摘要： A refrigeration system includes a compressor for compressing a refrigerant, a condenser for cooling the refrigerant, an evaporator for heating the refrigerant, and a lubrication system for providing a lubricant mist to a movable component of the compressor. The lubrication system includes an ejector arranged in fluid communication with the compressor and the evaporator, wherein the lubricant mist is carried by the refrigerant to the movable component.

摘要： A dual refrigeration circuit watercooled chiller has its respective evaporators and condensers interconnected by waterboxes such that the first circuit tubes discharge into the respective waterbox and the flow of water then passes from the respective waterboxes to the respective evaporator/condenser tubes of the second circuit. Instrumentation is attached to the waterboxes to enable the measurement of the leaving temperature differential to provide improved control. Since the first and second circuit tubes are separate and independent, both serviceability and flexibility in design are substantially enhanced.
摘要翻译：双制冷回路水冷式冷水机具有各自的蒸发器和冷凝器，其通过水箱互连，使得第一回路管排放到相应的水箱中，然后水流从相应的水箱传送到第二回路的相应的蒸发器/冷凝器管。仪器连接到水箱，以便测量离开温差，以提供改进的控制。由于第一和第二电路管是独立且独立的，所以设计中的可服务性和灵活性都大大提高。

摘要： In one aspect, a refrigeration system is provided. The refrigeration system includes a compressor coupled to a variable frequency drive (VFD), a condenser, an evaporator, an oil separator, and an oil conditioning circuit. The oil conditioning circuit is thermally coupled to the VFD and configured to heat oil from the oil separator with heat produced by the VFD.

摘要： A compressor (20) comprises: a housing assembly (22) having a plurality of ports including a suction port (24) and a discharge port (26); a male rotor (30) mounted for rotation about an axis (500); a female rotor (32) enmeshed with the male rotor and mounted in the housing for rotation about an axis (502) for drawing a flow from the suction port, compressing the flow, and discharging the compressed flow through the discharge port. The housing assembly comprises: a motor case (54); and a cover (60) bearing the suction port. The cover comprises a unitary piece forming: a mounting portion (63) mounted to an adjacent end (55) of the motor case, said adjacent end being large enough to pass the motor; and a fitting portion (62) extending to a rim (66) at the suction port and bearing an external groove (200).
