    Abstract: A lubricant supply system is for a compressor that compresses a first working fluid in a heat transfer circuit. The lubricant supply system includes a lubricant tank, a lubricant pathway for supplying lubricant from the lubricant tank to one or more bearings of the compressor, and a lubricant refrigeration system with a lubricant heater and a lubricant cooler. The lubricant heater configured to heat the lubricant discharged from the one or more bearings and the lubricant cooler configured to cool the lubricant flowing through the lubricant pathway. A method of lubricating a compressor includes heating the lubricant, directing the lubricant from a lubricant tank through a lubricant pathway to one or more bearings of the compressor, and cooling the lubricant passing through the lubricant pathway.

    Abstract: Systems and methods to clamp an impeller on a shaft in a centrifugal compressor. The embodiments as disclosed herein may include clamping individual impeller independently to the shaft, which may reduce the tolerance stack-up effect of a plurality of impellers. The impeller can be clamped to the shaft by positioning, for example, a relatively stiff support (e.g. a shaft locknut) on a front side of the impeller. The impeller can also be clamped to the shaft by a relatively flexible support to compensate for e.g. thermal expansion/contraction of the impeller. The embodiments as disclosed herein are particularly suitable for a multi-stage impeller.

    Abstract: Apparatuses, systems, and methods to regulate the temperature of lubricant are provided. The regulation of the lubricant temperature can include increasing or decreasing the temperature of the lubricant. More specifically, apparatuses and methods are disclosed to reduce the temperature of the lubricant before it is directed to a mechanical component for lubrication purposes.

    Abstract: A vibration isolation apparatus for an air conditioning system may include a flow passage, at least a portion of which has a convoluted structure. The flow passage may also be coupled to two stabilizing members. The vibration isolation apparatus may include a structural supporting member to retain the two stabilizing members. The rod may be isolated from the stabilizing members by vibration isolation members. The vibration isolation apparatus may be positioned in a refrigeration line between an outlet of a compressor and a refrigerant pipe. The stabilizing members, the convoluted flow passage and the vibration isolation members may attenuate the vibration generated by the compressor so as to reduce the vibration transmitted to the refrigerant pipe. The structural supporting member may enhance the structural strength of the vibration isolation apparatus to withstand the pressure of the compressed refrigerant.
