Claim 13:
14. A method of improving efficiency of a filter-type oil separator in a system including a compressor, the filter-type oil separator, and a bypass line configured to bypass the filter-type oil separator, the method comprising:
compressing and pressurizing, by the compressor, a mixture of refrigerant and lubricant;
receiving, by the filter-type oil separator, a first portion of the compressed mixture of refrigerant and lubricant from the compressor;
bypassing a second portion of the compressed mixture of refrigerant and lubricant around the filter-type oil separator with the bypass line;
adjusting a bypass valve to a first predetermined percentage of openness in response to determining the speed value exceeding a threshold;
adjusting the bypass valve to a second predetermined percentage of openness, the second predetermined percentage being more than the first predetermined percentage, in response to determining the speed value increased; and
adjusting the bypass valve to a third predetermined percentage of openness, the third predetermined percentage being less than the first predetermined percentage, in response to determining the speed value decreased.
