    Abstract: Systems and methods to isolate a vibration source (e.g., a compressor) externally are disclosed. The embodiments generally include preventing/reducing vibration and/or pulsation transmission from the vibration source by one or more functional/structural isolating members, and preventing/reducing sound radiated from the vibration source by one or more sound enclosures.

    Abstract: An exemplary system includes a compressor, a condenser, an expander, and an evaporator fluidly coupled to form a vapor-compression circuit, and an electric motor configured to drive the compressor. An inverter having a plurality of switching elements is configured to provide an output voltage to the electric motor through operation of the switching elements. A waste heat recovery circuit is configured to transfer waste heat from the inverter to a load. A controller is configured provide switching commands to the switching elements of the inverter. The controller is further configured to sense a condition of the system, determine a heat production requirement based at least in part upon the system condition, and to vary the number of switching commands per unit time based at least in part upon the heat production requirement.

    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: 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.
