    Abstract: A variable capacity screw compressor comprises a suction port, at least two screw rotors and a discharge port being configured in relation to a selected rotational speed that operates at least one screw rotor at an optimum peripheral velocity that is independent of a peripheral velocity of the at least one screw rotor at a synchronous motor rotational speed for a rated screw compressor capacity. A motor is configured to drive the at least one screw rotor at a rotational speed at a full-load capacity that is substantially greater than the synchronous motor rotational speed at the rated screw compressor capacity. A variable speed drive receives a command signal from a controller and generates a control signal that drives the motor at the selected rotational speed.

    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: 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.

    Abstract: A scroll compressor and methods of assembling the scroll compressor are disclosed. The scroll compressor includes a frame aligned about a longitudinal axis of the scroll compressor, the frame including a plurality of extensions extending radially from the longitudinal axis, the plurality of extensions including axially extending frame interlock mechanisms. A fixed scroll support is aligned about the longitudinal axis, the fixed scroll support including a plurality of extensions extending radially from the longitudinal axis, the plurality of extensions including axially extending fixed scroll support interlock mechanisms configured to engage the frame interlock mechanisms upon radial rotation. A fixed scroll wrap is integral with or attached to the fixed scroll support.

    Abstract: Methods, systems, and apparatuses are disclosed to isolate operation vibration of a compressor to reduce operational sound. A compressor may include an external shell, and one or more isolators that separate a compression mechanism of a compressor from the external shell. The isolator can help isolate the vibration of the compression mechanism from the external shell. The isolator can also support a weight of the compression mechanism. The external shell can also include one or more internal seals. The internal seals can help separate a low-pressure side (e.g., a suction side) and a high-pressure side (e.g., a discharge side) of the compression mechanism. The compressor may also include a pressure balancing mechanism configured to help reduce a pressure difference between, for example, two ends of the compression mechanism, so as to reduce/eliminate the compression mechanism from physical shift in position due to the pressure difference.
