This paper refers to the development of new type rotary compressors suspended with twin springs in a lo~ s1de pressure shell. We compared several types of compress~rs, for example h1gh side pressure shell type, low side pressure shell type, external-suspended type, internal-suspended type, and so on, from the viewpoint of noise reduction, vibration control and transient phenomena such as start-...

This paper describes the experimental and analytical techniques used to identify and correct the noise and vibration concerns in a new family of reciprocating compressors. Operating sound, vibration and pressure pulsation data were acquired simultaneously on a prototype compressor. Analysis of this data led to two areas of concern. The first concern was identified using Operating Deflection Sha...

MINIATURIZATION OF THE FREON COMPRESSOR: THE BELLOWS PUMP James L. Kamm University of Toledo Thermal Engineering Company Toledo, Ohio All indicators point to the decade of the 1980's as the years of conservation. Whatever the technological "fix" of the future that will bring endless and sufficient energy supplies, if one exists, it will not be available within this time framework. Conservation ...

Thi~ paper is baaed on the working principle of scroll compressor and after investigating the ga~ flow condition, in especial analysis the gas leaking situation between two scroll parts mutual gearing, which influence the compressor performance very much. The working process calculating model is set up, employ the soroll compressor geometric parameter, size~ error of parts manufactured as well ...
