PROBLEM TO BE SOLVED: To prevent only a liquid refrigerant from returning to a compressor and ensure reliability of the compressor in an accumulator of a cooling apparatus using non-dissolution oil having a lower dissolution with a refrigerant. SOLUTION: When a load of an evaporator is very sharply changed, a refrigerant 2 having higher moisture flows into a body 1 from the evaporator through an inflow piping 3, and the high moisture refrigerant 2 becomes the liquid refrigerant 2 in the body 1 and stays in the same. Herein, a first hole 8 formed in a return piping 4 is formed in the vicinity at a height of a liquid level when a maximum amount of the liquid refrigerant 2 stays, whereby only the liquid refrigerant 2 is prevented from being sucked in from the first hole 8, and further liquid in the compressor is prevented from being compressed, and further normal lubrication is ensured without permitting the liquid refrigerant 2 to wash out non-dissolution oil 9 film on a slide section of the compressor.
