<P>PROBLEM TO BE SOLVED: To provide refrigeration equipment, in which the entire compressor mass flow can be used in substantially any temperature level without requiring usage of an auxiliary cryogen. <P>SOLUTION: The refrigeration equipment includes: at least one compressor operating to compress a cryogen that circulates in a cold cyclic path; a plurality of heat exchangers HX1, HX2, HX3, HX4, HX5 and HX6; and expansion devices TU1 and TU2 that operate at different temperature levels from each other. In the expansion devices, at least temporarily, at least one partial stream of the cryogen is expanded to generate cold. The refrigeration equipment is further provided with at least one additional expansion device TU3. The additional expansion device TU3 is embedded in the cold cyclic path in such a manner that the cryogen circulating in the cold cyclic path is, at least temporarily after cooling a cooling target, at least partially expanded in the additional expansion device TU3 to generate cold. <P>COPYRIGHT: (C)2013,JPO&INPIT |
