Acoustic prediction and noise control of a refrigeration compressor
… of the acoustic radiation from a Bristol H25A refrigeration compressor are investigated. For the acoustic prediction, a modal decomposition approach is used. To this end, a boundary element model of the shell is created, and it is used to compute the modal radiation efficiency curves of the …

Finite element modeling of a refrigeration compressor for noise prediction applications
… finite element model of a hermetic reciprocating compressor for noise prediction applications. Inherent difficulties in developing the finite element model of a complicated structure are discussed and appropriate modeling strategies are evolved. The development of the complete compressor finite …

Collision Analysis of the Reversible Crankshaft Mechanism in a Convertible Refrigeration Compressor
… of a reversible two-cylinder refrigerant compressor manufactured by Bristol Compressor Incorporated. This compressor contains a specialized linkage that causes the compressor to transition from a two-cylinder compressor to a single-cylinder compressor when the direction of rotation of the …

Analysis of the Dynamic Interferences Between the Stator and Rotor of a Refrigeration Compressor Motor
… finite element model of a hermetic, single-vane compressor and a single-phase alternating current induction motor assembled in a common housing. The manufacturer of this unit is experiencing a high scrap rate due to interference during operation between the stator and rotor of the motor. The …

Identification of sound transmission paths within a hermetic reciprocating refrigeration compressor via multiple-input/single-output modeling
… paths of sound within a reciprocating refrigeration compressor have been investigated and ranked. By investigating the nature of sound propagation within reciprocating compressors, it is hoped that compressor manufacturers can effectively formulate strategies for compressor sound …

Dynamic finite element modeling and analysis of a hermetic reciprocating compressor
Dynamic finite element modeling and analysis of a refrigeration compressor was investigated as part of a noise emission study. Natural frequencies and normal mode shapes were calculated for the major structural components of the compressor. The components were later combined to form a model of the …

Tribological studies of surface texturing for application in air-conditioning and refrigeration compressors
Operating conditions such as load and speed of compressors are getting more aggressive to improve efficiency. Also, protection from beneficial surface layers, such as ferrous chlorides, on the critical interfaces is compromised as the refrigerants industry is moving from traditional (CFC/HFC) to …
