[0029] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0030] The terms "first", "second", etc. in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0031] Unless otherwise stated, the term "plurality" means two or more.

[0032] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0033] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0034] In the disclosed embodiment, the air conditioner includes one, two or more indoor units and an outdoor unit. When some of the indoor units or the whole machine are in cooling mode, the outdoor unit can be in heating mode. At this time, under other equal conditions, the higher the outdoor humidity, the greater the heat exchange amount. Therefore, when the humidity is high, the outdoor fan of the air conditioner can be controlled to slow down and run, which can save energy. When some of the indoor units or the whole machine are in heating mode, the outdoor unit can be in cooling mode. At this time, 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 slow down and run, slowing down the frost speed of the outdoor unit, further saving energy while improving the air conditioner performance and achieving better energy efficiency.

[0035] Figure 1 FIG. 1 is a flow chart of a method for controlling an outdoor unit of an air conditioner provided by an embodiment of the present disclosure. Figure 1 As shown in the figure, the process of controlling the outdoor unit of the air conditioner includes:

[0036] Step 101: When it is determined that the air conditioner meets the current operating conditions, the current outdoor humidity is obtained.

[0037] After the air conditioner is powered on, it can be operated in cooling mode or heating mode. In some embodiments, when the air conditioner is in cooling mode, some indoor units or the entire machine are in cooling mode, and the outdoor unit can be in heating mode, that is, one or more indoor units of the air conditioner are in cooling mode, and the outdoor unit is in heating mode. When the air conditioner is in heating mode, some indoor units or the entire machine are in heating mode, and the outdoor unit can be in cooling mode, that is, one or more indoor units of the air conditioner are in heating mode, and the outdoor unit is in cooling mode. At this time, it can be determined that the air conditioner meets the current operating conditions and the outdoor humidity can be obtained.

[0038] It can monitor the outdoor humidity and obtain the monitored outdoor humidity at regular intervals or in real time. The current time corresponds to the current outdoor humidity.

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

[0040] When the air conditioner is in cooling operation, the outdoor unit is in heating mode. Under other equal conditions, the higher the outdoor humidity, the greater the heat exchange will be, and the outdoor fan speed needs to be reduced to save resources. When the air conditioner is in heating operation, the outdoor unit is in cooling mode. The higher the outdoor humidity, the easier it is for the outdoor unit to frost. The outdoor fan speed needs to be reduced to slow down the frost speed of the outdoor unit, thereby saving resources and improving the air conditioner's energy efficiency. Therefore, whether the air conditioner is in cooling operation or heating operation, when the current outdoor temperature is greater than the set humidity value, it indicates that the outdoor humidity is high and the outdoor fan speed needs to be reduced. The set humidity value can be determined according to the air conditioner performance, the geographical region, and the season of use. For example, in the same summer, the same model of air conditioner in the southern region can have a corresponding set value of 55%, while in the northern region, the corresponding set value can be 60%. Generally, the set humidity value can be the upper limit of the comfortable humidity range for the human body.

[0041] Moreover, different operation modes of the outdoor unit have different ways of reducing the outdoor fan, that is, it is necessary to determine the current wind speed reduction strategy that matches the current outdoor unit operation mode in the current operation conditions. When the outdoor unit is in heating mode, it is necessary to reduce the speed of the outdoor fan to save resources. Therefore, the wind speed can be reduced according to humidity, and the outdoor fan speed can be reduced in gears or sections; and when the outdoor unit is in cooling mode, it is necessary to reduce the speed of the outdoor fan to slow down the frost speed of the outdoor unit. Therefore, the wind speed can be reduced according to time, that is, the wind speed reduction is a continuous and slow reduction. In this way, in some embodiments, determining the current wind speed reduction strategy that matches the current outdoor unit operation mode in the current operation conditions includes: when the current outdoor unit operation mode is a heating mode, the first wind speed reduction strategy that reduces the wind speed according to humidity is determined as the current wind speed reduction strategy; when the current outdoor unit operation mode is a cooling mode, the second wind speed reduction strategy that reduces the wind speed according to time is determined as the current wind speed reduction strategy.

[0042] The first wind speed reduction strategy may include: monitoring the outdoor humidity, and reducing the outdoor fan speed by a set ratio value for each increase in the outdoor humidity by a first set value. For example, reducing the outdoor fan speed by 5% for each increase in the outdoor humidity by 10 humidity values. Alternatively, reducing the outdoor fan speed by 3% for each increase in the outdoor humidity by 5 humidity values. Alternatively, reducing the outdoor fan speed by 1% for each increase in the outdoor humidity by 2 humidity values, 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 at a rate of 0.6% every 3 minutes, or reducing the outdoor fan speed at a rate of 1% every 10 minutes, etc.

[0044] Step 103: According to the current wind speed reduction strategy, the outdoor fan of the air conditioner is controlled to reduce its speed.

[0045] Among them, in some embodiments, when the current wind speed reduction strategy is the first wind speed reduction strategy, the controlling of the air conditioner outdoor fan to reduce speed includes: obtaining the current humidity difference between the monitored outdoor humidity and the current outdoor humidity, and reducing the current speed of the outdoor fan according to the current humidity difference and the first proportional value 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, when the outdoor humidity continues to increase, it is still necessary to continue to reduce the wind speed, that is, the monitored outdoor temperature can be determined as the current outdoor temperature, and the wind speed can continue to be reduced according to the humidity, that is, after the monitored outdoor temperature is determined as the current outdoor temperature, it is obviously greater than the set humidity value, and the outdoor temperature is continued to be monitored, and the humidity difference between the monitored outdoor humidity and the current outdoor humidity is continued to be calculated with the first proportional value between the reduction rate and the humidity difference to obtain the corresponding reduction rate, thereby, the current speed is * (1-reduction rate) to obtain the reduced speed. Among them, the first proportional value is the ratio between the reduction rate and the humidity difference, for example: the ratio between 5% and 10, the ratio between 3% and 5, and so on.

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

[0048] It can be seen that in the embodiment of the present disclosure, when the air conditioner meets the current operating conditions, a wind speed reduction strategy matching the outdoor unit operating mode is determined according to the outdoor humidity, and the air conditioner outdoor fan is controlled to reduce its speed according to the wind speed reduction strategy. When the outdoor unit is operating in the heating mode, the wind speed is reduced according to the humidity; and when the outdoor unit is operating in the cooling mode, the wind speed is reduced according to time. Therefore, different operating modes use different reduction strategies, which improves the air conditioner performance and achieves better energy efficiency while ensuring the reliability of the air conditioner operation and satisfying the user's comfort.

[0049] The operation flow is collected into a specific embodiment below to illustrate the control process for the outdoor unit of the air conditioner provided by the embodiment of the present invention.

[0050] In one embodiment of the present disclosure, when the air conditioner is in cooling mode, the set humidity value may be 60%, and the first proportional value may be a ratio between 5% and 10 humidity values.

[0051] Figure 2 FIG. 1 is a flow chart of a method for controlling an outdoor unit of an air conditioner provided by an embodiment of the present disclosure. Figure 2As shown in the figure, the air conditioner outdoor unit control process includes:

[0052] Step 201: One or more indoor air conditioners are operated in cooling mode, and the outdoor air conditioners are operated in heating mode.

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

[0054] Step 203: Determine whether Rh>60% is established. If yes, execute step 204; otherwise, this process ends.

[0055] Step 204: the air conditioner determines the first wind speed reduction strategy for reducing wind speed according to humidity as the current wind speed reduction strategy.

[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 obtains the current reduction rate according to the current humidity difference and the first proportional 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 determines the monitored outdoor temperature as the current outdoor temperature and returns to step 205 .

[0060] It can be seen that in this embodiment, when some indoor units or the entire machine are operating in cooling mode, the outdoor unit may be in heating mode. At this time, the speed of the outdoor fan is reduced according to the humidity. The greater the humidity increases, the greater the drop in the outdoor fan speed. While ensuring the reliability of the air-conditioning operation and satisfying the user's comfort, energy is saved and the better energy efficiency of the air-conditioning is ensured.

[0061] In one embodiment of the present disclosure, the air conditioner is operated in heating mode, 55%, and the second proportional value can be a ratio between 1% and 10 minutes.

[0062] Figure 3 FIG. 1 is a flow chart of a method for controlling an outdoor unit of an air conditioner provided by an embodiment of the present disclosure. Figure 3 As shown in the figure, the air conditioner outdoor unit control process includes:

[0063] Step 301: One or more indoor air conditioners are operated in heating mode, and the outdoor air conditioners are operated in cooling mode.

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

[0065] Step 303: Determine whether Rh>55% is established. If yes, execute step 304; otherwise, this process ends.

[0066] Step 304: the air conditioner determines the second wind speed reduction strategy for reducing the wind speed according to time as the current wind speed reduction strategy.

[0067] Step 305: The air conditioner obtains the current time difference, and obtains the current reduction rate according to the current time difference and the second proportional value, 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 operate at the current speed. Return to step 305.

[0069] It can be seen that in this embodiment, when some indoor units or the entire machine are operating in heating mode, the outdoor unit can be in cooling mode. At this time, the speed of the outdoor fan is slowly reduced according to time to slow down the frosting speed of the outdoor unit, thereby further saving energy while improving air conditioning performance and achieving better energy efficiency.

[0070] According to the above process for controlling an outdoor unit of an air conditioner, a device for controlling an outdoor unit of an air conditioner can be constructed.

[0074] The control module 430 is configured to control the air conditioner outdoor fan to reduce its speed according to the current wind speed reduction strategy.

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

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

[0077] The first determining unit is configured to determine, when the current operation mode of the outdoor unit is the heating mode, a first wind speed reducing strategy for reducing wind speed according to humidity as a current wind speed reducing strategy.

[0078] The second determining unit is configured to determine, when the current operation mode of the outdoor unit is the cooling mode, a second wind speed reducing strategy for reducing the wind speed according to time as the current wind speed reducing strategy.

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

[0080] The first control unit is configured to obtain a current humidity difference between the monitored outdoor humidity and the current outdoor humidity, reduce the current speed of the outdoor fan according to the current humidity difference and a first proportional value between the reduction rate and the humidity difference, and obtain a 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 according to the humidity.

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

[0083] The second control unit is configured to obtain the current speed of the outdoor fan; reduce the current speed according to the second proportional value of the reduction rate and the time before, and control the outdoor fan to run at the reduced speed.

[0084] The air conditioner outdoor unit control process used in the air conditioner outdoor unit control device is further described below in conjunction with the embodiments.

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

[0086] Figure 5 FIG. 1 is a schematic diagram of a structure of a control device for an outdoor unit of an air conditioner provided by an embodiment of the present disclosure. Figure 5 As shown, the control device 400 for an air conditioner outdoor unit 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 units are 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 units are in cooling mode, the operation determination module 440 can determine that the air conditioner is in cooling mode and meets the current operating conditions. At this time, the acquisition module 410 obtains the current outdoor humidity Rh.

[0088] In this way, Rh>60%, if the current outdoor unit operation mode is the heating mode, the first determination unit 421 in the determination module 420 can determine the first wind speed reduction strategy as the current wind speed reduction strategy. In this way, the first control unit 431 in the control module 430 obtains the monitored outdoor humidity, and obtains the current humidity difference between the monitored outdoor humidity and the current outdoor humidity, obtains the current reduction rate according to the current humidity difference and the first proportional value, and multiplies the current speed of the outdoor fan by (1-current reduction rate), and after obtaining the reduced speed, the reduced speed is determined as the current speed, and the outdoor fan is controlled to run at the current speed. In addition, the first control unit 431 also determines the monitored outdoor temperature as the current outdoor temperature, and continues to reduce the wind speed according to the humidity.

[0089] If Rh>60%, if the current outdoor unit operation mode is the cooling mode, the second determination unit 422 in the determination module 420 can determine the second wind speed reduction strategy as the current wind speed reduction strategy. In this way, the second control unit 432 in the control module 430 obtains the current time difference, and obtains the current reduction rate according to the current time difference and the second proportional value, and multiplies the current speed of the outdoor fan by (1-current reduction rate), and after obtaining the reduced speed, the reduced speed is determined as the current speed, and the outdoor fan is controlled to operate at the current speed.

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