Family design of scroll compressors with optimization

This paper proposes a systematic design method for developing a family of scroll-type compressor (STC). Except of using the general design optimization model includes multi-variable, direct search, inequality constraints, both interactive session and discrete variable design optimization skills have also been employed in this study. A practical design case on the 5200-9800 W capacity range of the STC family using R22 refrigerant has been implemented, and to achieve a common share percentage of 80% for the major components of this STC series plus a coefficient of performance based on electrical power input (COPel) of over 3.02 for each specified capacity of this family. Comparisons between calculated and measured results show that the maximum deviation of cooling capacity and COPel are below 2.53% and 1.69%, respectively. (C) 2005 Elsevier Ltd. All rights reserved.
