To prevent heat transfer inhibition and an increase in pressure loss due to refrigerating machine oil discharged into a cycle, and to provide a compact and highly efficient refrigerating cycle apparatus using carbon dioxide gas (CO2). In a refrigerating cycle apparatus having at least a compressor, a radiator, a decompressor, a vaporizer and piping for successively connecting them, and provided with a refrigerant circuit in which refrigerant circulates in the compressor, the radiator, the decompressor, the vaporizer and the piping, carbon dioxide gas (CO...
1. A refrigerating cycle apparatus comprising at least a compressor for raising the pressure of refrigerant; a radiator for cooling the refrigerant raised in pressure by said compressor; a decompressor, arranged further downstream of the refrigerant flow than said radiator, for decompressing and expanding said cooled refrigerant; a vaporizer for heating the refrigerant decompressed by said decompressor; and piping for consecutively connecting said compressor, said radiator, said decompressor and said vaporizer, and provided with a refrigerant circuit in ...
