ABSTRACT:
A variable capacity multiple compressor refrigeration system having a hermetic shell containing a first compressor intended to be always running when the system is operating and a second compressor that may be cycled on and off when the system is operating. The separate compressors are mounted to provide a unitary structure resiliently isolated from the common shell. The compressors are arranged in the shell so that their lower bearing portions are always below the level of oil in the sump area of the shell. Both compressors are arranged in the system through common compressor shell inlet and discharge openings.
