[0006] Technical problem to be solved by the utility model

[0007] When using an integrated air conditioning unit located outside the conditioned space to regulate the air in that space, it is conceivable that the outlet location of the conditioned air from the conditioned space, or the supply location of the conditioned air to the conditioned space, is at a higher position than the unit. In this case, for example, it is necessary to arrange ductwork components connected to the unit and facilitating the airflow between the unit and the conditioned space. This results in problems such as large ductwork components and increased workload in ductwork configuration. Consequently, the unit becomes difficult to install.

[0008] Furthermore, there is currently no integrated air conditioning device that can be used in a manner that allows switching between one mode and another mode, namely, setting up and using the air conditioning device in a space where the air to be conditioned exists, and setting up and using the air conditioning device outside the space where the air to be conditioned exists, such as in the field.

[0009] Therefore, the first objective of this invention is to enable easy installation of the integrated air conditioning device even when it is placed outside the space to be conditioned and used to regulate the air in that space. Furthermore, the second objective of this invention is to provide an integrated air conditioning device that can be used in two ways: one where the air conditioning device is installed and used within the space to be conditioned, and the other where it is installed and used outside the space to be conditioned, such as in the field.

[0061] (First Embodiment)

[0062] Figure 1 This is a front view of the integrated air conditioning device (hereinafter also simply referred to as "the device") 1 according to the first embodiment. Figure 2 It means Figure 1 The functional block diagram of the structure of device 1. (See diagram below.) Figure 1 and Figure 2 As shown, device 1 includes a housing 2 and elongated pipe components 3 and 4 detachably connected to the housing 2. Additionally, device 1 includes 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. Device 1 is driven (operated) based on any one of several drive modes, including a cooling mode and a heating mode. Device 1 of this embodiment is portable, allowing it to be carried by a person and used in a designated location.

[0063] As will be described in detail later, in device 1, a specific air inlet 2a and a generated air outlet 2b are disposed on the upper part of housing 2. The term "upper part" here refers to a position, for example, above the center of the vertical dimension of housing 2. Thus, even when device 1 is placed in the adjustment target space 50 (see reference 1), the air inlet 2a and the generated air outlet 2b are both positioned within the upper part of housing 2. Figure 3 When the device 1 is used to regulate the air in the air within the air to be regulated in the external state, the air can also be circulated efficiently between the device 1 and the air to be regulated in the air space 50.

[0064] The housing 2 integrally houses at least the first heat exchanger E1 and the second heat exchanger E2. In this embodiment, the housing 2, in addition to integrally housing the heat exchangers E1 and E2, also integrally houses 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. Furthermore, as an example, the housing 2 has a cuboid shape, with its front side 20b and back side 20c larger than a pair of side sides 20d and 20e. Therefore, the depth dimension of the housing 2 (compared to...) Figure 1 The dimension in the direction orthogonal to the paper surface is controlled to be smaller than the width dimension. Figure 1 Within the range of dimensions (left and right of the paper surface). Therefore, the device 1 is easily positioned close to the adjustment space 50 in a direction orthogonal to the front 20b and back 20c (depth direction).

[0065] The first heat exchanger E1 exchanges heat between specific air and refrigerant, which is either the target air or external air. Thus, the first heat exchanger generates a predetermined generated air. For example, the specific air is the target air, and the generated air is the conditioned air. In other words, the first heat exchanger E1 generates conditioned air by exchanging heat between the target air supplied from the outside and the refrigerant. The target air can be, for example, the air in the conditioned space 50 located within a building such as a house, but is not limited to this; it could also be the air in the conditioned space 50 located within a vehicle such as a car. A first fan F1 supplies air to the first heat exchanger E1. By using the first fan F1, an airflow can be formed, for example, to guide the conditioned air into the device 1 and supply the conditioned air to the conditioned space 50. The first fan F1 has a fan and an electric motor M1 that rotates the fan. The first fan F1 may include, for example, a Sirocco fan.

[0066] The second heat exchanger E2 is configured separately from the first heat exchanger E1, allowing the refrigerant that has exchanged heat with specific air in the first heat exchanger E1 to exchange heat with air other than the specific air in the conditioned air and the outside air. As an example, the second heat exchanger E2 allows the refrigerant that has exchanged heat with the conditioned air in the first heat exchanger E1 to exchange heat with outside air. Outside air can be exemplified as outdoor air, but is not limited to this; for example, it could be air from a space other than the conditioned space 50 inside a building or vehicle. A second fan F2 supplies 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 may include, for example, a propeller fan.

[0067] In the apparatus 1 of this embodiment, a first heat exchanger E1 and a second heat exchanger E2 are arranged vertically inside the housing 2. As an example, the first heat exchanger E1 and the second heat exchanger E2 are arranged in a position where they overlap when viewed from above. A partition wall 2f is provided 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.

[0068] The refrigerant pipe R allows the refrigerant to flow inside the casing 2. For example... Figure 2As shown, the refrigerant pipe R includes multiple pipes RP1 to RP5. Pipe RP1 connects the second heat exchanger E2 and the pressure reducer CR. Pipe RP2 connects the pressure reducer CR and the first heat exchanger E1. Pipe RP3 connects the first heat exchanger E1 and the switching valve V. Pipe RP4 connects the switching valve V and the compressor CP. Pipe RP5 connects the compressor CP and the second heat exchanger E2. In device 1, the refrigerant circulates through the refrigerant pipe R between heat exchangers E1 and E2, compressor CP, and pressure reducer CR.

[0069] The switching valve V switches the flow direction of the refrigerant flowing in the refrigerant line R. One example of the switching valve V is a four-way valve, but it is not limited to this. Another example of the switching valve V is a solenoid valve. The device 1 may also appropriately include various valve devices, strainers, etc. The control unit C controls the various electrical components included in the device 1. As an example, the control unit C controls the motors M1 and M2, the compressor CP, the pressure reducer CR, and the switching valve V. The control unit C includes an arithmetic unit that performs prescribed calculations and a storage unit that stores the control program read from the arithmetic unit. The arithmetic unit is implemented by a processor such as a CPU, and the storage unit is implemented by a memory such as ROM or RAM. The pressure reducer CR reduces the pressure of the refrigerant flowing in the refrigerant line R.

[0070] The pressure reducer CR reduces the pressure of the refrigerant, and for example includes a pressure reducing valve. A drain pipe D extends from the lower part of the housing 2 to the outside, discharging water generated inside the housing 2. An inclined section 2e is provided on the bottom surface of the housing 2 to guide the water collected at the bottom of the housing 2 towards the drain pipe D.

[0071] Additionally, device 1 includes: at least one electrical component housed in housing 2, a wire L supplying external electrical power (electricity) to the electrical component, and a power supply unit P for regulating the electrical power. The wire L has: a wiring L1; a first wiring terminal T1 disposed at one end of the wiring L1 and detachably electrically connected to the electrical component; and a second wiring terminal T2 disposed at the other end of the wiring L1, connecting the wire L to external electrical wiring. Furthermore, device 1 includes a housing terminal T3 disposed in housing 2 at a position lower than the connection point between the first wiring terminal T1 and the electrical component, electrically connected to the electrical component, and detachably electrically connected to the first wiring terminal T1. The housing terminal T3 is electrically connected to the electrical component via the wiring L2 disposed inside housing 2. The first wiring terminal T1 is configured such that a user can pull it out from the electrical component side and connect it to the housing terminal T3. Thus, device 1 can receive power from either the electrical component side or the housing terminal T3 side via the wire L.

[0072] As an example, at least one electrical component in this embodiment includes: a motor M1 of the first fan F1, a motor M2 of the second fan F2, and a control unit C. Additionally, as an example, the device 1 also includes: a temperature sensor S connected to the control unit C, used to detect the temperature of the conditioned air introduced into the housing 2; and an input receiving unit 21, which is an operation unit for the user to perform ON / OFF operations on the air conditioning device 1, switch drive modes, etc. The device 1 may also replace the input receiving unit 21 with a receiving unit that accepts user operations via a portable device such as a smartphone or remote control, or it may include a receiving unit that accepts user operations via the portable device in addition to the input receiving unit 21.

[0073] Here, the housing 2 has a specific air inlet 2a for introducing specific air into the interior and a generated air outlet 2b for discharging generated air. The specific air inlet 2a and the generated air outlet 2b are disposed on the upper part of the housing 2. As an example, in this embodiment, the specific air inlet 2a and the generated air outlet 2b are disposed on the upper surface 20a of the housing 2.

[0074] Furthermore, the housing 2 in this embodiment has an air inlet 2d for introducing external air into the interior of the housing 2, and an air outlet 2c for discharging the external air after heat exchange to the exterior of the housing 2. In this embodiment, the air inlet 2d is disposed on the back surface 20c of the housing 2, and the air outlet 2c is disposed on the front surface 20b of the housing 2. Thus, in the device 1, the specific air inlet 2a and the generated air outlet 2b are disposed on the same surface of the housing 2, while the air inlet 2d and the air outlet 2c are disposed on different surfaces of the housing 2.

[0075] Additionally, device 1 includes a long pipe component connected to an opening that serves as at least one of a specific air inlet 2a and a generated air outlet 2b, and extends outward from the housing 2. Specifically, as an example, device 1 of this embodiment includes a first pipe component 3 connected to the specific air inlet 2a and a second pipe component 4 connected to the generated air outlet 2b. Pipe components 3 and 4 are flexible hoses configured to be telescopic and bendable in the length direction. Pipe components 3 and 4, for example, include corrugated pipes. One end 3a of the first pipe component 3 is detachably connected to the specific air inlet 2a. One end 4a of the second pipe component 4 is detachably connected to the generated air outlet 2b. Furthermore, the other ends 3b and 4b of each of the pipe components 3 and 4 are arranged to open toward the adjustment target space 50. The other ends 3b and 4b of each of the pipe components 3 and 4 are preferably arranged to adjust the distance between them or the direction of their openings, so that the air flowing in the respective openings 3c and 4c of the pipe components 3 and 4 does not directly interfere with each other.

[0076] Next, the setup of device 1 using pipe components 3 and 4 will be explained. Figure 3 It means Figure 1 A diagram showing the state of device 1 during use. (See diagram.) Figure 3 As shown, the user positions the device 1 near the adjustment target space 50. The user positions the device 1 at a certain distance from the wall 51 that separates the adjustment target space 50 from other spaces, facilitating the introduction of external air into the housing 2 through the air inlet 2d. The user can either directly fix the other ends 3b and 4b of the pipe components 3 and 4 to the wall 51 while aligning the openings 3c and 4c of the other ends 3b and 4b towards the adjustment target space 50, or indirectly fix the other ends 3b and 4b of the pipe components 3 and 4 to the wall 51 using a clamp such as a support structure 52. The support structure 52 supports the other ends 3b and 4b in a manner that prevents gaps between the outer periphery of the other ends 3b and 4b of the pipe components 3 and 4 and the adjustment target space 50.

[0077] Additionally, the user removes the wire L from the other end 3b of the first pipe component 3 through the specific air inlet 2a and the interior of each part of the first pipe component 3, and connects the second wiring terminal T2 to the power circuit (located on the adjustment object space 50 side) Figure 3 In this example, the electrical connection is made to an indoor socket. This ensures a stable power supply for device 1. After making the above settings, the user uses device 1.

[0078] Next, the device 1 during operation will be described. In cooling mode, by driving the second fan F2, outside air is introduced into the interior of the housing 2 through the air inlet 2d. Then, in the second heat exchanger E2, the refrigerant exchanges heat with the outside air and liquefies. The outside air flows from the air inlet 2d to the air outlet 2c inside the housing 2. The heat-exchanged outside air is discharged from the air outlet 2c to the outside of the housing 2. At this time, since the air outlet 2c faces the side of the housing 2 opposite to the wall 51, it is possible to prevent the outside air discharged from the air outlet 2c from hitting the wall 51. Furthermore, the liquefied refrigerant is transported to the pressure reducer CR through pipe RP1. The pressure reducer CR reduces the pressure of the liquefied refrigerant. The liquefied refrigerant is then transported to the first heat exchanger E1 through pipe RP2.

[0079] Additionally, by driving the first fan F1, conditioned air, as an example of specific air, is introduced into the interior of the housing 2 through the first duct component 3 from the specific air inlet 2a. Then, in the first heat exchanger E1, the conditioned air is cooled by exchanging heat with liquefied refrigerant. This generates conditioned air, as an example of specified generated air. The conditioned air is discharged from the generated air outlet 2b through the second duct component 4 into the conditioned space 50. During the heat exchange in the first heat exchanger E1, the refrigerant vaporizes. The vaporized refrigerant is transported to the compressor CP through pipe RP3, switching valve V, and pipe RP4. The compressor CP compresses and discharges the vaporized refrigerant. The vaporized refrigerant returns to the second heat exchanger E2 through switching valve V and pipe RP5.

[0080] In heating mode, outside air is drawn into the housing 2 through air inlet 2d by driving the second fan F2. Then, in the second heat exchanger E2, the refrigerant vaporizes by exchanging heat with the outside air. The outside air flows from air inlet 2d to air outlet 2c inside the housing 2. The heat-exchanged outside air is then discharged from air outlet 2c to the outside of the housing 2. The vaporized refrigerant is then transported to the compressor CP via pipe RP4 and switching valve V. The compressor CP compresses and discharges the vaporized refrigerant. The vaporized refrigerant is then transported to the first heat exchanger E1 via pipe RP5, switching valve V, and pipe RP3.

[0081] Additionally, by driving the first fan F1, the target air is introduced into the interior of the housing 2 through the first pipe component 3 from the specific air inlet 2a. Then, in the first heat exchanger E1, the target air is heated by heat exchange with the vaporized refrigerant. This generates conditioned air. The conditioned air is discharged from the generated air outlet 2b through the second pipe component 4 into the conditioned space 50. During the heat exchange in the first heat exchanger E1, the refrigerant liquefies. The liquefied refrigerant is transported to the pressure reducer CR through pipe RP2. The refrigerant is depressurized by the pressure reducer CR, becoming a two-phase gas-liquid mixture. The two-phase refrigerant returns to the second heat exchanger E2 through pipe RP1. Condensation and other moisture generated inside the housing 2 during the operation of the device 1 are discharged to the outside of the housing 2 through the drain pipe D. Furthermore, the device 1 can be driven without using pipe components 3 and 4.

[0082] As described above, the device 1 includes: a first heat exchanger E1 for exchanging heat between specific air and a refrigerant; a second heat exchanger E2, separately configured from the first heat exchanger E1, for exchanging heat between the refrigerant that has exchanged heat with the specific air in the first heat exchanger E1 and air that is not specific air in the conditioned air and the external air; and a housing 2 integrally housing the first heat exchanger E1 and the second heat exchanger E2. Furthermore, the housing 2 has: a specific air inlet 2a for introducing specific air into the interior, and a generated air outlet 2b for discharging predetermined generated air. The specific air inlet 2a and the generated air outlet 2b are disposed on the upper part of the housing 2.

[0083] According to the device 1 with the above structure, a specific air inlet 2a and a generated air outlet 2b are disposed on the upper part of the housing 2. Therefore, when the device 1 is placed outside the regulating space 50 and the air in the regulating space 50 is regulated, even if the outlet position for regulated air from the regulating space 50 or the supply position for regulated air to the regulating space 50 is higher than that of the device 1, the arrangement of the pipe components 3 and 4 that allow air to flow between the device 1 and the regulating space 50 can be easily performed. As a result, the increase in the volume of the pipe components 3 and 4 can be suppressed, and the workload of arranging the pipe components 3 and 4 can be reduced. As a result, the device 1 can be easily installed. Therefore, even when the device 1 is placed outside the regulating space 50 and the air in the regulating space 50 is regulated using the device 1, the air can flow efficiently between the device 1 and the regulating space 50.

[0084] Furthermore, because the specific air inlet 2a and the generated air outlet 2b are located on the upper part of the housing 2, even when the outlet and supply positions are at a higher position relative to the device 1, the specific air inlet 2a and the generated air outlet 2b can still be brought close to the outlet and supply positions. This suppresses the length of the pipe components 3 and 4, thus preventing the temperature-controlled air from being affected by external air heat via the second pipe component 4. Therefore, a stable air conditioning effect can be obtained.

[0085] Furthermore, as an example, a specific air inlet 2a and a generated air outlet 2b are disposed on the upper surface 20a of the housing 2. This makes it easier to arrange the pipe components 3 and 4 that allow air to flow between the device 1 and the regulating space 50. Therefore, it is possible to further suppress the increase in the volume of the pipe components 3 and 4, and further reduce the workload of arranging the pipe components 3 and 4.

[0086] Furthermore, in this embodiment, the first heat exchanger E1 and the second heat exchanger E2 are arranged vertically inside the housing 2. This reduces the horizontal dimension of the housing 2 compared to, for example, arranging the first heat exchanger E1 and the second heat exchanger E2 horizontally. Consequently, the space required for the device 1 can be minimized, and the device 1 can be easily positioned close to either the outlet location for supplying conditioned air from the conditioned space 50 or the supply location for supplying conditioned air to the conditioned space 50.

[0087] In addition, the device 1 of this embodiment includes at least one electrical component housed in the housing 2, and a wire L that supplies electrical power from the outside to the electrical component, the wire L extending from the inside of the housing 2 to the outside through a specific air inlet 2a.

[0088] According to the above structure, since the wire L extends from the inside of the housing 2 to the outside through a specific air inlet 2a, it is easy to position the wire L upstream of the first heat exchanger E1 in the airflow direction. Therefore, for example, when the device 1 is driven in cooling mode, it is possible to suppress the adhesion of condensation moisture generated in and around the first heat exchanger E1 to the wire L. Therefore, the device 1 can be driven stably.

[0089] In addition, the device 1 of this embodiment includes a long first pipe component 3, which is connected to an opening that is at least one of a specific air inlet 2a and a generating air outlet 2b, and extends from the housing 2 to the outside. The wire L passes through the interior of the first pipe component 3 and extends to the outside from the side of the first pipe component 3 opposite to the opening side.

[0090] According to the above structure, since the first conduit component 3 can protect the wire L, electrical malfunctions of the device 1 caused by moisture such as rain or dew adhering to the wire L can be prevented even when the device 1 is installed in the field, for example. Therefore, the device 1 can be driven stably.

[0091] Furthermore, the wire L in this embodiment has a first wiring terminal T1, which is a wiring terminal that is detachably connected to an electrical component. Therefore, by electrically connecting the electrical component to the first wiring terminal T1, the wire L can be easily connected to the electrical component. Additionally, for example, it is possible to easily replace wires L of different lengths and specifications.

[0092] In addition, the device 1 of this embodiment includes a housing terminal T3, which is disposed on the housing 2 below the connection position of the first wiring terminal T1 and the electrical component, and is electrically connected to the electrical component and detachably electrically connected to the first wiring terminal T1.

[0093] According to the above structure, by electrically connecting the first wiring terminal T1 to the electrical component at the connection position between the first wiring terminal T1 and the electrical component, even if the outlet position for supplying regulated air from the regulated space 50 or the supply position for supplying regulated air to the regulated space 50 is at a higher position than the device 1, power can be easily supplied to the device 1 from the regulated space 50 side via the outlet position or the supply position via the wire L. Furthermore, by electrically connecting the first wiring terminal T1 to the housing terminal T3, for example, power can be supplied to the device 1 via the wire L to a position lower than the connection position between the first wiring terminal T1 and the electrical component. Therefore, the methods for supplying power to the device 1 can be expanded.

[0094] In addition, the apparatus 1 of this embodiment includes: a first fan F1 that supplies air to the first heat exchanger E1, a second fan F2 that supplies air to the second heat exchanger E2, and a control unit C that controls the first fan F1 and the second fan F2. The control unit C is arranged upstream of the first heat exchanger E1 in the direction of air flow from a specific air inlet 2a to a generated air outlet 2b.

[0095] According to the above structure, since the control unit C is positioned upstream of the first heat exchanger E1 in the direction of air flow from the specific air inlet 2a to the generating air outlet 2b, for example, when the device 1 is driven in cooling mode, it is possible to suppress the adhesion of condensation moisture generated in and around the first heat exchanger E1 to the control unit C. Furthermore, the control unit C can be air-cooled by introducing specific air from the housing 2a into it. Therefore, the control unit C can be driven stably.

[0096] Furthermore, in this embodiment, the control unit C is positioned so as not to overlap with the respective heat exchangers of the first heat exchanger E1 and the second heat exchanger E2 below. This prevents condensation from the first heat exchanger E1 and the second heat exchanger E2 from contacting the control unit C. Therefore, the control unit C can be driven more stably.

[0097] Furthermore, the housing 2 of this embodiment has an air inlet 2d for introducing external air into the interior and an air outlet 2c for discharging the external air that has undergone heat exchange. The air inlet 2d and the air outlet 2c are disposed on the side of the housing 2. Therefore, the air inlet 2d and the air outlet 2c can be configured to prevent interference with a specific air inlet 2a and to generate an air outlet 2b. Thus, the device 1 can be driven stably.

[0098] Furthermore, as an example, in this embodiment, the specific air is the target air, and the generated air is the conditioned air generated by heat exchange between the target air and the refrigerant. In this case, the device 1 is driven in either a heating mode where the temperature of the conditioned air is higher than that of the target air, or a cooling mode where the temperature of the conditioned air is lower than that of the target air. Thus, in either the heating or cooling mode, when the device 1 is placed outside the target space 50 and the air in the target space 50 is conditioned using the device 1, efficient airflow between the device 1 and the target space 50 can be achieved.

[0099] Furthermore, in this embodiment, the device 1 is configured such that the air delivery direction of the first fan F1 is consistent with the arrangement direction (width direction of the housing 2) of the inlet 2a and outlet 2b of the housing 2, while the air delivery direction (depth direction of the housing 2) of the second fan F2 intersects this arrangement direction. This reduces the overall depth dimension of the device 1. Additionally, since the air delivery area of ​​the second fan F2 can be increased, a second fan F2, including a large fan, can be utilized. This improves the heat exchange efficiency of the second heat exchanger E2. Hereinafter, variations of the first embodiment will be described, focusing on the differences from the first embodiment.

[0100] (First variation)

[0101] Figure 4 This is a side view of the integrated air conditioning unit 101 of the first modified example. Figure 4 As shown, the device 101 is configured such that a specific air inlet 2a and a generated air outlet 2b are disposed on the upper part of the housing 102, and on the side of the housing 102 (for example, the front 120b). In the device 101, as an example, the specific air inlet 2a and the generated air outlet 2b are arranged on the upper part of the same side. A first pipe component 3 is connected to the specific air inlet 2a, and a second pipe component 4 is connected to the generated air outlet 2b.

[0102] As described in this first modification, the specific air inlet 2a and the generated air outlet 2b do not necessarily need to be located on the upper surface 120a of the housing 102. Furthermore, the specific air inlet 2a and the generated air outlet 2b can also be located on different surfaces of the housing 2. The device 101 of this modification, having such a structure, achieves the same effect as device 1.

[0103] (Second variation)

[0104] Figure 5 This is a partial view of the integrated air conditioning unit 201 of the second modification. Figure 6 yes Figure 5A top view of device 201. Figure 6 The text indicates a situation where pipe components 3 and 4 have been removed from housing 2, and the first wiring terminal T1 has been disconnected from electrical component terminal T4. For example... Figure 5 and Figure 6 As shown, device 201 has an electrical component terminal T4. The electrical component terminal T4 is housed in housing 2 and is detachably electrically connected to the first wiring terminal T1 of wire L, thereby electrically connecting the first wiring terminal T1 to an electrical component (for example, control unit C). Figure 5 and Figure 6 In the example shown, the electrical component terminal T4 is disposed on the connection adapter (adapter) 22, which is electrically connected to the electronic component. Alternatively, the connection adapter 22 can be omitted, and the electrical component terminal T4 can be disposed directly on the electronic component. A specific air inlet 2a is disposed on the upper surface 20a of the housing 2, similar to that of device 1. Figure 6 As shown, when viewed from above the housing 2, the electrical component terminal T4 is exposed from the exterior through a specific air inlet 2a. The specific air inlet 2a has an inner diameter that allows a user's hand to enter the interior.

[0105] According to this second modification, through a specific air inlet 2a disposed on the upper surface 20a of the housing 2, the user can easily connect and disconnect the first wiring terminal T1 of the wire L to the electrical component terminal T4 by hand. Therefore, the convenience for the user when electrically connecting the first wiring terminal T1 of the wire L to the electrical component is improved. Hereinafter, the second embodiment of the present invention will be described focusing on the differences from the first embodiment.

[0106] (Second Implementation)

[0107] Figure 7 This is a front view of the device 301 according to the second embodiment. Figure 2 and Figure 7 As shown, device 301, like device 1, includes a housing 2 and long-length pipe components 3 and 4 detachably connected to the housing 2. Additionally, device 301 includes 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. Device 301 is driven (operated) based on either a cooling mode or a heating mode. Furthermore, as an example, device 301 is driven based on any one of the following air supply modes: a "high air supply" mode with a large air volume, a "medium air supply" mode with a moderate air volume, and a "low air supply" mode with a small air volume. Device 301 of this embodiment is portable, allowing it to be carried by a person and used in a designated location.

[0108] In addition, as detailed below, the device 301 can switch between a first setting mode and a second setting mode, wherein the first setting mode is a mode in which the specific air inlet 2a and the generated air outlet 2b lead into the regulating object space 50, and the second setting mode is a mode in which the specific air inlet 2a and the generated air outlet 2b lead out of the regulating object space 50.

[0109] Specifically, the control unit C of the device 301 performs fan control on the first fan F1 and the second fan F2 respectively according to the setting mode of the device 301, and switches the drive mode between the first drive mode and the second drive mode specified regarding the setting mode of the device 301 based on the input information received by the input receiving unit 21.

[0110] Therefore, in the first drive mode and the second drive mode, the air supplied to the first heat exchanger E1 and the second heat exchanger E2 switches between the regulated air and the outside air. Thus, device 301 in the first setting mode (refer to...) Figure 3 ) and second setting mode (refer to Figure 8 In any of the modes, the drive mode can be switched. The first setting mode is to set the device 301 outside the adjustment object space 50, such as in the field, and the second setting mode is to set the device 301 inside the adjustment object space 50 filled with the air of the adjustment object.

[0111] The internal structure of the housing 2 of device 301 is basically the same as that of the housing 2 of device 1. The first heat exchanger E1 exchanges heat between a specific air, either the conditioned air supplied from the outside or the outside air supplied from the outside, and the refrigerant. The conditioned air can be exemplified by the air in the conditioned space 50 located in a building such as a house, but is not limited thereto; for example, it can also be the air in the conditioned space 50 located in a vehicle such as a car. In addition, the outside air can be exemplified by outdoor air, but is not limited thereto; for example, it can also be the air in a space other than the conditioned space 50 inside a building or vehicle.

[0112] In this embodiment, the second heat exchanger E2 is configured separately from the first heat exchanger E1, allowing specific air—different from the air supplied to the first heat exchanger E1—to exchange heat with the refrigerant in the target air and external air. A second fan F2 supplies air to the second heat exchanger E2. In this embodiment, as an example, the first heat exchanger E1 is positioned above the second heat exchanger E2.

[0113] The control unit C controls the various electrical components included in the device 301, including the first fan F1 and the second fan F2. For example, the control unit C controls motors M1 and M2, compressor CP, pressure reducer CR, and switching valve V. The control unit C includes an arithmetic unit and a storage unit. The arithmetic unit performs calculations based on a prescribed control program. This control program includes a program for the control unit C to execute the fan control described later. The storage unit contains the aforementioned control program and is read from the arithmetic unit. The arithmetic unit is implemented by at least one processor, such as a CPU. The storage unit is implemented by at least one memory, such as ROM or RAM. The pressure reducer CR reduces the pressure of the refrigerant flowing in the refrigerant pipe R.

[0114] Additionally, device 301 includes at least one electrical component housed in housing 2, a wire L supplying external power to the electrical component, and a power supply unit P for regulating the power. As an example, the at least one electrical component in this embodiment includes a motor M1 of the first fan F1, a motor M2 of the second fan F2, and a control unit C. Furthermore, as an example, device 301 also includes a temperature sensor S connected to the control unit C to detect the temperature of a specific air introduced into housing 2; and an input receiving unit 21 that receives user input such as turning device 301 on / off or switching drive modes. The input receiving unit 21 may, for example, have an input button for user operation. Alternatively, device 301 may include a communication receiving unit that accepts user operation via a portable device such as a smartphone or remote control, or it may include the communication receiving unit in addition to the input receiving unit 21.

[0115] Here, the housing 2 has a specific air inlet 2a and a generated air outlet 2b. The specific air inlet 2a introduces specific air, which is either the target air or external air, into the interior. The generated air outlet 2b discharges generated air, which is produced by exchanging heat between the specific air and the refrigerant in the first heat exchanger E1. When the device 301 is located outside the target space 50, the specific air is the target air, and the generated air is the target air. Alternatively, when the device 301 is located inside the target space 50, the specific air is external air. The specific air inlet 2a and the generated air outlet 2b are disposed on the upper part of the housing 2. As an example, in this embodiment, the specific air inlet 2a and the generated air outlet 2b are disposed on the upper surface 20a of the housing 2.

[0116] Additionally, the housing 2 has an air inlet 2d and an air outlet 2c separately configured with a specific air inlet 2a and a generated air outlet 2b. For example, when the device 301 is located outside the adjustment target space 50, the air inlet 2d introduces external air into the interior of the housing 2, and the air outlet 2c discharges the heat-exchanged external air to the exterior of the housing 2. Conversely, when the device 301 is located within the adjustment target space 50, the air inlet 2d introduces the regulated air into the interior of the housing 2, and the air outlet 2c discharges the regulated air to the exterior of the housing 2. In this embodiment, the air inlet 2d is located on the back surface 20c of the housing 2, and the air outlet 2c is located on the front surface 20b of the housing 2. Thus, in the device 301, the specific air inlet 2a and the generated air outlet 2b are located on the same surface of the housing 2, while the air inlet 2d and the air outlet 2c are located on different surfaces of the housing 2.

[0117] Additionally, the device 301 has an elongated pipe component that connects to an opening serving as at least one of a specific air inlet 2a and a generated air outlet 2b, and extends to the outside of the housing 2. Specifically, as an example, the device 301 of this embodiment includes a first pipe component 3 connected to the specific air inlet 2a and a second pipe component 4 connected to the generated air outlet 2b. The pipe components 3 and 4 are flexible pipe components, configured to be able to extend and bend in the length direction. For example, the pipe components 3 and 4 include corrugated pipes.

[0118] One end 3a of the first duct component 3 is detachably connected to a specific air inlet 2a. One end 4a of the second duct component 4 is detachably connected to a generated air outlet 2b. Furthermore, the other ends 3b and 4b of each of the duct components 3 and 4 are configured to open towards either the outside or inside of the adjustment target space 50. Preferably, the other ends 3b and 4b of the duct components 3 and 4 are configured to allow adjustment of their distance from each other or their respective airflow direction, so that the air flowing in the openings 3c and 4c of the duct components 3 and 4 does not directly interfere with each other.

[0119] Next, a first configuration mode will be described where the specific air inlet 2a and the generated air outlet 2b lead into the regulated space 50. In this case, the device 301 is located outside the regulated space 50. Specifically, as... Figure 3 As shown, when the device 301 is placed outside the adjustment target space 50 (in this case, outdoors), the user places the device 301 near the adjustment target space 50. In this case, the device 301 is positioned such that it is spaced a certain distance from the wall 51 so that the user can easily introduce outside air into the housing 2 through the air inlet 2d, wherein the wall 51 separates the adjustment target space 50 from other spaces.

[0120] Additionally, the user positions the openings 3c and 4c of the other ends 3b and 4b of the pipe components 3 and 4 towards the adjustment target space 50. The user can directly fix the other ends 3b and 4b of the pipe components 3 and 4 to the wall 51, or indirectly fix them to the wall 51 using a specified clamp such as a support structure 52 mounted on the wall 51. As an example, the support structure 52 includes a plate-like member that supports the other ends 3b and 4b in such a way that no gap is created between the outer peripheral edge of the other ends 3b and 4b of the pipe components 3 and 4 and the adjustment target space 50. Furthermore, the user connects the terminals of the wire L to, for example, a power circuit located on the adjustment target space 50 side. Figure 3 In the example, the electrical connection is made to an indoor socket. This ensures a stable power supply for device 301. Furthermore, by placing device 301 outdoors, heat dissipation during device 301 operation can be easily achieved, and the burden of drainage from drain pipe D can be reduced. Additionally, sufficient installation space for device 301 can be easily secured.

[0121] Next, a second configuration mode will be described where the specific air inlet 2a and the generated air outlet 2b lead out of the regulated space 50. In this configuration, the device 301 is located within the regulated space 50. Figure 8 It means Figure 1 The diagram shows the setting method of device 301 (the setting method within the adjustment object space 50). Specifically, as shown... Figure 8 As shown, when the device 301 is installed within the adjustment space 50, it is positioned at a certain distance from the wall 51 to facilitate the user's easy introduction of the adjustment air into the housing 2 from the air inlet 2d. Furthermore, the user can adjust the drainage position of the drain pipe D to discharge moisture from the drain pipe D to a designated drainage location outside the adjustment space 50.

[0122] Additionally, the user positions the openings 3c and 4c of the other ends 3b and 4b of the pipe components 3 and 4 towards the outside of the adjustment space 50 (here, as an example, the field). Figure 3 Similarly, the user can directly fix the other ends 3b and 4b of the pipe components 3 and 4 to the wall 51, or indirectly fix the other ends 3b and 4b of the pipe components 3 and 4 to the wall 51 using a specified clamp such as the support structure 52 installed on the wall 51. Additionally, the user connects the terminals of the wire L to, for example, a power circuit located on the side of the adjustment target space 50 (in... Figure 4 In the example, the electrical connection is for an indoor socket.

[0123] After making the above settings, the user sets the drive mode of device 301 to either the first drive mode or the second drive mode according to the device 301's configuration. Here, the first drive mode involves the first fan F1 supplying conditioned air to the first heat exchanger E1, where the conditioned air exchanges heat with the refrigerant to generate conditioned air, and the second fan F2 supplying outside air to the second heat exchanger E2, where the refrigerant that has exchanged heat with the conditioned air in the first heat exchanger E1 exchanges heat with the outside air. This first drive mode corresponds to the method of installing device 301 outside the conditioned space 50, such as in the field. Figure 3 (The setting method) is the first setting mode.

[0124] In the second driving mode, the second fan F2 supplies conditioned air to the second heat exchanger E2, where the conditioned air exchanges heat with the refrigerant to generate conditioned air. Meanwhile, the first fan F1 supplies outside air to the first heat exchanger E1, where the refrigerant that has exchanged heat with the conditioned air via the second heat exchanger E2 exchanges heat with the outside air. This second driving mode corresponds to the arrangement of the device 301 within the conditioned space 50. Figure 8 (The setting method) is the second setting mode.

[0125] The drive mode of the device 301 is set, for example, according to a mode setting instruction from the user input to the input receiving unit 21. Alternatively, the user can drive the device 301 by setting its air conditioning mode to either cooling or heating mode.

[0126] Here, as the user sets the drive mode of device 301 to either the first drive mode or the second drive mode, the control unit C executes the prescribed fan control. The fan control will be described below. Figure 9 yes Figure 7 This is a flowchart of the fan control during the initial drive phase of device 301. The initial drive phase refers to, for example, the period from the start of drive of device 301 until the control unit C first determines whether the drive mode of device 301 is the first mode. In the following explanation, "S" indicates a step, and "yes" or "no" after ":" indicates the judgment result of the step described before ":".

[0127] like Figure 9As shown, in the initial stage of driving the device 301, the control unit C determines whether it has received input information that sets the driving mode of the device 301 to either the first driving mode or the second driving mode (S1). The input information is, for example, information input to the device 301 through the input receiving unit 21, but the method of receiving the input information is not limited to this.

[0128] The control unit C continues processing S1 until it determines that input information has been received in S1. In S1, if the control unit C determines that input information has been received (S1: Yes), it then determines whether the drive mode of the setting instruction in the received input information is the first drive mode (S2). In S2, if the control unit C determines that the drive mode of the setting instruction is the first drive mode (S2: Yes), the control unit C then executes fan control for fans F1 and F2 respectively based on the first drive mode (S3).

[0129] In the fan control (S3) of the first drive mode, for example, the control unit C controls the fan so that the rotational speeds of the first fan F1 and the second fan F2 are different from each other. Specifically, in the fan control (S3) of the first drive mode, the control unit C controls motors M1 and M2 so that the rotational speed of the first fan F1 is greater than the rotational speed of the second fan F2. Alternatively, in the fan control (S3) of the first drive mode, the control unit C may switch between the first fan F1 and the second fan F2 as the controlled fan (the control unit C may also switch between the first fan F1 and the second fan F2 so that one of them is the controlled fan). In this case, the control unit C may control the first fan F1 and stop controlling the second fan F2. After completing the execution of the fan control (S3) of the first drive mode, the control unit C ends the process.

[0130] On the other hand, in S2, if the control unit C determines that the drive mode indicated by the setting is not the first drive mode (S2: No), the control unit C then performs fan control on the second drive mode to control the fans F1 and F2 respectively (S4).

[0131] In the fan control (S4) of the second drive mode, for example, the control unit C also controls the fan so that the speeds of the first fan F1 and the second fan F2 are different. Specifically, in the fan control (S4) of the second drive mode, the control unit C controls the motors M1 and M2 so that the speed of the second fan F2 is greater than the speed of the first fan F1. Alternatively, in the fan control (S4) of the second drive mode, the control unit C can switch between the first fan F1 and the second fan F2 as the controlled fan. In this case, the control unit C can also control the second fan F2 and stop the control of the first fan F1. After completing the execution of the fan control (S4) of the second drive mode, the control unit C ends the process. Through the control of the control unit C, even if the device 301 is set up differently, the appropriately temperature-controlled air can be stably supplied to the regulated space 50.

[0132] Next, the air supply control executed by the control unit C during normal operation, after the initial operation of device 301 (after the execution of fan control (S3, S4)), will be explained. After executing fan control (S3, S4), the control unit C executes air supply control to control the first fan F1 and the second fan F2 respectively, based on the new input information (such as air volume adjustment indication information) received by the input receiving unit 21. Figure 10 yes Figure 1 A flowchart of the air supply control during normal operation of device 301.

[0133] like Figure 10 As shown, during normal operation, the control unit C determines whether it has received input information regarding an airflow adjustment instruction via the input receiving unit 21, etc. (S11). In S11, the control unit C continues to perform this determination until it receives input information regarding an airflow adjustment instruction. In S11, if the control unit C determines that it has received input information regarding an airflow adjustment instruction (S11: Yes), it then determines whether the current drive mode of the device 301 is the first drive mode (S12). In S12, if the control unit C determines that the current drive mode of the device 301 is the first drive mode (S12: Yes), the control unit C then performs air supply control to control the airflow of fans F1 and F2 respectively according to the first drive mode (S13).

[0134] In the air supply control (S13) of the first drive mode, for example, the control unit C controls the speeds of the first fan F1 and the second fan F2 to be different. Specifically, in the air supply control (S13) of the first drive mode, the control unit C controls motors M1 and M2, for example, so that the speed of the first fan F1 is greater than the speed of the second fan F2. Alternatively, in the air supply control (S13) of the first drive mode, the control unit C may switch between the first fan F1 and the second fan F2 as the controlled fan. In this case, in the air supply control (S13) of the first drive mode, the control unit C may control the first fan F1 and stop the control of the second fan F2. After completing the air supply control (S13), the control unit C ends the process.

[0135] On the other hand, in S12, if the control unit C determines that the current drive mode of device 301 is not the first drive mode (S12: No), the control unit C then executes air supply control (S14) to control the fans F1 and F2 respectively according to the second drive mode. In this air supply control (S14) under the second drive mode, for example, the control unit C also controls the fan so that the speeds of the first fan F1 and the second fan F2 are different. Specifically, in the air supply control (S14) under the heating mode, the control unit C controls, for example, motors M1 and M2 so that the speed of the second fan F2 is greater than the speed of the first fan F1. Alternatively, in the air supply control (S14) under the heating mode, the control unit C may switch between the first fan F1 and the second fan F2 as the controlled fan. In this case, in the air supply control (S14) under the second drive mode, the control unit C may control the second fan F2 and stop the control of the first fan F1. After completing the execution of air supply control (S14), the control unit C ends the process.

[0136] Through the control of the control unit C, in the device 301 that is driven in either the first drive mode or the second drive mode, the appropriately temperature-controlled air can be stably supplied to the regulated space 50 according to the user's requirements.

[0137] For example, when the drive mode is the first drive mode and the air conditioning mode is the cooling mode, when the user issues an airflow adjustment instruction to the device 301 by operating, for example, the input button of the input receiver 21 or a portable device such as a smartphone or remote control, the control unit C performs fan control (S3) to control the speed of the first fan F1. At this time, if it is necessary to increase the airflow of the first fan F1, the control unit C increases the speed of the first fan F1. On the other hand, when the control unit C performs fan control (S3) on the second fan F2 that generates airflow of external air in the housing 2, it can independently control the speed of the second fan F2 according to the state of the refrigerant, the temperature of the external air, etc., to make it an appropriate speed, regardless of the user's airflow adjustment instruction.

[0138] Furthermore, for example, when the drive mode is the second drive mode and the air conditioning mode is the cooling mode, when the user uses a portable device such as a remote control to instruct the device 301 to adjust the airflow, the control unit C performs fan control (S4) to control the speed of the second fan F2 based on this. At this time, if it is necessary to increase the airflow of the second fan F2, the control unit C increases the speed of the second fan F2. On the other hand, when the control unit C performs fan control (S4) on the first fan F1 that generates airflow of external air in the housing 2, it can control the speed of the first fan F1 to be an appropriate speed independently of the user's airflow adjustment instruction, based on the state of the refrigerant, the temperature of the external air, etc. In this way, in the device 301, the fans of the first fan F1 and the second fan F2, which are controlled by the control unit C to deliver conditioned air to the conditioned space 50, switch between the first drive mode and the second drive mode.

[0139] In addition, the control unit C can also determine in S2 whether the drive mode of the device 301 is the second drive mode and reflect the determination result in the fan control (S3, S4), and determine in S12 whether the drive mode of the device 301 is the second drive mode and reflect the determination result in the air supply control (S13, S14).

[0140] Next, the internal workings of the drive unit 301 will be described. When the drive mode is the first drive mode and the air conditioning mode is cooling mode, external air is introduced into the housing 2 through the air inlet 2d by driving the second fan F2. Then, in the second heat exchanger E2, the refrigerant exchanges heat with the external air and liquefies. The external air flows from the air inlet 2d to the air outlet 2c inside the housing 2. The heat-exchanged external air is then discharged from the air outlet 2c to the outside of the housing 2. Since the air outlet 2c faces the side of the housing 2 opposite to the wall 51, it is possible to prevent the external gas discharged from the air outlet 2c from hitting the wall 51.

[0141] The liquefied refrigerant is delivered to the pressure reducer CR via pipe RP1. The pressure reducer CR reduces the pressure of the liquefied refrigerant. The liquefied refrigerant is then delivered to the first heat exchanger E1 via pipe RP2.

[0142] Additionally, by driving the first fan F1, the target air is introduced into the interior of the housing 2 through the first duct component 3 from a specific air inlet 2a. Then, in the first heat exchanger E1, the target air is cooled by exchanging heat with liquefied refrigerant. This generates conditioned air. The conditioned air is discharged from the generated air outlet 2b through the second duct component 4 into the conditioned space 50. During the heat exchange in the first heat exchanger E1, the refrigerant vaporizes.

[0143] The vaporized refrigerant is delivered to the compressor CP via pipe RP3, switching valve V, and pipe RP4. The compressor CP compresses the vaporized refrigerant and discharges it. The compressed refrigerant returns to the second heat exchanger E2 via switching valve V and pipe RP5.

[0144] Additionally, when the drive mode is the first drive mode and the air conditioning mode is the heating mode, external air is introduced into the interior of the housing 2 through the air inlet 2d by driving the second fan F2. Then, in the second heat exchanger E2, the refrigerant vaporizes by exchanging heat with the external air. The external air flows from the air inlet 2d to the air outlet 2c inside the housing 2. The heat-exchanged external air is discharged from the air outlet 2c to the outside of the housing 2. The vaporized refrigerant is transported to the compressor CP through pipe RP4 and switching valve V. The compressor CP compresses the vaporized refrigerant and discharges it. The compressed refrigerant is transported to the first heat exchanger E1 through pipe RP5, switching valve V, and pipe RP3.

[0145] Additionally, by driving the first fan F1, the target air is introduced into the interior of the housing 2 through the first duct component 3 from a specific air inlet 2a. Then, in the first heat exchanger E1, the target air is heated by exchanging heat with the vaporized refrigerant. This generates conditioned air. The conditioned air is discharged from the generated air outlet 2b through the second duct component 4 into the conditioned space 50. During the heat exchange in the first heat exchanger E1, the refrigerant liquefies.

[0146] The liquefied refrigerant is transported to the pressure reducer CR through pipe RP2. The refrigerant is depressurized by the pressure reducer CR, becoming a two-phase gas-liquid mixture. The two-phase refrigerant returns to the second heat exchanger E2 through pipe RP1. During the operation of the device 301, condensation and other moisture generated inside the casing 2 are discharged to the outside of the casing 2 through drain pipe D.

[0147] When the drive mode is the second drive mode and the air conditioning mode is cooling mode, by driving the first fan F1, outside air is introduced into the interior of the housing 2 through the first duct component 3 from the specific air inlet 2a. Then, in the first heat exchanger E1, the outside air exchanges heat with the vaporized refrigerant. The heat-exchanged outside air is discharged from the generated air outlet 2b through the second duct component 4 to the outside of the regulated space 50. During the heat exchange in the first heat exchanger E1, the refrigerant liquefies.

[0148] The liquefied refrigerant is conveyed to the pressure reducer CR via piping RP2. The pressure reducer CR reduces the pressure of the liquefied refrigerant. The reduced-pressure and liquefied refrigerant is then conveyed to the second heat exchanger E2 via piping RP1.

[0149] Additionally, by driving the second fan F2, the conditioned air is introduced into the interior of the housing 2 through the air inlet 2d. Then, in the second heat exchanger E2, the conditioned air is cooled by exchanging heat with the liquefied refrigerant. This generates conditioned air. The conditioned air is discharged from the air outlet 2c into the conditioned space 50. During the heat exchange in the second heat exchanger E2, the refrigerant vaporizes.

[0150] The vaporized refrigerant is delivered to the compressor CP via pipe RP5 and switching valve V. The compressor CP compresses the vaporized refrigerant and discharges it. The compressed refrigerant returns to the first heat exchanger E1 via switching valve V and pipe RP4.

[0151] Furthermore, when the drive mode is the second drive mode and the air conditioning mode is the heating mode, by driving the first fan F1, outside air is introduced into the interior of the housing 2 through the first duct component 3 from the specific air inlet 2a. Then, in the first heat exchanger E1, the refrigerant exchanges heat with the outside air and vaporizes. The heat-exchanged outside air is then discharged from the generated air outlet 2b through the second duct component 4 to the outside of the regulated space 50.

[0152] The vaporized refrigerant is delivered to the compressor CP via pipe RP3, switching valve V, and pipe RP4. The compressor CP compresses the vaporized refrigerant and discharges it. The compressed refrigerant is then delivered to the second heat exchanger E2 via pipe RP5 and switching valve V.

[0153] Additionally, by driving the second fan F2, the conditioned air is introduced into the interior of the housing 2 through the air inlet 2d. Then, in the second heat exchanger E2, the conditioned air is heated by exchanging heat with the vaporized refrigerant. This generates conditioned air. The conditioned air is discharged from the air outlet 2c into the conditioned space 50. During the heat exchange in the second heat exchanger E2, the refrigerant liquefies.

[0154] The liquefied refrigerant is transported to the pressure reducer CR through pipe RP1. The refrigerant is depressurized by the pressure reducer CR, becoming a two-phase gas-liquid mixture. The two-phase refrigerant returns to the first heat exchanger E1 through pipe RP2. During the operation of the device 301, condensation and other moisture generated inside the casing 2 are discharged to the outside of the casing 2 through drain pipe D.

[0155] As described above, in device 301, the first heat exchanger E1, the second heat exchanger E2, the first fan F1, the second fan F2, and the control unit C are integrally housed in a housing. Furthermore, device 301 is configured to switch between a first setting mode and a second setting mode. The first setting mode is a mode where the specific air inlet 2a and the generated air outlet 2b open into the conditioned space 50, and the second setting mode is a mode where the specific air inlet 2a and the generated air outlet 2b open outside the conditioned space 50. Therefore, an integrated air conditioning device 301 can be provided that can switch between using the first setting mode and the second setting mode. The first setting mode is used when the device 301 is installed and used outside the conditioned space, such as in the field, while the second setting mode is used when the device 301 is installed and used inside the conditioned space 50 where the conditioned air is present.

[0156] Specifically, the control unit C of device 301 performs fan control based on the input information received by the input receiving unit 21, controlling the first fan F1 and the second fan F2 respectively to switch the drive mode between the first drive mode and the second drive mode. Thus, the drive mode of device 301 can be switched between the first drive mode and the second drive mode, and the heat exchanger that performs heat exchange between the regulated air and the outside air can be switched between the first heat exchanger E1 and the second heat exchanger E2.

[0157] Therefore, heat exchangers E1 and E2 can be distributed according to whether the device 301 is installed and used within the conditioned space 50 or outside the conditioned space 50, thus stably supplying conditioned air to the conditioned space 50. Therefore, an integrated air conditioning device 301 can be obtained that can be used effectively by switching between operating modes: installing the device 301 within the conditioned space 50 containing conditioned air and installing the device 301 outside the conditioned space 50, such as in the field.

[0158] Additionally, as an example, housing 2 has an air inlet 2d and an air outlet 2c separately configured with a specific air inlet 2a and a generated air outlet 2b. In the first setting mode, the conditioned air of the conditioned space 50 flows from the specific air inlet 2a to the first heat exchanger E1 under the action of the first fan F1, where it exchanges heat with the refrigerant and is discharged as conditioned air from the generated air outlet 2b. Meanwhile, external air flows from the air inlet 2d to the second heat exchanger E2 under the action of the second fan F2, where it exchanges heat with the refrigerant that has exchanged heat with the conditioned air through the first heat exchanger E1 and is discharged from the air outlet 2c. In addition, in the second setting mode, the target air flows from the air inlet 2d to the second heat exchanger E2 through the second fan F2, where it exchanges heat with the refrigerant and is discharged as the target air from the air outlet 2c. Meanwhile, the external gas flows from the specific air inlet 2a to the first heat exchanger E1 through the first fan F1, where it exchanges heat with the air that has exchanged heat with the target air through the second heat exchanger E2 and is discharged from the generated air outlet 2b.

[0159] According to the above structure, by using the first and second heat exchangers E1 and E2 separately corresponding to each of the first and second setting modes, conditioned air can be efficiently generated and discharged from the device. Thus, conditioned air can be stably supplied to the conditioned space 50.

[0160] Furthermore, in this embodiment, the control unit C controls the fans in such a way that the rotational speeds of the first fan F1 and the second fan F2 are different from each other. Therefore, the first fan F1 and the second fan F2 can be driven respectively according to the optimal rotational speed corresponding to the drive mode. Thus, the control unit C can be less burdened while stably supplying conditioned air to the conditioned space 50.

[0161] Furthermore, in this embodiment, the control unit C switches between the first fan F1 and the second fan F2 as the controlled fan during fan control. This reduces the control burden on the control unit C while ensuring a stable supply of conditioned air to the conditioned space 50.

[0162] Furthermore, after executing fan control, the control unit C in this embodiment executes air supply control of the first fan F1 and the second fan F2 respectively based on the newly received input information from the input receiving unit 21. According to this structure, even in the device 301 where the control unit C executes fan control and drives the device in either the first drive mode or the second drive mode, during the drive process, the first fan F1 and the second fan F2 can be controlled to supply air to the target space 50 according to the user's requirements, thereby stably supplying regulated air adjusted to an appropriate airflow rate.

[0163] Furthermore, the device 301 of this embodiment is configured such that a first heat exchanger E1 and a second heat exchanger E2 are arranged vertically inside the housing 2. This allows for heat exchange between specific air and refrigerant in each of the heat exchangers E1 and E2 while suppressing unnecessary thermal interference between them. Therefore, the device 301 can stably generate conditioned air according to any one of the first and second drive modes, and any one of the air conditioning modes, either cooling or heating.

[0164] Furthermore, compared to the case where the first heat exchanger E1 and the second heat exchanger E2 are arranged in a horizontal direction, the horizontal dimension of the housing 2 can be suppressed. As a result, while suppressing the arrangement space of the device 301, it is easy to place the device 301 close to the outlet position for exporting conditioned air from the conditioned space 50 or the supply position for supplying conditioned air to the conditioned space 50.

[0165] In addition, the housing 2 of this embodiment has a specific air inlet 2a for introducing specific air into the interior and a generating air outlet 2b for discharging generated air. The control unit C is positioned upstream of the first heat exchanger E1 in the flow direction of the air from the specific air inlet 2a to the generating air outlet 2b.

[0166] According to the above structure, for example, when the device 301 is driven in cooling mode, even if condensation occurs on the first heat exchanger E1 and its surrounding area, the condensed moisture can be prevented from adhering to the control unit C. Furthermore, the control unit C can be air-cooled by introducing specific air from the housing 2 through the specific air inlet 2a. Therefore, the control unit C can be driven stably.

[0167] In addition, as an example, device 301 includes elongated pipe components 3, 4, which are connected to an opening that serves as at least one of a specific air inlet 2a and a generating air outlet 2b and extend from the housing 2 to the outside.

[0168] According to the above structure, by connecting the pipe components 3 and 4 through the openings, the flow direction of the specific air introduced through the specific air inlet 2a can be set so that it does not affect the flow direction of the generated air discharged from the generated air outlet 2b. Therefore, the control unit C can drive the first fan F1 and the second fan F2 under optimal conditions corresponding to the drive mode, and in either drive mode, the pipe components 3 and 4 can stably supply regulating air to the regulating space 50.

[0169] Furthermore, the device 301 of this embodiment is driven in either a heating mode where the temperature of the regulated air is higher than that of the target air, or a cooling mode where the temperature of the regulated air is lower than that of the target air. Therefore, in either the heating or cooling mode, when the device 301 is placed outside the target space 50 and the air in the target space 50 is regulated using the device 301, efficient airflow between the device 301 and the target space 50 can be achieved.

[0170] Thus, the device 301 can be installed and used anywhere, such as outdoors, indoors, or in a vehicle. Furthermore, when the device 301 is installed in the target space 50, it can be protected from the influence of the outdoors. Additionally, when the device 301 is installed in the target space 50 and operated in heating mode, the heat emitted by the device 301 can also heat the air in the target space 50 to a certain extent.

[0171] Alternatively, the specific air inlet 2a and the generated air outlet 2b can also be disposed on the side of the housing 2 (for example, the front 20b). In this case, for example, the specific air inlet 2a and the generated air outlet 2b can be disposed side by side on the upper part of the same side. In this case, the first pipe component 3 can be connected to the specific air inlet 2a, and the second pipe component 4 can be connected to the generated air outlet 2b. In this way, the specific air inlet 2a and the generated air outlet 2b do not necessarily need to be disposed on the upper surface 20a of the housing 2. In addition, pipe components 3 and 4 are not necessary, and pipe components 3 and 4 can be omitted depending on the arrangement method, etc. Hereinafter, the modified examples will be described with a focus on the differences from the embodiment.

[0172] (Modified Example)

[0173] The device 301 in this variation, like the device 301 in the embodiment, includes: a temperature sensor S that measures the temperature of the conditioned air flowing inside the housing 2; and a compressor CP that compresses the refrigerant flowing between the first heat exchanger E1 and the second heat exchanger E2 (see reference). Figure 2As an example, the compressor CP has a compressor motor that generates compression force to compress the refrigerant by being driven to rotate in a predetermined direction. Furthermore, after executing fan control (S3, S4), the control unit C in this modified example, based on newly received input information from the input receiving unit 21 (e.g., information indicating the temperature adjustment of the conditioned air) and temperature information detected by the temperature sensor S, executes compressor control to control the speed of the compressor CP (here, as an example, the speed of the compressor motor; also called the frequency) so that the temperature represented by the aforementioned temperature information is within a predetermined temperature range. Figure 11 This is a flowchart of compressor control during normal operation of the modified device 301.

[0174] Specifically, such as Figure 11 As shown, during normal operation, the control unit C determines whether input information regarding the temperature adjustment instruction has been received via the input receiving unit 21, etc. (S21). In S21, the control unit C continues to perform the determination in S11 until it receives input information regarding the temperature adjustment instruction. In S21, if the control unit C determines that input information regarding the temperature adjustment instruction has been received (S21: Yes), it then determines whether the current drive mode of the device 301 is the first drive mode (S22). In S22, if the control unit C determines that the current drive mode of the device 301 is the first drive mode (S22: Yes), the control unit C then executes compressor control to control the speed of the compressor CP according to the first drive mode (S23).

[0175] In the compressor control (S23) of the first drive mode, the control unit C controls the rotational speed of the compressor CP to ensure that the temperature of the conditioned air flowing inside the housing 2, as detected by the temperature sensor S, is within the target temperature range for a predetermined time. Here, for example, when the air conditioning mode of the device 301 is set to cooling mode and the airflow mode of the conditioned air supplied from the device 301 is set to "low airflow" mode, the volume of conditioned air supplied to the conditioned space 50 per unit time is relatively small. In this case, it takes a certain amount of time to set the conditioned air supplied from the device 301 to the target temperature range. However, for example, by increasing the rotational speed of the compressor CP, the control unit C can improve the heat exchange efficiency of the air based on the heat exchangers E1 and E2. Therefore, even with a small volume of conditioned air, the cooling efficiency of the conditioned space 50 based on the first drive mode can be increased. After completing the execution of the compressor control (S23), the control unit C ends the process.

[0176] On the other hand, in S22, if the control unit C determines that the current drive mode of device 301 is not the first drive mode (S22: No), the control unit C then executes compressor control according to the second drive mode (S24). In the compressor control (S24) under this second drive mode, the control unit C can increase the cooling efficiency of the regulated space 50 based on the second drive mode by, for example, increasing the speed of compressor CP. After completing the execution of compressor control (S24), the control unit C ends the process.

[0177] As described above, according to this modification, even when the volume of conditioning air supplied from device 301 to the conditioning target space 50 is small, for example, by controlling the compressor by varying the rotational speed of compressor CP through control unit C, the heat exchange efficiency of the air based on the first heat exchanger E1 and the second heat exchanger E2 can be adjusted. Thus, in either the first drive mode or the second drive mode, adequately temperature-controlled conditioning air can be supplied to the conditioning target space 50. Furthermore, for example, when the air conditioning mode of device 301 is cooling mode, control unit C can cause low-temperature conditioning air to flow within the housing 2 by executing compressor control. This also effectively cools the heat exchangers E1 and E2 within the housing 2 for dehumidification. Additionally, control unit C can determine in S22 whether the drive mode of device 301 is the second drive mode and reflect the determination result in compressor control (S23, S24).

[0178] This invention is not limited to the above-described embodiments and variations. Its structure and method can be changed, added to, combined with, or deleted without departing from the spirit of this invention. In the first embodiment, an example of using the device 1 outdoors is described. When using an integrated air conditioning unit outdoors, for example, it can reduce the burden of handling drainage from the drain pipe, and compared to installing the device indoors or inside a vehicle, it has the advantage of not requiring installation space for the device. However, this invention is not limited to this; the integrated air conditioning unit can also be used indoors or inside a vehicle.

[0179] Furthermore, the power source of the device 301 in the second embodiment is not limited to a power supply circuit (e.g., a circuit connected to an indoor socket) that is fixedly installed in a building or the like, but may be a portable power source (external power source) such as a battery or a portable generator.

[0180] Furthermore, the functions of the elements described in this specification can be executed using circuits or processing circuits, including: general-purpose processors, special-purpose processors, integrated circuits, ASICs (Application Specific Integrated Circuits), existing circuits, and / or combinations thereof configured or programmed to perform the described functions. Since a processor includes transistors and other circuits, it is considered a processing circuit or circuit. In this invention, a circuit, unit, or means is hardware that performs the listed functions, or hardware programmed to perform the listed functions. The hardware can be the hardware described in this specification, or it can be other known hardware programmed or configured to perform the described functions. Where the hardware is a processor considered a type of circuit, the circuit, means, or unit is a combination of hardware and software, with the software used to construct the hardware and / or processor.

[0181] (Postscript)

[0182] The following technology is achieved through the above-described embodiments and variations.

[0183] (Technology 1)

[0184] An integrated air conditioning unit, comprising:

[0185] The first heat exchanger is used to exchange heat between specific air and refrigerant, the specific air being either the air to be regulated or the outside air;

[0186] A second heat exchanger, separately configured from the first heat exchanger, is used to allow the refrigerant that has exchanged heat with the specific air in the first heat exchanger to exchange heat with the conditioned air and air in the outside air that is not the specific air; and

[0187] The housing integrally houses the first heat exchanger and the second heat exchanger.

[0188] The housing has: a specific air inlet for introducing the specific air into the interior; and a generated air outlet for discharging the generated air produced by heat exchange between the specific air and the refrigerant in the first heat exchanger.

[0189] The specific air inlet and the generated air outlet are configured on the upper part of the housing.

[0190] According to the above structure, when using an integrated air conditioning unit located outside the target space to regulate the air in the target space, even if the outlet position for venting the regulated air from the target space or the supply position for supplying regulated air to the target space is higher than the device, the specific air inlet and the generated air outlet are located on the upper part of the housing. Therefore, for example, it is easy to arrange ductwork components for allowing air to flow between the device and the target space. Thus, the increase in the volume of ductwork components can be suppressed, reducing the workload of ductwork arrangement. As a result, the device can be easily installed. Therefore, even when the integrated air conditioning unit is located outside the target space and the air in the target space is regulated using the device, efficient airflow between the device and the target space is possible.

[0191] Furthermore, since the specific air inlet and the generated air outlet are located on the upper part of the housing, even when the outlet and supply positions are at a higher position compared to the device, the specific air inlet and the generated air outlet can still be brought close to the outlet and supply positions. This suppresses the length of the pipe components, thus preventing the regulated air from being affected by the heat of the external air as it passes through the pipe components. Therefore, a stable air conditioning effect can be obtained.

[0192] (Technology 2)

[0193] As described in Technical 1, in the integrated air conditioning device,

[0194] The specific air inlet and the generated air outlet are disposed on the upper surface of the housing.

[0195] Based on the above structure, it is easier to arrange the ductwork components used to allow air to flow between the device and the space to be regulated. Therefore, it is possible to further reduce the increase in the size of the ductwork components and further reduce the workload of ductwork configuration.

[0196] (Technology 3)

[0197] As described in Technology 1 or Technology 2, in the integrated air conditioning device,

[0198] Inside the housing, the first heat exchanger and the second heat exchanger are arranged in a vertical orientation.

[0199] According to the above structure, compared with the case where the first and second heat exchangers are arranged in a horizontal direction, the horizontal dimension of the housing can be suppressed. As a result, while suppressing the arrangement space of the device, it is easy to place the device close to the outlet position for exporting conditioned air from the conditioned space or the supply position for supplying conditioned air to the conditioned space.

[0200] (Technology 4)

[0201] The integrated air conditioning device as described in any one of techniques 1 to 3 includes:

[0202] At least one electrical component housed within the housing; and

[0203] Wires used to supply electrical power from an external source to the electrical components.

[0204] The wire extends from the inside of the housing to the outside through the specific air inlet.

[0205] According to the above structure, since the wire extends from the inside of the housing to the outside through a specific air inlet, it is easy to position the wire upstream of the first heat exchanger in the direction of airflow. Therefore, for example, when the device is driven in cooling mode, it is possible to prevent condensation from forming on and around the first heat exchanger from adhering to the wire. Thus, the device can be driven stably.

[0206] (Technology 5)

[0207] The integrated air conditioning device as described in any one of techniques 1 to 4 includes:

[0208] At least one electrical component housed within the housing;

[0209] Electrical wires extending from the housing to the outside for supplying electrical power from the outside to the electrical components; and

[0210] A duct component, which connects to an opening serving as at least one of the specific air inlet and the generated air outlet, and extends from the housing to the outside.

[0211] The wire passes through the interior of the conduit component and extends to the exterior from the side of the conduit component opposite to the opening side.

[0212] According to the above structure, since the conduit components can protect the electrical wires, electrical malfunctions caused by moisture such as rain or dew adhering to the wires can be prevented even when the device is installed outdoors, for example. Therefore, the device can be driven stably.

[0213] (Technology 6)

[0214] As described in technical technology 4 or 5, in the integrated air conditioning device, wherein...

[0215] The wire has wiring terminals that can be detachably connected to the electrical components.

[0216] Based on the above structure, electrical connections between wires and electrical components can be easily made by electrically connecting electrical components and wiring terminals. Furthermore, for example, it is possible to easily replace wires of different lengths and specifications.

[0217] (Technology 7)

[0218] The integrated air conditioning device as described in Technique 6 includes:

[0219] A housing terminal is disposed in the housing at a position lower than the connection position between the wiring terminal and the electrical component, is electrically connected to the electrical component, and can be detachably electrically connected to the wiring terminal.

[0220] According to the above structure, by electrically connecting the wiring terminals and electrical components at the connection position, even if the outlet position for venting the regulated air from the regulated space or the supply position for supplying regulated air to the regulated space is at a higher position than the device, power can be easily supplied to the device from the regulated space side via a wire through the outlet position or the supply position. Furthermore, by electrically connecting the wiring terminals and housing terminals, for example, power can be supplied to the device via a wire extending to a position lower than the connection position. Therefore, power can be easily supplied to the device.

[0221] (Technology 8)

[0222] The integrated air conditioning unit as described in technique 6 or 7 includes:

[0223] Electrical component terminals housed within the housing are detachably electrically connected to the wiring terminals, thereby electrically connecting the wiring terminals to the electrical components.

[0224] The specific air inlet is disposed on the upper surface of the housing.

[0225] When viewed from above, the electrical component terminals are exposed from the specific air inlet.

[0226] According to the above structure, the electrical connection between the wiring terminals and the electrical component terminals can be disconnected through a specific air inlet located on the upper surface of the housing. Therefore, the convenience for the user when electrically connecting the wiring terminals to the electrical components is improved.

[0227] (Technology 9)

[0228] The integrated air conditioning device as described in any one of techniques 1 to 8 includes:

[0229] A first fan capable of supplying air to the first heat exchanger;

[0230] A second fan capable of supplying air to the second heat exchanger; and

[0231] The control unit is capable of controlling the first fan and the second fan.

[0232] The control unit is positioned upstream of the first heat exchanger in the direction of air flow from the specific air inlet to the generated air outlet.

[0233] According to the above structure, since the control unit is positioned upstream of the first heat exchanger in the direction of air flow from the specific air inlet to the generated air outlet, for example, when the device is driven in cooling mode, it is possible to suppress the adhesion of condensation moisture generated in and around the first heat exchanger to the control unit. Furthermore, the control unit can be air-cooled by introducing specific air from the specific air inlet into the housing. Therefore, the control unit can be driven stably.

[0234] (Technology 10)

[0235] The integrated air conditioning device as described in any one of techniques 1 to 9, wherein...

[0236] The housing has: an air inlet for introducing the external gas into the interior and an air outlet for discharging the external gas after heat exchange.

[0237] The air inlet and the air outlet are located on the side of the housing.

[0238] Based on the above structure, the air inlet and air outlet can be configured to prevent interference with specific air inlets and outlets. Therefore, the device can be driven stably.

[0239] (Technology 11)

[0240] The integrated air conditioning device as described in any one of techniques 1 to 10, wherein...

[0241] The specific air is the air to be conditioned, and the generated air is the conditioned air generated by exchanging heat between the air to be conditioned and the refrigerant.

[0242] It can be driven in either heating or cooling mode, wherein,

[0243] The heating mode is a mode in which the temperature of the regulated air is higher than that of the target air, and the cooling mode is a mode in which the temperature of the regulated air is lower than that of the target air.

[0244] Based on the above structure, in either the heating mode or the cooling mode, when the integrated air conditioning unit is placed outside the space to be conditioned and the air in the space to be conditioned is conditioned using the unit, air can flow efficiently between the unit and the space to be conditioned.

[0245] (Technology 12)

[0246] The integrated air conditioning device as described in Technology 1 further includes:

[0247] A first fan capable of supplying air to the first heat exchanger;

[0248] A second fan capable of supplying air to the second heat exchanger; and

[0249] The control unit that controls the first fan and the second fan.

[0250] The first heat exchanger, the second heat exchanger, the first fan, the second fan, and the control unit are integrally housed within the housing.

[0251] The air conditioning device is configured to switch between a first setting mode and a second setting mode, wherein the first setting mode is a mode in which the specific air inlet and the generated air outlet lead to the space to be conditioned, and the second setting mode is a mode in which the specific air inlet and the generated air outlet lead to the outside of the space to be conditioned.

[0252] Based on the above structure, an integrated air conditioning device can be provided that can be used by switching between a first setting mode and a second setting mode. The first setting mode is used when the device is installed outside the space to be conditioned, such as outdoors, and the second setting mode is used when the device is installed inside the space to be conditioned, where the air to be conditioned exists.

[0253] (Technology 13)

[0254] As described in Technical 12, in the integrated air conditioning device,

[0255] The housing has an air inlet and an air outlet separately configured with the specific air inlet and the generated air outlet.

[0256] In the first configuration mode, the conditioned air in the conditioned space flows from the specific air inlet to the first heat exchanger under the action of the first fan, exchanges heat with the refrigerant in the first heat exchanger, and is discharged as conditioned air from the generated air outlet. Meanwhile, the external air flows from the air inlet to the second heat exchanger under the action of the second fan, exchanges heat with the refrigerant that has exchanged heat with the conditioned air in the first heat exchanger, and is discharged from the air outlet.

[0257] In the second setting mode, the target air flows from the air inlet to the second heat exchanger under the action of the second fan, exchanges heat with the refrigerant in the second heat exchanger, and is discharged from the air outlet as the target air. Meanwhile, the outside air flows from the specific air inlet to the first heat exchanger under the action of the first fan, exchanges heat with the refrigerant that has exchanged heat with the target air through the second heat exchanger, and is discharged from the generated air outlet.

[0258] According to the above structure, by using the first and second heat exchangers separately corresponding to each of the first and second setting modes, conditioned air can be efficiently generated and discharged from the device. This allows for a stable supply of conditioned air to the conditioned space.

[0259] (Technology 14)

[0260] As described in technical specifications 12 or 13, in the integrated air conditioning device,

[0261] The control unit controls the rotational speeds of the first fan and the second fan to make them different from each other.

[0262] Based on the above structure, the first and second fans can be driven at optimal speeds corresponding to the drive mode of the device. Therefore, it is possible to stably supply conditioned air to the conditioned space while reducing the control burden on the control unit.

[0263] (Technology 15)

[0264] As described in technical specifications 12 or 13, in the integrated air conditioning device,

[0265] The control unit switches between the first fan and the second fan, making one of them the object of control.

[0266] Based on the above structure, by switching and selecting the fan as the controlled object, the control burden of the control unit can be reduced, and the controlled air can be stably supplied to the controlled space.

[0267] (Technology 16)

[0268] The integrated air conditioning device as described in any one of techniques 12 to 15 includes:

[0269] A temperature sensor is used to measure the temperature of the regulated air flowing inside the housing; and

[0270] A compressor for compressing the refrigerant flowing between the first heat exchanger and the second heat exchanger.

[0271] The control unit executes compressor control based on the temperature information detected by the temperature sensor, thereby controlling the compressor speed to keep the temperature indicated by the temperature information within a specified temperature range.

[0272] According to the above structure, even when the volume of conditioned air supplied from the device to the conditioned space is small, for example, by executing compressor control through the control unit to change the compressor speed, the heat exchange efficiency of the air based on the first and second heat exchangers can be adjusted. Therefore, in either the first drive mode or the second drive mode, sufficiently temperature-controlled conditioned air can be supplied to the conditioned space. Furthermore, for example, when the device's air conditioning mode is cooling mode, by executing compressor control through the control unit, low-temperature conditioned air can flow within the housing. This also effectively cools the heat exchangers within the housing for dehumidification.

[0273] (Technology 17)

[0274] The integrated air conditioning device as described in any one of techniques 12 to 16, wherein...

[0275] Inside the housing, the first heat exchanger and the second heat exchanger are arranged in a vertical orientation.

[0276] According to the above structure, since the first heat exchanger and the second heat exchanger are arranged side by side in the vertical direction, unnecessary thermal influence between the heat exchangers can be suppressed, and heat exchange between specific air or non-specific air and refrigerant can be carried out in each heat exchanger. Therefore, the device can stably generate conditioned air according to any one of the first and second drive modes, and according to any one of the cooling and heating modes.

[0277] Furthermore, compared to arranging the first and second heat exchangers horizontally, the horizontal dimension of the housing can be controlled. As a result, while minimizing the space required for the device's placement, it can be easily positioned close to either the outlet location for conditioned air from the conditioned space or the supply location for conditioned air to the conditioned space.

[0278] (Technology 18)

[0279] As described in Technical 12, in the integrated air conditioning device,

[0280] The control unit is positioned upstream of the first heat exchanger in the direction of air flow from the specific air inlet to the generated air outlet.

[0281] According to the above structure, the control unit is positioned upstream of the first heat exchanger in the direction of air flow from the specific air inlet to the generated air outlet. Therefore, for example, when the device is driven in cooling mode, even if condensation occurs on and around the first heat exchanger, the adhesion of condensed moisture to the control unit can be suppressed. Furthermore, the control unit can be air-cooled by introducing specific air into the housing from the specific air inlet. Therefore, the control unit can be driven stably.

[0282] (Technology 19)

[0283] The integrated air conditioning device as described in Technique 18 includes:

[0284] A duct component that connects to an opening that serves as at least one of the specific air inlet and the generated air outlet and extends from the housing to the outside.

[0285] According to the above structure, by connecting the pipe component to the above opening, the flow direction of the specific air introduced by the specific air inlet can be separated from the flow direction of the generated air discharged from the generated air outlet. Therefore, the first fan and the second fan can be driven under conditions corresponding to the method of using the device in the controlled space where the controlled air is located, and the method of using the device outside the controlled space, such as in the field, and in either driving mode, the pipe component can stably supply controlled air to the controlled space.

[0286] This invention is not limited to the embodiments described above. Its structure can be modified, added to, or deleted without departing from the spirit of this invention. Furthermore, the power source for the integrated air conditioning device is not limited to a power circuit (such as a circuit connected to an indoor socket) fixedly installed in a building, etc., but can also be a portable power source (external power source) such as a battery, or a portable generator.
