[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0052] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] Figure 1This is one of the perspective views of the air conditioner in the air conditioner control method provided by the present invention. Figure 2 This is a front view of the air conditioner in the air conditioner control method provided by the present invention. Figure 3 This is a cross-sectional view of the air conditioner in the air conditioner control method provided by the present invention. Figure 1 , Figure 2 and Figure 3 As shown, an air supply device is used in an air conditioner having a first number of air outlets 204;

[0054] The air supply device includes: a cross-flow fan 401 and a first number of supplementary air fans 201; the supplementary air fans 201 and the air outlets 204 have a one-to-one correspondence; the first number is not less than 2.

[0055] The supplementary air fan 201 can rotate around the inner diameter of the corresponding air outlet 204;

[0056] The supplementary air fan 201 can rotate around the first rotation axis, which is the central axis of the support structure on which the supplementary air fan is installed, and the first rotation axis is perpendicular to the plane where the air outlet 204 of the supplementary air fan 201 is located.

[0057] It should be noted that cross-flow fans have the characteristics of long airflow distance but small airflow range, resulting in a weaker airflow sensation for the user. In this embodiment of the invention, the air supply device in the air conditioner includes a cross-flow fan and multiple rotatable supplementary air fans. Compared to air conditioners using centrifugal fans, cross-flow fans can increase the airflow distance of the air conditioner. At the same time, by utilizing multiple rotatable supplementary air fans, the airflow range of the air conditioner can be increased. Thus, it is possible to increase the airflow range and the airflow distance of the air conditioner without increasing the user's airflow sensation. Here, the airflow distance of the air conditioner can refer to the farthest distance that the cold air, hot air, or natural wind blown out by the air conditioner can reach during operation.

[0058] The surface of the air conditioner housing 203 is provided with a first number of air outlets 204. The first number is not less than 2; in this embodiment of the invention, a value of 2 is used as an example for explanation.

[0059] Each air outlet 204 is provided with an air supply fan 201, which can rotate clockwise or counterclockwise around the inner diameter of the air outlet 204.

[0060] It should be noted that the structures of each air outlet 204 are identical. In this embodiment of the invention, an air outlet 204 and the air supply fan 201 disposed at the air outlet 204 are used as examples to describe the air conditioner and the control method of the air conditioner provided by the present invention. The air outlet 204 and the air supply fan 201 mentioned in the following description can refer to any air outlet 204 in the air conditioner and the air supply fan 201 disposed at the air outlet 204.

[0061] The supplementary air fan 201 can be rotatably connected to the support structure. In this embodiment of the invention, the central axis of the support structure perpendicular to the plane where the air outlet 204 is located can be used as the first axis of rotation, and the horizontal plane where the first axis of rotation is located can be used as the reference horizontal plane. The supplementary air fan 201 can rotate around the first axis of rotation. By controlling the rotation angle of the supplementary air fan 201 around the first axis of rotation, the direction of the air blown out or drawn in by the supplementary air fan 201 can be controlled.

[0062] Optionally, the aforementioned support structure can be a support frame, a support shaft, or a support plate. The embodiments of the present invention do not limit the specific structure of the aforementioned support structure.

[0063] It should be noted that, in this embodiment of the invention, the angle between the central axis of the projection of the supplementary air fan 201 onto the plane where the air outlet 204 is located and the central axis of the air outlet 204 in the vertically upward direction, in the clockwise direction, can be taken as the rotation angle of the supplementary air fan 201 around the first rotation axis. The central axis of the projection of the supplementary air fan 201 onto the plane where the air outlet 204 is located passes through the center point of the air outlet 204.

[0064] Figure 4 This is the second perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. With the air supply fan 201 rotating at an angle of 0° or 360° around the first rotation axis, the perspective view of the air conditioner is as follows. Figure 4 As shown.

[0065] Figure 5 This is the third perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. With the air supply fan 201 rotating at a 90° angle around the first rotation axis, the perspective view of the air conditioner is as follows. Figure 5 As shown.

[0066] Figure 6 This is the fourth perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. With the air supply fan 201 rotating 180° around the first rotation axis, the perspective view of the air conditioner is as follows. Figure 6 As shown.

[0067] Figure 7 This is the fifth perspective view of the air conditioner in the control method of the air conditioner provided by the present invention. With the air supply fan 201 rotating at an angle of 270° around the first rotation axis, the perspective view of the air conditioner is as follows. Figure 7 As shown.

[0068] like Figures 4 to 7As shown, when the rotation angle of the supplementary air fan 201 around the first rotation axis is within [0°, 90°] and within [270°, 360°], the angle between the direction of the gas blown by the supplementary air fan 201 and the vertically upward direction is less than 90°, that is, the supplementary air fan 201 blows gas above the reference horizontal plane; when the rotation angle of the supplementary air fan 201 around the first rotation axis is within (90°, 270°), the angle between the direction of the gas blown by the supplementary air fan 201 and the vertically downward direction is less than 90°, that is, the supplementary air fan 201 blows gas below the reference horizontal plane.

[0069] A transmission device can be provided along the inner diameter of the air outlet 204, and the air supply fan 201 can use the aforementioned transmission device to rotate around the inner diameter of the air outlet 204. The specific structure and connection method of the aforementioned transmission device are not limited in this embodiment of the invention.

[0070] It is understandable that during the rotation of the air supply fan 201 around the inner diameter of the air outlet 204, the first rotation axis and the reference horizontal plane also move up and down with the rotation of the air supply fan 201.

[0071] A cross-flow fan 401 is located below the evaporator 402. The blades of the cross-flow fan 401 can rotate clockwise or counterclockwise.

[0072] Optionally, the air conditioner may also include a movable baffle 206. The movable baffle 206 can be extended when the air conditioner is started to allow air to be drawn into the air conditioner through the air inlet 205. The movable baffle 206 can also be pushed in when the air conditioner is stopped to cover the air inlet 205.

[0073] The movable baffle 206 can be driven by a second stepper motor 208 located near the air inlet 205.

[0074] It should be noted that in this embodiment of the invention, each supplementary air fan 201 can rotate synchronously along the inner diameter of each air outlet 204; each supplementary air fan 201 can also rotate independently along the inner diameter of the air outlet 204 corresponding to each supplementary air fan 201 according to a preset rule. The specific manner in which each supplementary air fan 201 rotates along each air outlet 204 is not limited in this embodiment of the invention.

[0075] It should be noted that in this embodiment of the invention, each air supply fan 201 can rotate synchronously relative to each first rotation axis; each air supply fan 201 can also rotate independently relative to its corresponding first rotation axis according to a preset rule. The specific manner in which each air supply fan 201 rotates relative to each first rotation axis is not limited in this embodiment of the invention.

[0076] In this embodiment of the invention, the air supply device is applied to an air conditioner having a first number of air outlets, including a cross-flow fan and a first number of supplementary air fans. Each air outlet is provided with a supplementary air fan, which can rotate around the inner diameter of the corresponding air outlet. The supplementary air fan can also rotate around a first rotation axis, which is the central axis of the support structure on which the supplementary air fan is installed. Based on the above-mentioned air supply device, the air outlet range and air blowing distance of the air conditioner can be increased without increasing the user's feeling of being blown by the air, thereby improving the user's perception.

[0077] Based on the above embodiments, the air supply device further includes: a first number of first stepper motors 207 and a first number of ring gear mechanisms 301; the first stepper motors 207, the air outlets 204 and the ring gear mechanisms 301 have a one-to-one correspondence.

[0078] The ring gear mechanism 301 is set along the inner diameter of the corresponding air outlet 204. The support structure of the air outlet 204 corresponding to the air supply fan 201 is connected to the ring gear mechanism 301. The first stepper motor 207 is connected to the ring gear mechanism 301 for transmission.

[0079] Optionally, within the housing 203, a ring gear mechanism 301 can be provided along the inner diameter of the air outlet 204. The diameter of the ring gear mechanism 301 is slightly larger than the diameter of the air outlet 204, and the difference between the diameter of the ring gear mechanism 301 and the diameter of the air outlet 204 is less than a preset value. This difference ensures that the diameter of the ring gear mechanism 301 is not excessively large. The preset value can be determined based on prior knowledge, and the specific value of the preset value is not limited in this embodiment of the invention.

[0080] Accordingly, the supplementary air fan 201 can be fixedly connected to any point on the ring gear mechanism 301 through the support structure, and the ring gear mechanism 301 can be driven to rotate by the first stepper motor 207. In turn, the ring gear mechanism 301 can drive the supplementary air fan 201 connected to the support structure to rotate along the inner diameter of the air outlet 204.

[0081] Optionally, when the support structure is a support frame, the bottom of the support frame can be fixedly connected to any point on the ring gear mechanism 301, and the top of the support frame can be equipped with an air supply fan 201; or, when the support structure is a support shaft, one end of the support shaft can be fixedly connected to any point on the ring gear mechanism 301, and the other end of the support shaft can be equipped with an air supply fan 201; or, when the support structure is a support plate, one end of the support plate can be fixedly connected to any point on the ring gear mechanism 301, and the other end of the support plate can be equipped with an air supply fan 201.

[0082] The air supply device in this embodiment of the invention includes a first number of stepper motors and a first number of ring gear mechanisms. The ring gear mechanisms are arranged along the inner diameter of the corresponding air outlet. The support structure of the air supply fan corresponding to the air outlet is connected to the ring gear mechanism. The first stepper motor is driven to the ring gear mechanism. Through the ring gear mechanism and the first stepper motor, the air supply fan is driven to rotate along the inner diameter of the air outlet. The structure is simple and the operation is accurate.

[0083] Based on the above embodiments, the air supply fan 201 includes: a rotary motor, fan blades, and a filter screen;

[0084] The rotary motor is connected to the fan blade drive. The fan blade rotates around the second rotation axis under the drive of the rotary motor. The second rotation axis is the central axis of the air supply fan and is perpendicular to the plane where the air supply fan is located.

[0085] The filter is located on the side of the fan blades closest to the interior space;

[0086] The rotating motor, fan blades, and filter are integrated into a single unit.

[0087] Optionally, the supplemental air fan 201 may include an integrated filter, fan blades, and rotating motor.

[0088] A rotary motor can drive the fan blades to rotate clockwise or counterclockwise around a second rotation axis.

[0089] The filter can be installed on the outside of the fan blades to filter the air blown out or drawn in by the air supply fan 201. The outside of the fan blades refers to the side closest to the indoor space.

[0090] The supplementary air fan in this embodiment of the invention includes an integrated rotary motor, fan blades, and filter screen. It has a simple structure and can filter particulate matter in the air blown out and drawn in by the air conditioner, thereby improving the user experience.

[0091] Based on the above embodiments, the rotation of each supplementary air fan relative to each first rotation axis is synchronous, and the rotation of each supplementary air fan around the inner diameter of each air outlet is synchronous.

[0092] In this embodiment of the invention, each air supply fan rotates synchronously along the inner diameter of each air outlet, and each air supply fan rotates synchronously relative to each first rotation axis. This can avoid the air supply area of ​​the air conditioner being dispersed or concentrated. Without increasing the feeling of air blowing on the human body, it can further increase the air outlet range and the air blowing distance of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve the user's perception.

[0093] It should be noted that the control method for the air conditioner provided by the present invention is applied within a preset time period from the moment the air conditioner is started; the air conditioner includes: multiple air outlets and any of the above-mentioned air supply devices.

[0094] It should be noted that traditional air conditioners, after starting up, can quickly regulate the ambient temperature of a localized area near the unit, but their regulation rate for other areas is slower. Therefore, for a period after a traditional air conditioner starts, significant temperature differences can easily occur between different spaces, resulting in a poor user comfort experience. Thus, how to more flexibly control the air supply system of an air conditioner (including multiple air vents and the aforementioned air delivery mechanism) after startup, to achieve more efficient and balanced regulation of the indoor ambient temperature, is a pressing technical problem that needs to be solved in this field.

[0095] To address this issue and achieve more efficient and balanced control of indoor temperature after the air conditioner is started, this invention provides an air conditioner control method applicable for a preset time period starting from the moment the air conditioner is started. During this preset time period, the air supply device in the air conditioner can be more flexibly controlled based on the control method provided by this invention. This allows for increased airflow distance, improved heat exchange efficiency and capacity, and ultimately, more efficient and balanced control of indoor temperature after the air conditioner is started.

[0096] It should be noted that the aforementioned preset duration can be determined based on prior knowledge; for example, the preset duration can be 10 minutes, 20 minutes, or 30 minutes. The specific value of the preset duration is not limited in this embodiment of the invention.

[0097] Optionally, the air conditioner control method provided by the present invention can also be used within a preset time period from the moment the air conditioner switches its operating mode, thereby increasing the air blowing distance of the air conditioner within the preset time period after the air conditioner switches its operating mode, improving the heat exchange efficiency and heat exchange capacity of the air conditioner, and realizing more efficient and balanced regulation of the indoor ambient temperature after the air conditioner switches its operating mode.

[0098] It should be noted that the specific structure and working process of the air conditioner and the air supply device in the air conditioner in the embodiments of the present invention can be found in the content of the above embodiments and as shown below. Figures 1 to 7 As shown.

[0099] Figure 8 This is a flowchart illustrating the control method for an air conditioner provided by the present invention. The following is a summary of the process. Figure 8 The control method of the air conditioner of the present invention is described. For example... Figure 8 As shown, the method includes: step 801, obtaining the operating mode of the air conditioner;

[0100] It should be noted that the execution subject of this embodiment of the invention is the control device of an air conditioner.

[0101] It should be noted that the air conditioner in this embodiment of the invention can be used to regulate the ambient temperature of an indoor space.

[0102] Typically, users can control the air conditioner to start, operate, or stop according to their needs. User control can be based on input commands. For example, the air conditioner's controller can receive a first control command and, in response, start the compressor for cooling; alternatively, it can receive a second control command and operate in fan mode; or it can receive a third control command and stop the air conditioner.

[0103] It should be noted that user input can take the form of touch input on the target interface, including but not limited to click, swipe, and press input. User input can also be expressed as physical button input or voice input. The target interface can be the user terminal's display interface or the air conditioner's control interface. The physical buttons can be located on the air conditioner itself or on the air conditioner's external controller.

[0104] It is understood that the inputs listed above are merely exemplary examples, meaning that the embodiments of this application include, but are not limited to, the inputs listed above. In actual implementation, user input may include any other possible inputs, which can be specifically determined according to actual usage needs, and the embodiments of this application do not impose any limitations.

[0105] In this embodiment of the invention, when the air conditioner is started, the operating mode of the air conditioner can be obtained in a variety of ways. For example, the operating mode of the air conditioner can be obtained by detecting the control commands received by the air conditioner's controller; or, the operating mode of the air conditioner can be obtained based on the working status of the air conditioner's compressor.

[0106] The operating modes of an air conditioner may include, but are not limited to: cooling mode, heating mode, fan mode, defrost mode, and self-cleaning mode. In cooling mode, the air conditioner blows out cold air to lower the indoor temperature; in heating mode, it blows out hot air to raise the indoor temperature; in fan mode, it blows out natural air to increase indoor air circulation; in defrost mode, it automatically defrosts; and in self-cleaning mode, it performs self-cleaning.

[0107] Step 802: Based on the operating mode of the air conditioner, control the rotation direction of the blades of the cross-flow fan 401 in the air supply device, the rotation direction of the blades of the supplementary air fan 201, and the way the supplementary air fan 201 rotates around the first rotation axis.

[0108] Specifically, after obtaining the operating mode of the air conditioner, condition judgments can be made based on the operating mode of the air conditioner, and the rotation direction of the blades of the cross-flow fan 401 and the air supply fan 201 can be controlled based on the result of the condition judgment.

[0109] It should be noted that when the blades of the cross-flow fan 401 and the air supply fan 201 rotate clockwise, the cross-flow fan 401 and the air supply fan 201 can blow out gas; when the blades of the cross-flow fan 401 and the air supply fan 201 rotate counterclockwise, the cross-flow fan 401 and the air supply fan 201 can draw in gas.

[0110] After obtaining the operating mode of the air conditioner, the rotation of the air supply fan 201 around the first rotation axis can be controlled based on the results of the above condition judgment.

[0111] In this embodiment of the invention, within a preset time period starting from the moment the air conditioner is started, the rotation direction of the fan blades of the air supply fan and the cross-flow fan in the air supply device, as well as the manner in which the air supply fan rotates around the first rotation axis, are controlled based on the operating mode of the air conditioner. This allows for more flexible control of the air supply device within the preset time period after the air conditioner is started, thereby improving the heat exchange efficiency and capacity of the air conditioner. Consequently, it enables more efficient and balanced regulation of the indoor ambient temperature within a short period after the air conditioner is started, thus enhancing the user's perception.

[0112] Based on the above embodiments, and based on the operating mode of the air conditioner, the method of controlling the rotation direction of the blades of the cross-flow fan 401, the rotation direction of the blades of the supplementary air fan 201, and the rotation of the supplementary air fan 201 around the first rotation axis in the air supply device includes: when the operating mode of the air conditioner is cooling mode, controlling the blades of the cross-flow fan 401 to rotate clockwise, controlling the blades of the supplementary air fan 201 to rotate clockwise, and controlling the supplementary air fan 201 to rotate circumferentially around the first rotation axis.

[0113] Specifically, within a preset time period from the moment the air conditioner is started, if the air conditioner is in cooling mode, the blades of the cross-flow fan 401 can be controlled to rotate clockwise, the blades of the air supply fan 201 can be controlled to rotate clockwise, and the air supply fan 201 can be controlled to rotate 360° around the first rotation axis, thereby enabling the air supply fan 201 to rotate 360° to deliver air, improving the heat exchange efficiency and heat exchange capacity of the air conditioner in cooling mode.

[0114] It is understandable that when the air supply fan 201 rotates 360° around the first rotation axis, the rotation angle of the air supply fan 201 around the first rotation axis is between 0°-90°-180°-270°-360° (0°).

[0115] This invention, by controlling the air supply fan to rotate 360° to deliver air when the air conditioner is in cooling mode, allows for more flexible control over the rotation direction of the cross-flow fan and the air supply fan, as well as the way the air supply fan rotates around the first rotation axis. This improves the heat exchange efficiency and capacity of the air conditioner in cooling mode, thereby enabling a more balanced reduction of the indoor ambient temperature in a short period of time after the air conditioner is started.

[0116] Based on the above embodiments, and based on the operating mode of the air conditioner, the method of controlling the rotation direction of the blades of the cross-flow fan 401, the rotation direction of the blades of the supplementary air fan 201, and the rotation of the supplementary air fan 201 around the first rotation axis in the air supply device includes: when the operating mode of the air conditioner is heating mode, controlling the blades of the cross-flow fan 401 to rotate clockwise, controlling the blades of the supplementary air fan 201 to rotate clockwise, and controlling the supplementary air fan 201 to rotate circumferentially around the first rotation axis.

[0117] Specifically, within a preset time period from the moment the air conditioner is started, if the air conditioner is in heating mode, the blades of the cross-flow fan 401 can be controlled to rotate clockwise, the blades of the air supply fan 201 can be controlled to rotate clockwise, and the air supply fan 201 can be controlled to rotate 360° around the first rotation axis, thereby enabling the air supply fan 201 to rotate 360° to deliver air, improving the heat exchange efficiency and heat exchange capacity of the air conditioner in heating mode.

[0118] This invention, by controlling the air supply fan to rotate 360° to deliver air when the air conditioner is in heating mode, allows for more flexible control over the rotation direction of the cross-flow fan and the air supply fan, as well as the way the air supply fan rotates around the first rotation axis. This improves the heat exchange efficiency and capacity of the air conditioner in heating mode, thereby enabling a more balanced increase in indoor ambient temperature in a short period of time after the air conditioner is started.

[0119] Based on the above embodiments, and based on the operating mode of the air conditioner, the method of controlling the rotation direction of the blades of the cross-flow fan 401, the rotation direction of the blades of the supplementary air fan 201, and the rotation of the supplementary air fan 201 around the first rotation axis in the air supply device includes: when the operating mode of the air conditioner is the air supply mode, controlling the blades of the cross-flow fan 401 to rotate clockwise, controlling the blades of the supplementary air fan 201 to rotate clockwise, and controlling the supplementary air fan 201 to reciprocate around the first rotation axis below the reference horizontal plane.

[0120] The reference horizontal plane is the horizontal plane where the first axis of rotation is located.

[0121] Specifically, within a preset time period from the moment the air conditioner is started, if the air conditioner is in the air supply mode, the blades of the cross-flow fan 401 can be controlled to rotate clockwise, the blades of the supplementary air fan 201 can be controlled to rotate clockwise, and the supplementary air fan 201 can be controlled to reciprocate around the first rotation axis below the reference horizontal plane, so that the supplementary air fan 201 can swing and supply air downwards to the reference horizontal plane, thereby improving the air supply effect of the air conditioner.

[0122] It is understandable that when the air supply fan 201 reciprocates around the first rotation axis below the reference horizontal plane, the rotation angle of the air supply fan 201 around the first rotation axis varies between 90°-180°-270°.

[0123] This invention, by controlling the air supply fan to swing downwards towards the reference horizontal plane when the air conditioner is in the air supply mode, can more flexibly control the rotation direction of the air supply fan blades and the way they rotate around the first rotation axis, thereby improving the air supply effect of the air conditioner in the air supply mode and enabling a more balanced regulation of the indoor ambient temperature in a short period of time after the air conditioner is turned on.

[0124] Based on the above embodiments, and based on the operating mode of the air conditioner, the method of controlling the rotation direction of the blades of the cross-flow fan 401, the rotation direction of the blades of the supplementary air fan 201, and the rotation of the supplementary air fan 201 around the first rotation axis in the air supply device includes: when the operating mode of the air conditioner is the target mode, controlling the blades of the cross-flow fan 401 to rotate counterclockwise, controlling the blades of the supplementary air fan 201 to rotate counterclockwise, and controlling the supplementary air fan 201 to rotate around the first rotation axis to above the reference horizontal plane.

[0125] Specifically, within a preset time period from the moment the air conditioner is started, if the air conditioner is in defrost mode or self-cleaning mode, the blades of the cross-flow fan 401 can be controlled to rotate counterclockwise, and the blades of the air supply fan 201 can be controlled to rotate counterclockwise, so that the air supply fan 201 can rotate above the reference horizontal plane. This allows the air supply fan 201 to swing and draw in air from above the reference horizontal plane, thereby avoiding affecting the air conditioner's performance in the target mode and reducing the noise of the air conditioner.

[0126] It is understandable that when the supplementary air fan 201 rotates around the first rotation axis to above the reference horizontal plane, the rotation angle of the supplementary air fan 201 around the first rotation axis is within (0°, 90°) and within (270°, 360°).

[0127] In this embodiment of the invention, when the air conditioner is in the target operating mode, the air supply fan is controlled to swing and draw in air from above the reference horizontal plane, which can avoid affecting the performance of the air conditioner in the target mode and reduce the noise of the air conditioner.

[0128] Based on the content of the above embodiments, the preset duration ranges from 10 minutes to 30 minutes.

[0129] Specifically, based on prior knowledge, the preset duration can be set between 10 and 30 minutes. For example, the preset duration can be 10 minutes, 20 minutes, or 30 minutes.

[0130] Preferably, the preset duration can be 20 minutes.

[0131] Accordingly, the present invention provides a control method for an air conditioner, which allows for more flexible control of the aforementioned air supply device within 10, 20, or 30 minutes from the moment the air conditioner is started.

[0132] In this embodiment of the invention, the preset duration is determined to be between 10 and 30 minutes based on prior knowledge. This allows for more balanced control of the indoor ambient temperature within a short period after the air conditioner is turned on, while also saving energy consumption.

This allows for more flexible control of the air supply device within the preset time period after the air conditioner is started, thereby improving the heat exchange efficiency and heat exchange capacity of the air conditioner. As a result, it enables more efficient and balanced regulation of the indoor ambient temperature in a short period of time after the air conditioner is started, thus improving the user's perception.
