[0017] Hereinafter, an embodiment of an air conditioning system will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic diagram illustrating a packaging material management system according to one embodiment of the present disclosure. After being manufactured at a manufacturing factory 1, an air conditioner 10 is packed in packaging materials 21 and 22 and delivered to an installation site 2 such as a building or a store via a predetermined route R1. In the example shown in FIG. 1 , the air conditioner 10 packed in packaging materials 21 and 22 is delivered from the manufacturing factory 1 as the delivery source and temporarily stored in a warehouse 3 of the manufacturer, sales company, etc. The stored air conditioner 10 is delivered to the installation site 2 via a sales store 4. At the installation site 2, the air conditioner 10 is unpacked and installed.

[0018] The flow of the air conditioner 10 delivered from the manufacturing factory 1 to the installation site 2 via relay points such as the warehouse 3 and the retail store 4 as described above is called the delivery route R1. In this embodiment, in addition to the delivery route R1, a return route R2 for the packaging materials 21, 22 that packed the air conditioner 10 is also set. This return route R2 is a route for delivering the packaging materials 21, 22 from the installation site 2 to the manufacturing factory 1 via relay points such as the return base 5. The return base 5 is a location where the packaging materials 21, 22 are temporarily collected and inspected, cleaned, repaired, etc., before being returned to the manufacturing factory 1. The delivery route R1 and return route R2 described above are merely examples, and any of the relay points 3 to 5 may be omitted, or other relay points may be added.

[0019] (Packaging structure) FIG. 2A is a perspective view of an air conditioner packed in packing material. The air conditioner 10 is a separate type that includes, for example, an outdoor unit that is installed outdoors and an indoor unit that is installed indoors. The outdoor unit and the indoor unit are formed, for example, in a rectangular parallelepiped shape, and are each packed in packaging material 20.

[0020] The packaging material 20 includes a first packaging material 21 and a second packaging material 22. The first packaging material 21 packs the upper part of the air conditioner 10. The second packaging material 22 packs the lower part of the air conditioner 10. The first packaging material 21 and the second packaging material 22 are formed in a substantially rectangular parallelepiped shape with a quadrilateral (rectangular) upper surface that is larger than the upper surface of the air conditioner 10. The first packaging material 21 and the second packaging material 22 have heights H1, H2 that are smaller than the height of the air conditioner 10.

[0021] A recess 21a into which the upper part of the air conditioner 10 is fitted is formed on the lower surface of the first packaging material 21. A recess 22a into which the lower part of the air conditioner 10 is fitted is formed on the upper surface of the second packaging material 22. A protrusion 22b is formed around the recess 22a of the second packaging material 22 along the outer periphery of the air conditioner 10. Around the recess 21a of the first packaging material 21, at a position corresponding to the protrusion 22b, another recess 21b is formed along the outer periphery of the air conditioner 10. The first packaging material 21 and the second packaging material 22 that pack the air conditioner 10 are fixed to the air conditioner 10 by a tie band, an outer box, or the like (not shown).

[0022] The first packaging material 21 and the second packaging material 22 are configured to be reusable. The first packaging material 21 and the second packaging material 22 are formed from, for example, polystyrene foam, polyethylene foam, etc. The first packaging material 21 and the second packaging material 22 may also be formed from a hard synthetic resin material or wood, and there are no particular limitations on the material as long as they are reusable.

[0023] FIG. 2B is a perspective view of the integrated first and second packaging materials. The first packaging material 21 and the second packaging material 22 are integrated by being stacked one on top of the other in the vertical direction. Specifically, when the first packaging material 21 and the second packaging material 22 are stacked one on top of the other, the recessed portion 21b formed in the first packaging material 21 is fitted with the protruding portion 22b formed in the second packaging material 22, thereby integrating the first packaging material 21 and the second packaging material 22. In other words, the first packaging material 21 has a fitting portion (recessed portion) 21b, and the second packaging material 22 has a fitted portion (protruding portion) 22b that fits into the fitting portion 21b, and the first packaging material 21 and the second packaging material 22 are integrated by fitting the fitting portion 21b into the fitted portion 22b. The vertical length (height) H3 of the integrated first packaging material 21 and second packaging material 22 is smaller than the sum of the vertical length (height) H1 of the first packaging material 21 and the vertical length (height including the convex portion 22b) H2 of the second packaging material 22.

[0024] In addition, in this embodiment, the first packaging material 21 may have a convex portion formed as the fitting portion 21b, and the second packaging material 22 may have a concave portion formed as the fitted portion 22b, and the first packaging material 21 and the second packaging material 22 may be integrated by fitting the convex portion as the fitting portion 21b and the concave portion as the fitted portion 22b together.

[0025] (Management system details) 1, the management system 30 of this embodiment is a system that manages packaging materials 21, 22 from the manufacturing factory 1 through the delivery route R1 and return route R2 until they are returned to the manufacturing factory 1. The management system 30 includes a management device 31. The management device 31 of this embodiment is installed in the manufacturing factory 1.

[0026] FIG. 3 is a block diagram of the management device and the transmission device. The management device 31 is, for example, a personal computer, and has a control unit 32, a memory unit 33, a communication unit 34, and a display unit 35. The control unit 32 is configured using a CPU. The memory unit 33 is configured using RAM, ROM, a hard disk, an SSD, etc. The communication unit 34 is configured using a communication interface. The control unit 32 performs a predetermined function by executing a program stored in the memory unit 33. The communication unit 34 is connected to a communication unit 44 of the transmission device 41 (described later) via a network 50 so as to be able to communicate with the communication unit 44 via the network 50. The network 50 is the Internet, an intranet, etc. The display unit 35 is configured using a monitor that displays the management status and other conditions.

[0027] The management device 31 manages the air conditioner 10 and the packaging materials 21 and 22. Specifically, the management device 31 manages air conditioner information, which is identification information for identifying the air conditioner 10, and packaging material information, which is identification information for identifying the packaging materials 21 and 22. The storage unit 33 of the management device 31 stores the air conditioner information of the air conditioner 10 to be delivered and the packaging material information of the packaging materials 21 and 22 in which the air conditioner 10 is packed, in an associated state. Specifically, as shown in FIG. 2A , the air conditioner 10 is assigned an identifier 10A in which identification information such as the model and product number is recorded. Similarly, the packaging materials 21 and 22 are assigned identifiers 21A and 22A in which identification information is recorded. Barcodes, IC tags (RFID tags), etc. can be used as the identifiers 10A, 21A, and 22A.

[0028] The management system 30 further includes a reading device 36. The reading device 36 reads the identifiers 10A, 21A, and 22A assigned to the air conditioner 10 and the packaging materials 21 and 22. The reading device 36 transmits the read air conditioner information and packaging material information to the management device 31. The management device 31 stores the received air conditioner information and packaging material information in a corresponding state in the memory unit 33. The management device 31 also reads the identifiers 21A and 22A of the packaging materials 21 and 22 that have returned to the manufacturing plant 1 via the return route R2 with the reading device 36 to acquire the packaging material information and manage it as return information. The memory unit 33 of the management device 31 may store at least one additional piece of information, such as the delivery date of the air conditioner 10, the delivery date, and the scheduled return date of the packaging materials 21 and 22, in addition to the air conditioner information, packaging material information, and return information.

[0029] The management device 31 compares the packaging material information of the returned packaging materials 21, 22 with the packaging material information stored in the memory unit 33. Packaging materials 21, 22 that have been confirmed to have been returned are processed as having been collected, and management is terminated. The management device 31 can check whether all packaging materials 21, 22 under its management have been collected, and can take measures to increase the collection rate, such as checking the status of packaging materials 21, 22 that have not been collected with the installation company or the return base company, or urging them to return them.

[0030] The management device 31 outputs a management table 40, such as the one shown in FIG. 4, to the display unit 35. This management table 40 indicates that two sets of packaging materials, such as management Nos. 1 and 2 and 3 and 4, are used to pack one air conditioner. The management device 31 has a function to notify the operator if the packaging materials 21 and 22 have not been returned by a preset return date. For example, in the management table 40 shown in FIG. 4, the column for the packaging material that has not been returned by the return date (e.g., management No. 6) displays the background and text in a conspicuous color (e.g., red or yellow) to make it visually clear, and notifies the operator. Similarly, if only one of the first packaging material 21 and the second packaging material 22 has been returned and the other has not, the background and text are displayed in a conspicuous color to clearly identify the corresponding packaging material, and notifies the operator. This allows the operator to easily determine which packaging materials have not been returned.

[0031] (Tracking of packaging materials) The management system 30 of this embodiment promotes the collection of the packaging materials 21, 22 by tracking the packaging materials 21, 22 along the delivery route R1 and return route R2. Specifically, the warehouse 3, the dealer 4, the installation site 2, and the return base 5 are equipped with a reading device 36 that reads the identifiers 10A, 21A, and 22A assigned to the air conditioners 10 and the packaging materials 21 and 22, respectively, and a transmitting device 41 that acquires the air conditioner information and packaging material information recorded in the read identifiers and transmits this information to the outside.

[0032] The transmitting device 41 is configured, for example, by a personal computer, and has a control unit 42, a memory unit 43, and a communication unit 44. The control unit 42 is configured using a CPU. The memory unit 43 is configured using RAM, ROM, a hard disk, an SSD, etc. The communication unit 44 is made up of a communication interface. The control unit 42 performs predetermined functions by executing programs stored in the memory unit 43. The communication unit 44 is connected to the communication unit of the management device 31 via a network 50 so as to be able to communicate with the communication unit of the management device 31. The transmitting device 41 may be permanently installed in various locations, or may be a portable (handheld) terminal such as a laptop computer, tablet, or smartphone. The transmitting device 41 may also be a smartphone or the like having functions such as a barcode reader.

[0033] When the air conditioner 10 and packaging materials 21, 22 are delivered from the manufacturing factory 1, the identification information recorded in the identifiers 10A, 21A, 22A is read by a reading device 36 installed at each of the relay points 3-5 and the installation site 2. The read identification information is sent from the transmitting device 41 to the management device 31 via the network 50. This enables the management device 31 to track the air conditioner 10 and packaging materials 21, 22 and confirm their current locations. Therefore, it becomes possible to confirm the current locations of packaging materials 21, 22 whose collection has not been confirmed, and to promote collection.

[0034] The flow of processing in the management system 30 as described above will now be briefly explained with reference to the flowchart of FIG. In the management system 30, the air conditioner information and packaging material information are read by the reading device 36 in the manufacturing factory 1, and this information is stored in the storage unit 33 of the management device 31 (step S1).

[0035] When the packaged air conditioner 10 is delivered, the management system 30 uses the reading device 36 to read the air conditioner information and packaging material information at relay points 3 and 4 on the way to the delivery destination 2, and transmits this information from the transmitting device 41 to the management device 31. The management device 31 stores the received air conditioner information and packaging material information together with information about the sender (information about the relay points) in the memory unit 33 (step S2).

[0036] When the air conditioner 10 arrives at the delivery destination 2, the management system 30 reads the air conditioner information and packaging material information using the reading device 36, and transmits this information from the transmitting device 41 to the management device 31. The management device 31 stores the received air conditioner information and packaging material information together with the information of the sender (delivery destination information) in the memory unit 33 (step S3).

[0037] When the packaging materials 21, 22 returned from the delivery destination arrive at the return location 5, the management system 30 reads the packaging material information using the reading device 36 and transmits this information from the transmitting device 41 to the management device 31. The management device 31 stores the received packaging material information together with the information of the sender (information of the relay point) in the memory unit 33 (step S4).

[0038] When the packaging materials 21, 22 arrive at the manufacturing factory 1 from the return base 5, the management device 31 acquires the packaging material information read by the reading device 36. The management device 31 compares the acquired packaging material information with the packaging material information stored in the memory unit 33 before shipping, and confirms that the packaging materials have been returned (step S5).

[0039] [Other embodiments] In the above embodiment, the identifiers 21A and 22A are provided on both the first packaging material 21 and the second packaging material 22, but the identifiers 21A and 22A may be provided on only one of them. Since the first packaging material 21 and the second packaging material 22 are returned in an integrated state, the identifier of one of the packaging materials is read by the reading device 36 and transmitted to the management device 31, whereby the management device 31 can recognize that both the first packaging material 21 and the second packaging material 22 have been returned.

[0040] The management device 31 may be installed in a location other than the manufacturing factory 1, such as the manufacturer's warehouse 3. The management device 31 may also be installed outside the locations shown in Fig. 1, such as the manufacturer's management center (control center). In this case, a reading device 36 and a transmitting device 41 are installed in the manufacturing factory 1, just like the other relay points 3 to 5, and the read air conditioner information and packaging material information are transmitted to the management device 31 via the network 50.

[0041] Instead of the identifiers 10A, 21A, 22A that record the identification information of the air conditioner 10 and the packaging materials 21, 22, a GPS (Global Positioning System) receiver and a location information transmitter may be provided in the packaging materials 21, 22. In this case, the GPS receiver receives satellite signals from the GPS to determine its own location, and the transmitter can transmit this location information to the management device 31 via the network 50.

[0042] [Effects of the embodiment] The management system 30 of the above embodiment has a management device 31 that stores air conditioner information for identifying the air conditioner 10 and packaging material information for identifying the first packaging material 21 and the second packaging material 22 in correspondence with each other, and that acquires the packaging material information of the packaging materials 21 and 22 returned from the delivery destination after the air conditioner 10 is delivered.

[0043] Air conditioners 10 are often packaged in multiple packaging materials 21, 22, and when they are to be reused, it is necessary to collect all of the packaging materials 21, 22 together. In the management system 30, the management device 31 stores the identification information of the air conditioner 10 in association with the identification information of the first packaging material 21 and the second packaging material 22, and after the air conditioner 10 is delivered, the management device 31 acquires the packaging material information of the returned packaging materials 21, 22. This makes it possible to know that the multiple packaging materials 21, 22 have been collected together.

[0044] In the above embodiment, at least one of the first packaging material 21 and the second packaging material 22 has an identifier 21A, 22A that includes packaging material information, and the management system 30 further has a reading device 36 that reads the packaging material information from the identifier 21A, 22A. This makes it possible to read the packaging material information from the identifiers assigned to the first and second packaging materials 22, for example, at the delivery origin 1 of the packaging materials 21, 22 or at delivery relay points 3 to 5, and manage the read packaging material information in the management device 31.

[0045] In the above embodiment, both the first packaging material 21 and the second packaging material 22 have the identifiers 21A and 22A, respectively. This allows the reading device 36 to read the packaging material information of the first packaging material 21 and the second packaging material 22 individually, and the information can be managed by the management device 31. Because both the first packaging material 21 and the second packaging material 22 have the identifiers 21A and 22A, respectively, it can be accurately determined whether both the first packaging material 21 and the second packaging material 22 have been returned.

[0046] In the above embodiment, the first packaging material 21 has a recess as the fitting portion 21b, and the second packaging material 22 has a protrusion as the fitted portion 22b that fits into the fitting portion 21b when the first packaging material 21 and the second packaging material 22 are stacked in the vertical direction (predetermined direction). In this case, one of the first packaging material 21 and the second packaging material 22 may have an identifier 21A, 22A including packaging material information. As a result, the first packaging material 21 and the second packaging material 22 can be integrated by fitting the fitting portion 21b of the first packaging material 21 with the fitted portion 22b of the second packaging material 22. By reading the identifier 21A, 22A provided on one of the integrated first and second packaging materials 21, 22 with the reading device 36, the management device 31 can manage both the returned first and second packaging materials 21, 22. The fitting portion 21b may be a convex portion, and the fitted portion 22b may be a concave portion that fits into the convex portion.

[0047] In the above embodiment, the length H3 in the vertical direction of the first packaging material 21 and the second packaging material 22 when the fitted portion 22b and the fitting portion 21b are fitted together is smaller than the sum of the length H1 in the vertical direction of the first packaging material 21 and the length H2 in the vertical direction of the second packaging material 22. Therefore, by integrating the first and second packaging materials 21 and 22, the length of the packaging materials 21 and 22 in the overlapping direction can be reduced, and transportation efficiency can be improved.

[0048] In the above embodiment, the management device 31 identifies and notifies the first packaging material 21 and the second packaging material 22 that have not been returned. Therefore, it is possible to easily know that the first packaging material 21 and the second packaging material 22 have not been returned as a set.

[0049] It should be noted that the present disclosure is not limited to the above examples, but is defined by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. [Explanation of symbols]
