Abstract
The paper discusses experiences in development of coolers based on a single-stage compressor operating with mixed refrigerants. Data on the refrigeration capacity and Carnot efficiency were obtained for both one-stage and two-stage refrigeration cycles. It is assumed that the two-stage cycle employs only one phase separator, which can operate at different temperatures. Experimental data is presented for one-stage coolers that operate in a temperature range of 70 K to 200 K. Data on the efficiency of counter-flow heat exchangers and experience in the regulated throttle design are also discussed.
