Abstract
Pressure pulsations are one of the major problem in compressors systems. Most of the phenomena caused by pressure pulsations had bad influence on the whole installation. Wide range of machines which induce pressure pulsations cause that there is no universal solution to this problem. Nowadays the refrigerating compressors with variable rotational speed are becoming increasingly important. In this article author presents results of a series of measurements of passive pressure pulsations attenuation for selected rotational speed which, according to the author’s thesis, depends mostly on the geometry of the damping element. Author also conducted a series of measurements with variable rotational speed for selected muffling elements. The results are shown in the paper, as well as discussion of the results and some conclusions.
