<p>A refrigerator according to the present invention comprises: a compressor (1); a condenser (2); a first heat exchanger (3) for further cooling a coolant cooled by the condenser (2); a first flow rate regulating means (4) and a second flow rate regulating means (5) for reducing the pressure of the coolant that has passed through the first heat exchanger (3); an evaporator (6) for evaporating the coolant which has been subjected to pressure reduction by the second flow rate regulating means (5); and an ejector (7) which uses the coolant that has passed through the first flow rate regulating means (4) as a drive flow and uses the coolant that has passed through the evaporator (6) as intake flow, and supplies these coolants to the compressor (1). Before the coolant that has passed through the first flow rate regulating means (4) is introduced into the ejector (7) as a drive flow, the first heat exchanger (3) performs heat exchange with the coolant cooled in the condenser (2), whereby the coolant cooled by the condenser (2) is further cooled. As a result, it is possible to provide a refrigerator that can restrict the generation of flash-gas within the coolant.</p> |
