然而，在将上述室内单元安装到室内的墙壁上时，根据室内单元的安装场所，作业人员必须将连接配管102弯曲。在该情况下，作业人员使在连接配管102中沿水平方向延伸的部分沿上下方向移动、或使其以第一制冷剂配管103为中心转动。由此，在第一制冷剂配管103与第二制冷剂配管104的连接部106产生扭转或弯曲的应力。由于该连接部106由彼此不同的金属形成，因此难以承受扭转或弯曲的应力。However, when the above-mentioned indoor unit is attached to the indoor wall, a worker must bend the connecting pipe 102 depending on the installation location of the indoor unit. In this case, the operator moves the portion extending in the horizontal direction of the connection pipe 102 vertically or rotates it around the first refrigerant pipe 103 . As a result, torsional or bending stress is generated in the connection portion 106 between the first refrigerant pipe 103 and the second refrigerant pipe 104 . Since the connecting portion 106 is formed of metals different from each other, it is difficult to withstand twisting or bending stress.
因此，根据上述以往的空调机的室内单元，存在第一制冷剂配管103与第二制冷剂配管104的连接部106破裂的危险性大这样的问题。Therefore, according to the above-mentioned conventional indoor unit of the air conditioner, there is a problem that the connection portion 106 between the first refrigerant pipe 103 and the second refrigerant pipe 104 is likely to be broken.

Therefore, since the connecting portion of the other end of the first refrigerant pipe 5 for liquid and one end of the second refrigerant pipe 6 for liquid is arranged at the end of the bent portion 5b on the side of the flared pipe joint 9 for liquid and the first end of the second refrigerant pipe for liquid. Between the ends of the two refrigerant pipes 6 on the side of the flared pipe joint 9 for liquid, it is possible to reduce the risk of rupture of the joint.
此外，上述液体用第一制冷剂配管5的另一端部与液体用第二制冷剂配管6的一端部的连接部配置在比弯曲部5b的液体用喇叭管接头9侧的端部与液体用第二制冷剂配管6的液体用喇叭管接头9侧的端部之间的中间靠液体用喇叭管接头9侧的位置。由此，能够可靠地降低在上述连接部产生较大的扭转及弯曲的应力的可能性。In addition, the connecting portion between the other end of the first liquid refrigerant pipe 5 and one end of the second liquid refrigerant pipe 6 is arranged at the end of the bent portion 5b on the liquid horn joint 9 side and the liquid end. The middle between the ends of the second refrigerant pipe 6 on the liquid flared pipe joint 9 side is located on the liquid flared pipe joint 9 side. Thereby, it is possible to reliably reduce the possibility that a large torsion and bending stress will be generated in the connection portion.
此外，即使使上述气体用第一制冷剂配管7的下部侧直线部7c和气体用第二制冷剂配管8靠近气体用第一制冷剂配管7的侧部侧直线部7a，也能够通过气体用第一制冷剂配管7和气体用第二制冷剂配管8得到与上述的作用效果同样的作用效果。In addition, even if the lower side straight portion 7c of the first gas refrigerant pipe 7 and the second gas refrigerant pipe 8 are brought closer to the side side straight portion 7a of the first gas refrigerant pipe 7, it is possible to The first refrigerant pipe 7 and the second gas refrigerant pipe 8 obtain the same effects as those described above.
此外，由于上述热交换部3和各传热管4分别由铝或铝合金形成，因此能够减少制造成本。Moreover, since the heat exchange part 3 and each heat transfer tube 4 are respectively formed of aluminum or an aluminum alloy, the manufacturing cost can be reduced.
在上述实施方式中，液体用第一制冷剂配管5的另一端部与液体用第二制冷剂配管6的一端部的连接部配置在比弯曲部5b的液体用喇叭管接头9侧的端部与液体用第二制冷剂配管6的液体用喇叭管接头9侧的端部之间的中间靠液体用喇叭管接头9侧的位置，但也可以配置在比弯曲部5b的液体用喇叭管接头9侧的端部与液体用第二制冷剂配管6的液体用喇叭管接头9侧的端部之间的中间靠弯曲部5b侧的位置。In the above-described embodiment, the connection portion between the other end of the first liquid refrigerant pipe 5 and the one end of the second liquid refrigerant pipe 6 is arranged at the end of the bent portion 5b on the liquid flare joint 9 side. The position between the end of the second liquid refrigerant pipe 6 on the side of the liquid flared pipe joint 9 is closer to the liquid flared pipe joint 9 side, but it may be arranged on the liquid flared pipe joint than the bent portion 5b. The position between the end portion on the 9 side and the end portion on the liquid flare joint 9 side of the second liquid refrigerant pipe 6 is on the side of the bent portion 5b.
在上述实施方式中，气体用第一制冷剂配管7的另一端与气体用第二制冷剂配管8的一端的连接部配置在比弯曲部7b的气体用喇叭管接头10侧的端部与气体用第二制冷剂配管8的气体用喇叭管接头10侧的端部之间的中间靠气体用喇叭管接头10侧的位置，但也可以配置在比弯曲部7b的气体用喇叭管接头10侧的端部与气体用第二制冷剂配管8的气体用喇叭管接头10侧的端部之间的中间靠弯曲部7b侧的位置。In the above-described embodiment, the connection portion between the other end of the first gas refrigerant pipe 7 and one end of the second gas refrigerant pipe 8 is arranged at a position where the end of the bent portion 7b on the gas flared joint 10 side is connected to the gas. The middle between the ends of the second refrigerant piping 8 on the side of the gas flare joint 10 is closer to the gas flare joint 10 side, but it may be arranged on the gas flare joint 10 side than the bent portion 7b. The position between the end of the second refrigerant pipe for gas and the end of the second gas refrigerant pipe 8 on the side of the flared pipe joint 10 for gas is on the side of the bent portion 7b.
在上述实施方式中，也可以将液体用第一制冷剂配管5、液体用第二制冷剂配管6、气体用第一制冷剂配管7和气体用第二制冷剂配管8用隔热材料覆盖而构成一体。In the above embodiment, the first refrigerant pipe for liquid 5, the second refrigerant pipe for liquid 6, the first refrigerant pipe for gas 7, and the second refrigerant pipe for gas 8 may be covered with a heat insulating material. form a whole.
对本发明的具体实施方式进行了说明，但本发明不限于上述实施方式，可在本发明的范围内进行各种变更来实施。Although specific embodiments of the present invention have been described, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention.
