[0077] A data center can be used to deliver, accelerate, present, compute, and store data information on a network infrastructure. With the rapid development of information communication technology industry, the heat generated during the operation of the data center is higher and higher, and the requirement for heat dissipation of the data center is also higher and higher.

[0078] Figure 1 A schematic diagram of a data center is provided for an embodiment of the present application. In the figure, the thick dashed arrow represents the flow direction of indoor wind, and the thin dashed arrow represents the flow direction of outdoor wind.

[0079] As shown in Figure 1 , the data center includes a machine room 10 and a plurality of electronic devices arranged in the machine room 10. Any electronic device can include, but is not limited to, a server, a power distribution box, etc. The electronic devices generate heat during operation, causing the temperature in the machine room 10 to be relatively high.

[0080] To achieve heat dissipation of the data center, the data center further includes an air conditioner 20, which can be used to cool the air in the machine room 10, so that the electronic devices in the machine room 10 can be cooled by cooling the air in the machine room 10.

[0081] In the related art, the refrigeration effect of the air conditioner is poor. As the power consumption of the data center continues to increase, the heat dissipation demand of the data center also increases, and the air conditioner in the related art is difficult to meet the heat dissipation demand of the data center.

[0082] Figure 2 This is a top view schematic diagram of an air conditioner provided in an embodiment of this application. Figure 3 for Figure 2 The diagram provided shows a view from one side of the first end wall of the air conditioner. Figure 4 for Figure 2 The diagram provided shows a view of one side of the second end wall of the air conditioner. In the diagram, the x-direction is the length direction of the casing 100, the y-direction is the width direction of the casing 100, and the z-direction is the height direction of the casing 100.

[0083] Based on this, such as Figures 2-4 As shown in this embodiment, the air conditioner 20 includes a casing 100, which can be a cuboid structure. The casing 100 includes a first side wall 110, a second side wall 120, a first end wall 140, a second end wall 150, a top wall 130, and a bottom wall 160. The first side wall 110 and the second side wall 120 are located on both sides of the width direction of the casing 100, the first end wall 140 and the second end wall 150 are located on both sides of the length direction of the casing 100, and the top wall 130 and the bottom wall 160 are located on both sides of the height direction of the casing 100. The top wall 130 is located at the top of the casing 100, and the bottom wall 160 is located at the bottom of the casing 100, that is, the top wall 130 is above the bottom wall 160. The first side wall 110, the second side wall 120, the first end wall 140, the second end wall 150, the top wall 130, and the bottom wall 160 are joined together to form the outer wall of the casing 100. An air duct 200 is provided between the first side wall 110, the second side wall 120, the first end wall 140, the second end wall 150, the top wall 130, and the bottom wall 160.

[0084] The air duct 200 is provided with a partition 170, which extends along the length of the chassis 100. The partition 170 divides the air duct 200 into an outdoor air duct 210 located between the first side wall 110 and the partition 170, and an indoor air duct 220 located between the second side wall 120 and the partition 170. The outdoor air duct 210 and the indoor air duct 220 are arranged along the width of the chassis 100.

[0085] Outdoor air duct 210 is used to supply outdoor airflow, and indoor air duct 220 is used to supply indoor airflow.

[0086] Outdoor air refers to the air outside the computer room 10, while indoor air refers to the air inside the computer room 10. Outdoor air duct 210 and indoor air duct 220 are isolated from each other.

[0087] At least one of the first side wall 110 and the top wall 130 is provided with an outdoor air inlet, and at least one of the first side wall 110 and the top wall 130 is provided with an outdoor air outlet. The outdoor air inlet and the outdoor air outlet are both in communication with the outdoor air duct 210. The outdoor air flows into the outdoor air duct 210 through the outdoor air inlet and flows back to the environment outside the machine room 10 from the outdoor air duct 210 through the outdoor air outlet.

[0088] At least one of the second side wall 120 and the top wall 130 is provided with an indoor air inlet, and at least one of the second side wall 120 and the top wall 130 is provided with an indoor air outlet. The indoor air inlet and the indoor air outlet are both in communication with the indoor air duct 220. The indoor air flows into the indoor air duct 220 through the indoor air inlet and flows back to the machine room 10 from the indoor air duct 220 through the indoor air outlet.

[0089] The air conditioner 20 further comprises an evaporator 310, a condenser 320, a refrigerant driving component 330 and a throttling component, which are used to form a refrigerant circulation loop. The refrigerant driving component 330 is used to drive the refrigerant to flow in the refrigerant circulation loop. The refrigerant evaporates in the evaporator 310 to absorb heat and condenses in the condenser 320 to release heat.

[0090] The evaporator 310 is arranged in the indoor air duct 220 and is used to cool the indoor air flowing through the indoor air duct 220. Specifically, the refrigerant evaporates in the evaporator 310 to absorb heat in the indoor air. The condenser 320 is arranged in the outdoor air duct 210, and the outdoor air flowing through the outdoor air duct 210 is used to cool the condenser 320. Specifically, the heat released by the refrigerant condensing in the condenser 320 is taken away by the outdoor air.

[0091] In this way, compared with the scheme in which the indoor air duct 220 and the outdoor air duct 210 are arranged along the length direction of the cabinet 100, the outdoor air duct 210 and the indoor air duct 220 are formed along the width direction of the cabinet 100 by the separation of the partition plate 170 extending along the length direction of the cabinet 100. Therefore, the space on the cabinet 100 for arranging the outdoor air inlet, the outdoor air outlet, the indoor air inlet and the indoor air outlet is larger, which is beneficial to arranging the outdoor air inlet, the outdoor air outlet, the indoor air inlet and the indoor air outlet with larger flow area.

[0092] The flow area of the outdoor air inlet and the outdoor air outlet is large, so that the flow of outdoor air through the outdoor air duct 210 is large, which is beneficial to take away the heat released by the refrigerant in the condenser 320, and the outdoor air can provide a larger cooling capacity. The flow area of the indoor air inlet and the indoor air outlet is large, so that the flow of indoor air through the indoor air duct 220 is large, which is beneficial to improve the cooling efficiency of the evaporator 310 on the indoor air. In summary, in the embodiment of the present application, the air conditioner 20 has a good cooling effect and can better cool the air in the machine room 10.

[0093] In addition, the flow area of the outdoor air inlet, the outdoor air outlet, the indoor air inlet and the indoor air outlet is large, so that the air resistance at the outdoor air inlet, the outdoor air outlet, the indoor air inlet and the indoor air outlet is small, which is beneficial to improve the energy efficiency of the air conditioner 20. The outdoor air duct 210 and the indoor air duct 220 are arranged along the width direction of the cabinet 100, so that the flow path of the outdoor air between the outdoor air inlet and the outdoor air outlet is short, and the flow path of the indoor air between the indoor air inlet and the indoor air outlet is short, so that the air resistance in the outdoor air duct 210 and the indoor air duct 220 is small, which is also beneficial to improve the energy efficiency of the air conditioner 20.

[0094] In addition, the evaporator 310 and the condenser 320 are arranged in the cabinet 100, and the air conditioner 20 is an all-in-one machine, which is convenient to install in the machine room 10 and is convenient to realize on-site rapid delivery.

[0095] For example, the first side wall 110 and the second side wall 120 can be perpendicular to the width direction of the cabinet 100.

[0096] For example, the first end wall 140 and the second end wall 150 can be perpendicular to the length direction of the cabinet 100.

[0097] For example, the evaporator 310 can include but is not limited to a finned heat exchanger, a micro-channel heat exchanger, etc.

[0098] For example, the evaporator 310 can include but is not limited to a plate heat exchanger, a U-shaped heat exchanger, a V-shaped heat exchanger, etc.

[0099] For example, the evaporator 310 can be vertically arranged or can be arranged obliquely.

[0100] For example, the condenser 320 can include but is not limited to a finned heat exchanger, a micro-channel heat exchanger, etc.

[0101] For example, the condenser 320 can include but is not limited to a plate heat exchanger, a U-shaped heat exchanger, a V-shaped heat exchanger, etc.

[0102] Exemplarily, one or more condensers 320 can be arranged in the outdoor air duct 210. When multiple condensers 320 are arranged in the outdoor air duct 210, the multiple condensers 320 can be of the same type or of different types. For example, the multiple condensers 320 can all be U-shaped heat exchangers, or the multiple condensers 320 can all be V-shaped heat exchangers, or the multiple condensers 320 can be partly U-shaped heat exchangers and partly V-shaped heat exchangers.

[0103] Continuing to refer to Figure 1 As shown, the machine room 10 has a return air inlet and a supply air outlet, both of which are in communication with the space in the machine room 10, and the air conditioner 20 is arranged outside the machine room 10. The indoor air inlet of the air conditioner 20 is in communication with the return air inlet, and the high-temperature air in the machine room 10 flows into the indoor air duct 220 through the return air inlet. The indoor air outlet of the air conditioner 20 is in communication with the supply air outlet, and the indoor air is cooled in the indoor air duct 220 and then flows back into the machine room 10 through the supply air outlet. In this way, the air conditioner 20 is arranged outside the machine room 10, does not occupy the space in the machine room 10, and facilitates the arrangement of electronic equipment in the machine room 10.

[0104] Exemplarily, the return air inlet can be connected to the indoor air inlet through a return air duct 30 to make the indoor air inlet in communication with the return air inlet. The supply air outlet can be connected to the indoor air outlet through a supply air duct 40 to make the indoor air outlet in communication with the supply air outlet.

[0105] Exemplarily, the second side wall 120 can be arranged close to the side wall of the machine room 10.

[0106] Exemplarily, the space in the machine room 10 can be in communication with the indoor air duct 220 of one or more air conditioners 20, so that the air in the machine room 10 can be cooled by the multiple air conditioners 20.

[0107] When the space in the machine room 10 is in communication with the indoor air duct 220 of multiple air conditioners 20, the multiple air conditioners 20 in communication with the space in the machine room 10 can be arranged along the length direction of the machine case 100.

[0108] Exemplarily, the data center can include one or more machine rooms 10, and each machine room 10 can be provided with a corresponding air conditioner 20 outside. The air in each machine room 10 can be cooled by the corresponding air conditioner 20.

[0109] As Figures 2-4 As shown, the indoor air duct 220 is provided with a first air fan 410, which is used to drive the indoor air to flow from the indoor air inlet to the indoor air outlet along the indoor air duct 220.

[0110] A second fan 420 is installed inside the outdoor air duct 210. The second fan 420 is used to drive the outdoor air to flow from the outdoor air inlet along the outdoor air duct 210 to the outdoor air outlet.

[0111] For example, the indoor air duct 220 includes an indoor air inlet duct 221 and an indoor air outlet duct 222. The indoor air inlet is located on the duct wall of the indoor air inlet duct 221 and communicates with it. The indoor air outlet is located on the duct wall of the indoor air outlet duct 222 and communicates with it. At least one of the indoor air inlet duct 221 and the indoor air outlet duct 222 is equipped with an evaporator 310. In this way, the evaporator 310 is easier to install.

[0112] For example, the indoor air inlet duct 221 and the indoor air outlet duct 222 are arranged vertically.

[0113] In some possible implementations, the first fan 410 is located in one of the indoor air inlet duct 221 and the indoor air outlet duct 222 of the indoor air duct 220, while the evaporator 310 is located in the other of the indoor air inlet duct 221 and the indoor air outlet duct 222. In this way, at least part of the first fan 410 and the evaporator 310 are located in different air ducts 200 in the indoor air inlet duct 221 and the indoor air outlet duct 222, which makes the arrangement of the first fan 410 and the evaporator 310 more convenient.

[0114] like Figure 2 , Figure 3 As shown, in some possible embodiments, the first end wall 140 or the second end wall 150 is provided with an indoor maintenance opening, which communicates with the indoor air duct 220. An indoor maintenance door 180 is provided at the indoor maintenance opening for sealing the indoor maintenance opening. In this way, the indoor maintenance opening and the indoor maintenance door 180 do not occupy the space in the length direction of the chassis 100, which is beneficial to shortening the length of the chassis 100, or to setting indoor air inlets and outlets with a larger flow area.

[0115] For example, the first end wall 140 is provided with an indoor maintenance opening, and an indoor maintenance door 180 is openable and closable and connected to the first end wall 140.

[0116] In some possible implementations, the air conditioner 20 also includes an electrical control cabinet 500, which can be used to supply power to and control the electrical equipment of the air conditioner 20. The electrical control cabinet 500 is located on the first end wall 140 or the second end wall 150. In this way, the electrical control cabinet 500 does not occupy the space in the length direction of the casing 100, which is beneficial to shortening the length of the casing 100, or to facilitate the setting of indoor air inlets and outlets with larger airflow areas.

[0117] For example, the indoor maintenance port and the electrical control cabinet 500 are both located on the first end wall 140 or the second end wall 150, and the indoor maintenance door 180 and the indoor maintenance port are arranged along the width direction of the casing 100. This facilitates the maintenance of the air conditioner 20 by the operator.

[0118] For example, both the indoor maintenance port and the electrical control cabinet 500 are located on the first end wall 140.

[0119] For example, the electrical control cabinet 500 is located between the first side wall 110 and the partition 170. In this way, when maintaining the electrical control cabinet 500, it is not easy to cause pollution to the indoor air duct 220, and thus it is not easy to cause pollution to the environment inside the machine room 10 through the indoor air.

[0120] like Figure 4 As shown, in some possible embodiments, the refrigerant-driven component 330 is disposed between the first sidewall 110 and the partition 170, and is located below the outdoor air duct 210. This minimizes the risk of contamination of the indoor air duct 220 during maintenance of the refrigerant-driven component 330, thus reducing the likelihood of indoor air contamination of the environment within the machine room 10. Furthermore, the location of the refrigerant-driven component 330 below the outdoor air duct 210 facilitates its installation and maintenance, and also promotes the flow of outdoor air along the outdoor air duct 210.

[0121] For example, a partition plate is provided between the first side wall 110 and the partition plate 170. The partition plate divides the space between the first side wall 110 and the partition plate 170 into an outdoor air duct 210 located between the partition plate and the top wall 130, and an equipment installation cavity located between the partition plate and the bottom wall 160. The refrigerant drive component 330 is disposed in the equipment installation cavity.

[0122] For example, the partition, the first sidewall 110, the partition 170 and the top wall 130 are used to enclose and form an outdoor air duct 210.

[0123] For example, the condenser 320 can be mounted on a partition plate.

[0124] In some possible implementations, a filter 700 is also provided within the indoor air duct 220, positioned between the indoor air inlet and the evaporator 310. This allows the filter 700 to filter the indoor air, thereby improving the cleanliness of the indoor air supplied to the machine room 10 from the indoor air outlet. Furthermore, the filter 700 is positioned upstream of the evaporator 310 in the direction of indoor air flow, resulting in higher cleanliness of the indoor air flowing to the evaporator 310, which helps maintain the performance of the evaporator 310.

[0125] Exemplarily, the filter screen 700 is fixedly arranged on the evaporator 310, so that the filter screen 700 is convenient to install.

[0126] In some possible embodiments, the indoor air inlet is located above the indoor air outlet.

[0127] In some possible embodiments, the indoor air inlet air duct 221 is located above the indoor air outlet air duct 222, and the lower part of the indoor air inlet air duct 221 communicates with the upper part of the indoor air outlet air duct 222. In this way, the hot air located at the upper part of the space in the machine room 10 can flow into the indoor air duct 220 through the indoor air inlet, and the indoor air cooled in the indoor air duct 220 can be supplied to the lower part of the space in the machine room 10 through the indoor air outlet, which is conducive to improving the heat dissipation effect of the indoor air on the electronic equipment arranged in the machine room 10.

[0128] In some possible embodiments, the indoor air inlet and the indoor air outlet are both arranged on the second side wall 120. In this way, the return air duct 30 does not need to be arranged above the cabinet 100, which is conducive to saving the space in the height direction of the cabinet 100 and facilitating the arrangement of the air conditioner 20. In addition, the indoor air inlet and the indoor air outlet do not occupy the space of the top wall 130, which is conducive to the arrangement of the outdoor air inlet and the outdoor air outlet on the top wall 130.

[0129] Exemplarily, the first air fan 410 can be arranged at the second side wall 120.

[0130] For example, the first air fan 410 can be arranged at the indoor air inlet, and the evaporator 310 can be arranged in the indoor air outlet air duct 222. The first air fan 410 is located above the evaporator 310, and the first air fan 410 can be arranged upstream of the evaporator 310 along the indoor air flow direction.

[0131] In some possible embodiments, the outdoor air inlet is arranged on one of the first side wall 110 and the top wall 130, and the outdoor air outlet is arranged on the other one of the first side wall 110 and the top wall 130. In this way, the outdoor air inlet and the outdoor air outlet can both have a large flow area.

[0132] Exemplarily, the outdoor air inlet is arranged on the top wall 130, and the outdoor air outlet is arranged on the first side wall 110. In this way, in the scene where the machine room 10 of the data center is multi-layered or it is inconvenient to discharge hot air above the air conditioner 20, the outdoor air after heat exchange with the condenser 320 can be discharged to the external environment along the width direction of the cabinet 100.

[0133] Exemplarily, the second air fan 420 can be arranged at the first side wall 110.

[0134] For example, the second fan 420 can be located at the outdoor air outlet, and the second fan 420 can be located downstream of the condenser 320 in the direction of outdoor air flow.

[0135] Figure 5 for Figure 2 The diagram provided shows a view of one side of the second side wall of the air conditioner.

[0136] like Figure 5 As shown, in some possible embodiments, the indoor air duct 220 is provided with a plurality of first fans 410 arranged along the length of the chassis 100. This facilitates the arrangement of a large number of first fans 410, which can increase the air volume of the indoor air flowing through the indoor air duct 220, thereby improving the efficiency of the evaporator 310 in cooling the indoor air.

[0137] For example, multiple first fans 410 are arranged in a row along the length of the casing 100.

[0138] For example, a row of first fans 410 may be arranged on the chassis 100 along the length of the chassis 100.

[0139] Figure 6 for Figure 2 The diagram provided shows a view of one side of the first side wall of the air conditioner.

[0140] like Figure 6 As shown, in some possible embodiments, the outdoor air duct 210 is provided with a plurality of second fans 420 arranged along the length of the chassis 100. This facilitates the arrangement of a large number of second fans 420, which can increase the air volume of the outdoor air flowing through the outdoor air duct 210 and provide a larger cooling capacity.

[0141] For example, multiple second fans 420 are arranged in a row along the length of the casing 100.

[0142] For example, two rows of second fans 420 may be arranged in a row along the length of the chassis 100.

[0143] In some examples, the refrigerant drive component 330 may include a compressor 331 connected between the evaporator 310 and the condenser 320. The compressor 331 compresses the refrigerant from the evaporator 310 and delivers it to the condenser 320. Thus, when the external ambient temperature is high, the compressor 331, condenser 320, throttling device, and evaporator 310 form a refrigerant circulation loop. This allows heat to be carried away from the refrigerant by outdoor airflow, thereby cooling the indoor airflow passing through the indoor air duct 220.

[0144] In some examples, the refrigerant drive component 330 may include a refrigerant pump 332, which may be connected between the condenser 320 and the throttling device. The refrigerant pump 332 is used to deliver refrigerant from the condenser 320 to the throttling device. In this way, when the temperature in the external environment is low, the condenser 320, the refrigerant pump 332, the throttling device, and the evaporator 310 can form a refrigerant circulation loop, so that outdoor air can be fully utilized to provide cooling capacity when the temperature in the external environment is low, which helps to improve the energy efficiency of the air conditioner 20.

[0145] The evaporator 310, the throttling device, the condenser 320, the compressor 331 and the refrigerant pump 332 can be connected by pipes. The pipes can pass through the partition 170 and the partition plate, and the pipes are sealed to the partition 170 and the partition plate.

[0146] Figure 7 This is a schematic diagram of one side view of the second sidewall of an air conditioner provided in an embodiment of this application.

[0147] like Figure 7 As shown, in some examples, two rows of first fans 410 arranged in a row along the length of the chassis 100 can be provided on the chassis 100.

[0148] Figure 8 This is a schematic diagram showing a view from one side of the first sidewall of an air conditioner provided in an embodiment of this application. Figure 9 This is a schematic diagram showing a view from one side of the first end wall of another air conditioner provided in an embodiment of this application. Figure 10 This is a top view schematic diagram of another type of air conditioner provided in the embodiments of this application.

[0149] like Figures 8-10 As shown, in some examples, the outdoor air inlet is located on the first side wall 110, and the outdoor air outlet is located on the top wall 130. In this way, in scenarios where the data center server room 10 is a single-story building or where it is convenient to exhaust air from above the air conditioner 20, the rising of hot air can be used to make the outdoor air flow in the outdoor air duct 210, making it convenient to exhaust the outdoor air after heat exchange with the condenser 320 to the external environment. The outdoor air exhausted from the outdoor air outlet is less likely to flow back into the outdoor air duct 210 through the outdoor air inlet.

[0150] For example, the second fan 420 may be located at the top wall 130.

[0151] In some possible embodiments, at least part of the partition 170 is an inclined structure 171, the upper end of the inclined structure 171 is connected to the top wall 130, and the lower end of the inclined structure 171 is deviated towards the side close to the first side wall 110 relative to the upper end of the inclined structure 171. In this way, the space available on the top wall 130 for arranging the outdoor air inlet and the outdoor air outlet can be larger, which facilitates the arrangement of the outdoor air inlet and the outdoor air outlet on the top wall 130. In addition, when the indoor air inlet is located on the second side wall 120, the inclined structure 171 can also play a role in guiding the indoor air from the indoor air inlet air duct 221 to the indoor air outlet air duct 222.

[0152] For example, the partition 170 includes the inclined structure 171 and a vertical structure 172, the upper end of the inclined structure 171 is connected to the top wall 130, the lower end of the inclined structure 171 is connected to the upper end of the vertical structure 172, the lower end of the vertical structure 172 is connected to the bottom wall 160, and the inclined structure 171 is used to form part of the air duct wall of the indoor air inlet air duct 221 and the outdoor air duct 210.

[0153] In some possible embodiments, the partition 170 can also be vertically arranged.

[0154] Figure 11 FIG. 6 is a schematic view of the second side wall of another air conditioner according to an embodiment of the present application, Figure 12 FIG. 7 is a schematic view of the first end wall of another air conditioner according to an embodiment of the present application, Figure 13 FIG. 8 is a schematic view of another air conditioner according to an embodiment of the present application.

[0155] As shown in FIG. 1, Figures 11-13 In some possible embodiments, the indoor air inlet is arranged on the top wall 130, and the indoor air outlet is arranged on the second side wall 120. In this way, the indoor air flows from the indoor air inlet air duct 221 to the indoor air outlet air duct 222 with less resistance.

[0156] For example, the evaporator 310 can be arranged in the indoor air inlet air duct 221, and the first air fan 410 can be arranged in the indoor air outlet air duct 222.

[0157] For example, the evaporator 310 can be a V-shaped heat exchanger, so that the heat exchange surface of the evaporator 310 is larger, which facilitates the cooling of the indoor air.

[0158] For example, the first air fan 410 can be arranged at the indoor air outlet, the evaporator 310 can be arranged in the indoor air inlet air duct 221, the first air fan 410 can be located below the evaporator 310, and the first air fan 410 can be arranged downstream of the evaporator 310 along the flow direction of the indoor air.

[0160] As shown in FIG. 6, the indoor air duct 220 can be provided with a plurality of evaporators 310 arranged at intervals along the flow direction of the indoor air. In this way, the indoor air can be subjected to multiple heat exchanges by the plurality of evaporators 310, which is conducive to reducing the temperature of the indoor air flowing out of the indoor air outlet. In addition, the indoor air will be mixed after passing through the evaporators 310 upstream of the flow direction of the indoor air, which is conducive to uniform heat exchange between the indoor air and the evaporators 310 downstream of the flow direction of the indoor air. Figure 14 Figure 15 As shown in FIG. 6, the indoor air duct 220 can be provided with a plurality of evaporators 310 arranged at intervals along the flow direction of the indoor air. In this way, the indoor air can be subjected to multiple heat exchanges by the plurality of evaporators 310, which is conducive to reducing the temperature of the indoor air flowing out of the indoor air outlet. In addition, the indoor air will be mixed after passing through the evaporators 310 upstream of the flow direction of the indoor air, which is conducive to uniform heat exchange between the indoor air and the evaporators 310 downstream of the flow direction of the indoor air.

[0161] For example, in some examples in which the indoor air duct 220 is provided with a plurality of evaporators 310 arranged at intervals along the flow direction of the indoor air, some of the evaporators 310 are arranged in the indoor air inlet duct 221 and some of the evaporators 310 are arranged in the indoor air outlet duct 222, so as to facilitate the arrangement of the plurality of evaporators 310 arranged at intervals along the flow direction of the indoor air in the indoor air duct 220.

[0162] In some examples, the first air fan 410 is arranged upstream of all the evaporators 310 along the flow direction of the indoor air.

[0163] In some examples, the first air fan 410 is arranged downstream of all the evaporators 310 along the flow direction of the indoor air.

[0164] In some examples, the first air fan 410 is arranged upstream of some of the evaporators 310 along the flow direction of the indoor air and downstream of some of the evaporators 310 along the flow direction of the indoor air.

[0165] In some examples in which the indoor air duct 220 is provided with a plurality of evaporators 310 arranged at intervals along the flow direction of the indoor air, the filter screen 700 can be arranged on the evaporators 310 close to the indoor air inlet.

Figure 17 FIG. 4 is a schematic view of a first end wall of an air conditioner according to an embodiment of the present application, viewed from a side thereof, Figure 18 FIG. 4 is a schematic view of a first end wall of an air conditioner according to an embodiment of the present application, viewed from a side thereof.

[0167] As shown in FIG. 6, the indoor air duct 220 can be provided with a plurality of evaporators 310 arranged at intervals along the flow direction of the indoor air. In this way, the indoor air can be subjected to multiple heat exchanges by the plurality of evaporators 310, which is conducive to reducing the temperature of the indoor air flowing out of the indoor air outlet. In addition, the indoor air will be mixed after passing through the evaporators 310 upstream of the flow direction of the indoor air, which is conducive to uniform heat exchange between the indoor air and the evaporators 310 downstream of the flow direction of the indoor air. Figures 16-18 ​As shown, in some possible embodiments, the outdoor air duct 210 is further provided with a spraying device 600, which is configured to spray spraying water into the outdoor air duct 210. In this way, the spraying device 600 can spray the outdoor air as wet cold air, which has a good heat absorption effect on the refrigerant of the condenser 320, and is beneficial to heat dissipation of the refrigerant in the condenser 320.

[0168] In some examples, the condenser 320 can be provided with the spraying device 600 downstream of the outdoor air flow direction. That is, the spraying device 600 can be provided between the outdoor air outlet and the condenser 320.

[0169] In some examples, the condenser 320 can be provided with the spraying device 600 upstream of the outdoor air flow direction. That is, the spraying device 600 can be provided between the outdoor air inlet and the condenser 320.

[0172] In some examples, the condenser 320 can be provided with the spraying device 600 upstream of the outdoor air flow direction. That is, the spraying device 600 can be provided between the outdoor air inlet and the condenser 320.

[0173] In some examples in which the spraying device 600 is arranged in the outdoor air duct 210, an open water tank 800 is further arranged in the outdoor air duct 210.
