Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a control method of an air conditioner and an air conditioner. Background Art

[0002] With the rapid development of society and the continuous improvement of people's living standards, people's requirements for the quality of life are getting higher and higher. As an important electrical device, air conditioners have gradually entered thousands of households and are used by everyone. When a traditional air conditioner detects that the temperature in the room has reached the user's set temperature, it will stop the compressor from working, that is, it will shut down when the temperature reaches the set temperature. Some air conditioners with variable frequency functions will not shut down completely, but will also reduce the frequency when the room temperature reaches the set temperature and increase the frequency when the temperature rises. If the room temperature changes frequently, such as when the sun shines directly into the room in hot summer weather, the air conditioner will frequently start and stop the compressor or cause the compressor to continuously increase and decrease the frequency. At this time, frequent temperature shutdown or frequency conversion will cause large temperature fluctuations in the room, hot and cold, and the sound discontinuity of the air conditioner will cause a lot of noise, which will seriously affect the service life of the compressor and greatly reduce the reliability and safety of the air conditioner. Summary of the invention

[0003] Based on the above background, an object of the present invention is to provide a method for controlling an air conditioner that at least solves some of the above problems.

[0004] Another object of the present invention is to provide an air conditioner that solves the above-mentioned problems.

[0005] In particular, according to the first aspect of the present invention, the present invention provides a control method for an air conditioner, wherein the air conditioner comprises a first air outlet column and a second air outlet column arranged laterally at intervals, and a heat exchanger is respectively arranged in the first air outlet column and the second air outlet column.

[0006] The control method of the air conditioner includes: controlling the start-up of the air conditioner; detecting the ambient temperature of the operating environment of the air conditioner; judging whether the difference between the ambient temperature and the set temperature of the air conditioner is greater than a preset temperature difference threshold; if so, controlling both the first air outlet column and the second air outlet column to start heat exchange and blow out heat exchange airflows respectively; if not, controlling the first air outlet column to start heat exchange and blow out heat exchange airflows, and controlling the second air outlet column to stop heat exchange and blow out ambient temperature airflows.

[0007] Optionally, after the step of controlling the air conditioner to start, the method for controlling the air conditioner further includes: controlling the first air outlet column to discharge air in a preset direction; and controlling the second air outlet column to swing back and forth laterally to discharge air.

[0008] Optionally, the step of controlling the first air outlet column to discharge air in a preset direction includes: obtaining environmental characteristics of the air conditioner operating environment; determining a preset direction based on the environmental characteristics; adjusting the air outlet direction of the first air outlet column to the preset direction, so that the heat exchange airflow blown out by the first air outlet column forms an air curtain in the preset direction, and separates a temperature control space in the operating environment of the air conditioner.

[0009] Optionally, based on environmental characteristics, the step of determining a preset direction includes: confirming a high-impact area having the largest temperature difference with the set temperature of the air conditioner, and a side wall position in the operating environment that is far away from the air conditioner and adjacent to the high-impact area; setting the air outlet direction of the first air outlet column facing the side wall as a preset direction; or setting the air outlet direction of the first air outlet column toward the direction between the side wall and the high-impact area as a preset direction.

[0010] Optionally, the step of controlling the second air outlet column to swing back and forth laterally to discharge air includes: controlling the second air outlet column to swing back and forth laterally and toward the temperature adjustment space to discharge air.

[0011] Optionally, before the step of controlling the air conditioner to start, the air conditioner control method further includes: obtaining the positioning distance between the user and the air conditioner and a preset distance threshold; determining whether the positioning distance is less than the distance threshold; and if so, controlling the air conditioner to start.

[0012] Optionally, the step of obtaining the positioning distance between the user and the air conditioner includes: obtaining the positioning of a device interconnected with the air conditioner; and calculating the positioning distance according to the positioning of the device interconnected with the air conditioner.

[0013] Optionally, the device interconnected with the air conditioner includes: a mobile phone or a smart bracelet.

[0014] Optionally, when the difference between the ambient temperature and the set temperature of the air conditioner is greater than a temperature difference threshold, the control method of the air conditioner also includes: when the difference between the ambient temperature and the set temperature is equal to the temperature difference threshold, detecting the compressor frequency of the air conditioner and obtaining a preset frequency threshold; determining whether the compressor frequency is greater than the frequency threshold; if so, controlling the compressor to reduce the frequency to the frequency threshold.

[0015] According to another aspect of the present invention, the present invention provides an air conditioner, the air conditioner comprises a first air outlet column and a second air outlet column arranged in a transverse interval, and a heat exchanger is respectively arranged in the first air outlet column and the second air outlet column. The air conditioner also comprises a control device, the control device comprises a processor and a memory, wherein the memory stores a control program, and when the control program is executed by the processor, it is used to implement any of the above-mentioned control methods of the air conditioner.

[0016] The air conditioner of the present invention comprises a first air outlet column and a second air outlet column which are arranged at a horizontal interval, and a heat exchanger is arranged in the first air outlet column and the second air outlet column respectively, so that the first air outlet column and the second air outlet column can independently discharge air without interfering with each other and control whether the air flow is a heat exchange air flow. According to the control method of the air conditioner of the present invention, when the temperature difference between the ambient temperature and the set temperature of the air conditioner is large, the first air outlet column and the second air outlet column blow the heat exchange air flow at the same time to reduce the temperature difference; when the temperature difference between the ambient temperature and the set temperature of the air conditioner is small, only the first air outlet column blows the heat exchange air flow to provide cooling or heat, and the second air outlet column blows the ambient temperature air flow to increase air circulation. When the ambient temperature approaches the set temperature of the air conditioner, with the help of the cooling or heat provided by the first air outlet column and the ambient temperature air flow blown by the second air outlet column, the ambient temperature can be better maintained near the set temperature of the air conditioner, and at the same time, the compressor of the air conditioner only needs to continuously provide a certain amount of cooling or heat to the first air outlet column, without frequent start and stop or continuous frequency conversion.

[0017] Furthermore, the first air outlet column is controlled to discharge air in a preset direction, and the preset direction corresponds to the area with a greater impact on the ambient temperature. Through the wind curtain formed by the directional air discharge of the first air outlet column, this area is isolated from the temperature control space, thereby significantly reducing the temperature impact of the area on the temperature control space and making the temperature in the temperature control space more stable.

[0018] Furthermore, the air conditioner also has the function of automatic start-up.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0031] Figure 1 is a schematic diagram of an air conditioner 10 according to an embodiment of the present invention.

[0032] refer to Figure 1 As shown, the air conditioner 10 of this embodiment includes a first air outlet column 12 and a second air outlet column 14 which are arranged laterally at intervals, and a heat exchanger is respectively arranged in the first air outlet column 12 and the second air outlet column 14, so that the first air outlet column 12 and the second air outlet column 14 can independently discharge air without interfering with each other and control whether the outlet air flow is a heat exchange air flow.

[0033] exist Figure 1In the air conditioner 10 shown, the first air outlet column 12 and the second air outlet column 14 are fixed relative to the shell of the air conditioner 10, but longitudinally extending air guide plates are provided at their respective air outlets. By adjusting the rotation position of the air guide plates, the first air outlet column 12 and the second air outlet column 14 can adjust their own air outlet directions. At the same time, in other optional embodiments, the first air outlet column 12 and / or the second air outlet column 14 can be rotatably arranged on the air conditioner 10, so that the air outlet direction can be adjusted by rotating the column. It can be understood that the air outlets of the first air outlet column 12 and the second air outlet column 14 are arranged on their side walls rather than on the top or bottom surfaces, and the air outlets are generally as follows: Figure 1 It is schematically formed along the length direction of the first air outlet column 12 and the second air outlet column 14 .

[0034] Figure 2 1 is a flow chart of a control method of an air conditioner 10 according to an embodiment of the present invention.

[0035] refer to Figure 2 As shown, the control method of the air conditioner 10 generally includes:

[0036] Step S202, controlling the air conditioner 10 to start;

[0037] Step S204, detecting the ambient temperature of the operating environment of the air conditioner 10;

[0038] Step S206, determining whether the difference between the ambient temperature and the set temperature of the air conditioner 10 is greater than a preset temperature difference threshold;

[0039] If yes, execute step S208 to control the first air outlet column 12 and the second air outlet column 14 to start heat exchange and blow out heat exchange airflow respectively;

[0040] If not, step S210 is executed to control the first air outlet column 12 to start heat exchange and blow out heat exchange airflow, and control the second air outlet column 14 to stop heat exchange and blow out ambient temperature airflow.

[0041] The preset temperature difference threshold can be used to define the ambient temperature when the second air outlet column 14 of the air conditioner 10 switches between the working modes of blowing heat exchange airflow and blowing ambient temperature airflow. The set temperature of the air conditioner 10 is the temperature actively set by the user, which often reflects the user's ideal ambient temperature in the current environment. When the difference between the ambient temperature and the set temperature of the air conditioner 10 is greater than the temperature threshold, the first air outlet column 12 and the second air outlet column 14 blow out the heat exchange airflow at the same time, for example, blowing cooling airflow in summer and blowing heating airflow in winter, so as to efficiently adjust the ambient temperature to approach the set temperature of the air conditioner 10. When the difference between the ambient temperature and the set temperature of the air conditioner 10 is not greater than (equal to or less than) the temperature threshold, only the first air outlet column 12 blows out the heat exchange airflow, and the second air outlet column 14 directly blows the ambient temperature airflow sucked from the air inlet of the air conditioner 10 without heat exchange by the heat exchanger (that is, the ambient temperature airflow is the airflow with a temperature equal to or close to the ambient temperature). At this time, the heat exchange airflow provided by the first air outlet column 12 is used to further adjust the ambient temperature. The evaporator of the first air outlet column 12 is used to provide cold or heat to the environment to make the ambient temperature further approach the set temperature of the air conditioner 10. At the same time, the ambient warm air flow provided by the second air outlet column 14 is used to stir the ambient air to increase the air circulation in the environment. On the one hand, it helps to distribute the cold or heat carried by the heat exchange airflow to various places. On the other hand, it can also form ambient wind with suitable temperature, improve the comfort of users in the environment, and continue to reduce and control the ambient temperature when the users are not directly blown by the heat exchange airflow.

[0042] Since the air conditioner 10 continues to blow heat exchange airflow during this period, even when the ambient temperature is highly close to the set temperature of the air conditioner 10 (usually it can be understood that the ambient temperature is equal to the set temperature. For example, when the difference between the two is less than 0.5°C, it can be rounded off to consider that the ambient temperature is equal to the set temperature, or that the ambient temperature is highly close to the set temperature), the first air outlet column 12 is also continuously blowing heat exchange airflow to continue to provide cooling or heat to the environment, and the second air outlet column 14 is blowing ambient temperature airflow at the same time. The compressor of the air conditioner 10 does not need to be frequently started and stopped or continuously changed in frequency, but only needs to work continuously and provide a certain amount of cooling or heat.

[0043] Figure 3 FIG. 1 is a flow chart of a control method of an air conditioner 10 according to another embodiment of the present invention.

[0044] refer to Figure 3 As shown, in some optional embodiments, the control method of the air conditioner 10 includes not only the control of the outlet air flow temperature as described above, but also the control of the outlet air direction. Specifically:

[0045] Step S302, control the air conditioner 10 to start

[0046] Step S304, controlling the first air outlet column 12 to discharge air in a preset direction;

[0047] Step S306, controlling the second air outlet column 14 to swing back and forth horizontally to discharge air.

[0048] It can be understood that the above-mentioned step of controlling the air outlet direction is performed after the air conditioner 10 is started, and can be performed simultaneously with the step of controlling the air outlet air flow temperature, that is, steps S304 to S306 can be performed before or after steps S204 to S210, or can be performed simultaneously with steps S204 to S210. In other words, the air conditioner 10 can control the air outlet direction before or after controlling the air outlet air flow temperature, or can control the air outlet air flow temperature and the air outlet direction at the same time.

[0049] Among them, there is no specific execution order for steps S304 to S306, that is, after the air conditioner 10 is started, the air outlet directions of the first air outlet column 12 and the second air outlet column 14 can be adjusted in sequence, or the air outlet direction of the first air outlet column 12 can be adjusted while the second air outlet column 14 swings to discharge air.

[0050] In the above embodiment, the first air outlet column 12 blows the heat exchange airflow in a direction toward the preset direction, and the second air outlet column 14 swings back and forth horizontally to discharge air, and switches to blow the heat exchange airflow or the ambient temperature airflow according to the ambient temperature. In particular, when the difference between the ambient temperature and the set temperature of the air conditioner 10 is not greater than the preset temperature difference threshold, or further, when the ambient temperature is highly close to the set temperature of the air conditioner 10, since the heat exchange airflow blown by the first air outlet column 12 is blown in a direction toward the preset direction, the second air outlet column 14 swings to discharge air while blowing the ambient temperature airflow. By adjusting the preset direction, the air conditioner 10 can effectively prevent users in the environment from being directly blown by the heat exchange airflow, and at the same time, since the ambient air is continuously stirred by the ambient temperature airflow blown by the swinging second air outlet column 14, the user will not feel bored.

[0051] Even when the ambient temperature approaches the set temperature of the air conditioner 10, although the first air outlet column 12 still blows a heat exchange airflow with a temperature difference with the ambient temperature, the user will not actively turn off the air conditioner 10 or adjust the set temperature of the air conditioner 10 because the airflow temperature felt by the user is mainly the ambient temperature airflow blown by the second air outlet column 14. The control method of the air conditioner 10 in the above embodiment not only does not require active control of frequent start and stop or continuous frequency conversion of the compressor, but also further avoids the start and stop or frequency conversion of the compressor caused by the user issuing a control command.

[0052] In order to further improve the control effect of the air conditioner 10 on the ambient temperature, in some optional embodiments, the air conditioner 10 determines the preset direction in the following manner: obtain the environmental characteristics of the operating environment of the air conditioner 10; determine the preset direction based on the environmental characteristics; adjust the air outlet direction of the first air outlet column 12 to the preset direction, so that the heat exchange airflow blown out by the first air outlet column 12 forms an air curtain in the preset direction, and separates a temperature control space in the operating environment of the air conditioner 10.

[0053] The environmental characteristics of the operating environment of the air conditioner 10 may include the environmental layout in the operating environment, which usually refers to the room layout for a household air conditioner 10, i.e., the position of the room walls and the position of the air conditioner 10 itself in the room. The environmental characteristics may also include the position of doors and windows and the position of heat sources (or cold sources), and may also include the position of furniture.

[0054] Environmental characteristics can be obtained in the following manner: a camera is provided to the air conditioner 10, and the camera is used to collect images of the surrounding environment. By distinguishing features such as walls, doors and windows, and furniture in the image, specific environmental characteristics can be obtained. If the location of a heat source (or cold source) needs to be obtained, an infrared sensor device can be provided. In addition, the user can also input information on the operation panel of the air conditioner 10 or other external devices (such as using a mobile phone APP) to enable the air conditioner 10 to obtain environmental characteristics of the surrounding environment (such as which side of the room has doors and windows, etc.). It can be understood that the specific environmental characteristics acquisition methods are not limited to the above-mentioned ones, and will not be repeated here.

[0055] Based on the acquired environmental characteristics, the air conditioner 10 can identify the user's main activity space as the temperature-controlled space, and make the first air outlet column 12 of the air conditioner 10 discharge air in a preset direction and form a wind curtain, using the wind curtain to separate the temperature-controlled space from other specific areas, while the second air outlet column 14 swings to discharge air toward the temperature-controlled space.

[0056] Since the insulation effect of doors and windows is obviously not as good as that of walls, even if the doors and windows are not opened, when the temperature difference between indoor and outdoor is too large, heat exchange is easy to occur at the doors and windows, resulting in indoor cold or heat loss and outdoor heat or cold inflow. Especially in the hot summer, windows or balconies exposed to direct sunlight are more susceptible to heat invasion. In winter, the frequent air leakage problems of windows or balconies will also affect the user's living comfort.

[0057] Since users are accustomed to placing the air conditioner 10, especially the cabinet air conditioner 10 placed on the ground, near the corner of the room so that it will not affect the placement of other furniture such as sofas, and the air flow can radiate a large area in the room. When the air conditioner 10 in the above embodiment is set near doors, windows or balconies, by adjusting the preset direction, the air conditioner 10 can effectively isolate areas such as doors, windows, balconies and the temperature-controlled space, thereby preventing the heat or cold intrusion of these areas into the room from affecting the ambient temperature in the temperature-controlled space.

[0058] Specifically, according to the environmental characteristics, the step of determining the preset direction includes: confirming the high-impact area with the largest temperature difference from the set temperature of the air conditioner 10, and the side wall position in the operating environment that is far away from the air conditioner 10 and adjacent to the high-impact area; setting the air outlet direction of the first air outlet column 12 facing the side wall as the preset direction; or setting the air outlet direction of the first air outlet column 12 toward the direction between the side wall and the high-impact area as the preset direction.

[0059] Figure 4 is a schematic diagram of an operating environment of an air conditioner 10 according to an embodiment of the present invention.

[0060] Figure 4 The arrows indicate the air outlet directions of the first air outlet column 12 and the second air outlet column 14, wherein the first air outlet column 12 is close to the high-impact area B and makes the blown heat exchange air flow form a wind curtain separating the high-impact area B and the temperature-controlled space A, while the second air outlet column 14 swings back and forth toward the temperature-controlled space A to discharge air.

[0061] refer to Figure 4 As shown, since doors, windows, balconies and other areas tend to exchange more heat with the outdoor environment, the high-impact area B usually corresponds to the area where the doors, windows or balconies are located. After confirming the location of the high-impact area B, the side wall position away from the air conditioner 10 and adjacent to the high-impact area B is confirmed, which is usually the side wall opposite to the side wall close to the air conditioner 10.

[0062] The preset direction of the first air outlet column 12 can be as follows: Figure 4 As shown, it is arranged to face this side wall, or toward between this side wall and high-impact area B such as doors, windows, and balconies, so that the wind curtain blown out by the first air outlet column 12 toward this fixed direction can separate the high-impact area B from the temperature-controlled space A, preventing the heat or cold that invades the room from the high-impact area B from affecting the temperature-controlled space A that is being cooled or heated.

[0063] Furthermore, since the first air outlet column 12 is continuously blowing heat exchange airflow, for example, in summer, the first air outlet column 12 blows cooling airflow, and the heat from the outside environment that invades the room from the high-impact area B will be neutralized by the cold carried by the wind curtain formed by the first air outlet column 12. As long as the wind speed and the cold carried by the first air outlet column 12 are reasonably adjusted, the heat that invades the room from the high-impact area B will not affect the temperature-controlled space A on the other side of the wind curtain. In winter, the first air outlet column 12 blows heating airflow, which can neutralize the cold that invades the room from the high-impact area B.

[0064] In particular, in some optional embodiments, the air outlet direction of the second air outlet column 14 is set to be non-intersecting with the preset direction of the first air outlet column 12, that is, during the swinging process of the second air outlet column 14 toward the first air outlet column 12, the farthest position that can be swung to is the position where the air outlet direction is parallel to the preset direction of the first air outlet column 12. In this way, the air outlet airflow of the second air outlet column 14 during the reciprocating swinging process will not interfere with the air curtain formed by the first air outlet column 12.

[0065] It can be understood that in the above embodiment, the definition of the first air outlet column 12 and the second air outlet column 14 is based on the environmental characteristics of the operating environment of the air conditioner 10 rather than the relative position relationship between the first air outlet column 12 and the second air outlet column 14 on the air conditioner 10, that is, the first air outlet column 12 is relatively closer to the high-impact area B, and the second air outlet column 14 is swung toward the temperature-controlled space A during the air outlet process (without passing through the air curtain formed by the first air outlet column 12). Therefore, according to the specific location of the air conditioner 10 in the environment and the environmental characteristics of the operating environment of the air conditioner 10, the first air outlet column 12 and the second air outlet column 14 of the same air conditioner 10 may also change.

[0066] Figure 5 FIG. 1 is a flow chart of a control method of an air conditioner 10 according to another embodiment of the present invention.

[0067] In order to make the air conditioner 10 more intelligent and start the air conditioner in advance to lower the ambient temperature when the user needs it so that the user is not directly blown by the hot air flow, in some optional implementations, the air conditioner 10 is started based on the following control method:

[0068] Step S502, obtaining the positioning distance between the user and the air conditioner 10 and a preset distance threshold;

[0069] Step S504, determining whether the positioning distance is less than a distance threshold;

[0070] If yes, execute step S506 to control the air conditioner 10 to start.

[0071] For office workers who leave early and return late, the air conditioner 10 needs to be turned off during the absence to save electricity. However, if the air conditioner 10 is turned on after arriving home, the ambient temperature will take some time to adjust to the ideal temperature. During this period, the user needs to endure the unsuitable ambient temperature and the direct blowing of the heat exchange airflow. In order to improve the comfort of the user at home, the control method of the air conditioner 10 also includes obtaining the positioning distance between the user and the air conditioner 10, and by comparing it with the preset distance threshold, it can be determined whether the user is on the way home. For example, for a user whose workplace is 10 kilometers away from home, the distance threshold is preset to 5 kilometers. When the user enters this range from outside the 5-kilometer range, it usually means that the user is on the way home. At this time, the air conditioner 10 is controlled to start, and the air conditioner 10 can adjust the indoor ambient temperature in advance. When the user arrives home, the air conditioner 10 often has adjusted the ambient temperature to a difference with the set temperature of the air conditioner 10 that is less than the preset temperature difference threshold. At this time, the air outlet airflow of the second air outlet column 14 reciprocatingly swinging out of the air is also the ambient temperature airflow, and the user will not be directly blown by the heat exchange airflow.

[0072] The distance threshold can be set by the user according to the distance between the workplace or the place of frequent visits and the home, and the specific parameter range is relatively flexible. At the same time, the preset temperature difference threshold of the air conditioner 10 can also be flexibly set by the user, and the default temperature difference threshold parameter can be set to 3°C.

[0073] The positioning distance between the user and the air conditioner 10 can be obtained through a device that can be interconnected with the air conditioner 10. For example, the user uses a mobile phone APP to bind the air conditioner 10, and the positioning function of the mobile phone can be used to obtain the positioning distance between the user and the air conditioner 10. In addition, a smart bracelet or other device can also be used to interconnect with the air conditioner 10, which is not limited here.

[0074] When the heat exchanger of the second air outlet column 14 stops, that is, the second air outlet column 14 switches from blowing the heat exchange airflow to blowing the ambient temperature airflow, the air conditioner 10's demand for supply of cooling or heat also decreases accordingly. Therefore, in some optional embodiments, when the difference between the ambient temperature and the set temperature of the air conditioner 10 is greater than the temperature difference threshold, the control method of the air conditioner 10 further includes: when the difference between the ambient temperature and the set temperature is equal to the temperature difference threshold, detecting the compressor frequency of the air conditioner 10 and obtaining a preset frequency threshold; determining whether the compressor frequency is greater than the frequency threshold; if so, controlling the compressor to reduce the frequency to the frequency threshold.

[0075] The preset frequency threshold is equal to the temperature difference threshold value, and the difference between the ambient temperature and the set temperature of the air conditioner 10 corresponds to the optimal frequency of the compressor when only the heat exchanger of the first air outlet column 12 is started. That is to say, if the ambient temperature reaches the above conditions, while the heat exchanger of the second air outlet column 14 is stopped, if the frequency of the compressor is higher than the frequency threshold, then the frequency of the compressor is reduced to the frequency threshold so that the compressor of the air conditioner 10 does not generate excess cooling or heat.

[0076] On this basis, in some optional implementations, the frequency of the compressor can be further reduced as the difference between the ambient temperature and the set temperature of the air conditioner 10 decreases.

[0077] In some optional embodiments, the operating power of the air conditioner 10 can be adjusted more finely when the ambient temperature is stable, so that the ambient temperature can be better and more stably maintained near the set temperature of the air conditioner 10. Specifically, when the ambient temperature is highly close to the set temperature of the air conditioner 10, the frequency of the compressor is adjusted according to the difference between the average temperature of the high-impact area and the set temperature, that is, the greater the difference between the average temperature of the high-impact area and the set temperature, the higher the frequency of the compressor. Through the above embodiment, the air curtain formed by the first air outlet column 12 can better offset the heat or cold in the high-impact area.

[0078] Figure 6 is a schematic block diagram of an air conditioner 10 according to an embodiment of the present invention.

[0079] refer to Figure 6 As shown, the air conditioner 10 includes a first air outlet column 12 and a second air outlet column 14 which are arranged in a transverse interval, and a heat exchanger is respectively arranged in the first air outlet column 12 and the second air outlet column 14.
