Refrigeration prevents any damage to the cargo or decay of perishable foods, like growth of micro-organisms, oxidation, fermentation and drying out of cargo. Refrigeration Guide Book for Marine Engineer REFRIGERANT: A refrigerant is a substance that acts as a cooling agent by absorbing and giving off heat. The performance of these various methods is evaluated by comparing their results to experimental freezing time data obtained from the literature. The equipment, using voltage measurement and resistance measurement for dual diagnosis, determine the degree of insulation. Numerous semianalytical/empirical methods for predicting food freezing times have been proposed. will specify the acceptable noise levels for equipment. This article describes the many additional constraints a designer faces in refrigeration system design for naval applications. When developing refrigeration schemes, the design engineers seek to create optimal conditions of the system operation.
