Abstract: A vapor compression system includes a first conduit fluidly coupling a liquid collection portion of a condenser and an evaporator, where the first conduit is configured to direct a first flow of refrigerant from the condenser to a first inlet of the evaporator and a second conduit fluidly coupling the liquid collection portion of the condenser and the evaporator, where the second conduit is configured to direct a second flow of refrigerant from the condenser to a second inlet of the evaporator via gravitational force, and where the first inlet is disposed above the second inlet relative to a vertical dimension of the evaporator.

Abstract: In an embodiment of the present disclosure, a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system includes a variable speed drive (VSD) enclosure. The VSD enclosure includes a main drive line variable speed drive (VSD) configured to supply power to a motor, and an oil pump variable speed drive (VSD) configured to supply power to a pump. The pump is configured to supply oil to one or more moving parts of the HVAC&R system. Additionally or in the alternative to the oil pump VSD, the VSD enclosure includes a magnetic bearing controller and/or a magnetic bearing controller power supply. The magnetic bearing controller is configured to control magnetic bearings of the HVAC&R system.
