[0037] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0038] Unless specifically stated otherwise, the relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0039] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0040] Technologies, methods and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods and equipment should be considered part of the authorization specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] Figure 1 FIG2 is a flow chart of an outdoor fan control method according to an embodiment of the present disclosure. In some embodiments, the following outdoor fan control method is executed by an outdoor fan control device.

[0044] In step 101, the current rotation direction and speed of the outdoor fan, as well as the current power supplied to the fan, are detected at a preset frequency.

[0045] It should be noted that, since how to detect the current rotation direction and speed of the outdoor fan and the current power supplied to the fan are not the inventive point of the present disclosure, they will not be described in detail here.

[0046] In step 102, based on the rotation direction and rotation speed, as well as the electric energy, it is determined whether the wind turbine can rotate in a second direction opposite to the preset first direction under the independent driving of the current wind force.

[0047] It should be noted that the fan speed is related to the fan's rotation direction, the amount of power received, and the current external wind force. Therefore, based on the rotation direction and speed, as well as the amount of power, the current wind force can be determined, and then it can be determined whether the fan can rotate in the second direction under the independent drive of the wind force. Since the above determination operation is well known to those skilled in the art, it will not be described in detail here.

[0048] For example, the preset first direction is clockwise, and the second direction is counterclockwise. For example, the fan rotates in the first direction as forward rotation, and rotates in the second direction as reverse rotation.

[0049] In step 103 , when the fan can rotate in the second direction, it is determined whether the rotation speed of the fan can be greater than the first speed value.

[0050] In step 104, when the rotation speed of the fan is capable of being greater than the first speed value, the fan is controlled to be in a first rotation mode, wherein in the first rotation mode, power is applied to the fan in a second direction so that the fan rotates in the second direction at a second speed value greater than the first speed value.

[0051] In some embodiments, when the fan speed cannot be greater than the first speed value, the fan is controlled to be in a third rotation mode, in which power is applied to the fan in the first direction so that the fan rotates in the first direction at a preset speed value.

[0052] It should be noted here that when the fan can rotate in the second direction and the fan speed cannot be greater than the first speed value, it indicates that the external wind force has little impact on the fan at this time. In this case, the fan is controlled to rotate in the first direction (i.e., forward rotation).

[0053] In some embodiments, when the fan cannot rotate in the second direction, the fan is controlled to be in a third rotation mode, in which power is applied to the fan in the first direction so that the fan rotates at a preset speed value in the first direction.

[0054] It should be noted here that the fan cannot rotate in the second direction, indicating that the current external wind force will not cause the fan to reverse. That is to say, only under the action of the current external wind force, the fan is in a stationary state or rotates in the first direction. In this case, the fan is controlled to rotate in the first direction (i.e., forward rotation).

[0055] like Figure 2 As shown, when the fan is capable of rotating in the second direction, if the fan speed X is greater than the first speed value A, that is, X>A, then power in the second direction (that is, reverse power) is applied to the fan so that the fan rotates in the second direction at a second speed value greater than the first speed value. If the fan speed X is not greater than the first speed value A, that is, X≤A, then power in the first direction (that is, forward power) is applied to the fan so that the fan rotates in the first direction at a preset speed value.

[0056] Accordingly, when the fan is capable of rotating in the second direction, the state of the fan is controlled as shown in Table 1.

[0057] Fan speed State Control X≤A Apply forward force X>A Apply reverse force

[0058] Table 1

[0059] In the outdoor fan control method provided in the above embodiment of the present disclosure, the fan can rotate in the second direction and the fan speed can be greater than the first speed value. This indicates that with the help of external wind force, the outdoor fan only needs to consume less electric energy to rotate at a higher speed in the second direction, thereby achieving heat dissipation of the condenser with the help of external wind force and effectively reducing power consumption.

[0060] In some embodiments, when the external wind force is strong, the fan can rotate in the second direction based on the independent drive of the wind force, and the rotation speed exceeds the second speed. In this case, the power supply to the fan is stopped so that the fan can fully utilize the external wind force to rotate in the second direction, thereby achieving heat dissipation of the condenser without consuming electrical energy.

[0061] For example, Figure 3As shown, when the fan can rotate in the second direction, a first speed value A and a second speed value B are preset in advance, and B > A. The state of the fan is controlled as follows:

[0062] 1) When the rotational speed X of the fan can be greater than the first speed value A, it is judged whether the rotational speed X of the fan can be greater than or equal to the second speed value B.

[0063] 2) When the rotational speed X of the fan can be greater than the first speed value A and cannot be greater than or equal to the second speed value B, that is, A < X < B, the fan is controlled to be in the first rotation mode, that is, a power in the second direction (i.e., reverse power) is applied to the fan so that the fan rotates in the second direction at the second speed value B.

[0064] 3) When the rotational speed X of the fan can be greater than or equal to the second speed value B, that is, X ≥ B, the fan is controlled to be in the second rotation mode, in which the power supply to the fan is stopped so that the fan operates entirely by means of the external wind force.

[0065] 4) When the rotational speed X of the fan cannot be greater than the first speed value A, that is, X ≤ A, a power in the first direction (i.e., forward power) is applied to the fan so that the fan rotates in the first direction at a preset speed value.

[0066] Correspondingly, when the fan can rotate in the second direction, the state control of the fan is shown in Table 2.

[0067] Fan speed State Control X≤A Apply forward force A<X<B Apply reverse force X≥B Stop applying power

[0068] Table 2

[0069] Compared with the embodiment shown in Table 1, in the embodiment shown in Table 2, when the fan can rotate in the second direction, if the rotational speed X of the fan satisfies X ≥ B, the power supply is stopped so that the fan operates entirely by means of the external wind force. Thus, the heat dissipation of the condenser can be achieved entirely by means of the external wind force, and the power consumption is avoided.

[0070] In some embodiments, in order to avoid the rotation mode of the fan from switching back and forth in the neighborhood of the first speed value A and the second speed value B due to changes in the external wind force, transition regions can be set respectively in the neighborhood of the first speed value A and the second speed value B, and the rotation mode of the fan is maintained unchanged within this transition region, so that the situation of the rotation mode of the fan switching back and forth can be effectively avoided.

[0071] For example, as Figure 4As shown, when the fan can rotate in the second direction, the first speed value A and the second speed value B are preset in advance, and B > A. The neighborhood of the first speed value A is the region [A1, A2], and the neighborhood of the second speed value B is the region [B1, B2]. The state of the fan is controlled as follows:

[0072] 1) When the rotational speed X of the fan can be greater than the first speed value A, it is judged whether the rotational speed X of the fan can be greater than the third speed value A2.

[0073] In some embodiments, the third speed value A2 is the sum of the first speed value A and the first parameter value Δ1. For example, A2 = A + Δ1.

[0074] 2) When the rotational speed X of the fan can be greater than the first speed value A and cannot be greater than the third speed value A2, that is, A < X ≤ A2, the current rotation mode of the fan remains unchanged. This effectively avoids the rotation mode of the fan from switching back and forth near A.

[0075] 3) When the rotational speed X of the fan can be greater than the third speed value A2, it is judged whether the rotational speed X of the fan can be greater than or equal to the fourth speed value B1.

[0076] In some embodiments, the fourth speed value B1 is the difference between the second speed value B and the second parameter value Δ2. For example, B1 = B - Δ2.

[0077] 4) When the rotational speed X of the fan can be greater than the third speed value and cannot be greater than or equal to the fourth speed value, that is, A2 < X < B1, the fan is controlled to be in the first rotation mode, that is, a power in the second direction (i.e., reverse power) is applied to the fan so that the fan rotates in the second direction at the second speed value B.

[0078] 5) When the rotational speed X of the fan can be greater than or equal to the fourth speed value B1 and cannot be greater than or equal to the second speed value B, that is, B1 < X < B, the current rotation mode of the fan remains unchanged. This effectively avoids the rotation mode of the fan from switching back and forth near the first speed value A.

[0079] 6) When the rotational speed X of the fan can be greater than or equal to the second speed value B, it is judged whether the rotational speed X of the fan can be greater than the fifth speed value B2.

[0080] In some embodiments, the fifth speed value B2 is the sum of the second speed value B and the third parameter value. For example, if the third parameter value is the same as the second parameter value, then B2 = B + Δ2.

[0081] 7) When the rotational speed X of the fan can be greater than the fifth speed value B2, i.e., X > B2, control the fan to be in the second rotation mode. In the second rotation mode, stop applying power to the fan so that the fan operates entirely by the external wind force.

[0082] 8) When the rotational speed X of the fan can be greater than or equal to the second speed value B and cannot be greater than the fifth speed value B2, i.e., B ≤ X ≤ B2, maintain the current rotation mode of the fan unchanged. This effectively avoids the fan's rotation mode from switching back and forth near the second speed value B.

[0083] 9) When the rotational speed X of the fan cannot be greater than the first speed value A, determine whether the rotational speed X of the fan can be greater than or equal to the sixth speed value A1.

[0084] In some embodiments, the sixth speed value A1 is the difference between the first speed value A and the fourth parameter value. For example, if the fourth parameter value is the same as the first parameter value, then A1 = A - Δ1.

[0085] 10) When the rotational speed X of the fan cannot be greater than or equal to the sixth speed value A1, control the fan to be in the third rotation mode. That is, X < A1, then apply power in the first direction (i.e., forward rotation power) to the fan so that the fan rotates at a preset speed value in the first direction.

[0086] 11) When the rotational speed X of the fan can be greater than or equal to the sixth speed value A1 and cannot be greater than the first speed value A, i.e., A1 ≤ X < A, maintain the current rotation mode of the fan unchanged. This effectively avoids the fan's rotation mode from switching back and forth near the second speed value A.

[0087] Correspondingly, when the fan can rotate in the second direction, the state control of the fan is shown in Table 3.

[0088] Fan speed State Control X<A1 Apply forward force A1≤X≤A2 Maintain the fan status unchanged <h2 style=";text-align:left;direction:ltr">A2 <X<B1 <h2 style=";text-align:left;direction:ltr"> Apply reverse force B1≤X≤B2 Maintain the fan status unchanged X>B2 Stop applying power

[0089] Table 3

[0090] Compared with the embodiment shown in Table 2, in the embodiment shown in Table 3, transition regions are respectively set in the neighborhoods of the first speed value A and the second speed value B, and the rotation mode of the fan is maintained unchanged within these transition regions, thereby effectively avoiding the occurrence of the situation where the rotation mode of the fan switches back and forth.

[0091] Figure 5 It is a schematic structural diagram of an outdoor fan control device according to an embodiment of the present disclosure. As Figure 5 shown, the outdoor fan control device includes a first processing module 51 and a second processing module 52.

[0092] The first processing module 51 is configured to detect the current rotation direction and speed of the outdoor fan, and the power currently provided to the fan at a preset frequency.

[0093] The second processing module 52 is configured to determine whether the fan can rotate in a second direction opposite to the preset first direction under the independent drive of the current wind force based on the rotation direction and rotation speed, as well as the electrical energy; if the fan can rotate in the second direction, determine whether the rotation speed of the fan can be greater than the first speed value; if the rotation speed of the fan can be greater than the first speed value, control the fan to be in the first rotation mode, wherein in the first rotation mode, power in the second direction is applied to the fan so that the fan rotates in the second direction at a second speed value greater than the first speed value.

[0094] In some embodiments, the second processing module 52 determines whether the fan speed can be greater than or equal to the second speed value when the fan speed can be greater than the first speed value. When the fan speed can be greater than the first speed value but cannot be greater than or equal to the second speed value, the fan is controlled to be in the first rotation mode, that is, power in the second direction (that is, reverse power) is applied to the fan so that the fan rotates in the second direction at the second speed value.

[0095] In some embodiments, if the fan speed can be greater than the first speed value, the second processing module 52 determines whether the fan speed can be greater than a third speed value, wherein the third speed value is greater than the first speed value and less than the second speed value. If the fan speed can be greater than the third speed value, the second processing module 52 determines whether the fan speed can be greater than or equal to a fourth speed value, wherein the fourth speed value is less than the second speed value and greater than the third speed value. If the fan speed can be greater than the third speed value but cannot be greater than or equal to the fourth speed value, the second processing module 52 controls the fan to be in the first rotation mode.

[0096] When the fan speed can be greater than the first speed value and cannot be greater than the third speed value, the second processing module 52 maintains the current rotation mode of the fan, thereby effectively preventing the fan rotation mode from switching back and forth around the first speed value.

[0097] When the fan speed is greater than or equal to the fourth speed value and cannot be greater than or equal to the second speed value, the second processing module 52 maintains the current rotation mode of the fan, thereby effectively preventing the fan rotation mode from switching back and forth around the second speed value.

[0098] In some embodiments, the third speed value is the sum of the first speed value and the first parameter value, and the fourth speed value is the difference between the second speed value and the second parameter value.

[0099] In some embodiments, when the rotation speed of the fan is greater than or equal to a second speed value, the second processing module 52 controls the fan to be in a second rotation mode, wherein power is stopped from being applied to the fan in the second rotation mode.

[0100] In some embodiments, when the fan speed can be greater than or equal to the second speed value, the second processing module 52 determines whether the fan speed can be greater than a fifth speed value, where the fifth speed value is greater than the second speed value. When the fan speed can be greater than the fifth speed value, the fan is controlled to be in the second rotation mode.

[0101] When the fan speed is greater than or equal to the second speed value and cannot be greater than the fifth speed value, the second processing module 52 maintains the current rotation mode of the fan, thereby effectively preventing the fan rotation mode from switching back and forth around the second speed value.

[0102] When the fan speed cannot be greater than the first speed value, the second processing module 52 controls the fan to be in a third rotation mode, wherein in the third rotation mode, power is applied to the fan in the first direction so that the fan rotates in the first direction at a preset speed value.

[0103] If the fan speed cannot be greater than the first speed value, the second processing module 52 determines whether the fan speed can be greater than or equal to a sixth speed value, where the sixth speed value is less than the first speed value. If the fan speed cannot be greater than or equal to the sixth speed value, the second processing module 52 controls the fan to be in the third rotation mode.

[0104] When the fan speed is greater than or equal to the sixth speed value and cannot be greater than the first speed value, the second processing module 52 maintains the current rotation mode of the fan, thereby effectively preventing the fan rotation mode from switching back and forth around the first speed value.

[0105] In some embodiments, the fifth speed value is the sum of the second speed value and the third parameter value, and the sixth speed value is the difference between the first speed value and the fourth parameter value.

[0106] In some embodiments, when the fan cannot rotate in the second direction, the fan is controlled to be in a third rotation mode, wherein in the third rotation mode, power is applied to the fan in the first direction so that the fan rotates at a preset speed value in the first direction.
