Abstract

943,490. Refrigerating. GARRETT CORPORATION. May 31, 1960 [June 1, 1959], No. 19263/60. Heading F4H. [Also in Division F1] In a closed-circuit refrigerating system, vapour can be returned from the condenser 6 to the inlet of the centrifugal compressor 1 via a bypass pipe 12. The flow through pipe 12 is controlled in accordance with the flow through the compressor discharge pipe 5 by means of a valve 13 actuated by a diaphragm 31 exposed on opposite sides to the pressures developed in a Pitot tube 34 and a static tube 33. Alternatively, the control is in accordance with pressure or temperature. The by-passed vapour enters the compressor inlet through nozzles 15 which impart a tangential component of flow to induce swirl in the incoming vapour. If the swirl is in the direction of rotation of the compressor impeller, it causes the compressor head to vary substantially in proportion to the load. If the swirl is in the opposite direction, the compressor head remains substantially constant. The nozzles 15 may be adjustable in direction.
