(Embodiment 1)
FIG. 1 is a perspective view of an integrated air conditioner according to Embodiment 1 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.

  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 visually recognized is sometimes referred to. 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”.

  As shown in FIG. 1, the air conditioner 10 according to the first embodiment includes a substantially rectangular parallelepiped housing 12 that is large in the vertical direction (Z-axis direction).

  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 first embodiment, the outside air intake port 12e and the outside air discharge port 12f are configured by arranging a plurality of slot-shaped openings in the vertical direction (Z-axis direction) and the horizontal direction (X-axis direction, Y-axis direction). Has been. 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. The outside air discharge port 12f may be formed only on the right side surface 12d, not on the corner between the back surface 12a and the right side surface 12d. In this case, a plurality of support columns for improving the structural strength of the housing 12 can be provided at the four corners of the housing 12.

  In the case of the first embodiment, the indoor air inlet 12g and the indoor air outlet 12h are rectangular openings that are long in the horizontal direction (Y-axis direction), and are formed in the vertical direction on the back surface 12a of the housing 12. They are formed in a state of being aligned in the (Z-axis direction). In the case of the first embodiment, the indoor air inlet 12g is located above 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 sirocco 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 FIG. 4, the cross flow fan 20 is driven by a motor 26 so as to rotate about a rotation center line C <b> 1 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. In addition, the control board 14 is arranged on the front surface 12b side from the motor 26 to reduce the size of the air conditioner 10 (housing 12) in the vertical direction (Z-axis direction) and to maintain the control board 14. It is desirable for improving the performance.

  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 first 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 outside 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 the side surface W1.

  Specifically, the outside air discharge port 12f is connected to the outside air intake port 12e so that the outside air A1 after heat exchange discharged from the outside air discharge port 12f is not taken into the housing 12 again through the outside air intake port 12e. On the other hand, the outside air A1 after heat exchange is discharged in a direction away from the outside. According to the outside air discharge port 12f of the first 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 cross flow fan 20 that rotates about the rotation center line C1 extending in the vertical direction (Z-axis direction) as an outside air fan for taking outside air into the housing 12 is used. This means that 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.

  As shown in FIGS. 2 and 3, the indoor air heat exchange unit 10B of the air conditioner 10 communicates with the indoor air suction port 12g formed on the back surface 12a of the housing 12 and the indoor air outlet 12h. A flow path 28 is formed. The indoor air heat exchanger 22 and the sirocco fan 24 are arranged 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 first embodiment, the sirocco fan 24 rotates around a rotation center line C2 extending in the facing direction (X-axis direction) between the air conditioner 10 (housing 12) and the wall W. It is driven by the motor 30. The indoor air heat exchanger 22 is disposed upstream of the sirocco fan 24 in the flow direction of the indoor air A2.

  In the case of the first embodiment, since the rotation axis of the sirocco fan 24 is provided so as to extend in the X-axis direction, compared with the case where the rotation axis is provided so as to extend in the Y-axis direction, The entire area of the indoor air heat exchanger 22 provided to face the side surface (surface perpendicular to the rotation center line C2) of the sirocco fan 24 can be increased. Further, the fan diameter of the sirocco fan 24 can be increased.

  Further, 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 above the indoor air heat exchanger 22, water can be guided to the surface of the outdoor air heat exchanger 18 by gravity.

  When the sirocco 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 through 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 sirocco 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.

  In the case of the first embodiment, the indoor air heat exchanger 22 is disposed on the front surface 12b side of the air conditioner 10 (housing 12) from the sirocco fan 24, and therefore, as shown in FIG. The linear flow path extending in the X direction constituting a part of the path 28 can be lengthened. Thereby, the flow velocity distribution of the air guided to the indoor air heat exchanger 22 can be made uniform through the linear flow path 28a extending in the Z direction constituting a part of the internal flow path 28.

  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 and FIG.

  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 suction internal flow path 40a has a rectangular section that is long in the horizontal direction (Y-axis direction) and is connected to the indoor air suction port 12g, and is opposed to the housing 12 and the wall W (X-axis direction). Extend to.

  The connecting portion 40 further includes a blowout internal flow path 40b that communicates the indoor air blowout opening 12h of the housing 12 and a blowout hole 42a that penetrates the wall W from the outdoor side toward the indoor side. The blowout internal flow path 40b has a rectangular section that is long in the horizontal direction (Y-axis direction) so as to be connected to the indoor air blowout opening 12h located below the indoor air intake opening 12g. It extends downward and parallel to 40b.

  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).

  Further, in the case of the first embodiment, the connecting portion 40 is disposed between the back surface 12a of the housing 12 and the outer surface W1 of the wall W. Therefore, the facing direction (X-axis) between the air conditioner 10 and the wall W When the air conditioner 10 and the wall W are viewed in the 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.

  As shown in FIG. 5, the connecting portion 40 has a quadrangular cross section, and the suction internal flow path 40a and the blowout internal flow path 40b have the same quadrangular flow path cross section and are vertically aligned (Z-axis). The aspect ratio (vertical L / horizontal S) (that is, the size in the Z-axis direction / the size in the Y-axis direction) of the cross section is in the range of about 1-2. preferable.

  A heat insulating material is accommodated inside the connecting portion 40, and the suction internal flow path 40 a and the blowout internal flow path 40 b extend in a state of being aligned in the vertical direction (Z-axis direction) so as to penetrate the heat insulating material. . That is, a heat insulating material is filled between the outer surface of the connecting portion 40, the suction internal flow path 40a, and the blowout internal flow path 40b.

  FIG. 6 shows the pressure loss of the suction internal flow path 40a and the blowout internal flow path 40b with respect to the aspect ratio of the connecting portion 40 having a rectangular cross section. FIG. 7 shows the volume of the heat insulating material with respect to the aspect ratio of the connecting portion 40. FIG. 8 shows the volume of the connecting part 40 with respect to the aspect ratio of the connecting part 40. The volume of the heat insulating material corresponds to the amount of heat insulating material used, and the volume of the connecting portion 40 corresponds to the compactness of the connecting portion 40. Therefore, the one where the volume of a heat insulating material and the volume of the connection part 40 are small is preferable.

The characteristics of the connecting portion 40 with respect to the aspect ratios shown in FIGS. 6 to 8 are that the length of the connecting portion 40 is 1 m, and the air passage area (the cross-sectional area of each of the suction internal flow path 40a and the blowout internal flow path 40b). ) Is 0.01 m ² and the air velocity of the air flowing through each of the suction internal flow path 40a and the blowout internal flow path 40b is 10 m / s.

  As shown in FIGS. 6 to 8, the pressure loss, the volume of the heat insulating material, and the volume of the connecting portion 40 decrease until the aspect ratio of the connecting portion 40 becomes 1. When the aspect ratio becomes larger than 2, the pressure loss, the volume of the heat insulating material, and the volume of the connecting portion 40 increase. Therefore, the aspect ratio of the connecting portion 40 is preferably in the range of about 1 to 2 in which the pressure loss, the volume of the heat insulating material, and the volume of the connecting portion 40 are reduced. According to such an aspect ratio, it is possible to obtain the connecting portion 40 that is compact in size, excellent in heat insulation efficiency, and low in pressure loss. As a result, the air conditioner 10 can obtain high air conditioning efficiency.

  In the case of the first embodiment, the suction hole 42a and the blowout hole 42b connected to the suction internal flow path 40a and the blowout internal flow path 40b of the connecting portion 40 are formed directly on the wall W. Absent. 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 first embodiment, the flow path structure 42 has a through-hole shape having a rectangular cross section formed on the wall W so as to communicate the outdoor and indoors as shown in FIGS. 1 and 9. A rectangular parallelepiped main body portion 42c inserted through the attachment 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.

  Further, in the main body portion 42c of the flow path structure 42, the cross-sectional shapes of the suction hole 42a and the blowing hole 42b change from the outdoor side toward the indoor side.

  Specifically, in the case of the first embodiment, the indoor air inlet 12g and the indoor air outlet 12h of the housing 12 are rectangular openings that are long in the horizontal direction (Y-axis direction), and are vertically Are aligned in the direction (Z-axis direction).

  According to such a flow path structure 42, the air conditioner 10 can be easily implemented as compared with the case where the suction holes 42a and the blowout holes 42b are directly formed in the wall W. In particular, when the cross-sectional shape of the suction hole 42 and the blowout hole 42b changes from the outdoor side to the indoor side as in the first embodiment, the implementation 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 and 3, in the case of the first 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 10, the outside 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. 2 and 3, the outdoor air suction port 50 exchanges heat for indoor air in the internal flow path 28 of the indoor air heat exchange section 10B via an internal flow path 62 formed in the ventilation section 10C. 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 case of the first embodiment, the fan 52 is a sirocco fan.

  On the other hand, as shown in FIGS. 3 and 10, the indoor air discharge port 54 is connected to the indoor air in the internal flow path 28 of the indoor air heat exchange section 10 </ b> B via the internal flow path 64 formed in the ventilation section 10 </ b> C. It is connected to the upstream side of the industrial heat exchanger 22. As shown in FIG. 2, 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 case of the first embodiment, the fan 56 is a sirocco fan.

  In the case of the first embodiment, since the internal flow path 62 and the internal flow path 64 formed in the ventilation unit 10C are connected to the internal flow path 28 on the upstream side of the indoor air heat exchanger 22, Compared with the case where it is connected to the internal flow path 28 on the downstream side of the air heat exchanger 22, the heat exchanged by the indoor air heat exchanger 22 is not exhausted to the outside, which is more efficient. .

  Further, in the case of the first 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. 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. In the case where only indoor ventilation is performed without air conditioning the room, the three sirocco fans 24, 52, and 56 are rotated while the compressor 16 and the cross flow 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 sirocco fan 24), blowing internal flow path 40b of connecting portion 40, and blowing hole 42b of flow path structure 42 are sequentially supplied to the room.

  In the case of the first embodiment, the ventilation section 10C having the internal flow path 64 on the lower side is provided above the indoor air heat exchange section 10B having the internal flow path 28 on the upper side. Since the internal flow path 28 can be used without separately providing a flow path for guiding the emitted air to the indoor air outlet 12h, the vertical direction (Z-axis direction) of the air conditioner 10 (housing 12). Can be reduced in size.

  In addition, the air conditioner 10 of the first embodiment is configured such that the vertical direction (Z-axis direction) positions of the indoor air inlet 12g and the indoor air outlet 12h can be changed.

  Due to structural limitations of a building such as a residence and / or user preference, the attachment position of the flow path structure 42 to the wall W in the vertical direction (Z-axis direction), that is, the suction hole 42a and the blowout of the flow path structure 42 The position in the vertical direction of the opening on the indoor side of each hole 42b can take various positions.

  As a countermeasure, the housing 12 of the air conditioner 10 according to the first embodiment is configured to be splittable in the vertical direction as shown in FIGS. 11 and 12.

  Specifically, in the case of the first embodiment, the housing 12 is configured to be divided into an upper unit 12i and a lower unit 12j. The upper unit 12i includes an indoor air inlet 12g and an indoor air outlet 12h. On the other hand, the lower unit 12j includes an indoor air heat exchanger 22 and a sirocco fan 24.

  Further, between the indoor air suction port 12g and the indoor air heat exchanger 22, there is a linear flow path 28a that forms a part of the internal flow path 28 and extends in the vertical direction (Z-axis direction). However, between the sirocco application 24 and the indoor air outlet 12h, there is a linear flow path 28b that constitutes a part of the internal flow path 28 and extends in the vertical direction. The casing 12 is configured to be divided into an upper unit 12i and a lower unit 12j so as to divide the linear flow paths 28a and 28b.

  An extension unit 12k for aligning the indoor air inlet 12g and the indoor air outlet 12h of the upper unit 12i in the vertical direction (Z-axis direction) is selectively provided between the upper unit 12i and the lower unit 12j. Placed in. If the extension units 12k having various heights are prepared, the indoor air inlet 12g and the indoor air outlet 12h of the upper unit 12i can be aligned at desired vertical positions.

  Alternatively, if the extension unit 12k is made of a heat-insulating material such as foamed polystyrene, and the air conditioner 10 is installed, the extension unit 12k is cut and arranged in accordance with the structural restrictions of the building. The indoor air inlet 12g and the indoor air outlet 12h of the upper unit 12i can be aligned at a desired vertical position. In this case, it is possible to prevent the design from being impaired by providing a separate cover that covers the extension unit 12k.

  The extension unit 12k includes an extension channel 28a3 that communicates a portion 28a1 of the linear channel 28a on the upper unit 12i side and a portion 28a2 of the linear channel 28a on the lower unit 12j side, and the upper unit i side. And an extended channel 28b3 that communicates the portion 28b1 of the linear channel 28b and the portion 28b2 of the linear channel 28b on the lower unit 12j side.

  Due to the extension flow paths 28a3 and 28b3 of the extension unit 12k, even if the extension unit 12k is interposed between the upper unit 12i and the lower unit 12j, the interior air A2 flows from the indoor suction port 12g to the indoor outlet 12h. A flow path 28 is configured.

  In the case of the first embodiment, a ring surrounding the opening on the upper unit 12i side of the extension flow paths 28a3 and 28b3 of the extension unit 12k so that the indoor air A2 does not leak from between the upper unit 12i and the extension unit 12k. -Shaped seal members 70 and 72 are provided in the extension unit 12k. Further, seal members 74 and 76 are provided so as to surround the openings of the straight flow paths 28a and 28b of the lower unit 12j so that the indoor air A2 does not leak from between the extension unit 12k and the lower unit 12j.

  As described above, in the case of the specification in which the extension unit 12k is cut and arranged, it is preferable that the seal members 74 and 76 are provided not on the extension unit 12k but on the upper unit 12i and the lower unit 12j. Moreover, in the case of this Embodiment 1, since it is the structure which can isolate | separate the upper unit 12i from the lower unit 12j, the handling at the time of manufacture of the air conditioner 10 and transportation becomes easy.

  According to this Embodiment 1, it can suppress that the design property of a building is impaired by the air conditioner 10. FIG. That is, since the outside air intake port 12e and the outside air discharge port 12f are formed on the rear side of the housing 12, the connecting portion 40 and the flow path structure 42 are opposed to the back surface 12a of the housing 12 (that is, the housing). 12), the air conditioner 10 can be harmonized in design with the wall W of a building such as a residence. As a result, the air conditioner 10 can prevent the design of the building from being impaired.

(Embodiment 2)
The air conditioner according to Embodiment 2 has substantially the same configuration as that of Embodiment 1 described above. Therefore, the air conditioner according to the second embodiment will be described focusing on the different points. In addition, the same code | symbol is attached | subjected to the component same as Embodiment 1. FIG.

  As shown in FIGS. 13 and 14, indoor air suction port 112g and indoor air outlet 112h in indoor air heat exchange section 110B of air conditioner 110 according to Embodiment 2 are opposed to outer surface W1 of wall W. It is formed not on the back surface 112a of the housing 112 to be formed but on the right side surface 112d. Therefore, the shape of the connecting portion 140 is different from the straight connecting portion 40 of the first embodiment, and is an “L” shape (that is, the “L” -shaped suction internal flow path 140a and the blowing internal flow. Path 140b).

  Thus, even when the flow path structure 42 cannot be disposed so as to face the back surface 112a of the casing 112 of the air conditioner 110 as shown in FIG. 13, the indoor air suction port 112g of the air conditioner 110 and The indoor air outlet 112h can communicate with the suction hole 42a and the outlet hole 42b of the flow path structure 42.

  According to this Embodiment 2, it can suppress that the design property of a building is impaired by the air conditioner 110. FIG. That is, since the outside air intake port 12e and the outside air discharge port 12f are formed on the back side of the housing 12, the air conditioner 110 can be harmonized in design with the wall W of a building such as a residence. As a result, the design of the building is not impaired by the air conditioner 110.

  In the second embodiment, the indoor air suction port 112g and the indoor air outlet 112h are described as being formed on the right side surface 112d, but the same applies to the case where they are formed on the left side surface 12c. The connecting part 140 can be connected to the terminal.

(Embodiment 3)
The air conditioner according to the third embodiment has the same configuration as that of the first embodiment except for the blocking wall portion. Therefore, the blocking wall will be described. In addition, the same code | symbol is attached | subjected to the component same as Embodiment 1. FIG.

  As shown in FIG. 15, in the air conditioner 210 according to the third embodiment, the heat exchanged outside air A1 discharged from the outside air discharge port 12f is again taken into the housing 12 through the outside air intake port 12e. In order to prevent this, there is a blocking wall portion 280 that blocks the flow of the outside air A1 from the outside air discharge port 12f to the outside air intake port 12e.

  For example, a blocking wall portion 280 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 210 is installed along the wall W, the blocking wall portion 280 cooperates with the outer side surface W1 of the wall W, so that the outside air directed directly from the outside air discharge port 12 to the outside air intake port 12e. The flow of A1 can be cut off. This further suppresses the outside air A1 after heat exchange discharged from the outside air outlet 12f from being directly taken into the housing 12 through the outside air inlet 12e (when there is no blocking wall portion 280). Compared to). As a result, a decrease in the air conditioning efficiency of the air conditioner 210 can be further suppressed. The blocking wall 280 may be formed integrally with the housing 12 or may be configured separately from the housing 12.

  According to the third embodiment, it is possible to prevent the design of the building from being damaged by the air conditioner 210 as in the first embodiment.

(Embodiment 4)
The air conditioner according to the fourth embodiment has the same configuration as that of the first embodiment except for the outside air outlet. Therefore, the outside air outlet will be described. In addition, the same code | symbol is attached | subjected to the component same as Embodiment 1. FIG.

  As shown in FIG. 16, the outside air discharge port 312f in the air conditioner 310 according to the fourth embodiment is formed on the right side surface 312d of the housing 312 (unlike the first embodiment, it is formed on the back surface 312a. It has not been). The outside air discharge port 312f is configured to discharge the outside air A1 after heat exchange in a direction (Y-axis direction) parallel to the outer wall surface W1 of the wall W. Such an outside air discharge port 312f also prevents the outside air A1 after heat exchange from being directly taken into the housing 12 through the outside air intake port 312e formed on the back surface 312a of the housing 312. it can.

  According to the fourth embodiment, it is possible to prevent the design of the building from being damaged by the air conditioner 310 as in the first embodiment.

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

  For example, in the case of the above-described embodiment, the fan 24 that forms the flow of the indoor air A2 is a sirocco fan, but is not limited thereto. For example, a propeller fan may be used.

  For example, in the above-described embodiment, the indoor air inlet 12g (112g) of the housing 12 (112) is located above the indoor air outlet 12h (112h), but may be reversed. In this case, the suction internal flow path 40a (140a) of the connecting portion 40 (140) is positioned below the blowing internal flow path 40b (140b) so as to correspond. Similarly, the suction hole 42a of the flow path structure 42 is positioned below the blowing hole 42b.

  However, the indoor air outlet 12h (112h) is located above the indoor air inlet 12g (112g), and the indoor air heat exchanger 22 is compared with the sirocco fan 24 in the front surface 12b ( 112b), the flow path from the fan 24 to the indoor air outlet 12h (112h) and the flow path from the indoor air suction port 12g (112g) to the indoor air heat exchanger 22 are provided in the housing. 12 (112) crossing in a side view (viewed in the Y-axis direction). As a result, the flow path configuration in the housing 12 (112h) becomes complicated. Therefore, as described in the second embodiment, in order to connect the connecting portion 140 to either the right side surface 112d or the left side surface 12c of the housing 112, as described in the above embodiment mode. The indoor air inlet 12g (112g) is preferably located above the indoor air outlet 12h (112h).

  When the indoor air outlet 12h (112h) is positioned above the indoor air inlet 12g (112g), for example, a configuration of an air conditioner 410 shown in FIG. 17 is conceivable.

  An air conditioner 410 shown in FIG. 17 is a modification of the air conditioner 110 according to the second embodiment. Like the second embodiment, the air conditioner 410 has a room air outlet on the right side surface (the back side of the drawing) of the housing 412. 412h and an indoor air inlet 412g.

  In addition, as shown in FIG. 17, the indoor air heat exchanger 22 is disposed closer to the back surface 412 a of the air conditioner 410 (housing 412) than the sirocco fan 24. As a result, the flow path 428d from the sirocco fan 24 to the indoor air outlet 412h and the flow path 428c from the indoor air suction port 412g to the indoor air heat exchanger 22 are viewed in a side view (Y-axis direction). Will not cross). As shown in FIG. 17, a flow path 428c from the sirocco fan 24 to the indoor air outlet 412h is a flow path (from the sirocco fan 52 to the indoor air heat exchanger 22) through which the outside air A1 flows for indoor ventilation. The right side surface (the back side of the drawing) of the housing 412 extends with respect to the channel 462 that faces.

  Further, for example, in the case of the above-described embodiment, the indoor air inlet 12g (112g) and the indoor air outlet 12h (112h) of the housing 12 (112) are aligned in the vertical direction (Z-axis direction). Unlike this, they may be arranged in the horizontal direction (Y-axis direction (X-axis direction)). Further, the suction internal flow path 40a (140a) and the blowout internal flow path 40b (140b) of the connection portion 40 (140) connected to these may be arranged in the horizontal direction instead of the vertical direction. Similarly, the suction holes 42a and the blowing holes 42b of the flow path structure 42 may be arranged in the horizontal direction instead of the vertical direction.

  Further, for example, in the case of the above-described embodiment, the air conditioner 10 (110, 210, 310) 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.

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 that is arranged in a state of being close to and spaced from a wall having a suction hole and a blowout hole that communicate between the room and the outside,
A housing,
An outside air intake port that is formed in the housing and takes in outside air;
An outside air heat exchanger that is housed in a housing and exchanges heat with 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 that rotates about a rotation center line extending in the vertical direction, and generates a flow through which the outside air flows in the order of the outside air intake port, the outside air heat exchanger, and the outside air discharge port;
An indoor air suction port that is formed in the housing and sucks indoor air through a suction hole in the wall;
An indoor air heat exchanger housed in a housing, thermally connected to an outdoor air heat exchanger and exchanging heat with indoor air;
An indoor air outlet that is formed in the housing and blows out the indoor air after heat exchange with the indoor air heat exchanger into the room through a hole in the wall;
An indoor air fan that generates a flow of indoor air in the order of an indoor air inlet, an indoor air heat exchanger, and an indoor air outlet;
An internal flow passage for suction that connects the suction hole of the wall and the indoor air suction port of the housing, and a connecting portion that has a blowout internal flow channel that connects the blowout hole of the wall and the indoor air discharge port of the housing; Have
An outside air intake port, an outside air discharge port, an indoor air intake port, and an indoor air outlet port are formed on the rear side of the housing and the wall in a direction in which the housing and the wall face each other. It is an integrated air conditioner.

  Furthermore, in the case of the above-described embodiment, the air conditioner 10 (110, 210, 310) 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 (140) 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 (140) and the flow path structure 42, the air conditioning efficiency of the air conditioner 10 (110, 210, 310) is improved.

  In addition, the outside air discharge port 12f (312f) 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 above-described embodiment, the outside air intake port 12e (312e) is formed on the back surface 12a (312a) and the left side surface 12c (312c) of the housing 12 (112, 312). Not limited to. For example, it may be formed on the right side surface of the housing. However, in this case, the outside air outlet is formed on the left side surface. This is to prevent the outside air after heat exchange discharged from the outside air discharge port from flowing into the outside air intake port.

  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.
