摘要

The effects of thermal resistance and internal irreversibilities on the performance of combined cycles (combined four stage vapour compression cycles and solar driven combined Brayton power and refrigeration cycles) for cryogenic refrigeration were investigated. Improved equations for the coefficient of performance of the systems under consideration were obtained. It was found that for the same cooling load and cryogenic temepraturer, the performances of the two systems are almost the same, regardless of greater energy consumption of the combiend vapour compression cycle.
