[0022] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] The following combination Figures 1 to 3 The present invention describes an air-conditioning outdoor unit control method, device, air-conditioning outdoor unit and electronic equipment.

[0024] The air conditioner outdoor unit control method provided in this embodiment includes: step 100, obtaining a first wind speed of ambient wind entering the air conditioner outdoor unit; step 200, obtaining the current speed of the outdoor fan, and determining a second wind speed at which the outdoor fan runs at the current speed in a windless state; step 300, determining a first speed corresponding to the outdoor fan at the first wind speed based on the current speed, the first wind speed, and the second wind speed; and step 400, controlling the operation of the outdoor fan according to the relationship between the absolute value of the first speed and the current speed.

[0025] Currently, the operation of air conditioner outdoor units fails to take into account the influence of outdoor ambient wind, resulting in a discrepancy between the outdoor heat exchange effect and the actual heat exchange effect, and ineffective utilization of the outdoor ambient wind. Therefore, the air conditioner outdoor unit control method provided in this embodiment controls the operation of the air conditioner outdoor fan based on the actual parameters of the outdoor ambient wind, thereby conserving resources while maintaining the current cooling or heating effect.

[0026] refer to Figure 1In step 100, a first wind speed of the ambient wind entering the outdoor unit of the air conditioner is obtained; the first wind speed of the outdoor ambient wind entering the outdoor unit of the air conditioner is obtained through a wind speed detection device to understand the parameters of the ambient wind, wherein the first wind speed is a vector with direction and magnitude. When the ambient wind is consistent with the air inlet direction of the air inlet, the first wind speed is a positive value; when the ambient wind is opposite to the air inlet direction of the air inlet, the first wind speed is a negative value.

[0027] Step 200, obtain the current speed of the outdoor fan, and determine the second wind speed of the outdoor fan running at the current speed in a windless state; by obtaining the current speed of the outdoor fan, understand the current operating status of the outdoor fan.

[0028] In a windless state, the air-conditioning outdoor unit is controlled to operate at different speeds, and the corresponding wind speed is obtained to determine the relationship between the speed and wind speed of the outdoor fan in a windless state; further, the second wind speed of the outdoor fan is determined when the air-conditioning outdoor fan operates at the current speed in a windless state.

[0029] Step 300, based on the current rotational speed, the first wind speed and the second wind speed, determines the first rotational speed corresponding to the outdoor fan at the first wind speed; this embodiment obtains the first wind speed of the ambient wind entering the air-conditioning outdoor unit, and the first wind speed can drive the outdoor fan to rotate, so as to obtain the first rotational speed of the outdoor fan corresponding to the first wind speed in a windless state, and then obtain the influence of the first wind speed entering the air-conditioning outdoor unit on the rotational speed of the outdoor fan.

[0030] Specifically, in a windless state, the wind speed of the outdoor fan at different speeds is obtained, and then the relationship between the speed and wind speed of the outdoor fan is obtained. For example, in a windless state, when the outdoor fan runs at the current speed N, the wind speed is the second wind speed F2, and F2=KN; further, in a windless state, when the outdoor fan runs at the first wind speed F1, the first speed N1 of the outdoor fan is equal to F1 / K, that is, N1=F1N / F2.

[0031] In another embodiment, in a windless state, the wind speed of the outdoor fan when running at the current speed N is a second wind speed F2, F2 = KN + m (m is a constant); further, in a windless state, when the outdoor fan runs at a first wind speed F1, the first speed N1 of the outdoor fan is equal to F1 / K, that is, N1 = F1N / F2-m.

[0032] In this embodiment, the calculation method of the first rotational speed is not specifically limited and is limited according to the operating conditions of the outdoor fan. The calculation method of the first rotational speed is different in different operating conditions.

[0033] Furthermore, in step 400, the operation of the outdoor fan is controlled according to the relationship between the absolute value of the first speed and the current speed; the first wind speed of the ambient wind entering the air-conditioning outdoor unit can affect the rotation of the air-conditioning outdoor fan, and by comparing the first speed with the current speed of the air-conditioning outdoor unit, the operation of the outdoor fan is controlled according to the comparison result, the ambient wind is reasonably utilized, and the heat exchange effect of the air-conditioning outdoor unit is improved, while also avoiding the waste of resources caused by unreasonable speed of the outdoor fan.

[0034] This embodiment obtains the first wind speed of the ambient wind entering the outdoor unit of the air conditioner through a wind speed detection device to understand the parameters of the ambient wind; determines the first speed of the outdoor fan when it is running at the first wind speed in a windless state based on the second wind speed, the current speed and the first wind speed when the outdoor fan is running at the current speed in a windless state, and understands the speed at which the ambient wind can drive the outdoor fan to rotate when the outdoor fan is stopped; further, based on the relationship between the absolute value of the first speed and the current speed of the outdoor fan, controls the operation of the outdoor fan, rationally utilizes natural resources, improves the heat exchange efficiency of the outdoor heat exchanger, and also avoids waste of resources caused by useless work generated by the outdoor fan.

[0035] On the basis of the above embodiment, further, according to the relationship between the absolute value of the first speed and the current speed, the operation of the outdoor fan is controlled, including: when the absolute value of the first speed is less than the current speed, the outdoor fan is controlled to operate at a second speed, and the second speed is equal to the difference between the current speed and the first speed; when the absolute value of the first speed is greater than the current speed, the outdoor fan is controlled to stop.

[0036] Specifically, the first wind speed of the ambient wind entering the air-conditioning outdoor unit is F1, the current speed of the outdoor fan is N, the second wind speed of the outdoor fan running at the current speed N in a windless state is F2, and when the wind speed of the outdoor fan running in a windless state is F1, the first speed of the outdoor fan is N1, that is, when the outdoor fan is stopped, the ambient wind enters the air-conditioning outdoor unit at the first wind speed F1, which can drive the first speed of the outdoor fan to N1.

[0037] When the direction of the ambient wind entering the air-conditioning outdoor unit is consistent with the air inlet direction of the air inlet, F1>0, which is a positive value; in a windless state, the second wind speed F2 when the outdoor fan runs at the current speed N is a positive value; further, the absolute value of the first speed N1 is compared with the current speed of the outdoor fan, and the operation of the outdoor fan is controlled according to the comparison result.

[0038] When the direction of the ambient wind is consistent with the air inlet direction, the first wind speed is positive, and the ambient wind entering the air-conditioning outdoor unit is conducive to improving the heat exchange efficiency of the outdoor heat exchanger. When the absolute value of the first speed N1 is less than the current speed, that is, the first speed at which the ambient wind drives the outdoor fan to rotate is less than the current speed N, without affecting the heat exchange of the outdoor heat exchanger, the speed of the outdoor fan is controlled to be reduced by N1 and run at the second speed N2. The second speed N2 is equal to the current speed N of the outdoor fan minus the absolute value (N1) of the first speed N1 of the outdoor fan, that is, N2 = N-N1, that is, the heat exchange of the outdoor heat exchanger is achieved through the ambient wind and the speed of the outdoor fan itself, saving resources.

[0039] When the absolute value of the first speed N1 is greater than the current speed, that is, the first speed at which the ambient wind drives the outdoor fan to rotate is greater than the current speed N, the outdoor ambient wind can meet the heat exchange demand of the outdoor heat exchanger. The air-conditioning outdoor unit continues to run, generating useless work and wasting resources. Based on this, in this embodiment, when the absolute value of the first speed N1 is greater than the current speed, the outdoor fan is controlled to stop, and the ambient wind is used to exchange heat for the outdoor heat exchanger.

[0040] When the direction of the ambient wind is opposite to the direction of the air inlet, the first wind speed is negative. When the outdoor fan is running, the ambient wind enters the air-conditioning outdoor unit and has a negative impact on the heat exchange of the outdoor heat exchanger. When the absolute value of the first speed N1 is less than the current speed N of the outdoor fan, the speed of the outdoor fan is controlled to increase the absolute value of the first speed N1 (-N1) and run at the second speed N2. The second speed N2 is equal to the current speed N of the outdoor fan minus the current speed N1 of the outdoor fan (N1 is a negative value at this time), that is, N2=N-N1.

[0041] When the absolute value of the first speed N1 is greater than the current speed, that is, the first speed N1 driven by the ambient wind to rotate the outdoor fan is greater than the current speed N, but the ambient wind is negative at this time, there is no need to control the speed of the outdoor fan to increase to resist the negative impact of the ambient wind. The outdoor fan is controlled to stop, and the ambient wind blows in from the air outlet and blows out from the air inlet after heat exchange to meet the heat exchange of the outdoor heat exchanger.

[0042] This embodiment controls the speed of the outdoor fan to increase or decrease by taking into account the relationship between the wind direction of the ambient wind entering the outdoor unit of the air conditioner and the absolute value of the first speed and the current speed of the outdoor fan, thereby rationally utilizing the ambient wind, improving the heat exchange effect of the outdoor heat exchanger, and avoiding waste of resources caused by unreasonable speed of the outdoor fan.

[0044] The outdoor unit of the air conditioner includes a shell and an outdoor heat exchanger. The shell is provided with an air inlet and an air outlet. The outdoor heat exchanger is arranged inside the shell and located between the air inlet and the air outlet. The outdoor ambient air enters from the air inlet, exchanges heat in the outdoor heat exchanger, and then blows out through the air outlet. Figure 2 The shell is provided with two air inlets, namely a first air inlet and a second air inlet, the first air inlet is arranged on the first side wall of the shell, and the second air inlet is arranged on the second side wall of the shell, the first side wall and the second side wall are adjacent to each other, and the first side wall and the second side wall are perpendicular to each other; further, the air outlet is arranged on the third side wall of the shell, the third side wall is parallel to the first side wall and perpendicular to the second side wall; that is, the outdoor ambient wind can enter the outdoor heat exchanger through the first air inlet and / or the second air inlet for heat exchange and be blown out from the air outlet, or it can enter the outdoor heat exchanger from the air outlet and then be blown out from the first air inlet.

[0045] In this embodiment, a wind speed detection device is set at the first air inlet to obtain the third wind speed F3 of the ambient wind entering the air-conditioning outdoor unit, wherein the third wind speed F3 is a vector. When the direction of the ambient wind entering the air-conditioning outdoor unit through the first air inlet is the same as the air inlet direction of the first air inlet, the third wind speed is positive, that is, the third wind speed is a positive value; when the direction of the ambient wind entering the air-conditioning outdoor unit through the first air inlet is opposite to the air inlet direction of the first air inlet, the third wind speed F3 is negative, that is, the third wind speed F3 is a negative value.

[0046] In this embodiment, a wind speed detection device is set at the second air inlet to obtain the fourth wind speed F4 of the ambient wind entering the air-conditioning outdoor unit, wherein the fourth wind speed F4 is a vector. When the direction of the ambient wind entering the air-conditioning outdoor unit through the second air inlet is the same as the air inlet direction of the second air inlet, the fourth wind speed F4 is positive, that is, the fourth wind speed F4 is a positive value; when the direction of the ambient wind entering the air-conditioning outdoor unit through the second air inlet is opposite to the air inlet direction of the second air inlet, the fourth wind speed F4 is negative, that is, the fourth wind speed F4 is a negative value.

[0047] Furthermore, the first wind speed is determined by the third wind speed F3 and the fourth wind speed F4, that is, the first wind speed F1 is equal to the vector sum of the third wind speed F3 and the fourth wind speed F4, that is, F1 = F3 + F4.

[0048] Based on the above embodiment, obtaining the third wind speed of the ambient wind entering the air-conditioning outdoor unit through the first air inlet includes: obtaining the fifth wind speed of the ambient wind at the first air inlet; obtaining the length of the first air inlet and the length of the outdoor heat exchanger, and determining a first ratio of the length of the first air inlet to the length of the outdoor heat exchanger; determining the third wind speed based on the relationship between the fifth wind speed and the first ratio, the third wind speed being equal to the product of the fifth wind speed and the first ratio.

[0049] Obtain the fifth wind speed F5 of the ambient wind at the first air inlet, and understand the parameters of the ambient wind at the first air inlet, where the fifth wind speed F5 is a vector; obtain the length L1 of the outdoor heat exchanger through the measuring device, the height of the outdoor heat exchanger is consistent with the height direction of the shell, obtain the length L2 of the first air inlet, that is, the length of the outdoor heat exchanger in contact with the external environment through the first air inlet, the width of the first air inlet is the same as the width of the outdoor heat exchanger, both are the height of the shell, determine the first ratio of the length L2 of the first air inlet to the length L1 of the outdoor heat exchanger, and understand the relationship between the length of the first air inlet and the length of the outdoor heat exchanger.

[0050] Furthermore, the third wind speed F3 of the ambient air at the first air inlet entering the air conditioner outdoor unit through the first air inlet is the product of the fifth wind speed F5 and the first ratio, that is, F3=F5×L2 / L1.

[0051] Based on the above embodiment, obtaining the fourth wind speed of the ambient wind entering the air-conditioning outdoor unit through the second air inlet includes: obtaining the sixth wind speed of the ambient wind at the second air inlet; obtaining the length of the second air inlet, and determining the second ratio of the length of the second air inlet to the length of the outdoor heat exchanger; and determining the fourth wind speed based on the direction of the sixth wind speed and the relationship between the sixth wind speed and the second ratio.

[0052] Obtain the sixth wind speed F6 of the ambient wind at the second air inlet, and understand the parameters of the ambient wind at the second air inlet, where the sixth wind speed F6 is a vector; obtain the length L3 of the second air inlet through the measuring device, that is, the length of the outdoor heat exchanger in contact with the external environment through the second air inlet, and the width of the second air inlet is the same as the width of the outdoor heat exchanger, both of which are the height of the shell. Determine the second ratio of the length L3 of the second air inlet to the length L1 of the outdoor heat exchanger, that is, L3 / L1, to understand the relationship between the length of the second air inlet and the length of the outdoor heat exchanger.

[0053] It is determined whether the direction of the sixth wind speed is consistent with the air inlet direction at the second air inlet, and the fourth wind speed is determined based on the relationship between the sixth wind speed F6 and the second ratio.

[0054] Furthermore, the fourth wind speed is determined based on the direction of the sixth wind speed and the relationship between the sixth wind speed and the second ratio, including: when the direction of the sixth wind speed is positive, the fourth wind speed is equal to the product of the sixth wind speed and the second ratio; when the direction of the sixth wind speed is negative, the fourth wind speed is equal to 0.

[0055] When the direction of the ambient wind at the second air inlet is the same as the air inlet direction of the second air inlet, the sixth wind speed F6 is positive, and the fourth wind speed F4 of the ambient wind from the second air inlet entering the air-conditioning outdoor unit is the product of the sixth wind speed F6 and the second ratio, that is, F4 = F6 × L3 / L1.

[0056] When the direction of the ambient wind at the second air inlet is opposite to the air inlet direction of the second air inlet, the sixth wind speed F6 is negative. Since the second air inlet is perpendicular to the air outlet, the outdoor ambient wind cannot enter through the air outlet and blow out from the second air inlet. The ambient wind at the sixth wind speed does not affect the heat exchange of the outdoor heat exchanger, and the fourth wind speed is zero, that is, F4=0.

[0057] The first wind speed F1 of the ambient wind entering the air-conditioning outdoor unit is equal to the sum of the third wind speed F3 and the fourth wind speed F4, where F3 = F5 × L2 / L1, F4 = F6 × L3 / L1, that is, F1 = F5 × L2 / L1 + F6 × L3 / L1, where F1, F5, and F6 are all vectors; determine the second wind speed of the outdoor fan when it runs at the current speed in a windless state, and further, based on the current speed, the first wind speed, and the second wind speed, determine the first speed N1 of the outdoor fan when the air-conditioning outdoor fan runs at the first wind speed F1, that is, the speed of the outdoor fan to reach the first wind speed F1.

[0058] When the first wind speed is positive, F1 is a positive value, and the outdoor ambient wind is beneficial to the heat exchange of the outdoor heat exchanger. When the absolute value of the first speed N1 (N1 is a positive value) is less than the current speed, the outdoor fan speed is controlled to decrease and run at the second speed N2 (N2=N-N1), so as to reasonably utilize the ambient wind and save energy. When the first wind speed is negative, F1 is a negative value, and the outdoor ambient wind has a negative impact on the outdoor heat exchanger. When the absolute value of the first speed N1 is less than the current speed, the outdoor fan speed is controlled to increase and run at the second speed N2 (N2=N-N1). At this time, N1 is a negative value, which resists the negative ambient wind and improves the heat exchange efficiency of the outdoor heat exchanger.

[0059] When the absolute value of the first rotational speed N1 is greater than the current rotational speed N, when the first wind speed is positive, the outdoor fan is controlled to stop, and the ambient air enters the air-conditioning outdoor unit from the first air inlet and / or the second air inlet, and is blown out from the air outlet after heat exchange, thereby realizing heat exchange of the outdoor heat exchanger; when the first wind speed F1 is negative, the outdoor fan is controlled to stop, and the ambient air enters the air-conditioning outdoor unit from the air outlet, and is blown out from the first air inlet after heat exchange, thereby realizing heat exchange of the outdoor heat exchanger; this embodiment rationally utilizes the ambient wind, controls the operation of the outdoor fan, improves the heat exchange efficiency of the outdoor heat exchanger, and avoids waste of resources.
