摘要： An apparatus includes a first compressor (410), a first load (430), a second compressor (415), a second load (435), a first heat exchanger (450), and a second heat exchanger (455). The first compressor (410) compresses a first refrigerant. The first load (430) uses the first refrigerant to remove heat from a space proximate the first load (430). The first load (430) sends the first refrigerant to the first compressor (410). The second compressor (415) compresses a second refrigerant. The second load (435) uses the second refrigerant to remove heat from a space proximate the second load (435). The second load (435) sends the second refrigerant to the second compressor (415). The first heat exchanger (450) receives the first refrigerant from the first compressor (410). The first heat exchanger (450) transfers heat from the first refrigerant to a fluid. The second heat exchanger (455) receives the second refrigerant from the second compressor (415). The second heat exchanger (455) transfers heat from the fluid to the second refrigerant.

摘要： A heat exchange tube combines an external surface feature, for example having crushed fins and cavities, which can have very high boiling enhancement characteristics, with an internal surface feature, for example having high performing intersecting helices, e.g. "cross hatched" with an intersecting helix angle. The new tube can provide a high performing tube in a shell and tube evaporator that can be relatively smaller, more efficient, and that can use relatively lower refrigerant charge.

摘要： The present invention provides a method of accelerating cool down of a target member of a cryogenic system to a cryogenic operating temperature. The method comprises the steps of cooling a target region of a cryogenic system with a first cooling apparatus, the first cooling apparatus being adapted to cool the target region to a first temperature by thermal conduction between the first apparatus and the target member, and having a first cooling power at the first temperature; and cooling the target member of the cryogenic system from the first temperature to an operating temperature using a cryocooler, where the first cooling power of the first cooling apparatus at the first temperature is greater than the cooling power of the cryocooler at the first temperature. This allows a target member of a cryogenic system to be cooled more rapidly than when conventional methods are used.

摘要： The invention provides a fin-and-tube heat exchanger using a return bend tube that allows further enhancement of the evaporative performance of the heat exchanger. The fin-and-tube heat exchanger, where a refrigerant is supplied inside tubing, has a hairpin tube portion where a plurality of hairpin tubes are arranged, a return bend tube portion where there are arranged a plurality of return bend tubes joined to respective hairpin tube ends of the hairpin tube portion, and a fin portion comprising a plurality of fins arranged at a predetermined spacing on the outer surface of the hairpin tubes. The heat exchanger comprises first grooves formed on the tube inner surface of the return bend tube. A first groove pitch (P1) of the first grooves in a cross section perpendicular to a tube axis, and a second groove pitch (P2) of spiral-shaped second grooves formed on the inner surface of the hairpin tube in a cross section perpendicular to a tube axis, satisfy a groove pitch ratio (P1/P2) of 0.65 to 2.2, while a first groove cross-sectional area (S1) per groove of the first grooves in a cross section perpendicular to the tube axis, and a second groove cross-sectional area (S2) per groove of the second grooves in a cross section perpendicular to the tube axis satisfy a groove cross-sectional area ratio (S1/S2) of 0.3 to 3.6.
