By the way, in the drain pipe, since cold water flows in the pipe, water droplets are easily generated on the outer circumference. Therefore, if used as it is, the water droplets tend to cause dew condensation on the outer wall, which also affects the useful life of the building. Therefore, a heat insulating material is wrapped around the drain pipe to prevent the generation of water droplets and dew condensation. Therefore, the drain pipe has a large outer diameter.

Conventionally, since such a drain pipe is arranged in the gap between the outer wall and the inner wall of the building unit, the space occupied by the drain pipe becomes large, and the position of the inner wall recedes toward the indoor side. As a result, the space in the room is narrowed, so that the indoor space cannot be effectively used, and the degree of freedom in floor plan design is limited. In addition, since the drain pipe is installed in the gap between the outer wall and the inner wall of the building unit, the work is done in a narrow space in the room or the equipment in the room is an obstacle, making the work difficult and making the piping work difficult. There was also the problem of being there.

It is an object of the present invention to effectively use an indoor space, improve the degree of freedom in floor plan design, and facilitate piping work, and a drain pipe piping structure for an air conditioner in a unit type building and It is to provide the piping method.
