Discussion on leaking characters in meso-scroll compressor

The leakage is unavoidable and has considerable influence on the performance of a scroll compressor. In a meso-scale scroll compressor, the working gas leakage is more serious because the gaps between the scroll plate pairs are more difficult to be sealed than the case in a normal scale scroll compressor. This paper analyzes the leakage and related factors with a simplified model, and discusses the performance that resulted from gas loss due to both leakages from tangential and axial directions in meso-scale compressors. The discussion and related results are helpful to determine some key parameters in the design and manufacture of meso-scroll compressors. (C) 2009 Elsevier Ltd and IIR. All rights reserved.
