<p>The objective of the present invention is to achieve an excellent flow division characteristic under a wide range of usage conditions, without being influenced by the installation position of a refrigerant flow divider, or by manufacturing variations, or the like. This refrigeration cycle device is equipped with: a compressor that compresses a refrigerant; a condenser that condenses the refrigerant compressed by the compressor; an expansion valve (3) that decompresses the refrigerant condensed by the condenser; a flow divider (4) that is constructed separately from the expansion valve (3), and that divides the flow of the refrigerant decompressed by the expansion valve (3) into multiple flow paths formed in the interior of the flow divider; and an evaporator that vaporizes the refrigerant that has been divided by the flow divider (4). The expansion valve (3) and the flow divider (4) are arranged so as to satisfy the equations L/D <= 1.2 G0.36 and L/D >= 1.5, where L [m] is the distance from the throttle region (300) of the expansion valve (3) to the branching region (400) of the flow divider (4), D [m] is the inner diameter of a second connecting tube (32) of the expansion valve (3), and G [kg/(m2s)] is the mass velocity of the refrigerant flowing in the second connecting tube (32) of the expansion valve.</p> |
