Abstract: Methods, systems and apparatuses for mounting a motor rotor to a shaft of a compressor are disclosed. The shaft can include a rib region that is configured to form a press fit or a transition fit with the rotor bore. An end of the shaft can also include a plurality of crenulations that can be expanded outwardly in a radial direction relative to a centerline of the shaft. After the rotor is mounted onto the shaft, the crenulations can be expanded to eliminate the clearance between the shaft and the rotor to form a press fit with the rotor bore.
Abstract translation: 公开了一种用于将马达转子安装到压缩机的轴上的方法,系统和装置。 轴可以包括肋区域,其被构造成形成压配合或与转子孔的过渡配合。 轴的端部还可以包括可以相对于轴的中心线在径向方向上向外扩展的多个齿轮。 在将转子安装到轴上之后,可以扩大齿轮以消除轴和转子之间的间隙,以形成与转子孔的压配合。

Abstract: A heat transfer circuit includes a compressor, a condenser, an expander, and an evaporator. The compressor includes a shaft that is rotated to compress a working fluid and a gas bearing to support the shaft. A conduit is configured to supply a portion of the working fluid to the compressor to cool the gas bearing. A method of controlling a heat transfer circuit includes directing a working fluid through a main flow path of the heat transfer circuit that directs the working fluid through a compressor, a condenser, an expander, an evaporator, and back to the compressor. The method also includes suppling supplying a portion of the working fluid in the main flow path to the compressor to cool a gas bearing of the compressor.

Abstract: A heating, ventilation, air conditioning, and refrigeration (HVACR) system is disclosed. The HVACR system includes a refrigerant circuit. The refrigerant circuit includes a compressor, a condenser, an expansion device, and an evaporator fluidly connected. A controller is electronically connected to the compressor. The controller is configured to prevent the compressor from operating at a speed that is less than a minimum speed limit. A lubricant separator has an inlet fluidly connected between the compressor and the condenser and a plurality of outlets. A first of the plurality of outlets is fluidly connected to the condenser. A second of the plurality of outlets is fluidly connected to one or more components of the compressor to provide a lubricant to the one or more components.
