Description

Technical Field

[0001] The present application relates to but is not limited to the technical field of air conditioners, and specifically refers to a window air conditioner and a control method and a control device thereof. Background Art

[0002] At present, the working noise of window air conditioners is relatively high. In addition, the functions of window air conditioners are relatively simple, and they can generally only process indoor air. This affects the market competitiveness of window air conditioners and is not conducive to the promotion and use of window air conditioners. Summary of the invention

[0003] The technical problem to be solved by the present application is to provide a window air conditioner and a control method and a control device thereof, which can reduce the operating noise of the window air conditioner and enrich the functions of the window air conditioner, which is beneficial to improving the market competitiveness of the window air conditioner and facilitating the promotion and use of the window air conditioner.

[0005] The window air conditioner provided in the embodiment of the present application has the indoor unit and the outdoor unit separated, thereby realizing the separation of the indoor unit and the outdoor unit of the window air conditioner. Therefore, the noise generated by the compressor and the outdoor fan of the outdoor unit will not be transmitted to the indoor side through the machine itself and heard by the user, thereby reducing the working noise felt by the user and improving the user's comfort. In addition, the outdoor unit and the indoor unit are separated, so it is only necessary to install the indoor unit in the window, and the outdoor unit can be installed in other locations outside the window, such as on the outdoor wall, or on the outdoor ground or other installation carriers, without being installed in the window. Compared with the existing integrated window air conditioner, this solution is equivalent to reducing the thickness of the window air conditioner, realizing the thinning design of the window air conditioner, which is beneficial to improving the aesthetics of the window air conditioner and reducing the difficulty of installing the window air conditioner.

[0007] In addition, the air outlet of the indoor unit is not a single air outlet, but includes a first air outlet and a second air outlet, and the first air outlet and the second air outlet can be opened one by one, or opened together, or closed together. The first air outlet and the second air outlet can be opened one by one, so as to facilitate directional air outlet according to user needs. The first air outlet and the second air outlet are opened together, so that air can be supplied over a large range, which is convenient for rapid adjustment of indoor temperature. The first air outlet and the second air outlet are closed together, and the return air outlet can be used as an air outlet, so that natural ventilation can be achieved, achieving the effect of ventilation without opening the window.

[0058] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0059] Research has found that the reason why window air conditioners are noisy is that the indoor and outdoor units are integrated together, which causes the noise of the compressor and outdoor fan to be transmitted to the indoor side through the machine itself, causing the user to hear a loud working noise. The reason why window air conditioners have relatively simple functions is that existing window air conditioners can only perform internal circulation, that is, they can only suck indoor air into the casing for processing (such as heating, cooling, etc.) and then discharge it into the room.

[0060] To this end, the embodiment of the present application provides a window air conditioner, including: an indoor unit and an outdoor unit (not shown in the figure). The outdoor unit is separately arranged from the indoor unit and connected to the indoor unit. The outdoor unit may include a compressor, an outdoor fan and other structures.

[0061] like Figures 1 to 22 As shown, the indoor unit includes: a housing 1, a valve assembly, an indoor fan and an outdoor heat exchanger. The indoor unit may also include a water pump, a water receiving pan and other structures.

[0062] Among them, Figures 1 to 3 As shown, the housing 1 is provided with a fresh air inlet 121, a return air inlet 113, a first air outlet 111 and a second air outlet 112. The return air inlet 113, the first air outlet 111 and the second air outlet 112 are all connected to the indoor space. The fresh air inlet 121 is connected to the outdoor space. The return air inlet 113 is located between the first air outlet 111 and the second air outlet 112. A return air grille 16 may be provided at the return air inlet 113, as shown in FIG. Figure 1 As shown. A wind guide blade may be provided at the fresh air outlet 121. A first wind guide plate 23 and a second wind guide plate 24 may be provided at the first air outlet 111 and the second air outlet 112, respectively. Fig.12The first air guide plate 23 and the second air guide plate 24 have the function of guiding the wind, and can also control the opening and closing of the first air outlet 111 and the second air outlet 112.

[0063] Furthermore, the return air port 113 is configured to be able to communicate with the first air outlet 111 to form a first internal circulation air duct. Figure 8 , Fig.16 and Fig.21 The return air port 113 is configured to be connected to the second air outlet 112 to form a second internal circulation air duct. Figure 8 , Fig.16 and Fig.21 The fresh air outlet 121 is configured to be connected to the first air outlet 111 to form a first external circulation air duct. Fig. 9 , Fig.17 , Fig.18 and Fig. 22 The fresh air outlet 121 is configured to be connected to the second air outlet 112 to form a second external circulation air duct. Fig. 9 , Fig.17 , Fig.18 and Fig. 22 The fresh air outlet 121 is also configured to be able to communicate with the return air outlet 113 to form a natural ventilation duct, such as Fig.11 shown.

[0064] The valve assembly is configured to control the opening and closing of the first internal circulation air duct, the second internal circulation air duct, the first external circulation air duct, the second external circulation air duct and the natural ventilation air duct.

[0065] The indoor fan is disposed in the casing 1 , and is configured to drive the air in the casing 1 to flow toward the first air outlet 111 and / or the second air outlet 112 .

[0066] The indoor heat exchanger is disposed in the casing 1 , and is configured to perform heat exchange with the airflow flowing toward the first air outlet 111 and / or the second air outlet 112 .

[0067] The window air conditioner provided in the embodiment of the present application has the indoor unit and the outdoor unit separated, thereby realizing the separation of the indoor unit and the outdoor unit of the window air conditioner. Therefore, the noise generated by the compressor and the outdoor fan of the outdoor unit will not be transmitted to the indoor side through the machine itself and heard by the user, thereby reducing the working noise felt by the user and improving the user's comfort. In addition, the outdoor unit and the indoor unit are separated, so it is only necessary to install the indoor unit in the window, and the outdoor unit can be installed in other locations outside the window, such as on the outdoor wall, or on the outdoor ground or other installation carriers, without being installed in the window. Compared with the existing integrated window air conditioner, this solution is equivalent to reducing the thickness of the window air conditioner, realizing the thinning design of the window air conditioner, which is beneficial to improving the aesthetics of the window air conditioner and reducing the difficulty of installing the window air conditioner.

[0068] In addition, the indoor unit is provided with a fresh air outlet 121 and a corresponding valve assembly, so that the window air conditioner has a plurality of air ducts that can be selected to be turned on and off. The window air conditioner can operate in the internal circulation mode, the external circulation mode, the internal and external circulation mode, and the natural ventilation mode. The internal circulation mode, the external circulation mode, and the internal and external circulation mode can all be used in combination with the cooling, heating, dehumidification, and air supply functions, thereby greatly enriching the functions of the window air conditioner and being able to provide users with a variety of air solutions, which is convenient for users to adjust and choose freely according to their needs, thereby helping to improve the market competitiveness of the window air conditioner and promoting the use of the window air conditioner.

[0069] In addition, the air outlet of the indoor unit is not a single air outlet, but includes a first air outlet 111 and a second air outlet 112, and the first air outlet 111 and the second air outlet 112 can be opened one by one, or opened together, or closed together. The first air outlet 111 and the second air outlet 112 can be opened one by one, so as to facilitate directional air outlet according to user needs. The first air outlet 111 and the second air outlet 112 are opened together, so that air can be supplied over a large range, which is convenient for rapid adjustment of indoor temperature. The first air outlet 111 and the second air outlet 112 are closed together, and the return air outlet 113 can be used as an air outlet, so that natural ventilation can be achieved, and the effect of ventilation without opening the window is achieved. Therefore, this further enriches the functions of the window air conditioner and is conducive to further improving the user experience.

[0070] Moreover, under the condition of the same air volume, compared with setting one air outlet, setting two air outlets in combination with two air ducts is beneficial to reducing the flow area of ​​the air duct, thereby reducing the thickness of the indoor unit, which is beneficial to the thinning design of the window air conditioner.

[0071] For example, when outdoor fresh air is not needed (for example, when the outdoor air quality is poor or the indoor air quality is good), the window air conditioner can operate in the internal circulation mode, such as Figure 8 , Fig.16 and Fig.21 As shown, the valve assembly can conduct at least one of the first internal circulation air duct and the second internal circulation air duct, and start the indoor fan accordingly, so that the air in the casing 1 flows to the first air outlet 111 and / or the second air outlet 112. When only the first internal circulation air duct is conducted, the indoor fan drives the air in the casing 1 to flow only to the first air outlet 111. When only the second internal circulation air duct is conducted, the indoor fan drives the air in the casing 1 to flow only to the second air outlet 112. When both the first internal circulation air duct and the second internal circulation air duct are conducted, the indoor fan drives the air in the casing 1 to flow to the first air outlet 111 and the second air outlet 112.

[0072] When outdoor fresh air is needed (for example, when the outdoor air quality is good and the indoor air quality needs to be improved), the window air conditioner can operate in the external circulation mode, such as Fig. 9 , Fig.17 , Fig.18 and Fig. 22 As shown, the valve assembly can conduct at least one of the first external circulation air duct and the second external circulation air duct, and start the indoor fan accordingly, so that the air in the casing 1 flows to the first air outlet 111 and / or the second air outlet 112. When only the first external circulation air duct is conducted, the indoor fan drives the air in the casing 1 to flow only to the first air outlet 111. When only the second external circulation air duct is conducted, the indoor fan drives the air in the casing 1 to flow only to the second air outlet 112. When both the first external circulation air duct and the second external circulation air duct are conducted, the indoor fan drives the air in the casing 1 to flow to the first air outlet 111 and the second air outlet 112.

[0073] Alternatively, when outdoor fresh air is needed (for example, when the outdoor air quality is good and the indoor air quality needs to be improved), the window air conditioner can also operate in the internal and external circulation mode, such as Fig.10 , Fig.19 , Fig. 20 As shown, the valve assembly can conduct at least one of the first inner circulation air duct and the second inner circulation air duct, and conduct at least one of the first outer circulation air duct and the second outer circulation air duct, and start the indoor fan accordingly, so that the air in the casing 1 flows to the first air outlet 111 and / or the second air outlet 112. In this way, the indoor air and the outdoor fresh air can be mixed and heat-exchanged in the casing 1, and the cold / heat of the indoor air can be fully utilized to achieve the effect of energy saving, and then heat exchange is performed through the indoor heat exchanger to realize the functions of fresh air ventilation and internal cooling / heating. Among them, when only the first inner circulation air duct and the first outer circulation air duct are conducted, the indoor fan drives the air in the casing 1 to flow only to the first air outlet 111. When only the second inner circulation air duct and the second outer circulation air duct are conducted, the indoor fan drives the air in the casing 1 to flow only to the second air outlet 112. When both the first air outlet 111 and the second air outlet 112 need to discharge air, for example, the first internal circulation air duct, the second internal circulation air duct, the first external circulation air duct and the second external circulation air duct are all connected, the indoor fan drives the air in the casing 1 to flow to the first air outlet 111 and the second air outlet 112.

[0074] For seasons when air conditioning is not needed to regulate indoor air, window air conditioners can operate in natural ventilation mode, such as Fig.11 As shown, the valve assembly conducts the natural ventilation duct, and the indoor fan does not need to be turned on. Outdoor air can enter the natural ventilation duct through the fresh air inlet 121 and enter the room through the return air inlet 113. Indoor air can enter the natural ventilation duct through the return air inlet 113 and flow to the outdoors through the fresh air inlet 121, thereby realizing natural convection between indoor and outdoor air and achieving the effect of ventilation without opening windows.

[0075] In some exemplary embodiments, the housing 1 includes a panel 11 and a back panel 12 which are arranged relatively spaced apart in the thickness direction of the indoor unit. Figures 1 to 3 The first air outlet 111, the return air outlet 113, and the second air outlet 112 are provided on the panel 11 and are spaced apart along the height direction (ie, the up-down direction) of the panel 11. Figure 2 and Fig.14 As shown. The fresh air outlet 121 is provided on the back plate 12. Figure 3 and Fig.13 As shown. The first air outlet 111 is an upper air outlet, which can be set at the upper end of the panel 11. The second air outlet 112 is a lower air outlet, which can be set at the lower end of the panel 11. The return air outlet 113 is set in the middle area in the height direction of the panel 11. The fresh air outlet 121 is set in the middle area in the height direction of the back panel 12.

[0076] In this way, the first air outlet 111, the return air outlet 113, and the second air outlet 112 face the indoor side and communicate with the indoor space. The fresh air outlet 121 faces the outdoor side and communicates with the outdoor space, and the introduction of outdoor fresh air can be achieved without additionally setting up a fresh air duct.

[0077] When the first air outlet 111 is opened, the second air outlet 112 is closed, and the indoor fan is turned on accordingly, the indoor unit discharges air upward. When the second air outlet 112 is opened, the first air outlet 111 is closed, and the indoor fan is turned on accordingly, the indoor unit discharges air downward. When both the first air outlet 111 and the second air outlet 112 are opened, and the indoor fan is turned on accordingly, the indoor unit discharges air upward and downward. Therefore, the window air conditioner of the embodiment of the present application can have a variety of air outlet modes, which is convenient for users to choose according to their needs.

[0078] The housing 1 may be in a flat rectangular parallelepiped structure, with a thickness direction consistent with the thickness direction of the window, a length direction consistent with the height direction, and a width direction extending in the horizontal direction.

[0079] In some exemplary embodiments, the housing 1 is provided with a first air outlet duct 13, an intermediate air duct 15 and a second air outlet duct 14 which are arranged in sequence and connected to each other along a first direction. Figure 1 The fresh air inlet 121 and the return air inlet 113 are both connected to the middle air duct 15. The first air outlet 111 and the second air outlet 112 are respectively connected to the first air outlet duct 13 and the second air outlet duct 14. The first direction can be the height direction of the housing 1, that is, the up and down direction.

[0080] The return air port 113 is arranged to communicate with the first air outlet 111 through the intermediate air duct 15 and the first air outlet duct 13 .

[0081] The return air port 113 is configured to communicate with the second air outlet 112 through the intermediate air duct 15 and the second air outlet duct 14 .

[0082] The fresh air port 121 is arranged to communicate with the first air outlet 111 through the intermediate air duct 15 and the first air outlet duct 13 .

[0083] The fresh air inlet 121 is arranged to communicate with the second air outlet 112 through the middle air duct 15 and the second air outlet duct 14 .

[0084] The fresh air inlet 121 is arranged to communicate with the return air inlet 113 through the intermediate air duct 15 .

[0085] In this way, the first internal circulation air duct and the first external circulation air duct share most of the air ducts, and the first internal circulation air duct and the second external circulation air duct share most of the air ducts. By controlling the opening and closing of the fresh air inlet 121 and the return air inlet 113, the opening and closing of the first air outlet 111 and the second air outlet 112, and the opening and closing of the indoor fan, the switching of the internal circulation mode, the external circulation mode, the internal and external circulation mode, and the natural ventilation mode can be realized. This is conducive to simplifying the structure of the indoor unit, thereby helping to reduce production costs.

[0086] When the fresh air inlet 121 is closed, the return air inlet 113 is opened, the first air outlet 111 and / or the second air outlet 112 is opened and the indoor fan is started, the first internal circulation air duct and / or the second internal circulation air duct can be opened to operate the internal circulation mode.

[0087] When the fresh air inlet 121 is opened, the return air inlet 113 is closed, the first air outlet 111 and / or the second air outlet 112 is opened and the indoor fan is started, the first external circulation air duct and / or the second external circulation air duct can be opened to operate the external circulation mode.

[0088] When the fresh air inlet 121 is opened, the return air inlet 113 is opened, the first air outlet 111 and / or the second air outlet 112 is opened and the indoor fan is started, the first internal circulation air duct and / or the second internal circulation air duct can be opened, and the first external circulation air duct and / or the second external circulation air duct can be opened to operate the internal and external circulation mode.

[0089] When the fresh air inlet 121 is opened, the return air inlet 113 is opened, the first air outlet 111 and the second air outlet 112 are closed, and the indoor fan is not started, the natural ventilation duct can be opened and the natural ventilation mode can be operated.

[0090] In some exemplary embodiments, the indoor fan includes a first fan 31 and a second fan 32. Figure 1 and Fig.12 As shown, the first fan 31 is disposed in the first air outlet duct 13 , and the second fan 32 is disposed in the second air outlet duct 14 .

[0091] In this way, the first fan 31 is used to drive the air in the housing 1 to flow toward the first air outlet 111. The second fan 32 is used to drive the air in the housing 1 to flow toward the second air outlet 112. The first fan 31 and the second fan 32 do not affect each other, and can be started one by one or started together or shut down together as needed to achieve switching of different air outlet modes.

[0092] Of course, the indoor fan may also be a fan, which is arranged in the middle air duct 15 and can discharge air to the first air outlet 111 or the second air outlet 112 .

[0093] In some exemplary embodiments, the first fan 31 and the second fan 32 are cross-flow fans. Fig.12 As shown, the rotation axis of the crossflow fan extends along the width direction of the housing 1. This is conducive to increasing the air volume of the window air conditioner without causing the window air conditioner to be too large, and is conducive to reducing the thickness of the window air conditioner, thereby realizing a thinning design of the window air conditioner; and the operation noise of the crossflow fan is relatively small, which is conducive to reducing the working noise of the window air conditioner.

[0094] In some exemplary embodiments, the valve assembly includes: a fresh air valve 21 and a return air valve 22, such as Figure 2 and Figure 3 The fresh air valve 21 is disposed at the fresh air inlet 121 and is configured to control the opening and closing of the fresh air inlet 121. The return air valve 22 is disposed at the return air inlet 113 and is configured to control the opening and closing of the return air inlet 113.

[0095] By controlling the opening and closing of the fresh air valve 21, the opening and closing of the fresh air outlet 121 can be controlled. By controlling the opening and closing of the return air valve 22, the opening and closing of the return air outlet 113 can be controlled. By controlling the opening and closing of the first air guide plate 23 and the second air guide plate 24, the opening and closing of the first air outlet 111 and the second air outlet 112 can be controlled. In this way, by controlling the opening and closing of the fresh air valve 21 and the return air valve 22, and the opening and closing of the first air guide plate 23, the second air guide plate 24, and the indoor fan, the switching of different circulation modes of the window air conditioner can be realized.

[0096] When the fresh air valve 21 is closed, the return air valve 22 is opened, the first air guide plate 23 and / or the second air guide plate 24 are opened, and the indoor fan is started, the first internal circulation air duct and / or the second internal circulation air duct can be opened to operate the internal circulation mode, such as Figure 8 and Fig.16 shown.

[0097] When the fresh air valve 21 is opened, the return air valve 22 is closed, the first air guide plate 23 and / or the second air guide plate 24 are opened, and the indoor fan is started, the first external circulation air duct and / or the second external circulation air duct can be connected to run the external circulation mode, such as Fig. 9 , Fig.17 and Fig.18shown.

[0098] When the fresh air valve 21 is opened, the return air valve 22 is opened, the first air guide plate 23 and / or the second air guide plate 24 are opened, and the indoor fan is started, the first internal circulation air duct and / or the second internal circulation air duct can be connected, and the first external circulation air duct and / or the second external circulation air duct can be connected to operate the internal and external circulation mode, such as Fig.10 , Fig.19 and Fig. 20 shown.

[0099] When the fresh air valve 21 is opened, the return air valve 22 is opened, the first air guide plate 23 and the second air guide plate 24 are closed, and the indoor fan is not started, the natural ventilation duct can be opened to operate the natural ventilation mode, such as Fig.11 shown.

[0100] In some exemplary embodiments, Figures 1 to 11 As shown, the fresh air inlet 121 is connected to the end of the middle air duct 15 facing the outside, and the return air inlet 113 is connected to the end of the middle air duct 15 facing the inside. Figures 1 to 3 shown.

[0101] The indoor heat exchanger includes a first heat exchanger 41 and a second heat exchanger 42 which are separately arranged. Figure 1 The first heat exchanger 41 is located in the first air outlet duct 13 , and the second heat exchanger 42 is located in the second air outlet duct 14 .

[0102] The first heat exchanger 41 is used to exchange heat with the airflow flowing to the first air outlet 111. The second heat exchanger 42 is used to exchange heat with the airflow flowing to the second air outlet 112. In order to increase the heat exchange area of ​​the first heat exchanger 41 and the second heat exchanger 42, the height of the middle air duct 15 can be appropriately smaller, the height of the first air outlet duct 13 and the second air outlet duct 14 can be appropriately larger, and the first heat exchanger 41 can be tilted in the first air outlet duct 13, and the second heat exchanger 42 can be tilted in the second air outlet duct 14.

[0103] The fresh air inlet 121 can be directly connected to the return air inlet 113 through the intermediate air duct 15. The areas of the fresh air inlet 121 and the return air inlet 113 can be reasonably set as needed without affecting each other.

[0104] The area of ​​the return air vent 113 can be substantially the same as the cross-sectional size of the intermediate air duct 15. The return air vent 113 can also include a plurality of air inlets arranged at intervals. The shape of the air inlet can be circular, square, or other shapes. Compared with the area of ​​the return air vent 113, the area of ​​the fresh air vent 121 can be appropriately reduced. For example, the return air vent 113 can include three circular air inlets, such as Figure 2 and Figure 3As shown, the return air valve 22 includes three valves. The fresh air inlet 121 may include a circular air inlet, and the fresh air valve 21 includes a valve. The valve can be switched between the closed position and the open position by rotating, sliding, etc.

[0105] In some embodiments, a filter 5 is provided at the fresh air outlet 121 and / or the return air outlet 113. Figure 1 The filter 5 can filter and purify the air entering the housing 1, so that the air flowing into the indoor space is purified.

[0106] The filter screen 5 can be configured as a detachable structure, so that it can be removed and cleaned as needed. The filter screen 5 at the return air outlet 113 can be directly removed and replaced indoors.

[0107] In addition to the filter 5, other purification modules for purifying the air can also be arranged in the middle air duct 15. In this way, even in the natural ventilation mode, the air entering the room can be purified.

[0108] Of course, the position of the filter 5 is not limited to the fresh air outlet 121 and the return air outlet 113. For example, the filter 5 can also be arranged at the connecting position between the middle air duct 15 and the first air outlet channel, and at the connecting position between the middle air duct 15 and the second air outlet channel.

[0109] In other exemplary embodiments, Figures 12 to 22 As shown, the indoor heat exchanger is an integrated heat exchanger 43 , and the integrated heat exchanger 43 is arranged in the middle air duct 15 .

[0110] In this way, the first internal circulation air duct, the second internal circulation air duct, the first external circulation air duct, and the second external circulation air duct share an integrated heat exchanger 43, which is conducive to fully utilizing the space in the housing 1, thereby increasing the heat exchange area of ​​the indoor heat exchanger to improve the heat exchange effect of the window air conditioner, and the structure is compact and efficient, and no additional air duct is required. In addition, compared with installing two heat exchangers separately, an integrated heat exchanger 43 is also easier to install.

[0111] Compared with the aforementioned embodiment, the height of the middle air duct 15 of this embodiment can be appropriately increased, while the height of the first air outlet duct 13 and the second air outlet duct 14 can be appropriately reduced to increase the area of ​​the indoor heat exchanger and reduce the air duct length, thereby improving the heat exchange effect.

[0112] In some exemplary embodiments, the intermediate air duct 15 includes a fresh air channel 153, an upstream channel 151 and a downstream channel 152. Fig.15 and Fig.19The upstream channel 151 is connected to the return air port 113. The downstream channel 152 is connected to the first air outlet duct 13 and the second air outlet duct 14. The fresh air port 121 is connected to the upstream channel 151 through the fresh air channel 153.

[0113] The integrated heat exchanger 43 is located between the upstream channel 151 and the downstream channel 152. A filter screen 5 is also provided between the integrated heat exchanger 43 and the return air outlet 113. The filter screen 5 and the integrated heat exchanger 43 separate and connect the upstream channel 151 and the downstream channel 152. The fresh air channel 153 can be surrounded by a partition, and the cross-sectional shape of the partition can be adapted to the fresh air outlet 121. The side plate of the integrated heat exchanger 43 can be connected to the partition.

[0114] In this way, indoor air and outdoor air can be filtered through the same filter 5, and the filter 5 can be configured as a detachable structure so as to be disassembled and cleaned indoors through the return air port 113.

[0115] When running in inner loop mode, Fig.16 As shown, the indoor air enters the upstream channel 151 through the return air port 113 , and then flows through the filter 5 , the indoor heat exchanger, and the downstream air duct in sequence to enter the first air outlet duct 13 and / or the second air outlet duct 14 .

[0116] When running in external loop mode, Fig.17 and Fig.18 As shown, outdoor fresh air enters the fresh air channel 153 through the fresh air outlet 121, and then flows through the upstream channel 151, the filter 5, the indoor heat exchanger, and the downstream air duct in sequence to enter the first air outlet duct 13 and / or the second air outlet duct 14.

[0117] When running the internal and external circulation mode, such as Fig.19 and Fig. 20 As shown, indoor air enters the upstream channel 151 through the return air outlet 113, and outdoor fresh air enters the upstream channel 151 through the fresh air outlet 121 and the fresh air channel 153. After the indoor air and the outdoor fresh air are mixed in the upstream channel 151, they flow through the filter 5, the indoor heat exchanger, and the downstream air duct in sequence to enter the first air outlet duct 13 and / or the second air outlet duct 14.

[0118] When running in natural ventilation mode, please refer to Fig.11 As shown, outdoor fresh air enters the fresh air channel 153 through the fresh air outlet 121, and then enters the room through the upstream channel 151 and the return air outlet 113 in sequence. The indoor air enters the upstream channel 151 through the return air outlet 113, and then is discharged to the outdoors through the fresh air channel 153 and the fresh air outlet 121.

[0119] In some exemplary embodiments, two ends of the downstream channel 152 in the first direction (up and down direction) are respectively connected to the first air outlet duct 13 and the second air outlet duct 14, such as Fig.15 shown.

[0120] The number of fresh air passages 153 is two. Fig.12 and Fig.13 As shown, two fresh air passages 153 are respectively arranged on both sides of the second direction of the downstream air passage, and the second direction is perpendicular to the first direction. The first direction is the height direction of the housing 1, that is, the up-down direction, and the second direction is the width direction of the housing 1.

[0121] This is conducive to expanding the area of ​​the fresh air outlet 121, thereby facilitating increasing the fresh air flow rate. The shape of the fresh air outlet 121 can be, but is not limited to, a rectangle. The fresh air outlet 121 can also include a plurality of air inlets arranged at intervals.
