<P>PROBLEM TO BE SOLVED: To provide an ejector cycle capable of operating one evaporator without stop, while defrosting from another evaporator, concerning an ejector cycle capable of cooling by using a plurality of evaporators simultaneously. <P>SOLUTION: A coolant circulation route 11 is constituted of a compressor 12, a radiator 13, an ejector 14 having a nozzle part 14a and an inflow port 14c from which a coolant is sucked into the ejector 14 by a high-speed coolant flow jetted out from the nozzle part 14a, and the first evaporator 15 whose coolant outflow side is connected to the suction side of the compressor 12. The coolant flow is branched between the radiator 13 and the ejector 14, and a throttle valve 17 having functions for depressurizing the coolant, adjusting the coolant flow rate and blocking the coolant flow, and the second evaporator 18 are arranged in the first branched passage 16 guiding to the vapor-phase coolant inflow port 14c. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
