Abstract
The scroll-type compressor features lower noise, due to less pulsation of gas pressure, than that of the rotary-type compressor. Nevertheless, at high rotation speed, the pulsation of gas pressure produces a significantly larger influence on total noise. In the present report, the author clarifies the relationship between noise and gas pressure pulsation is generated in the inner spaces of the hermetic shell in the scroll-type compressor as well as the relationship between acoustic characteristics and the pulsation of gas pressure. Experimental analysis and FEM analysis for acoustic field are performed and experiments for a scroll-type compressor with various newly-devised discharging mufflers and with a Helmholtz resonator near the discharging port for reduction of the compressor noises are presented.
