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.
