In a refrigerating apparatus using an HFC group refrigerant, the performance is improved by increasing the refrigerating capacity and a stable operation is made possible. In order to achieve this, a cycle system in a refrigerator is structured so as to connect a compressor, a condenser, a liquid receiver and a supercooler in this order. In an air-cooled separation type refrigerator, the liquid receiver is disposed within an air-cooled type condenser unit. Further, in the case where a flush gas is liable to be generated in a liquid pipe, a vapor-liquid separator is disposed within the compressor unit integral with an accumulator and separated therefrom by a partition plate.
