third threshold, which may be 10°C, 15°C or 20°C), the target operating frequency of the air conditioner may be re-determined to make the air conditioner more comfortable to use.

[0063] When it is determined that the difference between the first ambient temperature and the second ambient temperature is greater than the third threshold, an update instruction is sent, and when the air conditioner needs to be re-tested, an update instruction is sent. If the user does not have much demand for the air conditioner when an update is needed, the user may choose not to update.

[0064] In some optional implementations, the control method further includes:

[0065] When the update instruction is received, the air conditioner is controlled to execute the first control step, the acquisition step, the judgment step, the determination step and the second control step again to update the preset temperature change rate.

[0066] Specifically, the above updating process is the same as the process of the air conditioner last measuring the preset temperature change rate, and the specific steps can refer to the above description.

[0067] For example, Figure 3As shown, the air conditioner is controlled to start, the compressor runs at the highest working frequency, and the indoor unit and outdoor unit of the air conditioner are adjusted to the highest working frequency in coordination with the air conditioner. The current indoor temperature of the house is obtained after the first preset time period (which can be 30s), and a first judgment is made to determine whether the current indoor temperature has reached the target temperature. If the first judgment is no, return to the previous step to re-execute the current indoor temperature of the house after the next first preset time period, and re-judge whether the current indoor temperature has reached the target temperature, until the first judgment structure is yes and stop; if the first judgment result is yes, determine the preset temperature change rate K (|the current indoor temperature obtained for the first time-the target temperature| / the time when the current indoor temperature reaches the target temperature for the first time); determine whether K is ≥1.05 (the first threshold value), and if K is ≥1.05, determine the target working frequency applicable to the current house as a low gear according to the mapping relationship, and record it so that the air conditioner can be operated at a low gear the next time it is started. In the case of K < 1.05, it is determined whether K ≥ 0.8 (the second threshold) and < 1.05. In the case of 0.8 ≤ K < 1.05, the target operating frequency applicable to the current house is determined to be medium-range according to the mapping relationship, and this is recorded so that the air conditioner can be operated at medium-range the next time it is started. In the case of K < 0.8, the target operating frequency applicable to the current house is determined to be high-range according to the mapping relationship, and this is recorded so that the air conditioner can be operated at medium-range the next time it is started.

[0068] The above is the overall operation process of the air conditioner. The air conditioner has two modes: cooling and heating. The corresponding parameters of different modes will be different. Specifically, in the cooling mode, the target temperature is about 25°C, the low range of the target operating frequency is 16Hz~45Hz, the middle range is 46Hz~60Hz, and the high range is 60Hz~75Hz. The compressor exhaust protection temperature is about 90°C, and the power module protection temperature is about 76°C. In the heating mode, the target temperature is about 29°C, the low range of the target operating frequency is 36Hz~65Hz, the middle range is 66Hz~80Hz, and the high range is 81Hz~102Hz. The compressor exhaust protection temperature is about 106°C, and the power module protection temperature is about 88°C.

[0069] The embodiment of the present invention further provides a control device for an air conditioner.

Figure 4 As shown, the device includes: a first control module 100, which is used to execute a first control step: control the air conditioner to turn on and run in an initial state, where the initial state is a state in which the compressor of the air conditioner runs at the highest operating frequency, the indoor fan runs at the maximum operating speed, and the outdoor fan runs at the maximum operating speed; an acquisition module 200, which is used to execute an acquisition step: when the air conditioner runs for a first preset time period, the current indoor temperature of the space where the air conditioner is located is acquired; a judgment module 300, which is used to execute a judgment step: determine whether the current indoor temperature is equal to the target temperature; a determination module 400, which is used to execute a determination step: when it is determined that the current indoor temperature is equal to the target temperature, determine a preset temperature change rate according to the current indoor temperature, the target temperature and the first target time obtained for the first time, the first target time being the time when the current indoor temperature obtained for the first time reaches the same as the target temperature; a second control module 500, which is used to execute a second control step: according to the preset temperature change rate, determine the target operating frequency of the compressor, the target operating frequency is lower than the highest operating frequency, and when the air conditioner runs again, control the air conditioner to run according to the target operating frequency.

[0072] Through this embodiment, the first control module first controls the air conditioner to work in a normal working condition, that is, the air conditioner is controlled to run at the highest frequency first so that the indoor temperature reaches the target temperature set by the user at the fastest speed. In the above process, the acquisition module acquires the current indoor temperature once after the first preset time period, and the judgment module judges whether the current indoor temperature reaches the target temperature. In the case of judging that the current indoor temperature reaches the target temperature, the determination module determines the preset temperature change rate of the air conditioner working in the room, and the preset temperature change rate has a preset relationship with the target working frequency. The second control module determines the target working frequency according to the preset temperature change rate to control the air conditioner to run at the target working frequency in the room later, so that the indoor temperature is compared with the air conditioner in the prior art when it runs at the highest working frequency. The indoor temperature quickly becomes cold or hot, which easily makes the user's body temperature change too fast, thereby causing the user to shiver and sweat slightly. The present application determines the target working frequency used for the house according to the preset temperature change rate, so that the indoor temperature slowly decreases or slowly increases, and the indoor temperature of the user reaches the target temperature without knowing it, thereby improving the user's comfort.
