摘要: The purpose of the present invention is to provide refrigerant circulation devices and a refrigerant circulation method which are capable of inhibiting a refrigerant comprising a hydrofluoroolefin (HFO) or hydrochlorofluoroolefin (HCFO) from decomposing and thereby generating an acid. One of the refrigerant circulation devices is a refrigerant circulation device (1) which includes a compressor (3), a condenser (5), expansion valves (9, 19), and an evaporator (11) that have been connected to each other by main piping (17a to 17e) to configure a refrigerant circulation circuit for circulating a refrigerant therethrough, and into which a refrigerant comprising an HFO or HCFO each having a carbon-carbon double bond in the molecular structure has been packed. The refrigerant circulation device (1) is equipped with a drive (15) for driving the compressor (3) via a speed increaser (13) and with a drive-cooling part (25) for cooling the drive (15) with the refrigerant condensed in the condenser (5), a desiccant which can trap water having been disposed in the evaporator (11) or the drive-cooling part (25).

摘要: An object is to provide centrifugal-separation oil separation means capable of improved cyclone efficiency and a refrigeration device equipped with the same. The oil separation means includes an outer cylinder (2) that extends in an axial direction; an inner cylinder (3) that passes through the interior of the outer cylinder (2) in the axial direction; a pair of end plates (4a, 4b) provided at both ends of the outer cylinder (2) in the axial direction; an inlet port (5) that is connected to the outer cylinder (2) near one of the end plates (4a) and that introduces an oil-containing fluid discharged from a compressor into a space (7) formed between the outer cylinder (2) and the inner cylinder (3) so as to swirl about the axis; an outlet port (6) that is connected to the outer cylinder (2) near the other end plate (4b) and that expels the fluid, from which the oil has been centrifugally separated, out of the space (7); and an oil discharge port, provided in the outer cylinder (2), for discharging the separated oil out of the space (7), wherein a partition plate (8, 9) that extends over at least part of a cross-section perpendicular to the axial direction to partition the space (7) in the axial direction is provided in the space (7).
