Development and Properties of Commercial Refrigerator with Inverter Compressor

Abstract

We have developed the first commercial refrigerator with an inverter compressor which saves a significant amount of energy while maintaining the cooling performance. This refrigerator is provided with such functions as control of compressor rotation speed suitable for a commercial refrigerator, reduction of cold heat leak, and operation control of anti-condensation heater. In comparison with the conventional model, the new model achieved about 60% energy saving.
