[0037] like Figure 1 and Figure 2 As shown, the first embodiment of this application discloses an air conditioner with dual air ducts (hereinafter referred to as the air conditioner), including a housing 100 and a fan assembly 200. The housing 100 has a first air outlet 111, a second air outlet 121, and a first return air outlet 112. The first air outlet 111 and the first return air outlet 112 are connected to form a first air duct 101 capable of supplying air to a first space, and the second air outlet 121 and the first return air outlet 112 are connected to form a second air duct 102 capable of supplying air to a second space. The fan assembly 200 includes a first fan 210 and a second fan 220, with the first fan 210 disposed within the first air duct 101 and the second fan 220 disposed within the second air duct 102.

[0038] In this embodiment, the air conditioner has two air ducts: a first air duct 101 and a second air duct 102. Under the action of the first fan 210, air enters the first air duct 101 through the first return air inlet 112 and is blown into the first space through the first air outlet 111. Under the action of the second fan 220, air enters the second air duct 102 through the second return air inlet 122 and is blown into the second space through the second air outlet 121. Thus, a single air conditioner can supply air to two spaces separately or simultaneously, thereby adjusting the air parameters of both spaces to meet the user's needs.

[0039] Optionally, such as Figure 1 As shown, the housing 100 includes a first side plate 110, a second side plate 120, a bottom plate 130, and a top plate 140. The first side plate 110 and the second side plate 120 are arranged opposite to each other. The bottom plate 130 is connected to the lower part of the first side plate 110 and the second side plate 120, and the top plate 140 is connected to the upper part of the first side plate 110 and the second side plate 120. Furthermore, a first air outlet 111 is formed on the first side plate 110, a second air outlet 121 is formed on the second side plate 120, and a first return air outlet 112 is formed on the bottom plate 130.

[0040] Optionally, the first space and the second space are connected. For example, the first space is the living room, and the second space is the dining room. The first air outlet 111 faces the living room, and the second air outlet 121 faces the dining room.

[0041] Optionally, the plane containing the first air outlet 111 and the plane containing the first return air outlet 112 are perpendicular to each other. In this way, the air enters the first air duct 101 from the first return air outlet 112 and then turns at 90° to flow towards the first air outlet 111, thus optimizing the airflow path.

[0042] Optionally, the plane of the second air outlet 121 is perpendicular to the plane of the first return air outlet 112. In this way, the air enters the second air duct 102 from the first return air outlet 112 and then turns at 90° to flow towards the second air outlet 121, thus optimizing the airflow path.

[0043] Optionally, such as Figure 1 As shown, a first damper 113 is provided at the first return air inlet 112. The first damper 113 is rotatably configured to cover or avoid the first return air inlet 112. In this way, when the first damper 113 covers the first return air inlet 112, air cannot enter the housing 100. When the first damper 113 avoids the first return air inlet 112, air can enter the housing 100 from the first return air inlet 112.

[0044] Optionally, such as Figure 2As shown, the air conditioner also includes a heat exchange assembly 300, which includes a first evaporator 310 and a second evaporator 320. The first evaporator 310 is disposed within the first air duct 101, and the second evaporator 320 is disposed within the second air duct 102. Furthermore, the first evaporator 310 and the second evaporator 320 are connected in parallel to the refrigerant circulation system of the air conditioner. In this way, the two evaporators can exchange heat with the air in the first air duct 101 and the second air duct 102 respectively, thereby regulating the temperature of the first space and the second space respectively.

[0045] Optionally, a first throttling device is provided on the inlet side of the first evaporator 310, and the air conditioner also includes a first temperature sensor and a controller. The first temperature sensor is used to detect a first temperature at the first air outlet 111. The controller is electrically connected to the first throttling device, the first temperature sensor, and the first fan 210. The controller is used to control the first throttling device to throttle and the first fan 210 to deliver air when the first temperature difference between the first temperature and the preset temperature is greater than or equal to a preset value.

[0046] In this embodiment, through precise temperature monitoring and regulation, the system can ensure that the temperature of the first space remains within a preset range, avoiding excessive temperature fluctuations that could cause discomfort to the occupants. For example, the preset value is 0.5℃. When the first temperature difference is greater than or equal to 0.5℃, the controller controls the first throttling device to throttle the airflow and the first fan 210 to blow air. At this time, the air in the first air duct 101 exchanges heat with the first evaporator 310 and is then blown into the first space. When the first temperature difference is less than 0.5℃, the controller controls the first throttling device to close and the first fan 210 to stop. In this way, energy efficiency is improved while maintaining the temperature of the first space.

[0047] Optionally, a second throttling device is provided on the inlet side of the second evaporator 320, and the air conditioner also includes a second temperature sensor and a controller. The second temperature sensor is used to detect the second temperature at the second air outlet 121. The controller is electrically connected to the second throttling device, the second temperature sensor, and the second fan 220. The controller is used to control the second throttling device to throttle and the second fan 220 to deliver air when the second temperature difference between the second temperature and the preset temperature is greater than or equal to a preset value.

[0048] In this embodiment, through precise temperature monitoring and regulation, the system can ensure that the temperature of the second space remains within a preset range, avoiding excessive temperature fluctuations that could cause discomfort to the occupants. For example, the preset value is 0.5℃. When the second temperature difference is greater than or equal to 0.5℃, the controller controls the second throttling device to throttle the airflow and the second fan 220 to blow air. At this time, the air in the second air duct 102 exchanges heat with the second evaporator 320 and is then blown into the second space. When the second temperature difference is less than 0.5℃, the controller controls the second throttling device to close and the second fan 220 to stop. In this way, energy efficiency is improved while maintaining the temperature of the second space.

[0049] Optionally, the first evaporator 310 is arranged perpendicular to the base plate 130. This optimizes the component layout inside the housing 100.

[0050] Alternatively, the second evaporator 320 is arranged perpendicular to the base plate 130. This optimizes the component layout inside the housing 100.

[0051] Optionally, the first return air vent 112 is located on the base plate 130, between the first evaporator 310 and the second evaporator 320. Thus, after air enters the casing 100 through the first return air vent 112, it enters the first air duct 101 if the first fan 210 is started, and the second air duct 102 if the second fan 220 is started. If both the first fan 210 and the second fan 220 are started simultaneously, they enter the first air duct 101 and the second air duct 102 respectively.

[0052] like Figure 3 and Figure 4 As shown, the second embodiment of this application discloses an air conditioner, including a housing 100 and a fan assembly 200. The housing 100 has a first air outlet 111, a second air outlet 121, a first return air outlet 112, and a second return air outlet 122. The first air outlet 111 and the first return air outlet 112 are connected to form a first air duct 101, and the second air outlet 121 and the first return air outlet 112 are connected to form a second air duct 102. The first air outlet 111 and the second return air outlet 122 are connected to form a third air duct 103 connected to the first air duct 101, and the second air outlet 121 and the second return air outlet 122 are connected to form a fourth air duct 104 connected to the second air duct 102. The fan assembly 200 includes a first fan 210 and a second fan 220. The first fan 210 is disposed within the first air duct 101, and the second fan 220 is disposed within the second air duct 102. The purification component 400 is located at the second return air inlet 122 and is used to purify the air flowing through it.

[0053] In this embodiment, the air conditioner has four air ducts: a first air duct 101, a second air duct 102, a third air duct 103, and a fourth air duct 104. Under the action of the first fan 210, air enters the first air duct 101 through the first return air inlet 112, and / or, air enters the third air duct 103 through the second return air inlet 122 and then merges back into the first air duct 101, finally being blown into the first space from the first air outlet 111. Under the action of the second fan 220, air enters the second air duct 102 through the second return air inlet 122, and / or, air enters the fourth air duct 104 through the second return air inlet 122 and then merges back into the second air duct 102, finally being blown into the second space from the second air outlet 121. Thus, a single air conditioner can supply air to two spaces separately or simultaneously, thereby adjusting the air parameters of the two spaces to meet the user's needs. Furthermore, the purification component 400 can purify the air flowing through the third air duct 103 and the fourth air duct 104, thereby improving air quality.

[0054] Optionally, such as Figure 4 As shown, the purification assembly 400 includes a first purification section 410, a second purification section 420, and a third purification section 430. The first purification section 410 is disposed inside the second return air vent 122 and is spaced apart from it. A first side of the second purification section 420 is connected to a first side of the first purification section 410, and a second side of the second purification section 420 is inclined towards the second return air vent 122. A first side of the third purification section 430 is connected to a second side of the first purification section 410, and a second side of the third purification section 430 is inclined towards the second return air vent 122. Thus, the purification assembly 400 is composed of three interconnected parts forming a bow-like shape, with the inner side of the bow facing the second return air vent 122.

[0055] Optionally, the first purification section 410 is parallel to the second return air vent 122. This facilitates sufficient contact between the air from the second return air vent 122 and the first purification section 410.

[0056] Optionally, the second side of the second purification section 420 contacts the inner periphery of the second return air inlet 122. This helps to enhance the sealing between the second purification section 420 and the second return air inlet 122, preventing unpurified air from entering the air duct.

[0057] Optionally, the second side of the third purification section 430 contacts the inner periphery of the second return air inlet 122. This helps to enhance the sealing between the third purification section 430 and the second return air inlet 122, preventing unpurified air from entering the air duct.

[0058] Optionally, such as Figure 4As shown, the air conditioner also includes a heat exchange assembly 300, which includes a first evaporator 310. The first evaporator 310 is disposed within a first air duct 101. A first purification section 410 is located upstream of the first evaporator 310, and a third air duct 103 can be connected to the first air duct 101 through the first purification section 410; a second purification section 420 is arranged side by side with the first evaporator 310, and the third air duct 103 can also be connected to the first air duct 101 through the second purification section 420.

[0059] In this embodiment, after entering the third air duct 103 from the second return air inlet 122, the air has two flow paths. The first path is through the first purification section 410 to the first air duct 101, and the second path is through the second purification section 420 to the first air duct 101. Since the second purification section 420 is arranged side by side with the first evaporator 310, the air does not undergo heat exchange when flowing along the second path, and this part of the air mixes with the heat-exchanged air in the first air duct 101. In this way, the mixed air blown out from the first air outlet 111 reduces the temperature difference between the outlet air temperature and the indoor temperature, making the user feel more comfortable.

[0060] Optionally, such as Figure 4 As shown, the air conditioner also includes a heat exchange assembly 300, which includes a second evaporator 320. The second evaporator 320 is disposed within the second air duct 102. A first purification section 410 is located upstream of the second evaporator 320, and a fourth air duct 104 can be connected to the second air duct 102 through the first purification section 410; a third purification section 430 is arranged side by side with the second evaporator 320, and the fourth air duct 104 can also be connected to the second air duct 102 through the third purification section 430.

[0061] In this embodiment, after entering the fourth air duct 104 from the second return air inlet 122, the air has two flow paths. The first path is through the first purification section 410 to the second air duct 102, and the second path is through the third purification section 430 to the first air duct 101. Since the third purification section 430 is arranged side by side with the second evaporator 320, the air does not undergo heat exchange when flowing along the second path, and this part of the air mixes with the heat-exchanged air in the second air duct 102. In this way, the mixed air blown out from the second air outlet 121 reduces the temperature difference between the outlet air temperature and the indoor temperature, making the user feel more comfortable.

[0062] Optionally, such as Figure 3As shown, the housing 100 includes a first side plate 110, a second side plate 120, a bottom plate 130, and a top plate 140. The first side plate 110 and the second side plate 120 are arranged opposite to each other. The bottom plate 130 is connected to the lower part of the first side plate 110 and the second side plate 120, and the top plate 140 is connected to the upper part of the first side plate 110 and the second side plate 120. A first air outlet 111 is located on the first side plate 110, and a second air outlet 121 is located on the second side plate 120. A first return air outlet 112 is located on the bottom plate 130, and a second return air outlet 122 is located on the top plate 140, with the first return air outlet 112 and the second return air outlet 122 arranged opposite to each other.

[0063] Optionally, the first space and the second space are connected. For example, the first space is the living room, and the second space is the dining room. The first air outlet 111 faces the living room, and the second air outlet 121 faces the dining room.

[0064] Optionally, such as Figure 3 As shown, a first damper 113 is provided at the first return air inlet 112, and the first damper 113 is rotatably configured to cover or avoid the first return air inlet 112. A second damper 123 is provided at the second return air inlet 122, and the second damper 123 is rotatably configured to cover or avoid the second return air inlet 122. In this way, the opening and closing status of the corresponding return air inlets can be controlled by the two dampers.

[0065] Optionally, the air conditioner has a first mode, which corresponds to the first damper 113 being closed and the second damper 123 being open. In this way, air can only enter the housing 100 from the second return air inlet 122, and the air flows to the first air duct 101 and / or the second air duct 102 after purification.

[0066] Optionally, the air conditioner has a second mode, with the first mode corresponding to the first damper 113 being open and the second damper 123 being closed. In this way, air can only enter the housing 100 from the first return air inlet 112, and the air flows directly to the first air duct 101 and / or the second air duct 102 without being purified.

[0067] Optionally, the air conditioner has a third mode, with the first mode corresponding to the opening of the first damper 113 and the opening of the second damper 123. In this way, air simultaneously enters the housing 100 from the first return air inlet 112 and the second return air inlet 122 for mixing, and the mixed air flows to the first air duct 101 and / or the second air duct 102.

[0068] like Figures 5 to 7As shown, the third embodiment of this application discloses an air conditioner, including a housing 100 and a fan assembly 200. The housing 100 has a first air outlet 111, a second air outlet 121, and a first return air outlet 112. The first return air outlet 112 is connected to the first air outlet 111 to form a first air duct 101, and the first return air outlet 112 is connected to the second air outlet 121 to form a second air duct 102. The fan assembly 200 includes a first fan 210 and a second fan 220. The first fan 210 is disposed within the first air duct 101, and the second fan 220 is disposed within the second air duct 102. Furthermore, the first fan 210 and / or the second fan 220 are rotatably mounted to adjust the airflow direction.

[0069] In this embodiment, the air conditioner has two air ducts, namely a first air duct 101 and a second air duct 102. Under the action of the first fan 210, air enters the first air duct 101 through the first return air inlet 112 and is blown into the first space through the first air outlet 111. Under the action of the second fan 220, air enters the second air duct 102 through the second return air inlet 122 and is blown into the second space through the second air outlet 121. Thus, a single air conditioner can supply air to two spaces separately or simultaneously, thereby adjusting the air parameters of the two spaces to meet the user's needs. Furthermore, when the first fan 210 is rotatable, the airflow direction of the first air outlet 111 can be adjusted. When the second fan 220 is rotatable, the airflow direction of the second air outlet 121 can be adjusted.

[0070] Optionally, such as Figure 6 As shown, the first fan 210 and the second fan 220 have the same structure. The first fan 210 includes a volute 211 and a first motor 213. A rotating bracket 212 is provided on the first side of the volute 211. The drive shaft of the first motor 213 is connected to the rotating bracket 212 and is used to drive the volute 211 to rotate. In this way, the first motor 213 can drive the rotating bracket 212 to rotate, and the rotating bracket 212 drives the volute 211 to rotate. When the volute 211 rotates, the air outlet direction of the volute 211 is adjusted.

[0071] Optionally, the first fan 210 also includes an impeller 214 and a second motor 215. The impeller 214 is disposed inside the volute 211, and the drive shaft of the second motor 215 is connected to the impeller 214 to drive the impeller 214 to rotate.

[0072] In this embodiment, the rotation axis of the rotating support 212 coincides with the rotation axis of the impeller 214. This ensures that the rotation of the volute 211 does not affect the rotation of the impeller 214, and a fixed gap is maintained between the inner wall of the volute 211 and the impeller 214.

[0073] Optionally, the first motor 213 and / or the second motor 215 are fixed to the top plate 140 of the housing 100. In this way, the first motor 213 and / or the second motor 215 are mounted and fixed through the top plate 140.

[0074] Optionally, such as Figure 7 As shown, the housing 100 includes a first side plate 110 and a bottom plate 130. A first air outlet 111 is formed on the first side plate 110. The bottom plate 130 is connected to the lower part of the first side plate 110, and the bottom plate 130 has a first clearance opening 131. The first clearance opening 131 and the first air outlet 111 are connected to form a first notch 133. When the volute 211 of the first fan 210 rotates, its air outlet direction can swing within the first notch 133. In this way, by combining the first air outlet 111 and the first clearance opening 131 to form the first notch 133, the rotation space of the volute 211 is expanded, thereby increasing the adjustment range of the air outlet direction and making the air outlet of the first fan 210 more flexible.

[0075] Optionally, the first air outlet 111 faces horizontally, the first fan 210 has a first position, and the first position corresponds to the outlet of the volute 211 being directly opposite the first air outlet 111, such as... Figure 5 As shown in Figure (a). Thus, when the first fan 210 rotates to the first position, the first fan 210 blows air in a horizontal direction.

[0076] Optionally, the first clearance opening 131 faces vertically, and the first fan 210 has a second position, wherein the second position corresponds to the outlet of the volute 211 being directly opposite the first clearance opening 131, such as... Figure 5 As shown in Figure (c). Thus, when the first fan 210 rotates to the second position, the first fan 210 blows air vertically downwards.

[0077] Optionally, such as Figure 7 As shown, the housing 100 also includes a second side plate 120. The second side plate 120 is arranged opposite to the first side plate 110, and a second air outlet 121 is formed in the second side plate 120. The bottom plate 130 also has a second clearance opening 132, and the second clearance opening 132 is connected to the second air outlet 121 to form a second notch 134. Furthermore, when the volute 211 of the second fan 220 rotates, its air outlet direction can swing within the second notch 134. In this way, by combining the second air outlet 121 and the second clearance opening 132 to form the second notch 134, the rotation space of the volute 211 is expanded, thereby increasing the adjustment range of the air outlet direction and making the air outlet of the second fan 220 more flexible.

[0078] Optionally, the second air outlet 121 faces horizontally, and the second fan 220 has a first position, wherein the first position corresponds to the outlet of the volute 211 being directly opposite the second air outlet 121, such as... Figure 5As shown in Figure (a). Thus, when the second fan 220 rotates to the first position, the second fan 220 blows air in a horizontal direction.

[0079] Optionally, the second clearance opening 132 faces vertically, the second fan 220 has a second position, and the second position corresponds to the outlet of the volute 211 being directly opposite the second clearance opening 132, such as... Figure 5 As shown in Figure (c). Thus, when the second fan 220 rotates to the second position, the second fan 220 blows air vertically downwards.

[0080] Optionally, the first space and the second space are connected. For example, the first space is the living room, and the second space is the dining room. The first air outlet 111 faces the living room, and the second air outlet 121 faces the dining room.

[0081] Optionally, when the air conditioner is cooling, the first fan 210 and the second fan 220 rotate to their corresponding first positions, thereby blowing cold air horizontally. When the air conditioner is heating, the first fan 210 and the second fan 220 rotate to their corresponding second positions, thereby blowing hot air downwards. Furthermore, the user can control the first fan 210 and the second fan 220 to swing to any position within the corresponding notch according to their airflow needs, such as... Figure 5 The tilt position shown in Figure (b).

[0082] Optionally, the first return air vent 112 is located between the first clearance vent 131 and the second clearance vent 132.

[0083] Optionally, the first fan 210 also includes a mounting plate 216. The outlet of the volute 211 is fixed to the mounting plate 216, which is located at the first air outlet 111. Furthermore, when the volute 211 rotates, it drives the mounting plate 216 to rotate synchronously. In this way, while the mounting plate 216 rotates synchronously with the volute 211, it also serves as a fixed support structure for the volute 211, ensuring the stability of the volute 211 during rotation.

[0084] Optionally, the second fan 220 also includes a mounting plate 216. The outlet of the volute 211 is fixed to the mounting plate 216, which is located at the second air outlet 121.

[0085] The first, second, and third embodiments described above belong to the same model. Unless otherwise specified, the three embodiments and their features can be combined. For example, in the third embodiment, a second return air vent 122 is provided on the top plate 140 of the housing 100, and a second damper 123 and a purification component 400 are provided at the second return air vent 122.

[0086] like Figure 8 and Figure 9As shown, the fourth embodiment of this application discloses an air conditioner, including a housing 100 and a heat exchange assembly 300. The housing 100 includes a first side plate 110 and a second side plate 120 opposite to each other. The first side plate 110 has a first air outlet 111 and a second air return outlet 122. The second side plate 120 has a first air return outlet 112 and a second air outlet 121. The first air return outlet 112 and the first air outlet 111 are connected to form a first air duct 101, and the second air return outlet 122 and the second air outlet 121 are connected to form a second air duct 102. The heat exchange assembly 300 is disposed within the housing 100 and includes a first portion 301 and a second portion 302; wherein the first portion 301 is located within the first air duct 101, and the second portion 302 is located within the second air duct 102.

[0087] In this embodiment, the air conditioner has two air ducts, namely a first air duct 101 and a second air duct 102, and a single heat exchange component 300 simultaneously meets the heat exchange requirements of both air ducts. Air enters the first air duct 101 through the first return air inlet 112, exchanges heat with the first portion 301, and is finally blown into the first space from the first air outlet 111. Air enters the second air duct 102 through the second return air inlet 122, exchanges heat with the second portion 302, and is finally blown into the second space from the second air outlet 121. Thus, a single air conditioner can supply air to both spaces separately or simultaneously, thereby adjusting the air parameters in both spaces to meet the user's needs.

[0088] Optionally, the first space and the second space are connected. For example, the first space is the living room, and the second space is the dining room. The first air outlet 111 faces the living room, and the second air outlet 121 faces the dining room.

[0089] Optionally, such as Figure 9 As shown, the housing 100 is provided with a first partition 150. The first partition 150 is a plate shared by the first air duct 101 and the second air duct 102, and the first partition 150 divides the heat exchange assembly 300 into a first part 301 and a second part 302.

[0090] In this embodiment, the first partition 150 is arranged as a common plate along the extension direction of the first air duct 101. The first plate surface of the first partition 150 is located inside the first air duct 101, and the second plate surface of the first partition 150 is located inside the second air duct 102. Furthermore, the first partition 150 divides the heat exchange assembly 300 into a first part 301 and a second part 302, effectively regulating the airflow through the heat exchange assembly 300 and preventing mutual interference between the airflows of the first air duct 101 and the second air duct 102.

[0091] Optionally, the heat exchange assembly 300 has a first side facing the first air outlet 111 and a second side facing the second air outlet 121. The first partition 150 includes a first plate segment 151 and a second plate segment 152. The first plate segment 151 is connected to the first side, and the second plate segment 152 is connected to the second side. Thus, the first plate segment 151 supports the first side, and the second plate segment 152 supports the second side.

[0092] Optionally, the air conditioner also includes a fan assembly 200, which includes a first fan 210 and a second fan 220. The first fan 210 is disposed within a first air duct 101, and its outlet faces a first air outlet 111. The second fan 220 is disposed within a second air duct 102, and its outlet faces a second air outlet 121. The first fan 210 and the second fan 220 are respectively responsible for the airflow circulation in the first air duct 101 and the second air duct 102, achieving independent control of the two air ducts. This facilitates adjusting the temperature of different spaces according to actual needs, improving the flexibility and adaptability of the air conditioner.

[0093] Optionally, such as Figure 9 As shown, the first fan 210 and the second fan 220 are located on the same side of the heat exchange assembly 300, and the first fan 210 and the second fan 220 are arranged side by side. This makes the internal structure of the air conditioner more compact and helps to reduce the volume of the casing 100.

[0094] Optionally, the axis of the volute 211 of the first fan 210 coincides with the axis of the volute 211 of the second fan 220.

[0095] Optionally, a second partition 160 is provided inside the housing 100. The second partition 160 serves as a plate shared by the first air duct 101 and the second air duct 102, and the second partition 160 is disposed between the first fan 210 and the second fan 220.

[0096] In this embodiment, the second partition 160 is arranged as a common plate along the extending direction of the first air duct 101. The first side of the second partition 160 is located inside the first air duct 101, and the second side of the second partition 160 is located inside the second air duct 102. Furthermore, the second partition 160, positioned between the first fan 210 and the second fan 220, effectively manages the airflow passing through the two fans, preventing mutual interference between the airflows in the first air duct 101 and the second air duct 102.

[0097] Optionally, the outlet of the first fan 210 is mounted on the first fixed plate 221, and the outlet of the second fan 220 is mounted on the second fixed plate 222. Furthermore, the side of the second partition 160 facing the first air outlet 111 is connected to the first fixed plate 221, and the side of the second partition 160 facing the second air outlet 121 is connected to the second fixed plate 222. In this way, both sides of the second partition 160 are connected to the first fixed plate 221 and the second fixed plate 222 respectively, improving structural stability.

[0098] Optionally, the air conditioner also includes a first temperature sensor and a controller. The first temperature sensor is used to detect a first temperature at the first air outlet 111. The controller is electrically connected to the first temperature sensor and the first fan 210. The controller is used to: control the first fan 210 to deliver air at a first speed when the first temperature difference between the first temperature and a preset temperature is greater than or equal to a preset value; and control the first fan 210 to deliver air at a second speed when the temperature difference is less than the preset value; wherein the second speed is less than the first speed.

[0099] In this embodiment, through precise temperature monitoring and regulation, the system can ensure that the temperature of the first space remains within a preset range, avoiding excessive temperature fluctuations that could cause discomfort to the occupants. For example, the preset value is 0.5℃. When the first temperature difference is greater than or equal to 0.5℃, the controller controls the first fan 210 to operate at a faster first speed. At this time, the air in the first air duct 101 exchanges heat with the first section 301 and is then blown into the first space, thereby quickly reducing the first temperature difference. When the first temperature difference is less than 0.5℃, the controller controls the first fan 210 to operate at a slower second speed. In this way, energy efficiency is improved while maintaining the temperature of the second space.

[0100] Optionally, the air conditioner also includes a second temperature sensor and a controller. The second temperature sensor is used to detect a second temperature at the second air outlet 121. The controller is electrically connected to the second temperature sensor and the second fan 220. The controller is used to: control the second fan 220 to deliver air at a first speed when the second temperature difference between the second temperature and the preset temperature is greater than or equal to a preset value; and control the second fan 220 to deliver air at a second speed when the temperature difference is less than the preset value; wherein the second speed is less than the first speed.

[0101] In this embodiment, through precise temperature monitoring and regulation, the system can ensure that the temperature of the second space remains within a preset range, avoiding excessive temperature fluctuations that could cause discomfort to the occupants. For example, the preset value is 0.5℃. When the second temperature difference is greater than or equal to 0.5℃, the controller controls the second fan 220 to operate at a faster first speed. At this time, the air in the second air duct 102 exchanges heat with the second section 302 and is then blown into the second space, thereby quickly reducing the second temperature difference. When the second temperature difference is less than 0.5℃, the controller controls the second fan 220 to operate at a slower second speed. In this way, energy efficiency is improved while maintaining the temperature of the second space.

[0102] Optionally, a third throttling device is provided on the inlet side of the heat exchange component 300. The controller is further configured to: control the third throttling device to throttle at a first opening degree when the first temperature difference or the second temperature difference is greater than or equal to a preset value; and control the third throttling device to throttle at a second opening degree when the temperature difference is less than the preset value; wherein the second opening degree is less than the first opening degree.

[0103] In this embodiment, the controller adjusts the opening of the third throttling device according to the magnitude of the first or second temperature difference, thus flexibly controlling the refrigerant flow rate entering the heat exchange component 300. When the temperature difference is large, the third throttling device throttles at a larger first opening, allowing more refrigerant to enter the heat exchange component 300 for rapid temperature regulation. Conversely, when the temperature difference is small, it throttles at a smaller second opening, reducing the refrigerant flow rate. This dynamic adjustment of the refrigerant flow rate based on the temperature difference significantly improves the energy efficiency of the air conditioner.
