THEORETICAL GAS PULSATION IN DISCHARGE PASSAGES OF ROLLING PISTON COMPRESSOR, PART II: REPRESENTATIVE RESULTS

摘要

Based on the mathematical models derived in part I, several kinds of the results are obtained. The first part of this paper presents the results of parameter studies without the gas pulsations. The purpose of this part is mainly to verify that the mathematical models and the computer program behave logically. The displacements of valve reed, when four parameters are changed one at a time, are presented and discussed. The behavior of valve reed is very important because it is a main source of noise and failure. The second part of this paper is concentrated on the gas pulsations in the discharge manifold of the rolling piston compressor. Pressures in the interior cavities and volume velocities of gas plugs are shown when the dimensions of several parts are changed. The results in this part can be a guide in designing rolling piston compressors because they show how the performance of compressor can be improved, in other word, a decrease of noise level. The Fourier spectra of the pressures and volume velocities are also presented to show the effectiveness of the muffler systems. The last set of results shows the effect of a side branch resonator which is attached to the valve cover of the modified rolling piston compressor.
