Design and Development of a Variable Rotary Compressor
نویسندگان
چکیده
The following paper describes the design and development issues with a variable capacity control 2-stage rolling piston compressor. The control mechanism was based on a gas-bypass control strategy. During the development, design issues surfaced that were not significant in the case of the full capacity version of the compressor. When the capacity was reduced, loss generation mechanisms remained constant. These resulted in higher discharge temperatures and lower compressor efficiencies. Improvements were made to reduce losses in line with capacity reductions.
