[0025] As described in the background section, air conditioners often operate at high frequency initially for rapid cooling or heating, which can cause a sudden drop or rise in room temperature. This "sudden cooling or heating" phenomenon can easily cause discomfort. Furthermore, there is a delay in the initial start-up and shutdown time of the air conditioner's rapid cooling or heating, resulting in excess power consumption and wasted resources.

[0029] This embodiment provides a control method for an air conditioner that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0030] Figure 2 This is a flowchart of an air conditioner control method according to an embodiment of the present invention. Figure 2 As shown, the method includes the following steps:

[0031] Step S1, First control step: Control the air conditioner to turn on and run in the initial state, which is the state in which the air conditioner compressor 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.

[0032] Specifically, when the air conditioner is installed in a house, the volume and air leakage of the house need to be detected, and the air conditioner runs in a normal mode to detect when the house reaches the target temperature when the air conditioner runs at the maximum power.

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

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

[0035] Step S3, judgment step: judge whether the current indoor temperature and the target temperature are equal;

[0036] Specifically, the current indoor temperature acquired in S2 is compared with the target temperature to determine whether the temperature in the 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, and the operating frequency of the air conditioner will decrease from this moment to maintain the indoor temperature. The target temperature is a temperature set by the user, and in general, the target temperature in summer is 25°C and the target temperature in winter is 29°C.

[0037] Step S4, determination step: in the case where the current indoor temperature and the target temperature are equal, the preset temperature change rate is determined according to the first acquired current indoor temperature, the target temperature and the first target time, and the first target time is the time when the first acquired current indoor temperature 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 decrease, the preset temperature change rate of the house when the air conditioner runs at the highest operating frequency is calculated according to the time when the first acquired current indoor temperature reaches the target temperature (the first target time), the first acquired current indoor temperature and the target temperature. The preset temperature change rate represents the heat exchange rate of the house, which has a preset relationship with the volume and air leakage of the house. 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 air leakage of the house is serious, 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, second control step: determine the target operating frequency of the compressor according to the preset temperature change rate, and the target operating frequency is lower than the highest operating frequency. When the air conditioner runs again, the air conditioner is controlled to run according to the target operating frequency.

[0040] Specifically, the target working frequency determined according to the determined preset temperature change rate is the optimal frequency at which the air conditioner operates in the room, and the air conditioner operates at the target working frequency to ensure that the indoor temperature changes slowly, so that the user can quickly adapt, and in the case of a relatively long air conditioner operating time, the air conditioner maintains the target working frequency to make the indoor temperature reach the target temperature, and the power consumption of the air conditioner during operation is reduced compared with the operating mode of the air conditioner in the prior art.

[0041] Through the embodiment, the air conditioner is first controlled to operate in a normal working condition, that is, the air conditioner is first controlled to operate at the highest frequency to make the indoor temperature reach the target temperature set by the user at the fastest speed, and in the above process, the current indoor temperature is acquired every first preset time period, it is judged whether the current indoor temperature reaches the target temperature, and in the case that the current indoor temperature reaches the target temperature, the preset temperature change rate of the air conditioner operating in the room is determined, the preset temperature change rate and the target working frequency have a preset relationship, the target working frequency is determined according to the preset temperature change rate, and the air conditioner is controlled to operate at the target working frequency in the room subsequently, so that the indoor temperature changes slowly compared with the case that the air conditioner in the prior art operates at the highest working frequency, the user's body temperature changes too fast, and the user may have cold shivering and slight sweating. According to the preset temperature change rate, the target working frequency for the room is determined, so that the indoor temperature slowly decreases or increases, and the user is unaware that the indoor temperature reaches the target temperature, thereby improving the user's comfort.

[0042] In some optional embodiments, the control method further comprises a loop step: in the case that the current indoor temperature and the target temperature are not equal, the acquisition step and the judgment step are re-executed at least once until the current indoor temperature and the target temperature are equal.

[0043] Specifically, the air conditioner needs a certain time to operate to make the indoor temperature reach the target temperature, in order to detect the time point at which the indoor temperature is consistent with the target temperature at the first time, the above-mentioned first preset time period is relatively short, therefore, it is likely that the current indoor temperature acquired in the above-mentioned 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 re-executed, the new current indoor temperature is acquired after the next first preset time period, it is judged whether the new current indoor temperature reaches the target temperature, if the new indoor temperature does not reach the target temperature, the steps S2 and S3 are re-executed again, until the newly detected current indoor temperature reaches the target temperature, 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 according to a mapping condition met by a range of the preset temperature change rate, the target operating frequency of the air conditioner can be determined.

[0045] In step S51, it is judged whether the preset temperature change rate meets a first mapping condition, the first mapping condition being that the preset temperature change rate is greater than or equal to a first threshold value; in a case where it is judged that the preset temperature change rate meets the first mapping condition, the target operating frequency is controlled to be in a first range.

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

[0047] In step S52, in a case where it is judged that the preset temperature change rate does not meet the first mapping condition, it is judged whether the preset temperature change rate meets a second mapping condition, the second mapping condition being that the preset temperature change rate is less than the first threshold value and greater than or equal to a second threshold value; in a case where it is judged that the preset temperature change rate meets the second mapping condition, the target operating frequency is controlled to be in a 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 value and greater than or equal to the second threshold value, 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 second threshold value can be 0.8, and the threshold value can be reasonably adjusted according to actual conditions, and is not specifically limited.

[0049] In step S53, in a case where it is judged that the preset temperature change rate does not meet the second mapping condition, it is judged whether the preset temperature change rate meets a third mapping condition, the third mapping condition being that the preset temperature change rate is less than the second threshold value; in a case where it is judged that the preset temperature change rate meets the third mapping condition, the target operating frequency is controlled to be in a 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, when the preset temperature change rate is less than the second threshold value, it indicates that the heat exchange rate of the current house is slow, and a large operating frequency is needed when the house is cooled or heated, and the current target operating frequency is determined to be high. In a case where it is ensured that the user feels comfortable, the current indoor temperature can be quickly brought to the target temperature.

[0051] In some optional embodiments, the control method further comprises:

[0052] In step 51, in the case where 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 air 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, for example, in an environment with a small difference from the target temperature, or in the case of a small room volume. The low air speed reduces the air flow rate, thereby reducing the energy consumption of the fan, which is particularly effective for the room (small room or room that has reached the comfortable temperature) that meets the first mapping condition of the preset temperature change rate. The air conditioning system avoids unnecessary energy waste through precise control, and improves the overall energy utilization efficiency. When the low air speed is running, the noise generated by the outdoor fan is small, and the low air speed mode can also reduce the air conditioning operation noise in the night, work or study, and other scenes that require a quiet environment.

[0053] In step 52, in the case where 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 air speed of the outdoor fan of the air conditioner is controlled to be medium. In the case where the room temperature change is moderate, the medium air speed helps to uniformly distribute the indoor temperature, avoids local overcooling or overheating, and improves the overall comfort of the environment. While ensuring effective circulation of indoor air, the influence on user comfort can be reduced.

[0054] In step 53, in the case where it is determined that the preset temperature change rate meets the third mapping condition, the current target operating frequency is determined to be high, and the air 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, for example, in a hot or cold environment, or in the case of a large room volume. The high air speed can significantly increase the air flow rate, quickly promote the exchange of indoor and outdoor air, accelerate the cooling or heating process of the room, and shorten the time to reach the set temperature.

[0055] In some optional embodiments, the control method further comprises:

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

[0057] Specifically, in the cooling mode, the generated air is cold (low temperature), and if a fault occurs in the compressor or the power module at this time, the temperature generated due to the fault will also be lower than normal. Therefore, by reducing the first protection temperature value and the second protection temperature value, the compressor or the power module operating in the cooling mode can be specifically protected.

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

[0059] Specifically, the hot air is generated in the heating mode, if the compressor or the power module fails at this time, the temperature generated by the failure under the holding of the hot air will also be higher than the normal case, therefore, the first protection temperature value and the second protection temperature value are increased, which can be targeted to protect the compressor or the power module running in the heating mode.

[0060] In some optional embodiments, the control method further comprises:

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

[0062] Specifically, there will be a certain difference in temperature throughout the year, when the ambient temperature differs greatly from the last time when the target working frequency of the air conditioner is determined (greater than the third threshold value, which can be 10℃, 15℃ or 20℃), in order to make the air conditioner more comfortable to use, the target working frequency of the air conditioner can be re-determined.

[0063] In the case where the difference between the first ambient temperature and the second ambient temperature is greater than the third threshold value, an update instruction is sent, and in the case where the air conditioner needs to be re-detected, the update instruction is issued. If the user's demand for the air conditioner is not great in the case of needing to update, the air conditioner can also be selected not to be updated.

[0064] In some optional embodiments, the control method further comprises:

[0065] In the case where the update instruction is received, the air conditioner performs 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 last time when the air conditioner determines the preset temperature change rate, and the specific steps can be referred to the description above.

[0067] For example, Figure 3As shown, the air conditioner is started, the compressor runs at the highest operating frequency, and the indoor unit and outdoor unit of the air conditioner are adjusted to the highest operating frequency. The current indoor temperature of the house is obtained after a first preset time period (which can be 30 seconds), a first determination is made to determine whether the current indoor temperature reaches the target temperature, and in the case of no, the previous step is returned to re-execute the current indoor temperature of the house after the next first preset time period, and the current indoor temperature is re-determined to reach the target temperature, until the first determination is yes, and the determination is stopped; in the case of yes, the first determination result is determined, the preset temperature change rate K (the first obtained current indoor temperature-target temperature / the time of the first obtained current indoor temperature to reach the target temperature) is determined; determine whether K≥1.05 (first threshold value), in the case of K≥1.05, according to the mapping relationship, the target operating frequency suitable for the current house is determined to be low, and this is recorded, so that the next time the air conditioner is started, it is run according to the low gear. In the case of K<1.05, determine whether K≥0.8 (second threshold value) and <1.05, in the case of 0.8≤K<1.05, according to the mapping relationship, the target operating frequency suitable for the current house is determined to be medium, and this is recorded, so that the next time the air conditioner is started, it is run according to the medium gear. In the case of K<0.8, according to the mapping relationship, the target operating frequency suitable for the current house is determined to be high, and this is recorded, so that the next time the air conditioner is started, it is run according to the medium gear.

[0068] The above is the running process of the air conditioner as a whole. The air conditioner has two modes of refrigeration and heating, and the corresponding parameters will be different. Specifically, in the refrigeration mode, the target temperature is about 25°C, the low gear of the target operating frequency is 16Hz-45Hz, the medium gear is 46Hz-60Hz, and the high gear is 60Hz-75Hz. The compressor discharge protection temperature is about 90°C, and the protection temperature of the power module is about 76°C. In the heating mode, the target temperature is about 29°C, the low gear of the target operating frequency is 36Hz-65Hz, the medium gear is 66Hz-80Hz, and the high gear is 81Hz-102Hz. The compressor discharge protection temperature is about 106°C, and the protection temperature of the power module is about 88°C.

[0069] The embodiment of the present application also provides a control device of an air conditioner. It should be noted that the control device of the air conditioner of the embodiment of the present application can be used to execute the control method for the air conditioner provided by the embodiment of the present application.

As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware, or a combination of software and hardware is also possible and contemplated.

[0070] The control device for the air conditioner provided in the embodiments of the present invention will be described below.

[0071] Figure 4 This is a schematic diagram of the control device for an air conditioner according to an embodiment of the present invention. Figure 4 As shown, the device includes: a first control module 100, used to execute a first control step: controlling the air conditioner to turn on and operate in an initial state, wherein the air conditioner compressor operates at its highest operating frequency, the indoor fan operates at its maximum operating speed, and the outdoor fan operates at its maximum operating speed; an acquisition module 200, used to execute an acquisition step: acquiring the current indoor temperature of the space where the air conditioner is located during a first preset time period of air conditioner operation; a judgment module 300, used to execute a judgment step: determining whether the current indoor temperature and the target temperature are equal; a determination module 400, used to execute a determination step: determining a preset temperature change rate based on the first acquired current indoor temperature, the target temperature, and a first target time, wherein the first target time is the time it takes for the first acquired current indoor temperature to reach the target temperature; and a second control module 500, used to execute a second control step: determining the target operating frequency of the compressor based on the preset temperature change rate, wherein the target operating frequency is lower than the highest operating frequency, and controlling the air conditioner to operate according to the target operating frequency when the air conditioner starts running again.

[0072] In this embodiment, the first control module first controls the air conditioner to operate under normal conditions, that is, controls the air conditioner to run at the highest frequency to quickly reach the target temperature set by the user. During the above process, the acquisition module acquires the current indoor temperature every first preset time period, and the judgment module determines whether the current indoor temperature has reached the target temperature.
