A chilled water distribution system includes a chilled water loop in fluid communication with a plurality of buildings and also in fluid communication with a plurality of chiller stations. A monitoring and control system communicates with one of the chiller stations, hereinafter referred to as a “controlled” chiller station because it is configured with one or more variable frequency drives that are controlled by the monitoring and control system to modulate the speed of at least one chiller station component such as, but not limited to, a pump or a fan. By way of this modulation process, a differential pressure of the chilled water loop may be maintained in a “sweet spot” so as to optimize chiller station output while minimizing chiller station energy consumption.

Refrigeration system for chilled storage container

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 differential across air/ice interface and maintains the quality of the ice.
