Abstract
Two motor-compressor units of the vertical shaft type are housed in spaced parallel relation in a common sealing housing. A hollow chambered partition extends transversely within the housing between the units and is attached to the side walls and top wall but spaced from the bottom wall. The partition functions as a suction gas header, substantially isolates the suction areas above the oil level, and stiffens the housing walls, inhibiting resonant vibration.
Claims16
A hermetic multi-unit refrigeration motor-compressor assembly comprising in combination with a sealed metallic housing having top, bottom and side walls, a pair of motor-compressor units in spaced parallel relation in the housing, characterized by a partitioning member extending transversely within the housing between said units to define two compartments, each of which contains one of said units, the partitioning member being affixed to the side walls and top wall but substantially spaced above the bottom wall of the housing, whereby the bottom portion of the housing defines a common oil sump area.
A hermetic multi-unit refrigeration motor-compressor assembly comprising in combination with a sealed metallic housing having top, bottom and side walls, a pair of motor-compressor units in spaced parallel relation in the housing, characterized by a partitioning member extending transversely within the housing between said units to define two compartments, each of which contains one of said units, the partitioning member being affixed to the side walls and having an accumulator chamber therein.
A hermetic multi-unit refrigeration motor-compressor assembly comprising in combination with a sealed metallic housing having top, bottom and side walls, a pair of motor-compressor units in spaced parallel relation in the housing, characterized by a partitioning member extending transversely within the housing between said units, to define two compartments, each of which contains one of said units, the partitioning member being affixed to the side walls and top wall and containing a chamber defining an accumulator in fluid-conductive communication with both of the compressors.
