[0003] [Patent Document 1] International Publication No. 2023 / 248709 Summary of the Invention [Problem to be solved by the invention]
[0004] When conditioning the air in a space to be conditioned using an integrated air conditioning unit installed outside the space, it is possible that the location where the conditioned air is extracted from the space to be conditioned or the location where the conditioned air is supplied to the space to be conditioned is relatively high relative to the unit. In this case, for example, it is necessary to install duct members connected to the unit to circulate air between the unit and the space to be conditioned. This can lead to problems such as the duct members being bulky and the increased workload of installing the duct members, making the unit difficult to install.
[0005] Therefore, an object of the present disclosure is to make it easier to install an integrated air conditioning device even when the device is installed outside the space to be conditioned and the device conditions the air in the space to be conditioned. [Means for solving the problem]
[0006] In order to solve the above problem, an integrated air conditioning device according to one embodiment of the present disclosure comprises a first heat exchanger that generates conditioned air by exchanging heat between the air to be conditioned and a refrigerant, a second heat exchanger that exchanges heat between the refrigerant that has exchanged heat with the air to be conditioned in the first heat exchanger and outside air, and a housing that integrally houses the first heat exchanger and the second heat exchanger, wherein the housing has a target air inlet that takes in the air to be conditioned inside and a conditioned air outlet that discharges the conditioned air, and the target air inlet and the conditioned air outlet are located at the top of the housing. [Effects of the Invention]
[0007] According to one aspect of the present disclosure, even when an integrated air conditioning device is installed outside the space to be conditioned and the device conditions the air in the space to be conditioned, the device can be easily installed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0009] Hereinafter, an embodiment will be described with reference to the drawings. (Embodiment) FIG. 1 is a front view of an all-in-one air conditioning apparatus (hereinafter also simply referred to as "apparatus") 1 according to an embodiment. FIG. 2 is a functional block diagram showing the configuration of the apparatus 1 of FIG. 1. As shown in FIGS. 1 and 2, the apparatus 1 comprises a housing 2 and long duct members 3 and 4 detachably connected to the housing 2. The apparatus 1 further comprises a first heat exchanger E1, a first fan F1, a second heat exchanger E2, a second fan F2, a compressor CP, a pressure reducer CR, a control unit C, a switching valve V, a refrigerant pipe R, and a drain pipe D. The apparatus 1 is driven (operated) in one of a plurality of drive modes, including a cooling mode and a heating mode. The apparatus 1 of this embodiment is portable so that it can be carried by a person and used at a predetermined location.
[0010] As will be described in detail later, the device 1 has the target air intake port 2a and the conditioned air discharge port 2b arranged at the top of the housing 2. The top here refers, for example, to a position above the center of the vertical dimension of the housing 2. This allows air to circulate efficiently between the device 1 and the conditioning target space 50, even when the device 1 is installed outside the conditioning target space 50 (see FIG. 3) and the device 1 conditions the conditioning target air, which is the air within the conditioning target space 50.
[0011] The housing 2 integrally houses at least the first heat exchanger E1 and the second heat exchanger E2. In this embodiment, the housing 2 integrally houses the heat exchangers E1 and E2, as well as the first fan F1, the second fan F2, the compressor CP, the pressure reducer CR, the control unit C, the switching valve V, and the refrigerant pipe R. As an example, the housing 2 has a rectangular parallelepiped appearance, with the front surface 20b and the back surface 20c being larger than the pair of side surfaces 20d and 20e. This reduces the depth dimension (the dimension perpendicular to the paper surface of FIG. 1) of the housing 2 compared to the width dimension (the dimension horizontally to the paper surface of FIG. 1). Therefore, the device 1 can be easily installed close to the target space 50, facing in the direction perpendicular to the front surface 20b and the back surface 20c (the depth direction).
[0012] The first heat exchanger E1 generates conditioned air by exchanging heat between the air to be conditioned, which is supplied from outside, and a refrigerant. The air to be conditioned can be, for example, air in a space 50 to be conditioned inside a building such as a house, but is not limited to this and may also be air in a space 50 to be conditioned inside a vehicle such as an automobile. The first fan F1 blows air to the first heat exchanger E1. By using the first fan F1, for example, an air flow is formed when the air to be conditioned is taken into the device 1 and the conditioned air is supplied to the space 50 to be conditioned. The first fan F1 has a fan and an electric motor M1 that rotates the fan. The first fan F1 includes, for example, a sirocco fan.
[0013] The second heat exchanger E2 exchanges heat with outside air after the refrigerant has exchanged heat with the air to be conditioned in the first heat exchanger E1. The outside air can be, but is not limited to, outdoor air, and may be air from a space other than the space to be conditioned 50, such as the inside of a building or vehicle. The second fan F2 blows air to the second heat exchanger E2. The second fan F2 has a fan and an electric motor M2 that rotates the fan. The second fan F2 includes, for example, a propeller fan.
[0014] In the device 1 of this embodiment, a first heat exchanger E1 and a second heat exchanger E2 are arranged side by side in the vertical direction inside the housing 2. As an example, the first heat exchanger E1 and the second heat exchanger E2 are arranged in positions where they overlap each other when viewed from the vertical direction. A partition wall 2f is arranged between the first heat exchanger E1 and the second heat exchanger E2 to suppress unnecessary mixing of air. The partition wall 2f extends horizontally inside the housing 2.
[0015] The refrigerant pipe R circulates a refrigerant inside the casing 2. As shown in FIG. 2, the refrigerant pipe R includes a plurality of pipes RP1 to RP5. The pipe RP1 connects the second heat exchanger E2 and the pressure reducer CR. The pipe RP2 connects the pressure reducer CR and the first heat exchanger E1. The pipe RP3 connects the first heat exchanger E1 and the switching valve V. The pipe RP4 connects the switching valve V and the compressor CP. The pipe RP5 connects the compressor CP and the second heat exchanger E2. In the device 1, the refrigerant circulates through the refrigerant pipe R among the heat exchangers E1 and E2, the compressor CP, and the pressure reducer CR.
[0016] The switching valve V switches the flow direction of the refrigerant flowing through the refrigerant pipe R. The switching valve V is, for example, a four-way valve, but is not limited to this. The switching valve V is, for example, a solenoid valve. The device 1 further includes various valve devices, strainers, etc. as appropriate. The control unit C controls various electrical components included in the device 1. As an example, the control unit C controls the electric motors M1 and M2, the compressor CP, the pressure reducer CR, and the switching valve V. The control unit C includes a calculation unit that performs predetermined calculations and a memory unit that stores a control program read by the calculation unit. The calculation unit is realized by a processor such as a CPU, and the memory unit is realized by a memory such as a ROM or RAM. The pressure reducer CR reduces the pressure of the refrigerant flowing through the refrigerant pipe R.
[0017] The pressure reducer CR reduces the pressure of the refrigerant and includes, for example, a pressure reducing valve. The drain pipe D extends from the lower part of the housing 2 to the outside and drains water generated inside the housing 2 to the outside. The bottom surface of the housing 2 is provided with an inclined portion 2e that guides water collected at the bottom of the housing 2 toward the drain pipe D.
[0018] The device 1 also includes at least one electrical component housed in a housing 2, a power line L that supplies externally supplied power to the electrical component, and a power supply unit P that adjusts the power. The power line L includes a wiring L1, a first wiring terminal T1 disposed on one end of the wiring L1 and electrically and detachably connected to the electrical component, and a second wiring terminal T2 disposed on the other end of the wiring L1 and connecting the power line L to an external electrical wiring. The device 1 also includes a housing terminal T3 disposed in the housing 2 below the connection position of the first wiring terminal T1 to the electrical component, electrically connected to the electrical component, and detachably connected to the first wiring terminal T1. The housing terminal T3 is electrically connected to the electrical component via a wiring L2 disposed inside the housing 2. The first wiring terminal T1 is configured so that a user can pull it out from the electrical component side and connect it to the housing terminal T3. This allows the device 1 to receive power via the power line L from either the electrical component side or the housing terminal T3 side.
[0019] The at least one electrical component in this embodiment includes, for example, an electric motor M1 included in the first fan F1, an electric motor M2 included in the second fan F2, and a control unit C. The device 1 also includes, for example, a temperature sensor S connected to the control unit C and configured to detect the temperature of the air to be conditioned that has been taken into the housing 2, and an operation unit 21 that allows the user to turn the air conditioning device 1 on and off, switch between drive modes, and the like. Instead of or in addition to the operation unit 21, the device 1 may include a reception unit that receives user operations via a mobile device such as a smartphone or a remote control.
[0020] Here, the housing 2 has a target air inlet 2a that takes in air to be conditioned inside, and a conditioned air outlet 2b that discharges the conditioned air. The target air inlet 2a and the conditioned air outlet 2b are located at the top of the housing 2. In this embodiment, the target air inlet 2a and the conditioned air outlet 2b are located on the top surface 20a of the housing 2, as an example.
[0021] The housing 2 also has an outside air inlet 2d that takes in outside air into the housing 2, and an outside air outlet 2c that discharges the heat-exchanged outside air to the outside of the housing 2. In this embodiment, the outside air inlet 2d is located on the back surface 20c of the housing 2, and the outside air outlet 2c is located on the front surface 20b of the housing 2. In this manner, in the device 1, the target air inlet 2a and the conditioned air outlet 2b are located on the same surface of the housing 2, whereas the outside air inlet 2d and the outside air outlet 2c are located on different surfaces of the housing 2.
[0022] The device 1 also includes a long duct member that is connected to at least one of the target air intake 2a and the conditioned air outlet 2b and extends to the outside of the housing 2. Specifically, the device 1 of this embodiment includes, as an example, a first duct member 3 connected to the target air intake 2a and a second duct member 4 connected to the conditioned air outlet 2b. The duct members 3 and 4 are flexible tubular members that are configured to be flexible and bendable in the longitudinal direction. The duct members 3 and 4 include, as an example, bellows pipes. One end 3a of the first duct member 3 is detachably connected to the target air intake 2a. One end 4a of the second duct member 4 is detachably connected to the conditioned air outlet 2b. The other ends 3b and 4b of the duct members 3 and 4 are arranged to open toward the conditioned space 50. The other ends 3b, 4b of the duct members 3, 4 are preferably positioned by adjusting the distance between them or the opening directions between them so that the air flowing through the openings 3c, 4c of the duct members 3, 4 does not directly interfere with each other.
[0023] Next, the installation of the device 1 using the duct members 3 and 4 will be described. FIG. 3 is a diagram showing the state of use of the device 1 of FIG. 1. As shown in FIG. 3, a user places the device 1 near the space 50 to be conditioned. At this time, the user installs the device 1 while maintaining a certain distance from the wall 51 separating the space 50 to be conditioned from other spaces so that outside air can easily be taken into the housing 2 through the outside air intake 2d. The user positions the openings 3c and 4c of the other ends 3b and 4b of the duct members 3 and 4 facing the space 50 to be conditioned, and may directly fix the other ends 3b and 4b of the duct members 3 and 4 to the wall 51 or may indirectly fix them to the wall 51 using a jig such as a support structure 52. The support structure 52 supports the other ends 3b and 4b of the duct members 3 and 4 so that no gap is created between the outer peripheries of the other ends 3b and 4b and the space 50 to be conditioned.
[0024] The user also takes out the power line L from the other end 3b of the first duct member 3 through the target air intake 2a and the inside of the first duct member 3, and electrically connects the second wiring terminal T2 to a power supply circuit (in the example of FIG. 3, an outlet installed indoors) located on the side of the harmonizing target space 50. This ensures power supply to the device 1. After completing the above settings, the user uses the device 1.
[0025] Next, the device 1 during operation will be described. In cooling mode, the second fan F2 is driven, causing outside air to be drawn into the housing 2 through the outside air inlet 2d. The refrigerant then exchanges heat with the outside air in the second heat exchanger E2 and is liquefied. The outside air flows through the housing 2 from the outside air inlet 2d toward the outside air outlet 2c. After heat exchange, the outside air is discharged to the outside of the housing 2 through the outside air outlet 2c. Since the outside air outlet 2c faces away from the wall 51 of the housing 2, the outside air discharged from the outside air outlet 2c is prevented from hitting the wall 51. The liquefied refrigerant is then sent to the pressure reducer CR through the pipe RP1. The pressure reducer CR reduces the pressure of the liquefied refrigerant. The liquefied refrigerant is then sent to the first heat exchanger E1 through the pipe RP2.
[0026] Furthermore, when the first fan F1 is driven, the air to be conditioned is taken into the housing 2 from the target air intake port 2a through the first duct member 3. Then, in the first heat exchanger E1, the air to be conditioned exchanges heat with the liquefied refrigerant and is cooled. This generates conditioned air. The conditioned air is discharged from the conditioned air outlet port 2b through the second duct member 4 to the space 50 to be conditioned. As a result of this heat exchange in the first heat exchanger E1, the refrigerant vaporizes. The vaporized refrigerant is sent to the compressor CP through piping RP3, switching valve V, and piping RP4. The compressor CP compresses and discharges the vaporized refrigerant. The vaporized refrigerant returns to the second heat exchanger E2 through the switching valve V and piping RP5.
[0027] Furthermore, in the heating mode, the second blower F2 is driven, causing outside air to be drawn into the interior of the casing 2 through the outside air inlet 2d. Thereafter, in the second heat exchanger E2, the refrigerant exchanges heat with the outside air and is vaporized. The outside air flows through the interior of the casing 2 from the outside air inlet 2d toward the outside air outlet 2c. After heat exchange, the outside air is discharged to the outside of the casing 2 through the outside air outlet 2c. The vaporized refrigerant is sent to the compressor CP through the pipe RP4 and the switching valve V. The compressor CP compresses and discharges the vaporized refrigerant. The vaporized refrigerant is sent to the first heat exchanger E1 through the pipe RP5, the switching valve V, and the pipe RP3.
[0028] Furthermore, when the first fan F1 is driven, the air to be conditioned is taken into the housing 2 from the target air intake port 2a through the first duct member 3. Then, in the first heat exchanger E1, the air to be conditioned exchanges heat with the vaporized refrigerant and is heated. This generates conditioned air. The conditioned air is discharged from the conditioned air outlet 2b through the second duct member 4 to the space 50 to be conditioned. As a result of this heat exchange in the first heat exchanger E1, the refrigerant liquefies. The liquefied refrigerant is sent to the pressure reducer CR through the piping RP2. The refrigerant is decompressed by the pressure reducer CR and becomes a two-phase gas-liquid refrigerant. The two-phase gas-liquid refrigerant returns to the second heat exchanger E2 through the piping RP1. Moisture, such as condensation, generated within the housing 2 while the device 1 is in operation is discharged to the outside of the housing 2 through the drain pipe D. The device 1 can also be operated without using the duct members 3 and 4.
[0029] As explained above, the device 1 comprises a first heat exchanger E1 that generates conditioned air by exchanging heat between air to be conditioned, which is supplied from outside, and a refrigerant, a second heat exchanger E2 that exchanges heat with outside air after the refrigerant has exchanged heat with the air to be conditioned in the first heat exchanger E1, and a housing 2 that integrally houses the first heat exchanger E1 and the second heat exchanger E2. The housing 2 also has a target air inlet 2a that takes in the air to be conditioned inside, and a conditioned air outlet 2b that discharges the conditioned air. The target air inlet 2a and the conditioned air outlet 2b are located at the top of the housing 2.
[0030] According to the device 1 having the above configuration, the target air intake port 2a and the conditioned air exhaust port 2b are disposed at the top of the housing 2. Therefore, when the device 1 is installed outside the space to be conditioned 50 to condition the air in the space to be conditioned 50, even if the position where the conditioned air is taken out of the space to be conditioned 50 or the position where the conditioned air is supplied to the space to be conditioned 50 is relatively high relative to the device 1, the duct members 3 and 4 that circulate air between the device 1 and the space to be conditioned 50 can be easily arranged. This prevents the duct members 3 and 4 from becoming bulky, and reduces the workload of arranging the duct members 3 and 4. As a result, the device 1 can be easily installed. Therefore, even when the device 1 is installed outside the space to be conditioned 50 and conditions the air in the space to be conditioned 50 using the device 1, air can be efficiently circulated between the device 1 and the space to be conditioned 50.
[0031] Furthermore, because the target air intake 2a and the conditioned air discharge 2b are located at the top of the housing 2, even if the extraction position and the supply position are located relatively high relative to the device 1, the target air intake 2a and the conditioned air discharge 2b can be brought close to the extraction position and the supply position. This makes it possible to reduce the length dimensions of the duct members 3 and 4, and therefore to prevent the temperature-adjusted conditioned air from being affected by the heat of outside air via the second duct member 4. Therefore, a stable air conditioning effect can be obtained.
[0032] As another example, the target air intake 2a and the conditioned air discharge 2b are arranged on the top surface 20a of the housing 2. This makes it easier to handle the duct members 3, 4 that circulate air between the device 1 and the conditioned space 50. Therefore, the bulkiness of the duct members 3, 4 is further reduced, and the workload of arranging the duct members 3, 4 can be further reduced.
[0033] Furthermore, in this embodiment, the first heat exchanger E1 and the second heat exchanger E2 are arranged side by side in the vertical direction inside the housing 2. This makes it possible to reduce the horizontal dimension of the housing 2 compared to, for example, a case in which the first heat exchanger E1 and the second heat exchanger E2 are arranged side by side in the horizontal direction. As a result, while reducing the installation space for the device 1, it is possible to easily install the device 1 close to the position where the air to be conditioned is taken out from the space to be conditioned 50 or the position where the conditioned air is supplied to the space to be conditioned 50.
[0034] In addition, the device 1 of this embodiment includes at least one electrical component housed in the housing 2 and a power line L that supplies externally supplied power to the electrical component, and the power line L extends from the inside to the outside of the housing 2 through the target air intake 2a.
[0035] According to the above configuration, the power lines L extend from the inside to the outside of the housing 2 through the target air intake 2a, making it easy to arrange the power lines L upstream in the direction of air flow toward the first heat exchanger E1. Therefore, for example, when the device 1 is operated in cooling mode, it is possible to prevent moisture from condensing on the first heat exchanger E1 and its surroundings from adhering to the power lines L. This allows the device 1 to be operated stably.
[0036] In addition, the device 1 of this embodiment is provided with a long first duct member 3 that is connected to an opening that is at least one of the target air intake port 2a and the conditioned air exhaust port 2b and extends from the housing 2 to the outside, and the power line L passes through the inside of the first duct member 3 and extends to the outside from the side opposite the opening side of the first duct member 3.
[0037] According to the above configuration, the power lines L can be protected by the first duct member 3, so even if the device 1 is installed outdoors, for example, it is possible to prevent electrical malfunctions of the device 1 caused by moisture such as rain and dew adhering to the power lines L. Therefore, the device 1 can be operated stably.
[0038] Furthermore, the power line L of this embodiment has a first wiring terminal T1, which is a wiring terminal that is electrically and detachably connected to an electrical component. This allows the power line L to be easily electrically connected to the electrical component by electrically connecting the electrical component to the first wiring terminal T1. Furthermore, for example, the power line L can be easily replaced with a power line L having a different length or specifications.
[0039] In addition, the device 1 of this embodiment is provided with a housing terminal T3 that is arranged in the housing 2 below the connection position of the first wiring terminal T1 to the electrical component, is electrically connected to the electrical component, and is electrically connected to the first wiring terminal T1 in a manner that allows it to be freely attached and detached.
[0040] According to the above configuration, by electrically connecting the first wiring terminal T1 and the electrical component at the connection position of the first wiring terminal T1 to the electrical component, even if the extraction position of the air to be conditioned from the space to be conditioned 50 or the supply position of the conditioned air to the space to be conditioned 50 is at a relatively high position relative to the device 1, it is possible to easily supply power to the device 1 from the space to be conditioned 50 side via the power line L through the extraction position or the supply position. Furthermore, by electrically connecting the first wiring terminal T1 and the housing terminal T3, it is possible to extend the power line L, for example, below the connection position of the first wiring terminal T1 to the electrical component, and supply power to the device 1 via the power line L. This makes it possible to expand the manner in which power is supplied to the device 1.
[0041] In addition, the device 1 of this embodiment is equipped with a first fan F1 that blows air to the first heat exchanger E1, a second fan F2 that blows air to the second heat exchanger E2, and a control unit C that controls the first fan F1 and the second fan F2, and the control unit C is located upstream of the first heat exchanger E1 in the air flow direction from the target air intake 2a to the conditioned air outlet 2b.
[0042] According to the above configuration, the control unit C is disposed at a position upstream of the first heat exchanger E1 in the direction of air flow from the target air inlet 2a toward the conditioned air outlet 2b, and therefore, when the device 1 is operated in cooling mode, for example, it is possible to prevent moisture from condensation that occurs on and around the first heat exchanger E1 from adhering to the control unit C. Furthermore, the control unit C can be air-cooled by the air to be conditioned that is taken into the housing 2 from the target air inlet 2a. Therefore, the control unit C can be operated stably.
[0043] Furthermore, the control unit C in this embodiment is disposed in a position that does not overlap the lower portions of the first heat exchanger E1 and the second heat exchanger E2. This prevents moisture condensing from the first heat exchanger E1 and the second heat exchanger E2 from contacting the control unit C. This allows the control unit C to be driven more stably.
[0044] Furthermore, the housing 2 of this embodiment has an outside air inlet 2d that takes in outside air and an outside air outlet 2c that discharges the heat-exchanged outside air, with the outside air inlet 2d and the outside air outlet 2c being located on the side of the housing 2. This allows the outside air inlet 2d and the outside air outlet 2c to be positioned without interfering with the target air inlet 2a and the conditioned air outlet 2b. This allows the device 1 to operate stably.
[0045] Furthermore, the device 1 of this embodiment is driven in either a heating mode in which the temperature of the conditioned air is higher than the air to be conditioned, or a cooling mode in which the temperature of the conditioned air is lower than the air to be conditioned. As a result, in either the heating mode or the cooling mode, when the device 1 is installed outside the space to be conditioned 50 and conditions the air in the space to be conditioned 50 using the device 1, air can be circulated efficiently between the device 1 and the space to be conditioned 50.
[0046] Furthermore, in the device 1 of this embodiment, the airflow direction of the first fan F1 coincides with the direction in which the inlet 2a and outlet 2b are aligned in the housing 2 (the width direction of the housing 2), while the airflow direction of the second fan F2 (the depth direction of the housing 2) intersects with this direction. This allows the overall depth dimension of the device 1 to be reduced. Furthermore, since the airflow area of the second fan F2 can be increased, a second fan F2 including a large fan can be used. This allows the heat exchange efficiency of the second heat exchanger E2 to be improved. Below, the modified examples will be described, focusing on the differences from the embodiment.
[0047] (First Modification) Fig. 4 is a side view of an all-in-one air conditioner 101 pertaining to a first modified example. As shown in Fig. 4, in the device 101, the target air intake 2a and the conditioned air outlet 2b are arranged at the top of the housing 102, but are arranged on a side surface or the like (for example, the front surface 120b) of the housing 102. In the device 101, as an example, the target air intake 2a and the conditioned air outlet 2b are arranged side by side at the top of the same side surface. A first duct member 3 is connected to the target air intake 2a, and a second duct member 4 is connected to the conditioned air outlet 2b.
[0048] As in this first modified example, the target air intake 2a and the conditioned air outlet 2b do not necessarily have to be located on the upper surface 120a of the housing 102. The target air intake 2a and the conditioned air outlet 2b may also be located on different surfaces of the housing 2. With this configuration, the device 101 of this modified example also provides the same effects as the device 1.
[0049] (Second Modification) FIG. 5 is a partial view of an all-in-one air conditioning device 201 according to a second modified example. FIG. 6 is a top view of the device 201 of FIG. 5. FIG. 6 shows a state in which the duct members 3 and 4 have been detached from the housing 2, and the first wiring terminal T1 has been detached from the electrical component terminal T4. As shown in FIGS. 5 and 6, the device 201 includes an electrical component terminal T4. The electrical component terminal T4 is housed in the housing 2 and is detachably electrically connected to the first wiring terminal T1 of the power line L, thereby electrically connecting the first wiring terminal T1 to an electrical component (for example, a control unit C). In the example shown in FIGS. 5 and 6, the electrical component terminal T4 is disposed on a connection adapter 22 electrically connected to the electronic component. The connection adapter 22 may be omitted, and the electrical component terminal T4 may be disposed directly on the electronic component. The target air intake 2a is disposed on the top surface 20a of the housing 2, similar to the device 1. 6, the electrical component terminals T4 are exposed to the outside from the target air intake port 2a when viewed from above the housing 2. The target air intake port 2a has an inner diameter large enough for a user's hand to fit inside.
[0050] According to the second modification, the user can easily attach and detach the first wiring terminal T1 of the power line L to and from the electrical component terminal T4 by hand through the target air intake 2a arranged on the top surface 20a of the housing 2.

[0051] The present disclosure is not limited to the above-described embodiments and variations, and the configurations and methods thereof may be changed, added, combined, or deleted without departing from the spirit of the present disclosure. In the above-described embodiments, an example was shown in which the device 1 is installed and used outdoors. When an integrated air conditioning device is used outdoors, for example, the burden of drainage treatment from the drain pipe is reduced, and there are advantages in that the installation space for the device is not required compared to when the device is installed indoors or in a vehicle. However, the present disclosure is not limited to this, and the integrated air conditioning device may also be installed and used indoors or in a vehicle.
[0052] (Addendum) The above description of the embodiment and modifications discloses the following techniques. [Technology 1] a first heat exchanger that generates conditioned air by exchanging heat between the air to be conditioned and a refrigerant; a second heat exchanger that exchanges heat with outside air after the refrigerant has exchanged heat with the air to be conditioned in the first heat exchanger; a housing that integrally houses the first heat exchanger and the second heat exchanger, The housing has a target air intake port that takes in the air to be conditioned inside, and a conditioned air exhaust port that exhausts the conditioned air, An integrated air conditioning device, wherein the target air intake and the conditioned air outlet are arranged at the top of the housing.
[0053] According to the above configuration, when conditioning the air of a space to be conditioned using an integrated air conditioning device installed outside the space to be conditioned, even if the position where the conditioned air is taken out of the space to be conditioned or the position where the conditioned air is supplied to the space to be conditioned is relatively high relative to the device, the target air intake and the conditioned air outlet are located at the top of the housing, making it easy to, for example, route duct members that circulate air between the device and the space to be conditioned. This reduces the bulkiness of the duct members and the workload of arranging the ducts. As a result, the device can be easily installed. Therefore, even when conditioning the air of a space to be conditioned using an integrated air conditioning device installed outside the space to be conditioned, air can be efficiently circulated between the device and the space to be conditioned.
[0054] Furthermore, because the target air intake and conditioned air outlet are located at the top of the housing, even if the extraction position and the supply position are relatively high relative to the device, the target air intake and conditioned air outlet can be moved closer to the extraction position and the supply position. This reduces the length of the duct member, thereby preventing the temperature-adjusted conditioned air from being affected by the heat of outside air through the duct member. This results in a stable air conditioning effect.
[0055] [Technology 2] The integrated air conditioning device according to technology 1, wherein the target air intake and the conditioned air discharge are arranged on the top surface of the housing.
[0056] According to the above configuration, the duct member that circulates air between the device and the target space can be arranged more easily, which further reduces the bulkiness of the duct member and further reduces the workload of arranging the duct.
[0057] [Technology 3] The all-in-one air conditioner according to Technique 1 or 2, wherein the first heat exchanger and the second heat exchanger are arranged side by side in the vertical direction inside the housing.
[0058] With the above configuration, the horizontal dimension of the housing can be reduced compared to when the first heat exchanger and the second heat exchanger are arranged side by side in the horizontal direction. As a result, the arrangement space for the device can be reduced, and the device can be easily arranged close to the position where the air to be conditioned is taken out from the space to be conditioned or the position where the conditioned air is supplied to the space to be conditioned.
[0059] [Technology 4] at least one electrical component housed in the housing; a power line for supplying externally supplied power to the electrical component; The all-in-one air conditioner according to any one of Techniques 1 to 3, wherein the power lines extend from the inside to the outside of the housing through the target air intake.
[0060] According to the above configuration, the power lines extend from the inside to the outside of the housing through the target air intake, making it easy to arrange the power lines upstream of the first heat exchanger in the direction of air flow. Therefore, when the device is operated in cooling mode, for example, condensation that occurs on and around the first heat exchanger can be prevented from adhering to the power lines. Therefore, the device can be operated stably.
[0061] [Technology 5] at least one electrical component housed in the housing; a power line extending from the housing to the outside and supplying power supplied from the outside to the electrical component; a long duct member connected to an opening that is at least one of the target air intake port and the conditioned air discharge port and extending from the housing to the outside, The all-in-one air conditioner according to any one of Techniques 1 to 4, wherein the power lines pass through the inside of the duct member and extend from the opposite side of the duct member to the opening to the outside.
[0062] According to the above configuration, the power lines can be protected by the duct member, so that even when the device is installed outdoors, electrical problems caused by moisture such as rain and dew adhering to the power lines can be prevented, allowing the device to operate stably.
[0063] [Technology 6] The integrated air conditioning device according to technique 4 or 5, wherein the power line has a wiring terminal that is electrically and detachably connected to the electrical component.
[0064] According to the above configuration, by electrically connecting the electrical component to the wiring terminal, the power line can be easily electrically connected to the electrical component. Furthermore, for example, power lines of different lengths or specifications can be easily replaced.
[0065] [Technology 7] The integrated air conditioning device described in Technology 6 is provided with a housing terminal that is arranged in the housing below the connection position of the wiring terminal to the electrical component, is electrically connected to the electrical component, and is electrically connected to the wiring terminal in a manner that allows it to be freely attached and detached.
[0066] According to the above configuration, by electrically connecting the wiring terminal and the electrical component at the connection position, even if the position where the conditioned air is taken out from the space to be conditioned or the position where the conditioned air is supplied to the space to be conditioned is relatively high relative to the device, it is possible to easily supply power to the device from the space to be conditioned via a power line through the take-out position or the supply position. Furthermore, by electrically connecting the wiring terminal and the housing terminal, it is possible to extend a power line below the connection position, for example, and supply power to the device through the power line. This makes it easy to supply power to the device.
[0067] [Technology 8] an electric component terminal housed in the housing and detachably connected electrically to the wiring terminal, electrically connecting the wiring terminal to the electric component; the target air intake is disposed on the top surface of the housing; The all-in-one air conditioner according to claim 6 or 7, wherein the electrical component terminals are exposed to the outside from the target air intake port when viewed from above the housing.
[0068] According to the above configuration, the wiring terminal can be electrically connected to and disconnected from the electrical component terminal through the target air intake port located on the top surface of the housing, thereby improving user convenience when electrically connecting the wiring terminal to the electrical component.
[0069] [Technology 9] a first fan that blows air to the first heat exchanger; a second fan that sends air to the second heat exchanger; a control unit that controls the first fan and the second fan, The integrated air conditioning device described in any one of techniques 1 to 8, wherein the control unit is positioned upstream of the first heat exchanger in the air flow direction from the target air intake port toward the conditioned air outlet.
[0070] According to the above configuration, the control unit is located upstream of the first heat exchanger in the direction of air flow from the target air intake to the conditioned air outlet. Therefore, when the device is operated in cooling mode, for example, moisture from condensation that occurs on the first heat exchanger and its surroundings can be prevented from adhering to the control unit. Furthermore, the control unit can be air-cooled by the air to be conditioned that is drawn into the housing through the target air intake. Therefore, the control unit can be operated stably.
[0071] [Technology 10] the housing has an outside air inlet for taking the outside air inside and an outside air outlet for discharging the outside air that has been heat exchanged, The all-in-one air conditioner according to any one of techniques 1 to 9, wherein the outside air inlet and the outside air outlet are arranged on a side surface of the housing.
[0072] According to the above configuration, the outside air inlet and the outside air outlet can be arranged without interfering with the target air inlet and the conditioned air outlet, thereby enabling the device to be operated stably.
[0073] [Technology 11] a heating mode in which the temperature of the conditioned air is higher than the temperature of the air to be conditioned; a cooling mode in which the temperature of the conditioned air is lower than the temperature of the air to be conditioned.
[0074] According to the above configuration, in either heating mode or cooling mode, when an integrated air conditioning device is installed outside the space to be conditioned and the device conditions the air in the space to be conditioned, air can be efficiently circulated between the device and the space to be conditioned.
[0075] The present disclosure is not limited to the above-described embodiments, and the configuration can be changed, added, or deleted without departing from the spirit of the present disclosure. Furthermore, the power source of the integrated air conditioning device is not limited to one that supplies power to the device from a power circuit (such as an electrical circuit connected to an outlet installed indoors) that is fixedly installed in a building, etc., but may also be, for example, a portable power source (external power source) such as a battery, or a portable generator.
