Abstract

1417110 Refrigerating BOC INTERNATIONAL Ltd 22 Nov 1972 [1 Dec 1971] 55808/71 Heading F4H In a gas refrigeration circuit comprising a compressor 4, a multi-stage heat exchanger 6, 8, 10, a Joule-Thomson expansion valve 12 and a heat exchanger 14 located in a cryostat 16, a valve 22 is provided in a by-pass passage 20 whereby the temperature of a heat-emissive load in the cryostat 16 may be prevented from falling below a predetermined value. The valve 22 is controlled by a temperature-responsive element 24 connected to a temperature-sensing element 26 in thermal contact with the heat exchanger 14. A proportion of the gas, e.g. hydrogen or helium, leaving the heat exchanger 6 is passed through an expansion turbine 18 to the return line downstream of the heat exchanger 10.
