As shown in FIG. 9, the brackets 36 of the two guide pipes 32 are common, and the vertical portion 34 at the end is formed on the beam 3 of the housing unit 1 which becomes the ceiling beam of the building as shown in FIG. Hole
3B, the bracket 36 is applied to the beam 3, the screw 38 is inserted into the hole 37 provided in the bracket 36, and the bracket 36 is coupled to the beam 3 by the screw 38, so that the guide pipe 32 is fixed to the housing unit 1. Attached to. The end of the sheath 8 of the guide tube 7 is inserted into the horizontal portion 33, and the split groove 39 of the horizontal portion 33 is inserted.
Is narrowed by tightening the screw 40, the sheath tube 8 is connected to the guide tube 32. A heat insulating pipe 41 that guides the refrigerant pipe 11 to the indoor unit 4 in a heat insulating state is connected to the vertical portion 34.

The guide pipe 7, the connecting pipe 24, the elastic pipe 31, and the guide pipe described above.
The reference numeral 32 is preliminarily attached to each housing unit 1 through which the refrigerant pipe 1 is piped when the housing unit 1 is produced in a factory, and the floor plan of the building in which the arrangement positions of the indoor unit 4 and the outdoor unit 5 are determined. The guide pipe 7, the connecting pipe 24, the elastic pipe 31, and the guide pipe 32 are attached to predetermined positions of the housing unit 1 according to the piping position of the refrigerant pipe 1 determined in the figure. As shown in FIG. 4, the guide tube 7 is fixed by a fixture 42 and is in an immovable state.

The housing units 1 produced as units at the factory are transported to the construction site, and these housing units 1 are moved forward, backward, left, right,
The building is built by combining the top and bottom. When the housing units 1 in which the refrigerant pipes 11 are piped are combined with each other, the elastic pipes 31 provided so as to project from the housing unit 1 are connected to each other.

The guide pipes 7 can be connected to each other via the connecting pipe 24 in a state of being blocked from the outside by 31 and even if an error occurs in the longitudinal direction of the connecting pipe 24 at the arrangement position of the housing unit 1, the elastic pipe 31 expands and contracts. It is possible to connect while absorbing this error.

After assembling each housing unit 1, guide the refrigerant pipe 11 from the insertion hole provided in one of the guide pipes 7, specifically, the end of the guide pipe 7 on each indoor unit 4 side or outdoor unit 5 side. It is inserted into the tube 7 by pushing it. The refrigerant pipe 11 is inserted into the respective guide pipes 7 through the connecting pipe 24 and the elastic pipe 31, and is further inserted into the guide pipe 32, whereby the refrigerant pipe 11 is bent downward from the horizontal direction of the guide pipe 32 in the vertical direction. Guided to the indoor unit 4 through the section 35 from the ceiling,
After the above-described work of inserting the refrigerant pipe 11, the both ends of the refrigerant pipe 11 are connected to the indoor unit 4 and the outdoor unit 5.

As described above, the guide tube 7 and the like are attached to the housing unit 1 in advance when the housing unit 1 is produced in the factory,
Since the guide pipes 7 are connected to each other when building the building by combining the housing units 1 at the construction site, it is only necessary to insert the refrigerant pipe 11 into the guide pipe 7 at the construction site, that is, the industrialized house. Since the rate of factory implementation in Japan will increase and the work share at the construction site will decrease,
It is possible to improve work efficiency and reduce costs.

Even if there is a gap 43 between the housing units 1 through which the refrigerant pipes 11 are piped as shown in FIG. 8, the connecting pipes 24 are elastic pipes.
Because it is connected in the state of being blocked from the outside by 31,
The refrigerant pipe 11 inserted through this portion is not exposed to the outside, and therefore the safety of the refrigerant pipe 11 is ensured, and the heat insulation of the refrigerant pipe 11 is ensured by the elastic pipe 31 made of a heat insulating material.

Further, when the refrigerant pipe 11 is inserted into the guide pipe 32 and guided vertically downward from the ceiling ceiling, since the guide pipe 32 is provided with the curved portion 35 having a large radius of curvature, the refrigerant pipe 11 is bent. Without changing the direction, the direction is surely changed to the vertical downward direction and advances toward the indoor unit 4. Further, since the guide pipe 32 is connected to the ceiling beam 3 by the bracket 36, the refrigerant pipe 11 is guided toward the indoor unit 4 without opening a hole for inserting the refrigerant pipe in the ceiling boat attached to the ceiling beam 3. The advantage is that it does not damage the ceiling board.

Further, since the liquid pipe 13 of the refrigerant pipe 11 has a structure in which the electric cable 20 is integrally attached, the liquid pipe 13
The electric cable by inserting the cable into the guide tube 7 etc.
20 can be wired to the building, and work efficiency is improved by sharing the work. Further, even if the liquid pipe 13 is provided with the electric cable 20 as described above, the thicknesses of the steam pipe 12 and the liquid pipe 13 do not change so much as described above. The same guide tube 7 etc. can be used for 13. Further, since the shielding tapes 16 and 21 made of a laminated material of aluminum and polyester, etc. are wound around the outermost circumferences of the steam pipe 12 and the liquid pipe 13, respectively, the guide pipes 7 of the steam pipe 12 and the liquid pipe 13 are wound. The slip during insertion can be improved, and insertion work can be facilitated.

Although a plurality of indoor units are connected to one outdoor unit in the above embodiment, the present invention is also applicable to the case where one indoor unit is connected to one outdoor unit, and the refrigerant Instead of inserting the vapor pipe and the liquid pipe of the pipe into separate guide pipes,
It can also be applied to the case where it is inserted into one common guide tube.

[Effect of device]
