    摘要： A cryogenic cell adapted to expose a fluid to selectable pressure and temperature conditions has a core filled with a cryogen and a space in selective, partial thermal communication with the core, the space being at least substantially airtight and adapted to be filled or evacuated with a compressible fluid that (1) increases or decreases thermal communication with the core in accordance with a pressure of the compressible fluid within the space, and (2) places contents of the space under the pressure of the compressible fluid. As heat exchange between the core and the space occurs, cryogen vapor is withdrawn from the core, compressed into liquid, and returned to the core. The core does not include a cold head.

    摘要： A distillation system receives a feed solution to produce residue and distillate. A heat pump includes parts of a first and second heat exchangers, a working fluid, a working fluid compressor, and an expansion device. The working fluid receives available heat energy from the distillate in the second heat exchanger, receives at least some additional heat energy in the working fluid compressor, and releases at least some of that heat energy into the feed solution in the first heat exchanger. The first heat exchanger receives the feed solution, permitting transfer of at least some heat energy into it. A separator receives the feed solution from the first heat exchanger and separates it into the residue and distillate. The second heat exchanger receives the distillate, permitting transfer of at least some heat energy back into the working fluid. And a distillate extractor directs the distillate out of the second heat exchanger.

    摘要： A compressor (31a, 31b) and an oil separator (35a, 35b) are provided in a refrigerant circuit (20). A flow-rate regulating valve (41a, 41b) is provided in an oil return pipe (40a, 40b) for returning a refrigerating-machine oil in the oil separator (35a, 35b) to the compressor (31a, 31b). A temperature sensor (42a, 42b) is provided downstream of the flow-rate regulating valve (41a, 41b) in the oil return pipe (40a, 40b). The oil-amount determiner (71a, 71b) determines whether an oil shortage state in which the amount of the refrigerating-machine oil held by the compressor (31a, 31b) is insufficient is present, on the basis of a measured value obtained by the temperature sensor (42a, 42b).
