OIL DROPLET GENERATION AND CONTROL IN ROLLING PISTON TYPE COMPRESSORS

摘要

This paper addresses the generation and control of oil droplets in rolling piston type refrigerant compressors at speeds greater than 5000 RPM. This work is part of the development of a variable speed compressor which addresses the problem of critically low oil sump levels that can occur at these extreme speeds. This paper identifies the dominant mechanism of oil droplet generation based on experimental and analytical results.
