<P>PROBLEM TO BE SOLVED: To properly exert a refrigerating capacity even when load is changed in a cycle, in the ejector-type refrigerating cycle comprising a branching portion for branching refrigerant flow at an upstream side of a nozzle portion, and a plurality of evaporators. <P>SOLUTION: A nozzle portion-side outflow port 133a for allowing a refrigerant to flow out to an ejector side and a pressure reducing means-side outflow port 134a for allowing the refrigerant to flow out to a variable throttle mechanism side are formed in a storage space 130 of a gas-liquid separator 13. The nozzle portion-side outflow port 133a is formed in a first region LF1 in which the liquid-phase refrigerant exists in the storage space 130 in a normal operation, outside of a second region LF2 where the gas-phase refrigerant exists at a time when the amount of stored liquid-phase refrigerant becomes minimum, and the pressure reducing means-side outflow port 134a is formed in the second region LF2. Thus the liquid-phase refrigerant can be surely supplied to a suction-side evaporator at the downstream side of the variable throttle mechanism, and the refrigerating capacity can be exerted even in an operation of high load. <P>COPYRIGHT: (C)2009,JPO&INPIT |
