<p>PROBLEM TO BE SOLVED: To improve distribution performance of a lubricant included in a refrigerant with a simple configuration, in a refrigerant distributor having a branch pipe extended in the vertical direction.SOLUTION: A refrigerant distributor includes: a branch pipe 70 having an inlet pipe portion 71 into which a refrigerant where a lubricant is mixed, flows, and first and second outlet pipe portions 72, 73 positioned at a lower part with respect to the inlet pipe portion 71, and branched from the inlet pipe portion 71, and vertically extended; and a distributing portion 74 disposed inside of the branch pipe 70, and distributing the lubricant mixed in the refrigerant flowing into the inlet pipe portion 71, to the outlet pipe portions 72, 73. The distributing portion 74 has a cylindrical joining portion 741 joined to an inner wall surface of the inlet pipe portion 71, and first and second projecting pieces 742a, 742b respectively extended toward the inside of the outlet pipes 72, 73, and the projecting pieces 742a, 742b are separated from inner walls of the outlet pipe portions 72, 73, and tapered from an upstream side of the refrigerant flow to a downstream side.</p> |
