<P>PROBLEM TO BE SOLVED: To allow a liquid-phase refrigerant in a gas-liquid separator to properly flow to a suction-side of a compressor. <P>SOLUTION: The gas-liquid separator 15 and the compressor 110 are arranged in adjacent to each other, and a liquid-phase refrigerant passage 17 for allowing the liquid-phase refrigerant separated by the gas-liquid separator 15 to flow out to a refrigerant suction side of the compressor 110, is formed on a region where the gas-liquid separator 15 and the compressor 110 are kept into contact with each other. The liquid-phase refrigerant passage 17 is provided with a passage opening/closing valve 18 for opening closing the passage, and a passage 154 at a gas-liquid separator 15 side in the liquid-phase refrigerant passage 17 is positioned above a passage 111b at the compressor 110 side so that the liquid-phase refrigerant in the gas-liquid separator 15 flows into the refrigerant suction side of the compressor 110 by self-weight, when the liquid-phase refrigerant passage 17 is opened by the passage opening/closing valve 18. <P>COPYRIGHT: (C)2012,JPO&INPIT |
