Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a method and apparatus for controlling an air conditioner, an air conditioner, and a storage medium. Background Technology

[0002] Currently, to enhance the user experience, air conditioners often include internal programs such as anti-cold air features. However, this can lead to the coils not reaching a sufficient temperature when the air conditioner is first turned on, while a significant amount of heat has already accumulated in the air ducts. At this time, the indoor fan operates at a very low speed or even remains stationary, which can affect the lifespan of components such as the electric heater.

[0003] A control method for an air conditioner is disclosed in the related technology. The air conditioner is equipped with a positive temperature coefficient (PTC) electric heating device. The method includes: acquiring the real-time current change rate during the operation of the PTC electric heating device; comparing the real-time current change rate with a real-time current change rate threshold; and controlling the air guide mechanism of the air conditioner to operate at a normal air guide angle when a first condition is met; the first condition includes at least that the real-time current change rate is less than the real-time current change rate threshold; and controlling the air guide mechanism to operate at an increased air guide angle when a second condition is met; the second condition includes at least that the real-time current change rate is not less than the real-time current change rate threshold, and the increased air guide angle is greater than the normal air guide angle.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] While the above method can adjust the temperature inside the duct based on the rate of change of current, heat continues to accumulate inside the duct even when the rate of change of current is relatively stable. Therefore, the actual temperature inside the duct cannot be accurately obtained using the rate of change of current. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a method and apparatus for controlling an air conditioner, an air conditioner, and a storage medium to improve the accuracy of obtaining the actual temperature inside the air duct during the air conditioner's startup in heating mode.

[0008] In some embodiments, the above method includes: obtaining the operating status of the electric heater; performing a coil temperature correction operation when the electric heater is in the on state; and controlling the fan speed according to the corrected coil temperature value.

[0009] Optionally, a coil temperature correction operation is performed, including: obtaining an indoor ambient temperature value; determining a compensation temperature value based on the indoor ambient temperature value; and setting the sum of the compensation temperature value and the actual coil temperature value as the corrected coil temperature value.

[0010] Optionally, controlling the fan speed based on the corrected coil temperature value includes: determining the target outlet air temperature value based on the corrected coil temperature value; determining the target fan speed based on the target outlet air temperature value; and controlling the fan to operate at the target speed.

[0011] Optionally, the target speed of the fan is determined based on the target outlet air temperature value, including: obtaining the actual outlet air temperature value; and configuring the first set speed as the target speed if the target outlet air temperature value is greater than the actual outlet air temperature value.

[0012] Optionally, obtaining the actual air outlet temperature value includes: obtaining indoor user information; and determining the actual air outlet temperature value corresponding to the air conditioner's operating status based on the indoor user information.

[0013] Optionally, if the target outlet air temperature is less than the actual outlet air temperature, the method further includes: configuring the second set speed as the target speed; wherein the first set speed is greater than the second set speed.

[0014] Optionally, when the electric heater is in the off state, the method further includes: acquiring the actual coil temperature value; determining the target outlet air temperature value based on the actual coil temperature value; determining the target speed of the fan based on the target outlet air temperature value; and controlling the fan to operate at the target speed.

[0015] In some embodiments, the above-described apparatus includes a processor and a memory storing program instructions, the processor being configured to execute, when running the program instructions, the method for controlling an air conditioner as described above.

[0016] In some embodiments, the air conditioner includes: an air conditioner body; and, as described above, a device for controlling the air conditioner, which is installed on the air conditioner body.

[0017] In some embodiments, the storage medium stores program instructions that, when executed, perform the method for controlling the air conditioner as described above.

[0018] The method, apparatus, air conditioner, and storage medium for controlling an air conditioner provided in this disclosure can achieve the following technical effects:

[0019] By monitoring the operation of the electric heater, the air conditioner determines whether there is a possibility of excessive heat accumulation in the air duct due to functions such as anti-cold airflow. If the electric heater is on, it is assumed that excessive heat accumulation in the air duct may negatively impact the air conditioner's components. In this case, a coil temperature correction operation is performed to ensure that the corrected coil temperature value obtained by the air conditioner is closer to the actual temperature in the air duct, thus improving the accuracy of the air conditioner's measurement of the actual temperature in the air duct. Then, based on the corrected coil temperature value, the fan speed is controlled to allow the accumulated heat in the air duct to be dissipated earlier, preventing damage to the lifespan of some components. This effectively ensures the accuracy of the air conditioner's fan start-up timing when operating in heating mode.

[0037] Combination Figure 1As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, comprising:

[0038] S110, the air conditioner obtains the operating status of the electric heater.

[0039] In this embodiment, the high temperature generated when the electric heater of the air conditioner is turned on can significantly impact the components of the air conditioner. Therefore, by acquiring the operating status of the electric heater, it is determined whether the air conditioner will accumulate excessive heat in the air duct due to functions such as anti-cold air, thereby negatively affecting the components of the air conditioner. Furthermore, this aims to avoid affecting the heating performance of the air conditioner.

[0040] S120, with the electric heater on, the air conditioner performs a coil temperature correction operation.

[0041] In this embodiment, when the electric heater is on, it is recognized that there is a possibility that excessive heat accumulation in the air duct may negatively affect the components of the air conditioner. At this time, the air conditioner performs a coil temperature correction operation to prevent the fan from being affected by functions such as anti-cold air and to adjust the temperature in the air duct in a timely manner.

[0042] Optionally, the air conditioner performs a coil temperature correction operation, including: the air conditioner acquiring an indoor ambient temperature value; the air conditioner determining a compensation temperature value based on the indoor ambient temperature value; and the air conditioner setting the sum of the compensation temperature value and the actual coil temperature value as the corrected coil temperature value.

[0043] Thus, since the indoor ambient temperature affects the air conditioner's load when the electric heater is detected to be on, the coil temperature value sent to the air conditioner needs to be processed to improve the accuracy of the air conditioner's temperature determination within its own air duct. Specifically, if the indoor ambient temperature is greater than 22℃, the compensation temperature value is any value within the range of [4.5, 5.5]℃. Preferably, it can be 4.9℃, 5℃, or 5.2℃. If the indoor ambient temperature is greater than 12℃ and less than or equal to 22℃, the compensation temperature value is any value within the range of [2.7, 3.5]℃. Preferably, it can be 2.8℃, 3℃, or 3.2℃. If the indoor ambient temperature is less than or equal to 12℃, the compensation temperature value is any value within the range of [1.6, 2.4]℃. Preferably, it can be 1.8℃, 2℃, or 2.2℃. This ensures that the coil temperature value obtained by the air conditioner can more accurately represent the actual temperature value within the air duct.

[0044] S130, the air conditioner controls the fan speed based on the corrected coil temperature value.

[0045] In this embodiment, when the electric heater is on, the air conditioner obtains a corrected coil temperature value. Based on the corrected coil temperature value, the fan speed is controlled more accurately to avoid excessive heat accumulation in the air duct, which could negatively impact the air conditioner's components.

[0046] Optionally, the air conditioner controls the fan speed based on the corrected coil temperature value, including: the air conditioner determining a target outlet air temperature value based on the corrected coil temperature value; the air conditioner determining a target fan speed based on the target outlet air temperature value; and the air conditioner controlling the fan to operate at the target speed.

[0047] The target outlet air temperature value is used to characterize the minimum outlet air temperature required to avoid the temperature inside the air duct affecting the lifespan of components. The target speed is used to characterize the fan speed at which the outlet air temperature can reach the target outlet air temperature value.

[0048] In this way, the target speed that matches the current heat value in the duct can be determined based on the corrected coil temperature value, which more accurately represents the actual temperature inside the duct. Therefore, the fan is controlled to operate at the target speed, allowing the air conditioner to deliver hot air into the room in advance, without being limited by functions such as anti-cold air, thus preventing excessive heat buildup in the duct.

[0049] The method for controlling an air conditioner provided in this disclosure improves the accuracy of the air conditioner's temperature judgment within the air duct, thus preventing damage to some components due to excessively high temperatures within the air duct. By monitoring the operating status of the electric heater, the air conditioner determines whether there is a possibility of excessive heat accumulation in the air duct due to functions such as anti-cold air. When the electric heater is on, it is determined that excessive heat accumulation in the air duct may negatively impact the air conditioner's components. In this case, a coil temperature correction operation is performed to ensure that the corrected coil temperature value obtained by the air conditioner is closer to the actual temperature value within the air duct. Then, based on the corrected coil temperature value, the fan speed is controlled to allow the accumulated heat in the air duct to be expelled earlier, preventing damage to the lifespan of some components. This effectively ensures the accuracy of the fan start-up timing judgment when the air conditioner is operating in heating mode.

[0050] Optionally, the air conditioner determines the target fan speed based on the target outlet air temperature value, including: the air conditioner acquiring the actual outlet air temperature value. If the target outlet air temperature value is greater than the actual outlet air temperature value, the first set speed is configured as the target speed.

[0051] In this way, by comparing the minimum outlet air temperature (which avoids affecting the lifespan of components due to temperature within the duct) with the actual outlet air temperature of the air conditioner, it can be determined whether the current fan speed is sufficient to meet the heat dilution requirements within the duct. If the target outlet air temperature is higher than the actual outlet air temperature, it is determined that the current fan speed is insufficient to meet the heat dissipation requirements of the duct. In this case, the fan speed is adjusted to a first set speed that meets the heat dilution requirements within the duct, and this first set speed is higher than the current fan speed.

[0052] Combination Figure 2 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0053] S210, the air conditioner obtains indoor user information and the operating status of the electric heater.

[0054] S220: The air conditioner calls the user's parameter model based on the indoor user information.

[0055] S230, with the electric heater on, the air conditioner performs a coil temperature correction operation to obtain a corrected coil temperature value.

[0056] S240, the air conditioner determines the duration of its operation in the current operating state.

[0057] S250: The air conditioner determines the actual outlet air temperature value of the parameter model at the current time point based on the running time.

[0058] S260: The air conditioner controls the fan speed based on the relationship between the corrected coil temperature and the actual outlet air temperature.

[0059] The method for controlling an air conditioner provided in this disclosure can obtain a parameter model of the indoor user in the current operating state of the air conditioner by acquiring indoor user information. Based on the operating duration of the air conditioner in this state, the actual outlet air temperature value of the parameter model at the current time point is determined. Therefore, based on different user habits, the outlet air temperature value most suitable for the user's usage habits in the current operating state of the air conditioner can be determined. In this way, while ensuring the user experience, the actual outlet air temperature value of the air conditioner can be determined efficiently and accurately based on the model. Furthermore, by correcting the relationship between the coil temperature value and the actual outlet air temperature value, the fan speed is determined to control the fan operation.

[0060] Optionally, if the target outlet air temperature is lower than the actual outlet air temperature, the air conditioner will configure the second set speed as the target speed. The first set speed is greater than the second set speed.

[0061] This ensures efficient heat accumulation within the air duct, allowing the air conditioner to quickly meet the conditions for delivering hot air into the room, effectively reducing the air conditioner's energy consumption. Furthermore, the second set speed is lower than the current fan speed.

[0062] Optionally, with the electric heater off, the air conditioner acquires the actual coil temperature value. Based on the actual coil temperature value, the air conditioner determines the target outlet air temperature value. Based on the target outlet air temperature value, the air conditioner determines the target fan speed. The air conditioner controls the fan to operate at the target speed.

[0063] This allows the fan speed to be adjusted according to the actual operating conditions of the air conditioner. With the electric heater off, there is no significant heat buildup in the duct. At this time, the actual coil temperature reflects the actual temperature within the duct, and the target outlet air temperature is determined based on this value. Furthermore, the appropriate fan speed for the current operating mode is determined based on the target outlet air temperature.

[0064] Combination Figure 3 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0065] S300, the air conditioner obtains the actual coil temperature value.

[0066] S310, the air conditioner obtains the operating status of the electric heater.

[0067] S320, the air conditioner determines whether the electric heater is in operation. If yes, proceed to step S322; otherwise, proceed to step S321.

[0068] S321, the air conditioner determines the target air outlet temperature value based on the actual coil temperature value.

[0069] S322, the air conditioner determines the compensation temperature value based on the indoor ambient temperature.

[0070] S323, the air conditioner sets the sum of the compensated temperature value and the actual coil temperature value as the corrected coil temperature value.

[0071] S324, the air conditioner determines the target outlet air temperature value based on the corrected coil temperature value.

[0072] S330: The air conditioner determines the actual air outlet temperature value corresponding to the air conditioner's operating status based on the indoor user information.

[0073] S340, the air conditioner determines whether the target outlet air temperature is greater than the actual outlet air temperature. If yes, proceed to step S341; otherwise, proceed to step S342.

[0074] S341, the air conditioner sets the first set speed to the target speed.

[0075] S342, the air conditioner sets the second set speed to the target speed.

[0076] The method for controlling an air conditioner provided in this disclosure determines whether there is a risk of excessive heat accumulation in the air duct by acquiring the actual operating status of the electric heater. When the electric heater is running, the coil temperature value is corrected to more accurately represent the actual temperature inside the air duct, and then the target outlet air temperature value is determined based on the corrected coil temperature value. When the electric heater is off, the actual temperature inside the air duct is directly represented by the coil temperature, and then the target outlet air temperature value is determined based on the actual coil temperature value. Finally, a suitable target rotation speed is determined based on the target outlet air temperature value.

[0077] Specifically, taking an air conditioner operating in heating mode with a set temperature of 30℃ as an example: When the electric heater is off, the actual temperature detected by the coil is sent to the air conditioner without compensation. If the coil temperature is higher than the required temperature for cold air protection, the indoor fan motor rotates at 1200 RPM. If the coil temperature is lower than the required temperature for cold air protection, the indoor fan motor reduces its speed to 1000 RPM to ensure the outlet air temperature meets usage requirements. When the electric heater is on, the coil temperature is compensated based on the indoor ambient temperature before being sent to the air conditioner and compared with the temperature required for functions such as cold air protection. If the compensated coil temperature is higher than the required temperature for cold air protection, the indoor fan motor rotates at 1200 RPM. If the compensated coil temperature is lower than the required temperature for cold air protection, the indoor fan motor reduces its speed to 1000 RPM.
