Evaluation of PCM-CTES in maritime vessels

Abstract

Fishing vessels and fish transporting well-boats have varying cooling demand depending on operational mode. There is a possible benefit of peak shaving and energy saving with the use of cold thermal energy storage (CTES), which has been explored in this paper. Fishing vessels have limited space availability and the focus is therefore on compact and efficient systems. A CO2 system is suitable for that purpose due to its compactness and high volumetric refrigeration capacity. One application is to use ice slurry systems, which can be used to reduce the storage temperature of the fish and thereby keep the fish quality longer, compared with no chilling or chilling in refrigerated sea water (RSW). The chilling rates are faster, and it results in no significant damage to the fish surface.
