<p>A compact refrigeration unit supported by a generally rectilinear frame structure with front and back frame members having their axial planes spaced apart along the long axis of the frame is provided with a first selectively energized prime mover positioned within the frame with its relatively long rotary drive shaft in alignment with the long axis of the frame and a second selectively energized prime mover positioned within the frame with its relatively short rotary drive shaft extending from front to back frame member planes at right angles to the shaft of said first prime mover, there being clutch means to connect said first prime mover to a refrigerant compressor within said frame to drive said compressor when said first prime mover is energized and said clutch is engaged and there being right angel drive means including flexible connections to connect said compressor and said second prime mover to drive said compressor when said second prime mover is energized and said first prime mover is deenergized with said clutch disengaged.</p> |
