Drink Showcase Equipped with Inverter Freezer

摘要

In recent years, the impact of earthquakes has increased the demand for replacing products with more energy saving alternatives. Furthermore, convenience stores are also requiring open showcases that increase the product display area. Fuji Electric has developed an 8-shelf showcase that utilizes an inverter freezer and has a display area 1.57 times greater than previous products. The unit makes use of a new scroll compressor, while also adopting a new cooling system that utilizes segmented airflow, thus enabling the unit to achieve optimal inverter control that saves energy and stabilizes temperatures inside the showcase. We have also developed a mechanism that uses the evaporation fan to implement forced evaporation of drain water with the aim of saving energy and reducing the operation. The unit achieves a 67% reduction in power consumption per unit area.
