[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0035] The following is for reference. Figures 1-9 The present application describes an air conditioner outdoor unit 100, which is arranged outdoors.

[0036] An air conditioner outdoor unit 100 according to an embodiment of this application includes an electrical control box 10 and a housing assembly 20.

[0037] Combination Figure 2 and Figure 4 As shown, the electrical control box 10 forms a heat dissipation duct 101, and the heat dissipation duct 101 has an air inlet 1011 and an air outlet 1012. The air inlet 1011 is used to allow air to flow into the heat dissipation duct 101, and the air outlet 1012 is used to allow air to be discharged from the heat dissipation duct 101.

[0038] Combination Figure 3 and Figure 4 As shown, the shell assembly 20 includes a shell body 21 and a panel 22. The panel 22 is mounted on the shell body 21, and the panel 22 and the shell body 21 define a cavity. A partition 30 is provided in the cavity, which is used to separate the cavity and form a compressor cavity 201 and a fan cavity 202.

[0039] The fan cavity 202 is equipped with a heat exchanger and a fan, which forms an airflow on one side of the fan cavity 202 to improve the heat exchange effect at the heat exchanger. The compressor cavity 201 is equipped with a compressor and pipelines, and the electrical control box 10 is located on one side of the compressor cavity 201 to control the operating status of the equipment (such as the compressor and fan) in the outdoor unit 100 of the air conditioner.

[0040] Reference Figure 6As shown, the partition plate 30 has a first connecting hole 301, and the air outlet 1012 of the heat dissipation duct 101 is located at the first connecting hole 301 and communicates with the fan cavity 202, so that the air in the heat dissipation duct 101 can flow to one side of the fan cavity 202 through the first connecting hole 301; combined with Figure 1 and Figure 2 As shown, a second connecting hole 2201 is provided at panel 22, and the air inlet 1011 of the heat dissipation duct 101 is located at the second connecting hole 2201, so that the air inlet 1011 of the heat dissipation duct 101 is connected to the outside of the housing assembly 20 through the second connecting hole 2201. Thus, air from outside the housing assembly 20 can flow directly into the heat dissipation duct 101 through the second connecting hole 2201, and after flowing through the heat dissipation duct 101, it flows to the fan cavity 202 side through the first connecting hole 301 to form an airflow through the electrical control box 10, thereby dissipating heat and cooling the electrical control box 10.

[0041] Understandably, during fan operation, a rapidly flowing airflow can be formed within the fan cavity 202, creating a negative pressure at the first connecting hole 301 of the partition plate 30. Under this negative pressure, air in the heat dissipation duct 101 is drawn towards one side of the fan cavity 202. Simultaneously, the heat dissipation duct 101 can supplement air through the air inlet 1011 and the second connecting hole 2201, allowing air from outside the housing assembly 20 to flow into the heat dissipation duct 101 via the air inlet 1011. Thus, as air flows through the heat dissipation duct 101, it can exchange heat with the components in the electrical control box 10 (such as power devices 1221, heat sinks 13, etc.), transferring the heat towards the fan cavity 202 before discharging it from the housing assembly 20, thereby achieving heat dissipation and cooling at the electrical control box 10.

[0042] It should be noted that currently, in the outdoor unit 100 of an air conditioner, the electrical control box 10 is located within the casing of the outdoor unit 100. The electrical control box 10 generates heat during operation, and cooling is necessary to ensure its stability and reliability. In related technologies, the electrical control box 10 typically works in conjunction with the refrigerant piping for heat exchange and cooling, resulting in a complex structure at the electrical control box 10. This makes its placement within the outdoor unit 100 inconvenient and increases the production cost of the outdoor unit 100. In some outdoor units 100, air flowing through the electrical control box 10 is used for heat dissipation and cooling. However, due to the high air temperature, the heat dissipation effect at the electrical control box 10 is poor, especially in high-temperature environments where the electrical control box 10 overheats significantly, affecting the performance of the air conditioner.

[0043] According to the embodiment of this application, under the negative pressure on one side of the fan cavity 202, the air outside the shell assembly 20 can directly enter the heat dissipation duct 101 through the air inlet 1011. Moreover, the air entering the heat dissipation duct 101 can enter the fan cavity 202 after flowing through the heat dissipation duct 101, thereby dissipating and cooling the electrical control box 10 through air cooling. Furthermore, the air flowing through the electrical control box 10 directly enters the heat dissipation duct 101 from the outside of the shell assembly 20, which can ensure the air temperature and improve the heat dissipation and cooling effect at the electrical control box 10.

[0044] Combination Figure 8 and Figure 9 As shown, in some embodiments of this application, the electrical control box 10 includes: a box assembly 11, an electrical control assembly 12, and a heat sink 13.

[0045] The box assembly 11 is mounted on the partition plate 30 on one side of the compressor cavity 201, and the box assembly 11 forms the aforementioned heat dissipation duct 101. The radiator 13 can be used to exchange heat with the electronic control assembly 12, and the electronic control assembly 12 and the radiator 13 are arranged within the heat dissipation duct 101. When air flows through the heat dissipation duct 101, the air can exchange heat with the radiator 13 and the electronic control assembly 12 arranged within the heat dissipation duct 101, thereby carrying the heat from the radiator 13 and the electronic control assembly 12 out of the heat dissipation duct 101 (i.e., transferring it to the fan cavity 202 side), thus achieving heat dissipation and cooling of the electronic control box 10.

[0046] It is understandable that the airflow in the heat dissipation duct 101 is formed by generating negative pressure on one side of the fan cavity 202, so that one end of the box assembly 11 forming the air inlet 1011 can be abutted against the inner wall surface of the panel 22 (i.e. the wall surface facing the compressor cavity 201), so that the air flowing into the inside of the shell assembly 20 through the second connecting hole 2201 can directly enter the heat dissipation duct 101, ensuring the air intake effect of the box assembly 11.

[0047] Reference Figure 9 It should be noted that the electronic control assembly 12 may include power devices 1221, capacitive devices (not shown), inductive devices (not shown), and other electronic devices 122. When the electronic control box 10 is in operation, the power devices 1221 (e.g., bridge rectifiers) generate a large amount of heat, while the capacitive and inductive devices generate less heat compared to the power devices 1221. Therefore, the power devices 1221 can be paired with the heat sink 13 to improve the heat dissipation efficiency of the power devices 1221 through heat exchange. Simultaneously, other electronic devices 122 (such as the aforementioned capacitive and inductive devices) can be directly arranged in the heat dissipation duct 101 to carry away heat through the air flowing through the duct 101, thus achieving heat dissipation and cooling.

[0048] In some embodiments of this application, the box assembly 11 includes a box body 111 and a box cover 112. The box body 111 forms a receiving groove that opens to one side in a first direction. The box cover 112 covers the open end of the receiving groove, and the box cover 112 and the box body 111 define a heat dissipation duct 101. When the box assembly 11 is assembled in the outdoor unit 100 of an air conditioner, the aforementioned "first direction" can be the left-right direction of the outdoor unit 100.

[0049] Combination Figure 2 and Figure 9 As shown, when the box assembly 11 is arranged at the partition 30, the box cover 112 is fitted to the partition 30 to improve the assembly reliability between the box assembly 11 and the partition 30, and the box body 111 is open to the side facing the partition 30. The box body 111 and the box cover 112 are connected and fitted together to form the aforementioned heat dissipation duct 101 between them. The electronic control assembly 12 can be arranged within the heat dissipation duct 101, and the extension direction of the heat dissipation duct 101 is parallel to the first plate segment 31 of the partition 30 (i.e., the plate segment structure in the partition 30 that fits and fits with the box cover 112).

[0050] It should be noted that the connection method between the lid 112 and the box body 111 is not specifically limited here. For example, the lid 112 and the box body 111 can be fixedly connected by a snap-fit, or the lid 112 and the box body 111 can be fixedly connected by a connector, etc. At the same time, the cooperation method between the box assembly 11 and the middle partition 30 is not specifically limited, as long as it can satisfy the requirement of fixing the box assembly 11 at the middle partition 30. That is to say, the box assembly 11 can be fixed relative to the middle partition 30 by directly or indirectly connecting to it.

[0051] In a further embodiment of this application, the box assembly 11 is provided with a partition rib 114. The partition rib 114 is used to separate the heat dissipation air duct 101 and form a plurality of sub-air ducts 1013. The plurality of sub-air ducts 1013 are arranged independently of each other. That is to say, the air flowing through any one sub-air duct 1013 can be directly discharged to the side of the fan cavity 202 through the first connecting hole 301, thereby avoiding the air flowing through the sub-air duct 1013 from flowing into other sub-air ducts 1013 and causing a reduction in heat dissipation efficiency.

[0052] The partition rib 114 can be provided on at least one of the cover 112 and the body 111. Figure 8 and Figure 9As shown, a partition rib 114 is disposed on the housing 111 and extends from the housing 111 toward the cover 112, dividing the housing assembly 11 to form two sub-air ducts 1013. Preferably, the partition rib 114 is arranged laterally to divide the heat dissipation air duct 101 into multiple sub-air ducts 1013 arranged along a third direction (i.e., the vertical direction of the outdoor unit 100), and the partition rib 114 is adapted to avoid the PCB board 121 arranged vertically in the housing assembly 11.

[0053] Understandably, when multiple sub-channels 1013 are divided at the heat dissipation channel 101, the electrical components 122 in the electronic control assembly 12 can be arranged in separate zones according to heat dissipation requirements. This allows the electrical components 122 to be placed in multiple sub-channels 1013, enabling heat dissipation for each component 122 according to its specific needs, thus improving the heat dissipation efficiency at the electronic control box 10. For example, capacitive and inductive components can be arranged in two separate sub-channels 1013, preventing airflow through the capacitive components from flowing into the sub-channel 1013 containing the inductive components, and vice versa. This ensures that the air cooling actions of the electrical components 122 are independent, thereby improving heat dissipation efficiency.

[0054] Combination Figure 8 and Figure 9 As shown, in a specific embodiment of this application, the heat sink 13 and the power device 1221 are arranged within the same sub-duct 1013. The power device 1221 is adapted to be arranged in close contact with the heat sink 13 so as to further transfer heat outward through the heat sink 13 and improve the heat dissipation effect at the power device 1221.

[0055] In a further embodiment of this application, the heat sink 13 includes a heat sink 132 and a heat sink substrate 131. The heat sink substrate 131 can be used to be attached to an electrical device 122 (such as a power device 1221). The heat sink 132 is disposed on the side of the heat sink substrate 132 away from the electrical device 122. The direction of the heat sink 132 is parallel to the direction of the sub-air duct 1013 (referring to the sub-air duct 1013 where the heat sink 13 is located) to improve the airflow effect when the air in the sub-air duct 1013 passes through the heat sink 13.

[0056] In some embodiments of this application, the electrical control assembly 12 includes a PCB board 121, and electrical components 122 can be arranged on the PCB board 121. The electrical control box 10 also includes a heat sink bracket 14, which is connected to the PCB board 121 and is used to mount a heat sink 13 so that the heat sink 13 is fixed on the PCB board 121 by the heat sink bracket 14.

[0057] Reference Figure 9The heat sink bracket 14 is arranged around the power device 1221 in the circumferential direction to shield the power device 1221 in the air intake direction of the sub-air duct 1013, preventing the power device 1221 from being exposed, thereby preventing water, dust and other pollutants in the air from adhering to the power device 1221, and playing a protective role for the power device 1221, so as to improve the stability and reliability of the operation of the electrical control box 10.

[0058] Combination Figure 6 and Figure 7 As shown, in some embodiments of this application, the partition 30 includes a first segment 31 and a second segment 32. The first segment 31 is connected to the box assembly 11, and the box assembly 11 is arranged on the side surface of the first segment 31 facing the compressor cavity 201 to place the box assembly 11 in the compressor cavity 201. The second segment 32 is connected to the side of the first segment 31 away from the panel 22, and the second segment 32 is inclined relative to the first segment 31 to form a corner structure at the first segment 31 and the second segment 32, so that the box assembly 11 is arranged opposite to the second segment 32 in a second direction. Here, "second direction" refers to the front-rear direction of the air conditioner outdoor unit 100.

[0059] like Figure 4 As shown, when the second plate segment 32 is bent relative to the first plate segment 31, the surface of the second plate segment 32 facing the fan cavity 202 can be positioned opposite the back plate in the shell body 21 in the front-back direction. During fan operation, air enters the fan cavity 202 from the back plate side of the shell assembly 20 and is transported to the panel 22 side under the action of the fan. Since the second plate segment 32 is positioned opposite the air inlet side of the fan cavity 202, negative pressure can be formed in the air inside the fan cavity 202 on the side of the partition 30 facing the fan cavity 202, allowing air in the heat dissipation duct 101 to flow to the fan cavity 202 side through the first connecting hole 301.

[0060] Combination Figure 4 and Figure 6 As shown, in some embodiments of this application, a first connecting hole 301 is formed on the second plate segment 32, and the first connecting hole 301 is disposed near the connection between the first plate segment 31 and the second plate segment 32, so as to facilitate the air outlet 1012 of the heat dissipation duct 101 in the electrical control box 10 to be disposed opposite to the first connecting hole 301, and the box assembly 11 can maintain a close fit with the first plate segment 31.

[0061] Reference Figure 4The second plate segment 32 and the panel 22 are arranged opposite to each other in the second direction, so that the first connecting hole 301 and the second connecting hole 2201 can be arranged opposite to each other in the second direction, and the heat dissipation air duct 101 can be arranged through the second direction, that is, the air inlet 1011 and the air outlet 1012 of the heat dissipation air duct 101 are arranged on both sides of the electrical control box 10 in the second direction, thereby improving the smoothness of the air flow when passing through the heat dissipation air duct 101.

[0062] like Figure 5 As shown, in some other embodiments of this application, a first connecting hole 301 is formed on the first plate segment 31, and the first connecting hole 301 is disposed near the connection between the first plate segment 31 and the second plate segment 32, so that air in the heat dissipation duct 101 can flow into the fan cavity 202 side through the first plate segment 31. At this time, the air outlet 1012 of the box assembly 11 is disposed opposite to the first plate segment 31, and the air entering the heat dissipation duct 101 through the panel 22 can be discharged through the air outlet 1012 to the first connecting hole 301 formed in the first plate segment 31 and enter the fan cavity 202 side.

[0063] It should be noted that the first connecting hole 301 can also be provided at both the first plate segment 31 and the second plate segment 32. When the heat dissipation duct 101 has multiple sub-ducts 1013, each sub-duct 1013 has both an air inlet structure and an air outlet structure.

[0064] In some embodiments, the air outlet structure of each sub-duct 1013 may be connected to the same first connecting hole 301; in other embodiments, there are multiple first connecting holes 301, and the air outlet structure of each sub-duct 1013 is connected to one first connecting hole 301; in other embodiments, there are multiple first connecting holes 301, and each first connecting hole 301 is connected to the air outlet structure of at least one sub-duct 1013.

[0065] It is understandable that placing the first connecting hole 301 near the corner of the first plate segment 31 and the second plate segment 32 can ensure the length of the heat dissipation duct 101 in the second direction while facilitating the connection between the air outlet 1012 of the heat dissipation duct 101 and the first connecting hole 301.

[0066] In some embodiments of this application, the partition 30 is arranged in a vertical direction to divide the cavity into a horizontally arranged fan cavity 202 and compressor cavity 201.

[0067] Combination Figure 2 and Figure 4As shown, the first section 31 of the partition 30 is arranged vertically and extends in the front-to-back direction, so that the first section 31 is set perpendicular to the panel 22. This allows the electrical control box 10 to be fully exposed after the panel 22 is removed, making it easier for operators to remove and install the electrical control box 10 from the front side of the outdoor unit 100 (i.e. the side where the panel 22 is installed), thus reducing the difficulty of removing and installing the electrical control box 10.

[0068] like Figure 3 As shown, in some embodiments of this application, panel 22 includes a first panel 221 and a second panel 222, which are arranged sequentially and connected along a first direction. The adjacent portions of the first panel 221 and the second panel 222 are connected and engaged with the first segment 31 of the partition 30. That is, the first panel 221 is the component in panel 22 corresponding to the fan cavity 202, and the second panel 222 is the component in panel 22 corresponding to the compressor cavity 201. This facilitates the assembly of the housing assembly 20 with the partition 30 and facilitates the inspection and maintenance of the devices in the fan cavity 202 and the compressor cavity 201.

[0069] Understandably, when it is necessary to disassemble the electrical control box 10, it is only necessary to remove the second panel 222 from the housing body 21 to open the compressor cavity 201 on one side of the panel 22, making it convenient for operators to install and remove the electrical control box 10 from the panel 22 side. Similarly, if it is necessary to inspect and repair the devices (such as fans, heat exchangers, etc.) in the fan cavity 202, removing the first panel 221 will fully expose the devices in the fan cavity 202 from one side of the panel 22, making it convenient for operators to operate.

[0070] like Figure 3 As shown, in some embodiments of this application, the shell body 21 includes a top cover 211, and a connection structure that mates with the panel 22 can be formed at the top cover 211. The top of the panel 22 can mate with the connection structure so that the panel 22 and the top cover 211 are fixedly connected.

[0071] like Figure 8 and Figure 9 As shown, in some embodiments of this application, the electronic control component 12 includes a PCB board 121, which is arranged inside the box assembly 11 and is parallel to the first board segment 31, thereby ensuring the air intake effect at the electronic control box 10.

[0072] Understandably, when the PCB board 121 is arranged parallel to the first board segment 31, the side of the PCB board 121 can be positioned opposite to the air intake direction. The PCB board 121 can fully avoid the heat dissipation airflow 101 formed by the box assembly 11, thus ensuring the air intake effect at the electrical control box 10. At the same time, the vertically arranged PCB board 121 can increase the difficulty of contaminants adhering to the PCB board 121, reducing the adhesion of dust and other contaminants to the PCB board 121.

[0073] like Figure 2 As shown, in a further embodiment of this application, the heat sink 13 is disposed on the side of the PCB board 121 away from the first board segment 31; in other embodiments of this application, the heat sink 13 is disposed on the side of the PCB board 121 opposite to the first board segment 31. Thus, the heat sink 13 can be arranged in a position suitable for heat exchange with the air in the heat dissipation duct 101, so that the air entering the heat dissipation duct 101 through the air inlet 1011 can be directly blown towards the heat sink 13, improving the heat dissipation and cooling efficiency of the heat sink 13.

[0074] In some embodiments of this application, the electronic control assembly 12 further includes an electrical component 122, which is mounted on the PCB board 121 and can exchange heat with the heat sink 13.

[0075] It is understood that the PCB board 121 serves as the mounting carrier for the electrical components 122, and the electrical components 122 include various functional devices, meaning there are multiple electrical components 122 on the PCB board 121. The heat sink 13 can cooperate with at least a portion of the multiple electrical components 122 for heat exchange to improve the heat exchange efficiency of the electrical components 122. Specifically, the heat sink 13 typically cooperates with the electrical components 122 that generate a significant amount of heat during the operation of the control box 10 to enhance the local heat dissipation capacity of the control box 10 and prevent excessively high local temperatures in the control box 10.

[0076] In some embodiments of this application, the electrical components 122 and the heat sink 13 are arranged on the same side of the PCB board 121, thereby improving the production efficiency of the electronic control assembly 12 and reducing the assembly difficulty of the electronic control assembly 12 on the box assembly 11, thus improving assembly efficiency. It is understood that compared to an electronic control assembly 12 with electrical components 122 arranged on both sides of the PCB board 121, arranging the electrical components 122 on the same side of the PCB board 121 is less difficult to process, thereby improving the production efficiency of the electronic control assembly 12. Simultaneously, when assembling the electronic control assembly 12 and the heat sink 13 into the box assembly 11, only the side of the PCB board 121 where the electrical components 122 and the heat sink 13 are arranged needs to reserve clearance space, reducing the assembly difficulty of the electronic control assembly 12 and the box assembly 11.

[0077] like Figure 8 and Figure 9As shown, in some embodiments of this application, the box assembly 11 has a sliding groove 113. One end of the sliding groove 113 near the panel 22 is connected to the air inlet 1011, and the PCB board 121 can slide into the box assembly 11 through the air inlet 1011 or slide out of the box assembly 11 through the air inlet 1011. Thus, the PCB board 121 can slide and engage with the box assembly 11, allowing the PCB board 121 to be arranged in the box assembly 11 or pulled out of the box assembly 11 by a pull-out method, thereby reducing the assembly difficulty of the PCB board 121 and the box assembly 11.

[0078] The PCB board 121 serves as the mounting carrier for the electrical components 122 and the heat sink 13. During the assembly of the electrical control box 10, the electrical components 122 can be installed on the PCB board 121 first, and the heat sink 13 can be fixed on the PCB board 121 by the heat sink bracket 14 arranged on the PCB board 121. Then, the electrical control assembly 12 and the heat sink 13 are assembled together on the box assembly 11. The installation method is that the PCB board 121 and the slide groove 113 slide together, which makes the assembly method of the electrical control box 10 simple.

[0079] Understandably, when the control box 10 needs to be repaired or inspected, the control component 12 and the heat sink 13 can be removed from the box component 11 by pulling them out, without having to disassemble the entire control box 10, thus reducing the difficulty of repairing the control box 10.

[0080] Combination Figure 2 and Figure 8 As shown, in some embodiments of the application, one end of the slide 113 is connected to the air inlet 1011 of the heat dissipation duct 101, allowing the electronic control component 12 to be installed from the air inlet 1011 of the housing assembly 11 into the slide 113. The extension direction of the slide 113 is parallel to the extension direction of the heat dissipation duct 101, allowing the electronic control component 12 to be pulled out of or placed into the housing assembly 11 along the direction of the heat dissipation duct 101.

[0081] Combination Figure 8 and Figure 9 As shown, it should be noted that the box assembly 11 consists of a box body 111 and a box cover 112. A sliding groove 113 can be formed on the box body 111, and the sliding groove 113 can also be formed on the box cover 112. The sliding groove 113 can also be formed by the box body 111 and the box cover 112 in combination. No specific limitation is made here.

[0082] like Figure 9As shown, in a specific embodiment of this application, a groove 113 is formed on the lid 112. The lid 112 includes a main board segment 1121, a first flap 1122, and a second flap 1123. The first flap 1122 and the second flap 1123 are arranged vertically at intervals on the main board segment 1121. The first flap 1122 and the second flap 1123 extend from the side surface of the main board segment 1121 opposite to the box body 111 toward the box body 111. On the side edge of the first flap 1122 and the second flap 1123 away from the main board segment 1121, there are protruding rib structures 1124 extending in opposite directions. The protruding rib structure 1124, the flap structure (first flap 1122 or second flap) and the main board segment 1121 define a groove 113. Two grooves 113 with opposite openings are formed on the lid 112.

[0083] like Figure 3 As shown, in some embodiments of this application, a louver 223 is provided at the second communication hole 2201 of the panel 22 to shield and protect the second communication hole 2201, preventing external contaminants (such as water, dust, etc.) from entering the heat dissipation duct 101 through the second communication hole 2201, thus protecting the electrical control box 10.

[0084] The air conditioner outdoor unit 100 according to the embodiments of this application has at least the following advantages:

[0085] (1) The partition plate 30 is provided with a first connecting hole 301, and the air conditioner outdoor unit 100 is provided with a second connecting hole 2201 at the panel 22, so that the air outside the shell assembly 20 can directly enter the heat dissipation duct 101 of the electrical control box 10 through the second connecting hole 2201. After the air in the heat dissipation duct 101 flows through the heat dissipation duct 101, it is discharged to the side of the fan cavity 202 through the first connecting hole 301. Thus, the negative pressure generated on the side of the fan cavity 202 forms the airflow flowing through the electrical control box 10, and the components in the electrical control box 10 are cooled down by air cooling.

[0086] (2) The heat dissipation duct 101 includes multiple sub-ducts 1013, which can dissipate heat from the electrical components 122 through multiple independent sub-ducts 1013, thereby improving the heat dissipation efficiency at the electrical control box 10.

[0087] (3) The electrical control box 10 is arranged on one side of the compressor cavity 201 in cooperation with the partition plate 30, and the electrical control box 10 is arranged near the panel 22. When the electrical control box 10 needs to be repaired, the electrical control box 10 can be removed from the front of the air conditioner outdoor unit 100, reducing the difficulty of removing and installing the electrical control box 10.

[0088] (4) During the assembly of the electrical control box 10, the electrical control component 12 is assembled with the box component 11 through the PCB board 121 in a sliding fit, so as to reduce the assembly difficulty of the electrical control box 10.

[0089] According to an embodiment of this application, the air conditioner includes the outdoor unit 100 described above. The advantages of the air conditioner and the outdoor unit 100 are the same, and will not be repeated here.
