To suppress a rise in a discharge temperature of a compressor of a refrigerating cycle device using a refrigerant having low warming potential, and to prevent deterioration in performance.
The refrigerating cycle device uses the refrigerant having the low warming potential as a refrigerant, and a plurality of small holes 119 are formed at different height in the vertical direction in a refrigerant outlet pipe 118 of an accumulator 117 in a cycle of the refrigerating cycle device. A liquid return amount is increased due to a small rise in a liquid level of a liquid refrigerant, and the periphery of the small holes 119 is restricted as shown in an accumulator restriction part 117S to reduce a space around the small holes 119 so as to secure a head difference by a small amount of the liquid refrigerant when it is stored. Thus, the liquid refrigerant storage amount for adjusting the liquid return amount can be minimized, and the deterioration in the performance can be minimized.
