[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 conditioner control method, an air conditioner control device and an air conditioner.

[0024] The air conditioner control method provided in this embodiment includes: step 100, obtaining the minimum speed of the outdoor fan; step 200, obtaining the first wind speed of the ambient wind entering the air conditioner outdoor unit; step 300, in a windless state, determining the first speed corresponding to the outdoor fan at the first wind speed; step 400, when the absolute value of the first speed is greater than or equal to the minimum speed, controlling the air conditioner to send a reminder to the target device and controlling the operation of the air conditioner.

[0025] Currently, the operation of air conditioner outdoor units fails to take into account the influence of outdoor ambient wind, resulting in discrepancies between the heat exchange effect and the actual heat exchange effect, and ineffective utilization of outdoor ambient wind. Therefore, the air conditioner control method provided in this embodiment promptly reminds the user to control the air conditioner operation based on the actual parameters of the outdoor ambient wind, thus rationally utilizing resources.

[0026] refer to Figure 1 Step 100: Obtain the minimum outdoor fan speed. This refers to the minimum speed of the outdoor fan under normal operation of the air conditioner. If the speed is lower than the minimum, the air conditioner will not operate. The parameters of different air conditioners vary, and the minimum outdoor fan speed of the air conditioner also varies. This can be obtained through testing or by querying the factory settings of the air conditioner.

[0027] Step 200, obtain the first wind speed of the ambient wind entering the air-conditioning outdoor unit; obtain the first wind speed of the outdoor ambient wind entering the air-conditioning outdoor unit through a wind speed detection device, and 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.

[0028] Step 300, in a windless state, determine the first rotational speed corresponding to the outdoor fan at the first wind speed; during the operation of the air conditioner, the rotational speed of the outdoor fan corresponds to a certain wind speed, and accordingly, in a windless state, the air conditioner needs to reach a certain wind speed, and the outdoor fan needs to reach a corresponding rotational speed; the outdoor ambient wind enters the first wind speed of the air conditioner outdoor unit, and when the outdoor fan is stopped, the first wind speed can drive the outdoor fan to rotate, and the rotational speed of the outdoor fan is the first rotational speed; that is, in a windless state, when the outdoor fan runs at the first rotational speed, the first wind speed can be achieved.

[0029] Furthermore, in step 400, when the absolute value of the first speed is greater than or equal to the minimum speed, the air conditioner is controlled to send a reminder to the target device and control the operation of the air conditioner. When the first speed is greater than or equal to the minimum speed, the outdoor fan is shut down and the air conditioner can operate normally to achieve heat exchange. The air conditioner is controlled to send a reminder to the target device to remind the target user that the first wind speed of the outdoor ambient wind entering the air conditioner outdoor unit is sufficient to drive the operation of the air conditioner. The target user can control the operation of the air conditioner based on the first wind speed and the first speed, thereby rationally utilizing natural resources to achieve heat exchange and save energy.

[0030] This embodiment obtains the parameters of the air conditioner by obtaining the minimum speed of the outdoor fan; obtains the first wind speed of the ambient wind entering the air conditioner outdoor unit through a wind speed detection device to understand the parameters of the ambient wind entering the air conditioner outdoor unit; determines the first speed of the outdoor fan to reach the first wind speed in a windless state based on the first wind speed of the outdoor ambient wind entering the air conditioner outdoor unit, and understands the speed at which the first wind speed of the ambient wind can drive the outdoor fan to rotate when the outdoor fan is stopped; further, when the first speed is greater than or equal to the minimum speed of the outdoor fan, the first wind speed entering the air conditioner outdoor unit can drive the operation of the air conditioner, and the air conditioner is controlled to send a reminder message to the target device to remind the target user that the first wind speed at this time can drive the operation of the air conditioner, so as to rationally utilize natural resources to control the operation of the air conditioner and realize heat exchange.

[0031] In one embodiment, the air conditioner sends a reminder message to the target device. When the target user receives the reminder message, he or she controls the operation of the air conditioner through an APP or an air conditioner remote controller as needed.

[0032] Based on the above embodiment, when the absolute value of the first speed is greater than or equal to the minimum speed, the air conditioner is controlled to send a reminder to the target device and the operation of the air conditioner is controlled, including: obtaining the start time of the air conditioner; within a preset time before the start time, when the absolute value of the first speed is greater than or equal to the minimum speed, the air conditioner is controlled to send a reminder to the target device; the compressor and the air conditioner indoor unit are controlled to operate, and the outdoor fan is controlled to stop.

[0033] This embodiment records the start-up time of the air conditioner multiple times to understand the target user's habit of using the air conditioner; this embodiment can also obtain the start-up time of the air conditioner through manual input by the target user.

[0034] In one embodiment, the start-up time of the air conditioner is obtained at 7 o'clock in the evening of the same day. Within a preset time period before 7 o'clock, such as within 60 minutes before the air conditioner is started, the first wind speed of the outdoor ambient wind entering the outdoor unit of the air conditioner is obtained, and in a windless state, the first wind speed corresponding to the first speed of the outdoor fan is determined; further, when the absolute value of the first speed is greater than or equal to the minimum speed of the outdoor fan, the first wind speed entering the air conditioner at this time can drive the normal operation of the air conditioner, and the air conditioner is controlled to send a reminder to the target device, reminding the target user to rationally utilize natural resources and control the operation of the air conditioner.

[0035] The first wind speed entering the air conditioner outdoor unit can exchange heat with the outdoor heat exchanger. After the target user confirms the operation of the air conditioner, the compressor and the air conditioner indoor unit are controlled to operate normally, and the outdoor fan is controlled to stop. While maintaining the normal operation of the air conditioner, the outdoor fan is controlled to stop, and the indoor environment temperature can be adjusted for the target user in advance. When the target user enters the room where the air conditioner is located, he or she is in a comfortable environment, and energy can also be saved. This control method rationally utilizes natural resources, adjusts the indoor environment for the target user in advance, improves user comfort, and saves energy.

[0036] On the basis of the above embodiment, further, the operation of the compressor and the indoor unit of the air conditioner is controlled, and the outdoor fan is controlled to stop, including: obtaining the indoor ambient temperature and the outdoor ambient temperature; obtaining the maximum frequency of the compressor; controlling the operating mode and operating temperature of the air conditioner according to the indoor ambient temperature and the outdoor ambient temperature; controlling the compressor to operate at a first frequency, and the first frequency is less than or equal to half of the maximum frequency.

[0037] This embodiment obtains the indoor ambient temperature of the room where the air conditioner is located through a temperature monitoring device to understand the current environmental parameters of the room where the air conditioner is located; obtains the outdoor ambient temperature through a temperature monitoring device to understand the outdoor environmental parameters; further, controls the operating mode and operating temperature of the air conditioner according to the indoor ambient temperature and the outdoor ambient temperature; for example, in winter, controls the air conditioner to operate in heating mode; in summer, controls the air conditioner to operate in cooling mode; further, sets the operating temperature of the air conditioner according to the relationship between the indoor ambient temperature and the preset temperature.

[0038] In this embodiment, the maximum frequency of the compressor is obtained through experiments, and the maximum frequency of the compressor can also be obtained through the factory settings of the compressor, thereby understanding the parameters of the compressor, wherein the maximum frequency of the compressor refers to the maximum frequency that the compressor can reach. If this frequency is exceeded, the compressor will not work normally.

[0039] Furthermore, the compressor is controlled to operate at a first frequency, wherein the first frequency of the compressor corresponds to the frequency of the compressor when the outdoor fan operates at a first wind speed, that is, the first wind speed of the outdoor fan entering the outdoor unit of the air conditioner, the first rotational speed of the outdoor fan, and the first frequency of the compressor correspond one to one, thereby ensuring the normal operation of the air conditioner, and the frequency of the compressor is less than or equal to half of the maximum frequency of the compressor, thereby saving energy.

[0040] On the basis of the above embodiment, further, in a windless state, the first rotational speed corresponding to the outdoor fan at the first wind speed is determined, including: inputting the first wind speed into a prediction model to obtain a first rotational speed corresponding to the first wind speed; wherein the prediction model is obtained by testing in a windless state, using the rotational speed of the outdoor fan as sample information and the wind speed corresponding to the rotational speed as a sample label.

[0041] In a windless state, at a first wind speed, the first rotational speed corresponding to the outdoor fan is obtained by establishing a prediction model through experiments; specifically, in a windless state, the wind speed corresponding to the outdoor fan at different rotational speeds is obtained, and then the relationship between the rotational speed of the outdoor fan and the wind speed is obtained, which is the prediction model. For example, in a windless state, the relationship between the wind speed and the rotational speed is F=KN, which is the prediction model; further, in a windless state, when the outdoor fan is running at a first wind speed F1, the first wind speed F1 is input into the prediction model to obtain the first rotational speed N1 of the outdoor fan, that is, N1=F1 / K.

[0042] In another embodiment, in a windless state, the relationship between wind speed and rotational speed is F = KN + m (m is a constant); further, in a windless state, when the outdoor fan is running at a first wind speed F1, the first wind speed F1 is input into the prediction model to obtain the first rotational speed N1 of the outdoor fan, that is, N1 = (F1-m) / K.

[0043] In this embodiment, the calculation method of the first speed is not specifically limited. It is limited according to the operating conditions of the outdoor fan. The calculation method of the first speed is different for different operating conditions, that is, the prediction model is determined based on the specific conditions of the outdoor fan speed and wind speed.

[0044] On the basis of the above embodiments, further, the air conditioner includes a shell and an outdoor heat exchanger, the shell is provided with a first air inlet, a second air inlet and an air outlet, the first air inlet and the second air inlet are respectively provided on two adjacent side walls of the shell, the air outlet is parallel to the first air inlet and perpendicular to the second air inlet; the outdoor heat exchanger is provided in the shell, and the outdoor heat exchanger is in contact with the external environment through the first air inlet, the second air inlet and the air outlet; obtaining a first wind speed of the ambient wind entering the air-conditioning outdoor unit includes: obtaining a second wind speed of the ambient wind entering the air-conditioning outdoor unit through the first air inlet; obtaining a third wind speed of the ambient wind entering the air-conditioning outdoor unit through the second air inlet; determining a first wind speed based on the second wind speed and the third wind speed, the first wind speed being equal to the sum of the second wind speed and the third wind speed.

[0045] 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.

[0046] In this embodiment, a wind speed detection device is set at the first air inlet to obtain the second wind speed F2 of the ambient wind entering the air-conditioning outdoor unit, wherein the second wind speed F2 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 second wind speed F2 is positive, that is, the second wind speed F2 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 second wind speed F2 is negative, that is, the second wind speed F2 is a negative value.

[0047] In this embodiment, a wind speed detection device is set at the second 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 second air inlet is the same as the air inlet direction of the second air inlet, the third wind speed F3 is positive, that is, the third wind speed F3 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 third wind speed F3 is negative, that is, the third wind speed F3 is a negative value.

[0048] Furthermore, the first wind speed is determined according to the second wind speed F2 and the third wind speed F3, that is, the first wind speed F1 is equal to the vector sum of the second wind speed F2 and the third wind speed F3, that is, F1 = F2 + F3.

[0049] On the basis of the above embodiment, obtaining the second wind speed of the ambient wind entering the air-conditioning outdoor unit through the first air inlet includes: obtaining the fourth 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; and determining the second wind speed based on the relationship between the fourth wind speed and the first ratio, the second wind speed being equal to the product of the fourth wind speed and the first ratio.

[0050] Obtain the fourth wind speed F4 of the ambient wind at the first air inlet, and understand the parameters of the ambient wind at the first air inlet, where the fourth wind speed F4 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.

[0051] Furthermore, the second wind speed F2 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 fourth wind speed F4 and the first ratio, that is, F3=F4×L2 / L1.

[0052] Based on the above embodiment, obtaining the third wind speed of the ambient wind entering the air-conditioning outdoor unit through the second air inlet includes: obtaining the fifth 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; determining the third wind speed based on the direction of the fifth wind speed and the relationship between the fifth wind speed and the second ratio.

[0053] Obtain the fifth wind speed F5 of the ambient wind at the second air inlet, and understand the parameters of the ambient wind at the second air inlet, where the fifth wind speed F5 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.

[0054] It is determined whether the direction of the fifth wind speed is consistent with the direction of the air inlet at the second air inlet, and the third wind speed is determined based on the relationship between the fifth wind speed F5 and the second ratio.

[0055] Further, the third wind speed is determined based on the direction of the fifth wind speed and the relationship between the fifth wind speed and the second ratio, including: when the direction of the fifth wind speed is positive, the third wind speed is equal to the product of the fifth wind speed and the second ratio; when the direction of the fifth wind speed is negative, the third wind speed is equal to 0.

[0056] 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 fifth wind speed F5 is positive, and the third wind speed F3 of the ambient wind from the second air inlet entering the air-conditioning outdoor unit is the product of the fifth wind speed F5 and the second ratio, that is, F3 = F5 × L3 / L1.

[0057] 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 fifth wind speed F5 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 fifth wind speed does not affect the heat exchange of the outdoor heat exchanger. The third wind speed is zero, that is, F3=0.

[0058] The first wind speed F1 of the ambient wind entering the air-conditioning outdoor unit is equal to the sum of the second wind speed F2 and the third wind speed F3, where F2 = F4×L2 / L1, F3 = F5×L3 / L1, that is, F1 = F4×L2 / L1+F5×L3 / L1, where F1, F4, and F5 are all vectors; determine the first speed corresponding to the outdoor fan when running at the first wind speed in a windless state.

[0059] Furthermore, based on the relationship between the absolute value of the first speed and the minimum speed of the outdoor fan, the air conditioner is controlled to send a reminder message to the target device, and the target user controls the operation of the air conditioner according to the reminder message, thereby rationally utilizing natural resources.
