[0033] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0034] In this embodiment, the air conditioner includes one, two, or more indoor units and an outdoor unit. When some indoor units or the entire unit is in cooling mode, the outdoor unit can operate in heating mode. In this case, under the same conditions, the higher the outdoor humidity, the greater the heat exchange. Therefore, when the humidity is high, the outdoor fan of the air conditioner can be controlled to operate at a reduced speed to save energy. Conversely, when some indoor units or the entire unit is in heating mode, the outdoor unit can operate in cooling mode. In this case, the higher the outdoor humidity, the easier it is for the outdoor unit to frost. Therefore, when the humidity is high, the outdoor fan of the air conditioner can be controlled to operate at a reduced speed to slow down the frost formation on the outdoor unit, further saving energy while improving air conditioning performance and achieving optimal energy efficiency.

[0035] Figure 1 This is a schematic flowchart illustrating a method for controlling an outdoor unit of an air conditioner, provided in an embodiment of this disclosure. Figure 1 As shown, the control process of the outdoor unit of the air conditioner includes:

[0036] Step 101: After confirming that the air conditioner meets the current operating conditions, obtain the current outdoor humidity.

[0037] After the air conditioner is powered on, it can operate in either cooling or heating mode. In some embodiments, when the air conditioner is in cooling mode, some indoor units or the entire unit may operate in cooling mode, while the outdoor unit may operate in heating mode; that is, one or more indoor units may operate in cooling mode, and the outdoor unit in heating mode. Conversely, when the air conditioner is in heating mode, some indoor units or the entire unit may operate in heating mode, while the outdoor unit may operate in cooling mode; that is, one or more indoor units may operate in heating mode, and the outdoor unit in cooling mode. In this case, it can be determined that the air conditioner meets the current operating conditions, and the outdoor humidity can be obtained.

[0038] It can monitor outdoor humidity, and obtain the monitored outdoor humidity at regular intervals or in real time, with the current outdoor humidity corresponding to the current moment.

[0039] Step 102: When the current outdoor temperature is greater than the set humidity value, determine the current wind speed reduction strategy that matches the current outdoor unit operating mode under the current operating conditions.

[0040] When an air conditioner is operating in cooling mode, the outdoor unit runs in heating mode. Under otherwise identical conditions, higher outdoor humidity results in greater heat exchange, necessitating a reduction in the outdoor fan speed to conserve resources. Conversely, when the air conditioner is operating in heating mode, the outdoor unit runs in cooling mode. Higher outdoor humidity makes the outdoor unit more prone to frost buildup, requiring a reduction in the outdoor fan speed to slow down frost formation, thus conserving resources and improving air conditioner efficiency. Therefore, regardless of whether the air conditioner is operating in cooling or heating mode, if the current outdoor temperature exceeds the set humidity value, it indicates high outdoor humidity, requiring a reduction in the outdoor fan speed. The set humidity value can be determined based on the air conditioner's performance, the geographical region, and the season of use. For example, in summer, the same model of air conditioner might have a set humidity of 55% in southern regions and 60% in northern regions. Generally, the set humidity value can be the upper limit of the comfortable humidity range for humans.

[0041] Furthermore, the reduction method of the outdoor fan varies depending on the outdoor unit's operating mode. Therefore, it's necessary to determine a current fan speed reduction strategy that matches the current outdoor unit's operating mode under the current operating conditions. In heating mode, the outdoor unit needs to reduce the outdoor fan speed to save resources; therefore, the fan speed can be reduced based on humidity, either in stages or in increments. In cooling mode, the outdoor unit needs to reduce the outdoor fan speed to slow down the frosting process; therefore, the fan speed can be reduced over time, i.e., the reduction is continuous and gradual. Thus, in some embodiments, determining the current fan speed reduction strategy that matches the current outdoor unit's operating mode under the current operating conditions includes: when the current outdoor unit is in heating mode, a first fan speed reduction strategy based on humidity is determined as the current fan speed reduction strategy; when the current outdoor unit is in cooling mode, a second fan speed reduction strategy based on time is determined as the current fan speed reduction strategy.

[0042] The first wind speed reduction strategy may include: monitoring outdoor humidity, and reducing the outdoor fan speed by a set percentage for every increase in outdoor humidity by a first set value. For example: reducing the outdoor fan speed by 5% for every 10% increase in outdoor humidity; or reducing the outdoor fan speed by 3% for every 5% increase in outdoor humidity; or reducing the outdoor fan speed by 1% for every 2% increase in outdoor humidity, and so on.

[0043] The second wind speed reduction strategy may include reducing the outdoor fan speed at a set rate. For example, reducing the outdoor fan speed by 0.6% every 3 minutes, or reducing the outdoor fan speed by 1% every 10 minutes, etc.

[0044] Step 103: Based on the current wind speed reduction strategy, control the outdoor fan of the air conditioner to operate at a reduced speed.

[0045] In some embodiments, when the current wind speed reduction strategy is the first wind speed reduction strategy, controlling the outdoor fan of the air conditioner to reduce its speed includes: obtaining the current humidity difference between the monitored outdoor humidity and the current outdoor humidity; reducing the current speed of the outdoor fan based on the current humidity difference and a first ratio between the reduction rate and the humidity difference to obtain the reduced speed; determining the reduced speed as the current speed, and controlling the outdoor fan to run at the current speed.

[0046] Of course, if the outdoor humidity continues to increase, the wind speed still needs to be reduced. This means the monitored outdoor temperature is taken as the current outdoor temperature, and the wind speed is reduced based on the humidity. Even after the monitored outdoor temperature is determined to be the current outdoor temperature, it is clearly still higher than the set humidity value. The outdoor temperature is then monitored again. The humidity difference between the monitored outdoor humidity and the current outdoor humidity is calculated using the first ratio between the reduction rate and the humidity difference to obtain the corresponding reduction rate. Therefore, multiplying the current wind speed by (1 - reduction rate) gives the reduced wind speed. The first ratio is the ratio between the reduction rate and the humidity difference, for example, the ratio between 5% and 10, 3% and 5, etc.

[0047] In some embodiments, when the current wind speed reduction strategy is the second wind speed reduction strategy, controlling the outdoor fan of the air conditioner to reduce its speed includes: obtaining the current rotational speed of the outdoor fan; reducing the current rotational speed according to a second ratio value between the reduction rate and the time elapsed, and controlling the outdoor fan to operate at the reduced speed. The second ratio value may be a ratio between 1% and 10 minutes, or a ratio between 0.5% and 5 minutes, etc.

[0048] As can be seen, in this embodiment of the present disclosure, when the air conditioner meets the current operating conditions, it determines a wind speed reduction strategy that matches the outdoor unit's operating mode based on the outdoor humidity, and controls the outdoor fan of the air conditioner to reduce its speed according to the wind speed reduction strategy. Specifically, when the outdoor unit is in heating mode, the wind speed is reduced based on humidity; while when the outdoor unit is in cooling mode, the wind speed is reduced based on time. Thus, different reduction strategies are adopted for different operating modes, which improves the performance of the air conditioner and achieves better energy efficiency while ensuring the reliability of the air conditioner's operation and meeting the user's comfort requirements.

[0049] The following describes the operation process in a specific embodiment, illustrating the control process for an outdoor air conditioning unit provided by the embodiments of the present invention.

[0050] In one embodiment of this disclosure, the air conditioner is operating in cooling mode, and the set humidity value can be 60%, while the first ratio value can be the ratio between 5% and 10% humidity values.

[0051] Figure 2 This is a schematic flowchart illustrating a method for controlling an outdoor unit of an air conditioner, provided in an embodiment of this disclosure. Figure 2As shown, the control process of the air conditioner outdoor unit includes:

[0052] Step 201: The air conditioner operates in cooling mode for one or more indoor units and heating mode for the outdoor unit.

[0053] Step 202: The air conditioner obtains the current outdoor humidity Rh.

[0054] Step 203: Determine if Rh > 60% is true. If yes, proceed to step 204; otherwise, end the process.

[0055] Step 204: The air conditioner will determine the current wind speed reduction strategy based on the first wind speed reduction strategy that reduces humidity.

[0056] Step 205: The air conditioner acquires the monitored outdoor humidity and obtains the current humidity difference between the monitored outdoor humidity and the current outdoor humidity.

[0057] Step 206: The air conditioner calculates the current reduction rate based on the current humidity difference and the first ratio value, and multiplies the current speed of the outdoor fan by (1 - current reduction rate) to obtain the reduced speed.

[0058] Step 207: The air conditioner determines the reduced speed as the current speed and controls the outdoor fan to run at the current speed.

[0059] Step 208: The air conditioner will monitor the outdoor temperature and determine it as the current outdoor temperature, then return to step 205.

[0060] As can be seen, in this embodiment, when some indoor units or the whole unit are running in cooling mode, the outdoor unit can be running in heating mode. At this time, the outdoor fan speed is reduced according to the humidity. The greater the increase in humidity, the greater the decrease in outdoor fan speed. While ensuring the reliability of air conditioner operation and meeting user comfort, energy is saved and the optimal energy efficiency of air conditioner is ensured.

[0061] In one embodiment of this disclosure, the air conditioner operates in heating mode at 55%, while the second ratio value may be a ratio between 1% and 10 minutes.

[0062] Figure 3 This is a schematic flowchart illustrating a method for controlling an outdoor unit of an air conditioner, provided in an embodiment of this disclosure. Figure 3 As shown, the control process of the air conditioner outdoor unit includes:

[0063] Step 301: The air conditioner operates in heating mode for one or more indoor units and cooling mode for the outdoor unit.

[0064] Step 302: The air conditioner obtains the current outdoor humidity Rh.

[0065] Step 303: Determine if Rh > 55% is true. If yes, proceed to step 304; otherwise, end the process.

[0066] Step 304: The air conditioner will determine the second wind speed reduction strategy based on time as the current wind speed reduction strategy.

[0067] Step 305: The air conditioner obtains the current time difference, and based on the current time difference and the second ratio value, it obtains the current reduction rate, and multiplies the current speed of the outdoor fan by (1 - current reduction rate) to obtain the reduced speed.

[0068] Step 306: The air conditioner determines the reduced speed as the current speed and controls the outdoor fan to run at the current speed. Return to step 305.

[0069] As can be seen, in this embodiment, when some indoor units or the whole unit are running in heating mode, the outdoor unit can be running in cooling mode. At this time, the outdoor fan speed is gradually reduced over time to slow down the frosting speed of the outdoor unit, thereby further saving energy and improving air conditioning performance, and achieving better energy efficiency.

[0070] Based on the above process for controlling an outdoor air conditioning unit, a device for controlling an outdoor air conditioning unit can be constructed.

[0071] Figure 4 This is a schematic diagram of a control device for an outdoor unit of an air conditioner provided in an embodiment of this disclosure. Figure 4 As shown, the air conditioner outdoor unit control device 400 includes: an acquisition module 410, a determination module 420, and a control module 430.

[0072] The acquisition module 410 is configured to acquire the current outdoor humidity when it is determined that the air conditioner meets the current operating conditions.

[0073] The module 420 is configured to determine a current wind speed reduction strategy that matches the current outdoor unit operating mode under the current operating conditions when the current outdoor temperature is greater than the set humidity value.

[0074] The control module 430 is configured to control the outdoor fan of the air conditioner to operate at a reduced speed according to the current wind speed reduction strategy.

[0075] In some embodiments, the system further includes: a determination module configured to determine that the air conditioner meets current operating conditions when one or more indoor units of the air conditioner are operating in cooling mode and the outdoor unit is operating in heating mode; and to determine that the air conditioner meets current operating conditions when one or more indoor units of the air conditioner are operating in heating mode and the outdoor unit is operating in cooling mode.

[0076] In some embodiments, the determining module 420 includes:

[0077] The first determining unit is configured to determine the first wind speed reduction strategy based on humidity reduction as the current wind speed reduction strategy when the current outdoor unit is in heating mode.

[0078] The second determining unit, when the current outdoor unit is in cooling mode, determines the second wind speed reduction strategy based on time to be the current wind speed reduction strategy.

[0079] In some embodiments, the control module 430 includes:

[0080] The first control unit is configured to acquire the current humidity difference between the monitored outdoor humidity and the current outdoor humidity, reduce the current speed of the outdoor fan based on the current humidity difference and a first ratio between the reduction rate and the humidity difference, obtain the reduced speed, determine the reduced speed as the current speed, and control the outdoor fan to run at the current speed.

[0081] In some embodiments, the first control unit is further configured to determine the monitored outdoor temperature as the current outdoor temperature and continue to reduce the wind speed based on humidity.

[0082] In some embodiments, the control module 430 includes:

[0083] The second control unit is configured to acquire the current speed of the outdoor fan; reduce the current speed according to a second ratio value of the reduction rate and time prior, and control the outdoor fan to operate at the reduced speed.

[0084] The control process of an air conditioner outdoor unit for an air conditioner outdoor unit control device is further described below with reference to embodiments.

[0085] In this embodiment, the first ratio value stored in the air conditioner can be the ratio between 3% and 5% humidity values, and the second ratio value can be the ratio between 2% and 10 minutes. The set humidity value can be 60%.

[0086] Figure 5 This is a schematic diagram of a control device for an outdoor unit of an air conditioner provided in an embodiment of this disclosure. Figure 5 As shown, the air conditioner outdoor unit control device 400 includes: an acquisition module 410, a determination module 420, a control module 430, and an operation determination module 440. The determination module 420 includes: a first determination unit 421 and a second determination unit 422. The control module 430 includes: a first control unit 431 and a second control unit 432.

[0087] In this embodiment, when one or more indoor units of the air conditioner are in cooling mode and the outdoor unit is in heating mode, the operation determination module 440 can determine that the air conditioner is in cooling mode and meets the current operating conditions. Alternatively, when one or more indoor units of the air conditioner are in heating mode and the outdoor unit is in cooling mode, the operation determination module 440 can determine that the air conditioner is in cooling mode and meets the current operating conditions. In this case, the current outdoor humidity Rh is obtained by the acquisition module 410.

[0088] Thus, if Rh > 60%, and the current outdoor unit is in heating mode, the first determining unit 421 in the determining module 420 can determine the first fan speed reduction strategy as the current fan speed reduction strategy. Then, the first control unit 431 in the control module 430 acquires the monitored outdoor humidity and obtains the current humidity difference between the monitored outdoor humidity and the current outdoor humidity. Based on the current humidity difference and the first proportional value, it obtains the current reduction rate, multiplies the current speed of the outdoor fan by (1 - the current reduction rate), obtains the reduced speed, determines the reduced speed as the current speed, and controls the outdoor fan to operate at the current speed. Furthermore, the first control unit 431 also determines the monitored outdoor temperature as the current outdoor temperature and continues to reduce the fan speed based on the humidity.

[0089] If Rh > 60%, and the current outdoor unit is in cooling mode, the second determining unit 422 in the determining module 420 can determine the second fan speed reduction strategy as the current fan speed reduction strategy. Then, the second control unit 432 in the control module 430 obtains the current time difference and, based on the current time difference and the second proportional value, calculates the current reduction rate. It then multiplies the current speed of the outdoor fan by (1 - the current reduction rate) to obtain the reduced speed, determines the reduced speed as the current speed, and controls the outdoor fan to operate at the current speed.

[0090] As can be seen, in this embodiment, when the air conditioner is cooling or heating, the device for controlling the outdoor unit of the air conditioner determines a wind speed reduction strategy that matches the outdoor unit's operating mode based on the outdoor humidity, and controls the outdoor fan of the air conditioner to reduce its speed according to the wind speed reduction strategy. In this way, the outdoor fan adopts different reduction strategies depending on the outdoor humidity, which improves the air conditioner's performance and achieves better energy efficiency while ensuring the reliability of the air conditioner's operation and meeting the user's comfort.
