Analysis of Hermetic Rolling Piston Type Compressor Noise, and Countermeasures
نویسندگان
چکیده
the noise profile. In order to locate the various sources of noise of the hermetic rolling position type compressor for room air conditioners, we experimentally analyzed the compressor noise and found that a main cause of the·noise was the acoustically amplified pressure pulsation in various parts of the compressor. Moreover, with reference to results of this noise source analysis, several procedures were devised for an effective reducti;on of pressure pulsation in various internal spaces of the compressor. As a result, the noise of the rolling piston type compressor could be reduced to a remarkable extent.

Noise Reduction of Rolling Piston Type Rotary Compressor
This paper refers to the noise reduction of the rolling piston type rotary compressor. In general. as the rolling piston increases its speed under the high compression ratio condition. the noise level increases steeply. We resume that this happens because a certain shock wave is produced in the comPression space. Then we could simulate the Phenomenon by the numerical analysis ( CACE method ) of...
