Design optimization of a marine refrigeration system with waste heat recovery channel

Abstract

This paper presents the design of an optimized marine refrigeration system to be used as a preservation facility for fishermen on boats. This aims to help preserve and maintain the high quality of the catch during fishing operations. This is to replace the manual ice box method. The system is tested in an actual environment offshore. The lowest temperature reached inside the refrigeration when full load is -1.7°C with a maximum time of 6 hours, while the temperature of the fish inside the refrigeration is 2.5°C. These results show the capability of the enhanced marine refrigeration system to achieve the desired temperature for the catch to maintain its good quality. In addition, the usability and user experience survey results indicated that the target beneficiaries agreed that the following aspects of the marine refrigeration system include usefulness and functionality, ease of use, design capacity, dimension, aesthetics, and kerosene as the resources used are excellent.
