    摘要: A cryogenic gas is liquefied using a refrigeration system [101] thermally coupled at an evaporator [125] to a cold end of a gas supply system [103] within a dewar [116]. The refrigerator has a minimum temperature at an evaporator [125] above the boiling point of the gas at atmospheric pressure but below the boiling point of the gas at a high pressure. Thus, the gas is compressed [128] to high pressure so it condenses when cooled by the evaporator [125]. As it expands at a flow restrictor [148], a portion evaporates and cools a fraction to the temperature of the boiling point of the gas at atmospheric pressure, producing liquefied gas. Opening a purge valve [142] sends warm gas upward through heat exchange section [146] and out through a three-way valve [138] for defrosting. To reduce clogging, the gas supply valve [138] is controlled by a gas purity sensor [158].

    摘要: A method and an arrangement (100) for phase conversion. The arrangement has a space (30) including a working gas (33) and is arranged to include a generated standing sound wave, whereby said sound wave is generated such that the sum of added and consumed wave energy is greater than or equal to zero. Furthermore, the arrangement has a valve mechanism (10, 20) for provision and outflow of a quantity of a working gas or composition, consisting of at least one substance, in the space (30) and is arranged to work synchronously with the generated sound wave. The generated sound wave exposes the working gas or composition to pressure and temperature changes, whereby a gas compression creates an elevated temperature and a gas decompression creates a reduced temperature; and whereby a phase conversion, caused by the pressure and temperature changes, is obtained.
