摘要： A compressor (90) includes a male rotor (42) which is axially aligned with and in communication with two female rotors (44, 46). The male rotor is driven by a motor (92), in other words the male rotor is the drive rotor. The male rotor has a plurality of lobes (48-55) which intermesh with a plurality of flutes (56-67) on each of the female rotors. The male rotor comprises an inner cylindrical metal shaft (82) with an outer composite material ring (84) mounted thereon. The ring includes the lobes of the male rotor integrally depending therefrom. The lobes of the male rotor being comprised of a composite material allows positioning of the female rotors at a small clearance from the male drive rotor. This clearance is small enough that the liquid refrigerant itself provides sufficient sealing, cooling and lubrication. The positioning of the female rotors on opposing sides of the male rotor balances the radial loading on the male rotor thereby minimizing radial bearing loads.

摘要翻译：根据本发明的压缩机包括与两个母转子轴向对齐并与之连通的公转轮。阳转子由电动机驱动，换句话说，阳转子是驱动转子。阳转子具有多个叶片，其与每个母转子上的多个凹槽相互啮合。阳转子包括安装在其上的外部复合材料环的内圆柱形金属轴。环包括与其一体地悬挂的阳转子的凸角。阳转子的凸起由复合材料构成，允许阴转子与阳传动转子间隔很小。该间隙足够小，使得液体制冷剂本身提供足够的密封，冷却和润滑。阴转子在阳转子的相对侧上的定位平衡了阳转子上的径向负载，从而使径向轴承负载最小化。操作期间公转轮与转子之间的界面速度较低，因此减少了由于润滑损失而造成的损坏。压缩机包括具有入口壳体部分，主壳体部分和排出壳体部分的壳体。感应侧板和排出侧板安装在阳转子上。感应板的外径等于公转子的根直径。排出板的外径等于公转子的峰值直径。这些板具有两个目的，以固定阳转子部件并且使雄转子两端的吸入压力相等，从而实际上消除了推力负载。放电端口限定在放电容纳部分中，其中提供陷阱袋释放。

摘要： A boosted air source heat pump system is presented having a primary compressor (24), a booster compressor (22) and an economizer (28). On activation of the heat pump system, the primary compressor (24) is operated. When the primary compressor (24) cannot meet the demand, the booster compressor (22) is activated, but only upon receipt of a signal enabling the operation of the booster compressor (22). The booster compressor (22) is preferably a variable speed booster, and its speed is controlled to be at or between an absolute minimum speed at an absolute maximum speed. The booster (22) may be on the low side or the high side of the primary compressor (24). The operation of the economizer (28) may be modulated to meet the demand on the system.

The pressure sensor functions as an override and safety control to prevent or permit operation of the compressors, and also other system components, depending on outside air temperature. The primary compressor is preferably a multi-capacity compressor. A defrost energy transfer fluid is used in a defrost cycle.
