Between the front 14 and the back 16 of the inner shell. Generally, when the integrated air conditioner is in use, for example, when the integrated air conditioner is placed against a wall, the back surface 16 of the inner casing faces close to the wall. In the following, the front surface 14 of the inner casing is taken as the front, the rear face 16 of the inner casing is taken as the rear, and the two inner casing side surfaces 15 are taken as examples to describe.

In one embodiment, the inner casing 10 is provided with two indoor air outlets 13 , wherein the air outlet side of one wind wheel is connected to one indoor air outlet 13 , and the air outlet side of the other wind wheel is connected to the other indoor air outlet 13 . Connected. That is, the two indoor air outlets 13 are arranged at intervals, and each indoor air outlet 13 can supply air independently, thus increasing the air outlet position on the inner casing 10 and increasing the air supply range. For example, when two indoor air outlets 13 are arranged at intervals in the vertical direction, the air supply range in the vertical direction can be increased, and when the two indoor air outlets 13 are arranged at intervals in the left and right directions, the air supply range in the left and right directions can be increased. Of course, in other embodiments, only one indoor air outlet 13 may be provided, and the air outlet sides of the two wind rotors are both connected to the indoor air outlet 13 .

In one embodiment, at least one indoor air outlet 13 is arranged on the front face 14 of the inner casing, that is, the indoor air outlet 13 is arranged on the front side of the integral air conditioner, so that the air flow can be easily directed to the front and left and right of the integral air conditioner. , it can increase the air supply range of the integral air conditioner, and can also reduce the possibility that the indoor air outlet 13 is blocked by indoor objects. Wherein, two indoor air outlets 13 may be arranged on the front face 14 of the inner casing, or one indoor air outlet 13 may be arranged on the front face 14 of the inner casing, and the other indoor air outlet 13 may be arranged on the side surface 15 of the inner casing. Of course, in other embodiments, the two indoor air outlets 13 may also be provided on the side surface 15 of the inner casing.

There are various installation positions of the indoor air inlet 12 . For example, in one embodiment, at least one indoor air inlet 12 is arranged on the front surface 14 of the inner casing of the inner casing 10 . That is, when one indoor air inlet 12 is provided, the indoor air inlet 12 is provided on the front face 14 of the inner casing, and when two or more indoor air inlets 12 are provided, at least one indoor air inlet 12 is provided on the front face 14 of the inner casing. The indoor air inlet 12 is also arranged on the front side of the integrated air conditioner, so that the possibility of the indoor air inlet 12 being blocked by indoor items can be reduced, and the air intake effect can be ensured. Wherein, two indoor air inlets 12 can be arranged on the front face 14 of the inner casing; or one of the indoor air outlets 13 can be arranged on the front face 14 of the inner casing, and the other indoor air outlet 13 can be arranged on the side surface 15 of the inner casing; or One indoor air outlet 13 is provided on the front side 14 of the inner casing, and the other indoor air outlet 13 is provided on the back side 16 of the inner casing.

In another embodiment, at least one indoor air inlet 12 is provided on the inner casing side 15 of the inner casing 10 . That is, when one indoor air inlet 12 is provided, the indoor air inlet 12 is provided on the side 15 of the inner shell, and when two or more indoor air inlets 12 are provided, at least one indoor air inlet 12 is provided on the side 15 of the inner shell. When the indoor air outlet 13 is arranged on the front face 14 of the inner casing, the distance between the indoor air outlet 13 and the indoor air inlet 12 can be made farther, and the indoor air outlet 13 and the indoor air inlet 12 can face different directions respectively, which can reduce the The possibility that the air outlet air blown from the indoor air outlet 13 is directly sucked into the indoor air inlet 12 can also improve the circulation effect of the indoor air and realize the sufficient circulation and heat exchange of the indoor air. Wherein, two indoor air inlets 12 can be provided on the side 15 of the inner casing, at this time, one indoor air inlet 12 can be provided on each of the two sides of the inner casing 10, two indoor air ducts 11 and two The indoor air inlets 12 are connected in a one-to-one correspondence, and two indoor air inlets 12 can also be provided on each inner shell side 15, and each of the two inner shell sides 15 has an indoor air inlet 12 communicated with one of the indoor air ducts 11, The other indoor air inlets 12 on the two inner shell side surfaces 15 communicate with another indoor air duct 11 . Alternatively, one of the indoor air outlets 13 is arranged on the side surface 15 of the inner casing, and the other indoor air outlet 13 is arranged on the back 16 of the inner casing.

In yet another embodiment, the two indoor air inlets 12 can also be provided on the back 16 of the inner casing. When the indoor air outlet 13 is arranged on the front face 14 of the inner casing, the distance between the indoor air outlet 13 and the indoor air inlet 12 can be made farther, and the indoor air outlet 13 and the indoor air inlet 12 can face different directions respectively, which can reduce the The possibility that the air outlet air blown from the indoor air outlet 13 is directly sucked into the indoor air inlet 12 can also improve the circulation effect of the indoor air and realize the sufficient circulation and heat exchange of the indoor air.

In one embodiment, the two indoor air outlets 13 are arranged at intervals in the up-down direction. In this way, the indoor air outlet 13 can be reasonably selected to discharge air according to the heat exchange mode, so as to achieve a better air supply effect and improve the indoor heat exchange effect. For example, in the heating mode, since the hot air flows upward after being sent out from the indoor air outlet 13, the air can be supplied through the indoor air outlet 13 below, so that the hot air is sent downward as much as possible, so that the hot air can be better distributed indoors. In the cooling mode, since the cold air flows downward after being sent out from the indoor air outlet 13, the air can be supplied through the indoor air outlet 13 above, so that the cold air is sent upward as much as possible, so that the cold air can be better distributed indoors. Optionally, the two indoor air outlets 13 are both provided on the front surface 14 of the inner casing, which increases the air supply range in the up-down direction and also increases the air supply range in the left-right direction. Of course, in other embodiments, the two indoor air outlets 13 may also be distributed at intervals in the left and right directions. Alternatively, the two indoor air outlets 13 are respectively arranged on the two inner shell side surfaces 15 .

In one embodiment, the two wind wheels are arranged at intervals in the up-down direction. The air inlet side of the upper fan rotor communicates with the upper indoor air outlet 13 , and the air inlet side of the lower fan rotor communicates with the lower indoor air outlet 13 . That is, the two fan rotors are arranged in the up-down direction, so that the size of the inner casing 10 in the left-right direction and the front-rear direction can be reduced, thereby reducing the indoor occupied area of the inner casing 10 . In addition, the indoor air outlet 13 at the upper end can also be located at a higher position, so that in the cooling mode, the cold airflow can be sent to a higher position indoors. Of course, in other embodiments, the two wind rotors may also be arranged at intervals in the left and right directions.

In one embodiment, one indoor air inlet 12 is provided and located between two indoor air outlets 13 , and the air inlet sides of the two wind rotors are both connected to the indoor air inlet 12 . Specifically, the indoor air inlet 12 and the two indoor air outlets 13 are both arranged on the front face 14 of the inner casing. This arrangement reduces the number of indoor air inlets 12 on the inner casing 10 and simplifies the structure of the inner casing 10. At the same time, the indoor air on the front side of the inner casing 10 can better enter the indoor air duct 11, which can reduce the possibility that the indoor air inlet 12 and the indoor air outlet 13 are blocked by indoor items, and ensure the air intake effect. Of course, in other embodiments, the indoor air inlet 12 can also be provided on the left side, the right side, the upper side or the lower side of the two wind rotors. Or set the indoor air inlet 12 on the side surface 15 of the inner casing.

In one embodiment, one of the indoor air outlets 13 is located on the upper side of the upper wind rotor, and the other indoor air outlet 13 is located on the lower side of the lower wind rotor. Specifically, the indoor air outlet 13 located above is provided on the upper side of the corresponding fan rotor, and the indoor air outlet 13 located below is provided on the lower side of the corresponding fan rotor. It is equivalent to that the two wind wheels are located between the two indoor air outlets 13 . In this way, the distance between the two indoor air outlets 13 can be made larger, so that the air supply range can be further increased. In the embodiment in which the indoor air inlet 12 is located between the two indoor air outlets 13 , the possibility that the outgoing air flow sent from the indoor air outlet 13 is directly sucked by the indoor air inlet 12 can also be reduced. Of course, in other embodiments, in the up-down direction, the two indoor air outlets 13 can also be arranged between the two wind wheels.

In one embodiment, an air outlet duct 17 is formed between the wind rotor and the indoor air outlet 13 . In the air outlet direction, the air outlet air duct 17 is gradually inclined in a direction away from the other indoor air outlet 13 . In this way, the distance between the two indoor air outlets 13 can be made farther, thereby further increasing the air supply range. For example, when two indoor air outlets 13 are arranged at intervals in the up-down direction, that is, the upper air outlet duct 17 extends obliquely upward, and the lower air outlet duct 17 extends obliquely downward, so that the airflow sent from the upper indoor air outlet 13 It can be sent to a higher position indoors, and the air flow sent by the indoor air outlet 13 below can be better sent to the bottom surface, which can improve the air supply effect in the cooling mode and the heating mode. In the embodiment in which the indoor air inlet 12 is located between the two indoor air outlets 13, the self-exit air flow is sent out obliquely upward and downward, which can further reduce the direct flow of the air out from the indoor air outlet 13 by the indoor air inlet. The possibility of inhalation of the tuyere 12. Of course, in other embodiments, the extending direction of the air outlet duct 17 may also be perpendicular to the front surface 14 of the inner casing.

In one embodiment, the indoor air duct 11 includes two mutually independent sub-air ducts, each of which is provided with a fan wheel, and the inner casing 10 is provided with two indoor air inlets 12; one of the indoor air outlets 13 It is connected with one indoor air inlet 12 to one of the sub-air ducts, and the other indoor air outlet 13 and the other indoor air inlet 12 are connected to another sub-air duct. In this way, it is possible to ensure that the two wind wheels are independent of each other, thereby ensuring that the intake air flow of the two wind wheels is independent of each other in the inner casing 10, so as to prevent the negative pressure generated by one of the wind wheels from being too large and causing the other wind wheel to reduce the intake air flow. Case. Therefore, it is convenient to independently adjust the air outlet speed of the two wind rotors, so as to realize the air supply of different speeds and different air volumes to two different areas at the same time, and to realize various air outlet modes to meet different air supply requirements. Wherein, the indoor air outlets 13 of the two sub-air ducts can both be arranged on the front side 14 of the inner shell, or can be arranged on the side 15 of the same inner shell, or the indoor air outlets 13 of the two sub-air ducts can be arranged on the side surfaces 15 of the two inner shells, respectively. Alternatively, the indoor air outlet 13 of one of the sub-air ducts is arranged on the front surface 14 of the inner casing, and the indoor air outlet 13 of the other sub-air duct is arranged on the side surface 15 of the inner casing.

In one embodiment, the two impellers are of the same type. It should be noted that the size and electrical parameters of the two wind rotors are not limited to be exactly the same, and the two wind rotors can have the same type of air in and out. For example, both wind rotors are cross-flow wind rotors, or both are Centrifugal wind wheel, or mixed flow wind wheel and so on. By using the same type of wind wheel, the types of materials of the integrated air conditioner can be reduced, so as to facilitate the assembly and material management of the integrated air conditioner, and help reduce the production cost of the integrated air conditioner.

Referring to FIG. 2 , in one embodiment, the two wind wheels are the first cross-flow wind wheels 21 . This arrangement not only increases the overall air supply volume of the integral type air conditioner, but also improves the air supply uniformity. Of course, in other embodiments, the two wind rotors may also be of other types. For example, please refer to FIG. 3 or FIG. 4. In one embodiment, the two wind rotors may also be centrifugal wind rotors. As the power source of the integral air conditioner, the wheel can increase the air supply distance of the integral air conditioner, which is convenient for use in spaces such as prefab houses or container houses.

Moreover, when the indoor air outlet 13 is arranged on the front surface 14 of the inner casing, the air outlet side of the first cross-flow fan wheel 21 can be arranged to face the indoor air outlet 13, so that the air flow can be directly sent out from the indoor air outlet 13, reducing the The loss of wind speed is beneficial to increase the air supply distance. In addition, when the indoor air inlet 12 is arranged on the front surface 14 of the inner shell, the distance between the first cross-flow fan wheel 21 and the indoor air inlet 12 can also be reduced, which is beneficial to shorten the path of the indoor air duct 11 . Of course, in other embodiments, the axis of the first cross-flow impeller 21 may also extend in the front-rear direction.

Referring to FIGS. 1 and 2 , in one embodiment, there is one indoor air inlet 12 , and the air inlet sides of the two first cross-flow fans 21 are both connected to the indoor air inlet 12 . That is to say, the air inlet sides of the two first cross-flow fans 21 share one indoor air inlet 12. This arrangement can reduce the number of indoor air inlets 12 on the inner casing 10, which is beneficial to simplify the structure of the inner casing 10 and reduce the Cost of production. Of course, in other embodiments, a plurality of indoor air inlets 12 may also be provided, and the plurality of indoor air inlets 12 are all communicated with the two first cross-flow wind wheels 21 .

Please refer to FIG. 3 , FIG. 4 or FIG. 6 , in one embodiment, an indoor side heat exchanger 30 is provided inside the indoor air inlet 12 , that is, after the indoor air enters the indoor air duct 11 from the indoor air inlet 12 , it first passes through the indoor side heat exchanger 30 . The heat exchanger 30 performs heat exchange, and the heat-exchanged air is then sucked in by the two wind turbines and sent out respectively by the two wind turbines. In this way, the two wind rotors share one indoor side heat exchanger 30, which can reduce the number of indoor side heat exchangers 30, and also reduce the assembly process of the indoor heat exchanger, which is beneficial to reduce the production cost.

In the embodiment in which the wind rotor is the first cross-flow wind wheel 21 and the axis of the first cross-flow wind wheel 21 extends in the left-right direction, the air outlet duct 17 is opposite to and parallel to the axis of the first cross-flow wind wheel 21 . The spacing between the air duct walls gradually increases in the air outlet direction, so as to better match the air outlet side of the first cross-flow wind wheel 21, thereby better increasing the air supply range. Of course, in other embodiments, the dimensions of all parts of the air outlet duct 17 may be approximately the same.

Referring to FIG. 3 or FIG. 4 , when the wind wheel is the centrifugal wind wheel 22 , in one embodiment, the air inlet side of the centrifugal wind wheel 22 is disposed toward the indoor air inlet 12 . That is, the position of the inner casing 10 facing the air inlet side of the centrifugal wind wheel 22 is provided with the indoor air inlet 12, so that the distance between the air inlet side of the centrifugal wind wheel 22 and the indoor air inlet 12 is small, which is beneficial to shorten the air inlet. Path and shorten the air duct path between the indoor air inlet 12 and the indoor air outlet 13 . Of course, in other embodiments, the indoor air inlet 12 and the air inlet side of the centrifugal wind wheel 22 may also be arranged at intervals in the vertical direction.

That is, after the indoor air enters the indoor air duct 11 from the indoor air inlet 12, it first passes through the indoor side heat exchanger 30 for heat exchange. The air entering the tuyere 12 can pass through the indoor side heat exchanger 30 to improve the heat exchange efficiency. Moreover, the heat-exchanged airflow can quickly enter the centrifugal wind wheel 22 and be sent out from the indoor air outlet 13, shortening the air supply path of the heat-exchanged airflow, thereby reducing the energy loss of the heat-exchanged airflow. In addition, the wind resistance at the indoor air outlet 13 can be reduced to ensure a large air outlet speed and a long air supply distance, and also reduce the accumulation of dust on the inner side of the indoor side heat exchanger 30 . Of course, in other embodiments, the indoor side heat exchanger 30 may also be provided between the indoor air outlet 13 and the air outlet side of the centrifugal wind rotor 22 .

There are various ways of installing the centrifugal wind wheel 22. For example, please refer to FIG. 3 or FIG. 6. In one embodiment, the axis of the centrifugal wind wheel 22 extends in the front-rear direction. That is to say, the air inlet side of the centrifugal fan wheel 22 is disposed toward the front side or the rear side of the inner casing 10, so that the space in the left-right direction and the up-down direction in the inner casing 10 can be fully utilized, so that the radial direction of the centrifugal fan wheel 22 can be fully utilized. The size is larger, so as to increase the air supply volume of the centrifugal fan wheel 22 . At the same time, the axial dimension of the centrifugal fan 22 is small, which can reduce the dimension of the inner casing 10 in the front-rear direction. In the embodiment in which the air inlet side of the centrifugal rotor 22 is disposed toward the indoor air inlet 12 , that is, the indoor air inlet 12 may be disposed on the front surface 14 of the inner casing (refer to the structure of the inner casing 10 in FIG. 1 or FIG. 5 ) or inside the inner casing 14 The back surface 16 of the housing, in this embodiment, the indoor air outlet 13 is provided on the front surface 14 of the inner housing. Of course, in other embodiments, when the axis of the centrifugal wind wheel 22 extends in the front-rear direction, the indoor air inlet 12 may also be provided on the side surface 15 of the inner casing.

In addition, please refer to FIG. 4 or FIG. 8 , in another embodiment, the axis of the centrifugal wind wheel 22 extends along the left-right direction. That is to say, the air inlet side of the centrifugal fan wheel 22 is set to the left or right side of the inner casing 10. It should be understood that the air inlet side of the centrifugal fan wheel 22 is located on the axial side, and the air outlet side of the centrifugal fan wheel 22 is located on the axial side. Therefore, when it is set in this way, the air outlet side of the centrifugal fan wheel 22 can be directed to the indoor air outlet 13 of the front surface 14 of the inner casing, so that the airflow sent from the air outlet side of the centrifugal fan wheel 22 can be directly sent out from the indoor air outlet 13, It reduces the situation that the outlet airflow is sent and turned from the outlet side of the centrifugal rotor 22, thereby reducing the excessive energy loss of the outlet airflow due to the change of the airflow direction between the outlet side of the centrifugal rotor 22 and the indoor air outlet 13. It is beneficial to increase the air supply distance. In the embodiment in which the air inlet side of the centrifugal wind wheel 22 is arranged toward the indoor air inlet 12 , that is, the indoor air inlet 12 is arranged on the side surface 15 of the inner casing.

That is to say, the orthographic projection of the centrifugal fan 22 on the front surface 14 of the inner casing is spaced apart from the indoor air inlet 12. In this way, when the indoor side heat exchanger 30 is provided on the inner side of the indoor air inlet 12, the indoor side heat exchanger 30 is also connected to the centrifugal fan. The dislocation of the wheels 22 in the front-rear direction can prevent the indoor heat exchanger 30 and the centrifugal fan 22 from sharing the space in the front-rear direction of the inner casing 10, and can reduce the size of the inner casing 10 in the front-rear direction.

That is, the axis of the centrifugal wind wheel 22 extends in the left-right direction, and the two opposite sides of the centrifugal wind wheel 22 are formed with air inlet sides, which can reduce the air flow on the air outlet side of the centrifugal wind wheel 22 and the indoor air outlet 13. In the case of excessive energy loss due to the change of the airflow direction, the air inlet and outlet air volumes of the centrifugal wind wheel 22 can also be increased. In this embodiment, the indoor air inlet 12 can be provided on the front side 14 of the inner casing, or can be provided on the side surface 15 of the inner casing. Referring to FIG. 4 , in the embodiment in which two centrifugal rotors 22 are provided, the indoor air inlet 12 on the side surface 15 of the inner casing is in the shape of a long strip extending in the up-down direction, so that the two centrifugal rotors 22 can enter the air on the same side. The side shares an indoor air inlet 12 . Of course, in other embodiments, two centrifugal impellers 22 may also be provided, the axes of the two centrifugal impellers 22 are approximately coaxial and both extend in the left-right direction, and the air inlet sides of the two centrifugal impellers 22 are arranged away from each other.

In one embodiment, the two rotors include a first rotor and a second rotor, and the first rotor and the second rotor are of different types. The different types of the first wind wheel and the second wind wheel refer to the different types of wind entering and leaving the first wind wheel and the second wind wheel.

In this way, when the air is supplied by the first cross-flow fan wheel 21, the first cross-flow fan wheel 21 can ensure that the air supply is uniform, and can better meet the user's requirements for the uniformity of the air supply. When the air is supplied by the centrifugal wind wheel 22, the air supply distance of the centrifugal wind wheel 22 can be ensured to be relatively long. Moreover, the centrifugal wind wheel 22 runs smoothly and can reduce noise. When used in a prefab house or a container house, it can reduce the vibration of the integral air conditioner, thereby reducing the noise caused by the mutual vibration and friction between the integral air conditioner and the wall. On the other hand, when the air is supplied by the first cross-flow fan rotor 21 and the centrifugal fan rotor 22 at the same time, the air supply uniformity and the air supply distance can be achieved.

That is, the centrifugal fan 22 is arranged below the first cross-flow fan 21, so that in the cooling mode, the first cross-flow fan 21 can be used for main air supply, thereby ensuring the uniformity of cold airflow. In the heating mode, the centrifugal fan wheel 22 can be used for the main air supply to ensure that the air supply distance of the hot air flow is relatively long. In addition, in another embodiment, the centrifugal impeller 22 is located above the first cross-flow impeller 21 . That is, the first cross-flow fan wheel 21 is arranged below the centrifugal fan wheel 22, so that in the cooling mode, the centrifugal fan wheel 22 can be used for main air supply, so as to ensure a longer air supply distance of the cold airflow. While in the heating mode, the first cross-flow fan wheel 21 can be used for the main air supply to ensure the uniformity of the hot air flow.

The shape of a long strip can increase the air supply range of the integral type air conditioner in the vertical direction.

In another embodiment, the axis of the first cross-flow fan wheel 21 extends laterally. It should be noted that the "horizontal" refers to the horizontal direction or substantially horizontal direction when the integral air conditioner is placed and operated. In this way, the indoor air outlet 13 can be set at a higher position of the inner casing 10. In the cooling mode, since the cold air will flow downward after being sent out from the indoor air outlet 13, the indoor air outlet 13 is set on the inner casing 10. When the position is higher, the cold air can be sent from the top as much as possible, so that the cold air can be better distributed in the room. It is also possible to set the indoor air outlet 13 at a lower position of the inner casing 10. In the heating mode, since the hot air will flow upward after being sent out from the indoor air outlet 13, the indoor air outlet 13 is set to the inner casing 10.

In this way, when the indoor side heat exchanger 30 is provided on the inner side of the indoor air inlet 12, the indoor side heat exchanger 30 and the centrifugal fan rotor 22 are also spaced apart in the vertical direction, so that the indoor side heat exchanger 30 and the centrifugal fan rotor 22 can be avoided. When the space in the front-rear direction of the inner casing 10 is shared, the size of the inner casing 10 in the front-rear direction can be reduced.

Referring to FIG. 9 , in another embodiment, the first wind wheel is a centrifugal wind wheel 22 , and the second wind wheel is an axial flow wind wheel 23 . In this way, when the integrated air conditioner is used, if a large amount of air is required for air supply, the main air supply can be performed by the axial flow fan 23 . When the air needs to be sent to a distance, the centrifugal wind wheel 22 can be used for the main air supply, so that the air flow can be sent to a distant location. In addition, the centrifugal fan wheel 22 and the axial flow fan wheel 23 can also be activated to supply air at the same time, so as to meet the demand for air supply with a large air volume, and also meet the demand for long-distance air supply. In this way, the integral air conditioner can realize various air supply modes, which increases the diversity of air supply modes, and makes the application scenarios of the integral air conditioner wider. Moreover, the centrifugal wind wheel 22 runs smoothly and can reduce noise. When used in a prefab house or a container house, it can reduce the vibration of the integral air conditioner, thereby reducing the noise caused by the mutual vibration and friction between the integral air conditioner and the wall.

The casing 40 is connected to the back surface 16 of the inner casing 10 , and the compressor 50 is arranged in the inner casing 10 . The compressor 50 is connected to the indoor side heat exchanger 30 through a refrigerant line. It should be noted that the "inner casing 10" and "outer casing 40" in the embodiments of the present application do not limit the installation positions of the inner casing 10 and the outer casing 40, and the integral air conditioner can be integrated as a whole. Installed indoors, at this time, both the inner casing 10 and the outer casing 40 are installed indoors. Alternatively, the inner casing 10 may be installed indoors, and the outer casing 40 may be at least partially extended to the outdoors. In order to make the outer unit casing 40 protrude toward the outdoors, an installation opening is usually provided on the wall, so that the outer unit casing 40 can protrude from the installation opening toward the outdoors. In this case, the inner surface of the wall and the wall This part of the space (installation opening) between the external surfaces is regarded as outdoor, that is, the space inside the inner surface of the wall can be regarded as indoor, and the space outside the inner surface of the wall can be regarded as outdoor.

However, by arranging the compressor 50 in the inner casing 10, the overall weight of the outer casing 40 is reduced, so that when the outer casing 40 is installed on a floor above the second floor of the house, the outer casing can be reduced in size The pressure of the casing 40 on the support frame. For example, when the integral air conditioner is used in a prefab house (container house) with two or more floors, installing the outer casing 40 outdoors can reduce the pressure on the support frame, while the outer casing 40 is connected to the outside. When the inner casing 10 is connected, the outer casing 40 may not even be supported by a support frame, which can be conveniently used in a prefab house or a container house.
