Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a vessel configured to receive refrigerant from a condenser of the HVAC system, an evaporator configured to receive the refrigerant from the vessel, a first conduit configured to direct a first flow of the refrigerant to a first inlet of the evaporator, and a second conduit configured to direct a second flow of the refrigerant to a second inlet of the evaporator. The second inlet is above the first inlet relative to a vertical axis.

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: A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system includes a refrigerant loop having a compressor configured to circulate a refrigerant therethrough, a motor configured to drive rotation of the compressor, wherein the motor is a permanent magnet assisted synchronous reluctance (PMASR) motor, and a motor cooling system configured to direct a portion of the refrigerant from the refrigerant loop and through a housing of the PMASR motor to place the portion of the refrigerant in thermal communication with components of the PMASR motor.

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.
