<p>PURPOSE: To easily control the refrigerant distributing amount of a distributor by forming the both ends of the distributor as outlet side tubes, providing an inlet side tube substantially at the center of the outlet side tube, and inserting a pipe having a small diameter to the end of the outlet side tube in the distributor for partly dividing a refrigerant circuit into a plurality. CONSTITUTION: The inner diameter of an inlet side tube 62 provided at the center of a distributor 61 is formed equal to or larger than those of outlet side tubes 64a, 64b of both ends, and the inner diameter of a pipe inserted to one of the tubes 64a, 64b is reduced thinner than that d3 of the outlet side tube 64a. Thus, the flow of refrigerant fed to the distributor 61 via a refrigerant tube 66 is made scarcely changed in the gravity direction from the part of the tube 52, and the adherence of the flow to the inner wall 65 of the branch scarcely occurs so that the refrigerant can be freely distributed. Thus, the distribution refrigerant ratio to the tubes 64a, 64b is stably maintained despite the circulation amount, the dryness and the path configuration change of the refrigerant according to the size of the inner diameter of the pipe.</p> |
