<p>PROBLEM TO BE SOLVED: To easily connect a large number of branch pipes to each other, and also equalize a flow rate to be separated in a branch joint for a refrigerant pipe. SOLUTION: A branch joint for a refrigerant pipe is composed of a combination of bifurcated branch pipes 13 whose branch pipes 12 and 12 are branched off in the isometric two directions to a main pipe 11 and trifurcated branch pipes 16 branched off so that a crossed axes angle of the mutual tube axes of outside branch pipes 14 and 14 becomes an acute angle in the three directions to the main pipe 11 and the tube axis of an intermediate single branch pipe 15 becomes an almost bisector of the crossed axes angle, and the parallel number of the branch pipes 12 to 15 is increased by connecting the main pipe 11 to the tail ends of the respective branch pipes 12, 14 and 15, and a refriferant carrying pipe 6 to an indoor machine can be connected to the tail ends of the increased branch pipes 12 to 15 so as to be freely mountable/demountable.</p> |
