Energy Saving Control System for Freezing-Refrigerating Warehouse

摘要

Freezing-refrigerating warehouses, which are designed for storing and sorting products in food distribution processes, are being required to be more energy efficient due to increasing electricity costs. Fuji Electric has developed an energy saving control system for centrally controlled freezing-refrigerating warehouses that optimizes the operation of the freezing-refrigerating equipment (refrigeration unit, unit cooler) inside warehouses while also making it possible to carry out efficient operation control. It has been confirmed that yearly power consumption in warehouses can be reduced by 12.3% through the adoption of enhancements such as optimized control for the unit cooler and pressure control for the low-pressure side of the refrigerator unit utilizing a unique algorithm for responding to load conditions inside the warehouse.
