本発明は、天井裏を通して室外機から室内機に冷媒管を
導くための空気調和機の冷媒管の配管構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a piping structure for a refrigerant pipe of an air conditioner for guiding the refrigerant pipe from an outdoor unit to an indoor unit through the attic.
［背景技術］
従来、建物に空気調和機を設置する場合、室外機からの
冷媒管を壁の中に通して室内機に導いていた。このため
、設置作業に手間がかかり、設置作業の効率化が望まれ
ていた。[Background Art] Conventionally, when installing an air conditioner in a building, a refrigerant pipe from the outdoor unit was guided to the indoor unit through a wall. For this reason, the installation work is time-consuming, and it has been desired to improve the efficiency of the installation work.
一方、近年、建築現場での作業割合を減少させて、住宅
を効率的に建てるため、工場で住宅の構成部分をボック
ス状の住宅ユニットとして作製し、建築現場にこれらの
住宅ユニットを搬送して組み立てるようにした工業化住
宅が施行されるようになってきている。On the other hand, in recent years, in order to reduce the amount of work at the construction site and build houses efficiently, the components of the house are manufactured as box-shaped housing units in factories, and these housing units are transported to the construction site. Manufactured housing that can be assembled together is coming into use.
このような工業化住宅に空気調和機の冷媒管を配管し易
くするため、住宅ユニットに予め冷媒管のガイド管を設
置しておき、冷媒管を室外機が設置され′る所定の場所
に容易に配管できるようにした構造も提案されている（
実願平１−４８７６２）。この構造によれば、１階住宅
ユニット又は２階住宅ユニットにおいて室内機を壁を隔
てて室外機の横方向に設置し、壁を通して設けられてい
る直線状のガイド管に冷媒管を挿通して冷媒管の配管を
行う。In order to make it easier to install refrigerant pipes for air conditioners in such industrialized housing, a guide pipe for the refrigerant pipes is installed in the housing unit in advance, and the refrigerant pipes can be easily placed in the designated location where the outdoor unit will be installed. A structure that allows piping has also been proposed (
Jitsugan Hei 1-48762). According to this structure, the indoor unit is installed laterally to the outdoor unit across a wall in the first floor housing unit or the second floor housing unit, and the refrigerant pipe is inserted into a straight guide pipe provided through the wall. Perform piping of refrigerant pipes.
［発明が解決しようとする課題］
住宅によっては、空気調和機の室外機を１階住宅ユニッ
トの地面近くに設置し、室内機をｌ階又は２階住宅ユニ
ットの天井裏近くに設置する場合のように、室外機と室
内機が設置される高さ位置を変える必要も生じる。この
場合、冷媒管は住宅ユニットの壁内とフレームを通し、
更に１階又は２階住宅ユニットの天井裏を経由させて配
管しなければならなくなる。[Problem to be solved by the invention] In some houses, the outdoor unit of the air conditioner is installed near the ground of the first floor housing unit, and the indoor unit is installed near the ceiling of the first floor or second floor housing unit. Therefore, it is also necessary to change the height positions where the outdoor unit and indoor unit are installed. In this case, the refrigerant pipes run within the walls of the housing unit and through the frame.
Furthermore, the piping must be routed through the ceiling of the first or second floor residential unit.
しかし、通常の空気調和機の冷媒管は、鋼管（ＪＩＳ
Ｃ１２２０Ｔ−ＯＬ リン脱酸銅継目無管）が使用
されているため、ガイド管の配管経路に応じて曲げられ
ると、連続的に曲げ応力が掛かり、加工硬化を引き起こ
すことになる。従って、ガイド管の配管経路での曲げ角
度、曲げ回数等は、鋼管の加工硬化に大きな影響を与え
、場合によっては加工硬化により鋼管の配管が不可能に
なることもある。However, the refrigerant pipes of ordinary air conditioners are steel pipes (JIS
Since C1220T-OL (phosphorus deoxidized copper seamless pipe) is used, if it is bent according to the piping route of the guide tube, bending stress will be applied continuously, causing work hardening. Therefore, the bending angle, number of bends, etc. in the piping route of the guide tube have a large effect on the work hardening of the steel pipe, and in some cases, work hardening may make piping of the steel pipe impossible.
そこで、本発明は、ガイド管内を挿通させて冷媒管を配
管するにあたり、天井裏を経由して冷媒管を室外機から
室内機に導いても冷媒管が加工硬化を起こさないように
した空気調和機の冷媒管の配管構造を提供することを目
的とする。Therefore, the present invention provides an air conditioning system that prevents work hardening of the refrigerant pipe even when the refrigerant pipe is guided from the outdoor unit to the indoor unit via the ceiling when the refrigerant pipe is inserted through the guide pipe. The purpose is to provide a piping structure for the refrigerant pipes of the machine.

In the structure, the end of the guide pipe that guides the refrigerant pipe from the attic into the room is bent at an angle of 80 degrees or less, preferably 50 degrees or less with respect to the piping direction in the attic, and this end is It is characterized in that the end portion is fixed to the edge of the attic via a bracket that holds the end portion.
前記ガイド管の端部は、８０度より大きな角度で曲げら

天井裏の野縁に固定される部分とを有していればよい。The bracket includes, for example, a portion that holds a guide tube;
It suffices if it has a part that is fixed to the edge of the attic.
