<P>PROBLEM TO BE SOLVED: To provide a refrigerant circuit device that prevents cooling efficiency from being reduced by suppressing inflow of a liquid-phase refrigerant into a gas-phase refrigerant channel even if quality of a refrigerant flowing in a gas-liquid separator changes, and to provide a vending machine. <P>SOLUTION: The refrigerant circuit device includes a refrigerant circuit 10 including: a vaporizer 21; a compressor 22 which compresses a refrigerant vaporized by the vaporizer 21; a condenser 23 which condenses the refrigerant compressed by the compressor 22; an expansion mechanism 24 which adiabatically expands the refrigerant condensed by the condenser 23; and a gas-liquid separator 25 which separates the refrigerant adiabatically expanded by the expansion mechanism 24 into a gas-phase refrigerant and a liquid-phase refrigerant, and sends out the gas-phase refrigerant to the compressor 22 through a gas-phase refrigerant channel 32 while sending out the liquid-phase refrigerant to the vaporizer 21 through a liquid-phase refrigerant channel 31. The refrigerant circuit device further includes flow rate control valve 33 which constitutes the liquid-phase refrigerant channel 32, and controls the flow rate of the refrigerant in the liquid-phase refrigerant channel 32 in such a manner that the temperature of downstream refrigerant on the downstream side of the control valve 33 is higher than the temperature of upstream refrigerant on the upstream side of the control valve 33. <P>COPYRIGHT: (C)2013,JPO&INPIT |
