Energy analysis of the direct and indirect refrigerating systems applied to refrigerated ships

Abstract

In the paper different design solutions of refrigerating systems are considered, which are applicable to the universal refrigerated ships employed in shipping of refrigerated cargo within a wide range of temperature. The example systems are analyzed and compared to each other with the use of the exoergic efficiency criterion. Example calculations of defrosting cycle influence on the exoergic efficiency of both analyzed systems are also presented.
