CYCLONE REFRIGERATION DEVICE, CYCLONE COOLNESS/HEAT RECOVERY UNIT, AND HEAT PUMP SYSTEM PROVIDED WITH SAID CYCLONE REFRIGERATION DEVICE OR CYCLONE COOLNESS/HEAT RECOVERY UNIT

摘要

The present invention is provided with a cylinder part 1, an exhaust pipe 3, a cooling part 4 having a cavity 4a that passes through an internal space 1b of the cylinder part, a refrigerant inflow pipe 5, and a decompression device 6. A liquid-phase refrigerant that has been condensed under high pressure is supplied to a refrigerant supply pipe and is decompressed by the decompression device to form a solid-gas two-phase refrigerant. The solid-gas two-phase refrigerant flows into the internal space of the cylinder part and forms a downward spiral, and is separated into a solid-phase refrigerant S and a gas-phase refrigerant. The solid-phase refrigerant S accumulates in the cavity, and the gas-phase refrigerant forms an upward spiral passing from a bottom part of the cavity through the interior space inside the downward spiral and flows out from the exhaust pipe. The present invention is also provided with: pipelines 7a, 7b through which a fluid to be cooled circulates, said pipelines 7a, 7b through which a fluid to be cooled circulates extending through the cavity of the cooling part, and a fluid to be cooled from a cooling load 9 is circulated through the interior of the pipelines through which a fluid to be cooled circulates; a heat exchanger 8 provided to a portion of the pipelines through which a fluid to be cooled circulates that is within the cavity, the heat exchanger 8 performing heat exchange between the solid-phase refrigerant S and the fluid to be cooled; and a pump 10 that circulates the fluid to be cooled.
