Claim 5:
6. A system improving efficiency of a filter-type oil separator, the system comprising:
a compressor having a speed value and being configured to compress and pressurize a mixture of refrigerant and lubricant;
the filter-type oil separator configured to receive a first portion of the compressed mixture of refrigerant and lubricant from the compressor;
a bypass line configured to bypass a second portion of the compressed mixture of refrigerant and lubricant around the filter-type oil separator;
a bypass valve configured to receive the second portion of the mixture of refrigerant and lubricant and provide a bypass path around the filter-type oil separator for the second portion of the mixture; and
a controller configured to process one or more input signals, determine the speed value of the compressor based on the one or more input signals, and adjust the bypass valve based on the speed value,
wherein the controller further is configured to determine the speed value by calculating a value of refrigerant gas flow rate at a discharge side of the compressor and determining a correspondence between compressor revolutions per second (RPS) and the calculated refrigerant gas flow rate.
