Open refrigerators are essential for showcasing perishable goods, but their energy consumption accounts for up to 70% of a supermarket’s total cooling costs. At present, there are a lot of literatures on the matching of display refrigerator units, refrigeration system optimization design and energy-saving measures. The energy-saving technology improvements of display refrigerators are mainly concentrated in the following three aspects.
Refrigerator Structural Improvements
Environmental Control
System Optimization
Replacing single large compressors with parallel small units saves 20% energy.
Implementing "supercooled" refrigerant cycles boosts cooling efficiency by 40%.
