A first fan 31 is provided corresponding to the left air vent 11 to adjust the air volume out of the left air vent 11 by adjusting the speed of the first fan 31. A second fan 32 is provided corresponding to the right air vent 12 to adjust the air volume out of the right air vent 12 by adjusting the speed of the second fan 32. A first heat exchange unit is provided corresponding to the left air vent 11 to adjust the coolness of the air out of the left air vent 11 by adjusting the refrigerant flow rate of the first heat exchange unit. A second heat exchange unit is provided corresponding to the right air vent 12 to adjust the coolness of the air out of the right air vent 12 by adjusting the refrigerant flow rate of the second heat exchange unit.

[0095] In one embodiment, the air conditioner indoor unit further includes a first valve body 41 disposed on the first heat exchange unit. The opening of the first valve body 41 is adjustable to regulate the refrigerant flow rate in the first heat exchange unit. The first valve body 41 is connected to a control unit, which is configured to control the opening of the first valve body 41 based on the position of a person detected by the human position detector 10. With this structural arrangement, the opening adjustment mechanism of the first valve body 41 intelligently adjusts the refrigerant flow rate in the first heat exchange unit based on the person's position information detected by the human position detector 10. This means that when a person is located in the left side of the room (associated with the first fan 31 and the first heat exchange unit), the system can increase the refrigerant flow rate in that area to improve cooling efficiency and ensure a rapid temperature drop in the area where the person is located. By controlling the opening of the first valve body 41, the refrigerant flow rate can be reduced in unoccupied areas of the room, avoiding unnecessary cooling and thus reducing overall energy consumption.

[0096] In one embodiment, the air conditioner indoor unit further includes a second valve body 42, which is disposed on the second heat exchange portion. The opening of the second valve body 42 is adjustable to adjust the refrigerant flow in the second heat exchange portion. The second valve body 42 is connected to a control component, which is configured to control the opening of the second valve body 42 based on the position of a person detected by the human position detector 10. This structural arrangement, in which the second valve body 42 is connected to the control component, ensures that when human activity is primarily in the right side of the room, the refrigerant flow to the right side is increased, improving cooling efficiency and meeting the user's temperature requirements in that area. When the right side of the room is unoccupied, the opening of the second valve body 42 is reduced by the control component, further reducing energy consumption while maintaining the overall cooling effect.

[0097] In one embodiment, the air conditioner indoor unit further includes a first valve body 41 and a second valve body 42. The first valve body 41 is disposed on the first heat exchange section, and the opening of the first valve body 41 is adjustable to adjust the refrigerant flow rate in the first heat exchange section. The first valve body 41 is connected to a control component, which is configured to control the opening of the first valve body 41 based on the human position detected by the human position detector 10. The second valve body 42 is disposed on the second heat exchange section, and the opening of the second valve body 42 is adjustable to adjust the refrigerant flow rate in the second heat exchange section. The second valve body 42 is connected to a control component, which is configured to control the opening of the second valve body 42 based on the human position detected by the human position detector 10. With this structural arrangement, the opening adjustment mechanism of the first valve body 41 can intelligently adjust the refrigerant flow rate in the first heat exchange section based on the human position information detected by the human position detector 10. This means that when a human body is located in the left area of the room (related to the first fan 31 and the first heat exchange unit), the system can increase the refrigerant flow on the left side to improve the cooling efficiency of this area and ensure that the temperature in the area where the human body is located drops rapidly. By controlling the opening of the first valve body 41, the refrigerant flow can be reduced in the area of the room where no one is active, avoiding unnecessary cooling, thereby reducing overall energy consumption. The second valve body 42 is connected to the control component to ensure that when human activities are mainly in the right area of the room, the refrigerant flow on the right side can be increased, the cooling efficiency can be improved, and the temperature requirements of the user in this area can be met. When there is no one in the right area of the room, reducing the opening of the second valve body 42 through the control component can further reduce energy consumption while maintaining the overall cooling effect.

[0098] In one embodiment, the air conditioner indoor unit further includes a left air guide 51 rotatably disposed at the left air outlet 11 to adjust the flow cross-section of the left air outlet 11 for conditioned air to flow out. The left air guide 51 is connected to a control unit that controls the rotation angle of the left air guide 51 based on the detection results of the human position detector 10. With this structural arrangement, the rotation angle of the left air guide 51 can be intelligently adjusted by the control unit, ensuring that the cold air is precisely directed to the left side of the area where people are active based on the detection results of the human position detector 10. This not only improves cooling efficiency, ensuring that the cold air reaches the area requiring cooling directly, but also enhances user comfort by avoiding the discomfort of being blown directly by the cold air. By adjusting the rotation angle of the left air guide 51, the flow direction and cross-section of the cold air can be effectively controlled, reducing cooling waste in unoccupied areas and thereby reducing the overall energy consumption of the air conditioning system.

[0099] In one embodiment, the air-conditioning indoor unit further includes a right air guide portion 52, which is rotatably disposed at the right air outlet 12 to adjust the flow cross-section of the right air outlet 12 for allowing the conditioned air to flow out; the right air guide portion 52 is connected to a control component, which is used to control the rotation angle of the right air guide portion 52 according to the detection result of the human body position detection component 10. With such a structural setting, the right air guide portion 52 can achieve targeted air supply to the right area by intelligently adjusting its rotation angle. When human activities are mainly concentrated on the right side of the room, the control component can accurately adjust the right air guide portion 52 based on the information of the human body position detection component 10, so that the cold air can more effectively cover the area where the user is located. The intelligent control of the right air guide portion 52 allows the system to adjust the flow cross-section of the cold air according to the actual needs of the right area, thereby reducing the distribution of cold air in the unmanned area and achieving more refined energy consumption management.

[0100] In one embodiment, the air conditioner indoor unit further includes a left air guide 51 and a right air guide 52. The left air guide 51 is rotatably disposed at the left air outlet 11 to adjust the flow cross-section of the left air outlet 11 for conditioned air to flow out. The left air guide 51 is connected to a control unit that controls the rotation angle of the left air guide 51 based on the detection results of the human position detector 10. The right air guide 52 is rotatably disposed at the right air outlet 12 to adjust the flow cross-section of the right air outlet 12 for conditioned air to flow out. The right air guide 52 is connected to a control unit that controls the rotation angle of the right air guide 52 based on the detection results of the human position detector 10. With this structural arrangement, the rotation angle of the left air guide 51 can be intelligently adjusted by the control unit based on the detection results of the human position detector 10, ensuring that cool air is precisely directed to the left side of the area where people are active. This not only improves cooling efficiency, ensuring that cool air reaches the area requiring cooling, but also enhances user comfort by avoiding the discomfort of being directly blown by cold air. By adjusting the rotation angle of the left air guide 51, the flow direction of the cold air and the size of the circulation cross-section can be effectively controlled, reducing the waste of cold air in unmanned areas, thereby reducing the overall energy consumption of the air-conditioning system. The right air guide 52 can achieve targeted air supply to the right area by intelligently adjusting its rotation angle. When human activities are mainly concentrated on the right side of the room, the control unit can accurately adjust the right air guide 52 based on the information of the human position detection unit 10, so that the cold air can more effectively cover the area where the user is located. The intelligent control of the right air guide 52 allows the system to adjust the circulation cross-section of the cold air according to the actual needs of the right area, thereby reducing the distribution of cold air in unmanned areas and achieving more refined energy consumption management.

[0101] Specifically, the left air guide portion 51 includes a plurality of left air guide plates spaced apart from each other, with a left circulation channel for the conditioned air to flow out formed between two adjacent left air guide plates. The right air guide portion 52 includes a plurality of right air guide plates spaced apart from each other, with a right circulation channel for the conditioned air to flow out formed between two adjacent right air guide plates.

[0102] Specifically, the left air outlet 11 extends along a first predetermined direction. The left air guide 51 has a first air guiding position, a second air guiding position, and a third air guiding position. When the left air guide 51 is in the first air guiding position, the extension direction of the left air guide 51 is parallel to the first predetermined direction. When the left air guide 51 is in the second air guiding position, the extension direction of the left air guide 51 is arranged at a first predetermined angle to the first predetermined direction. When the left air guide 51 is in the third air guiding position, the extension direction of the left air guide 51 is arranged at a second predetermined angle to the first predetermined direction. The first predetermined angle is greater than or equal to 10° and less than or equal to 15°; the second predetermined angle is greater than or equal to 30° and less than or equal to 45°. In this way, the left air guide 51 can precisely control the direction of the cold air by being positioned parallel to the first predetermined direction (the first air guiding position), at a first predetermined angle of 10° to 15° to the first predetermined direction (the second air guiding position), and at a second predetermined angle of 30° to 45° to the first predetermined direction (the third air guiding position). This multi-level wind guide angle adjustment ensures that the cold air can be more effectively delivered to the left area according to the position of human activities, thereby improving the cooling efficiency.

[0103] Specifically, the right air vent 12 extends along a second preset direction; the right air guide portion 52 has a fourth air guide position, a fifth air guide position, and a sixth air guide position; when the right air guide portion 52 is in the fourth air guide position, the extension direction of the right air guide portion 52 is parallel to the second preset direction; when the right air guide portion 52 is in the fifth air guide position, the extension direction of the right air guide portion 52 is set at a third preset angle to the second preset direction; when the right air guide portion 52 is in the sixth air guide position, the extension direction of the right air guide portion 52 is set at a fourth preset angle to the second preset direction. The third preset angle is greater than or equal to 10° and less than or equal to 15°; and the fourth preset angle is greater than or equal to 30° and less than or equal to 45°. In this way, the right air guide portion 52, through the fourth, fifth, and sixth air guide positions, can accurately guide cold air to the right side of the human body's active area, thereby improving cooling efficiency and comfort. By adjusting the angle of the right air guide 52, the direction of cold air delivery can be dynamically adjusted according to the changes in the position of human activities, providing a more personalized and comfortable cooling experience.

[0104] In one embodiment, the air conditioner indoor unit also includes an indoor temperature detection component, the detection end of the indoor temperature detection component is arranged on the indoor unit body 1, the indoor temperature detection component is used to detect the indoor temperature, the indoor temperature detection component is connected to the control component, and the control component is used to control whether the human body position detection component 10 performs detection according to the detection result of the indoor temperature detection component. With such a structural arrangement, intelligent control based on the indoor temperature can be achieved through the coordinated work of the indoor temperature detection component and the control component. When the indoor temperature has dropped to within the set comfortable temperature range, the control component can automatically stop the operation of the human body position detection component 10, thereby avoiding unnecessary position detection when the temperature is already suitable and saving energy consumption. When the indoor temperature has met the requirements, the control component will stop the operation of the human body position detection component 10, which not only saves energy, but also reduces unnecessary work of the human body position detection component 10, thereby reducing hardware wear and maintenance costs.

[0105] In one embodiment, the indoor unit body 1 is mounted on a foundation, and the human position detector 10 is positioned on a side of the indoor unit body 1 away from the foundation, between the left and right air vents 11, 12. This structural arrangement, in which the human position detector 10 is positioned on a side of the indoor unit body 1 away from the foundation, between the left and right air vents 11, 12, ensures that the sensor has an optimal detection field of view and angle, thereby more accurately and comprehensively identifying the movement of people within the room. This layout design overcomes the potential blind spots or errors that may be caused by improper positioning of the traditional human position detector 10, thereby improving the accuracy of human position detection.

[0106] In one embodiment, the human position detector 10 is a millimeter-wave radar structure. Millimeter-wave radar structures operate by transmitting and detecting electromagnetic waves. When electromagnetic waves encounter an obstacle, they are reflected. If these reflected waves are received again at their origin, it indicates that the obstacle is in the direction of propagation. For example, the millimeter-wave radar transmits electromagnetic waves in all directions within a 120° radius forward of the air conditioner's origin. If a reflected wave is received in area S1, it indicates that someone is present in area S1. The distance between the person and the air conditioner is also calculated based on the time between transmission and reception.

[0107] like Figure 4 As shown, one embodiment of the present invention provides an air-conditioning system, which includes the above-mentioned air-conditioning indoor unit, condenser 6, outdoor fan 7 and compressor 8. The air-conditioning indoor unit, condenser 6 and compressor 8 are connected in sequence, and the outdoor fan 7 is arranged on one side of the condenser 6.

[0108] The air conditioning system provided by one embodiment of the present invention, by subdividing the evaporator 2 into a first heat exchange section and a second heat exchange section, which are respectively connected to the first fan 31 and the second fan 32, can dynamically adjust the refrigerant flow rate and fan speed on both sides of the air conditioner indoor unit according to the human activity position. This structure and control method can more accurately deliver cooling energy to the human activity area, improving cooling efficiency, and effectively increasing the cooling capacity of the air conditioner in high-temperature environments. By monitoring the range of human activity in the room through the human position detection element 10, the refrigerant flow rate and fan speed in inactive areas can be intelligently adjusted, avoiding the waste of cooling energy in unnecessary areas and thus reducing the energy consumption of the air conditioner. The linkage between the human position detection element 10 and the control element enables intelligent control of the air conditioner indoor unit, automatically adapting to changes in human activity in the room, avoiding ineffective air delivery to areas without human activity, and further improving the cooling efficiency of the air conditioner by making the air delivery of the air conditioner indoor unit more adaptable to the distribution of human activity in the room. Therefore, the air conditioning system provided by this embodiment can solve the problem of low cooling efficiency of air conditioning systems in high-temperature environments in the prior art.

[0109] Specifically, the condenser 6 , the compressor 8 and the air conditioner indoor unit are connected via a four-way valve 9 .

[0110] like Figure 5 and Figure 6 As shown, one embodiment of the present invention provides a control method, which is applicable to the above-mentioned air-conditioning system, and the control method includes: dividing the room where the air-conditioning indoor unit is located into multiple activity areas along the direction from the left air outlet 11 of the air-conditioning indoor unit to the right air outlet 12 of the air-conditioning indoor unit of the air-conditioning system; obtaining the activity area where the human body is located to obtain the human body active area; adjusting the refrigerant flow of the first heat exchange part of the air-conditioning indoor unit and the second heat exchange part of the air-conditioning indoor unit and / or the speed of the first fan 31 of the air-conditioning indoor unit and the second fan 32 of the air-conditioning indoor unit according to the human body active area.

[0111] By using the control method provided in one embodiment of the present invention, a room is divided into multiple activity zones. The refrigerant flow rate and fan speed are adjusted based on the human activity zones. This ensures that the cooling capacity of the air conditioning system is precisely delivered to areas near the human body, avoiding waste of cooling capacity in unoccupied areas, thereby improving cooling efficiency. This intelligent control can significantly enhance the cooling performance of the air conditioner, particularly in high-temperature environments. By dynamically adjusting the refrigerant flow rates of the first and second heat exchange units, as well as the speeds of the first and second fans 31 and 32, based on the actual human activity zones, the air conditioning system avoids overcooling in inactive areas, achieving more efficient energy utilization and reducing energy consumption during air conditioning operation. Furthermore, as the human activity zones change, the air conditioner indoor unit can quickly respond, adjusting the refrigerant flow rate and fan speed, ensuring that the air conditioning system can always adapt to immediate environmental changes and provide optimal cooling performance. Therefore, the control method provided in this embodiment can address the problem of low cooling efficiency of air conditioning systems in high-temperature environments in the prior art.

[0112] Specifically, the active area includes a first area, a second area, a third area, a fourth area, and a fifth area arranged in sequence from the left air outlet 11 to the right air outlet 12; when the human body is located in the first area and the second area, the human body active area is the first active area; when the human body is located in the second area and the third area, the human body active area is the second active area; when the human body is located in the third area and the fourth area, the human body active area is the third active area; when the human body is located in the fourth area and the fifth area, the human body active area is the fourth active area; when the human body is located in various areas, the human body active area is the fifth active area. The method for adjusting the refrigerant flow of the first heat exchange unit and the second heat exchange unit according to the human body active area includes: when the human body active area is the first active area, making the refrigerant flow of the first heat exchange unit greater than the refrigerant flow of the second heat exchange unit; when the human body active area is the second active area, the third active area, or the fifth active area, making the refrigerant flow of the first heat exchange unit equal to the refrigerant flow of the second heat exchange unit; and when the human body active area is the fourth active area, making the refrigerant flow of the first heat exchange unit less than the refrigerant flow of the second heat exchange unit. In this way, when the human activity zone is the first active zone (with the person on the left), the system increases the refrigerant flow rate in the first heat exchanger to achieve efficient cooling of the left area, meeting the user's cooling needs on the left side. When the human activity zone is the second, third, or fifth active zone (with the person in the center or dispersed), the refrigerant flow rate is evenly distributed between the first and second heat exchangers, ensuring uniform temperature distribution throughout the room and avoiding localized overcooling or overheating. When the human activity zone is the fourth active zone (with the person on the right), the system increases the refrigerant flow rate in the second heat exchanger to enhance the cooling effect on the right side, meeting the user's cooling needs on the right side. Because the refrigerant flow rate is adjusted based on the human activity zone, this intelligent control method can significantly reduce refrigerant waste in unoccupied areas, lowering energy consumption and achieving energy conservation and emission reduction goals. The effect is particularly significant in high-temperature environments.

[0113] Specifically, the activity area includes a first area, a second area, a third area, a fourth area, and a fifth area, which are sequentially arranged along the direction from the left air outlet 11 to the right air outlet 12. When a human body is located within the first and second areas, the human body active area is the first active area; when a human body is located within the second and third areas, the human body active area is the second active area; when a human body is located within the third and fourth areas, the human body active area is the third active area; when a human body is located within the fourth and fifth areas, the human body active area is the fourth active area; and when a human body is located in various areas, the human body active area is the fifth active area. The method for adjusting the rotational speeds of the first fan 31 and the second fan 32 according to the human body active area includes: when the human body active area is the first active area, making the rotational speed of the first fan 31 greater than the rotational speed of the second fan 32; when the human body active area is the second, third, or fifth active area, making the rotational speed of the first fan 31 equal to the rotational speed of the second fan 32; and when the human body active area is the fourth active area, making the rotational speed of the first fan 31 less than the rotational speed of the second fan 32. In this way, if the user primarily moves in the first active zone (left side), the first fan 31 will operate at a higher speed, thereby increasing the delivery of cool air and creating a cooler environment for the user. When the human activity zone is centrally located or dispersed (second, third, or fifth active zones), the first fan 31 and second fan 32 will maintain the same speed, avoiding energy waste caused by excessive airflow while ensuring uniform indoor temperature distribution. When the human activity zone shifts to the right side of the room (fourth active zone), the speed of the second fan 32 will be higher than that of the first fan 31 to adapt to the user's changed position and ensure effective coverage of the cool air. This demonstrates the high flexibility of the air conditioning control method in regulating indoor temperature. Dynamically adjusting the fan speed as the human activity zone changes can avoid excessive airflow in inactive zones, thereby reducing the energy consumption of the air conditioning system during peak hours, helping to smoothly navigate high temperatures and reduce peak energy consumption.

[0114] Specifically, if Figure 6As shown, the active area is the area on one side of the air conditioner indoor unit, and the preset axis A is perpendicular to the outer wall of the air conditioner indoor unit and is located in the middle of the left air outlet 11 and the right air outlet 12. The first area S1 is a fan-shaped area, and the angle between the left edge of the first area S1 and the preset axis A is α1, 30°≤α1≤60°, and the right edge of the first area S1 coincides with the left edge of the second area S2. The second area S2 is a fan-shaped area, and the angle between the left edge of the second area S2 and the preset axis A is α2, 10°≤α2≤35°, and the right edge of the second area S2 coincides with the left edge of the third area S3. The third area S3 is a fan-shaped or strip-shaped area. When the third area S3 is a fan-shaped area, the third area S3 The angle between the left edge of the third area S3 and the preset axis A is α3, 0°<α3≤10°, the angle between the right edge of the third area S3 and the preset axis A is equal to α3, the right edge of the third area S3 coincides with the left edge of the fourth area S4, the fourth area S4 is a fan-shaped area, the angle between the right edge of the fourth area S4 and the preset axis A is equal to α2, the right edge of the fourth area S4 coincides with the left edge of the fifth area S5, the fifth area S5 is a fan-shaped area, and the angle between the right edge of the fifth area S5 and the preset axis A is equal to α1.

[0115] Specifically, a human body active area being the first active area means that the activity trajectory of the human body position is within the first area S1 and the second area S2; a human body active area being the second active area means that the activity trajectory of the human body position is within the second area S2 and the third area S3; a human body active area being the third active area means that the activity trajectory of the human body position is within the third area S3 and the fourth area S4; a human body active area being the fourth active area means that the activity trajectory of the human body position is within the fourth area S4 and the fifth area S5; a human body active area being the fifth active area means that the activity trajectory of the human body position is within the first area S1, the second area S2, the third area S3, the fourth area S4 and the fifth area S5, and is distributed relatively dispersedly and not concentrated within a certain area.

[0116] In one embodiment, before adjusting the refrigerant flow rates of the first and second heat exchange units and / or the rotational speeds of the first and second fans 31 and 32 based on the human activity zones, the control method further includes: obtaining the outdoor ambient temperature; and determining the refrigerant flow rates of the first and second heat exchange units and / or the rotational speeds of the first and second fans 31 and 32 corresponding to the different human activity zones based on the outdoor ambient temperature. By pre-acquiring the outdoor ambient temperature and determining the refrigerant flow rates of the first and second heat exchange units, as well as the rotational speeds of the first and second fans 31 and 32 corresponding to the human activity zones based on the specific temperature values, this solution can more accurately respond to high-temperature environments, ensuring that the air conditioning system provides cooling that meets human comfort requirements under varying outdoor temperatures, thereby improving the system's adaptability and efficiency in extreme weather conditions. By intelligently adjusting the cooling intensity of the human activity zones based on varying outdoor temperatures, users can enjoy a more personalized, comfortable, and efficient cooling experience.

[0117] Specifically, when the outdoor ambient temperature is greater than the first preset temperature and less than or equal to the second preset temperature, the outdoor ambient temperature is in the first temperature zone; when the outdoor ambient temperature is greater than the second preset temperature and less than or equal to the third preset temperature, the outdoor ambient temperature is in the second temperature zone; when the outdoor ambient temperature is greater than the third preset temperature, the outdoor ambient temperature is in the third temperature zone; wherein: the method for determining the refrigerant flow rate of the first heat exchange part and the second heat exchange part corresponding to different human activity areas according to the size of the outdoor ambient temperature includes: when the human activity area is the first active area, making Q 11 =Q 21 =Q 31 , Q 12 >Q 22 >Q 32 When the human body active area is the second active area, the third active area or the fifth active area, Q 11 >Q 21 =Q 31 , Q 12 >Q 22 =Q 32 ; When the human body active area is the fourth active area, make Q 12 =Q 22 =Q 32 , Q 11 >Q 21 >Q 31 .Q 11 is the refrigerant flow rate of the first heat exchange part corresponding to the first temperature zone, Q 21 is the refrigerant flow rate of the first heat exchange part corresponding to the second temperature zone, Q 31 is the refrigerant flow rate of the first heat exchange part corresponding to the third temperature zone, Q 12is the refrigerant flow rate of the second heat exchange part corresponding to the first temperature zone, Q 22 is the refrigerant flow rate of the second heat exchange part corresponding to the second temperature zone, Q 32 is the refrigerant flow rate of the second heat exchange unit corresponding to the third temperature zone. This setup divides the outdoor ambient temperature into the first, second, and third temperature zones, and adjusts the refrigerant flow rates of the first and second heat exchange units in each temperature zone based on the human body's active areas. This ensures that the air conditioning system can provide the cooling capacity that best suits human needs at different outdoor temperatures. In the lower temperature zone (the first temperature zone), the refrigerant flow rate near the human body's active areas is relatively small, while in the higher temperature zones (the second and third temperature zones), the refrigerant flow rate gradually increases as the temperature rises. This differentiated control strategy can effectively reduce the air conditioner's energy consumption when the outdoor temperature is suitable, achieving intelligent energy-saving effects, especially in hot seasons, by avoiding unnecessary energy waste.

[0118] Specifically, when the outdoor ambient temperature is greater than the first preset temperature and less than or equal to the second preset temperature, the outdoor ambient temperature is in the first temperature zone; when the outdoor ambient temperature is greater than the second preset temperature and less than or equal to the third preset temperature, the outdoor ambient temperature is in the second temperature zone; when the outdoor ambient temperature is greater than the third preset temperature, the outdoor ambient temperature is in the third temperature zone; wherein: the method for determining the rotational speeds of the first fan 31 and the second fan 32 corresponding to different human activity zones according to the size of the outdoor ambient temperature includes: when the human activity zone is the first active zone, making R 11 =R 21 =R 31 、R 12 =R 22 >R 32 When the human body active area is the second active area, the third active area or the fifth active area, R 11 =R 21 >R 31 、R 12 =R 22 >R 32 ; When the human body active area is the fourth active area, make R 12 =R 22 =R 32 、R 11 =R 21 >R 31 . R 11 is the speed of the first fan 31 corresponding to the first temperature zone, R 21 is the speed of the first fan 31 corresponding to the second temperature zone, R 31 is the speed of the first fan 31 corresponding to the third temperature zone, R 12 is the speed of the second fan 32 corresponding to the first temperature zone, R 22 is the speed of the second fan 32 corresponding to the second temperature zone, R32 is the speed of second fan 32 corresponding to the third temperature zone. With this configuration, through graded control of the outdoor ambient temperature (first, second, and third temperature zones), the embodiment of the present invention dynamically adjusts the speeds of first and second fans 31, 32, ensuring that fan speeds match human activity areas in different temperature zones, improving cooling efficiency and energy conversion. Intelligent analysis and regulation of outdoor ambient temperature enables the air conditioning system to better adapt to fluctuations in the external environment. This dynamic adjustment mechanism ensures efficient, stable, and comfortable operation, particularly in high summer temperatures.

[0119] Specifically, the first preset temperature is 40°C, the second preset temperature is 45°C, and the third preset temperature is 55°C.

[0120] Specifically, the method for determining the refrigerant flow of the first heat exchange part and the second heat exchange part corresponding to different human activity areas according to the size of the outdoor ambient temperature includes: when the human activity area is the first active area, Q 11 =Q 21 =Q 31 =Q 01 , Q 12 =1 / 3Q 02 , Q 22 =1 / 4Q 02 , Q 32 =0; when the human body active area is the second active area, the third active area or the fifth active area, Q 11 =1 / 2Q 01 , Q 12 =1 / 2Q 02 , Q 21 =Q 31 =1 / 3Q 01 , Q 22 =Q 32 =1 / 3Q 02 ; When the human body active area is the fourth active area, Q 12 =Q 22 =Q 32 =Q 02 , Q 11 =1 / 3Q 01 , Q 21 =1 / 4Q 01 , Q 31 =0; where Q 01 is the refrigerant flow rate of the first heat exchange part corresponding to the rated cooling capacity of the air-conditioning system, Q 02The refrigerant flow rate of the second heat exchanger corresponds to the rated cooling capacity of the air conditioning system. With this configuration, in the first active zone (left side, where people are active), the system maintains the refrigerant flow rate of the first heat exchanger at the rated value, while significantly reducing or shutting off the refrigerant flow rate of the second heat exchanger. This ensures that cooling air is concentrated in the active areas, maximizing cooling efficiency. In the second, third, and fifth active zones, the refrigerant flow rates of the first and second heat exchangers are evenly distributed. This ensures coverage of a wide range of active zones while avoiding excessive energy consumption, demonstrating efficient energy utilization and energy-saving operation. In the fourth active zone (right side, where people are active), the refrigerant flow rate of the second heat exchanger is set to the rated value, while the refrigerant flow rate of the first heat exchanger is significantly reduced or even shut off. This targeted refrigerant flow adjustment provides a personalized cooling experience based on the changing activity zones, ensuring that cooling air is precisely delivered to the user's location and enhancing comfort. This refined management of refrigerant flow avoids overcooling in inactive zones, thereby reducing the overall load on the air conditioning system, minimizing the risk of equipment overload caused by high temperatures, extending system life, and reducing maintenance costs.

[0121] Specifically, the method for determining the rotation speeds of the first fan 31 and the second fan 32 corresponding to different human activity zones according to the size of the outdoor ambient temperature includes: when the human activity zone is the first activity zone, R 11 =R 21 =R 31 =R 011 , R 12 =R 22 =R 023 , R 32 =0; when the human body active area is the second active area, the third active area or the fifth active area, R 11 =R 21 =R 012 , R 31 =R 013 , R 12 =R 22 =R 022 , R 32 =R 023 ; When the human body active area is the fourth active area, R 12 =R 22 =R 32 =R 021 , R 11 =R 21 =R 011 , R 31 =0; wherein the first fan 31 has a first high wind speed, a first medium wind speed and a first low wind speed with decreasing speeds, R 011 is the speed corresponding to the first high wind speed, R 012is the speed corresponding to the first stroke gear, R 013 is the speed corresponding to the first low wind gear, the second fan 32 has a second high wind gear, a second medium wind gear and a second low wind gear with decreasing speeds in sequence, R 021 is the speed corresponding to the second highest wind speed, R 022 is the speed corresponding to the second stroke gear, R 023 is the speed corresponding to the second-lowest wind speed. With this setting, when the human activity zone is the first active zone (i.e., the user primarily spends time on the left side), the system sets the speed of the first fan 31 to the speed corresponding to the first-highest wind speed, while the speed of the second fan 32 is reduced to the speed corresponding to the second-medium wind speed. Furthermore, in the third temperature zone, the second fan 32 on the right side stops completely, ensuring that cool air is concentrated in the left active zone while reducing energy consumption on the right side. This control strategy intelligently adjusts the fan speed based on the human activity zone, avoiding excessive air supply in inactive areas and effectively reducing the energy consumption of the air conditioning system. This is especially true when the outdoor ambient temperature is high (in the second and third temperature zones), as effective energy conservation is achieved through rationally controlling the fan speed.

[0122] In one embodiment, after obtaining the outdoor ambient temperature, the control method further includes: when the outdoor ambient temperature is greater than a first preset temperature and less than or equal to a second preset temperature, setting the operating frequency of the air conditioning system's compressor 8 to a first frequency; when the outdoor ambient temperature is greater than the second preset temperature and less than or equal to a third preset temperature, setting the operating frequency of the compressor 8 to a second frequency; and when the outdoor ambient temperature is greater than the third preset temperature, setting the operating frequency of the compressor 8 to a third frequency; wherein the first frequency is greater than the second frequency, and the second frequency is greater than the third frequency. By adopting such a configuration, by dynamically adjusting the operating frequency of the compressor 8 according to the outdoor ambient temperature, the high load operation of the compressor 8 under extreme conditions is reduced, which helps to extend the service life of the air conditioning system and reduce maintenance costs.

[0123] It should be noted that the operating frequency of the compressor corresponding to the first temperature zone is the first frequency, the operating frequency of the compressor corresponding to the second temperature zone is the second frequency, and the operating frequency of the compressor corresponding to the third temperature zone is the third frequency.

[0124] Specifically, the maximum operating frequency of compressor 8 is the maximum operating frequency, wherein the ratio of the first frequency to the maximum operating frequency is greater than 1 / 3 and less than 2 / 3. Thus, by adjusting the operating frequency of compressor 8, the operating load of the air conditioner can be reduced, ensuring reliable operation of the air conditioner even in high outdoor ambient temperatures and avoiding unnecessary overloads or shutdowns.

[0125] Specifically, the maximum operating frequency of compressor 8 is the maximum operating frequency, wherein the ratio of the second frequency to the maximum operating frequency is greater than 1 / 4 and less than 1 / 2. This ensures a certain cooling capacity while reducing the air conditioner's operating load, ensuring reliable operation of the air conditioner even in high outdoor temperatures and avoiding unnecessary overloads or shutdowns.

[0126] Specifically, the maximum operating frequency of compressor 8 is the maximum operating frequency, where the ratio of the third frequency to the maximum operating frequency is greater than 1 / 6 and less than 1 / 3. Thus, setting the upper frequency limit to 1 / 3 of the maximum ensures that the system maintains a certain cooling capacity even in energy-saving mode, avoiding uncomfortable fluctuations in indoor temperature. Simultaneously, setting the lower frequency limit to 1 / 6 of the maximum value minimizes energy consumption, reduces the operating costs of the air conditioning system in relatively mild environments, and ensures stable system operation.

[0127] Specifically, the ratio between the first frequency and the maximum operating frequency is 1 / 2, the ratio between the second frequency and the maximum operating frequency is 1 / 3, and the ratio between the third frequency and the maximum operating frequency is 1 / 5.

[0128] In one embodiment, if Figure 3 As shown, the air-conditioning indoor unit is the air-conditioning indoor unit described above; the left air guide portion 51 of the air-conditioning indoor unit has positions a1, a2, a3, a4, and a5 arranged in sequence in a counterclockwise direction; the right air guide portion 52 of the air-conditioning indoor unit has positions b1, b2, b3, b4, and b5 arranged in sequence in a clockwise direction; wherein the control method further includes: adjusting the rotation angles of the left air guide portion 51 and the right air guide portion 52 according to the human body active area; a method for adjusting the rotation angles of the left air guide portion 51 and the right air guide portion 52 according to the human body active area This includes: when the human body is in the first active area, the left air guide 51 is in position a3; when the human body is in the second active area, the left air guide 51 is in position a4 and the right air guide 52 is in position b5; when the human body is in the third active area, the left air guide 51 is in position a5 and the right air guide 52 is in position b4; when the human body is in the fourth active area, the right air guide 52 is in position b3; and when the human body is in the fifth active area, both the left air guide 51 and the right air guide 52 are in a sweeping state. This configuration ensures that cool air is more precisely delivered to areas with frequent human activity by intelligently adjusting the air guide angle based on the human body's active area, thereby improving the targetedness and efficiency of cooling. Accurate air guide angle adjustment can reduce unnecessary cooling waste, especially in areas where people are less active. By concentrating the cool air in active areas, the overall system load is reduced, achieving energy-saving operation.

[0129] Specifically, if Figure 3 As shown, the first predetermined axis B is the extension direction of the left air outlet 11, the extension direction of the left air guide portion 51 corresponding to position a3 is parallel to the first predetermined axis B, the extension direction of the left air guide portion 51 corresponding to position a2 and the extension direction of the left air guide portion 51 corresponding to position a4 are symmetrical with respect to the direction of the first predetermined axis B, and the extension direction of the left air guide portion 51 corresponding to position a1 and the extension direction of the left air guide portion 51 corresponding to position a5 are symmetrical with respect to the direction of the first predetermined axis B. The second predetermined axis C is the extension direction of the right air outlet 12, the extension direction of the right air guide portion 52 corresponding to position b3 is parallel to the second predetermined axis C, the extension direction of the right air guide portion 52 corresponding to position b2 and the extension direction of the right air guide portion 52 corresponding to position b4 are symmetrical with respect to the direction of the second predetermined axis C, and the extension direction of the right air guide portion 52 corresponding to position b1 and the extension direction of the right air guide portion 52 corresponding to position b5 are symmetrical with respect to the direction of the second predetermined axis C.

[0130] It should be noted that the first air guide position of the left air guide portion is position a3, the second air guide position of the left air guide portion includes mutually symmetrical positions a2 and a4, and the third air guide position of the left air guide portion includes mutually symmetrical positions a1 and a5. The fourth air guide position of the right air guide portion is position b3, the fifth air guide position of the right air guide portion includes mutually symmetrical positions b2 and b4, and the sixth air guide position of the right air guide portion includes mutually symmetrical positions b1 and b5.

[0131] It should be noted that the left air guide part being in the wind sweeping state means that the left air guide part rotates back and forth in the directions of position a1, position a2, position a3, position a4 and position a5 in sequence, and the right air guide part being in the wind sweeping state means that the right air guide part rotates back and forth in the directions of position b1, position b2, position b3, position b4 and position b5 in sequence.

[0132] Specifically, after positioning the left air guide 51 in position a3, the control method further includes: obtaining the outdoor ambient temperature; positioning the right air guide 52 in position b3 when the outdoor ambient temperature is less than or equal to a third preset temperature; and positioning the right air guide 52 in position b1 when the outdoor ambient temperature is greater than the third preset temperature. With this configuration, when the air conditioning system detects that human activity is primarily in the first active zone (the left side), the system adjusts the left air guide 51 to position a3 to ensure that cool air is delivered directly and effectively to the active zone. Furthermore, the position of the right air guide 52 is further adjusted based on the outdoor ambient temperature, achieving a more refined air delivery strategy. When the outdoor temperature is low (less than or equal to the third preset temperature), the right air guide 52 is positioned in position b3, allowing cool air to be more evenly distributed throughout the room and reducing energy waste, particularly outside of the active zone. When the outdoor temperature rises (greater than the third preset temperature), considering the increased cooling demand in the high temperature environment, the right air guide 52 is adjusted to the b1 position, which can reduce the air supply to the top of the room or the remote uninhabited area, thereby more effectively concentrating the cold air under high temperature conditions, meeting the cooling needs of the human activity area, and reducing the overall energy consumption.

[0133] Specifically, after positioning the right air guide 52 in position b3, the control method further includes: obtaining the outdoor ambient temperature; positioning the left air guide 51 in position a3 when the outdoor ambient temperature is less than or equal to a third preset temperature; and positioning the left air guide 51 in position a1 when the outdoor ambient temperature is greater than the third preset temperature. With this configuration, when the air conditioning system detects, via millimeter-wave radar, that human activity is primarily concentrated in areas S1 and S2, i.e., the left active area, the control strategy will initially position the left air guide 51 in position a3, ensuring that cool air reaches the active area directly, thereby improving air supply efficiency where people are located. Under extremely high temperatures, where the outdoor ambient temperature exceeds the third preset temperature, the system adjusts the left air guide 51 to position a1. This wide-angle air supply mode, in which the air guide is angled relative to the air duct, ensures uniform cool air coverage throughout the room, even in the hottest weather. In particular, when people may be moving or dispersed within the room, the a1 position effectively prevents the discomfort of direct cool air blowing on the person, while ensuring a comfortable temperature in all areas, enhancing the user experience under extreme heat stress.

[0134] In one embodiment, the air-conditioning indoor unit is the air-conditioning indoor unit described above; the control method further comprises: obtaining the outdoor ambient temperature; when the outdoor ambient temperature is greater than a first preset temperature, operating the outdoor fan 7 of the air-conditioning system at a preset high wind speed, operating the first fan 31 at a first high wind speed, and operating the second fan 32 at a second high wind speed, making the opening of the first valve body 41 of the air-conditioning indoor unit greater than or equal to the first preset opening, and the opening of the second valve body 42 of the air-conditioning indoor unit greater than or equal to the second preset opening, and making the operating frequency of the compressor 8 of the air-conditioning system be a preset frequency; when the outdoor ambient temperature is less than or equal to the first preset temperature, When the temperature is set, the speeds of the external fan 7, the first fan 31 and the second fan 32 remain unchanged, the openings of the first valve body 41 and the second valve body 42 remain unchanged, and the operating frequency of the compressor 8 remains unchanged; wherein, the first preset temperature is greater than or equal to 37°C and less than or equal to 40°C; the speed corresponding to the preset high wind speed is greater than or equal to 780r / min and less than or equal to 850r / min; the speeds corresponding to the first high wind speed and the second high wind speed are both greater than or equal to 1200r / min and less than or equal to 1350r / min; the first preset opening is P1, P1=P 01 +a,P 01 is the opening of the first valve body 41 corresponding to the rated cooling capacity of the air-conditioning system, and the second preset opening is P2, P2=P 02 +a,P 02 The opening of the second valve body 42 corresponds to the rated cooling capacity of the air-conditioning system, 45%≤a≤55%; the preset frequency is F, F=F0-(T1-T0), F0 is the maximum operating frequency of the compressor 8, T1 is the outdoor ambient temperature, and T0 is the first preset temperature. In this way, when the outdoor ambient temperature is higher than the first preset temperature, indicating that it is in hot weather conditions, the control method immediately adjusts the key parameters of the air-conditioning system to enhance the cooling effect. The external fan 7 operates at the preset high wind speed, which significantly improves the external heat exchange efficiency and is conducive to maintaining good heat dissipation performance in a high temperature environment. At the same time, the first fan 31 and the second fan 32 operate at the first high wind speed and the second high wind speed respectively, which increases the indoor air circulation speed, promotes indoor heat exchange, and improves the cooling efficiency of the air conditioner.

[0135] Specifically, when the outdoor ambient temperature is greater than the first preset temperature, the air conditioner indoor fan (the first fan 31 and the second fan 32) initially runs at the corresponding high wind speed (if the set wind speed is lower than the high wind speed, it runs according to the set wind speed), and the outdoor fan 7 runs at the corresponding high wind speed. At the same time, both expansion valves (the first valve body 41 and the second valve body 42) are opened, and the minimum opening degree in the first 10 minutes is not less than P1, P1=P 01 +50%, F=F0-(T1-40). This ensures that during the startup of the entire unit, the outdoor pipe temperature will not be too high due to heavy load, resulting in overload shutdown, which will affect the cooling of the air conditioner.

[0136] Specifically, when the outdoor ambient temperature is greater than the first preset temperature, if the speed corresponding to the set wind speed of the outdoor fan 7 is greater than the speed corresponding to the preset high wind speed, the outdoor fan 7 is operated at its set wind speed; if the speed corresponding to the set wind speed of the first fan 31 is greater than the speed corresponding to the first high wind speed, the first fan 31 is operated at its set wind speed; if the speed corresponding to the set wind speed of the second fan 32 is greater than the speed corresponding to the second high wind speed, the second fan 32 is operated at its set wind speed.

[0137] Specifically, if the first preset opening is greater than the maximum opening of the first valve body 41, then when the outdoor ambient temperature is greater than the first preset temperature, the opening of the first valve body 41 is set to its maximum opening. If the second preset opening is greater than the maximum opening of the second valve body 42, then when the outdoor ambient temperature is greater than the first preset temperature, the opening of the second valve body 42 is set to its maximum opening.

[0138] In one embodiment, before obtaining the activity zone where a person is located, the control method further includes: obtaining the indoor ambient temperature; comparing the indoor ambient temperature with a preset indoor temperature; when the difference between the indoor ambient temperature and the preset indoor temperature is less than or equal to a preset differential temperature, causing the person position detector 10 of the air conditioner indoor unit to enter a detection state; and when the difference between the indoor ambient temperature and the preset indoor temperature is greater than a preset differential temperature, causing the person position detector 10 of the air conditioner indoor unit to enter a standby state or a shutdown state. The preset differential temperature is greater than or equal to 1°C and less than or equal to 3°C. With this configuration, the control method first obtains the indoor ambient temperature and compares it with the preset indoor temperature. Only when the difference between the indoor ambient temperature and the preset indoor temperature is the person position detector 10 activated to enter a detection state. When the difference between the indoor ambient temperature and the preset indoor temperature is greater than the preset differential temperature, the air conditioning system determines that the indoor temperature is still in the early stages of cooling, and the person position detector 10 is set to a standby state or a shutdown state. This means that when the indoor temperature is high and the air conditioning system is working at full capacity to cool the room to the preset temperature, the system temporarily does not need to detect the person's location. This strategy effectively avoids the inaccuracy of human position detection caused by the large indoor temperature difference in the early cooling stage, and at the same time reduces the energy consumption of the system when running the human position detection component 10 during non-essential periods, achieving more energy-efficient operation. Specifically, the preset temperature difference is 2°C.

[0139] It should be noted that the detection state refers to the human body position detection element 10 being able to immediately obtain the human body position. The standby state refers to the human body position detection element 10 being powered on but not in the detection state. The shutdown state refers to the human body position detection element 10 being unpowered.

[0140] In one embodiment, the air-conditioning indoor unit is the above-mentioned air-conditioning indoor unit, and the air-conditioning indoor unit further includes a first valve body 41 and a second valve body 42 . The control method further includes: obtaining an operating frequency of a compressor 8 of the air-conditioning system; continuously obtaining a refrigerant temperature of a condenser 6 of the air-conditioning system when the operating frequency of the compressor 8 reaches a minimum operating frequency; when the refrigerant temperature of the condenser 6 is greater than or equal to a preset outdoor refrigerant temperature and the refrigerant temperature of the condenser 6 is in a continuously rising state, reducing the speed of the first fan 31 and the speed of the second fan 32 by a preset number of revolutions per minute, and increasing the opening of the first valve body 41 of the air-conditioning indoor unit and the opening of the second valve body 42 of the air-conditioning indoor unit by a preset number of revolutions per minute; when the refrigerant temperature of the condenser 6 is less than a preset outdoor refrigerant temperature or the refrigerant temperature of the condenser 6 is not in a continuously rising state, maintaining the speed of the first fan 31 and the speed of the second fan 32 unchanged, and maintaining the opening of the first valve body 41 and the opening of the second valve body 42 unchanged; wherein the preset outdoor refrigerant temperature is greater than or equal to 56° C. and less than or equal to 60° C., the preset number of revolutions is greater than or equal to 8r and less than or equal to 12r, and the preset opening is greater than or equal to 1% and less than or equal to 3%. With this setup, when the air conditioning system is operating at the lowest operating frequency of compressor 8, by monitoring the refrigerant temperature of condenser 6, if the refrigerant temperature continues to rise and reaches or exceeds the preset outdoor refrigerant temperature, the system will automatically adjust the speed of the first fan 31 and the second fan 32 to reduce, while gradually increasing the opening of the first valve body 41 and the second valve body 42. This intelligent adjustment mechanism can avoid system high pressure abnormalities caused by reduced refrigerant circulation efficiency in low-frequency operation, maintaining the stability and reliability of the system. Specifically, the preset outdoor refrigerant temperature is 56°C, the preset speed is 10r, and the preset opening is 2%.

[0141] It should be noted that the refrigerant temperature of the condenser 6 being in a continuously rising state means that the current refrigerant temperature of the condenser 6 is greater than the refrigerant temperature of the condenser 6 in the previous minute.

[0142] Specifically, under different temperature zones, the fan speed, valve body opening, air guide portion position and compressor 8 frequency corresponding to different active areas are shown in the following table.

[0145] By using the control device provided in one embodiment of the present invention, the refrigerant flow rate and fan speed are adjusted according to the human activity zone, ensuring that the cooling capacity of the air conditioning system is accurately delivered to the area near the human body, avoiding the waste of cooling capacity in uninhabited areas, thereby improving cooling efficiency.

By dynamically adjusting the refrigerant flow rate of the first and second heat exchange units, as well as the speeds of the first and second fans 31 and 32, according to the actual human activity zone, the air conditioning system avoids overcooling in inactive areas, achieving more efficient energy utilization and reducing energy consumption during air conditioning operation. Furthermore, as the human activity zone changes, the air conditioner indoor unit can also respond quickly, adjusting the refrigerant flow rate and fan speed, ensuring that the air conditioning system can always adapt to immediate environmental changes and provide the best cooling effect.
