Abstract: An eductor system for a chiller assembly is provided. The system includes a first and a second eductor. The first eductor includes a first suction inlet that receives a first oil and refrigerant mixture from a plenum of a compressor, a first motive inlet that receives a first motive fluid from an oil sump, and a first outlet that discharges a first outlet mixture to the oil sump. The first outlet mixture includes both the first oil and refrigerant mixture and the first motive fluid. The second eductor includes a second suction inlet that receives a second oil and refrigerant mixture from an evaporator, a second motive inlet that receives a second motive fluid from a condenser, and a second outlet that discharges a second outlet mixture to the plenum of the compressor. The second outlet mixture includes both the second oil and refrigerant mixture and the second motive fluid.
