| 摘要 | A multiple compressor refrigeration system having at least first and second hermetic shell compressors with the suction line of the system connected into the upper portion of the first compressor shell and a suction line extending from within the upper portion of the first compressor shell to within the upper portion of the shell of the second compressor and with the discharge lines of the first and second compressors connected in parallel to the high pressure line of the system. An oil equalizing conduit is connected between the crankcase portions of the shells of the first and second compressors at the height of the minimum desired oil level to be maintained in the first compressor when both compressors are running with normal quantities of oil in the system. | ||||||
