Abstract:

A dual-phase refrigeration system for chilled storage containers (CSC) aboard boats maintains cold temperatures in the CSC by chilling the airspace in the upper portion of the CSC. A cooling liquid is circulated through coils installed on an interior sidewall about an upper margin of the CSC. The cooling liquid chills the air in the upper portion of the CSC which creates a thermodynamic airflow within the CSC which aids in cooling. The temperature of the cooling liquid is maintained by a heat exchange with a Non-Ozone Depleting Hydrofluorocarbon (NODHFC) refrigerant which, in turn, is cooled by a heat exchange with circulating water sourced from the body of water supporting the boat. If ice is added to the CSC, the cooling liquid in the coils reduces the air temperature and optimizes thermodynamic airflow to eliminate the temperature differential across air/ice interface and maintains the quality of the ice.
