ABSTRACT:
In a refrigerant cycle system, a gas-liquid separator has a gas-suction pipe for introducing gas refrigerant from the gas-liquid separator to a compressor. The gas-suction pipe has an open end opened in a gas-refrigerant area in the gas-liquid separator, a first suction hole, provided in a liquid-refrigerant area of the gas-liquid separator, for sucking liquid refrigerant containing lubricating oil, and a second suction hole provided in the gas-refrigerant area of the gas-liquid separator. The second suction hole for sucking gas refrigerant is formed in the gas-suction pipe at a downstream refrigerant side of the first suction hole. Therefore, a flow rate of gas refrigerant passing through around the first suction hole in the gas-suction pipe is decreased due to introduction of gas refrigerant by the second suction hole, thereby decreasing quantity of liquid refrigerant sucked from the first suction hole. Thus, liquid refrigerant is prevented from excessively returning to the compressor, even if the first suction hole is enlarged.
