Motion of Rolling Piston in Rotary Compressor

This paper describes the behavior of a rolling piston in a rolling piston type rotary compressor under various operating conditions. Kinematic behavior of the rolling piston is discussed with attention to the friction forces acting on the rolling piston and the vane. Emphasis is on the following simulation approach. (1) The equation of motion of the rolling piston is solved in conjunction with ...

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...

Tribology Analysis in Rolling Piston Type Compressor

R & D Laboratories, DAIKIN INDUSTRIES,LTD. Sakai,Osaka,Japan This paper refers to an improvement of the lubrication in a rolling piston type rotary compressor. The lubrication conditions of lubricated surfaces are examined in running compressor and some parameters of them are numerically analyzed. It is elucidated from the investigation that,when unfavorable condition occurs,the metallic contac...

Experimental Statistical Energy Analysis Applied To A Rolling Piston-Type Rotary Compressor

Hermetic rotary compressors are one of the most important components in air-conditioners and refrigerators since they control both the performance and noise level of these products. Noise and vibration control of hermetic compressors should start with the identification of their sources of noise and vibration since the noise sources within a compressor play a determining role in the noise radia...
