To hold and fix a coil for an air conditioning system without using components for fixation, by a method wherein an engagement member for retaining a pipe fitted therein is formed by cutting open a part of the side wall of a support member for fixing a pipe body constructed of the pipe bent in a meandering manner and by machining the part to be shaped like a letter U practically.
A coil for an air conditioning system is constructed of a pipe 1 machined to be disposed in a meandering manner like a letter S, to be symmetric and to have a prescribed width, and the opposite end parts of the coil are fixed respectively by support members 2 each having a U-shaped section. In each support member 2, engagement members 3 are formed on the lateral side by swelling. These engagement members 3 are so provided as to coincide with the positions bends of the pipe 1 and the pipe 1 can be fixed by inserting it through the engagement members 3. The support member 2 is cut open by a height L3 and the part of a length L1 of a first face 2a is bent in the shape of a letter U so that the pipe 1 can be fitted inside. Thereby a holding part 4 is formed and the pipe 1 can be disposed inside.
