[0009] Hereinafter, an embodiment will be described with reference to the drawings. (Embodiment) FIG. 1 is a front view of an all-in-one air conditioning unit (hereinafter, simply referred to as "unit") 1 according to an embodiment. FIG. 2 is a functional block diagram showing the configuration of the unit 1 shown in FIG. 1. As shown in FIGS. 1 and 2, the unit 1 includes a housing 2 and long duct members 3 and 4 detachably connected to the housing 2. The unit 1 further 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. The unit 1 is driven (operated) based on one of the air conditioning modes, a cooling mode and a heating mode. The unit 1 is driven based on one of the following air flow modes: a "high air flow" mode in which the amount of conditioned air flow is high, a "medium air flow" mode in which the amount of conditioned air flow is medium, and a "low air flow" mode in which the amount of conditioned air flow is low. The unit 1 according to this embodiment is portable enough to be carried by a person and used at a predetermined location.

[0010] As will be described in more detail, the control unit C of the device 1 performs blower control to individually control the first blower F1 and the second blower F2 so that the drive mode is switched between a predetermined first drive mode and a predetermined second drive mode related to the installation state of the device 1 based on the input information received by the input receiving unit 21, in accordance with the installation state of the device 1.

[0011] As a result, the air sent to the first heat exchanger E1 and the second heat exchanger E2 switches between the air to be conditioned and the outside air between the first drive mode and the second drive mode. Therefore, the device 1 can be used by switching the drive mode in either a mode in which the device 1 is installed and used inside the space to be conditioned 50 filled with the air to be conditioned (see FIG. 6), or a mode in which the device 1 is installed and used outside the space to be conditioned 50, such as outdoors (see FIG. 3).

[0012] The housing 2 integrally houses the first heat exchanger E1, the second heat exchanger E2, the first fan F1, the second fan F2, and the control unit C. The housing 2 of this embodiment further houses a compressor CP, a pressure reducer CR, a switching valve V, and a refrigerant pipe R. As an example, the housing 2 has a rectangular parallelepiped appearance, with the front surface 20b and the back surface 20c being larger than the pair of side surfaces 20d, 20e. This reduces the depth dimension (the dimension perpendicular to the paper surface of FIG. 1) of the housing 2 compared to the width dimension (the dimension horizontally to the paper surface of FIG. 1). Therefore, the device 1 can be easily installed close to the space 50 to be conditioned, facing in the direction perpendicular to the front surface 20b and the back surface 20c (the depth direction).

[0013] The first heat exchanger E1 exchanges heat with a refrigerant using specific air, which is either air to be conditioned supplied from the outside or outside air supplied from the outside. The air to be conditioned can be, for example, air in a conditioned space 50 inside a building such as a house, but is not limited to this and may be, for example, air in a conditioned space 50 inside a vehicle such as an automobile. The outside air can be, for example, outdoor air, but is not limited to this and may be, for example, air in a space other than the conditioned space 50 inside a building or a vehicle. The first fan F1 sends air to the first heat exchanger E1. The first fan F1 has a fan and an electric motor M1 that rotates the fan. The first fan F1 includes, for example, a sirocco fan.

[0014] The second heat exchanger E2 is disposed separately from the first heat exchanger E1 and exchanges heat with the refrigerant between the air to be conditioned and the outside air, which is different from the air sent to the first heat exchanger E1. The second fan F2 sends air to the second heat exchanger E2. The second fan F2 has a fan and an electric motor M2 that rotates the fan. The second fan F2 includes, for example, a propeller fan.

[0015] In the device 1 of this embodiment, a first heat exchanger E1 and a second heat exchanger E2 are arranged side by side in the vertical direction inside the housing 2. As an example, the first heat exchanger E1 and the second heat exchanger E2 are arranged in positions where they overlap each other when viewed from the vertical direction. As another example, the first heat exchanger E1 is arranged above the second heat exchanger E2. A partition wall 2f is arranged between the first heat exchanger E1 and the second heat exchanger E2 to suppress unnecessary mixing of air. The partition wall 2f extends horizontally inside the housing 2.

[0016] The refrigerant pipe R circulates a refrigerant inside the casing 2. As shown in FIG. 2, the refrigerant pipe R includes a plurality of pipes RP1 to RP5. The pipe RP1 connects the second heat exchanger E2 and the pressure reducer CR. The pipe RP2 connects the pressure reducer CR and the first heat exchanger E1. The pipe RP3 connects the first heat exchanger E1 and the switching valve V. The pipe RP4 connects the switching valve V and the compressor CP. The pipe RP5 connects the compressor CP and the second heat exchanger E2. In the device 1, the refrigerant circulates through the refrigerant pipe R among the heat exchangers E1 and E2, the compressor CP, and the pressure reducer CR.

[0017] The switching valve V switches the flow direction of the refrigerant flowing through the refrigerant pipe R. The switching valve V is, for example, a four-way valve, but is not limited thereto. The switching valve V is, for example, a solenoid valve. The device 1 further includes various valve devices, strainers, and the like, as appropriate. The control unit C controls various electrical components provided in the device 1, including the first fan F1 and the second fan F2. As an example, the control unit C controls the electric motors M1 and M2, the compressor CP, the pressure reducer CR, and the switching valve V. The control unit C includes a calculation unit and a memory unit. The calculation unit performs calculations based on a predetermined control program. This control program includes a program that causes the control unit C to execute the fan control described below. The memory unit stores the control program and reads it out by the calculation unit. The calculation unit is implemented by at least one processor such as a CPU. The memory unit is implemented by at least one memory such as a ROM or RAM. The pressure reducer CR reduces the pressure of the refrigerant flowing through the refrigerant pipe R.

[0018] The pressure reducer CR reduces the pressure of the refrigerant and includes, for example, a pressure reducing valve. The drain pipe D extends from the lower part of the housing 2 to the outside and drains water generated inside the housing 2 to the outside. The bottom surface of the housing 2 is provided with an inclined portion 2e that guides water collected at the bottom of the housing 2 toward the drain pipe D.

[0019] The device 1 also includes at least one electrical component housed in the housing 2, a power line L that supplies externally supplied power to the electrical component, and a power supply unit P that adjusts the power. In this embodiment, the at least one electrical component includes, for example, an electric motor M1 of the first fan F1, an electric motor M2 of the second fan F2, and a control unit C. The device 1 also includes, for example, a temperature sensor S connected to the control unit C that detects the temperature of specific air taken into the housing 2, and an input receiving unit 21 that receives user inputs such as an on / off operation for the device 1 and an operation to switch the driving mode. The input receiving unit 21 has, for example, an input button that the user operates. Instead of or in addition to the input receiving unit 21, the device 1 may include a communication receiving unit that receives user operations via a mobile device such as a smartphone or a remote control.

[0020] Here, the housing 2 has a specific air intake port 2a and a generated air outlet 2b. The specific air intake port 2a takes in specific air, which is either air to be conditioned or outside air. The generated air outlet 2b discharges the generated air generated by causing the first heat exchanger E1 to exchange heat with a refrigerant. When the device 1 is installed outside the space 50 to be conditioned, the specific air is the air to be conditioned, and the generated air is conditioned air. Also, when the device 1 is installed inside the space 50 to be conditioned, the specific air is outside air. The specific air intake port 2a and the generated air outlet 2b are located at the top of the housing 2. In this embodiment, the specific air intake port 2a and the generated air outlet 2b are located on the top surface 20a of the housing 2, as an example.

[0021] The housing 2 also has an air inlet 2d and an air outlet 2c that are arranged separately from the specific air inlet 2a and the generated air outlet 2b. As an example, when the device 1 is installed outside the space 50 to be conditioned, the air inlet 2d takes in outside air into the housing 2, and the air outlet 2c discharges the heat-exchanged outside air to the outside of the housing 2. When the device 1 is installed inside the space 50 to be conditioned, the air inlet 2d takes in the air to be conditioned into the housing 2, and the air outlet 2c discharges the conditioned air to the outside of the housing 2. In this embodiment, the air inlet 2d is arranged on the back surface 20c of the housing 2, and the air outlet 2c is arranged on the front surface 20b of the housing 2. In this manner, in the device 1, the specific air inlet 2a and the generated air outlet 2b are arranged on the same surface of the housing 2, while the air inlet 2d and the air outlet 2c are arranged on different surfaces of the housing 2.

[0022] The device 1 also includes a long duct member that is connected to at least one of the specific air intake port 2a and the generated air discharge port 2b and extends to the outside of the housing 2. Specifically, the device 1 of this embodiment includes, as an example, a first duct member 3 connected to the specific air intake port 2a and a second duct member 4 connected to the generated air discharge port 2b. The duct members 3 and 4 are flexible tubular members that are configured to be flexible and bendable in the longitudinal direction. As an example, the duct members 3 and 4 include bellows pipes.

[0023] One end 3a of the first duct member 3 is detachably connected to the specific air intake port 2a. One end 4a of the second duct member 4 is detachably connected to the generated air discharge port 2b. The other ends 3b, 4b of the duct members 3, 4 are arranged so that they open toward the outside or inside of the conditioned space 50. It is desirable that the other ends 3b, 4b of the duct members 3, 4 are arranged with the distance between them or the direction of air flow adjusted so that the air flowing through the openings 3c, 4c of the duct members 3, 4 does not directly interfere with each other.

[0024] Next, a method for installing the device 1 outside the space 50 to be conditioned will be described. Fig. 3 is a diagram showing an installation mode (an installation mode outside the space 50 to be conditioned) of the device 1 in Fig. 1. As shown in Fig. 3, when installing the device 1 outside the space 50 to be conditioned (outdoors as an example here), the user places the device 1 near the space 50 to be conditioned. At this time, the user installs the device 1 while ensuring a certain distance from the wall 51 that separates the space 50 to be conditioned from other spaces so that outside air can be easily taken into the housing 2 from the air intake port 2d.

[0025] The user also positions the openings 3c, 4c of the other ends 3b, 4b of the duct members 3, 4 facing the target space 50. The user may directly fix the other ends 3b, 4b of the duct members 3, 4 to the wall 51, or may indirectly fix them to the wall 51 using a predetermined jig, such as a support structure 52 attached to the wall 51. The support structure 52, for example, includes a plate-shaped member and supports the other ends 3b, 4b of the duct members 3, 4 so that no gap is created between the outer periphery of the other ends 3b, 4b and the target space 50. The user also electrically connects the terminals of the power line L to, for example, a power supply circuit (in the example of FIG. 3 ) located on the target space 50 side. This ensures power supply for the device 1. Furthermore, installing the device 1 outdoors can, for example, facilitate heat dissipation during operation of the device 1 and reduce the burden of drainage treatment from the drain pipe D. Furthermore, installation space for the device 1 can be easily secured.

[0026] Next, a method for installing the device 1 in the space 50 to be conditioned will be described. Fig. 4 is a diagram showing the installation mode of the device 1 in Fig. 1 (installation mode in the space 50 to be conditioned). As shown in Fig. 4, when installing the device 1 in the space 50 to be conditioned, the user installs the device 1 while ensuring a certain distance from the wall 51 so that the air to be conditioned can be easily taken into the housing 2 from the air intake 2d. The user also adjusts the drain position of the drain pipe D so that moisture from the drain pipe D is discharged to a specified drain location outside the space 50 to be conditioned.

[0027] The user also positions the openings 3c, 4c of the other ends 3b, 4b of the duct members 3, 4 facing outside the space 50 to be harmonized (outdoors, as an example here). As in Fig. 3, the user may fix the other ends 3b, 4b of the duct members 3, 4 directly to the wall 51, or may fix them indirectly to the wall 51 using a predetermined jig such as a support structure 52 attached to the wall 51. The user also electrically connects the terminal of the power line L to, for example, a power supply circuit arranged on the side of the space 50 to be harmonized (in the example of Fig. 4, an outlet provided indoors).

[0028] After making the above settings, the user sets the drive mode of the device 1 to either the first drive mode or the second drive mode depending on the installation manner of the device 1. Here, the first drive mode is a drive mode in which the first fan F1 blows the air to be conditioned toward the first heat exchanger E1, causing the first heat exchanger E1 to exchange heat with the refrigerant and generate conditioned air from the air to be conditioned, and the second fan F2 blows outside air toward the second heat exchanger E2, causing the second heat exchanger E2 to exchange heat with the refrigerant that has exchanged heat with the air to be conditioned by the first heat exchanger E1. The first drive mode of this embodiment corresponds to a manner in which the device 1 is installed and used outside the space 50 to be conditioned, such as outdoors (the installation manner of FIG. 3).

[0029] Furthermore, the second drive mode is a drive mode in which the air to be conditioned is blown by the second fan F2 toward the second heat exchanger E2, causing the second heat exchanger E2 to exchange heat with the refrigerant and generate conditioned air from the air to be conditioned, and outside air is blown by the first fan F1 toward the first heat exchanger E1, causing the first heat exchanger E1 to exchange heat with the refrigerant that has exchanged heat with the air to be conditioned by the second heat exchanger E2. The second drive mode of the present embodiment corresponds to a mode in which the device 1 is installed and used within the space 50 to be conditioned (the installation mode in FIG. 4).

[0030] The setting of the drive mode of the device 1 is set, for example, based on a drive mode setting instruction from the user input to the input receiving unit 21. Furthermore, the user sets the air conditioning mode of the device 1 to either the cooling mode or the heating mode and drives the device 1.

[0031] Here, when the user sets the drive mode of the device 1 to the first drive mode or the second drive mode, the control unit C executes a predetermined fan control. This fan control will be explained below. FIG. 5 is a flow diagram of the fan control at the initial stage of drive of the device 1 in FIG. 1. The initial stage of drive here refers to, for example, the period from when the device 1 starts to drive until the control unit C first determines whether the drive mode of the device 1 is the first mode. In the following description, "S" indicates a step, and "Yes" or "No" following ":" indicates the determination result at the step described immediately before ":".

[0032] 5, at the beginning of operation of the device 1, the control unit C determines whether input information has been received to set the drive mode of the device 1 to either the first drive mode or the second drive mode (S1). The input information is, for example, information input to the device 1 through the input receiving unit 21, but the method for receiving the input information is not limited to this.

[0033] The control unit C continues the process of S1 until it determines that input information has been received in S1. If the control unit C determines that input information has been received in S1 (S1: Yes), it then determines whether the drive mode set in the received input information is the first drive mode (S2). If the control unit C determines that the drive mode set in the received input information is the first drive mode (S2: Yes), it then performs fan control to individually control the fans F1 and F2 based on the first drive mode (S3).

[0034] In the fan control in the first drive mode (S3), the controller C controls the first fan F1 and the second fan F2 to have different rotation speeds, for example. Specifically, in the fan control in the first drive mode (S3), the controller C controls the electric motors M1 and M2 so that the rotation speed of the first fan F1 is higher than the rotation speed of the second fan F2. Alternatively, in the fan control in the first drive mode (S3), the controller C may switch the fan to be controlled between the first fan F1 and the second fan F2. In this case, the controller C may control the first fan F1 and stop control of the second fan F2. After completing the fan control in the first drive mode (S3), the controller C ends the flow.

[0035] On the other hand, if the control unit C determines in S2 that the drive mode of the setting instruction is not the first drive mode (S2: No), the control unit C then performs blower control to individually control the blowers F1 and F2 based on the second drive mode (S4).

[0036] In the fan control (S4) in the second drive mode, the controller C also controls the rotation speeds of the first fan F1 and the second fan F2 to be different from each other, for example. Specifically, in the fan control (S4) in the second drive mode, the controller C controls the electric motors M1 and M2 to increase the rotation speed of the second fan F2 above the rotation speed of the first fan F1. Alternatively, in the fan control (S4) in the second drive mode, the controller C may switch the fan to be controlled between the first fan F1 and the second fan F2. In this case, the controller C may control the second fan F2 and stop controlling the first fan F1. After completing the fan control (S4) in the second drive mode, the controller C ends the flow. Through the above control by the controller C, appropriately temperature-adjusted conditioned air is stably supplied to the conditioned space 50 even when the installation configurations of the devices 1 are different.

[0037] Next, the airflow control performed by the control unit C during normal operation, which is the operation after the initial operation of the device 1 (after the fan control (S3, S4) has been executed), will be described. After executing the fan control (S3, S4), the control unit C executes airflow control to individually control the first fan F1 and the second fan F2 based on input information (for example, information on an instruction to adjust the air volume) newly received by the input receiving unit 21. Figure 6 is a flow diagram of the airflow control during normal operation of the device 1 of Figure 1.

[0038] 6, during normal operation, the control unit C determines whether input information regarding an air volume adjustment instruction has been received via the input receiving unit 21 or the like (S11). In S11, the control unit C continues the determination in S11 until input information regarding an air volume adjustment instruction is received. If the control unit C determines in S11 that input information regarding an air volume adjustment instruction has been received (S11: Yes), it then determines whether the current drive mode of the device 1 is the first drive mode (S12). If the control unit C determines in S12 that the current drive mode of the device 1 is the first drive mode (S12: Yes), it then performs air blowing control to individually control the air volumes of the fans F1 and F2 based on the first drive mode (S13).

[0039] In the air blowing control (S13) in the first drive mode, the controller C controls the first fan F1 and the second fan F2 to have different rotation speeds, for example. Specifically, in the air blowing control (S13) in the first drive mode, the controller C controls the electric motors M1 and M2, for example, to increase the rotation speed of the first fan F1 to be higher than the rotation speed of the second fan F2. Alternatively, in the air blowing control (S13) in the first drive mode, the controller C may switch the fan to be controlled between the first fan F1 and the second fan F2. In this case, in the air blowing control (S13) in the first drive mode, the controller C may control the first fan F1 and stop control of the second fan F2, for example. After completing the air blowing control (S13), the controller C ends the flow.

[0040] On the other hand, if the controller C determines in S12 that the current drive mode of the device 1 is not the first drive mode (S12: No), the controller C then performs air blowing control to individually control the fans F1 and F2 based on the second drive mode (S14). In this air blowing control in the second drive mode (S14), the controller C also controls the first fan F1 and the second fan F2 to have different rotation speeds, for example. Specifically, in the air blowing control in the heating mode (S14), the controller C controls the electric motors M1 and M2 so that the rotation speed of the second fan F2 is higher than the rotation speed of the first fan F1. Alternatively, in the air blowing control in the heating mode (S14), the controller C may switch the fan to be controlled between the first fan F1 and the second fan F2. In this case, in the air blowing control (S14) in the second drive mode, the control unit C may control, for example, the second fan F2 and stop control of the first fan F1. After completing the air blowing control (S14), the control unit C ends the flow.

[0041] By the control of the control unit C described above, when the device 1 is operating in either the first or second driving mode, conditioned air whose temperature has been appropriately adjusted in accordance with the user's request is stably supplied to the space 50 to be conditioned.

[0042] For example, when the drive mode is the first drive mode and the air conditioning mode is the cooling mode, if the user issues an instruction to adjust the airflow rate to the device 1, for example, by operating the input buttons on the input receiving unit 21 or a mobile device such as a smartphone or a remote control, the control unit C executes fan control to control the rotation speed of the first fan F1 based on the instruction (S3). At this time, if it is necessary to increase the airflow rate of the first fan F1, the control unit C increases the rotation speed of the first fan F1. On the other hand, when the control unit C executes fan control (S3) for the second fan F2 that generates a flow of outside air inside the housing 2, the control unit C can control the rotation speed of the second fan F2 to an appropriate rotation speed depending on the state of the refrigerant, the outside temperature, etc., independently of the user's instruction to adjust the airflow rate.

[0043] Furthermore, for example, when the drive mode is the second drive mode and the air conditioning mode is the cooling mode, if the user issues an instruction to adjust the airflow rate to the device 1 using a portable device such as a remote control, the control unit C executes fan control (S4) to control the rotation speed of the second fan F2 based on the instruction. At this time, if it is necessary to increase the airflow rate of the second fan F2, the control unit C increases the rotation speed of the second fan F2. On the other hand, when the control unit C executes fan control (S4) for the first fan F1 that generates a flow of outside air within the housing 2, the control unit C can control the rotation speed of the first fan F1 to an appropriate rotation speed depending on the state of the refrigerant, the outside temperature, etc., independently of the user's instruction to adjust the airflow rate. In this way, in the device 1, of the first fan F1 and the second fan F2, the fan controlled by the control unit C to blow conditioned air into the conditioned space 50 is switched between the first drive mode and the second drive mode.

[0044] In addition, in S2, the control unit C may determine whether the drive mode of the device 1 is the second drive mode or not, and reflect the determination result in the blower control (S3, S4), and in S12, may determine whether the drive mode of the device 1 is the second drive mode or not, and reflect the determination result in the blower control (S13, S14).

[0045] Next, the inside of the device 1 during operation will be described. When the operation mode is the first operation mode and the air conditioning mode is the cooling mode, the second fan F2 is driven, causing outside air to be taken into the interior of the housing 2 through the air inlet 2d. Thereafter, in the second heat exchanger E2, the refrigerant exchanges heat with the outside air and is liquefied. The outside air flows through the interior of the housing 2 from the air inlet 2d toward the air outlet 2c. After heat exchange, the outside air is discharged to the outside of the housing 2 through the air outlet 2c. At this time, because the air outlet 2c faces away from the wall 51 of the housing 2, the outside air discharged from the air outlet 2c is prevented from hitting the wall 51.

[0046] The liquefied refrigerant is sent to the pressure reducer CR through the pipe RP1. The pressure reducer CR reduces the pressure of the liquefied refrigerant. The liquefied refrigerant is sent to the first heat exchanger E1 through the pipe RP2.

[0047] Furthermore, when the first fan F1 is driven, the air to be conditioned is taken into the housing 2 from the specific air intake port 2a through the first duct member 3. Then, in the first heat exchanger E1, the air to be conditioned is cooled by heat exchange with the liquefied refrigerant. This generates conditioned air. The conditioned air is discharged from the generated air discharge port 2b through the second duct member 4 into the space to be conditioned 50. As a result of this heat exchange in the first heat exchanger E1, the refrigerant evaporates.

[0048] The vaporized refrigerant is sent to the compressor CP through the pipe RP3, the switching valve V, and the pipe RP4. The compressor CP compresses and discharges the vaporized refrigerant. The compressed refrigerant returns to the second heat exchanger E2 through the switching valve V and the pipe RP5.

[0049] Furthermore, when the drive mode is the first drive mode and the air conditioning mode is the heating mode, the second fan F2 is driven, causing outside air to be taken into the interior of the casing 2 through the air inlet 2d. Thereafter, in the second heat exchanger E2, the refrigerant exchanges heat with the outside air and vaporizes. The outside air flows through the interior of the casing 2 from the air inlet 2d toward the air outlet 2c. After heat exchange, the outside air is discharged to the outside of the casing 2 through the air outlet 2c. The vaporized refrigerant is sent to the compressor CP through the piping RP4 and the switching valve V. The compressor CP compresses and discharges the vaporized refrigerant. The compressed refrigerant is sent to the first heat exchanger E1 through the piping RP5, the switching valve V, and the piping RP3.

[0050] Furthermore, when the first fan F1 is driven, the air to be conditioned is taken into the housing 2 from the specific air intake port 2a through the first duct member 3. Then, in the first heat exchanger E1, the air to be conditioned 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 duct member 4 into the space 50 to be conditioned. As a result of this heat exchange in the first heat exchanger E1, the refrigerant is liquefied.

[0051] The liquefied refrigerant is sent to the pressure reducer CR through the pipe RP2. The refrigerant is decompressed by the pressure reducer CR and becomes a two-phase gas-liquid refrigerant. The two-phase gas-liquid refrigerant returns to the second heat exchanger E2 through the pipe RP1. Moisture such as condensation generated inside the housing 2 during operation of the device 1 is discharged to the outside of the housing 2 through the drain pipe D.

[0052] When the drive mode is the second drive mode and the air conditioning mode is the cooling mode, the first fan F1 is driven, and outside air is taken into the housing 2 from the specific air intake port 2a through the first duct member 3. Then, in the first heat exchanger E1, the outside air exchanges heat with the vaporized refrigerant. After the heat exchange, the outside air is discharged from the generated air discharge port 2b through the second duct member 4 to the outside of the conditioned space 50. As a result of this heat exchange in the first heat exchanger E1, the refrigerant is liquefied.

[0053] The liquefied refrigerant is sent to the pressure reducer CR through the pipe RP2. The pressure reducer CR reduces the pressure of the liquefied refrigerant. The reduced pressure and liquefied refrigerant is sent to the second heat exchanger E2 through the pipe RP1.

[0054] Furthermore, as the second fan F2 is driven, air to be conditioned is taken into the interior of the housing 2 through the air intake port 2d. Thereafter, in the second heat exchanger E2, the air to be conditioned is cooled by heat exchange with the liquefied refrigerant. This generates conditioned air. The conditioned air is discharged from the air discharge port 2c into the space 50 to be conditioned. As a result of this heat exchange in the second heat exchanger E2, the refrigerant evaporates.

[0055] The vaporized refrigerant is sent to the compressor CP through the pipe RP5 and the switching valve V. The compressor CP compresses and discharges the vaporized refrigerant. The compressed refrigerant returns to the first heat exchanger E1 through the switching valve V and the pipe RP4.

[0056] Furthermore, when the drive mode is the second drive mode and the air conditioning mode is the heating mode, the first fan F1 is driven, and outside air is taken into the housing 2 from the specific air intake 2a through the first duct member 3. Then, in the first heat exchanger E1, the refrigerant exchanges heat with the outside air and evaporates. After heat exchange, the outside air is discharged from the produced air outlet 2b through the second duct member 4 to the outside of the conditioned space 50.

[0057] The vaporized refrigerant is sent to the compressor CP through the pipe RP3, the switching valve V, and the pipe RP4. The compressor CP compresses and discharges the vaporized refrigerant. The compressed refrigerant is sent to the second heat exchanger E2 through the pipe RP5 and the switching valve V.

[0058] Furthermore, as the second fan F2 is driven, air to be conditioned is taken into the housing 2 through the air inlet 2d. Thereafter, in the second heat exchanger E2, the air to be conditioned is heated through heat exchange with the vaporized refrigerant. This generates conditioned air. The conditioned air is discharged from the air outlet 2c into the space 50 to be conditioned. As a result of this heat exchange in the second heat exchanger E2, the refrigerant is liquefied.

[0059] The liquefied refrigerant is sent to the pressure reducer CR through the pipe RP1. The refrigerant is decompressed by the pressure reducer CR and becomes a two-phase gas-liquid refrigerant. The two-phase gas-liquid refrigerant returns to the first heat exchanger E1 through the pipe RP2. Moisture such as condensation generated inside the housing 2 during operation of the device 1 is discharged to the outside of the housing 2 through the drain pipe D.

[0060] As described above, the control unit C of the device 1 executes fan control to individually control the first fan F1 and the second fan F2 so as to switch the drive mode between the first drive mode and the second drive mode based on input information received by the input receiving unit 21. This allows the drive mode of the device 1 to be switched between the first drive mode and the second drive mode, and the heat exchanger that exchanges heat between the air to be conditioned and the outside air to be switched between the first heat exchanger E1 and the second heat exchanger E2.

[0061] For this reason, heat exchangers E1 and E2 can be allocated to correspond to the mode in which the device 1 is installed and used inside the space to be conditioned 50, and the mode in which the device 1 is installed and used outside the space to be conditioned 50, respectively, and the air to be conditioned can be stably supplied to the space to be conditioned 50. Therefore, an all-in-one air conditioning device 1 can be obtained that can be used well by switching the drive mode between the mode in which the device 1 is installed and used inside the space to be conditioned 50 where the air to be conditioned exists, and the mode in which the device 1 is installed and used outside the space to be conditioned 50, such as outdoors.

[0062] Furthermore, in the fan control, the control unit C of this embodiment controls the first fan F1 and the second fan F2 so that their rotation speeds are different from each other. This allows the first fan F1 and the second fan F2 to be driven independently based on the optimal rotation speed according to the drive mode. Therefore, it is possible to provide a stable supply of conditioned air to the conditioned space 50 while reducing the control burden on the control unit C.

[0063] Furthermore, in the fan control, the control unit C of this embodiment switches between the first fan F1 and the second fan F2 as the fan to be controlled. This reduces the control burden on the control unit C and enables a stable supply of conditioned air to the conditioned space 50.

[0064] Furthermore, after executing the fan control, the control unit C of this embodiment executes air blowing control to individually control the first fan F1 and the second fan F2 based on new input information received by the input receiving unit 21. According to this configuration, even in the device 1 where the fan control is executed by the control unit C and the device 1 is driven in either the first drive mode or the second drive mode, the first fan F1 and the second fan F2 are individually controlled to blow air in accordance with the user's request during drive, thereby making it possible to stably supply conditioned air adjusted to an appropriate air volume to the conditioned space 50.

[0065] In addition, the device 1 of this embodiment has a first heat exchanger E1 and a second heat exchanger E2 arranged vertically inside the housing 2. This allows the specific air to be heat exchanged with the refrigerant in each of the heat exchangers E1 and E2 while suppressing unnecessary thermal influence between the heat exchangers E1 and E2. Therefore, the device 1 can stably generate conditioned air based on either the first drive mode or the second drive mode and either the cooling mode or the heating mode.

[0066] Furthermore, compared to when the first heat exchanger E1 and the second heat exchanger E2 are arranged side by side in the horizontal direction, the horizontal dimension of the housing 2 can be reduced. As a result, while reducing the arrangement space for the device 1, it is possible to easily arrange the device 1 close to the position where the air to be conditioned is taken out from the space to be conditioned 50 or the position where the conditioned air is supplied to the space to be conditioned 50.

[0067] In addition, the housing 2 of this embodiment has a specific air intake port 2a that takes in specific air inside and a generated air exhaust port 2b that exhausts generated air, and the control unit C is positioned upstream of the first heat exchanger E1 in the air flow direction from the specific air intake port 2a to the generated air exhaust port 2b.

[0068] According to the above configuration, even if condensation occurs on the first heat exchanger E1 and its surroundings when the device 1 is operated in cooling mode, the condensed water can be prevented from adhering to the control unit C. Furthermore, the control unit C can be air-cooled by the specific air taken into the housing 2 through the specific air intake 2a. Therefore, the control unit C can be operated stably.

[0069] As another example, the device 1 includes long duct members 3 and 4 that are connected to at least one of the specific air intake port 2a and the generated air discharge port 2b and extend from the housing 2 to the outside.

[0070] According to the above configuration, by connecting the duct members 3, 4 to the openings, the flow direction of the specific air taken in by the specific air intake port 2a and the flow direction of the generated air discharged from the generated air discharge port 2b can be set so as not to interfere with each other. Therefore, the control unit C can drive the first fan F1 and the second fan F2 under optimal conditions according to the drive mode, and the duct members 3, 4 can be used to stably supply conditioned air to the conditioned space 50 in either drive mode.

[0071] Furthermore, the device 1 of this embodiment is driven in either an air conditioning mode, a heating mode in which the temperature of the conditioned air is higher than the air to be conditioned, or a cooling mode in which the temperature of the conditioned air is lower than the air to be conditioned. As a result, in either the heating mode or the cooling mode, when the device 1 is installed outside the space to be conditioned 50 and conditions the air in the space to be conditioned 50 using the device 1, air can be circulated efficiently between the device 1 and the space to be conditioned 50.

[0072] In this way, the device 1 can be installed and used, for example, outdoors, indoors, or inside a vehicle. When the device 1 is installed in the space 50 to be conditioned, the device 1 can be protected from the outdoors. When the device 1 is installed in the space 50 to be conditioned and operated in heating mode, the heat emitted by the device 1 can warm the air in the space 50 to a certain extent.

[0073] The specific air intake 2a and the generated air exhaust 2b may be arranged on a side surface of the housing 2 (for example, the front surface 20b). In this case, for example, the specific air intake 2a and the generated air exhaust 2b may be arranged side by side at the top of the same side surface. In this case, a first duct member 3 may be connected to the specific air intake 2a, and a second duct member 4 may be connected to the generated air exhaust 2b. In this way, the specific air intake 2a and the generated air exhaust 2b do not necessarily have to be arranged on the top surface 20a of the housing 2. Furthermore, the duct members 3 and 4 are not essential, and may be omitted depending on the installation mode, etc. Below, the modified examples will be described, focusing on the differences from the embodiment.

[0074] (Variation) Similar to the device 1 of the embodiment, the device 1 of this modification includes a temperature sensor S that measures the temperature of the conditioned air circulating inside the housing 2 and a compressor CP that compresses the refrigerant circulating between the first heat exchanger E1 and the second heat exchanger E2 (see FIG. 2). The compressor CP, for example, includes a compression motor that generates a compressive force to compress the refrigerant by being driven to rotate in a predetermined direction. After executing the blower control (S3, S4), the control unit C of this modification executes compressor control to control the rotation speed of the compressor CP (here, as an example, this refers to the rotation speed of the compression motor; also referred to as frequency) based on newly received input information (e.g., information on an instruction to adjust the temperature of the conditioned air) by the input receiving unit 21 and temperature information detected by the temperature sensor S so that the temperature indicated by the temperature information falls within a predetermined temperature range. FIG. 7 is a flowchart of compressor control during normal operation in the device 1 of this modification.

[0075] Specifically, as shown in Fig. 7, during normal driving, the control unit C determines whether input information regarding the temperature adjustment instruction has been received via the input receiving unit 21 or the like (S21). In S21, the control unit C continues the determination of S11 until input information regarding the temperature adjustment instruction is received. If the control unit C determines in S21 that input information regarding the temperature adjustment instruction has been received (S21: Yes), it then determines whether the current drive mode of the device 1 is the first drive mode (S22). If the control unit C determines in S22 that the current drive mode of the device 1 is the first drive mode (S22: Yes), it then executes compressor control to control the rotation speed of the compressor CP based on the first drive mode (S23).

[0076] In this compressor control (S23) in the first drive mode, the control unit C controls the rotation speed of the compressor CP so that the temperature of the conditioned air circulating inside the housing 2, detected by the temperature sensor S, falls within the target temperature range within a predetermined time. For example, if the air conditioning mode of the device 1 is set to cooling mode and the airflow mode of the conditioned air blown from the device 1 is set to "low airflow" mode, the volume of conditioned air blown per unit time to the conditioned space 50 is relatively small. In this case, it takes a certain amount of time for the conditioned air blown from the device 1 to fall within the target temperature range. However, for example, by the control unit C executing compressor control to increase the rotation speed of the compressor CP, the heat exchange efficiency of the air by the heat exchangers E1 and E2 is improved. Therefore, even if the volume of conditioned air is small, the cooling efficiency of the conditioned space 50 based on the first drive mode can be increased. After completing the compressor control (S23), the control unit C terminates the flow.

[0077] On the other hand, if the control unit C determines in S22 that the current drive mode of the device 1 is not the first drive mode (S22: No), the control unit C then executes compressor control based on the second drive mode (S24). Even in this compressor control in the second drive mode (S24), the control unit C can increase the cooling efficiency of the conditioned space 50 based on the second drive mode by executing compressor control such as increasing the rotation speed of the compressor CP. After completing the execution of the compressor control (S24), the control unit C ends the flow.

[0078] As described above, according to this modification, even when the volume of conditioned air blown from the device 1 into the conditioned space 50 is relatively small, the heat exchange efficiency of the air by the first heat exchanger E1 and the second heat exchanger E2 is adjusted, for example, by the control unit C executing compressor control to change the rotation speed of the compressor CP. As a result, conditioned air with a sufficiently adjusted temperature can be supplied to the conditioned space 50 in either the first drive mode or the second drive mode. Furthermore, for example, when the air conditioning mode of the device 1 is the cooling mode, the control unit C executes compressor control to circulate low-temperature conditioned air within the housing 2. This also has the effect of efficiently cooling the heat exchangers E1 and E2 within the housing 2 for dehumidification. Note that in S22, the control unit C may determine whether the drive mode of the device 1 is the second drive mode and reflect the determination result in the compressor control (S23, S24).

[0079] (Addendum) The above description of the embodiment and modifications discloses the following techniques. [Technology 1] a first heat exchanger; a second heat exchanger disposed separately from the first heat exchanger; a first fan that sends air to the first heat exchanger; a second fan that sends air to the second heat exchanger; a control unit that controls the first fan and the second fan; a housing that integrally houses the first heat exchanger, the second heat exchanger, the first fan, the second fan, and the control unit; an input receiving unit that receives input information from an external device, The control unit, based on the input information received by the input receiving unit, a first driving mode in which the first blower blows the air to be conditioned toward the first heat exchanger, causing the first heat exchanger to exchange heat between the air to be conditioned and a refrigerant, thereby generating conditioned air from the air to be conditioned, and the second blower blows outside air toward the second heat exchanger, causing the second heat exchanger to exchange heat between the refrigerant that has exchanged heat with the air to be conditioned by the first heat exchanger and the outside air; an integrated air conditioning apparatus that performs blower control to individually control the first blower and the second blower so as to switch between a first drive mode and a second drive mode in which the second blower blows the air to be conditioned toward the second heat exchanger, causing the second heat exchanger to exchange heat with a refrigerant and generate the conditioned air from the air to be conditioned, and a second drive mode in which the first blower blows the outside air toward the first heat exchanger, causing the first heat exchanger to exchange heat with the refrigerant that has exchanged heat with the air to be conditioned by the second heat exchanger.

[0080] According to the above configuration, the control unit executes blower control, thereby switching the drive mode of the device between a first drive mode and a second drive mode, and switching the heat exchanger that exchanges heat between the air to be conditioned and the outside air between the first heat exchanger and the second heat exchanger.

[0081] For this reason, it is possible to assign each heat exchanger to correspond to the mode in which the device is installed and used inside the space to be conditioned, and the mode in which the device is installed and used outside the space to be conditioned, and it is possible to stably supply the air to be conditioned to the space to be conditioned. Therefore, it is possible to obtain an all-in-one air conditioning unit that can be used well by switching the drive mode between the mode in which the device is installed and used inside the space to be conditioned where the air to be conditioned exists, and the mode in which the device is installed and used outside the space to be conditioned, such as outdoors.

[0082] [Technology 2] In the fan control, the control unit controls the first fan and the second fan so that their rotation speeds are different from each other.

[0083] With this configuration, the first fan and the second fan can be driven independently at optimal rotation speeds according to the drive mode of the device, thereby reducing the control burden on the control unit and enabling a stable supply of conditioned air to the space to be conditioned.

[0084] [Technology 3] In the fan control, the control unit switches the fan to be controlled between the first fan and the second fan.

[0085] According to the above configuration, by switching and selecting the fan to be controlled, it is possible to reduce the control burden on the control unit and to provide a stable supply of conditioned air to the space to be conditioned.

[0086] [Technology 4] The integrated air conditioning device described in any one of techniques 1 to 3, wherein after executing the fan control, the control unit executes fan control to individually control the first fan and the second fan based on the input information newly received by the input receiving unit.

[0087] According to the above configuration, even in a device in which blower control is performed by a control unit and the device is driven in either the first drive mode or the second drive mode, the first blower and the second blower are individually controlled to blow air according to the user's request during operation, thereby enabling a stable supply of conditioned air adjusted to an appropriate air volume to the space to be conditioned.

[0088] [Technology 5] a temperature sensor for measuring the temperature of the conditioned air circulating inside the housing; a compressor that compresses a refrigerant circulating between the first heat exchanger and the second heat exchanger, The integrated air conditioning device described in any one of techniques 1 to 4, wherein after executing the blower control, the control unit executes compressor control to control the rotation speed of the compressor based on the input information newly received by the input receiving unit and the temperature information detected by the temperature sensor so that the temperature indicated by the temperature information falls within a predetermined temperature range.

[0089] According to the above configuration, even when the volume of conditioned air blown from the device into the space to be conditioned is relatively small, the heat exchange efficiency of the air by the first heat exchanger and the second heat exchanger can be adjusted, for example, by the control unit executing compressor control to change the rotation speed of the compressor. As a result, conditioned air with a sufficiently adjusted temperature can be supplied to the space to be conditioned, in either the first drive mode or the second drive mode. Furthermore, for example, when the air conditioning mode of the device is cooling mode, the control unit can execute compressor control to circulate low-temperature conditioned air within the housing. This also has the effect of efficiently cooling the heat exchanger within the housing for dehumidification.

[0090] [Technology 6] The all-in-one air conditioner according to any one of Techniques 1 to 5, wherein the first heat exchanger and the second heat exchanger are arranged side by side in the vertical direction inside the housing.

[0091] According to the above configuration, the first heat exchanger and the second heat exchanger are arranged vertically, so that each heat exchanger can exchange heat with a specific refrigerant while suppressing unnecessary thermal influence between the heat exchangers. Therefore, the device can stably generate conditioned air based on either the first drive mode or the second drive mode and either the cooling mode or the heating mode.

[0092] Furthermore, the horizontal dimension of the housing can be reduced compared to when the first heat exchanger and the second heat exchanger are arranged side by side in the horizontal direction. As a result, the arrangement space for the device can be reduced, and the device can be easily arranged close to the position where the conditioned air is taken out from the space to be conditioned or the position where the conditioned air is supplied to the space to be conditioned.

[0093] [Technology 7] The housing has a specific air intake port that takes in specific air, which is either the air to be conditioned or the outside air, and a generated air outlet that discharges generated air generated by causing the first heat exchanger to exchange heat with a refrigerant, The control unit is arranged at a position upstream of the first heat exchanger in the air flow direction from the specific air intake port toward the generated air outlet.

[0094] According to the above configuration, the control unit is located upstream of the first heat exchanger in the direction of air flow from the specific air intake to the generated air outlet. Therefore, even if condensation occurs on the first heat exchanger and its surroundings when the device is operated in cooling mode, the condensed water can be prevented from adhering to the control unit. Furthermore, the control unit can be air-cooled by the specific air drawn into the housing through the specific air intake. Therefore, the control unit can be operated stably.

[0095] [Technology 8] The integrated air conditioning device described in Technology 7 is provided with a long duct member that is connected to an opening that is at least one of the specific air intake port and the generated air discharge port and extends from the housing to the outside.

[0096] According to the above configuration, by connecting a duct member to the opening, the flow direction of the specific air taken in through the specific air intake port can be separated from the flow direction of the generated air discharged from the generated air exhaust port. Therefore, the first and second fans can be driven under conditions that correspond to whether the device is installed and used inside the conditioned space where the air to be conditioned exists, or whether the device is installed and used outside the conditioned space, such as outdoors, and in either drive mode, the duct member can be used to provide a stable supply of conditioned air to the conditioned space.

[0097] [Technology 9] a heating mode in which the temperature of the conditioned air is higher than the temperature of the air to be conditioned; and a cooling mode in which the temperature of the conditioned air is lower than the temperature of the air to be conditioned.

[0098] According to the above configuration, in either the heating mode or the cooling mode, when an integrated air conditioning device is installed outside the space to be conditioned and the device conditions the air in the space to be conditioned, air can be efficiently circulated between the device and the space to be conditioned.

[0099] The present disclosure is not limited to the above-described embodiments and modifications, and modifications, additions, or deletions to the configuration may be made without departing from the spirit of the present disclosure. The power source for the integrated air conditioning device of the present disclosure is not limited to a power supply circuit permanently installed in a building or the like (in the example of FIG. 3, an electrical circuit connected to an indoor outlet), but may also be a portable power source (external power source) such as a battery or a portable generator.
