1. A method for improving the efficiency of a filter-type oil separator, the method comprising:
determining a gas flow rate;
determining a correspondence between a number of revolutions per second of a compressor and the gas flow rate;
determining a speed value based on the gas flow rate and the number of revolutions per second;
compressing a mixture of refrigerant and lubricant at a speed corresponding to the speed value;
responsive to compressing the mixture, providing a first portion of the mixture to a filter-type oil separator;
responsive to compressing the mixture, providing a second portion of the mixture to a bypass line; and
responsive to compressing the mixture, adjusting a bypass valve coupled to the bypass line based on the speed value.
