Abstract
The energy saving refrigeration system that is composed of a condensing unit and the refrigerated display cases has been developed. In this system, the DC inverter compressor controls the evaporating temperature and linear expansion valves control superheat at the outlet of evaporators in the refrigerated display cases. The target value of the evaporating temperature is calculated from the temperature difference between the refrigerated display cases and those cooling targets. The target value of superheat is set at 8 degrees that is the best value for energy conservation of the R404A refrigeration system. In this way, the electric power consumption of the refrigeration system is reduced by 31% in comparison with the conventional system
