Abstract: This disclosure relates to a compressor having a shaft, wherein the shaft is hollow to define a fluid passage extending along the shaft and a motor arranged along the shaft. A motor cooling line is configured to convey a cooling fluid to the motor, wherein the motor cooling line is fluidly connected to the fluid passage. The compressor may be a refrigerant compressor used in a heating, ventilation, and air conditioning (HVAC) chiller system.

Abstract: An example refrigerant system according to an exemplary aspect of this disclosure includes, among other things, a refrigerant loop having at least a condenser, an evaporator, and a compressor. The compressor includes a motor in communication with a variable speed drive. The system further includes a cooling circuit including a pressure regulator downstream of a heat exchanger, the heat exchanger absorbing heat from the variable speed drive.

Abstract: A centrifugal compressor for a refrigeration system is disclosed. The centrifugal compressor includes an electric motor, which includes a rotor and a stator. The compressor further includes a housing enclosing the electric motor, a stator cooling passage provided within the housing, and a rotor cooling passageway provided within the housing. The rotor cooling passageway is independent of the stator cooling passageway.

Abstract: This disclosure relates to a control system and method for the centrifugal compressor. The system, for example, includes a controller configured command an adjustment of at least one of (1) a flow regulator and (2) a speed of a shaft in order to provide safe, efficient compressor operation. Centrifugal compressors are used to circulate refrigerant in a chiller via a refrigerant loop. Centrifugal compressors operate efficiently before reaching a condition known as surge.
