[0074] Figure 1 This is a schematic flowchart of an air conditioner control method according to an embodiment of the present invention, such as...Figure 1 As shown, and with reference to Figures 2 to 7 The embodiment of the present application provides a control method of an air conditioner, the air conditioner 1 comprising two air outlet columns arranged side by side left and right, the two air outlet columns being arranged at intervals to form an air guide interval between the two air outlet columns.

[0075] The control method of the air conditioner comprises the following steps.

[0076] Step S301: acquiring a position distribution of indoor personnel and / or acquiring an indoor environment condition.

[0077] Step S302: controlling whether new air is introduced into at least one air outlet column and / or controlling an air outlet direction, an air outlet volume and / or an air outlet speed of at least one air outlet column and / or controlling a heat exchange capacity of a heat exchanger according to the position distribution of the indoor personnel and / or the indoor environment condition.

[0078] Specifically, the air conditioner 1 in the control method of the air conditioner is preferably a vertical air conditioner, comprising two air outlet columns arranged vertically and transversely, wherein a left air outlet column is arranged on the left and a right air outlet column is arranged on the right; an interval between the two air outlet columns is an air guide interval, when the air conditioner 1 starts to work, the two air outlet columns send air forward at the same time, and indoor air in the air guide interval is driven to flow forward by negative pressure, so that the indoor air is mixed with air blown out by the two air outlet columns and blown out together.

[0079] It should be noted that the control method of the present application preferably acquires the position distribution of the indoor personnel and acquires the indoor environment condition. It should be noted that the control method of the present application preferably controls whether new air is introduced into at least one air outlet column and controls an air outlet direction, an air outlet volume and an air outlet speed of at least one air outlet column and controls a heat exchange capacity of a heat exchanger according to the position distribution of the indoor personnel and the indoor environment condition.

[0080] Of course, in some alternative embodiments of the present application, the control method of the air conditioner of the present application comprises: acquiring a position distribution of indoor personnel or acquiring an indoor environment condition; controlling whether new air is introduced into at least one air outlet column or controlling an air outlet direction, an air outlet volume or an air outlet speed of at least one air outlet column or controlling a heat exchange capacity of a heat exchanger according to the position distribution of the indoor personnel or the indoor environment condition.

[0081] The control method of the air conditioner and the air conditioner 1 of the present application can control the air outlet direction, air outlet volume and / or air outlet speed of the two air outlet columns according to the position distribution of the indoor personnel and / or the indoor environment, and can also be understood as the air conditioner 1 can make the air outlet direction of the air outlet column face the indoor personnel according to the position distribution of the indoor personnel, and the air conditioner 1 can also control the air outlet volume and / or air outlet speed of the two air outlet columns according to the indoor environment, for example, making the air outlet volume and / or air outlet speed of the air outlet column close to the indoor personnel smaller, and making the air outlet volume and / or air outlet direction of the other air outlet column larger, so that the air conditioner 1 can blow soft air and quickly cool / heat at the same time, and the user experience is better.

[0082] As shown in the drawings, Figure 2 in some embodiments of the present application,

[0083] obtaining the position distribution of the indoor personnel, comprising:

[0084] obtaining the relative position of the indoor personnel and the air conditioner; the relative position includes that the indoor personnel is at the left front side of the air conditioner or at the front side of the air conditioner or at the right front side of the air conditioner;

[0085] obtaining the indoor environment, comprising:

[0086] obtaining the carbon dioxide concentration in the indoor environment, denoted as gas concentration;

[0087] obtaining the indoor environment temperature, and the difference between the indoor environment temperature and the target set temperature is denoted as temperature difference;

[0088] controlling whether at least one air outlet column introduces fresh air and / or controlling the air outlet direction, air outlet volume and / or air outlet speed of at least one air outlet column and / or controlling the heat exchange capacity of the heat exchanger according to the position distribution of the indoor personnel and / or the indoor environment, comprising:

[0089] when the gas concentration is greater than or equal to the preset concentration, making both air outlet columns introduce fresh air and blow out; and

[0090] controlling the air outlet direction, air outlet volume and / or air outlet speed of at least one air outlet column and controlling the heat exchange capacity of the heat exchanger according to the position distribution of the indoor personnel and / or the indoor environment temperature.

[0091] Specifically, the control method can obtain the carbon dioxide concentration in the indoor environment by setting a carbon dioxide concentration detection device. The specific process can be that the carbon dioxide concentration detection device detects the carbon dioxide concentration of the air in the indoor environment and sends a signal to the air conditioner 1, and the air conditioner 1 analyzes the signal and obtains the carbon dioxide concentration of the air in the indoor environment, that is, the gas concentration. The carbon dioxide detection device includes but is not limited to a carbon dioxide concentration detector or a carbon dioxide concentration sensor.

[0092] The control method can preferably detect the distance between the indoor personnel and the air conditioner 1 by the infrared detection device and send a signal to the air conditioner 1, and then the air conditioner 1 can analyze the distance between the indoor personnel and the air conditioner 1 according to the signal, which is recorded as the personnel distance. Further, the control method of the air conditioner can also detect the relative position between the indoor personnel and the air conditioner 1 by the infrared detection device, as the position distribution of the indoor personnel.

[0093] The control method can also obtain the position distribution of the indoor personnel according to the smart device with positioning function carried by the indoor personnel. The smart device with positioning function is connected to the air conditioner through a network and transmits data. The smart device with positioning function sends the positioning of the indoor personnel to a designated server or to the air conditioner 1, and then a program installed on the designated server or the air conditioner 1 calculates the distance between the indoor personnel and the air conditioner 1 and the relative position between the indoor personnel and the air conditioner 1.

[0094] The air conditioner 1 in the control method is also provided with a temperature detection device for obtaining the indoor environment temperature. After detecting the indoor environment temperature, the temperature detection device sends a signal to the air conditioner 1, and the air conditioner 1 analyzes and obtains the indoor environment temperature according to the signal, so as to calculate the temperature difference value in combination with the target set temperature. The temperature detection device can be a temperature sensor or a thermometer.

[0095] Further, when the gas concentration is greater than the preset concentration, the fresh air of the two air outlet columns is opened, and the air outlet direction, air outlet amount and / or air outlet speed of the air outlet column and the heat exchange capacity of the heat exchanger are controlled according to the position distribution of the indoor personnel and the indoor environment temperature. Such setting can purify the carbon dioxide in the indoor environment while controlling the air outlet direction and air outlet size of the two air outlet columns, thereby optimizing the user experience.

[0096] In some embodiments of the present application, the air outlet direction, air outlet amount and / or air outlet speed of at least one air outlet column and the heat exchange capacity of the heat exchanger are controlled according to the position distribution of the indoor personnel and / or the indoor environment temperature, including:

[0097] When the temperature difference value is greater than the preset difference value and the indoor personnel is at the left front side of the air conditioner 1:

[0098] The two air outlet columns blow mixed air of heat exchange air and fresh air.

[0099] The airflows flowing out of the first air outlets 13 of the two air outlet columns flow to the left front.

[0100] The air volume and / or air speed of the left air outlet column 11 are adjusted to be the first air volume and / or the first air speed, and the air volume and / or air speed of the right air outlet column 12 are adjusted to be the second air volume and / or the second air speed. The first air volume is smaller than the second air volume, and the first air speed is smaller than the second air speed.

[0101] The heat exchange capacity of the heat exchanger of the left air outlet column 11 is adjusted to be the first capacity, and the heat exchange capacity of the heat exchanger of the right air outlet column 12 is adjusted to be the second capacity. The first capacity is smaller than the second capacity.

[0102] Specifically, the preset temperature difference is 1-4°C, and preferably 2°C. When the temperature difference is greater than the preset temperature difference, it indicates that the indoor temperature difference is large. When the indoor personnel is at the left front side of the air conditioner 1, it indicates that there is indoor personnel at the left front side of the air conditioner 1. Therefore, when the indoor temperature difference is large and the indoor personnel is at the left front side of the air conditioner 1, the two air outlet columns blow mixed air of heat exchange air and fresh air to quickly reduce the temperature difference. The airflows blown out of the first air outlets 13 of the two air outlet columns flow to the left front, so that the heat exchange air can be blown to the indoor personnel at the left front of the air conditioner 1. At this time, the left air outlet column 11 is close to the indoor personnel, so the air volume and / or air speed of the left air outlet column 11 and the heat exchange capacity of the heat exchanger are smaller than those of the right air outlet column 12. It can also be understood that the air volume and / or air speed of the air outlet column close to the indoor personnel and the heat exchange capacity of the heat exchanger are small, so that the air feeling of the air outlet is soft and comfortable; the air volume and / or air speed of the air outlet column far away from the indoor personnel and the heat exchange capacity of the heat exchanger are large, so that the air conditioner 1 can quickly cool / heat. This setting can blow the mixed air to the indoor personnel while making the mixed air with soft air feeling first blow to the indoor personnel, so that the air conditioner 1 can make the air feeling of the air outlet more soft while quickly cooling / heating. Not only the user experience is better, but also the working efficiency of the air conditioner 1 is high.

[0103] Moreover, since the air guide interval is arranged between the two air outlet columns, when the air conditioner 1 starts to work, the two air outlet columns blow air to the left front while the indoor air in the air guide interval flows to the left front driven by negative pressure, so that the indoor air is mixed with the air blown out of the two air outlet columns and then blown out. This setting makes the temperature of the mixed air rise by 1-3°, and the feeling of the air blown on the human body is more soft and comfortable. It should be noted that the running mode of the air conditioner 1 when the two air outlets blow air to the left front is the first mode.

[0104] In some embodiments of the present application, according to the position distribution of the indoor personnel and / or the indoor environment temperature, the air outlet direction, air outlet volume and / or air outlet speed of the at least one air outlet column are controlled, and the heat exchange capacity of the heat exchanger is controlled, further comprising:

[0105] When the temperature difference is greater than the preset temperature difference, and the indoor personnel is at the front side of the air conditioner 1.

[0106] The two air outlet columns blow the mixed air of the heat exchange air and the fresh air.

[0107] The air flows out of the first air outlets 13 of the two air outlet columns flow to the front.

[0108] The air outlet volume and / or air outlet speed of the left air outlet column 11 are adjusted to the second air volume and / or second air speed, and the air outlet volume and / or air outlet speed of the right air outlet column 12 are adjusted to the second air volume and / or second air speed.

[0109] The heat exchange capacities of the heat exchangers of the left air outlet column 11 and the right air outlet column 12 are adjusted to the first capacity.

[0110] Specifically, when the temperature difference is greater than the preset temperature difference, it indicates that the indoor temperature difference is large. When the indoor personnel is at the front side of the air conditioner 1, it indicates that there is indoor personnel at the front side of the air conditioner 1. Therefore, when the indoor temperature difference is large and the indoor personnel is at the front side of the air conditioner 1, the two air outlet columns blow the heat exchange air to quickly reduce the temperature difference. The air flows out of the first air outlets 13 of the two air outlet columns flow to the front, so that the heat exchange air can blow to the indoor personnel located in front of the air conditioner 1. At this time, the air outlet volume and / or air outlet speed of the left air outlet column 11 and the right air outlet column 12 are adjusted to the relatively larger second air volume and / or second air speed, so that the air conditioner 1 can quickly cool / heat; at the same time, since the air guide interval is arranged between the two air outlet columns, when the air conditioner 1 starts to work, the two air outlet columns send air to the front, and at the same time, the indoor air in the air guide interval is driven to flow to the front by negative pressure, so that the indoor air is mixed with the air blown out of the two air outlet columns, so that the temperature of the mixed air flow rises by 1° to 3°, and the feeling of blowing on the human body is more soft and comfortable. This setting can make the heat exchange air blow to the indoor personnel while making the air feel softer and more comfortable, so that the air conditioner 1 can quickly cool / heat while making the air feel of its air outlet softer, which not only improves the user experience, but also improves the working efficiency of the air conditioner 1. It should be noted that the running mode of the air conditioner 1 when the two air outlets blow to the left front is the second mode.

[0111] In some embodiments of the present application, according to the position distribution of the indoor personnel and / or the indoor environment temperature, the air outlet direction, air outlet volume and / or air outlet speed of the at least one air outlet column are controlled, and the heat exchange capacity of the heat exchanger is controlled, further comprising:

[0112] when the temperature difference is greater than the preset temperature difference and the indoor personnel is at the right front side of the air conditioner 1.

[0113] The two air outlet columns blow mixed air of the heat exchange air and the fresh air.

[0114] The airflows flowing out of the first air outlets 13 of the two air outlet columns both flow to the right front.

[0115] The air outlet volume and / or air outlet speed of the right air outlet column 12 are adjusted to be the first air volume and / or the first air speed, and the air outlet volume and / or air outlet speed of the left air outlet column 11 are adjusted to be the second air volume and / or the second air speed.

[0116] The heat exchange capacity of the heat exchanger of the left air outlet column 11 is adjusted to be the second capacity, and the heat exchange capacity of the heat exchanger of the right air outlet column 12 is adjusted to be the first capacity.

[0117] Specifically, when the temperature difference is greater than the preset temperature difference, it indicates that the indoor temperature difference is large. When the indoor personnel is at the right front side of the air conditioner 1, it indicates that there is indoor personnel at the left front side of the air conditioner 1. Therefore, when the indoor temperature difference is large and the indoor personnel is at the right front side of the air conditioner 1, the two air outlet columns blow mixed air of the heat exchange air and the fresh air to quickly reduce the temperature difference. The airflows flowing out of the first air outlets 13 of the two air outlet columns flow to the right front, so that the mixed air of the heat exchange air and the fresh air can be blown to the indoor personnel at the left front side of the air conditioner 1. At this time, the right air outlet column 12 is close to the indoor personnel, so the air outlet volume and / or air outlet speed of the right air outlet column 12 and the heat exchange capacity of the heat exchanger are smaller than those of the right air outlet column 12. It can also be understood that the air outlet volume and / or air outlet speed of the air outlet column close to the indoor personnel and the heat exchange capacity of the heat exchanger are smaller, so that the air feeling of the air outlet is soft; the air outlet volume and / or air outlet speed of the air outlet column far away from the indoor personnel and the heat exchange capacity of the heat exchanger are larger, so that the air conditioner 1 can quickly cool / heat. This setting can make the mixed air with soft air feeling blow to the indoor personnel first while the mixed air of the heat exchange air and the fresh air is blown to the indoor personnel, so that the air conditioner 1 can make the air feeling of the air outlet more soft while quickly cooling / heating. The user experience is better, and the working efficiency of the air conditioner 1 is high.

[0118] Moreover, since the air guide interval is arranged between the two air outlet columns, when the air conditioner 1 starts to work, the two air outlet columns blow air to the right front at the same time, and the indoor air in the air guide interval flows to the right front under the action of negative pressure, so that the indoor air is mixed with the air blown by the two air outlet columns and is blown out. This setting makes the temperature of the mixed air rise by 1° to 3°, and the feeling of blowing on the human body is more soft and comfortable. It should be noted that the running mode of the air conditioner 1 when the two air outlets blow air to the left front is the third mode.

[0119] In some embodiments of the present application, the air outlet direction, the air outlet volume and / or the air outlet speed of the at least one air outlet column are controlled according to the position distribution of the indoor personnel and / or the indoor environment, and the method further comprises:

[0120] when the temperature difference is less than or equal to the preset temperature difference and greater than 0, and the indoor personnel is located at the left front side of the air conditioner 1.

[0121] the left air outlet column 11 blows the mixed air of the circulating air and the fresh air, and the right air outlet column 12 blows the mixed air of the heat-exchanged air and the fresh air.

[0122] the air flows out of the first air outlets 13 of the two air outlet columns flow to the left front side.

[0123] the air outlet volume and / or the air outlet speed of the left air outlet column 11 are adjusted to the first air outlet volume and / or the first air outlet speed, and the air outlet volume and / or the air outlet speed of the right air outlet column 12 are adjusted to the second air outlet volume and / or the second air outlet speed.

[0124] the heat exchange capacity of the heat exchanger of the right air outlet column 12 is adjusted to the second capacity.

[0125] Specifically, when the temperature difference is less than or equal to the preset temperature difference and greater than 0, it indicates that the indoor temperature difference is small, and thus the indoor environment temperature is relatively close to the target set temperature. When the indoor personnel is located at the left front side of the air conditioner 1, it indicates that there is indoor personnel at the left front side of the air conditioner 1. Therefore, when the indoor temperature difference is small and the indoor personnel is located at the left front side of the air conditioner 1, the air flows out of the first air outlets 13 of the two air outlet columns flow to the left front side, so that the air flow can blow to the indoor personnel located at the left front side of the air conditioner 1. At this time, the left air outlet column 11 is close to the indoor personnel, and the right air outlet column 12 is relatively far away from the indoor personnel. Therefore, the left air outlet column 11 blows the mixed air of the circulating air and the fresh air, and the air outlet volume and / or the air outlet speed of the left air outlet column 11 are relatively small, which can be understood as the air outlet column close to the indoor personnel blows the mixed air of the circulating air and the fresh air, and the air outlet volume and / or the air outlet speed thereof are small, so that the air feeling of the air outlet is soft. The air outlet column relatively far away from the indoor personnel blows the mixed air of the heat-exchanged air and the fresh air, and the air outlet volume and / or the air outlet speed thereof are large, and the heat exchange capacity of the heat exchanger is large, so that the indoor environment temperature can be maintained. This setting can blow the mixed air of the circulating air and the fresh air with relatively soft air feeling to the indoor personnel first while blowing the air flow to the indoor personnel, so that the air conditioner 1 can maintain the indoor environment temperature while making the air feeling of the air outlet more soft, which not only improves the user experience, but also improves the working efficiency of the air conditioner 1. The circulating air is preferably at least the air flow out of the air conditioner 1 without temperature reduction / heating treatment, so that the circulating air at least does not affect the indoor environment temperature.

[0126] And, since the air guiding interval is arranged between the two air outlet columns, when the air conditioner 1 starts to work, the two air outlet columns blow air to the left front at the same time, and the indoor air in the air guiding interval is driven to flow to the left front by the negative pressure, so that the indoor air is mixed with the air blown by the two air outlet columns and is blown out. The temperature of the mixed air flow is increased by 1-3 °, and the feeling of blowing on the human body is more soft and comfortable. It should be noted that the running mode of the air conditioner 1 when the two air outlets blow air to the left front is the fourth mode.

[0127] In some embodiments of the present application, according to the position distribution of the indoor personnel and / or the indoor environment temperature, the air outlet direction, the air outlet amount and / or the air outlet speed of the at least one air outlet column are controlled, and the heat exchange capacity of the heat exchanger is controlled, which further comprises:

[0128] When the temperature difference is less than or equal to the preset difference and greater than 0, and the indoor personnel is at the front side of the air conditioner 1.

[0129] The two air outlet columns blow mixed air of the heat exchange air and the fresh air.

[0130] The air flow flowing out of the first air outlet 13 of the two air outlet columns flows to the front.

[0131] The air outlet amount and / or the air outlet speed of the left air outlet column 11 are adjusted to the first air amount and / or the first air speed, and the air outlet amount and / or the air outlet speed of the right air outlet column 12 are adjusted to the first air amount and / or the first air speed.

[0132] The heat exchange capacity of the heat exchanger of the left air outlet column 11 and the right air outlet column 12 is adjusted to the first capacity.

[0133] Specifically, when the temperature difference is less than or equal to the preset temperature difference and greater than 0, it indicates that the indoor temperature difference is small, and the indoor environment temperature is relatively close to the target set temperature. When the indoor personnel is at the front side of the air conditioner 1, it indicates that there are indoor personnel at the front side of the air conditioner 1, and therefore, when the indoor temperature difference is small and the indoor personnel is at the front side of the air conditioner 1, the mixed air of the heat exchange air and the fresh air is blown out of the two air outlet columns. The air flow blown out of the first air outlet 13 of the two air outlet columns flows forward, so that the mixed air of the heat exchange air and the fresh air can be blown to the indoor personnel located in front of the air conditioner 1. At this time, the air outlet amount and / or the air outlet speed of the left air outlet column 11 and the right air outlet column 12 are adjusted to be relatively smaller first air amount and / or first air speed, so that the air conditioner 1 can maintain the current indoor environment temperature with less energy consumption; at the same time, since the air guide interval is arranged between the two air outlet columns, when the air conditioner 1 starts to work, the indoor air in the air guide interval is driven to flow forward by the negative pressure while the two air outlet columns send air forward, so that the indoor air is mixed with the air blown out of the two air outlet columns and blown out, so that the temperature of the mixed air flow rises by 1° to 3°, and the feeling of blowing on the human body is more comfortable. The above arrangement can blow the mixed air of the heat exchange air and the fresh air to the indoor personnel while making the air feel more comfortable, so that the air conditioner 1 maintains the current indoor environment temperature while making the air feel of its air outlet more comfortable, which not only provides better user experience, but also has high working efficiency. It should be noted that the running mode of the air conditioner 1 when the two air outlets blow air to the left front is the fifth mode.

[0134] In some embodiments of the present application, according to the position distribution of the indoor personnel and / or the indoor environment temperature, the air outlet direction, the air outlet amount and / or the air outlet speed of at least one air outlet column are controlled, and the heat exchange capacity of the heat exchanger is controlled, which further comprises:

[0135] When the temperature difference is less than or equal to the preset difference and greater than 0, and the indoor personnel is at the right front side of the air conditioner 1.

[0136] The left air outlet column 11 blows the mixed air of the heat exchange air and the fresh air, and the right air outlet column 12 blows the mixed air of the circulating air and the fresh air.

[0137] The air flow of the first air outlet 13 of the two air outlet columns flows to the right front.

[0138] The air outlet amount and / or the air outlet speed of the right air outlet column 12 are adjusted to be the first air amount and / or the first air speed, and the air outlet amount and / or the air outlet speed of the left air outlet column 11 are adjusted to be the second air amount and / or the second air speed.

[0139] The heat exchange capacity of the heat exchanger of the left air outlet column 11 is adjusted to be the second capacity.

[0140] Specifically, when the temperature difference is less than or equal to the preset temperature difference and greater than 0, it indicates that the indoor temperature difference is small, and the indoor environment temperature is relatively close to the target set temperature. When the indoor personnel is at the right front side of the air conditioner 1, it indicates that there is indoor personnel at the right front side of the air conditioner 1, and thus, when the indoor temperature difference is small and the indoor personnel is at the right front side of the air conditioner 1, the air flow blown by the first air outlet 13 of the two air outlet columns is made to flow to the right front, so that the air flow can be blown to the indoor personnel located at the right front of the air conditioner 1. At this time, the right air outlet column 12 is close to the indoor personnel, and the left air outlet column 11 is relatively far away from the indoor personnel; therefore, the right air outlet column 12 blows the mixed wind of the circulating wind and the fresh air, and the air outlet amount and / or the air outlet speed of the right air outlet column 12 are relatively small, that is, the air outlet column close to the indoor personnel blows the mixed wind of the circulating wind and the fresh air, and the air outlet amount and / or the air outlet speed thereof are small, so that the wind feeling of the air outlet is soft; the air outlet column relatively far away from the indoor personnel blows the mixed wind of the heat exchange wind and the fresh air, and the air outlet amount and / or the air outlet speed thereof are large, and the heat exchange capacity of the heat exchanger thereof is large, so that the indoor environment temperature can be maintained. Such a setting can make the mixed wind of the circulating wind and the fresh air with a relatively soft wind feeling blow to the indoor personnel first while the air flow is blown to the indoor personnel, so that the air conditioner 1 can maintain the indoor environment temperature while making the wind feeling of the air outlet softer, which not only improves the user experience, but also improves the working efficiency of the air conditioner 1.

[0141] In addition, since the air guide interval is arranged between the two air outlet columns, when the air conditioner 1 starts to work, the indoor air in the air guide interval is made to flow to the right front by the negative pressure while the two air outlet columns send air to the right front, so that the indoor air is mixed with the air blown by the two air outlet columns and is blown out. Such a setting makes the temperature of the mixed air flow rise by 1° to 3°, and the feeling of being blown on the human body is more comfortable. It should be noted that the running mode of the air conditioner 1 when the two air outlets blow air to the left front is the sixth mode.

[0142] In some embodiments of the present application, the front side of each air outlet column is provided with a first air outlet 13 in the shape of a vertical bar;

[0143] Each air outlet column comprises a wind guide surface connected with the first air outlet 13, and the wind guide surface is located on the side of the first air outlet 13 away from the other air outlet column; the wind guide surface has a second edge and a third edge, and the third edge is located in the oblique front of the second edge away from the first air outlet 13; the two air outlet columns are symmetrically arranged about a reference plane, and the reference plane is a vertical and front-back extending plane;

[0144] The front side of each air outlet column is further provided with a second air outlet 14 in the shape of a vertical bar, and the second air outlet 14 is arranged on the side of the first air outlet 13 away from the other air outlet column.

[0145] AsFigure 2 and Figure 6 As shown in FIG. 1, in some embodiments of the present application, the air outlet direction, air outlet volume and / or air outlet speed of the at least one air outlet column and the heat exchange capacity of the heat exchanger are controlled according to the position distribution of the indoor personnel and / or the indoor environment temperature, and the method further comprises:

[0146] When the temperature difference is less than or equal to 0.

[0147] The first air outlets 13 of the two air outlet columns are closed to only make the second air outlets 14 of the two air outlet columns blow the mixed air of the heat exchange air and the fresh air.

[0148] The air outlet volume and / or air outlet speed of the left air outlet column 11 is adjusted to a third air volume and / or a third air speed, and the air outlet volume and / or air outlet speed of the right air outlet column 12 is adjusted to a third air volume and / or a third air speed. The third air volume is less than the first air volume, and the third air speed is less than the first air speed.

[0149] The heat exchange capacity of the heat exchanger of the left air outlet column 11 and the right air outlet column 12 is adjusted to a third capacity, and the third capacity is less than the first capacity.

[0150] Specifically, when the temperature difference is less than or equal to 0, it indicates that the indoor environment temperature is less than the target set temperature. At this time, in order to prevent the indoor environment temperature from further decreasing, the two air outlet columns blow the mixed air of the heat exchange air and the fresh air, and the air outlet volume and / or air outlet speed of the two air outlet columns is adjusted to a third air volume and / or a third air speed, wherein the third air volume is the smallest air outlet volume relative to the first air volume and the second air volume, and the third air speed is the smallest air outlet speed relative to the first air speed and the second air speed, so as to avoid the indoor environment temperature from further changing and affecting the user experience. At the same time, the heat exchange capacity of the heat exchanger of the two air outlet columns is adjusted to the smallest third capacity, so as to save energy when the air conditioner 1 does not need to quickly cool / heat. It should be noted that the running mode of the air conditioner 1 when the two air outlets blow to the left front is the seventh mode.

[0151] In some embodiments of the present application, a first air guide structure is arranged at the first air outlet 13 of the left air outlet column 11, and a second air guide structure is arranged at the first air outlet 13 of the right air outlet column 12.
