Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a piping structure of an air conditioner suitable for office buildings and the like.

(Prior Art) The present applicant has already applied for an air conditioner shown in FIG.

In FIG. 3, 100 is a room, 7 is a floor, 2 is a ceiling, 8 is a pillar, 6 is an outer wall separating the room from the room, and 11 is a window.

The indoor unit 1 is located in the upper space of the ceiling 2, that is, behind the ceiling.
Is installed on the floor 7 along the outer wall 6 under the window 11 along with the outdoor unit 3, the integrated air conditioning unit 4, and the ventilation unit 5 on the floor 7 of the room 100. There is.

The outdoor unit 3 is connected to the indoor unit 1 by a refrigerant pipe 9, and the ventilation unit 5 is connected to the indoor unit 1 via an air supply duct 10.

12 is the indoor air intake provided in the ceiling 2, 13 is the ceiling 2
A conditioned air outlet provided in the indoor unit 1 is connected via an outlet duct 14. This air conditioner can individually air-condition a desired floor or room in a building at any time, eliminating the need for a machine room for installing large-scale air-conditioning equipment, unlike the conventional central air-conditioning system. Since conditioned air is supplied from each room to each room, it is not necessary to install an air supply duct inside the building.

Then, if the cabinets of the outdoor unit 3, the ventilation unit 5 and the integrated air conditioning unit 4 are installed along the outer wall 6 in the shape of a rectangular parallelepiped having the same height and depth, the upper surface and the front surface of these units are flush with each other. Even if these units are installed in the room, the aesthetics of the room are not impaired, and the units can be installed not only by utilizing the recessed space between the adjacent columns 8 but also by taking in outside air into these units.

(Problems to be Solved by the Invention) In the above conventional air conditioner, the indoor unit 1
Refrigerant piping 9 for connecting the outdoor unit 3 to the outdoor unit 3 and electrical wiring, and the air supply duct 10 connecting the ventilation unit 5 and the indoor unit 1 and the electrical wiring are provided inside the pillar 8 so as not to spoil the aesthetics of the room 100. Since they will be buried, these burial works must be carried out along with the progress of the building construction work, and when troubles occur in the refrigerant pipes etc. buried after the building of the building, it is extremely difficult to solve these problems. Met.

(Means for Solving the Problems) The present invention has been proposed to solve the above problems, and its gist is to provide an indoor unit and an indoor unit installed in the ceiling of a building such as a building. In an air conditioner in which an outdoor unit installed on the floor is connected via a refrigerant pipe, an electric wire, etc., a decoration that surrounds only one surface facing the room of the building pillar of the building over its substantially entire height A pipe passage is formed by the decorative plate and the one surface of the body pillar by detachably fixing the plate, and the refrigerant pipe, the electric wire, and the like are laid in the pipe passage. It is in the piping structure.

(Operation) Since the present invention has the above configuration, the refrigerant pipe and the electric wiring can be installed in the pipe passage after the building is constructed with the decorative plate removed.

(Embodiment) One embodiment of the present invention is shown in FIG.

A decorative plate 20 is detachably fixed to one surface of the pillar 8, that is, the side surface facing the outdoor unit 3 so as to surround the outdoor unit 3 in a flush manner.
21 are configured. In the pipe passage 21, a refrigerant pipe 9 for connecting the outdoor unit 3 and the indoor unit 1, an electric wire 22, a water supply duct 23 and the like are laid.

Further, a decorative plate 30 is fixed to one surface of the pillar 8 facing the ventilation unit 5 so as to surround the same in a flush manner, and in the pipe passage 31 formed by the decorative plate 30 and the one surface of the pillar 8. An air supply duct 10 that connects the ventilation unit 5 and the indoor unit 1 and electric wiring 32 are laid.

Other configurations are similar to those of the conventional one shown in FIG. 3, and corresponding members are designated by the same reference numerals.

Then, after the building construction work is completed, the decorative plate 20 is removed, and the refrigerant pipe 9, the electric wiring 22, the water supply duct 23, etc.
After laying along one side, the decorative plate 20 is installed on the pillar 8
The refrigerant pipe 9, the electric wiring 22, the water supply duct 23, etc. are covered with the decorative plate 20 by being attached to, and the outer surface of the decorative plate 20 is flush with the pillar 8 and constitutes one side surface of the pillar 8.

In the above-described embodiment, the pipe passage 21 is formed by one side of the pillar 8 facing the outdoor unit 3, but when the building has a curtain wall structure, as shown in FIG.
The piping passage 21 can be formed by one surface of the pillar 8 facing the curtain wall 40.

(Effects of the Invention) In the present invention, the decorative plate that surrounds only one surface facing the room over the substantially entire height of the building pillar of the building is detachably fixed to the above-mentioned structure of the building board and the building pillar. Since the piping passage is formed by the one surface and the refrigerant pipe and the electric wire are laid in the piping passage, the piping passage can be formed only by fixing the decorative plate to the existing building pillar, so the piping passage can be formed. The number of parts is small and the number of steps is also small. Therefore, the piping passage can be manufactured easily, quickly, and at low cost.

In addition, since it is not necessary to lay refrigerant pipes, electric wires, etc. according to the progress of building construction work, it becomes easy to adjust the schedule of building construction work and refrigerant pipe laying work, and The cost can be reduced.

Since the installation work of the refrigerant pipes and the inspection and repair after the installation can be performed by the exposure work with the decorative plate removed, it can be performed extremely easily and in a short time.

And since the decorative plate surrounds only one side of the main body column over its substantially entire height, if the same appearance and color as the main body column are used, it will be integrated with the main body column to form one side of the column, There is no sense of incongruity.
