[Background Art] When an air conditioner in which an outdoor unit and an indoor unit are separated is installed in a unit house constructed by combining a plurality of housing units pre-produced in a factory at a construction site, both ends are an outdoor unit and an indoor unit. The refrigerant pipe connected to and must be laid across multiple housing units. A conventional technique for piping a refrigerant pipe across a plurality of housing units that form a unit housing in this way is disclosed in Japanese Patent Laid-Open No. 2-282565.

In this conventional technique, a guide pipe formed of a heat insulating material is attached to each housing unit in which a refrigerant pipe is piped by extending it in the direction of the refrigerant pipe, and these housing units are combined to build a unit house. The guide tubes are connected to each other, the refrigerant tube is inserted from one open end of the long guide tube formed by this connection, and this refrigerant tube is inserted and piped toward the other open end of the long guide tube. It is a thing.

Further, conventionally, a wire is inserted from one of the open ends of the long guide tube, and a refrigerant tube is connected to the tip of the wire protruding from the open end on the opposite side of the long guide tube to pull the wire. As a result, the refrigerant pipe has also been inserted and piped into the long guide pipe.

[0005]

According to the above-mentioned conventional refrigerant pipe piping method, since the long guide pipe has a length as long as the refrigerant pipe pipe distance, the refrigerant pipe is connected to the long guide pipe. If you insert the refrigerant pipe directly, the refrigerant pipe will be caught in the middle of the long guide pipe, and it will take time to pass the refrigerant pipe through the entire length of the long guide pipe. If you pull the wire with a long wire and run it through the entire length of the long guide tube, the wire will get caught in the middle of the long guide tube, and it will take time to pass the wire through the entire length of the long guide tube. It was hanging.

Further, in the above-mentioned conventional technique, since a long guide tube is used, there is a problem that the cost for the guide tube becomes high.

It is an object of the present invention to provide a refrigerant pipe piping method for an air conditioner in a unit house, which facilitates work for piping a refrigerant pipe and can improve workability.
