THE CENTRIFUGAL ECONOMISER: ITS MATCH WITH SCREW COMPRESSORS.

Author(s) : ZIMMERN B., SWEETSER R. S.

Summary

THE APPLICATION OF ECONOMISERS IS WELL KNOWN. DUE TO THE THERMODYNAMIC CHARACTERISTICS OF REFRIGERANTS, THE HIGHER THE PRESSURE RATIO THE MORE BENEFICIAL ARE THE EFFECTS OF UTILIZING AN ECONOMISER. THE PAPER PRESENTS THE APPLICATION OF A CENTRIFUGAL SEPARATOR IN COMBINATION WITH A CONTROL VALVE (CENTRIFUGAL ECONOMISER), WHICH HAS BEEN APPLIED AS AN INTEGRAL PART OF AN OIL-INJECTION-FREE SINGLE SCREW COMPRESSOR. THIS CENTRIFUGAL ECONOMISER COMPONENT CAN BE APPLIED TO SCREW COMPRESSORS WITH EXPECTED CAPACITY IMPROVEMENT OF 26% AND EFFICIENCY IMPROVEMENT OF 12% (R22 AT PRESSURERTOO ) THE CENTRIFUGAL ECONOMISER CAN BE ADDED TO A SINGLE SCREW COMPRESSOR VIRTUALLY AT NO ADDITIONAL COST SINCE ITS COST IS OFFSET BY THE COMPRESSOR SIZE REDUCTION.
