[0090] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0091] like Figures 1 to 3 As shown, an embodiment of the present invention provides an indoor air conditioner unit, which includes an indoor unit body 1, an evaporator 2, a first fan 31, and a second fan 32. The indoor unit body 1 has an inner cavity, a left air outlet 11, and a right air outlet 12. The evaporator 2, the first fan 31, and the second fan 32 are all disposed within the inner cavity. The evaporator 2 includes a first heat exchange section and a second heat exchange section. The air inlet of the first fan 31 is connected to the air outlet side of the first heat exchange section, and the air inlet of the second fan 32 is connected to the air outlet side of the second heat exchange section. The air outlet of the first fan 31 is connected to the left air outlet 11, and the air outlet of the second fan 32 is connected to the right air outlet 12. The indoor unit of the air conditioner also includes a human position detection device 10 and a control device, both of which are mounted on the main body 1 of the indoor unit. The human position detection device 10, the evaporator 2, the first fan 31 and the second fan 32 are all connected to the control device. The control device is used to control the refrigerant flow rate of the first heat exchange section and the second heat exchange section and / or the rotation speed of the first fan 31 and the second fan 32 according to the human position detected by the human position detection device 10.

[0092] The air conditioner indoor unit provided by the embodiment of the present application can dynamically adjust the refrigerant flow and the fan rotating speed on both sides of the air conditioner indoor unit according to the human activity position by subdividing the evaporator 2 into a first heat exchange part and a second heat exchange part and connecting the first heat exchange part and the second heat exchange part with the first fan 31 and the second fan 32 respectively (the end of the evaporator 2 relatively close to the first fan 31 is the first heat exchange part, and the end of the evaporator 2 relatively close to the second fan 32 is the second heat exchange part). This structure and control mode can more accurately deliver cold energy to the human activity area, improve the refrigeration efficiency, and especially in a high-temperature environment, can effectively improve the refrigeration capacity of the air conditioner. By monitoring the activity range of the human body in the room through the human position detection member 10, the refrigerant flow and the fan rotating speed in the inactive area can be intelligently adjusted, and the waste of cold energy in unnecessary areas is avoided, thereby reducing the energy consumption of the air conditioner. Through the linkage of the human position detection member 10 and the control member, intelligent control of the air conditioner indoor unit is realized, so as to automatically adapt to the change of human activity in the room and avoid invalid air outlet in the area without human activity. By making the air outlet of the air conditioner indoor unit more suitable for the human activity distribution in the room, the refrigeration efficiency of the air conditioner is further improved. Therefore, the air conditioner indoor unit provided by the embodiment can solve the problem of low refrigeration efficiency of the air conditioner system in the prior art in a high-temperature environment.

[0093] Specifically, the air conditioner indoor unit is a cabinet type air conditioner indoor unit.

[0094] Specifically, the left air outlet 11 and the right air outlet 12 are arranged on the left side and the right side of the air conditioner indoor unit respectively. The first fan 31 is arranged corresponding to the left air outlet 11 to adjust the air outlet amount of the left air outlet 11 by adjusting the rotating speed of the first fan 31, and the second fan 32 is arranged corresponding to the right air outlet 12 to adjust the air outlet amount of the right air outlet 12 by adjusting the rotating speed of the second fan 32. The first heat exchange part is arranged corresponding to the left air outlet 11 to adjust the air outlet coldness of the left air outlet 11 by adjusting the refrigerant flow of the first heat exchange part, and the second heat exchange part is arranged corresponding to the right air outlet 12 to adjust the air outlet coldness of the right air outlet 12 by adjusting the refrigerant flow of the second heat exchange part.

[0095] In an embodiment, the air conditioner indoor unit further comprises a first valve body 41, which is arranged on the first heat exchange part, and the opening degree of the first valve body 41 is adjustably arranged to adjust the refrigerant flow of the first heat exchange part; the first valve body 41 is connected with the control member, and the control member is used to control the opening degree of the first valve body 41 according to the human body position detected by the human body position detection member 10. With such a structure, the opening degree adjustment mechanism of the first valve body 41 can intelligently adjust the refrigerant flow of the first heat exchange part according to the human body position information detected by the human body position detection member 10. This means that when the human body is located in the left area of the room (related to the first fan 31 and the first heat exchange part), the system can increase the refrigerant flow on the left side to improve the cooling efficiency of this area and ensure that the temperature of the area where the human body is located drops rapidly. By controlling the opening degree of the first valve body 41, the refrigerant flow in the area where no one is active can be reduced to avoid unnecessary cooling and thus reduce the overall energy consumption.

When the human activity is mainly concentrated on the right side of the room, the control member can accurately adjust the right air guide part 52 according to the information of the human body position detection member 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 part 52 allows the system to adjust the flow-through section of the cold air according to the actual demand of the right side area, thereby reducing the distribution of cold energy in the unoccupied area and achieving more refined energy consumption management.

[0100] In an embodiment, the air conditioner indoor unit further comprises a left air guide part 51 and a right air guide part 52. The left air guide part 51 is rotatably arranged at the left air outlet 11 to adjust the flow-through section of the left air outlet 11 for air conditioner air to flow out; the left air guide part 51 is connected with the control member, and the control member is configured to control the rotation angle of the left air guide part 51 according to the detection result of the human body position detection member 10.

With such a structure, the rotation angle of the left air guide part 51 can be intelligently adjusted by the control member to ensure that the cold air can be accurately directed to the left side area where the human activity is based on the detection result of the human body position detection member 10. This not only improves the cooling efficiency and makes the cold air directly reach the area that needs to be cooled, but also enhances the user's comfort and avoids the discomfort of direct blowing of cold air. By adjusting the rotation angle of the left air guide part 51, the flow direction and the size of the flow-through section of the cold air can be effectively controlled, the waste of cold energy in the unoccupied area can be reduced, and the overall energy consumption of the air conditioning system can be reduced. The right air guide part 52 can intelligently adjust its rotation angle to achieve targeted air supply to the right side area. When the human activity is mainly concentrated on the right side of the room, the control member can accurately adjust the right air guide part 52 according to the information of the human body position detection member 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 part 52 allows the system to adjust the flow-through section of the cold air according to the actual demand of the right side area, thereby reducing the distribution of cold energy in the unoccupied area and achieving more refined energy consumption management.

[0101] Specifically, the left air guide part 51 comprises a plurality of left air guide plates arranged in sequence and at intervals, and a left flow-through channel for air conditioner air to flow out is formed between adjacent two left air guide plates. The right air guide part 52 comprises a plurality of right air guide plates arranged in sequence and at intervals, and a right flow-through channel for air conditioner air to flow out is formed between adjacent two right air guide plates.

[0102] Specifically, the left air vent 11 extends along a first preset direction; the left air guide 51 has a first air guide position, a second air guide position, and a third air guide position; when the left air guide 51 is in the first air guide position, its extension direction is parallel to the first preset direction; when the left air guide 51 is in the second air guide position, its extension direction is at a first preset angle to the first preset direction; when the left air guide 51 is in the third air guide position, its extension direction is at a second preset angle to the first preset direction. The first preset angle is greater than or equal to 10° and less than or equal to 15°; the second preset angle is greater than or equal to 30° and less than or equal to 45°. Thus, the left air guide 51 can precisely control the direction of the cold air through its parallel position to the first preset direction (first air guide position), its first preset angle position (10° to 15° to the first preset direction, second air guide position), and its second preset angle position (30° to 45° to the first preset direction, third air guide position). This multi-layered airflow angle adjustment ensures that the cool air can be delivered more effectively to the left side area according to the position of the human body, thus improving the cooling efficiency.

[0103] Specifically, the right air vent 12 extends along a second preset direction; the right air guide 52 has a fourth air guide position, a fifth air guide position, and a sixth air guide position; when the right air guide 52 is in the fourth air guide position, its extension direction is parallel to the second preset direction; when the right air guide 52 is in the fifth air guide position, its extension direction forms a third preset angle with the second preset direction; when the right air guide 52 is in the sixth air guide position, its extension direction forms a fourth preset angle with the second preset direction. The third preset angle is greater than or equal to 10° and less than or equal to 15°; the fourth preset angle is greater than or equal to 30° and less than or equal to 45°. Thus, the right air guide 52, through its fourth, fifth, and sixth air guide positions, can precisely guide cold air to the right side of the body's activity area, 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 changes in the position of human movement, providing a more personalized and comfortable cooling experience.

[0104] In an embodiment, the indoor unit of the air conditioner further comprises an indoor temperature detection member, a detection end of the indoor temperature detection member is arranged on the indoor unit main body 1, the indoor temperature detection member is used for detecting an indoor temperature, and the indoor temperature detection member is connected with the control member, and the control member is used for controlling whether the human body position detection member 10 performs detection according to a detection result of the indoor temperature detection member. By adopting such a structural arrangement, through the cooperation of the indoor temperature detection member and the control member, intelligent control based on the indoor temperature can be realized. When the indoor temperature has been reduced to a set comfortable temperature range, the control member can automatically stop the operation of the human body position detection member 10, so as to avoid unnecessary position detection in the case where the temperature is already suitable, thereby saving energy consumption. In the case where the indoor temperature has met the demand, the control member stops the operation of the human body position detection member 10, which not only saves energy, but also reduces unnecessary work of the human body position detection member 10, thereby reducing hardware wear and maintenance cost.

[0105] In an embodiment, the indoor unit main body 1 is arranged on a mounting base, and the human body position detection member 10 is arranged on a side of the indoor unit main body 1 away from the mounting base and between the left air outlet 11 and the right air outlet 12. By adopting such a structural arrangement, the human body position detection member 10 is arranged on the side of the indoor unit main body 1 away from the mounting base and between the left air outlet 11 and the right air outlet 12, so that the sensor can have the best detection field of view and angle, thereby more accurately and comprehensively identifying the activity position of the human body in the room. Such a layout design overcomes the detection blind area or error caused by improper position of the traditional human body position detection member 10, and improves the accuracy of human body position detection.

[0106] In an embodiment, the human body position detection member 10 is a millimeter wave radar structure. The millimeter wave radar structure works by using transmission and detection of electromagnetic waves. When electromagnetic waves encounter an obstacle, they are reflected. If these reflected waves are received again at their origin, it means that the obstacle is in the propagation direction. For example, the millimeter wave radar emits electromagnetic waves in all directions within a 120° range in front of the air conditioner from the origin of the air conditioner. When reflected waves are received back in the first region S1, it means that there is a person in the first region S1, and the distance between the person and the air conditioner is calculated according to the emission and reception times.

[0107] As shown in FIG. 1, Figure 4 An embodiment of the present application provides an air conditioner system, which comprises the above-mentioned air conditioner indoor unit, a condenser 6, an external fan 7 and a compressor 8. The air conditioner indoor unit, the condenser 6 and the compressor 8 are connected in sequence, and the external fan 7 is arranged on one side of the condenser 6.

[0108] The air conditioning system provided by the embodiment of the present application can dynamically adjust the refrigerant flow and the fan rotating speed of the two sides of the air conditioning indoor unit according to the human activity position by subdividing the evaporator 2 into the first heat exchange part and the second heat exchange part and connecting the first heat exchange part and the second heat exchange part with the first fan 31 and the second fan 32 respectively. The structure and the control mode can more accurately deliver the cold quantity to the human activity area, improve the refrigeration efficiency, and especially in the high-temperature environment, can effectively improve the refrigeration capacity of the air conditioner. The activity range of the human body in the room can be monitored by the human position detection member 10, and the refrigerant flow and the fan rotating speed of the inactive area can be intelligently adjusted, so as to avoid the waste of the cold quantity in the unnecessary area, thereby reducing the energy consumption of the air conditioner. Through the linkage of the human position detection member 10 and the control member, the intelligent control of the air conditioning indoor unit is realized, so as to automatically adapt to the change of the human activity in the room, avoid the invalid air outlet of the area without human activity, and make the air outlet of the air conditioning indoor unit more suitable for the human activity distribution in the room, thereby further improving the refrigeration efficiency of the air conditioner. Therefore, the air conditioning system provided by the embodiment can solve the problem of low refrigeration efficiency of the air conditioning system in the prior art in the high-temperature environment.

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

[0110] As shown in Figure 5 and Figure 6 , the embodiment of the present application provides a control method, the control method is suitable for the above-mentioned air conditioning system, and the control method comprises the following steps: dividing the room where the air conditioning indoor unit is located into a plurality of 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; obtaining the activity area where the human position is located to obtain the human active area; and adjusting the refrigerant flow of the first heat exchange part and the second heat exchange part of the air conditioning indoor unit and / or the rotating speed of the first fan 31 and the second fan 32 of the air conditioning indoor unit according to the human active area.

[0111] The control method provided by the embodiment of the present application can ensure that the refrigerating capacity of the air conditioning system is accurately delivered to the area near the human body by dividing the room into multiple active areas and adjusting the refrigerant flow and the fan speed according to the active area of the human body, thereby avoiding the waste of cold energy in the non-active area and improving the refrigerating efficiency, especially in a high-temperature environment, the intelligent control can significantly improve the refrigerating performance of the air conditioner. The refrigerant flow of the first heat exchange part and the second heat exchange part and the speed of the first fan 31 and the second fan 32 are dynamically adjusted according to the actual active area of the human body, thereby avoiding excessive refrigeration of the air conditioning system in the non-active area, achieving more effective energy utilization, and reducing the energy consumption of the air conditioner. Moreover, as the active area of the human body changes, the indoor unit of the air conditioner can quickly respond to adjust the refrigerant flow and the fan speed, so that the air conditioning system can always adapt to the immediate environmental changes and provide the best refrigerating effect. Therefore, the control method provided by the embodiment can solve the problem of low refrigerating efficiency of the air conditioning system in the prior art in a high-temperature environment.

[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 along the direction from the left air outlet 11 to the right air outlet 12; when the human body position appears in the first area and the second area, the human body active area is a first active area; when the human body position appears in the second area and the third area, the human body active area is a second active area; when the human body position appears in the third area and the fourth area, the human body active area is a third active area; when the human body position appears in the fourth area and the fifth area, the human body active area is a fourth active area; when the human body position appears in each area, the human body active area is a fifth active area. The method for adjusting the refrigerant flow of the first heat exchange part and the second heat exchange part according to the human body active area includes: when the human body active area is the first active area, the refrigerant flow of the first heat exchange part is greater than that of the second heat exchange part; when the human body active area is the second active area, the third active area or the fifth active area, the refrigerant flow of the first heat exchange part is equal to that of the second heat exchange part; when the human body active area is the fourth active area, the refrigerant flow of the first heat exchange part is less than that of the second heat exchange part. In this way, when the human body active area is the first active area (the human body is located on the left side), the system increases the refrigerant flow of the first heat exchange part to realize efficient cooling in the left area and meet the cooling demand of the user on the left side. When the human body active area is the second, third or fifth active area (the human body is located in the center or is scattered), the refrigerant flow is evenly distributed between the first and second heat exchange parts, ensuring uniform temperature distribution in the whole room and avoiding local overcooling or overheating. When the human body active area is the fourth active area (the human body is located on the right side), the system increases the refrigerant flow of the second heat exchange part to enhance the cooling effect on the right side and adapt to the cooling demand of the user on the right side. Since the adjustment of the refrigerant flow is based on the human body active area, this intelligent control method can greatly reduce the waste of refrigerant in the non-active area of the air conditioner, reduce energy consumption, achieve the goal of energy saving and emission reduction, and the effect is more significant in high temperature environment.

[0113] Specifically, the active area includes a first area, a second area, a third area, a fourth area and a fifth area arranged in sequence along the direction from the left air outlet 11 to the right air outlet 12; when the human body position appears in the first area and the second area, the human body active area is a first active area; when the human body position appears in the second area and the third area, the human body active area is a second active area; when the human body position appears in the third area and the fourth area, the human body active area is a third active area; when the human body position appears in the fourth area and the fifth area, the human body active area is a fourth active area; when the human body position appears in each area, the human body active area is a fifth active area. The method for adjusting the rotating speed 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, the rotating speed of the first fan 31 is greater than that of the second fan 32; when the human body active area is the second active area, the third active area or the fifth active area, the rotating speed of the first fan 31 is equal to that of the second fan 32; when the human body active area is the fourth active area, the rotating speed of the first fan 31 is less than that of the second fan 32. In this way, the user mainly moves in the first active area (left side), and the first fan 31 will run at a higher rotating speed, thereby increasing the cold air delivery strength and creating a more cool environment for the user. When the human body active area is in the center or scattered (second, third or fifth active area), the first fan 31 and the second fan 32 will maintain the same rotating speed, avoiding energy waste caused by excessive air supply, while ensuring uniform distribution of indoor temperature. When the human body active area moves to the right side of the room (fourth active area), the rotating speed of the second fan 32 will be higher than that of the first fan 31 to adapt to the change of the user's position and ensure effective coverage of the cold air, which reflects the high flexibility of the air conditioner control method in indoor temperature regulation. When the human body active area changes, dynamically adjusting the rotating speed of the fan can avoid excessive air supply in the non-active area, thereby reducing the energy consumption of the air conditioning system during peak period, helping to smoothly pass through the high temperature period and reducing the energy consumption peak.

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

[0115] Specifically, the human active area being the first active area means that the activity track of the human position is in the first area S1 and the second area S2; the human active area being the second active area means that the activity track of the human position is in the second area S2 and the third area S3; the human active area being the third active area means that the activity track of the human position is in the third area S3 and the fourth area S4; the human active area being the fourth active area means that the activity track of the human position is in the fourth area S4 and the fifth area S5; the human active area being the fifth active area means that the activity track of the human position is in the first area S1, the second area S2, the third area S3, the fourth area S4 and the fifth area S5, and is relatively dispersed and not concentrated in a certain area range.

[0116] In an embodiment, before adjusting the refrigerant flow of the first heat exchange part and the second heat exchange part and / or the rotation speed of the first fan 31 and the second fan 32 according to the human active area, the control method further comprises: obtaining the outdoor environment temperature; determining the refrigerant flow of the first heat exchange part and the second heat exchange part corresponding to different human active areas and / or the rotation speed of the first fan 31 and the second fan 32 corresponding to different human active areas according to the size of the outdoor environment temperature. With such a setting, by pre-obtaining the outdoor environment temperature and determining the refrigerant flow of the first heat exchange part and the second heat exchange part corresponding to the human active area and the rotation speed of the first fan 31 and the second fan 32 according to the specific temperature value, the scheme can more accurately cope with high temperature environment, ensure that the air conditioning system can provide a cooling effect meeting the human comfort requirement under different outdoor temperatures, and improve the adaptability and efficiency of the system under extreme weather conditions. According to different outdoor temperatures, the cooling intensity of the human active area is intelligently adjusted to provide users with more personalized, comfortable and efficient cooling experience.

[0117] Specifically, when the outdoor environment temperature is greater than a first preset temperature and less than or equal to a second preset temperature, the outdoor environment temperature is in a first temperature zone; when the outdoor environment temperature is greater than the second preset temperature and less than or equal to a third preset temperature, the outdoor environment temperature is in a second temperature zone; when the outdoor environment temperature is greater than the third preset temperature, the outdoor environment temperature is in a third temperature zone; wherein: the method for determining the refrigerant flow of the first heat exchange part and the second heat exchange part corresponding to different human active areas according to the size of the outdoor environment temperature comprises: when the human active area is a first active area, making Q 11 21 31 12 22 32 ; when the human active area is a second active area, a third active area or a fifth active area, making Q 11 21 31 12 22 32 ; when the human active area is a fourth active area, making Q 12 22 32 11 21 31 Q 11 is the refrigerant flow of the first heat exchange part corresponding to the first temperature zone, Q 21 is the refrigerant flow of the first heat exchange part corresponding to the second temperature zone, Q 31 is the refrigerant flow of the first heat exchange part corresponding to the third temperature zone, and Q 12 ​​​​​​​​​​​​​​​Q 22 Q 32 Q 11 is the refrigerant flow rate of the second heat exchange part corresponding to the third temperature zone. With such a configuration, by dividing the outdoor environment temperature into the first temperature zone, the second temperature zone and the third temperature zone, and adjusting the refrigerant flow rate of the first heat exchange part and the second heat exchange part according to the human active area under each temperature zone, it can be ensured that the air conditioning system can provide the most suitable cooling capacity for human body under different outdoor temperatures. In the lower temperature zone (the first temperature zone), the refrigerant flow rate near the human active area is relatively small, while in the higher temperature zone (the second temperature zone and the third temperature zone), the refrigerant flow rate gradually increases with the increase of temperature. Such differentiated control strategy can effectively reduce the energy consumption of the air conditioner when the outdoor temperature is suitable, and realize the effect of intelligent energy saving, especially in the high temperature season, unnecessary energy waste is avoided.

[0118] Specifically, when the outdoor environment temperature is greater than the first preset temperature and less than or equal to the second preset temperature, the outdoor environment temperature is in the first temperature zone; when the outdoor environment temperature is greater than the second preset temperature and less than or equal to the third preset temperature, the outdoor environment temperature is in the second temperature zone; when the outdoor environment temperature is greater than the third preset temperature, the outdoor environment temperature is in the third temperature zone; wherein: the method for determining the rotating speed of the first fan 31 and the second fan 32 corresponding to different human active areas according to the size of the outdoor environment temperature comprises: when the human active area is the first active area, making R 11 21 31 12 22 32 ; when the human active area is the second active area, the third active area or the fifth active area, making R 11 21 31 12 22 ; when the human active area is the fourth active area, making R 32 12 22 32 11 21 31 R 11 is the rotating speed of the first fan 31 corresponding to the first temperature zone, R 21 is the rotating speed of the first fan 31 corresponding to the second temperature zone, R 31 is the rotating speed of the first fan 31 corresponding to the third temperature zone, R 12 is the rotating speed of the second fan 32 corresponding to the first temperature zone, R 22 is the rotating speed of the second fan 32 corresponding to the second temperature zone, R​​​​​​​​​​​​​32 The rotation speed of the second fan 32 corresponding to the third temperature zone. With such a setting, through the hierarchical control of the outdoor environment temperature (the first temperature zone, the second temperature zone, and the third temperature zone), the embodiment of the present application can dynamically adjust the rotation speeds of the first fan 31 and the second fan 32, so as to ensure that the rotation speeds of the fans match the active areas of the human body under different temperature zones, and improve the refrigeration efficiency and the energy conversion rate. The intelligent analysis and regulation of the outdoor environment temperature enable the air conditioning system to better adapt to the fluctuations of the external environment, especially under the high-temperature condition in summer, and the dynamic adjustment mechanism can ensure the efficient, stable, and comfortable operation of the air conditioner.

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

[0120] Specifically, the method for determining the refrigerant flow of the first heat exchange part and the second heat exchange part corresponding to different active areas of the human body according to the size of the outdoor environment temperature comprises: when the active area of the human body is the first active area, Q 11 21 31 01 12 02 22 02 32 11 01 12 02 21 31 01 22 32 02 12 22 32 02 11 01 21 01 31 01 02 ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The refrigerant flow rate of the second heat exchange portion corresponding to the rated cooling capacity of the air conditioning system. With such a setting, the first active area (left body active), the system maintains the refrigerant flow rate of the first heat exchange portion at the rated value, while significantly reducing or closing the refrigerant flow rate of the second heat exchange portion, which ensures that cold air can be concentrated to supply to the body active area, maximizing the refrigeration efficiency. In the second, third and fifth active areas, the refrigerant flow rates of the first heat exchange portion and the second heat exchange portion are set to be equally distributed, which can cover a wide range of body active areas and avoid excessive energy consumption, embodying the strategy of efficient use of energy and energy-saving operation. The fourth active area (right body active), the refrigerant flow rate of the second heat exchange portion is set to the rated value, while the refrigerant flow rate of the first heat exchange portion is significantly reduced or even closed. This targeted adjustment of refrigerant flow rate can provide personalized cooling experience according to the changes in the body active area, ensuring that the cold air is accurately delivered to the user's location and improving comfort. By fine management of the refrigerant flow rate, it avoids excessive refrigeration in the inactive area, thereby reducing the overall load of the air conditioning system, reducing the risk of equipment overload due to high temperature environment, prolonging the service life of the system and reducing the maintenance cost.

[0121] Specifically, the method for determining the rotation speed of the first fan 31 and the second fan 32 corresponding to different body active areas according to the size of the outdoor environment temperature comprises: when the body active area is the first active area, R 11 =R 21 =R 31 =R 011 , R 12 =R 22 =R 023 , R 32 =0; when the 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 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 gear, a first medium wind gear and a first low wind gear with decreasing rotation speed, R 011 is the rotation speed corresponding to the first high wind gear, R 012R is the rotating speed corresponding to the first high wind gear 013 R is the rotating speed corresponding to the first low wind gear, the second fan 32 has the second high wind gear, the second middle wind gear and the second low wind gear with the rotating speed decreasing in turn, R 021 R is the rotating speed corresponding to the second high wind gear, R 022 R is the rotating speed corresponding to the second middle wind gear, R 023 R is the rotating speed corresponding to the second low wind gear. With such a setting, when the human active area is the first active area (i.e. the user mainly moves on the left side), the rotating speed of the first fan 31 is set to the rotating speed corresponding to the first high wind gear, while the rotating speed of the second fan 32 is reduced to the rotating speed corresponding to the second middle wind gear, and when the third temperature zone, the second fan 32 on the right side is completely stopped, ensuring that the cold air is concentratedly supplied to the left active area, while reducing the energy consumption on the right side. The control strategy intelligently adjusts the rotating speed of the fan according to the human active area, avoids excessive air supply in the non-active area, effectively reduces the energy consumption of the air conditioning system, and especially in the case of high outdoor environment temperature (the second temperature zone and the third temperature zone), by reasonably controlling the rotating speed of the fan, effective energy saving is realized.

[0122] In an embodiment, after obtaining the outdoor environment temperature, the control method further comprises: when the outdoor environment temperature is greater than a first preset temperature and less than or equal to a second preset temperature, the operating frequency of the compressor 8 of the air conditioning system is the first frequency; when the outdoor environment temperature is greater than the second preset temperature and less than or equal to a third preset temperature, the operating frequency of the compressor 8 is the second frequency; when the outdoor environment temperature is greater than the third preset temperature, the operating frequency of the compressor 8 is the third frequency; wherein the first frequency is greater than the second frequency, and the second frequency is greater than the third frequency. With such a setting, by dynamically adjusting the operating frequency of the compressor 8 according to the outdoor environment temperature, the high load operation of the compressor 8 under extreme conditions is reduced, which helps to prolong the service life of the air conditioning system and reduce the maintenance cost.

[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 value of the operating frequency of the compressor 8 is the maximum operating frequency, wherein the ratio between the first frequency and the maximum operating frequency is greater than 1 / 3 and less than 2 / 3. In this way, by adjusting the operating frequency of the compressor 8, the air conditioning operating load can be reduced to ensure that the air conditioner can reliably operate under high outdoor environment temperature, avoiding unnecessary overload or shutdown.

[0125] Specifically, the maximum operating frequency of compressor 8 is the maximum operating frequency, wherein the ratio between the second frequency and the maximum operating frequency is greater than 1 / 4 and less than 1 / 2. In this way, a certain amount of cooling capacity is guaranteed while reducing the operating load of the air conditioner, ensuring reliable operation of the air conditioner even when the outdoor ambient temperature is high, and avoiding unnecessary overload or shutdown.

[0126] Specifically, the maximum operating frequency of compressor 8 is the maximum operating frequency, where the ratio between the third frequency and 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 value ensures that the system maintains a certain cooling capacity even in energy-saving mode, avoiding uncomfortable changes in indoor temperature. Simultaneously, by setting the lower frequency limit to 1 / 6 of the maximum value, energy consumption is minimized, reducing the operating costs of the air conditioning system in milder environments and ensuring 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, such as Figure 3 As shown, the indoor unit of the air conditioner is the aforementioned indoor unit; the left air guide section 51 of the indoor unit has positions a1, a2, a3, a4, and a5 arranged sequentially in a counterclockwise direction; the right air guide section 52 of the indoor unit has positions b1, b2, b3, b4, and b5 arranged sequentially in a clockwise direction; wherein, the control method further includes: adjusting the rotation angle of the left air guide section 51 and the right air guide section 52 according to the active area of ​​the human body; the method for adjusting the rotation angle of the left air guide section 51 and the right air guide section 52 according to the active area of ​​the human body. This includes: when the active human body area is the first active area, the left air guide 51 is positioned at position a3; when the active human body area is the second active area, the left air guide 51 is positioned at position a4, and the right air guide 52 is positioned at position b5; when the active human body area is the third active area, the left air guide 51 is positioned at position a5, and the right air guide 52 is positioned at position b4; when the active human body area is the fourth active area, the right air guide 52 is positioned at position b3; and when the active human body area is the fifth active area, both the left air guide 51 and the right air guide 52 are in a swing state. This setup, by intelligently adjusting the rotation angle of the air guides according to the active human body area, ensures that cold air is delivered more precisely to areas with frequent human activity, thereby improving the targeting and efficiency of cooling. Accurate air guide angle adjustment reduces unnecessary waste of cooling capacity, especially in areas where people are not active. By concentrating the cold air to the active area, the overall system load is reduced, achieving energy-saving operation.

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

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

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

[0132] Specifically, after the left air guide part 51 is in the a3 position, the control method further comprises: obtaining the outdoor environment temperature; when the outdoor environment temperature is less than or equal to the third preset temperature, the right air guide part 52 is in the b3 position; when the outdoor environment temperature is greater than the third preset temperature, the right air guide part 52 is in the b1 position. With such a setting, when the air conditioning system detects that the human body is mainly active in the first active area (left side), the system adjusts the left air guide part 51 to the a3 position to ensure that the cold air can directly and effectively reach the human activity area. On this basis, the position of the right air guide part 52 is further adjusted according to the outdoor environment temperature, realizing the refinement of the air supply strategy. When the outdoor temperature is low (less than or equal to the third preset temperature), the right air guide part 52 is set to the b3 position, which allows the cold air to be more evenly distributed in the room, reducing energy waste, especially in places other than the human activity area. When the outdoor temperature rises (greater than the third preset temperature), considering the increased cooling demand in high-temperature environments, the right air guide part 52 is adjusted to the b1 position, which can reduce air supply to the top or remote areas of the room, thereby more effectively concentrating cold air in high-temperature conditions to meet the cooling needs of the human activity area while reducing overall energy consumption.

[0133] Specifically, after the right air guide part 52 is in the b3 position, the control method further comprises: obtaining the outdoor environment temperature; when the outdoor environment temperature is less than or equal to the third preset temperature, the left air guide part 51 is in the a3 position; when the outdoor environment temperature is greater than the third preset temperature, the left air guide part 51 is in the a1 position. With such a setting, when the air conditioning system detects that the human body activity is mainly concentrated in the S1, S2 area, i.e. the left active area, through the millimeter wave radar, the control strategy will first place the left air guide part 51 in the a3 position to ensure that the cold air reaches the active area and improve the air supply efficiency at the human body location. In extreme high-temperature conditions where the outdoor environment temperature is higher than the third preset temperature, the system adjusts the left air guide part 51 to the a1 position, which is a wide-angle air supply mode with the air guide part and the air duct at a certain angle, aiming to ensure that even in the hottest weather, the entire room can have uniform cold air coverage, especially when the human body may move or disperse within the room, the a1 position can effectively avoid the discomfort of direct blowing of cold air on the human body, while ensuring the temperature comfort of all areas, improving the user experience in extreme heat stress.

[0134] In an embodiment, the air conditioner indoor unit is the air conditioner indoor unit described above; the control method further comprises: obtaining the outdoor environment temperature; when the outdoor environment temperature is greater than a first preset temperature, causing the outdoor fan 7 of the air conditioning system to operate at a preset high wind speed, the first fan 31 to operate at a first high wind speed, and the second fan 32 to operate at a second high wind speed, causing the opening degree of the first valve body 41 of the air conditioner indoor unit to be greater than or equal to a first preset opening degree, the opening degree of the second valve body 42 of the air conditioner indoor unit to be greater than or equal to a second preset opening degree, and the operating frequency of the compressor 8 of the air conditioning system to be a preset frequency; when the outdoor environment temperature is less than or equal to the first preset temperature, keeping the rotating speed of the outdoor fan 7, the first fan 31 and the second fan 32 unchanged, keeping the opening degree of the first valve body 41 and the second valve body 42 unchanged, and keeping the operating frequency of the compressor 8 unchanged; wherein the first preset temperature is greater than or equal to 37℃ and less than or equal to 40℃; the rotating 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 rotating speed corresponding to the first high wind speed and the second high wind speed is greater than or equal to 1200r / min and less than or equal to 1350r / min; the first preset opening degree is P1, P1=P 01 + a, P 01 is the opening degree of the first valve body 41 corresponding to the rated cooling capacity of the air conditioning system; the second preset opening degree is P2, P2=P 02 + a, P 02 is the opening degree of the second valve body 42 corresponding to the rated cooling capacity of the air conditioning system, and 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 environment temperature, and T0 is the first preset temperature. In this way, when the outdoor environment temperature is higher than the first preset temperature, it indicates that it is in hot weather conditions, and the control method immediately adjusts the key parameters of the air conditioning system to enhance the refrigeration effect. The outdoor fan 7 operates at a preset high wind speed, which significantly improves the external heat exchange efficiency and is beneficial 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 the indoor heat exchange, and improves the refrigeration efficiency of the air conditioner.

[0135] Specifically, when the outdoor environment temperature is greater than the first preset temperature, the initial rotating speed of the air conditioner indoor fan (the first fan 31 and the second fan 32) operates at the corresponding high wind speed (if the set wind speed is lower than the high wind speed, it operates at the set wind speed), and the outdoor fan 7 operates 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 is not less than P1, P1=P 01 +50% for the first 10 minutes, and F=F0-(T1-40). This ensures that the outdoor pipe temperature does not exceed the over-load shutdown temperature during the start-up process of the whole machine, thereby affecting the refrigeration of the air conditioner.

[0136] Specifically, in the case that the outdoor ambient temperature is greater than the first preset temperature, if the rotation speed corresponding to the set wind level of the outdoor fan 7 is greater than the rotation speed corresponding to the first high wind level, the outdoor fan 7 is caused to operate at the set wind level thereof; if the rotation speed corresponding to the set wind level of the first fan 31 is greater than the rotation speed corresponding to the first high wind level, the first fan 31 is caused to operate at the set wind level thereof; and if the rotation speed corresponding to the set wind level of the second fan 32 is greater than the rotation speed corresponding to the second high wind level, the second fan 32 is caused to operate at the set wind level thereof.

[0137] Specifically, in the case that the outdoor ambient temperature is greater than the first preset temperature, if the first preset opening degree is greater than the maximum opening degree of the first valve body 41, the opening degree of the first valve body 41 is caused to be the maximum opening degree thereof. If the second preset opening degree is greater than the maximum opening degree of the second valve body 42, the opening degree of the second valve body 42 is caused to be the maximum opening degree thereof.

[0138] In an embodiment, before obtaining the activity region where the human body position is located, the control method further comprises: obtaining the indoor ambient temperature; comparing the indoor ambient temperature with the preset indoor temperature; when the difference between the indoor ambient temperature and the preset indoor temperature is less than or equal to the preset difference temperature, causing the human body position detection member 10 of the air conditioner indoor unit to enter the detection state; when the difference between the indoor ambient temperature and the preset indoor temperature is greater than the preset difference temperature, causing the human body position detection member 10 of the air conditioner indoor unit to be in the standby state or the shutdown state; wherein the preset difference temperature is greater than or equal to 1℃ and less than or equal to 3℃. With such a setting, the control method first obtains the indoor ambient temperature and compares it with the preset indoor temperature. Only when the difference between the two is less than or equal to the preset difference temperature, the human body position detection member 10 is activated to enter the detection state. When the difference between the indoor ambient temperature and the preset indoor temperature is greater than the preset difference temperature, the air conditioning system judges that the indoor is still in the early cooling stage, and at this time the human body position detection member 10 is set to be in the standby state or the shutdown state. This means that during the process of high indoor temperature and full cooling of the air conditioning system to approach the preset temperature, the system temporarily does not need to perform human body position detection. This strategy effectively avoids the inaccuracy of human body position detection due to large indoor temperature difference in the early cooling stage, and reduces the energy consumption of the system running the human body position detection member 10 at unnecessary times, achieving more energy-saving operation. Specifically, the preset difference temperature is 2℃.

[0139] It should be noted that the detection state means that the human body position detection member 10 can immediately obtain the human body position. The standby state means that the human body position detection member 10 is powered on but not in the detection state. The shutdown state means that the human body position detection member 10 is in an unpowered state.

[0140] In an embodiment, the air conditioner indoor unit is the air conditioner indoor unit described above, and the air conditioner indoor unit further comprises a first valve body 41 and a second valve body 42. The control method further comprises: obtaining the operating frequency of the compressor 8 of the air conditioning system; in the case that the operating frequency of the compressor 8 reaches the minimum operating frequency, continuously obtaining the refrigerant temperature of the condenser 6 of the air conditioning system; when the refrigerant temperature of the condenser 6 is greater than or equal to the preset outdoor refrigerant temperature, and the refrigerant temperature of the condenser 6 is in a continuous rising state, reducing the rotation speed of the first fan 31 and the rotation speed of the second fan 32 by a preset number of revolutions per minute, and increasing the opening degree of the first valve body 41 of the air conditioner indoor unit and the opening degree of the second valve body 42 of the air conditioner indoor unit by a preset opening degree per minute; when the refrigerant temperature of the condenser 6 is less than the preset outdoor refrigerant temperature or the refrigerant temperature of the condenser 6 is not in a continuous rising state, keeping the rotation speed of the first fan 31 and the rotation speed of the second fan 32 unchanged, and keeping the opening degree of the first valve body 41 and the opening degree of the second valve body 42 unchanged; wherein the preset outdoor refrigerant temperature is greater than or equal to 56℃ and less than or equal to 60℃; the preset number of revolutions is greater than or equal to 8r and less than or equal to 12r; and the preset opening degree is greater than or equal to 1% and less than or equal to 3%. With such a setting, when the air conditioning system operates at the minimum operating frequency of the compressor 8, by monitoring the refrigerant temperature of the condenser 6, if the refrigerant temperature continuously rises and reaches or exceeds the preset outdoor refrigerant temperature, the system will automatically adjust the rotation speed of the first fan 31 and the second fan 32 to be reduced, while gradually increasing the opening degree 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 state, and maintains the stability and reliability of the system. Specifically, the preset outdoor refrigerant temperature is 56℃, the preset number of revolutions is 10r, and the preset opening degree is 2%.

[0141] It should be noted that the refrigerant temperature of the condenser 6 being in a continuous 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 rotation speed, valve body opening degree, air guide part position and the frequency of the compressor 8 corresponding to different active areas are as shown in the following table.
