Abstract

1,087,675. Refrigerating; gas liquefaction apparatus. SULZER BROS. Ltd. July 13, 1966 [July 16, 1965], No.31516/66. Headings F4H and F4P. The low-temperature heat-exchanger 11 of a helium cycle refrigeration system is located in a pressure vessel 1 which contains gaseous helium and serves as a cold store for a load 2, e.g. an electromagnet, requiring intermittent cooling. Cold is transferred from the store to the load by a closed liquid hydrogen circuit 26 which is pressurized to prevent evaporation of the hydrogen by a vertical column 28 partially filled with liquid hydrogen, the vapour space of the column being connected to a chamber 29 maintained at ambient temperature. Chamber 29 may be charged with gaseous helium. The refrigeration system includes expansion turbines 9, 10, a compressor 5 and a buffer chamber 12 which is selectively connectible to the suction and discharge sides of the compressor to maintain a constant suction pressure. Column 28 may be omitted and circuit 26 filled with gaseous helium or, alternatively, helium from vessel 1 may be circulated through the load (Fig. 1, not shown). In a further embodiment (Fig. 4, not shown), vessel (1) is connectible into a helium liquefaction system via valves (36, 45), the system comprising a compressor (43), an aftercooler (44), counter-flow heat-exchangers (42, 37), a Joule-Thomson valve (38) and a liquid helium storage vessel (39).
