Application of Taguchi Robust Design Method For Energy Efficiency Ratio and Noise of Compressors

摘要

As the concern for a global energy conservation and environmental protection are increased, it became more important thing to correspond with CFC depletion. Many companies have produced CFC-free refrigerators using alternatives refrigerants. Alternative refrigerants have merit such as global warming effect, but also have demerits such as lower efficiency, miscibility, increasing noise and poor reliability problems etc. Then we have to develop more efficient and robust compressors to satisfy a growing world-wide demand. In this paper, Taguchi robust design method with dynamic signal to noise ratio (SN) and two step optimization process have been used to optimize the head valve system for developing more efficient and low noise compressor. Also this method can be applied to rotary, scroll and other types of compressor.
