    摘要： 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 (CO2) is enclosed as said refrigerant, and the drop in heat transfer rate and the increase in pressure loss in the heat exchanger can be restrained to very low levels by keeping oil enclosing volume in the refrigerant circuit to the quantity of carbon dioxide gas (CO2) enclosed as refrigerant (weight %) to less than 40 weight % and more than 0, resulting in practical elimination of the increase in size and the impact on the drop in efficiency of the heat exchanger.

    摘要： It is an object of the invention to provide an inexpensive double-pipe heat exchanger having high performance and comprising an inner pipe and an outer pipe which constitute a double pipe without adding a heat-transfer facilitating material such as an inner fin. In the double-pipe heat exchanger having the inner pipe and the outer pipe, the outer pipe is dented from its outside toward its inside, thereby forming a plurality of projections which are dented toward the inner pipe. Examples of shapes of the projection are substantially conical shape, substantially truncated shape, substantially spherical surface shape, substantially cylindrical shape, substantially elliptic cylindrical shape and the like. The projections are disposed helically or in a staggered configuration such as to surround the inner pipe. With this structure, only by subjecting the outer pipe to simple working such as press working, it is possible to increase the turbulent flow of fluid flowing between the inner pipe and the outer pipe, and to facilitate heat transfer from fluid flowing in the inner pipe to fluid flowing between the inner pipe and the outer pipe.
