<p><P>PROBLEM TO BE SOLVED: To prevent generation of water hammersound from a bending part. <P>SOLUTION: A muffler 50 is disposed in a rising part 672 of a U-shaped refrigerant pipe 67 of the low-pressure refrigerant piping 65 in the refrigeration cycle device for a vehicle. A hollow part 500, inside the muffler 50, is formed to expand toward the lower side of the vehicle from a refrigerant inlet part 51 side. Although the liquid-phase refrigerant may be collected in the hollow part 500, while a compressor 10 is stopped, a gas pathway through which the gas-phase refrigerant flows is formed in the liquid-phase refrigerant on the upper side of the vehicle, while the liquid-phase refrigerant is collected in the hollow part 500. As a result, the gas refrigerant flows into the inlet side of the compressor 10 through a refrigerant outlet 52 by the suction force of the compressor 10, when the compressor is started. Here, the refrigerant does not flow out of the refrigerant outlet 52 to start to rise through the U-shaped refrigerant pipe 67, even if the suction force of the compressor 10 acts on the liquid-phase refrigerant in the hollow part 500. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
