摘要： A cooling system provided for a motor powering a compressor in a vapor compression system. The cooling system includes a housing enclosing the motor and a cavity located within the housing. A fluid circuit has a first connection with the housing configured to provide a liquid or two phase cooling fluid to the motor. The two phase cooling fluid is separable into a vapor phase portion and a liquid phase portion. The fluid circuit further has a second connection with the housing to remove cooling fluid in fluid communication with the fluid circuit. The cooling fluid conveyed through the second connection is two phase cooling fluid. The fluid circuit further has a third connection with the housing for receiving and circulating in the cavity the vapor phase portion conveyed through the second connection.

摘要： Apparatus and methods are provided for cooling motors used to drive gas and air compressors. In particular, the cooling of hermetic and semi-hermetic motors is accomplished by a gas sweep using a gas source located in the low-pressure side of a gas compression circuit. The gas sweep is provided by the creation of a pressure reduction at the compressor inlet sufficient to draw uncompressed gas through a motor housing, across the motor, and out of the housing for return to the suction assembly. The pressure reduction is created by means provided in the suction assembly, such as a nozzle and gap assembly, or alternatively a venturi, located upstream of the compressor inlet. Additional motor cooling can be provided by circulating liquid or another cooling fluid through a cooling jacket in the motor housing portion adjacent the motor.
