A refrigerant flow divider is made up of an inlet pipe 12 through which refrigerant Xin flows in, a main body 11 of which the inside is a cavity, and a plurality of branching pipes 13 through which refrigerant Xout flows out. When the length of the above described main body 11 of the flow divider is L mm and the inner diameter of the above described main body 11 of the flow divider is D 2 mm, the relationship 2 ‰ L/D 2 ‰ 8 holds, and thus, a flow divider can be gained, where discrepancy (variation) in the flow rate ratio in the respective paths for the flow discharged from the outlet of the flow divider and entering the heat exchanger is small and pressure loss is small when there is a change of approximately ±10° in the installation angle, a change in the dryness of the refrigerant at the inlet (0.2 to 0.4) or a change in the flow rate of the refrigerant (50% to 100%). |
