(1) Overall configuration The refrigerant management system 100 is a system that manages the refrigerant used in the refrigerant-using equipment. A refrigerant-using device is a device provided with a vapor-compression refrigeration cycle using a refrigerant. Refrigerant-using equipment is, for example, an air conditioner, an air purifier, a heat pump type hot water supply device, a refrigerating device, or a refrigerating device. The refrigerant used in the refrigerant-using equipment is, for example, R32, R452B, R410A, R454B, an HFO-based mixed refrigerant (for example, a mixed refrigerant of HFO-1123 and R32), CO2 or CF3I (single or a mixed refrigerant thereof). ..

Refrigerant management performed by the refrigerant management system 100 means that the refrigerants circulating in the refrigerant circulation cycle are centrally grasped, or the grasped refrigerant information is provided to each trader. FIG. 1 is a schematic diagram of a refrigerant circulation cycle. The refrigerant circulation cycle mainly consists of a production stage, a distribution stage, an installation stage, a maintenance stage, a recovery stage, a regeneration stage, and a disposal stage. In FIG. 1, the flow of the refrigerant is indicated by an arrow. The refrigerant is distributed in a state of being filled in a dedicated container such as a cylinder or a device using a refrigerant. FIG. 1 shows the flow of the container R1 filled with the refrigerant and the refrigerant-using device R2 filled with the refrigerant.

At the production stage, a new refrigerant is produced by the refrigerant manufacturer. At the distribution stage, the newly produced refrigerant is filled in a dedicated cylinder or the like and shipped. Refrigerant shipping destinations are, for example, a manufacturer of a refrigerant-using device (hereinafter referred to as "equipment manufacturer"), an installer of the refrigerant-using device, and a maintenance company of the refrigerant-using device. The equipment manufacturer, installation company, and maintenance company may be the same company or different companies from each other. The equipment manufacturer fills the refrigerant-using equipment with the refrigerant as necessary at the time of manufacturing or shipping the refrigerant-using equipment.

In the distribution stage, the newly produced refrigerant or the regenerated refrigerant is distributed by the refrigerant distributor. The distributor, for example, purchases a refrigerant produced by a refrigerant manufacturer or a regenerated refrigerant and sells it to at least one of an equipment manufacturer, an installer, and a maintenance company. The distributor may be a distributor of the refrigerant. The distributor may be a distributor that distributes the refrigerant-using equipment filled with the refrigerant.

At the installation stage, the refrigerant-using equipment is installed at a predetermined installation location by the installer. The predetermined installation location is, for example, a property such as a building used or owned by the owner of the equipment using the refrigerant. When installing the refrigerant-using equipment, the installer fills the refrigerant-using equipment and the refrigerant piping with the refrigerant by using a cylinder or the like filled with the refrigerant, if necessary.

In the maintenance stage, the maintenance company manages the installed refrigerant-using equipment. Specifically, the maintenance company performs inspection work or repair work of the equipment using the refrigerant. If necessary, the maintenance contractor uses a cylinder or the like filled with the refrigerant to replace the refrigerant filled in the refrigerant-using equipment or refill the refrigerant-using equipment to replenish the refrigerant. .. The refrigerant replacement work is performed, for example, when a predetermined period has elapsed after the equipment using the refrigerant is installed. The refrigerant refilling operation is performed, for example, when it is discovered at the time of inspection that the amount of the refrigerant filled in the equipment using the refrigerant is insufficient.

At the recovery stage, the refrigerant recovery company recovers the refrigerant-using equipment, or the refrigerant-using equipment installed in the property and the refrigerant filled in the refrigerant piping. The recovery company recovers the refrigerant when repairing, relocating, or disposing of the equipment using the refrigerant.

And so on. The recovery company also takes out the refrigerant from the refrigerant-using equipment and recovers it when replacing the refrigerant filled in the refrigerant-using equipment.

In the regeneration stage, the refrigerant regenerator regenerates the refrigerant recovered by the recovery company. The refrigerant regeneration process is, for example, a process of removing impurities from the recovered refrigerant and a process of reproducing the refrigerant using the recovered refrigerant as a raw material. The regenerator takes a cylinder or the like filled with the refrigerant to be regenerated from the collector and regenerates the refrigerant. The regenerated refrigerant is filled in a dedicated cylinder or the like.

At the disposal stage, a part of the refrigerant recovered by the collection company is discarded by the disposal company. Disposal of the refrigerant means, for example, the work of chemically destroying the refrigerant to convert it into a substance that does not adversely affect the human body and the environment, and the work of storing the refrigerant so that it is not used. The abandoner takes over the equipment and cylinders that use the refrigerant filled with the refrigerant to be abolished from the collector and disposes of the refrigerant.

In the following, the term "contractor" shall mean an equipment manufacturer, a refrigerant manufacturer, an installation company, a maintenance company, a collection company, a remanufacturing company, and a distributor, unless otherwise specified. At least some of these vendors may be the same vendor. For example, the equipment manufacturer, the installation company, the maintenance company, and the collection company may be the same company, and the remanufacturing company and the distributor may be the same company. In the present embodiment, it is assumed that the installation contractor, the maintenance contractor, and the collection contractor are the same contractor.

When it is determined in step S14 that the input data including the capacity information is not input and the capacity information is not registered in the device information database DB1, the refrigerant filling amount of the refrigerant-using device 30 is input in step S16. It is determined whether or not it has been done. If it is determined that the input is made in step S16, it is determined in step S17 whether or not the input value of the prefilled amount of the refrigerant is appropriate. For example, it is determined whether or not the amount of the refrigerant already filled is within a predetermined range. The predetermined range may be, for example, between 18 kg and 26 kg with a margin in the value predicted based on the above ability information. If it is determined in step S17 that the input value is appropriate, the input value is acquired as the amount of the refrigerant already filled in step S18.
If it is determined in step S16 that the input value is not input, or if it is determined in step S17 that the input value is not valid, the default value of the refrigerant charged amount is acquired in step S19. In step S20, the storage unit 22 of the management server 20 stores the pre-filled amount of the refrigerant acquired in steps S13, S15, S18, and S19 as the pre-filled amount of the refrigerant of the refrigerant-using device 30.
