Abstract

A system and method for starting a compressor is provided. An amount of liquid refrigerant that is located in an oil sump of the compressor is determined. Using the determined amount of liquid refrigerant, a starting algorithm for the compressor is selected. The selected starting algorithm is configured to remove the determined amount of liquid refrigerant from the oil sump before the compressor reaches a preselected operating speed. The selected starting algorithm is then executed to start the compressor.
