[0028] In this embodiment of the disclosure, smart home appliances refer to home appliances formed by introducing microprocessors, sensor technology and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent sensing and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage smart home appliances.

[0029] In this embodiment of the disclosure, the terminal device refers to an electronic device with wireless connectivity.

[0030] When the outdoor ambient temperature is high, the air conditioner compressor's discharge pressure and load will be very high. If the torque output ratio is not adjusted, the output torque will be insufficient to drive the high load of the compressor, leading to compressor shutdown due to loss of synchronization. The method for controlling an air conditioner provided in this disclosure considers both the outdoor ambient temperature and the air conditioner's compressor discharge temperature when compensating for the compressor's torque. This allows the compressor to adjust the compensation torque according to temperature changes during operation. This results in more stable compressor operation and reduces the likelihood of compressor shutdown due to loss of synchronization.

[0031] Combination Figure 1 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, comprising:

[0032] Step S101: The air conditioner acquires the outdoor ambient temperature and the air conditioner compressor exhaust temperature.

[0033] Step S102: The air conditioner obtains the compressor frequency and the first torque output ratio corresponding to the compressor frequency.

[0034] In step S103, the air conditioner obtains the output compensation torque based on the first torque output ratio, the outdoor ambient temperature, and the air conditioner's compressor exhaust temperature.

[0035] In step S104, the air conditioner controls the operation of its compressor based on the output compensation torque.

[0036] The method for controlling an air conditioner provided in this disclosure can obtain an output compensation torque based on the torque output ratio, outdoor ambient temperature, and the air conditioner's compressor discharge temperature, and control the operation of the air conditioner's compressor based on the obtained output compensation torque. By considering both the outdoor ambient temperature and the air conditioner's compressor discharge temperature when calculating the compensation torque, the compressor can adjust the compensation torque according to temperature changes during operation. This allows the compressor to operate more stably, thereby reducing the possibility of compressor failure and shutdown.

[0037] Optionally, obtaining the first torque output ratio corresponding to the compressor frequency includes: performing a lookup operation in a preset data table based on the compressor frequency to obtain the first torque output ratio corresponding to the compressor frequency. The data table stores the correspondence between compressor frequency and torque output ratio.

[0038] In some instances, Table 1 is an example of a preset data table. As shown in Table 1, when the compressor frequency F is less than or equal to 35Hz, the torque output ratio is 98%; when the compressor frequency F is greater than 35Hz and less than or equal to 60Hz, the torque output ratio is 40%; and when the compressor frequency F is greater than 60Hz, the torque output ratio is 0%.

[0040] Table 1

[0041] Combination Figure 2 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0042] Step S201: The air conditioner acquires the outdoor ambient temperature and the air conditioner compressor exhaust temperature.

[0043] Step S202: The air conditioner obtains the compressor frequency.

[0044] In step S203, the air conditioner performs a lookup operation in a preset data table based on the compressor frequency to obtain the first torque output ratio corresponding to the compressor frequency. The data table stores the correspondence between the compressor frequency and the first torque output ratio.

[0045] In step S204, the air conditioner obtains the output compensation torque based on the first torque output ratio, the outdoor ambient temperature, and the air conditioner's compressor exhaust temperature.

[0046] In step S205, the air conditioner controls the operation of its compressor based on the output compensation torque.

[0047] The method for controlling an air conditioner provided in this disclosure compensates for the compressor's output torque by acquiring the compressor frequency, the torque output ratio corresponding to the compressor frequency, the outdoor ambient temperature, and the air conditioner's compressor discharge temperature. A lookup operation is performed in a preset data table based on the compressor frequency to obtain a first torque output ratio corresponding to the compressor frequency. Based on the first torque output ratio, the outdoor ambient temperature, and the air conditioner compressor's discharge temperature, an output compensation torque is obtained. This ensures that the air conditioner considers both the outdoor ambient temperature and the air conditioner's compressor discharge temperature when compensating for torque, allowing the compressor to adjust the compensation torque according to temperature changes during operation. This enables the compressor to operate more stably, reducing the likelihood of compressor shutdown due to malfunctions.

[0048] Optionally, the output compensation torque is obtained based on the first torque output ratio, the outdoor ambient temperature, and the compressor discharge temperature of the air conditioner, including:

[0049] When the outdoor ambient temperature is greater than the first preset value and / or the compressor exhaust temperature is greater than the second preset value, the second torque output ratio is calculated according to the first preset algorithm using the first torque output ratio, the outdoor ambient temperature and the air conditioner compressor exhaust temperature; the output compensation torque is calculated according to the second preset algorithm using the second torque output ratio and the preset initial torque.

[0050] Optionally, the first preset algorithm m = M + a × (T) is used. p -T1)+b×(T h -T2) Obtain the second torque output ratio. Where m is the second torque output ratio, and M is the first torque output ratio. a is the exhaust compensation coefficient, 0 ≤ a ≤ 2; for example, a can be set to 1. b is the outdoor ambient temperature compensation coefficient, 0 ≤ b ≤ 2; for example, b can be set to 1. T p T is the exhaust temperature of the air conditioner compressor. h The outdoor ambient temperature is used. T1 is the first preset value, and T2 is the second preset value. In some examples, the first preset value is 50℃, and an outdoor ambient temperature greater than 50℃ is considered high. The second preset value is 95℃, and an air conditioner compressor discharge temperature greater than 95℃ is considered high. At this time, the air conditioner compressor's discharge pressure and load will be very high, and the original output torque will be insufficient to drive the high load of the compressor, which will cause the compressor to stop out of step. By using the first torque output ratio, the outdoor ambient temperature, and the air conditioner compressor discharge temperature, the output compensation torque is obtained to compensate for the compressor torque. In this way, the compressor compensation torque takes into account the outdoor ambient temperature and the air conditioner compressor discharge temperature, so that the compressor can adjust the compensation torque according to temperature changes during operation. This allows the compressor to operate more stably and reduces the occurrence of compressor stoppage.

[0051] In some instances, at the compressor discharge temperature T of the air conditioner p >95℃ and / or outdoor ambient temperature T h At temperatures above 50℃, if the compressor frequency is greater than 35Hz and less than or equal to 60Hz, the first torque output ratio M matched in the database based on this compressor frequency is 40%. The second torque output ratio at this time is m = 40% + a × (T) p -95)+b×(T h -50).

[0052] In some embodiments, at the compressor discharge temperature T of the air conditioner p >95℃ and / or outdoor ambient temperature T h At temperatures above 50℃, if the compressor frequency is greater than 60Hz, the torque output ratio M matched to this compressor frequency in the database is 0%. In this case, the second torque output ratio m = 0% + a × (T) p -95)+b×(T h -50).

[0053] Optionally, the output compensation torque is calculated according to the second preset algorithm using the second torque output ratio and the preset initial torque, including:

[0054] Optionally, O = m × g can be calculated, where O is the output compensation torque, m is the second torque output ratio, and g is the preset initial torque.

[0055] When the outdoor ambient temperature is high, or the air conditioner compressor's discharge temperature is high, the compressor's discharge pressure and load will be very high. If the original output torque is insufficient to drive the high load, it will cause the compressor to stop out of step. A second torque output ratio is obtained by using the first torque output ratio, the outdoor ambient temperature, and the air conditioner's compressor discharge temperature. Then, an output compensation torque is obtained based on this second torque output ratio, thereby compensating for the compressor's torque when the outdoor ambient temperature or the air conditioner's compressor discharge temperature is high. This allows the compressor to operate more stably and reduces the likelihood of compressor stopping out of step.

[0056] Combination Figure 3 As shown, this disclosure provides another method for controlling an air conditioner, including:

[0057] Step S301: The air conditioner acquires the outdoor ambient temperature and the air conditioner compressor exhaust temperature.

[0058] Step S302: The air conditioner obtains the compressor frequency and the first torque output ratio corresponding to the compressor frequency.

[0059] In step S303, when the compressor exhaust temperature of the air conditioner is greater than the first preset value and / or the outdoor ambient temperature is greater than the second preset value, the air conditioner calculates the second torque output ratio according to the first preset algorithm using the first torque output ratio, the outdoor ambient temperature and the compressor exhaust temperature of the air conditioner.

[0060] In step S304, the air conditioner calculates the output compensation torque according to the second preset algorithm using the second torque output ratio and the preset initial torque.

[0061] In step S305, the air conditioner controls the compressor to operate based on the output compensation torque.

[0062] The method for controlling an air conditioner provided in this disclosure involves acquiring the compressor frequency, a first torque output ratio corresponding to the compressor frequency, the acquired outdoor ambient temperature, and the air conditioner's compressor discharge temperature. A second torque output ratio is then calculated based on the first torque output ratio, the outdoor ambient temperature, and the compressor discharge temperature. An output compensation torque is obtained based on the second torque output ratio, causing the output torque to increase as the acquired outdoor ambient temperature and the air conditioner's compressor discharge temperature increase. This allows for greater torque control of the compressor's operation when high outdoor ambient temperatures or high compressor discharge temperatures cause the compressor to stop out of sync, reducing the likelihood of compressor stoppage.

[0063] Optionally, the output compensation torque is obtained based on the first torque output ratio, the outdoor ambient temperature, and the compressor discharge temperature of the air conditioner, including: when the compressor discharge temperature of the air conditioner is less than or equal to a first preset value and the outdoor ambient temperature is less than or equal to a second preset value, the output compensation torque is obtained based on the first torque output ratio corresponding to the compressor frequency.

[0064] Optionally, O = M × g can be calculated, where O is the output compensation torque, M is the first torque output ratio, and g is the preset initial torque.

[0065] In some embodiments, when the outdoor ambient temperature is less than or equal to 50°C and the compressor exhaust temperature is less than or equal to 95°C, and the compressor frequency is greater than 35Hz and less than or equal to 60Hz, the first torque output ratio is 40%, then the output compensation torque O = 40% × g is obtained.

[0066] In some embodiments, when the outdoor ambient temperature is less than or equal to 50°C and the compressor exhaust temperature is less than or equal to 95°C, and the compressor frequency is greater than 60Hz, the first torque output ratio is 0%, then the output compensation torque O = 0% × g is obtained.

[0067] In some instances, when the outdoor ambient temperature is less than or equal to 50°C and the compressor exhaust temperature is less than or equal to 95°C, and the compressor frequency is less than or equal to 35Hz, the first torque output ratio is 98%, and the output compensation torque O = 98% × g is obtained.

[0068] Combination Figure 4 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0069] Step S401: The air conditioner acquires the outdoor ambient temperature and the air conditioner compressor exhaust temperature.

[0070] Step S402: The air conditioner obtains the compressor frequency and the first torque output ratio corresponding to the compressor frequency.

[0071] In step S403, when the compressor exhaust temperature of the air conditioner is less than or equal to a first preset value and the outdoor ambient temperature is less than or equal to a second preset value, the air conditioner obtains the output compensation torque according to the first torque output ratio corresponding to the compressor frequency.

[0072] In step S404, the air conditioner controls the compressor to operate based on the output compensation torque.

[0073] The method for controlling an air conditioner provided in this disclosure involves acquiring the compressor frequency, a first torque output ratio corresponding to the compressor frequency, the outdoor ambient temperature, and the air conditioner's compressor discharge temperature. When the air conditioner's compressor discharge temperature is less than or equal to a first preset value and the outdoor ambient temperature is less than or equal to a second preset value, an output compensation torque is obtained based on the first torque output ratio corresponding to the compressor frequency to control compressor operation. When the outdoor ambient temperature is less than or equal to 50°C and the compressor discharge temperature is less than or equal to 95°C, the air conditioner does not need to increase the compressor torque, thus achieving energy savings.

[0074] Combination Figure 5 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, the method comprising:

[0075] In step S501, the air conditioner obtains the outdoor ambient temperature and the air conditioner compressor discharge temperature, and then executes step S502.

[0076] Step S502: The air conditioner obtains the compressor frequency and the first torque output ratio corresponding to the compressor frequency.

[0077] Step S503: Determine whether the air conditioner compressor exhaust temperature is greater than the first preset value and / or whether the outdoor ambient temperature is greater than the second preset value. If the air conditioner compressor exhaust temperature is greater than the first preset value and / or the outdoor ambient temperature is greater than the second preset value, proceed to step S504. If the outdoor ambient temperature is less than or equal to the first preset value and the air conditioner compressor exhaust temperature is less than or equal to the second preset value, proceed to step S505.

[0078] Step S504: If the compressor frequency is greater than the third preset value, obtain the output compensation torque based on the first torque output ratio, the outdoor ambient temperature and the compressor exhaust temperature of the air conditioner.

[0079] Step S505: If the compressor frequency is less than or equal to the third preset value, obtain the output compensation torque according to the first torque output ratio corresponding to the compressor frequency.

[0080] In step S506, the air conditioner controls the compressor to operate based on the output compensation torque.

[0081] The method for controlling an air conditioner provided in this disclosure involves acquiring the compressor frequency, a first torque output ratio corresponding to the compressor frequency, the acquired outdoor ambient temperature, and the air conditioner's compressor discharge temperature. A second torque output ratio is calculated based on the first torque output ratio, the outdoor ambient temperature, and the air conditioner's compressor discharge temperature. An output compensation torque is then obtained based on the second torque output ratio. This ensures that the output torque increases with the acquisition of the outdoor ambient temperature and the air conditioner's compressor discharge temperature. Therefore, when the compressor stops operating due to high outdoor ambient temperature or high air conditioner compressor discharge temperature, a larger torque can be used to control the compressor's operation, thereby reducing the possibility of compressor out-of-sync shutdown.

[0083] The device for controlling an air conditioner provided in this embodiment acquires the outdoor ambient temperature and the air conditioner compressor discharge temperature through a first acquisition module; acquires the compressor frequency and a first torque output ratio corresponding to the compressor frequency through a second acquisition module; acquires an output compensation torque through a third acquisition module based on the first torque output ratio, the outdoor ambient temperature, and the air conditioner compressor discharge temperature; and controls the operation of the air conditioner compressor based on the output compensation torque, so that the output compensation torque increases as the acquired outdoor ambient temperature and the air conditioner compressor discharge temperature increase. Therefore, when the outdoor ambient temperature is high or the air conditioner compressor discharge temperature is high, causing the compressor to stop, the operation of the compressor can be controlled with a larger torque, reducing the occurrence of compressor out-of-sync shutdown.

[0084] Optionally, the second acquisition module is configured to perform a lookup operation in a preset data table based on the compressor frequency to obtain the first torque output ratio corresponding to the compressor frequency. The data table stores the correspondence between the compressor frequency and the first torque output ratio.

[0085] Optionally, the third acquisition module is configured to, when the compressor exhaust temperature of the air conditioner is greater than a first preset value and / or the outdoor ambient temperature is greater than a second preset value, calculate a second torque output ratio based on a first preset algorithm using a first torque output ratio, the outdoor ambient temperature, and the compressor exhaust temperature of the air conditioner. Then, it calculates an output compensation torque based on the second preset algorithm using the second torque output ratio and a preset initial torque.

[0086] Optionally, the third acquisition module is configured to acquire the output compensation torque based on the first torque output ratio corresponding to the compressor frequency when the exhaust temperature of the air conditioner is less than or equal to a first preset value and the outdoor ambient temperature is less than or equal to a second preset value.

Therefore, when the outdoor ambient temperature or the air conditioner's compressor exhaust temperature is high, causing the compressor to stop operating, the compressor operation can be controlled with a larger torque, reducing the possibility of the compressor stopping out of sync.
