Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically relating to a heat exchanger assembly and an air conditioner. Background Technology

[0002] Traditional air conditioners have relatively fixed supply and return air vent positions. However, indoor air temperature stratifies along the vertical direction. Warmer air, due to its lower density, tends to accumulate at higher altitudes, while cooler air, due to its higher density, tends to accumulate at lower altitudes. This means that air conditioners with fixed supply and return air positions cannot accommodate various operating conditions. Under certain operating conditions, uneven temperature stratification along the vertical direction (thermal stratification) occurs, preventing optimal energy efficiency and comfort.

[0003] Taking a cabinet air conditioner with top-supply and bottom-return or top-supply and rear-return configurations as an example, the air supply vent is positioned high above the unit. In summer, when cooling, the jet of air quickly reaches the area above where people are active. The high density of the cold air allows it to naturally sink, achieving rapid cooling with minimal draft, balancing temperature reduction and comfort. Simultaneously, because the return air vent is located at the bottom of the unit, the return air temperature is about 2°C lower than that at the upper middle section, resulting in better energy efficiency. However, in winter, when heating, the hot air jet cannot descend from the upper part of the room due to the principle of hot air rising, resulting in a phenomenon of "hot at the top, cold at the bottom." In this case, the return air temperature at the bottom is only about 2°C lower than that at the upper middle section. Compared to the upper middle section, more energy is needed to achieve the same outlet air temperature, resulting in poorer energy efficiency. This type of air conditioner, with its fixed supply and return air positions, fails to simultaneously achieve optimal energy saving and comfort under different cooling / heating conditions. Therefore, the traditional unidirectional airflow circulation method cannot simultaneously meet the needs of energy saving in cooling and heating while maintaining comfort.

[0004] There is an urgent need to transform the air circulation mode from unidirectional circulation to bidirectional reversible circulation. There are two existing methods for reversible air supply air conditioners: one is to set up a reversible axial flow fan and control the forward and reverse rotation of the axial flow fan motor to achieve reversible air supply; the other is to set up a mixed flow fan and achieve reversible air supply through mixed flow fan blades.

[0005] The aforementioned air conditioner exchanges heat with the air in the duct through a heat exchanger assembly. The heat exchanger assembly has two heat exchangers. When the air conditioner is in heating mode, the air in the duct exchanges heat with each heat exchanger of the heat exchanger assembly and is then discharged directly from the air outlet. When there is a temperature difference between the two heat exchangers of the heat exchanger assembly, the temperature of the air outlet after heat exchange between the two heat exchangers is uneven, which affects the user's comfort. Utility Model Content

[0006] Therefore, this utility model provides a heat exchanger assembly and an air conditioner, which can solve the technical problem in the prior art that when the air conditioner is in heating operation and there is a temperature difference between the heat exchangers in the heat exchanger assembly, the outlet air temperature is uneven after heat exchange by each heat exchanger, resulting in poor user comfort.

[0014] And / or, the heat exchanger assembly further includes a drip tray for receiving condensate from both the first heat exchanger and the second heat exchanger.

[0015] In some embodiments, the heat exchanger assembly further includes a temperature detection device for detecting the tube temperature of the first heat exchanger and the tube temperature of the second heat exchanger, respectively.

[0016] In some embodiments, the heat exchanger assembly further includes a drive mechanism through which the flow divider is driven to move.

[0017] In some embodiments, the drive mechanism drives the diverter to move through a transmission mechanism; wherein the transmission mechanism is a rack and pinion mechanism or a crank-connecting rod mechanism.

[0018] This utility model also provides an air conditioner, which includes the heat exchanger assembly described in any one of the above descriptions; wherein the air conditioner has a heating mode, and in the heating mode, the first side of the heat exchanger assembly is the windward side.

[0019] In some embodiments, the air conditioner further includes a casing and an air duct component. The casing has an air duct inside, and the air duct component and the heat exchanger assembly are arranged sequentially within the air duct. The air duct component drives the airflow within the air duct, and the heat exchanger assembly exchanges heat with the airflow through the air duct. The air conditioner also has a cooling mode. In the cooling mode, the first side of the heat exchanger assembly is the leeward side, and the air duct receives air through the lower side of the casing and exits air through the upper side of the casing. In the heating mode, the air duct receives air through the upper side of the casing and exits air through the lower side of the casing.

[0020] The air duct component is located on one side of the heat exchanger assembly; the air duct component is located downstream of the heat exchanger assembly in cooling mode and downstream of the heat exchanger assembly in heating mode.

[0021] In some embodiments, the duct component and the heat exchanger assembly are arranged sequentially from top to bottom within the duct, and the first side of the heat exchanger assembly is the upper side of the heat exchanger assembly.

[0022] In some embodiments, the air duct has a first upper air inlet, a second upper air inlet, and a third upper air inlet on the upper side of the housing; the air duct component is an axially inlet and radially outlet air duct component; the axial direction of the air duct component is arranged horizontally, and the air duct component has a first end and a second end opposite each other in the axial direction; the first end is opposite to a first sidewall of the air duct, and a first air duct section is formed between the two; the second end is opposite to a second sidewall of the air duct, and a second air duct section is formed between the two; the upper end of the first air duct section is opposite to the first upper air inlet, and the upper end of the second air duct section is opposite to the second upper air inlet; the lower ends of both the first and second air duct sections are opposite to the air inlets of the heat exchanger assembly; the air...

The lower end of the first duct section, the lower end of the second duct section, the first top air outlet, and the second top air outlet can all be opened and closed. In the cooling mode, both the first top air outlet and the second top air outlet are closed, and the duct component is switched to top air outlet, allowing air to exit through the third top air outlet from the upper side of the casing. In the heating mode, the duct component is switched to bottom air outlet, and both the first top air outlet and the second top air outlet are open, allowing air to enter through the first top air outlet and the second top air outlet from the upper side of the casing.

[0023] The heat exchanger assembly and air conditioner provided by this utility model have the following beneficial effects:

[0024] When the heat exchanger assembly of this invention is applied to an air conditioner, the first side of the heat exchanger assembly can be configured as the air-facing side during heating operation. Since the flow divider can adjust the airflow into each heat exchanger, when the air conditioner is in heating operation and there is a temperature difference between the heat exchangers, the flow divider can be adjusted to increase the airflow into the high-temperature heat exchanger and decrease the airflow into the low-temperature heat exchanger. This helps to ensure a consistent airflow temperature after heat exchange in each heat exchanger, thereby improving the uniformity of the outlet air temperature and preventing large temperature differences or cold air blowing during heating operation, thus enhancing user comfort and experience.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0039] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0040] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0041] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0042] See also Figure 1-3 As shown, according to an embodiment of the present invention, a heat exchanger assembly 100 is provided, which includes a flow divider 3 and two or more heat exchangers. The flow divider 3 is used to divide the incoming air from the first side 10a of the heat exchanger assembly to each heat exchanger. The flow divider 3 is movable to adjust the airflow flowing into each heat exchanger.

[0043] When the aforementioned heat exchanger assembly 100 is applied to an air conditioner, the first side 10a of the heat exchanger assembly can be configured as the windward side during heating operation. Since the flow divider 3 can adjust the airflow into each heat exchanger, when the air conditioner is in heating operation and there is a temperature difference between the heat exchangers in the heat exchanger assembly 100, the flow divider 3 can be activated to increase the airflow into the high-temperature heat exchanger and decrease the airflow into the low-temperature heat exchanger. This helps to ensure that the airflow temperature is consistent after heat exchange in each heat exchanger, thereby improving the uniformity of the outlet air temperature of each heat exchanger. This avoids large temperature differences in the air blown out during heating operation or the problem of blowing cold air, improving user comfort and experience.

[0044] In some implementations, such as Figure 1-3As shown, there are two heat exchangers, namely a first heat exchanger 1 and a second heat exchanger 2. The first heat exchanger 1 and the second heat exchanger 2 are arranged in a V-shape, forming a first V-shaped opening on one side and a second V-shaped opening on the other side. An air vent 101 is formed between the relatively open ends of the first heat exchanger 1 and the second heat exchanger 2, and this air vent 101 is located on the first side 10a of the aforementioned heat exchanger assembly. The heat exchanger assembly 100 receives the incoming air from the first side 10a through this air vent 101. The aforementioned flow divider 3 is disposed at the air vent 101 and extends from one side 1a of the first heat exchanger 1 and the second heat exchanger 2 to the other side 1b.

[0045] In the above example, since the diverter 3 extends from one side 1a of the first heat exchanger 1 and the second heat exchanger 2 to the other side 1b, the diverter 3 can divide the air outlet 101 into a first air outlet 101a opposite to the first heat exchanger 1 and a second air outlet 101b opposite to the second heat exchanger 2. This facilitates the diverter 3 to divert the incoming air from the first side 10a to the first air outlet 101a and the second air outlet 101b, and guide the diverted air to the first heat exchanger 1 through the first air outlet 101a, and guide the diverted air to the second heat exchanger 2 through the second air outlet 101b. In this way, the diverter 3 can realize the function of diverting the incoming air from the first side 10a of the heat exchanger assembly to each heat exchanger.

[0046] To achieve the function of the aforementioned flow divider 3 in adjusting the airflow into each heat exchanger through movement, in some embodiments, such as Figure 3 As shown, the aforementioned air vent 101 is formed between the first a end 1c of the first heat exchanger 1 and the first b end 1d of the second heat exchanger 2, and the aforementioned diverter 3 is used to move between the first a end 1c and the first b end 1d to move closer to or further away from the first a end 1c.

[0047] In the above example, the first air vent 101a is formed between the diverter 3 and the first a-end 1c, and the second air vent 101b is formed between the diverter 3 and the second a-end. When the diverter 3 moves closer to the first a-end 1c, the diameter of the first air vent 101a decreases, and the diameter of the second air vent 101b increases. This reduces the airflow flowing into the first heat exchanger 1 through the first air vent 101a and increases the airflow flowing into the second heat exchanger 2 through the second air vent 101b. Similarly, when the diverter 3 moves away from the first a-end 1c, the diameter of the first air vent 101a increases, and the diameter of the second air vent 101b decreases. This increases the airflow flowing into the first heat exchanger 1 through the first air vent 101a and decreases the airflow flowing into the second heat exchanger 2 through the second air vent 101b.

[0048] In this invention, the guide member can be located at any position between the aforementioned first a end 1c and first b end 1d, including but not limited to... Figure 5 and Figure 8 Position 1 of the two Figure 6 and Figure 9 Position 2 and Figure 7 and Figure 10 Position 3 of the two.

[0049] In some embodiments, the aforementioned diverter 3 is used to move in a straight line between the first a end 1c and the first b end 1d.

[0050] In some embodiments, the cross-sectional shape of the aforementioned flow guide can be rhomboid. Depending on the application scenario, the cross-sectional shape of the flow guide can be adjusted to various shapes such as rectangle and triangle.

[0051] In some implementations, such as Figure 1-3 As shown, the aforementioned heat exchanger assembly 100 may further include a first fixing frame 4, which is frame-shaped. The open ends of both the first heat exchanger 1 and the second heat exchanger 2 are fixed to the first fixing frame 4, and the frame-shaped opening of the first fixing frame 4 forms the aforementioned air vent 101.

[0052] In the above example, by setting the first fixing frame 4 to fix the open ends of the first heat exchanger 1 and the second heat exchanger 2, it is beneficial to improve the stability of the aforementioned air outlet 101, so that the air coming from the first side 10a of the heat exchanger assembly can be stably introduced from the air outlet 101.

[0053] In some implementations, such as Figure 1-3 As shown, the aforementioned heat exchanger assembly 100 may also include a first cover plate 6 and a second cover plate 7. The first cover plate 6 is used to cover the first V-shaped opening, and the second cover plate 7 is used to cover the second V-shaped opening. This facilitates the air to pass through each heat exchanger for heat exchange and prevents the air from flowing out of the first V-shaped opening and the second V-shaped opening without heat exchange.

[0054] In some implementations, such as Figure 1-3 As shown, the aforementioned heat exchanger assembly 100 may further include a second fixing frame 5, on which the relatively close ends of the first heat exchanger 1 and the second heat exchanger 2 are fixed to the second fixing frame 5, so as to improve the stability of the arrangement structure of the first heat exchanger 1 and the second heat exchanger 2.

[0055] In some implementations, such as Figure 1-3As shown, the aforementioned heat exchanger assembly 100 may further include a drip tray 61 for receiving condensate from both the first heat exchanger 1 and the second heat exchanger 2. The drip tray 61 may be mounted on the aforementioned second mounting bracket 5, with the end of the drip tray 61 positioned close to the opposite end of the first heat exchanger 1 and the second heat exchanger 2, so that when the aforementioned air vent 101 is facing upwards, the drip tray 61 can receive condensate dripping from the first heat exchanger 1 and the second heat exchanger 2.

[0056] In some embodiments, the aforementioned heat exchanger assembly 100 further includes a temperature detection device for detecting the tube temperature of the first heat exchanger 1 and the tube temperature of the second heat exchanger 2. By comparing the tube temperatures of both the first and second heat exchangers 1 and 2, it can be determined which heat exchanger 1 has a higher temperature. This allows for convenient adjustment of the flow divider 3 during air conditioning heating operation, increasing the airflow into the high-temperature heat exchanger and decreasing the airflow into the low-temperature heat exchanger, thereby improving the uniformity of the outlet air temperature of each heat exchanger.

[0057] In some embodiments, the aforementioned temperature detection device includes a first temperature sensor and a second temperature sensor. The temperature detection device detects the tube temperature of the first heat exchanger 1 through the first temperature sensor and the tube temperature of the second heat exchanger 2 through the second temperature sensor. Both the first and second temperature sensors can be tube temperature sensors. This invention can adjust the position of the flow divider 3 in real time by tracking the tube temperatures of both the first heat exchanger 1 and the second heat exchanger 2, thereby achieving the purpose of regulating the temperature consistency of the air outlet 101.

[0058] In some embodiments, the aforementioned heat exchanger assembly 100 may further include a drive mechanism, through which the flow divider 3 is driven to move. By using a drive mechanism to move the flow divider 3, manpower can be saved and automated control can be facilitated.

[0059] In some embodiments, the aforementioned drive mechanism can drive the diverter 3 to move via a transmission mechanism. This transmission mechanism can be a rack and pinion mechanism or a crank-connecting rod mechanism, etc. The drive mechanism may include a motor to drive the transmission mechanism.

[0060] In some implementations, such as Figure 4-10As shown, this utility model also provides an air conditioner, which may include the heat exchanger assembly 100 of any of the above-mentioned components. The air conditioner has a heating mode, in which the first side 10a of the heat exchanger assembly is the windward side. Because the air conditioner uses the aforementioned heat exchanger assembly 100, the flow divider 3 can adjust the airflow into each heat exchanger through movement. When the air conditioner is in heating operation and there is a temperature difference between the heat exchangers of the heat exchanger assembly 100, the flow divider 3 can be moved to increase the airflow into the high-temperature heat exchanger and decrease the airflow into the low-temperature heat exchanger. This helps to ensure that the airflow temperature is consistent after heat exchange in each heat exchanger, thereby improving the uniformity of the outlet air temperature of each heat exchanger and avoiding large temperature differences in the air blown out during heating operation or the problem of blowing cold air, thus improving user comfort and experience.

[0061] In some implementations, the aforementioned air conditioner may be a cabinet air conditioner.

[0062] In some implementations, such as Figure 4-10 As shown, the aforementioned air conditioner also includes a casing 23 and an air duct component 13. The casing 23 has an air duct 22 inside, and the air duct component 13 and the heat exchanger assembly 100 are arranged sequentially within the air duct 22. The air duct component 13 drives the airflow within the air duct 22, and the heat exchanger assembly 100 exchanges heat with the air flowing through the air duct 22. The air conditioner also has a cooling mode. In cooling mode, the first side 10a of the heat exchanger assembly is the leeward side, and the air duct 22 receives air through the lower side of the casing 23 and exits air through the upper side of the casing 23. In heating mode, the air duct 22 receives air through the upper side of the casing 23 and exits air through the lower side of the casing 23. The air duct component 13 is located on one side of the heat exchanger assembly 100. The air duct component 13 is located downstream of the heat exchanger assembly 100 in cooling mode and downstream of the heat exchanger assembly 100 in heating mode.

[0063] In the example above, such as Figure 5-7 As shown, in cooling mode, air enters from the lower side of the casing 23 and exits from the upper side. The air first flows through the heat exchanger assembly 100 for heat exchange, then flows through the air duct component 13 and exits from the upper side of the casing 23. After heat exchange in the heat exchanger assembly 100, the air is thoroughly mixed through the air duct component 13, which helps to ensure a uniform air outlet temperature at the upper air vent 140. Therefore, there is no problem of inconsistent air outlet temperature. The actual function of the air distribution component 3 is to ensure uniform airflow distribution on both sides of the air duct component 13, preventing noise caused by uneven airflow distribution on both sides of the double suction blades, thus affecting air conditioning comfort. Figure 8-10As shown, in heating mode, air enters from the upper side of the casing 23 and exits from the lower side of the casing 23. The air first flows through the air duct component 13, then undergoes heat exchange through the heat exchanger assembly 100, and is discharged from the upper side of the casing 23. When the temperature difference between the first heat exchanger 1 and the second heat exchanger 2 exceeds a preset value, such as 3°C, the position of the flow divider 3 can be adjusted, for example, by moving it to... Figure 8 Position 1 or Figure 10 Position 3 in the middle is intended to increase the airflow distribution on the heat exchanger side with higher temperature, so that the airflow temperature is consistent after heat exchange between the two heat exchangers, avoiding large temperature differences in the air blown out by the air conditioner or the problem of blowing cold air, and improving the user experience.

[0064] In a specific application example, such as Figure 4-10 As shown, the aforementioned air duct component 13 and heat exchanger assembly 100 are arranged sequentially from top to bottom within the air duct 22, and the first side 10a of the heat exchanger assembly is the upper side of the heat exchanger assembly 100.

[0065] In the above example, by arranging the air duct component 13 and the heat exchanger assembly 100 sequentially from top to bottom within the air duct 22, the space in the height direction within the casing 23 can be fully utilized.

[0066] In some implementations, such as Figure 5-10As shown, the air duct 22 has a first upper air inlet 141, a second upper air inlet 142, and a third upper air inlet 143 on the upper side of the housing 23. The aforementioned air duct component 13 can be an axially inlet and radially outlet air duct component 13. The axial direction of the air duct component 13 is arranged horizontally, and the air duct component 13 has a first end 131 and a second end 132 opposite to each other in the axial direction. The first end 131 is opposite to the first sidewall 211 of the air duct 22, and a first air duct section 20 is formed between the two. The second end 132 is opposite to the second sidewall 212 of the air duct 22, and a second air duct section 21 is formed between the two. The upper end of the first air duct section 20 is opposite to the first upper air inlet 141, so that the upper end of the first air duct section 20 is connected to the first upper air inlet 141. The upper end of the second air duct section 21 is opposite to the second upper air inlet 142, so that the upper end of the second air duct section 21 is connected to the second upper air inlet 142. The lower ends of both the first air duct section 20 and the second air duct section 21 are opposite to the air outlet 101 of the heat exchanger assembly, so that the lower ends of both the first air duct section 20 and the second air duct section 21 are connected to the air outlet 101 of the heat exchanger assembly. The air duct component 13 can be switched to upper air outlet or lower air outlet. When the air duct component 13 is switched to upper air outlet, its air outlet is opposite to the third upper air outlet 143, and when the air duct component 13 is switched to lower air outlet, its air outlet is opposite to the air outlet 101 of the heat exchanger assembly. The lower ends of the first air duct section 20, the lower ends of the second air duct section 21, the first upper air outlet 141, and the second upper air outlet 142 can all be opened and closed. In cooling mode, the first upper air outlet 141 and the second upper air outlet 142 are both closed, and the air duct component 13 is switched to upper air outlet, so that the upper side of the casing 23 is vented through the third upper air outlet 143. In heating mode, the air duct component 13 switches to bottom air outlet, and both the first upper air inlet 141 and the second upper air inlet 142 are opened, allowing air to enter the upper side of the casing 23 through the first upper air inlet 141 and the second upper air inlet 142.

[0067] The first upwind vent 141 can be opened and closed via the first baffle 16. The second upwind vent 142 can be opened and closed via the second baffle 17. The lower end of the first air duct section 20 can be opened and closed via the third baffle 18, and the lower end of the second air duct section 21 can be opened and closed via the fourth baffle 19.

[0068] The aforementioned air duct component 13 may include an internal air duct, fan blades, and a motor, etc. The air duct component 13 may be a centrifugal fan or a double-suction air duct component, etc. The specific structure of the air duct component 13 is existing technology and will not be described in detail here.

[0069] In the above example, the reversible air supply of the air conditioner can be realized through the above structural settings. When the air conditioner is in heating operation and there is a temperature difference between the heat exchangers of the heat exchanger assembly 100, the uniformity of the air outlet temperature of each heat exchanger can be improved by the movable diverter 3, so as to avoid the problem of large temperature difference of the air blown out during the heating operation of the air conditioner or the problem of blowing cold air, thereby improving the user's comfort and experience.

[0070] In some implementations, such as Figure 5-10 As shown, the lower side of the aforementioned housing 23 has a first lower air vent 711 and a second lower air vent 712. The first lower air vent 711 can be located on the front side of the housing and is normally open. The second lower air vent 712 is located on the rear side of the housing and can be opened and closed. In cooling mode, the second lower air vent 712 is open, allowing air to enter the lower side of the housing 23 simultaneously through the first lower air vent 711 and the second lower air vent 712. In heating mode, the second lower air vent 712 is closed, allowing air to exit the lower side of the housing 23 through the first lower air vent 711.

[0071] For ease of understanding, the cooling and heating modes of the air conditioner will be explained in detail below. It should be noted that this utility model includes, but is not limited to, these two operating modes: cooling and heating. The positions of the aforementioned baffles and the position of the air distribution component 3 will differ in different operating modes.

[0072] Cooling mode: such as Figure 5-7 As shown, when the air conditioner is in cooling mode, the user can select the single top air outlet mode. In this mode, the first and second baffles 16 and 17 are closed, while the third and fourth baffles 18 and 19 are open, and the air duct component 13 switches to top air outlet. At this time, the air conditioner draws air in from the bottom and exits it from the top. The air passes through the first heat exchanger 1 and the second heat exchanger 2 for heat exchange before being blown out from the third top air outlet 143 through the air outlet of the air duct component 13. The flow divider 3 on the heat exchanger assembly 100 is in the center position 2 by default. Since the air is heated by the heat exchanger assembly 100 before being blown out by the air duct component 13 (e.g., a dual-suction air duct component), there is no issue of inconsistent air outlet temperature. At this time, the actual function of the diverter 3 is to ensure that the airflow on both sides of the air duct component 13 is evenly distributed. By adjusting the position of the diverter 3, the airflow after heat exchange by the heat exchanger assembly 100 can flow evenly into both sides of the air duct component 13, preventing the problem of loud noise caused by uneven airflow distribution on both sides of the air duct component 13, thereby affecting the comfort of air conditioning.

[0073] Heating mode: such as Figure 8-10As shown, when the air conditioner is in heating mode, the user can select the single downward air outlet mode. In this mode, the first and second baffles 16 and 17 are open, while the third and fourth baffles 18 and 19 are closed, and the air duct component 13 switches to downward air outlet. At this time, the air conditioner draws in air from the top and exits it from the bottom. The airflow enters from the first and second upper air inlets 141 and 142 at the top of the unit, passes through the air duct component 13 (e.g., a dual-suction air duct system), and exits from the bottom side of the air duct component 13. It then undergoes heat exchange with the first heat exchanger 1 and the second heat exchanger 2 before being blown out from the bottom side of the casing 23. Specifically, the airflow is drawn in from both sides of the air duct component 13 axially and then blown out from the bottom side. After being split by the diverter 3, it undergoes heat exchange with the first heat exchanger 1 and the second heat exchanger 2. The default position of the diverter 3 at this time is... Figure 9 In the central position 2, when the temperature difference detected by the temperature sensors (e.g., pipe temperature bulbs) on the first heat exchanger 1 and the second heat exchanger 2 is greater than a preset temperature (e.g., 3°C), the flow divider 3 adjusts its position to the center position via the drive mechanism. Figure 8 Middle position 1 or Figure 10 Position 3 in the middle is intended to increase the airflow distribution on the heat exchanger on the side with higher temperature, so that the airflow temperature is consistent after heat exchange between the two heat exchangers, avoiding large temperature differences in the air blown out by the air conditioner or the problem of blowing cold air, and improving the user experience.

[0074] To facilitate understanding, the airflow regulation principle of the diverter 3 will be further explained below. For example, Figure 3 As shown, the flow divider 3 divides the air vent 101 of the heat exchanger assembly into a first air vent 101a and a second air vent 101b. The flow divider 3 adjusts the size of both the first air vent 101a and the second air vent 101b by moving, thereby adjusting the airflow of both air vents 101a and 101b. When the temperature of the first heat exchanger 1 on the left is high, the first air vent 101a is enlarged to allow it to exchange heat with the first heat exchanger 1 with a larger airflow; when the temperature of the second heat exchanger 2 on the right is high, the second air vent 101b is enlarged to allow it to exchange heat with the second heat exchanger 2 with a larger airflow.

[0075] The aforementioned air conditioner is a reversible air supply and return air air conditioner, such as... Figure 4 As shown, the aforementioned casing includes a front panel 70, a left side panel component 9, a right side panel component 10, a chassis component 15, a top cover component 11, and an air inlet panel 8. An air outlet frame component 12 is provided between the aforementioned air duct component 13 and the top cover component 11, and a lower air outlet channel component 14 is provided between the heat exchanger assembly 100 and the chassis component 15. The aforementioned first fixing bracket 4, first cover plate 6, second cover plate 7, and second fixing bracket 5 fix the first heat exchanger 1 and the second heat exchanger 2 and are fixedly connected to the air inlet panel 8 of the casing.

[0076] The first heat exchanger 1 and the second heat exchanger 2 are fixed together with the air inlet panel 8 by screws after being fixed by the first fixing bracket 4, the first cover plate 6, the second cover plate 7 and the second fixing bracket 5, and cooperate with the front panel 70 to form a closed structure, thereby separating the air inlet end from the air outlet end.

[0077] The heat exchanger assembly 100 of this invention is based on a reversible air-flow air conditioner. The heat exchanger assembly 100 and the air duct component 13 are combined to form an upward and downward layout, achieving upward air intake and downward air outlet for heating, and downward air intake and upward air outlet for cooling. A movable diverter 3 is provided at the upper end of the heat exchanger assembly 100. Air blown from the air duct 22 is diverted by the diverter 3, heat-exchanged by the heat exchanger assembly 100, and then blown out from the air outlet. By adjusting the position of the diverter 3, the airflow through the two heat exchangers can be adjusted to achieve consistent outlet air temperature. This ensures consistent outlet air temperature in different air conditioning operating modes, preventing cold air blowing or uneven outlet air temperature from affecting the user experience and causing after-sales complaints.
