Abstract

PROBLEM TO BE SOLVED: To recover replacing gas conveniently after air in an indoor heat exchanger is replaced temporarily by the replacing gas by coupling a connector with a replacing gas recovery container and opening the replacing gas recovery container with the cutter of the connector. SOLUTION: When a connector 30 is fixed to a refrigerant charge port 8b, a valve core in the refrigerant charge port 8b is pushed by a valve stem in the connector 30 and the refrigerant charge port 8b is brought into open state. When a replacing gas recovery container 20 is fixed subsequently to the connector 30, opening of the replacing gas recovery container 20 is unsealed with the cutter of the connector 30. Carbon dioxide gas in the replacing gas recovery container 20 is thereby introduced from the refrigerant charge port 8b into connection piping 10 and an indoor unit B through the connector 30 and then introduced to connection piping 9. Air in the connection piping 9, 10 and the indoor unit B is discharged, along with the introduced carbon dioxide gas, into the atmosphere from the loosened part of the flare part of a liquid side two-way valve 7.

Oxygen and water promote the deterioration of refrigeration oil and iron inside the refrigeration cycle and must be removed. Among the methods described in the prior art, the method of evacuating with a vacuum pump is common, but a power supply must be available to operate the vacuum pump at the construction site, and it is difficult to use it on a roof etc. It could not be called a simple method. Further, in the method of replacing air with a refrigerant, it is unavoidable to release Freon, which is a refrigerant, to the atmosphere, which is not preferable from the viewpoint of global environment, such as global warming. Further, as for a method of recovering the replacement gas after once replacing the air in the indoor heat exchanger or the connection pipe with the replacement gas, no simple device for recovering the replacement gas has been proposed.

When carbon dioxide is sealed as a replacement gas, zeolite, an epoxy compound, calcium hydroxide, or the like can be used as a substance that absorbs the replacement gas. Among them, zeolite is more preferable because of its high absorption rate. The zeolite having a pore diameter of 1.0 nm is optimal because it has a high carbon dioxide absorption rate. Although the shape of the zeolite is not particularly specified, it is preferable that the zeolite be spherical because it is difficult to be crushed.

る。As described above, according to the present invention, the refrigerant charging port can be opened only by connecting the connecting device to the refrigerant charging port, and the replacement gas filling container is connected to the connecting device. The replacement gas-filled container can be opened simply by doing so. Therefore, by connecting the connection device to the refrigerant charge port and connecting the replacement gas filling container to the connection device, the replacement gas in the replacement gas filling container can flow from the refrigerant charge port,
The operation of flowing the replacement gas in the replacement gas filling container into the air conditioner can be performed only by connecting this connection device. As described above, it is not necessary to operate the vacuum pump as in the related art, and when using the replacement gas, a single-use type without a valve can be used without using a large cylinder having a valve. The replacement gas-filled container can be used, and the workability of the air conditioner can be improved. Further, according to the present invention, the refrigerant charge port can be opened simply by connecting the connection device to the refrigerant charge port, and the replacement gas recovery container can be opened simply by connecting the replacement gas recovery container to the connection device. The container can be opened. Therefore, by connecting the replacement gas filling container to the connection device and connecting the connection device to the connection refrigerant charge port, the replacement gas can be recovered from the refrigerant charge port into the replacement gas recovery container, The operation of recovering the replacement gas from the air conditioner into the replacement gas recovery container can be performed simply by connecting this connection device. As described above, it is not necessary to operate the vacuum pump as in the related art, and even when using the replacement gas, a single-use type without a valve can be used without using a large container having a valve. The replacement gas recovery container can be used, and the workability of the air conditioner can be improved. Further, according to the present invention, the refrigerant charge port can be opened only by connecting the connection device to the refrigerant charge port, and a replacement gas filling device or a replacement gas recovery container is connected to the connection device. The gas filling device for replacement or the gas recovery container for replacement can be opened only by the above. Therefore, since both the replacement gas filling container and the replacement gas recovery container can be used,
Once the air in the air conditioner is replaced by the replacement gas,
Thereafter, the operation of recovering the replacement gas can be performed only by using the connection device. Further, according to the present invention, the connection between the first connection port and the refrigerant charge port can be performed without mixing atmospheric air. Further, according to the present invention, screwing can be performed without rotating the connection device itself, so that workability at the time of construction is excellent. Further, according to the present invention, a one-time use type filling device having no open / close valve can be provided, and the filling container can be reduced in size.
