PROBLEM TO BE SOLVED: To improve vortex restraining performance. SOLUTION: This refrigerating unit has a refrigerating cycle. A liquid outlet 9 for discharging a liquid refrigerant to an expansion valve is formed in a bottom surface of a liquid storage tank 1. An annular first area for surrounding the liquid outlet 9, an annular second area for surrounding the first area, and an annular third area for surrounding the second area are arranged. A plate-like straightening vane 15 is erected and arranged in a radial shape in the first area with the liquid outlet 9 as the center, and a plate-like guide vane 17 is arranged in the third area for deflecting a flow of the liquid refrigerant flowing toward the liquid outlet 9 to either of the left and right, and a vortex with the liquid outlet 9 as the center is formed by correcting the flow of the liquid refrigerant by the guide vane 17. The vortex is weakened by the straightening vane 15 to restrain generation of respective vortex cores on a liquid level between the respective straightening vanes 15 when the liquid refrigerant flows along the straightening vanes 15 so that the vortex restraining performance can be improved.
