ABSTRACT:
A refrigerating system of this invention includes at least one expansion chamber, at least one cryogenic accumulator, conduits connecting the expansion chamber and the cryogenic accumulator, and a substance to be cooled disposed between the expansion chamber and the cryogenic accumulator and in contact with one of conduits. It is a feature of this invention that a bypass conduit is disposed in parallel with one of the conduits in contact with the substance to be cooled. Thus, even when the substance to be cooled is placed away from one of the expansion chambers and one of the cryogenic accumulators, the refrigerating system of this invention can efficiently produce an extremely cold temperature of 40.degree. K. or less, and cool the substance to be cooled to a much lower temperature.
