PROBLEM TO BE SOLVED: To omit heat insulating material winding work, and sharply raise the work efficiency, by providing an indoor machine with a rear pipe fixer in the section opposed to a pipe connector, and then, combining this rear pipe fixer and a front pipe fixer which accommodates a pipe section in the vicinity of the pipe connector and besides fixes it in heat insulating condition. SOLUTION: The end of a crossover pipe Pb from an outdoor machine is connected through a pipe connector 17 to the end of the auxiliary pipe Pa at the terminal of a heat exchange pipe. A pipe fixer 25 is constituted by combining a front pipe fixer 30 and a rear pipe fixer 40. Front and rear pipe fixers 30 and 40 comprise casings with their rear side or front side open and the heat insulating material of foaming styrene stuck to their inside, and the brims of the openings abut correctly on each other, and the heat insulating materials projecting from these brims contact closely with each other, too. Within the pipe fixer 25, the pipe connector 17, the auxiliary pipe Pa to be connected with this, and a part of the crossover pipe Pb are inserted and accommodated, and they are fixed in heat insulating condition. |
