<P>PROBLEM TO BE SOLVED: To facilitate adjustment of refrigerant flow rate in a plurality of evaporators, in an ejector type refrigeration cycle adapted to absorb heat from a cooling object space by the plurality of evaporators, and improve the cooling performance. <P>SOLUTION: This refrigeration cycle comprises a compressor 1; a radiator 13; an ejector 14; a first evaporator 15 connected to the outlet sie of the ejector 14; a branch passage 16 branching the outlet-side refrigerant of the radiator 13 on the inlet side of the ejector 14 and guiding it to a refrigerant suction port 14b; a throttle mechanism 17 and a second evaporator 18 arranged in the branch passage 16; and an internal heat exchanger 21 performing heat exchange between the high-pressure refrigerant on the outlet side of the radiator 13 and the low-pressure refrigerant on the suction side of the compressor 11. <P>COPYRIGHT: (C)2007,JPO&INPIT |
