THE CONTROLLED ROTARY VANE GAS-HANDLING MACHINE.

Author(s) : EDWARDS T.

Summary

THE CONTROLLED ROTARY VANE MACHINE IS RELATED TO CONVENTIONAL SLIDING VANE COMPRESSORS, EXCEPT THAT THE MOTION OF THE VANES IS CONTROLLED: THE VANE TIPS CLOSELY APPROACH BUT DO NOT CONTACT THE INTERIOR OF THE STATOR CONTOUR ; THE VISCO-INERTIAL EFFECT OF THE CIRCULATING LUBRICANT AIDS IN SEALING. SUCH COMPRESSOR DESIGN YIELDS AN EFFICIENT AND COMPACT MACHINE SUITABLE FOR OPERATING WITH LOW DENSITY GASES. LABORATORY AND FIELD TESTING HAS DEMONSTRATED SIGNIFICANT PERFORMANCE ENHANCEMENTS RESULTING FROM DECOUPLING VANE MOTION FROM THE STATOR CONTOUR. A COMPRESSOR USING R114 DEMONSTRATED A COP OF 4.67 WHILE OPERATING ACROSS A STANDARD TEST CONDITION: 280-322 K (7-49 DEG C). THE OVERALL ISENTROPIC EFFICIENCY CLOSELY APPROACHES 80% AND A VOLUMETRIC EFFICIENCY OF NEARLY 90%.
