A Study on the Gas Pulsation in a Horizontal Scroll Compressor

Analytical and experimental investigations have been carried out on the gas pulsations in the discharge paths of a high-side horizontal scroll compressor, where the gas discharged from compression chamber is made to pass through several chambers inside the compressor shell. Model of Helmholtz resonators in series has been applied to this configuration to predict gas pulsation phenomena along the passages, and the calculation results have been compared with measured pressure time traces. Good agreements between the analytical and experimental results have been obtained. It has also been found that the compressor performance is somewhat affected by the size of individual chambers inside the compressor shell.
