  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of an integrated air conditioner according to an embodiment of the present invention.

  As shown in FIG. 1, the integrated air conditioner 10 is configured to air-condition the room in a state of being arranged outside the room. Although details will be described later, the integrated air conditioner 10 is installed outside in a state of approaching the outer side surface W1 of the wall W of a building such as a residence that separates the outside from the room.

  FIG. 2 is a cross-sectional view schematically showing the internal configuration of the integrated air conditioner 10 as viewed from the front side of the integrated air conditioner 10, and FIG. 3 schematically shows the internal configuration of the integrated air conditioner 10. FIG. 4 is a cross-sectional view seen from the side of the integrated air conditioner 10 shown, and FIG. 4 is a cross-sectional view parallel to the horizontal plane of the integrated air conditioner 10 and taken along the line GG in FIG. is there. 5 is a cross section parallel to the horizontal plane of the integrated air conditioner 10, and is a cross sectional view along the line HH in FIG.

  In the present specification, the “front side” of the integrated air conditioner 10 refers to the integrated air conditioner 10 and the wall W in the facing direction (X-axis direction) between the integrated air conditioner 10 and the wall W. The part of the integrated air conditioner 10 (the part of the casing 12) that can be seen sometimes is said. On the other hand, the “rear side” of the integrated air conditioner 10 is not visible when the integrated air conditioner 10 and the wall W are viewed in the facing direction (X-axis direction) between the integrated air conditioner 10 and the wall W. The part of the integrated air conditioner 10 (the part of the casing 12) is said. In the following, the integrated air conditioner 10 is omitted and referred to as an “air conditioner 10”.

  The air conditioner 10 of this Embodiment has the substantially rectangular parallelepiped housing | casing 12 large in a perpendicular direction (Z-axis direction), as shown in FIG.

  The casing 12 includes a back surface 12a that faces the outer surface W1 of the wall W when the air conditioner 10 is installed outdoors, and a front surface 12b that is parallel to the back surface 12a. The left side surface 12c and the right side surface 12d located between 12b and the back surface 12a are provided.

  In the case of such a substantially rectangular parallelepiped housing 12, the front surface 12b corresponds to the “front side” of the air conditioner 10, and the back surface 12a, the left side surface 12c, and the right side surface 12d are on the “rear side” of the air conditioner 10. Equivalent to. That is, when the air conditioner 10 and the wall W are viewed in the opposite direction (X-axis direction) between the air conditioner 10 and the wall W, the front surface 12b of the housing 12 is visible, but the remaining back surface 12a and left side surface 12c. And the right side surface 12d are not visible.

  Also, the housing 12 has an outside air intake port 12e for taking in the outside air A1 into the housing 12, and an outside air outlet port 12f for discharging the outside air A1 taken into the housing 12 to the outside of the housing 12. And are formed.

  Further, the casing 12 has an indoor air inlet 12g for sucking the indoor air A2 into the casing 12, and an indoor air for blowing out the indoor air A2 sucked into the casing 12 to the outside of the casing 12. A blowout port 12h is formed.

  In the case of the present embodiment, the outside air intake port 12e and the outside air discharge port 12f are configured by arranging a plurality of slot-like openings in the vertical direction (Z-axis direction) and the horizontal direction (X-axis direction, Y-axis direction). ing. The outside air intake port 12e is formed on each of the left side surface 12c and the back surface 12a. On the other hand, the outside air discharge port 12f is formed at the corner between the back surface 12a and the right side surface 12d. Therefore, when the air conditioner 10 and the wall W are viewed in the opposite direction (X-axis direction) between the air conditioner 10 and the wall W, the outside air intake port 12e and the outside air discharge port 12f are not visually recognized.

  In the case of the present embodiment, the indoor air inlet 12g and the indoor air outlet 12h are rectangular openings that are long in the vertical direction (Z-axis direction). It is formed in a state of being aligned in the (Y-axis direction).

  Furthermore, in the case of the present embodiment, the indoor air inlet 12g is located on the right side 12d side with respect to the indoor air outlet 12h. Therefore, when the air conditioners 10 and W are viewed in the opposite direction (X-axis direction) between the air conditioner 10 and the wall W, the indoor air inlet 12g and the indoor air outlet 12h are not visually recognized.

  As shown in FIG. 2 and FIG. 3, the air conditioner 10 generally includes an outdoor air heat exchange unit 10A for exchanging heat with the outdoor air A1, an indoor air heat exchange unit 10B for exchanging heat with the indoor air A2, It is composed of a ventilation unit 10C for ventilating the room, and a housing unit 10D that houses the control board 14, the compressor 16, and the like.

  Inside the outside air heat exchanging portion 10A of the air conditioner 10, the outside air heat exchanger 18 for exchanging heat with the outside air A1, the outside air intake port 12e, the outside air heat exchanger 18, and the outside air discharge port 12f are arranged in this order. And a cross flow fan 20 that generates a flow of air.

  The indoor air heat exchange unit 10B of the air conditioner 10 is located above the outdoor air heat exchange unit 10A of the air conditioner 10. In addition, the indoor air A2 flows in the order of the indoor air heat exchanger 22 that exchanges heat with the indoor air A2, the indoor air suction port 12g, the indoor air heat exchanger 22, and the indoor air outlet 12h. A cross flow fan 24 for generating a flow is disposed.

  As shown in FIG. 4, the outside air heat exchanger 18 is provided along the plurality of outside air intake ports 12e. The outdoor air heat exchanger 18 is thermally connected to the compressor 16 and the indoor air heat exchanger 22 via a refrigerant pipe (not shown) and a four-way valve (not shown). That is, a refrigeration cycle is configured in which the refrigerant flows through the compressor 16, the four-way valve, the outdoor air heat exchanger 18, the indoor air heat exchanger 22, and the refrigerant pipe connecting them.

  As shown in FIGS. 2 and 3, the cross flow fan 20 is driven by a motor 26 so as to rotate about a rotation center line C1 extending in the vertical direction (Z-axis direction). In addition, the motor 26 is arrange | positioned in the accommodating part 10D, as shown in FIG. Moreover, it arrange | positions so that it may rank with a horizontal direction (X-axis direction and Y-axis direction) with respect to the compressor 16 in accommodating part 10D. Thereby, compared with the case where the motor 26 is arrange | positioned above the compressor 16, the size of the vertical direction (Z-axis direction) of the air conditioner 10 (housing | casing 12) is made small.

  The cross flow fan 20 is disposed in the housing 12 (outside air heat exchanging portion 10A) so as to face the plurality of outside air intake ports 12e with the outside air heat exchanger 18 interposed therebetween.

  As a result, when the cross flow fan 20 is rotated by the motor 26, the outside air A1 passes through the plurality of outside air intake ports 12e formed on the back surface 12a and the left side surface 12c of the housing 12 (the outside air heat exchange unit 10A). Inside) and passes through the heat exchanger 18 for outside air. As a result, the outside air A1 exchanges heat with the outside air heat exchanger 18.

  The outside air A1 after the heat exchange that has passed through the outside air heat exchanger 18 is taken into the cross flow fan 20 and passes through the outside air outlet 12f formed at the corner between the back surface 12a and the right side surface 12d of the housing 12. Through the casing 12.

  In the case of the present embodiment, when the air conditioner 10 is installed so that the back surface 12a of the housing 12 faces the outer surface W1 of the wall W substantially in parallel and at a distance, the outer surface of the wall W The outside air discharge port 12f is configured to discharge the outside air A1 after heat exchange in a direction intersecting W1. According to the outside air discharge port 12f of the present embodiment, as shown in FIG. 4, the outside air A1 discharged from the outside air discharge port 12f is directed to the outside surface W1 in a direction intersecting the outside surface W1 of the wall W. Flowing. Then, the outside air A1 flows along the outer surface W1 in the direction opposite to the facing region between the back surface 12a of the housing 12 and the outer surface W1 of the wall W.

  By using the outer side surface W1 of the wall W in this way, the outside air A1 after heat exchange is directly taken into the housing 12 through the outside air intake port 12e formed on the back surface 12a of the housing 12. It is suppressed. As a result, a decrease in air conditioning efficiency (heat exchange efficiency) of the air conditioner 12 is suppressed.

  Note that one of the reasons for using the crossflow fan 20 that rotates about the rotation center line C1 extending in the vertical direction (Z-axis direction) as the outside air fan for taking the outside air A1 into the housing 12 is as follows. This is because the installation area of the housing 12 can be reduced as compared with the case where a propeller fan is used. Another reason is that when the propeller fan is used as an outside air fan, it is necessary to provide a circular outside air intake port, and the circular outside air intake port greatly impairs the design of the building.

  Further, as shown in FIG. 6, the outside air intake port 12f takes in outside air so that the outside air A1 after heat exchange discharged from the outside air outlet port 12f is not taken into the housing 12 again through the outside air inlet port 12e. A blocking wall portion 12j that blocks the flow of outside air A1 to the mouth 12e may be provided.

  For example, a blocking wall portion 12j protruding toward the outside of the housing 12 is provided in a portion of the housing 12 between the outside air discharge port 12f and the outside air intake port 12e on the back surface 12a of the housing 12. When the air conditioner 10 is installed along the wall W, the blocking wall portion 12j cooperates with the outer side surface W1 of the wall W, so that the outside air directly directed from the outside air discharge port 12 to the outside air intake port 12e. The flow of A1 can be cut off. Thereby, the outside air A1 after heat exchange discharged from the outside air outlet 12f is further suppressed from being directly taken into the housing 12 through the outside air inlet 12e (when there is no blocking wall portion 12j). Compared to). As a result, a decrease in the air conditioning efficiency of the air conditioner 10 can be further suppressed. The blocking wall portion 12j may be formed integrally with the housing 12 or may be configured separately from the housing 12.

  Furthermore, the outside air discharge port 12f is formed only on the right side surface 12d of the housing 12, and the outside air A1 after heat exchange is discharged in a direction parallel to the outer wall surface W1 of the wall W (Y-axis direction). May be. Such an outside air discharge port 12f also prevents the outside air A1 after heat exchange from being directly taken into the housing 12 through the outside air intake port 12e formed on the back surface 12a of the housing 12. it can.

  As shown in FIGS. 2, 3, and 5, the indoor air heat exchanger 10 </ b> B of the air conditioner 10 includes an indoor air inlet 12 g and an indoor air outlet 12 h formed on the back surface 12 a of the housing 12. Is formed. The indoor air heat exchanger 22 and the cross flow fan 24 are disposed in the internal flow path 28. The indoor air A2 flows in the internal flow path 28 from the air suction port 12g toward the air blowing port 12h.

  In the case of the present embodiment, the cross flow fan 24 is driven by the motor 30 so as to rotate around the rotation center line C2 extending in the vertical direction (Z-axis direction). The indoor air heat exchanger 22 is disposed upstream of the cross flow fan 24 in the flow direction of the indoor air A2.

  Below the indoor air heat exchanger 22, there is provided a water tray (not shown) that receives condensed water falling from the indoor air heat exchanger 22. The water collected in the water tray is drained outside the housing 12 through a drainage path (not shown). In addition, you may make it spray the water collected on the water receiving tray on the surface of the heat exchanger 18 for external air through a drainage path. In the case of the first embodiment, since the outdoor air heat exchanger 18 is provided directly above the indoor air heat exchanger 22, the surface of the outdoor air heat exchanger 18 is caused by gravity through a short drainage path. Can lead to.

  When the cross flow fan 24 is rotated by the motor 30, the indoor air A2 flows into the internal flow path 28 of the indoor air heat exchanger 10B via the indoor air suction port 12g. The indoor air A2 that has flowed into the internal flow path 28 passes through the indoor air heat exchanger 22. As a result, the indoor air A2 exchanges heat with the indoor air heat exchanger 22. The room air A2 exchanged with the room air heat exchanger 22 is taken into the cross flow fan 24 and blown out into the room through the room air outlet 12h. Thereby, the room is air-conditioned by the air conditioner 10.

  The indoor air inlet 12g and the indoor air outlet 12h of the air conditioner 10 are communicated with the room via a connecting portion 40 and a flow path structure 42 as shown in FIG.

  The connection part 40 is arrange | positioned between the back surface 12a of the housing | casing 12 of the air conditioner 10, and the outer surface W1 of the wall W, as shown in FIG.1, FIG3 and FIG.5.

  The connecting portion 40 also has a rectangular parallelepiped shape, and communicates with an indoor air suction port 12g formed on the back surface 12a of the housing 12 and a suction hole 42a penetrating the wall W from the outdoor side toward the indoor side. The internal flow path 40a for suction is provided.

  The connecting portion 40 further includes a blowout internal flow path 40b that connects the indoor air blowout opening 12h of the housing 12 and a blowout hole 42b that penetrates the wall W from the outside toward the inside of the room.

  By the connecting portion 40 integrally including an internal flow passage 40a for sucking the indoor air A2 into the housing 12 and an internal flow passage 40b for blowing the indoor air A2 after heat exchange into the room, It is suppressed that the design of the building including the wall W is impaired (that is, the duct (flow path) connecting the indoor air suction port 12g and the suction hole 42a and the indoor air outlet 12h and the blow hole 42b are connected). Compared to the case where the ducts (flow paths) are configured separately).

  In the case of the present embodiment, as shown in FIG. 5, the connecting portion 40 is disposed between the back surface 12a of the housing 12 and the outer surface W1 of the wall W, so that the air conditioner 10 and the wall W When the air conditioner 10 and the wall W are viewed in the opposite direction (X-axis direction), the connecting portion 40 is not visually recognized.

  By such a connection part 40, it is suppressed that the wall W and the air conditioner 10 harmonize with a design, and the design property of buildings, such as a residence, is impaired.

  In this embodiment, the suction hole 42a and the blow hole 42b connected to the suction internal flow path 40a and the blow internal flow path 40b of the connecting portion 40 are not directly formed in the wall W. . The suction hole 42 a and the blowout hole 42 b are fitted in the wall W and are formed in the flow channel structure 42 that constitutes a part of the wall W.

  In the case of the present embodiment, the flow channel structure 42 is attached in the shape of a through hole having a rectangular cross section formed on the wall W so as to communicate the outdoor and indoors as shown in FIGS. A rectangular parallelepiped main body portion 42c inserted through the hole W3 and a decorative panel 42d attached to the inner side surface W2 of the wall W are provided.

  The suction hole 42a and the blow-out hole 42b pass through the main body 42c and the decorative panel 42d, thereby connecting the outside and the room.

  The main body portion 42c of the flow path structure 42 is box-shaped and has a heat insulating material therein. The suction hole 42a and the blowing hole 42b are formed so as to penetrate the heat insulating material.

  For example, in consideration of pressure loss, air conditioning efficiency, and the like, the cross-sectional shape of the suction hole 42a changes from the outdoor side toward the indoor side in the main body 42c of the flow path structure 42. Or, in order to match the opening on the indoor side of the suction hole 42 with the design of the room, the cross-sectional shape of the suction hole 42 changes from the outdoor side toward the indoor side.

  That is, the suction hole 42a extends from the outdoor side to the indoor side while the aspect ratio (vertical (Z-axis direction size) / horizontal (Y-axis direction size)) of the rectangular cross section changes.

  Note that, instead of or in addition to the suction hole 42a, the blowout hole 42b may also extend from the outdoor to the indoor while the aspect ratio of the rectangular cross section changes.

  The decorative panel 42d of the flow path structure 42 is attached to the inner side surface W2 of the wall W and covers the gap between the main body portion 42c and the attachment hole W3 of the wall W. The decorative panel 42d is provided with an operation unit (not shown) such as a switch for the user to operate the air conditioner 10. Or the light-receiving part which light-receives the signal radiate | emitted from the remote controller for operating the air conditioner 10 remotely, for example, an infrared signal, is provided. The operation unit provided on the decorative panel 42 d is electrically connected to the control board 14 in the housing 12 via the flow channel structure 42 and the coupling unit 40.

  According to such a flow path structure 42, the construction of the air conditioner 10 is facilitated as compared with the case where the suction holes 42a and the blowout holes 42b are each formed directly in the wall W. In particular, when the cross-sectional shape of the suction hole 42 and the blowout hole 42b changes from the outside to the room as in the present embodiment, the construction of the air conditioner 10 is particularly easy.

  Further, as shown in FIG. 1, the flow path structure 42 is fitted into the wall W so as to face the back surface 12 a of the housing 12, so that the air conditioner 10 and the wall W are opposed to each other (X-axis direction). When the air conditioner 10 and the wall W are viewed, the flow path structure 42 is not visually recognized. By such a flow path structure 42, it is suppressed that the design property of buildings, such as a residence provided with the wall W, is impaired.

  As shown in FIGS. 2, 3, and 8, in the present embodiment, in the air conditioner 10, the ventilation unit 10 </ b> C is disposed at the top.

  The ventilation unit 10C of the air conditioner 10 is configured to ventilate the room by supplying the outside air A1 to the room and discharging the room air A2 to the outside. For this purpose, the ventilating unit 10C includes an outside air suction port 50 for sucking the outside air A1, a fan 52 that generates a flow of the outside air A1 from the outside air suction port 50 toward the room, and a room for discharging the room air A2 to the outside. It has an air outlet 54 and a fan 56 that generates a flow of indoor air A2 from the room toward the indoor air outlet 54. In addition, the ventilation unit 10C includes a ventilation heat exchanger 58 for exchanging heat between the outside air A1 supplied to the room and the room air A2 discharged to the outside.

  As shown in FIGS. 2, 3, and 8, the outdoor air suction port 50 and the indoor air discharge port 54 of the ventilation unit 10 </ b> C are arranged in the horizontal direction (Y-axis direction) on the upper portion of the back surface 12 a of the housing 12. It is formed in a state.

  As shown in FIG. 3, a filter 60 such as a high efficiency particulate air (HEPA) filter may be provided in the outside air suction port 50 to suppress entry of particulates into the room.

  As shown in FIGS. 3 and 5, the outdoor air suction port 50 exchanges heat for indoor air in the internal flow path 28 of the indoor air heat exchange section 10 </ b> B via an internal flow path 62 formed in the ventilation section 10 </ b> C. It is connected to the upstream side of the vessel 22. A ventilation heat exchanger 58 and a fan 52 are arranged in this internal flow path 62 in order from the outside air suction port 50 side. In the present embodiment, the fan 52 is a sirocco fan.

  On the other hand, as shown in FIGS. 3, 5, and 8, the indoor air outlet 54 is connected to the internal flow path of the indoor air heat exchange section 10 </ b> B via the internal flow path 64 formed in the ventilation section 10 </ b> C. 28 is connected to the upstream side of the indoor air heat exchanger 22. As shown in FIG. 5, the connection portion between the internal flow path 64 and the internal flow path 28 is connected to the indoor air suction port 12 g of the housing 12 in comparison with the connection portion between the internal flow path 62 and the internal flow path 28. Located close. Further, a ventilation heat exchanger 58 and a fan 56 are arranged in the internal flow path 64 in order from the indoor air discharge port 54. In the present embodiment, the fan 56 is a sirocco fan.

  Furthermore, in the case of the present embodiment, the two sirocco fans 52 and 56 of the ventilation unit 10C are centered on a common rotation center line C3 extending in the facing direction (X-axis direction) between the housing 12 and the wall W. It rotates and is driven by a common motor 66. By driving the two sirocco fans 52 and 56 by one motor 66, one motor can be omitted.

  As shown in FIG. 3, when a filter 60 such as a HEPA filter is provided in the outside air suction port 50, the fan 52 for sucking outside air A <b> 1 is discharged from the room air A <b> 2 in consideration of intake resistance. It is preferable to enlarge the size of the fan 56.

  According to such a ventilating unit 10C of the air conditioner 10, the room can be ventilated while the room is air-conditioned. Note that when only indoor ventilation is performed without air-conditioning the room, the two sirocco fans 52 and 56 and the crossflow fan 24 rotate while the compressor 16 and the crossflow fan 20 are stopped. As a result, as shown in FIG. 3, the indoor air A1 is divided into the suction hole 42a of the flow channel structure 42, the suction flow channel 40a of the connecting portion 40, the internal flow channel 28 of the indoor air heat exchange unit 10B, and the ventilation unit. 10C internal passage 64 (sirocco fan 56 and ventilation heat exchanger 58) and indoor air outlet 54 are sequentially passed through and discharged to the outside. Further, the outside air A1 includes the outside air suction port 50, the internal flow path 62 (ventilation heat exchanger 58 and sirocco fan 52) of the ventilation section 10C, and the internal flow path 28 (heat exchange for room air) of the indoor air heat exchange section 10B. Device 22 and cross flow fan 24), blowout internal flow path 40b of connecting part 40, and blowout hole 42b of flow path structure 42 are sequentially supplied to the room.

  As mentioned above, according to this Embodiment, the installation area of the integrated air conditioner 10 can be made small.

  Specifically, as shown in FIGS. 2 and 3, both the outdoor air fan 20 and the indoor air fan 24 are centered on rotation center lines C1 and C2 extending in the vertical direction (Z-axis direction). It is a cross flow fan that rotates as For example, when a propeller fan is used as a fan for outside air and a fan for room air, the casing of the air conditioner is larger in the horizontal direction than when a cross flow fan is used.

  That is, when rotating at the same rotational speed and delivering the same air volume, the fan diameter of the propeller fan becomes larger than the fan diameter of the cross flow fan. Therefore, when such a propeller fan is housed in the housing, the installation area of the housing is larger than when the cross flow fan is housed in the housing with the rotation center line extending in the vertical direction.

  2 and 3, when the cross flow fans 20 and 24 are housed in the housing 12 with the rotation center lines C1 and C2 extending in the vertical direction (Z-axis direction), the housing Although the installation area of 12 becomes small, the height (size in the vertical direction (Z-axis direction)) becomes large.

  However, when the casing 12 becomes large in the vertical direction (Z-axis direction), the suction holes 42a and the blowout holes 42b formed in the wall W (the flow path structure 42 in the present embodiment) are hidden by the casing 12. It becomes possible. Thereby, the duct (in this embodiment, the suction internal flow path 40a of the connecting portion 40) that connects the indoor air suction port 12g of the housing 12 and the suction hole 42a of the wall W, and the interior of the housing 12 The casing 12 can hide the duct (the internal flow passage 40b for the connection portion 40) connecting the air discharge port 12h and the discharge hole 42b of the wall W. As a result, it is suppressed that the design of buildings, such as a residence provided with the wall W, is impaired by the two ducts extending from the housing 12 toward the wall W.

  In the case of the present embodiment, as shown in FIGS. 2 and 3, the lower end of the crossflow fan 24 for indoor air is positioned above the upper end of the crossflow fan 20 for outside air. As a result, the installation area of the housing 12 can be reduced.

  Unlike this, when the lower end of the cross flow fan 24 is positioned lower than the upper end of the cross flow fan 20 (and when it is positioned higher than the lower end of the cross flow fan 20), that is, When at least a part and at least a part of the cross flow fan 24 overlap in the horizontal direction, a partition wall is required between the two cross flow fans 20 and 24 in the horizontal direction. The partition referred to here is an inner wall formed in the housing 12 in order to isolate the flow of the outside air A1 generated by the crossflow fan 20 from the flow of the indoor air A2 generated by the crossflow fan 24. Due to the presence of the partition wall, when the lower end of the cross flow fan 24 is positioned below the upper end of the cross flow fan 20, the installation area of the housing 12 is increased.

  On the other hand, when the lower end of the cross flow fan 24 is located above the upper end of the cross flow fan 20 as in the present embodiment, a partition is provided between the two cross flow fans 20 and 24 in the vertical direction. become. Thereby, the installation area of the housing | casing 12 becomes small.

  Furthermore, when the lower end of the cross flow fan 24 is positioned above the upper end of the cross flow fan 20, the two cross flow fans 20 and 24 are at least partially connected as viewed in the vertical direction (viewed in the Z-axis direction). It is also possible to overlap. If the two cross flow fans 20 and 24 overlap at least partially when viewed in the vertical direction, the casing 12 is further slimmed down, that is, the installation area of the casing 12 is further reduced as compared with the case where the two do not overlap. Can do.

  Although the present invention has been described with reference to the above-described embodiments, the present invention is not limited to the above-described embodiments.

  For example, in the case of the above-described embodiment, the indoor air inlet 12g of the housing 12 is located on the right side 12d side with respect to the indoor air outlet 12h, but may be reversed. In this case, the suction internal flow path 40a of the connecting portion 40 is positioned on the left side with respect to the blowout internal flow path 40b so as to correspond. Similarly, the suction hole 42a of the flow path structure 42 is located on the left side with respect to the blowing hole 42b.

  Further, for example, in the case of the above-described embodiment, the air conditioner 10 has a substantially rectangular parallelepiped shape that is large in the vertical direction (Z-axis direction), but is not limited thereto. For example, a cylindrical shape may be sufficient.

  Further, for example, in the case of the above-described embodiment, as shown in FIGS. 2 and 3, the lower end of the cross flow fan 24 of the indoor air heat exchange unit 10B is lower than the upper end of the cross flow fan 20 of the outdoor air heat exchange unit 10A. Although located in the upper part, it is not restricted to this. For example, if the installation area of the housing is smaller than the case where a fan having a shape different from the cross flow fan (for example, a propeller fan) is housed in the housing instead of the cross flow fan, at least the cross flow fan 20 A part and at least a part of the cross flow fan 24 may be accommodated in the housing 12 in a state of overlapping in the horizontal direction.

  In this regard, in the case of the above-described embodiment, as shown in FIGS. 2 and 3, the indoor air heat exchange unit 10B is positioned above the outdoor air heat exchange unit 10A. The lower end of the cross flow fan 24 is positioned above the upper end of the cross flow fan 20. Unlike this, when the indoor air heat exchange unit 10B is positioned below the outside air heat exchange unit 10A, the lower end of the cross flow fan 20 is positioned above the upper end of the cross flow fan 24.

Thus, the air conditioner according to the embodiment of the present invention can take various forms. That is, the air conditioner according to the embodiment of the present invention is broadly defined as:
An integrated air conditioner in which a heat exchanger for outside air that exchanges heat with outside air and a heat exchanger for indoor air that exchanges heat with room air are housed in one housing,
An outside air intake port that is formed in the housing and takes in outside air;
An outside air outlet that is formed in the housing and exhausts outside air after heat exchange with the outside air heat exchanger;
A cross flow fan for outside air that generates a flow through which the outside air flows in the order of an outside air intake port, an outside air heat exchanger, and an outside air discharge port, and rotates about a rotation center line extending in the vertical direction;
An indoor air suction port formed in the housing for sucking indoor air;
An indoor air outlet for blowing out indoor air into the room after heat exchange with the heat exchanger for indoor air formed in the housing;
A cross-flow fan for indoor air that generates a flow in which the indoor air flows in the order of the indoor air inlet, the indoor air heat exchanger, and the indoor air outlet, and that rotates about a rotation center line extending in the vertical direction. It is an integrated air conditioner.

  Furthermore, in the case of the above-described embodiment, the air conditioner 10 includes the ventilation unit 10C that ventilates the room, but the ventilation unit 10C may not be provided. In other words, the ventilation unit may be an option that is selectively attached to the air conditioner by the user.

  In addition, in the case of the above-described embodiment, the connecting portion 40 and the flow path structure 42 are separate, but they may be integrated. In this case, since the indoor air A1 does not leak from between the connecting portion 40 and the flow path structure 42, the air conditioning efficiency of the air conditioner 10 is improved.

  In addition, the outside air discharge port 12f may discharge the outside air A1 after heat exchange in the horizontal direction or in the downward direction. Preferably, the outside air discharge port discharges outside air after heat exchange in a downward direction in which outside air after heat exchange does not hit the user's face located in the vicinity of the air conditioner.

  In addition, in the case of the above-described embodiment, the outside air intake port 12e is formed on the back surface 12a and the left side surface 12c of the housing 12, but is not limited thereto. For example, it may be formed on the right side surface of the housing. However, in this case, the outside air discharge port is formed on the left side surface. This is to prevent the outside air after the heat exchange discharged from the outside air outlet from flowing into the outside air intake.

  In addition, in the case of the above-described embodiment, the suction hole 42a and the blowout hole 42b are formed in the flow path structure 42. If each structure is simple (for example, a hole having a constant cross-sectional shape), It may be formed on the wall W.

  The present invention is applicable as long as it is an integrated air conditioner in which a heat exchanger for outside air that exchanges heat with outside air and an indoor heat exchanger that exchanges heat with room air are housed in one housing.
