<p>Provided is a compressed refrigerator with higher efficiency and lower cost, compared with the conventional twin-stage refrigeration cycle compressed type refrigerator. The compressed refrigerator, with double-stage refrigerating cycle, comprises a high voltage condenser (22), a low voltage condenser (20), a high voltage evaporimeter (14), a low voltage evaporimeter (12), a compressor (18) connected to the high voltage condenser (22), and a compressor (16) connected to the low voltage condenser (20). The refrigerating fluid congealed by the high voltage condenser (22) is led to the low voltage condenser (20). In addition, a control valve (V1, V2) is arranged at a position at least between the compressor (18) connected to the high voltage condenser (22) and the high voltage condenser (22), the compressor (16) connected to the low voltage condenser (20) and the low voltage condenser (20), or the high voltage condenser (22) and the low voltage condenser (20).</p> |
