Abstract
Systems, methods, and computer-readable mediums are provided for improving the efficiency of a filter-type oil separator in a cooling system including a compressor that pumps a mixture of lubricating oil and refrigerant through the filter-type oil separator. The filter type oil separator is configured to receive a first portion of the mixture from the compressor, and a bypass line is configured to bypass a second portion of the mixture around the filter-type oil separator. The bypass line ensures a sufficient amount of oil is present in the compressor.
Claims20
A system improving efficiency of a filter-type oil separator, the system comprising:
- a compressor configured to compress and pressurize a mixture of refrigerant and lubricant;
- a filter-type oil separator configured to receive a first portion of the compressed mixture of refrigerant and lubricant from the compressor;
- and
- a bypass line configured to bypass a second portion of the compressed mixture of refrigerant and lubricant around the filter-type oil separator.
A non-transitory computer-readable medium storing thereon sequences of computer-executable instructions to instruct a controller to:
- command a compressor to compress and pressurize a mixture of refrigerant and lubricant, the compressor being coupled to a bypass line including a bypass valve, and the compressor being coupled to a filter-type oil separator configured to receive a first portion of the compressed mixture of refrigerant and lubricant from the compressor;
- process one or more input signals;
- determine a speed value of the compressor based on the one or more input signals;
- and
- adjust the bypass valve included in the bypass line based on the speed value, the bypass line being configured to bypass a second portion of the compressed mixture of refrigerant and lubricant around the filter-type oil separator.
A method of improving efficiency of a filter-type oil separator in a system including a compressor, a 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;
- and
- bypassing a second portion of the compressed mixture of refrigerant and lubricant around the filter-type oil separator with the bypass line.
