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.

摘要： In a refrigerating cycle device using carbon dioxide as a refrigerant, there exists a problem that the provision of a receiver at a low-pressure side increases cost and volume due to a pressure resistance design necessary for ensuring safety. By adjusting a refrigerant holding quantity of a first heat exchanger in such a manner that a refrigerant pressure of the first heat exchanger 13 is changed by operating a first decompressor 12 and a second decompressor 15, an imbalance of a refrigerant quantity between time for space cooling and time for heating or dehumidifying can be alleviated and hence, it is possible to perform an operation of the refrigerating cycle device with high efficiency with a miniaturized receiver or without providing the receiver.
