Bowtie compressor with novel capacity modulation. 1. Design description and model development. 2. Model validation and parametric studies.

Author(s) : KIM J. H., GROLL E. A.

Summary

A novel refrigeration compressor with an integrated method of capacity modulation for use in domestic refrigerators/freezers is proposed and analyzed here. The compressor is called a bowtie compressor due to its two sector-shaped, opposing compression chambers forming a bowtie. The bowtie compressor modulates the cooling capacity by changing the piston stroke without changes in the clearance volume for better thermodynamic efficiency. The new compressor includes a unique off-center-line mechanism so that the piston stroke can be varied without changes in motor rotation. To investigate the feasibility of the proposed compressor, a simulation model has been developed. A detailed description of the bowtie compressor and its simulation model are presented in Part I of the paper. The validation of the simulation methodology and parametric studies to see how the proposed compressor performance can be improved are presented in Part II.
