[0002] The core function of an air conditioner is to perform heat exchange through a refrigerant circulation system to achieve cooling or heating of indoor air. However, during the long-term use of an air conditioner, its outdoor heat exchanger is prone to accumulating dust, or being blocked by foreign objects existing in the external environment, such as leaves, plastic bags, etc., resulting in a significant decline in the heat exchange performance of the outdoor heat exchanger.

[0003] However, in a high-temperature environment in summer, the outdoor heat exchanger of an air conditioner needs to efficiently release the heat absorbed indoors to the external environment. If the heat exchange of the outdoor heat exchanger is poor and the refrigerant cannot release heat in time, the pressure on the high-pressure side of the air conditioner system will rise significantly, which may cause the compressor to fail to start normally or frequently fail to start. Such failures not only affect the normal operation of the air conditioner but also impose additional loads on key components such as the compressor, accelerating equipment aging, shortening the service life, and increasing maintenance and replacement costs.

[0036] The present application will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] In some embodiments, refer to Figure 1 , Figure 1 which is a schematic flowchart of the first embodiment of the air conditioner control method of the present application. It should be noted that if there are substantially the same results, the method of the present application is not limited to Figure 1 the process sequence shown. As shown in Figure 1 , the air conditioner control method includes:

[0038] Step S101, when the air conditioner system detects that there is a poor heat exchange situation in the outdoor heat exchanger of the air conditioner system, control the compressor of the air conditioner system to start;

[0039] As an exemplary example, when the air conditioner system detects a poor heat exchange situation in the outdoor heat exchanger, the air conditioner system will consider that there is a current fault. Among them, poor heat exchange can mean that the external environmental temperature changes greatly, the surface of the outdoor heat exchanger is frosted or blocked, or the refrigerant flow is blocked, thereby causing the heat exchange efficiency of the outdoor heat exchanger to be low.

[0040] As an exemplary example, the air conditioner system can be built-in with at least one sensor, such as a temperature sensor, a pressure sensor, etc. The sensor can be used to detect the working state of the outdoor heat exchanger. The temperature sensor can be installed near the outdoor heat exchanger to detect the temperature change of the outdoor heat exchanger; the pressure sensor can be installed in the refrigerant pipeline to detect whether the refrigerant pressure of the system is within the normal range; in addition, a flow sensor can also be used to detect the refrigerant flow. By collecting sensor data through the air conditioner system and analyzing the sensor data, it is determined that the heat exchange of the outdoor heat exchanger is poor, and a signal is sent to start the compressor.

[0041] Step S102, in response to the startup failure instruction of the compressor, adjust the speed of the blower of the air conditioner system so that the compressor starts normally, thereby improving the heat exchange performance of the outdoor heat exchanger.

[0042] As an exemplary example, when the air conditioner system detects a poor heat exchange situation in the outdoor heat exchanger, the air conditioner system will consider that there is a current fault. Among them, poor heat exchange can mean that the surface of the outdoor heat exchanger is frosted or blocked by foreign objects, or the refrigerant flow of the outdoor heat exchanger is blocked, thereby causing the heat exchange efficiency of the outdoor heat exchanger to be low. Therefore, in this embodiment, it can be confirmed whether there is a poor heat exchange situation in the outdoor heat exchanger due to foreign object blockage or refrigerant flow blockage in the outdoor heat exchanger by detecting whether the compressor can start normally.

[0043] Among them, the compressor startup failure instruction indicates that foreign objects are accumulated in the outdoor unit air conditioner, the refrigerant flow rate is insufficient, or the system pressure is abnormal, resulting in the compressor being unable to operate normally.

[0044] As an exemplary example, the rotation speed of the fan can be adjusted according to the operating mode of the air conditioning system and the current rotation speed of the fan. For example, corresponding fan rotation speed adjustment strategies can be selected according to operating modes such as cooling, heating, or dehumidification to improve the temperature difference between the outdoor heat exchanger and the air, and then improve the air flow rate of the outdoor heat exchanger to remove foreign objects in the outdoor heat exchanger and enhance the heat exchange performance. In addition, after the fan rotation speed is adjusted, the air conditioning system attempts to start the compressor again. It can confirm whether the compressor can be started normally by current detection or receiving a feedback signal inside the compressor.

[0045] As another exemplary example, the air conditioning system can be controlled to enable the fan to perform a reverse blowing operation to change the air flow direction and control the rotation speed of the reverse blowing operation to remove foreign objects in the outdoor heat exchanger and enhance the heat exchange performance. In addition, after the fan rotation speed is adjusted, the air conditioning system attempts to start the compressor again. It can confirm whether the compressor can be started normally by current detection or receiving a feedback signal inside the compressor.

[0046] In this embodiment, by detecting that there is a situation of poor heat exchange in the outdoor heat exchanger, the compressor is started to confirm whether there are foreign objects in the outdoor heat exchanger. If the compressor cannot be started, the rotation speed of the fan is adjusted to maintain the cleanliness of the outdoor heat exchanger of the air conditioner outdoor unit, thereby enhancing the heat exchange efficiency of the outdoor heat exchanger.

[0047] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of the second embodiment of the air conditioning control method of this application. The method includes the following steps:

[0048] Step S201, the air conditioning system detects that there is a situation of poor heat exchange in the outdoor heat exchanger of the air conditioning system, and controls the compressor of the air conditioning system to start;

[0049] In some embodiments, step S201 may include: determining that there is a situation of poor heat exchange in the outdoor heat exchanger by detecting that the temperature of the outdoor heat exchanger is higher than a preset first threshold and / or the temperature of the compressor is higher than a preset second threshold through the air conditioning system.

[0050] As an exemplary example, the outdoor heat exchanger temperature being higher than the preset first threshold indicates that the operating temperature of the outdoor heat exchanger exceeds the normal expected range. At the same time, the compressor temperature being higher than the preset second threshold indicates an indirect manifestation of poor heat exchange in the outdoor heat exchanger.

[0051] Therefore, by detecting the temperature of the outdoor heat exchanger and the temperature of the compressor and comparing them with the preset thresholds, the system can determine whether there is a problem with heat exchange: If the temperature of the outdoor heat exchanger exceeds the first threshold, it indicates that there may be poor heat exchange in the outdoor heat exchanger. If the temperature of the compressor exceeds the second threshold, it indicates that the heat exchange of the system may not be carried out properly, resulting in the compressor consuming more energy during operation and the temperature rising. The combined effect of the two can determine that there is a problem with heat exchange in the air-conditioning system.

[0052] Among them, the implementation manner and beneficial effects of step S201 can be as described in step S101 above, and will not be elaborated here.

[0053] Step S202, in response to the compressor startup failure instruction, obtain the current external fan speed of the external fan of the air-conditioning system and the current internal fan speed of the internal fan.

[0054] As an exemplary example, if the compressor fails to start, the system can adjust the fan speed according to the operating mode of the air conditioner, which can change the speed and temperature distribution of the air flow. Therefore, in this embodiment, the heat exchange is optimized by changing the flow conditions of the indoor and outdoor air, improving the air flow volume of the outdoor heat exchanger, and thus enhancing the heat exchange efficiency of the outdoor heat exchanger.

[0055] Step S203, according to the operating mode of the air-conditioning system, adjust based on the current external fan speed and the current internal fan speed so that the compressor starts normally, thereby enhancing the heat exchange performance of the outdoor heat exchanger.

[0056] Among them, different operating modes have different requirements for the fan speed. To achieve the accuracy of dynamic control, dynamic adjustment can be performed based on the real-time monitoring of the current fan speed. This feedback mechanism enables the air-conditioning system to adjust the speeds of the external fan and the internal fan in a closed loop.

[0057] As an exemplary implementation manner, please refer to Figure 3 , when it is detected that the compressor fails to start due to poor heat exchange in the system, the operating mode of the air conditioner can be detected. When the cooling mode is detected, increase the external fan speed by x1 rpm and decrease the internal fan speed by y1 rpm. When the heating mode is detected, decrease the external fan speed by x2 rpm, and the internal fan speed changes from the stop fan state for preventing cold air to the y2 rpm speed state.

[0058] In some implementation manners, step S202 may include: detecting that the operating mode is the cooling mode or the dehumidifying mode, increasing a preset first value based on the current external fan speed, and decreasing a preset second value based on the current internal fan speed.

[0059] Among them, in the refrigeration mode or the dehumidification mode, the first value can be used as a control variable to determine how much the current speed of the outdoor fan needs to be additionally increased, rather than controlling the current speed of the outdoor fan to reach the first value. Similarly, the second value can be used as a control variable to determine how much the current speed of the indoor fan needs to be additionally decreased. By additionally increasing the speed of the outdoor fan, the air flow speed can be increased, and the heat dissipation capacity of the heat exchanger can be enhanced; at the same time, combined with additionally decreasing the speed of the indoor fan, the temperature difference between the outdoor heat exchanger and the air is improved as a whole.

[0060] The specific values of the first value and the second value can be determined according to the heat exchange area of the outdoor heat exchanger. The first value can be the same as or different from the second value. For example, the range of the first value can be 100 rpm to 500 rpm, and the range of the second value can be 100 rpm to 500 rpm.

[0061] The current speed of the outdoor fan and the current speed of the indoor fan can be collected through a speed sensor built in the air-conditioning system. When it is detected that the heat exchange is poor or the heat dissipation effect decreases, the air-conditioning system can forcibly increase the speed of the outdoor fan, and the increased speed is the first value; at the same time, forcibly decrease the speed of the indoor fan, and the decreased speed is the second value. Among them, the additional increase of the outdoor fan and the additional decrease of the indoor fan can be achieved by adjusting the drive voltage, frequency or pulse width modulation control method of the fan motor.

[0062] By increasing the speed of the outdoor fan in the refrigeration or dehumidification mode, the air flow speed can be increased, so that a stronger air flow can reduce the possibility of dust and dirt accumulating on the surface of the heat exchanger, and the increased speed makes the outdoor heat exchanger dissipate heat faster, the surface temperature is lower, reducing the water vapor condensation caused by the temperature difference, and avoiding the situation of dust adhering to the outdoor heat exchanger; the reduction of the speed of the indoor fan can reduce the heat exchange speed of the evaporator, thereby reducing the cold quantity of the refrigerant return flow and the load of the compressor. Thus, through the cooperation of increasing the speed of the outdoor fan and decreasing the speed of the indoor fan, the system pressure is made more stable, the flow rate of the outdoor heat exchanger is increased, the cleanliness of the outdoor heat exchanger of the air conditioner is maintained, and the heat exchange efficiency of the outdoor heat exchanger is improved.

[0063] As another exemplary example, step S202 may include: detecting that the operating mode is the heating mode, reducing a preset third value based on the current speed of the outdoor fan, and controlling the current speed of the indoor fan to increase a preset fourth value from a preset fan stop state.

[0064] Among them, in the heating mode, the third value can be used as a control variable to determine how much the outdoor fan needs to be additionally reduced rather than controlling the current speed of the outdoor fan to reach the third value. Similarly, the fourth value can be used as a control variable to determine how much the indoor fan needs to be additionally increased.

[0065] Among them, since the indoor fan is in a stopped state in the heating mode, the fourth value can be a low speed gear or a gentle breeze gear. Starting the indoor fan at a low speed can more smoothly guide the hot air into the room. Through the smooth transition from the stopped state to the gentle breeze gear, the air conditioning system can better control the temperature change, prevent cold air from directly blowing into the room, and improve the heating efficiency. At the same time, since the air conditioning system may not require too high a rotation speed to support heat exchange, especially in a low temperature environment, the energy consumption can be reduced.

[0066] As an exemplary example, the specific values of the third value and the fourth value can be determined according to the heat exchange area of the outdoor heat exchanger. The third value can be the same as or different from the fourth value. For example, the range of the third value can be 100 rpm to 500 rpm, and the range of the fourth value can be 100 rpm to 500 rpm.

[0067] By reducing the rotation speed of the outdoor fan in the heating mode, the heat dissipation speed of the outdoor heat exchanger can be slowed down, and the frosting phenomenon caused by too low temperature can be reduced; at the same time, since the condensed water on the surface of the heat exchanger is not easy to evaporate in the stopped state of the fan, it may be blown back into the indoor environment when the system resumes normal operation. Therefore, the indoor fan can be switched from the stopped state to the gentle breeze gear, so that the condensed water on the surface of the outdoor heat exchanger evaporates faster, avoiding pollutants carried by the condensed water from entering the indoor air. Reducing the circulation of moisture and maintaining the cleanliness of the outdoor heat exchanger of the air conditioner can further improve the heat exchange efficiency of the outdoor heat exchanger.

[0068] Please refer to Figure 4 , Figure 4 which is a schematic flowchart of the third embodiment of the air conditioner control method of the present application. The method includes the following steps:

[0069] Step S401, when the air conditioning system detects that there is a poor heat exchange situation in the outdoor heat exchanger of the air conditioning system, control the compressor of the air conditioning system to start;

[0070] Among them, the implementation manner and beneficial effects of step S401 can be as described in step S101 or step S201 above, and will not be elaborated here.

[0071] Step S402, in response to the startup failure instruction of the compressor, control the fan of the air conditioning system to perform a back-blowing operation, so that the compressor starts normally, and further improves the heat exchange performance of the outdoor heat exchanger; wherein, the back-blowing rotation speed of the back-blowing operation is a preset fifth value, and the back-blowing time of the back-blowing operation is a preset sixth value.

[0072] Among them, the back-blowing operation of the fan can be the back-blowing operation of the outdoor fan and / or the indoor fan. The back-blowing operation can remove the frost layer, dust or other substances that may hinder heat exchange on the outdoor heat exchanger.

[0073] Among them, the fifth value can determine the rotational speed that the blower needs to reach during the backflush operation. It should be noted that although a high rotational speed can clean the frost layer or dirt faster, an excessively high rotational speed may also damage the structure of the outdoor heat exchanger and may even affect the operation of the compressor. Therefore, the fifth value can be the minimum rotational speed for effective cleaning, so that when the blower performs the backflush operation, it can not only provide sufficient wind force, but also take into account the bearing capacity of the equipment and reduce the damage risk caused by too strong a wind flow.

[0074] In addition, different external environmental conditions, such as outdoor temperature, humidity, etc. may affect the frosting or dirtiness degree of the heat exchanger. Therefore, the fifth value can also be dynamically adjusted according to the current external environmental conditions. For example, if it is detected that the outdoor heat exchanger has a thick layer of frost, the fifth value will be set to a higher rotational speed to effectively remove the frost layer; if the frosting is light, the fifth value can be set to a lower rotational speed to reduce the burden on the blower.

[0075] Among them, the sixth value can determine the duration of the backflush operation. Although the backflush operation can help clean the heat exchanger, an overly long backflush operation may cause other problems. For example, if the blower runs at a high rotational speed for a long time, it will consume more power and increase the energy consumption of the air-conditioning system. Therefore, the sixth value is also used to balance the effect of the backflush operation and the long-term stable operation of the air-conditioning system.

[0076] Among them, the fifth value and the sixth value jointly determine the effect and efficiency of the backflush operation. By setting the fifth value and the sixth value to combine an appropriate rotational speed and a reasonable backflush time, the air-conditioning system can improve energy efficiency and long-term stability while cleaning the heat exchanger.

[0077] As an exemplary example, the specific values of the fifth value and the sixth value can be determined according to the heat transfer area of the outdoor heat exchanger. The fifth value can be the same as or different from the sixth value. For example, the range of the fifth value can be 600 rpm to 1200 rpm; the range of the sixth value can be 1 minute to 10 minutes.

[0078] Step S403, start the compressor, and in response to the start failure instruction of the compressor, return to execute the step of controlling the blower of the air-conditioning system to perform the backflush operation; repeat this until the backflush operation reaches a preset number of times, and then stop starting the compressor.

[0079] As an exemplary example, after the backflush operation is completed, the air-conditioning system can start the compressor again. If the compressor still fails to start, the air-conditioning system can continue to perform the backflush operation according to the control logic to repeat the above step S402, which can clean the outdoor heat exchanger and improve air circulation, increasing the possibility of the compressor starting.

[0080] Among them, the maximum number of purge operations can be set. If the purge operation is repeated up to the maximum number of times and the compressor still cannot be started, the purge operation of the fan and the start operation of the compressor are stopped, which can reduce equipment damage caused by excessive execution of the purge operation and avoid the system running in a fault state for a long time.

[0081] Among them, repeating the purge operation can increase the probability of successful startup of the compressor. If the purge operation still cannot start the compressor, the air conditioner system confirms that there is a more serious fault in the outdoor heat exchanger. Therefore, after step S403, it may include: sending an abnormal alarm to a mobile device communicating with the air conditioner system.

[0082] In an exemplary embodiment, please refer to Figure 5 , when it is detected that the startup of the compressor fails due to poor heat exchange in the system, the fan purge operation is started, the purge speed is y1 rpm, the purge time each time is x1 min, and after purging, the compressor is tried to be started again. If the compressor still fails to start, continue with the purge speed of y2 rpm and the purge time of x2 min, and continue to try to start the compressor. After starting in this way 2 times, if the compressor still fails to start, report the compressor startup failure fault code.

[0083] In this embodiment, through the purge operation of the fan, the air flow direction is changed in a short time, which can remove obstacles around the outdoor unit or in the heat exchanger fins, such as dust, moisture or small particles that may accumulate, and reduce the startup burden of the compressor; at the same time, the purge operation can change the air flow environment around the outdoor unit, thereby providing better startup conditions for the compressor.

[0084] Another technical solution adopted by this application is: to provide an air conditioner control device, the air conditioner control device includes: a detection module, which is used to detect that there is a situation of poor heat exchange in the outdoor heat exchanger of the air conditioner system and control the startup of the compressor of the air conditioner system; a control module, which is used to respond to the startup failure instruction of the compressor, adjust the speed of the fan of the air conditioner system, so that the compressor starts normally, and further improve the heat exchange performance of the outdoor heat exchanger.

[0085] Please refer to Figure 6 , Figure 6 is an exemplary structural block diagram of an electronic device for the air conditioner control method of this application. As Figure 6 shown, the electronic device 600 of this application may include a processor 601 and a memory 602, where the processor 601 and the memory 602 communicate through a bus. The memory 602 stores program instructions for air conditioner control. When the program instructions are executed by the processor 601, the above processor executes the above related method steps to implement an air conditioner control method in the above embodiment.

[0086] Please refer to Figure 7 , Figure 7 which is an exemplary structural block diagram of a computer-readable storage medium for the air conditioner control method of the present application. As Figure 7 shown, a computer program 701 is stored in the computer-readable storage medium 700. When the computer program 701 runs on a computer by a processor, the computer is caused to execute the above-related method steps to implement an air conditioner control method in the above embodiments.

[0087] In the above solution, when the air conditioner system detects that there is a problem with the heat exchange of the outdoor heat exchanger of the air conditioner system, the compressor of the air conditioner system is controlled to start; in response to the startup failure instruction of the compressor, the speed of the blower of the air conditioner system is adjusted so that the compressor starts normally, thereby improving the heat exchange performance of the outdoor heat exchanger. By detecting that there is a problem with the heat exchange of the outdoor heat exchanger, the compressor is started to confirm whether there is a foreign object in the outdoor heat exchanger. If the compressor cannot start, the speed of the blower is adjusted to keep the outdoor heat exchanger of the air conditioner clean, thereby improving the heat exchange efficiency of the outdoor heat exchanger.
