<P>PROBLEM TO BE SOLVED: To provide a refrigerating system striking a balance between the defrosting with respect to an evaporator at a low outside air temperature, and the maintenance and improvement of hot-water supply capacity. <P>SOLUTION: This refrigeration cycle device using an ejector includes: a compressor 1; a first radiator 2; a second radiator 7; the evaporator 5; the ejector 3; a gas-liquid separator 4; a vortex tube 6; a first bypass passage A which is branched off from a second flow path 20 connecting the first radiator 2 and the inlet of the ejector 3 and which is connected to the introducing port of the vortex tube 6; a second bypass passage B for connecting the high temperature side outlet of the vortex tube 6 and the inlet of the ejector 3 through the second radiator 7; a third bypass passage C which is branched off from the second bypass passage B on the upstream side of the second radiator 7 and which is connected to the inlet of the ejector 3 through the evaporator 5; and a fourth bypass passage D for connecting the low temperature side outlet of the vortex tube 6 and the gas-liquid separator 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
