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.

Abstract: In certain embodiments, a condenser includes a shell having a longitudinal axis, a first tube bundle disposed within the shell, and a subcooler component disposed within the shell beneath the first tube bundle. The subcooler component includes a rectilinear housing, a plurality of rectilinear grid support assemblies disposed within the rectilinear housing and spaced lengthwise along the axis of the shell, and a second tube bundle disposed within the rectilinear housing, wherein tubes of the second tube bundle are held in place within rectilinear grid channels of the rectilinear grid support assemblies.
